What happens to your body when you give up sugar?

Excerpt from independent.co.uk
By Jordan Gaines Lewis


In neuroscience, food is something we call a “natural reward.” In order for us to survive as a species, things like eating, having sex and nurturing others must be pleasurable to the brain so that these behaviours are reinforced and repeated.
Evolution has resulted in the mesolimbic pathway, a brain system that deciphers these natural rewards for us. When we do something pleasurable, a bundle of neurons called the ventral tegmental area uses the neurotransmitter dopamine to signal to a part of the brain called the nucleus accumbens. The connection between the nucleus accumbens and our prefrontal cortex dictates our motor movement, such as deciding whether or not to taking another bite of that delicious chocolate cake. The prefrontal cortex also activates hormones that tell our body: “Hey, this cake is really good. And I’m going to remember that for the future.”
Not all foods are equally rewarding, of course. Most of us prefer sweets over sour and bitter foods because, evolutionarily, our mesolimbic pathway reinforces that sweet things provide a healthy source of carbohydrates for our bodies. When our ancestors went scavenging for berries, for example, sour meant “not yet ripe,” while bitter meant “alert – poison!”
Fruit is one thing, but modern diets have taken on a life of their own. A decade ago, it was estimated that the average American consumed 22 teaspoons of added sugar per day, amounting to an extra 350 calories; it may well have risen since then. A few months ago, one expert suggested that the average Briton consumes 238 teaspoons of sugar each week.
Today, with convenience more important than ever in our food selections, it’s almost impossible to come across processed and prepared foods that don’t have added sugars for flavour, preservation, or both.
These added sugars are sneaky – and unbeknown to many of us, we’ve become hooked. In ways that drugs of abuse – such as nicotine, cocaine and heroin – hijack the brain’s reward pathway and make users dependent, increasing neuro-chemical and behavioural evidence suggests that sugar is addictive in the same way, too.

Sugar addiction is real

Anyone who knows me also knows that I have a huge sweet tooth. I always have. My friend and fellow graduate student Andrew is equally afflicted, and living in Hershey, Pennsylvania – the “Chocolate Capital of the World” – doesn’t help either of us. But Andrew is braver than I am. Last year, he gave up sweets for Lent. “The first few days are a little rough,” Andrew told me. “It almost feels like you’re detoxing from drugs. I found myself eating a lot of carbs to compensate for the lack of sugar.”
There are four major components of addiction: bingeing, withdrawal, craving, and cross-sensitisation (the notion that one addictive substance predisposes someone to becoming addicted to another). All of these components have been observed in animal models of addiction – for sugar, as well as drugs of abuse.
A typical experiment goes like this: rats are deprived of food for 12 hours each day, then given 12 hours of access to a sugary solution and regular chow. After a month of following this daily pattern, rats display behaviours similar to those on drugs of abuse. They’ll binge on the sugar solution in a short period of time, much more than their regular food. They also show signs of anxiety and depression during the food deprivation period. Many sugar-treated rats who are later exposed to drugs, such as cocaine and opiates, demonstrate dependent behaviours towards the drugs compared to rats who did not consume sugar beforehand.
Like drugs, sugar spikes dopamine release in the nucleus accumbens. Over the long term, regular sugar consumption actually changes the gene expression and availability of dopamine receptors in both the midbrain and frontal cortex. Specifically, sugar increases the concentration of a type of excitatory receptor called D1, but decreases another receptor type called D2, which is inhibitory. Regular sugar consumption also inhibits the action of the dopamine transporter, a protein which pumps dopamine out of the synapse and back into the neuron after firing.
In short, this means that repeated access to sugar over time leads to prolonged dopamine signalling, greater excitation of the brain’s reward pathways and a need for even more sugar to activate all of the midbrain dopamine receptors like before. The brain becomes tolerant to sugar – and more is needed to attain the same “sugar high.”

Sugar withdrawal is also real

Although these studies were conducted in rodents, it’s not far-fetched to say that the same primitive processes are occurring in the human brain, too. “The cravings never stopped, [but that was] probably psychological,” Andrew told me. “But it got easier after the first week or so.”
In a 2002 study by Carlo Colantuoni and colleagues of Princeton University, rats who had undergone a typical sugar dependence protocol then underwent “sugar withdrawal.” This was facilitated by either food deprivation or treatment with naloxone, a drug used for treating opiate addiction which binds to receptors in the brain’s reward system. Both withdrawal methods led to physical problems, including teeth chattering, paw tremors, and head shaking. Naloxone treatment also appeared to make the rats more anxious, as they spent less time on an elevated apparatus that lacked walls on either side.
Similar withdrawal experiments by others also report behaviour similar to depression in tasks such as the forced swim test. Rats in sugar withdrawal are more likely to show passive behaviours (like floating) than active behaviours (like trying to escape) when placed in water, suggesting feelings of helplessness.
A new study published by Victor Mangabeira and colleagues in this month’s Physiology & Behavior reports that sugar withdrawal is also linked to impulsive behaviour. Initially, rats were trained to receive water by pushing a lever. After training, the animals returned to their home cages and had access to a sugar solution and water, or just water alone. After 30 days, when rats were again given the opportunity to press a lever for water, those who had become dependent on sugar pressed the lever significantly more times than control animals, suggesting impulsive behaviour.
These are extreme experiments, of course. We humans aren’t depriving ourselves of food for 12 hours and then allowing ourselves to binge on soda and doughnuts at the end of the day. But these rodent studies certainly give us insight into the neuro-chemical underpinnings of sugar dependence, withdrawal, and behaviour.
Through decades of diet programmes and best-selling books, we’ve toyed with the notion of “sugar addiction” for a long time. There are accounts of those in “sugar withdrawal” describing food cravings, which can trigger relapse and impulsive eating. There are also countless articles and books about the boundless energy and new-found happiness in those who have sworn off sugar for good. But despite the ubiquity of sugar in our diets, the notion of sugar addiction is still a rather taboo topic.
Are you still motivated to give up sugar? You might wonder how long it will take until you’re free of cravings and side-effects, but there’s no answer – everyone is different and no human studies have been done on this. But after 40 days, it’s clear that Andrew had overcome the worst, likely even reversing some of his altered dopamine signalling. “I remember eating my first sweet and thinking it was too sweet,” he said. “I had to rebuild my tolerance.”
And as regulars of a local bakery in Hershey – I can assure you, readers, that he has done just that.

Bees Do It, Humans Do It ~ Bees can experience false memories, scientists say

February 27, 2015 / / 0 Comments



Excerpt from csmonitor.com


Researchers at Queen Mary University of London have found the first evidence of false memories in non-human animals.

It has long been known that humans – even those of us who aren't famous news anchors – tend to recall events that did not actually occur. The same is likely true for mice: In 2013, scientists at MIT induced false memories of trauma in mice, and the following year, they used light to manipulate mice brains to turn painful memories into pleasant ones.

Now, researchers at Queen Mary University of London have shown for the first time that insects, too, can create false memories. Using a classic Pavlovian experiment, co-authors Kathryn Hunt and Lars Chittka determined that bumblebees sometimes combine the details of past memories to form new ones. Their findings were published today in Current Biology.
“I suspect the phenomenon may be widespread in the animal kingdom," Dr. Chittka said in a written statement to the Monitor.
First, Chittka and Dr. Hunt trained their buzzing subjects to expect a reward if they visited two artificial flowers – one solid yellow, the other with black-and-white rings. The order didn’t matter, so long as the bee visited both flowers. In later tests, they would present a choice of the original two flower types, plus one new one. The third type was a combination of the first two, featuring yellow-and-white rings. At first, the bees consistently selected the original two flowers, the ones that offered a reward.

But a good night’s sleep seemed to change all that. One to three days after training, the bees became confused and started incorrectly choosing the yellow-and-white flower (up to fifty percent of the time). They seemed to associate that pattern with a reward, despite having never actually seen it before. In other words, the bumblebees combined the memories of two previous stimuli to generate a new, false memory.

“Bees might, on occasion, form merged memories of flower patterns visited in the past,” Chittka said. “Should a bee unexpectedly encounter real flowers that match these false memories, they might experience a kind of deja-vu and visit these flowers expecting a rich reward.”

Bees have a rather limited brain capacity, Chittka says, so it’s probably useful for them to “economize” by storing generalized memories instead of minute details.

“In bees, for example, the ability to learn more than one flower type is certainly useful,” Chittka said, “as is the ability to extract commonalities of multiple flower patterns. But this very ability might come at the cost of bees merging memories from multiple sequential experiences.”

Chittka has studied memory in bumblebees for two decades. Bees can be raised and kept in a lab setting, so they make excellent long-term test subjects.

“They are [also] exceptionally clever animals that can memorize the colors, patterns, and scents of multiple flower species – as well as navigate efficiently over long distances,” Chittka said.

In past studies, it was assumed that animals that failed to perform learned tasks had either forgotten them or hadn’t really learned them in the first place. Chittka’s research seems to show that animal memory mechanisms are much more elaborate – at least when it comes to bumblebees.

“I think we need to move beyond understanding animal memory as either storing or not storing stimuli or episodes,” Chittka said. “The contents of memory are dynamic. It is clear from studies on human memory that they do not just fade over time, but can also change and integrate with other memories to form new information. The same is likely to be the case in many animals.”

Chittka hopes this study will lead to a greater biological understanding of false memories – in animals and humans alike. He says that false memories aren’t really a “bug in the system,” but a side effect of complex brains that strive to learn the big picture and to prepare for new experiences.

“Errors in human memory range from misremembering minor details of events to generating illusory memories of entire episodes,” Chittka said. “These inaccuracies have wide-ranging implications in crime witness accounts and in the courtroom, but I believe that – like the quirks of information processing that occur in well known optical illusions – they really are the byproduct of otherwise adaptive processes.”

“The ability to memorize the overarching principles of a number of different events might help us respond in previously un-encountered situations,” Chittka added. “But these abilities might come at the expense of remembering every detail correctly.”
So, if generating false memories goes hand in hand with having a nervous system, does all this leave Brian Williams off the hook?

“It is possible that he conflated the memories,” Chittka said, “depending on his individual vulnerability to witnessing a traumatic event, plus a possible susceptibility to false memories – there is substantial inter-person variation with respect to this. It is equally possible that he was just ‘showing off’ when reporting the incident, and is now resorting to a simple lie to try to escape embarrassment. That is impossible for me to diagnose.”

But if Mr. Williams genuinely did misremember his would-be brush with death, Chittka says he shouldn’t be vilified.

“You cannot morally condemn someone for reporting something they think really did happen to them,” Chittka said. “You cannot blame an Alzheimer patient for forgetting to blow out the candle, even if they burn down the house as a result. In the same way, you can't blame someone who misremembers a crime as a result of false memory processes."

Will new ruling finally free Lolita after 40 years in captivity at Miami Seaquarium?

February 5, 2015 / / 0 Comments



Excerpt from seattletimes.com

A decision to list the captive orca Lolita for federal protection is expected to set the stage for a lawsuit from advocates seeking the whale’s release.

Seattle Times staff reporter
A Puget Sound orca held for decades at Miami’s Seaquarium will gain the protection of the federal Endangered Species Act, a move expected to set the stage for a lawsuit from advocates seeking the whale’s release.

The National Oceanic and Atmospheric Administration (NOAA) announced Wednesday the decision to list Lolita as part of the southern resident killer whales of Puget Sound, which already are considered endangered under the federal act. 

Whale activists, who petitioned for this status, have long campaigned for Lolita’s return to Puget Sound. They hope the listing will provide a stronger legal case to release Lolita than did a previous lawsuit that centered on alleged violations of the federal Animal Welfare Act.

“This gives leverage under a much stronger law,” said Howard Garrett of the Whidbey Island based Orca Network, which hopes a San Juan Island cove will one day serve as the site for Lolita to re-enter the wild.

NOAA Fisheries officials on Wednesday described their decision in narrow terms, which set no broader precedents. It does not address whether Lolita should be released from the Seaquarium.
“This is a listing decision,” said Will Stelle, the NOAA Fisheries regional administrator for the West Coast. “It is not a decision to free Lolita.” 

Aquarium officials have repeatedly said they have no intention of releasing the orca. 

“Lolita has been part of the Miami Seaquarium family for 44 years,” said Andrew Hertz, Seaquarium general manager, in a statement. 

“Lolita is healthy and thriving in her home where she shares habitat with Pacific white-sided dolphins. There is no scientific evidence that ... Lolita could survive in a sea pen or the open waters of the Pacific Northwest, and we are not willing to treat her life as an experiment.”

Orcas, also known as killer whales, are found in many of the world’s oceans. The southern resident population, which spends several months each year in Puget Sound, is the only group listed in the U.S. under the Endangered Species. 

The three pods in the population were reduced by captures by marine parks between 1965 and 1975, NOAA says. Among them was a roundup in Penn Cove where seven whales were captured, including Lolita. 

The southern resident pods now number fewer than 80. Possible causes for the decline are reduced prey, pollutants that could cause reproductive problems and oil spills, according to NOAA Fisheries.
Under the Endangered Species Act, it is illegal to cause a “take” of a protected orca, which includes harming or harassing them.
Wednesday, NOAA officials said holding an animal captive, in and of itself, does not constitute a take. 

Orca activists are expected to argue in their lawsuit that Lolita's cramped conditions result in a prohibited take.

There is “rising public scorn for the whole idea of performing orcas,” said Garrett, who hopes Seaquarium will decide to release Lolita without a court order. 

But NOAA officials still have concerns about releasing captive whales, and any plan to move or release Lolita would require “rigorous scientific review,” the agency said in a statement.
The concerns include the possibility of disease transmission, the ability of a newly released orca to find food and behavior patterns from captivity that could impact wild whales.

NOAA said previous attempts to release captive orcas and dolphins have often been unsuccessful and some have ended in death.

Garrett said the plan for Lolita calls for her to be taken to a netted area of the cove, which could be enlarged later. She would be accompanied by familiar trainers who could “trust and reassure her every bit of the way,” he said. 

The controversy over releasing captive whales has been heightened by the experience of Keiko, a captive orca that starred in the 1993 movie “Free Willy,” about a boy who pushed for the release of a whale.

In 1998, Keiko was brought back to his native waters off Iceland to reintroduce him to life in the wild. That effort ended in 2003 when he died in a Norwegian fjord. 

Garrett, who visited Keiko in Iceland in 1999, said he was impressed by the reintroduction effort, and that there was plenty of evidence that Keiko was able to catch fish on his own.

“The naysayers predicted that as soon as he got into the (Icelandic) waters he would die, and wild orcas would kill him,” Garrett said. “He proved that 180-degrees wrong. He loved it.”

Mark Simmons, who for two years served as director of animal husbandry for the Keiko-release effort, has a different view. He says Keiko never was able to forage for fish on his own, and that he continued to seek out human contact at every opportunity. 

Simmons wrote a book called “Killing Keiko,” that accuses the release effort of leading to a long slow death for the orca, which he says lacked food and then succumbed to an infection.

“It’s not really the fact that Keiko died, but how he died,” Garrett said Wednesday.

Banned TED Talk: The Science Delusion ~ Is science way off about the nature of our reality?

January 21, 2015 / / 0 Comments



The following statement has been posted by Tedstaff at blog.ted.com: "After due diligence, including a survey of published scientific research and recommendations from our Science Board and our community, we have decided that Graham Hancock’s and Rupert Sheldrake’s talks from TEDxWhitechapel should be removed from distribution on the TEDx YouTube channel... All talks on the TEDxTalks channel represent the opinion of the speaker, not of TED or TEDx, but we feel a responsibility not to provide a platform for talks which appear to have crossed the line into pseudoscience.

Response to the TED Scientific Board’s Statement
Rupert Sheldrake
March 18, 2013
I would like to respond to TED’s claims that my TEDx talk “crossed the line into pseudoscience”, contains ”serious factual errors” and makes “many misleading statements.”
This discussion is taking place because the militant atheist bloggers Jerry Coyne and P.Z. Myers denounced me, and attacked TED for giving my talk a platform. I was invited to give my talk as part of a TEDx event in Whitechapel, London, called “Challenging Existing Paradigms.” That’s where the problem lies: my talk explicitly challenges the materialist belief system. It summarized some of the main themes of my recent book Science Set Free (in the UK called The Science Delusion). Unfortunately, the TED administrators have publically aligned themselves with the old paradigm of materialism, which has dominated science since the late nineteenth century.
TED say they removed my talk from their website on the advice of their Scientific Board, who also condemned Graham Hancock’s talk. Hancock and I are now facing anonymous accusations made by a body on whose authority TED relies, on whose advice they act, and behind whom they shelter, but whose names they have not revealed.
TED’s anonymous Scientific Board made three specific accusations:
Accusation 1:“he suggests that scientists reject the notion that animals have consciousness, despite the fact that it’s generally accepted that animals have some form of consciousness, and there’s much research and literature exploring the idea.”
I characterized the materialist dogma as follows: “Matter is unconscious: the whole universe is made up of unconscious matter. There’s no consciousness in stars in galaxies, in planets, in animals, in plants and there ought not to be any in us either, if this theory’s true. So a lot of the philosophy of mind over the last 100 years has been trying to prove that we are not really conscious at all.” Certainly some biologists, including myself, accept that animals are conscious. In August, 2012, a group of scientists came out with an endorsement of animal consciousness in “The Cambridge Declaration on Consciousness”. As Discovery News reported, “While it might not sound like much for scientists to declare that many nonhuman animals possess conscious states, it’s the open acknowledgement that’s the big news here.” (http://news.discovery.com/human/genetics/animals-consciousness-mammals-birds-octopus-120824.htm)
But materialist philosophers and scientists are still in the majority, and they argue that consciousness does nothing – it is either an illusion or an ”epiphenomenon” of brain activity. It might as well not exist in animals – or even in humans. That is why in the philosophy of mind, the very existence of consciousness is often called “the hard problem”.http://en.wikipedia.org/wiki/Hard_problem_of_consciousness
Accusation 2:“He also argues that scientists have ignored variations in the measurements of natural constants, using as his primary example the dogmatic assumption that a constant must be constant and uses the speed of light as example.… Physicist Sean Carroll wrote a careful rebuttal of this point.”
TED’s Scientific Board refers to a Scientific American article that makes my point very clearly: “Physicists routinely assume that quantities such as the speed of light are constant.”
In my talk I said that the published values of the speed of light dropped by about 20 km/sec between 1928 and 1945. Carroll’s “careful rebuttal” consisted of a table copied from Wikipedia showing the speed of light at different dates, with a gap between 1926 and 1950, omitting the very period I referred to. His other reference (http://micro.magnet.fsu.edu/primer/lightandcolor/speedoflight.html) does indeed give two values for the speed of light in this period, in 1928 and 1932-35, and sure enough, they were 20 and 24km/sec lower than the previous value, and 14 and 18 km/sec lower than the value from 1947 onwards.
1926: 299,798
1928: 299,778
1932-5: 299,774
1947: 299,792
In my talk I suggest how a re-examination of existing data could resolve whether large continuing variations in the Universal Gravitational Constant, G, are merely errors, as usually assumed, or whether they show correlations between different labs that might have important scientific implications hitherto ignored. Jerry Coyne and TED’s Scientific Board regard this as an exercise in pseudoscience. I think their attitude reveals a remarkable lack of curiosity.
Accusation 3:“Sheldrake claims to have “evidence” of morphic resonance in crystal formation and rat behavior. The research has never appeared in a peer-reviewed journal, despite attempts by other scientists eager to replicate the work.”
I said, “There is in fact good evidence that new compounds get easier to crystallize all around the world.” For example, turanose, a kind of sugar, was considered to be a liquid for decades, until it first crystallized in the 1920s. Thereafter it formed crystals everyehere. (Woodard and McCrone Journal of Applied Crystallography (1975). 8, 342). The American chemist C. P. Saylor, remarked it was as though “the seeds of crystallization, as dust, were carried upon the winds from end to end of the earth” (quoted by Woodard and McCrone).
The research on rat behavior I referred to was carried out at Harvard and the Universities of Melbourne and Edinburgh and was published in peer-reviewed journals, including the British Journal of Psychology and the Journal of Experimental Biology. For a fuller account and detailed references see Chapter 11 of my book Morphic Resonance (in the US) / A New Science of Life (in the UK). The relevant passage is online here: http://sciencesetfree.tumblr.com/
The TED Scientific Board refers to ”attempts by other scientists eager to replicate the work” on morphic resonance. I would be happy to work with these eager scientists if the Scientific Board can reveal who they are.
This is a good opportunity to correct an oversimplification in my talk. In relation to the dogma that mechanistic medicine is the only kind that really works, I said, “that’s why governments only fund mechanistic medicine and ignore complementary and alternative therapies.” This is true of most governments, but the US is a notable exception. The US National Center for Complementary and Alternative Medicine receives about $130 million a year, about 0.4% of the National Institutes of Health (NIH) total annual budget of $31 billion.
Obviously I could not spell out all the details of my arguments in an 18-minute talk, but TED’s claims that it contains “serious factual errors,” “many misleading statements” and that it crosses the line into “pseudoscience” are defamatory and false.

Is this the Loch Ness Monster? Scientists discover new species of "uniquely Scottish" boat-sized Jurassic reptile on Isle of Skye

January 12, 2015 / / 0 Comments




Excerpt 

A 14-foot long, dolphin-like ichthyosaur would have swum the warm, shallow seas near Scotland during the Jurassic period, according to scientists who have identified an entirely new species from a “very special” set of bones found by an amateur enthusiast in 1959 and given to Glasgow’s Hunterian Museum.

The largest group of palaeontologists ever to have worked together in Scotland believe fossil fragments of skulls, teeth, vertebrae and an upper arm bone would have belonged to a previously unknown type of long-extinct aquatic animal, named the Dearcmhara shawcrossi after Brian Shawcross, who recovered the fossils from the island’s Bearreraig Bay.

partly in homage to the history of the Hebrides and Skye, much of which was underwater during Jurassic times. Some reports have likened the predator to an ancestor of the Loch Ness monster.

“During the time of dinosaurs, the waters of Scotland were prowled by big reptiles the size of motor boats,” explained Dr Steve Brusatte, of the University of Edinburgh’s School of GeoSciences, who led the study.

“Their fossils are very rare, and only now, for the first time, we’ve found a new species that was uniquely Scottish.

“Without the generosity of the collector who donated the bones to a museum instead of keeping them or selling them, we would have never known that this amazing animal existed.

“We are honoured to name the new species after Mr Shawcross and will do the same if any other collectors wish to donate new specimens.”

The creature was near the top of the food chain 170 million years ago, preying on fish and other reptiles during an age when Skye was joined to the rest of the UK as part of a large island positioned between landmasses that gradually drifted apart to become Europe and North America.


“Not only is this a very special discovery, but it also marks the beginning of a major new collaboration involving some of the most eminent palaeontologists in Scotland,” said Dr Nick Fraser, of National Museums Scotland.

What to Do If You See a Pet Left Out in the Cold

It can be a crime to leave pets outside in extreme temperatures without food and shelter


Cold weather can be deadly for pets. As the temperature plummets in many parts of the country, The Humane Society of the United States sees a marked increase in the number of complaints about dogs and cats who have been left outside with no food or shelter.

We encourage you to contact local law enforcement agencies because pets left outside in extreme temperatures, especially without food and shelter, are at risk of hypothermia, frostbite and even death. Their owners are at risk of facing criminal charges.

The act of leaving a pet outside without food or adequate shelter often receives less attention than a violent attack against an animal, but neglect is a crime. "Especially in these cold months, it is important for people to bring their pets inside and for others to report neglected animals to law enforcement,” says Ashley Mauceri, HSUS manager for cruelty response, who fields these calls.


One of the most common forms of animal cruelty, cases of animals left outside in dangerous weather are investigated more by police and animal control agencies than any other form of animal abuse. Our most constant companions—dogs and cats—feel the effects of winter weather as much as we do, only they are often cast outside to weather the cold or a storm owing to a misconception that the fur on their backs will insulate them from suffering. Without proper shelter, food and water, these domesticated animals’ chances of survival in frigid temperatures is greatly decreased. Any pet owners who aren't sure what protections their pets need during cold weather can read our cold-weather advice for keeping pets safe.

While views on animal welfare vary from region to region, there are laws in place in every state to prevent needless suffering. Callers to The HSUS report numerous cases across the country of animals left out in the cold, but the organization is also working with an increasing number of law enforcement agencies that recognize the importance of intervention in these cases.


The facts


  • Animal neglect is considered a misdemeanor crime in all 50 states and Washington, D.C.
  • Felony penalties can be levied in Massachusetts and Oklahoma for any animal neglect case.
  • Felony charges can be applied in animal neglect resulting in death in California, Connecticut, Florida and Washington, D.C.

New fish species found at a depth of 5 miles in the Mariana Trench ~ Video

December 20, 2014 / / 0 Comments



Excerpt from natmonitor.com

An international team of researchers, during a survey of the Mariana trench has found a new species of fish and found evidence of other known species living at new depths.

The Mariana trench is the deepest known part of the ocean, far too deep for humans to visit. At the deepest part of the trench the water pressure would be the equivalent of “one person trying to support 50 jumbo jets” according to the National Oceanic and Atmospheric Association (NOAA).

The survey was conducted using the Hadal-Lander, a vehicle built in Aberdeen Scotland for deep sea research. The vehicle is equipped with a variety of high resolution cameras, scientific instruments and an array of small baited funnel traps used to lure and trap small animals.

The researchers deployed the craft an unprecedented 92 times along the trench at depths ranging from 5000 – 10,600 meters.
At a depth of 8145 meters the team observed a kind of snail fish, 500 meters deeper than any fish has been observed previously.
“This really deep fish did not look like anything we had seen before, nor does it look like anything we know of, it is unbelievably fragile, with large wing-like fins and a head resembling a cartoon dog,” said Dr Alan Jamieson from the University of Aberdeen in a statement.

During the expedition the team also captured images of a ‘supergiant’ amphipod. These extremely large crustacean was originally discovered in traps off of New Zealand in 2012 but has never before been observed in its natural habitat. Video footage collected by the team shows the animal swimming, feeding and fighting off predators. A number of other species were also filmed, setting new depth records for three fish families.

Are we sending aliens the right messages?

November 12, 2014 / / 0 Comments


(Nasa)


bbc.com

Artist Carrie Paterson has long dreamed of beaming messages far out to the emptiness of space. Except her messages would have an extra dimension – smell.

By broadcasting formulae of aromatic chemicals, she says, aliens could reconstruct all sorts of whiffs that help to define life on Earth: animal blood and faeces, sweet floral and citrus scents or benzene to show our global dependence on the car. This way intelligent life forms on distant planets who may not see or hear as we do, says Paterson, could explore us through smell, one of the most primitive and ubiquitous senses of all.
(Wikipedia)
It is nearly 40 years since the Arecibo facility sent messages out into space (Wikipedia)

Her idea is only the latest in a list of attempts to hail intelligent life outside of the Solar System. Forty years ago this month, the Arecibo radio telescope in Puerto Rico sent an iconic picture message into space – and we’ve arguably been broadcasting to aliens ever since we invented TV and radio.

However in recent years, astronomers, artists, linguists and anthropologists have been converging on the idea that creating comprehensible messages for aliens is much harder than it seems. This week, Paterson and others discussed the difficulties of talking to our cosmic neighbours at a conference called Communicating Across the Cosmos, held by Seti (Search for Extraterrestrial Intelligence). It seems our traditional ways of communicating through pictures and language may well be unintelligible – or worse, be catastrophically misconstrued. So how should we be talking to ET?

Lost in translation?

We have always wanted to send messages about humanity beyond the planet. According to Albert Harrison, a space psychologist and author of Starstruck: Cosmic Visions in Science, Religion and Folklore, the first serious designs for contacting alien life appeared two centuries ago, though they never got off the ground.

In the 1800s, mathematician Carl Gauss proposed cutting down lines of trees in a densely forested area and replanting the strips with wheat or rye, Harrison wrote in his book. “The contrasting colours would form a giant triangle and three squares known as a Pythagoras figure which could be seen from the Moon or even Mars.” Not long after, the astronomer Joseph von Littrow proposed creating huge water-filled channels topped with kerosene. “Igniting them at night showed geometric patterns such as triangles that Martians would interpret as a sign of intelligence, not nature.”

But in the 20th Century, we began to broadcast in earnest. The message sent by Arecibo hoped to make first contact on its 21,000 year journey to the edge of the Milky Way. The sketches it contained, made from just 1,679 digital bits, look cute to us today, very much of the ‘Pong’ video game generation.  Just before then, Nasa’s Pioneer 10 and 11 space probes each carried a metal calling card bolted onto their frame with symbols and drawings on the plaque, showing a naked man and woman.

Yet it’s possible that these kinds of message may turn out to be incomprehensible to aliens; they might find it as cryptic as we find Stone Age etchings.

Antique tech

“Linear drawings of a male and a female homo sapiens are legible to contemporary humans,” says Marek Kultys, a London-based science communications designer. ”But the interceptors of Pioneer 10 could well assume we are made of several separate body parts (i.e. faces, hair and the man’s chest drawn as a separate closed shapes) and our body surface is home for long worm-like beings (the single lines defining knees, abdomens or collarbones.).”

Man-made tech may also be an issue. The most basic requirement for understanding Voyager’s Golden Record, launched 35 years ago and now way out beyond Pluto, is a record player. Aliens able to play it at 16 and 2/3 revolutions a minute will hear audio greetings in 55 world languages, including a message of ‘Peace and Friendship’ from former United Nations Secretary General Kurt Waldheim. But how many Earthlings today have record players, let alone extraterrestrials?

Time capsule

Inevitably such messages become outdated too, like time capsules. Consider the case of the Oglethorpe Atlanta Crypt of Civilization – a time capsule sealed on Earth in 1940, complete with a dry martini and a poster of Gone With the Wind. It was intended as a snapshot of 20th Century life for future humans, not aliens, but like an intergalactic message, may only give a limited picture to future generations. When, in 61,000 years, the Oglethorpe time capsule is opened, would Gone With The Wind have stood the test of time?

Kultys argues that all these factors should be taken into account when we calculate the likelihood of communicating with intelligent life. The astronomer Frank Drake’s famous equation allows anyone to calculate how many alien species are, based on likely values of seven different factors. At a UK Royal Society meeting in 2010 Drake estimated there are roughly 10,000 detectable civilisations in the galaxy. Yet Kultys points out that we should also factor in how many aliens are using the same channel of communications as us, are as willing to contact us as we are them, whose language we hope to learn, and who are physically similar to us.

Another barrier we might consider is the long distance nature of trans-cosmos communication. It means that many years ‒ even a thousand ‒ could pass between sending a message and receiving a reply. Paterson sees romance in that. “Our hope for communication with another intelligent civilisation has a melancholic aspect to it. 
We are on an island in a vast, dark space. Imagine if communication… became like an exchange of perfumed love letters with the quiet agony of expectation... Will we meet? Will we be as the other imagined? Will the other be able to understand us?”

Ready for an answer?

Anthropologist John Traphagan of the University of Texas in Austin has been asking the same question, though his view is more cautious. "When it comes to ET, you'll get a signal of some kind; not much information and very long periods between ‘Hi, how are you?’ and whatever comes back. We may just shrug our shoulders and say 'This is boring’, and soon forget about it or, if the time lag wasn't too long, we might use the minimal information we get from our slow-speed conversation to invent what we think they're like and invent a kind concept of what they're after.”

While we have been sending out messages, we have not been preparing the planet for what happens when we get an interstellar return call. First contact could cause global panic. We might assume those answering are bent on galactic domination or, perhaps less likely, that they are peaceful when in fact they’re nasty.

Consider how easy it is to mess up human-to-human communications; I got Traphagan’s first name wrong when I e-mailed him for this article. An apology within minutes cleared up the confusion, yet if he had been an alien anthropologist on some distant planet it would have taken much longer to fix. He later confessed: "I could have thought this is a snooty English journalist and our conversation might never have happened."

Even if Earth’s interstellar messaging committees weeded out the typos, cultural gaffes are always a possibility. These can only be avoided by understanding the alien’s culture – something that’s not easy to do, especially when you’ve never met those you’re communicating with.

Rosy picture

So, what is the best way to communicate? This is still up for grabs – perhaps it’s via smell, or some other technique we haven’t discovered yet. Clearly, creating a message that is timeless, free of cultural bias and universally comprehensible would be no mean feat.

But for starters, being honest about who we are is important if we want to have an extra-terrestrial dialogue lasting centuries, says Douglas Vakoch, director of interstellar message composition at Seti. (Otherwise, intelligent civilisations who’ve decoded our radio and TV signals might smell a rat.)

“Let's not try to hide our shortcomings,” says Vakoch. “The message we should send to another world is straightforward: We are a young civilisation, in the throes of our technological adolescence. We're facing a lot of problems here on Earth, and we're not even sure that we'll be around as a species when their reply comes in. But in spite of all of these challenges, we humans also have hope – especially hope in ourselves."


Yet ultimately what matters, says Paterson, is that they stop and consider the beings who sent them a message; the people who wanted to say: “Here are some important things. Here’s our DNA, here is some maths and universal physics. And here is our longing and desire to say “I’m like you, but I’m different.”

An artist's rendition of the amphibious Cartorhynchus lenticarpus. (Stefano Broccoli)


In a Nov. 5th article penned by Rachel Feltman(washingtonpost.com) entitled Newly discovered fossil could prove a problem for creationists (But apparently not a really big problem), a report published in the journal Nature claims to have discovered the missing link proving that modern man has evolved from a sometimes aquatic, sometimes not, (he apparently changed his mind once or twice about which direction he wanted to evolve) little green fish/frog/alligator/lizardy type character named Cartorhynchus lenticarpus. Although I chuckled all through the unsubstantiated claims of the report's lead author Ryosuke Motani, one of my favorite moments had to be when Motani describes his brainstorming activity. "Initially I was really puzzled by this fossil. I could tell it was related [to ichthyosaurs], but I didn't know how to place it. It took me about a year before I was sure I had no doubts." (Wait Ryosuke, go back to that moment in time while you were kicking an empty soda can around your neighborhood while trying to figure out how you could pound a square green peg into a round hole. I think that's where your theory may have gone slightly askew.)

My absolute favorite moment of the study though had to be the team's conclusion that the foot and a half long green amphibian "probably had a happy life". I could see now a room full of white lab coats concurring with one another. "Yes yes, happy indeed. I concur." A young lab technician then sheepishly speaks up. "I must disagree sirs. My research shows its not easy being green." "Oh yes, yes," the group of senior scientists now concede. "Indeed, it's not easy being green." 

Motani's statement that his team now hopes to find the preceding evolutionary ancestor to Cartorhynchus lenticarpus as their next major breakthrough is the part of this report that I can't get out of my mind. What would the odds be that this small group of researchers not only find one crucial missing link, but will also discover the very next missing piece of the long evolutionary puzzle chain, evidence countless archeologists, scientists and researchers have been, for centuries, turning over stones in search of. Something smells fishy here, and it isn't the great, great, great grandfather of Kermit the Frog.

Excerpts from the washingtonpost.com article by Rachel Feltman:

Researchers report that they've found the missing link between an ancient aquatic predator and its ancestors on land. Ichthyosaurs, the dolphin-like reptiles that lived in the sea during the time of the dinosaurs, evolved from terrestrial creatures that made their way back into the water over time.

But the fossil record for the lineage has been spotty, without a clear link between land-based reptiles and the aquatic ichthyosaurs scientists know came after. Now, researchers report in Nature that they've found that link — an amphibious ancestor of the swimming ichthyosaurs named  Cartorhynchus lenticarpus.

"Many creationists have tried to portray ichthyosaurs as being contrary to evolution," said lead author Ryosuke Motani, a professor of earth and planetary sciences at the University of California Davis. "We knew based on their bone structure that they were reptiles, and that their ancestors lived on land at some time, but they were fully adapted to life in the water. So creationists would say, well, they couldn't have evolved from those reptiles, because where's the link?"

Now the gap has been filled, he said.

The creature is about a foot and a half long and lived 248 million years ago.

"Initially I was really puzzled by this fossil," Motani said. "I could tell it was related [to ichthyosaurs], but I didn't know how to place it. It took me about a year before I was sure I had no doubts."

One of the most important differences between this new ichthyosaur and its supposed descendants comes down to being big boned: When other vertebrates have evolved from land to sea living, they've gone through stages where they're amphibious and heavy. Their thick bones probably allowed them to fight the power of strong coastal waves and stay grounded in shallow waters. Sure enough, this new fossil has much thicker bones than previously examined ichthyosaurs.

"This animal probably had a happy life. It was in the tropics, and it was probably a bottom feeder that fed on soft-bodied things like squid and animals like shrimp," Motani said. "And for a predator like that to exist, there has to be plenty of prey. This was probably one of the first predators to appear after that extinction."

This single fossil hasn't revealed all of the ichthyosaurs' secrets. Motani hopes to find the preceding evolutionary ancestor next — one that was also amphibious, but spent slightly more of its time on land. "We're looking for that one now," Motani said.
