Report: Russian Rocket Carrying Mexican Satellite Crashes in Siberia

A Russian-built Proton rocket with a relay satellite blasts off from a launch pad in Kazakhstan (April 2014)
The Proton-M carrier rocket blasted off with the MexSat-1 communications satellite from the Baikonur cosmodrome in Kazakhstan



Excerpt from nytimes.com

MOSCOW — A Russian-made rocket ferrying a Mexican telecommunications satellite crashed in eastern Siberia minutes after its launching on Saturday, Russian news agencies reported, citing officials at the country’s space agency.

The Proton-M rocket was launched from the Baikonur Cosmodrome in Kazakhstan at 11:47 a.m. and crashed in the Chita region of Siberia about eight minutes later, the reports said.

The failure appeared to have occurred with the rocket’s third stage, which was intended to bring the satellite to an altitude of about 110 miles. At that point, it was supposed to be propelled by engines into geostationary orbit.

Instead, there was a catastrophic failure. The stream of telemetry data sent back by the rocket failed about a minute before the satellite was to enter orbit, the news agencies reported.

The Interfax agency quoted an unidentified official at Roscosmos, the Russian space agency, as saying there had been an “emergency engine shutdown of the third stage.”

The Proton rocket is the mainstay transporter for International Launch Services, a joint Russian-American satellite carrier business. The satellite, called Centenario, was being sent into orbit on behalf of Mexico’s Ministry of Communications and Transportation and had been manufactured by Boeing Satellite Systems.

According to a statement issued by International Launch Services before the launching, it was intended to provide “mobile satellite services to support national security, civil and humanitarian efforts and will provide disaster relief, emergency services, telemedicine, rural education and government agency operations.”

The Proton-M is regarded as a workhorse but has encountered numerous problems in its decades of service. In 2013, a leadership shake-up at Roscosmos was prompted in part by the fourth failed launch of a Proton-M rocket within three years.

Officials said further launchings would be suspended until the cause of Saturday’s crash was determined.

The Mexican ministry said International Launch Services would create a commission to investigate the accident.

It said the satellite loss was “100 percent” covered by insurance, a point that seemed aimed at a domestic population often skeptical of the government’s spending on big projects.

The ministry said it still planned to launch another communications satellite from Cape Canaveral, Fla., aboard a Lockheed Martin rocket in October.

Gerardo Ruiz Esparza, the transportation and communications secretary, said that the lost satellite and its launching were valued at $390 million.

“I regret the mission was not a success,” Mr. Esparza said. “If Mexico is joining in these high technologies, we are going to have to learn to live with the risks that are not uncommon in this industry. The benefit is not so much being in the space era so much as the service it could provide to Mexicans.”

6 Ways to Overcome a Soul-Crushing Life Challenge

May 8, 2015 / / 0 Comments




Excerpt from huffingtonpost.com

It was never in your life plan, certainly never predicted in your high school yearbook.
And yet, here you are. You've gone through a soul-sucking life experience and are suffering from the collateral consequences. Uncertainty, fear and disbelief rule the day. You keep waiting to wake up and find out this was all a bad dream.
The problem is that wishing, wanting and waiting don't help. Whether you're still in the midst of the storm or idling in the aftermath, the truth is that you have to reach down and make the decision that although you may have had no control over what happened to you, you do have control over how you respond and move forward. These six tips will help start you on that journey:
1. Don't Compare Your Blooper Reel to Other's Highlight Reel
At times it may seem like the grass is greener on the other side of the fence. Social media exacerbates this perception because people tend to show only their green patch of lawn and not their backyard full of weeds!
Wouldn't it be refreshing to see someone's perfect vacation pictures captioned: "Don't know how we're really going to pay for this; We're up to our ears in debt! The kids got carsick and puked in the rental car, and Jack and I haven't had sex for weeks! Wish you were here!"
The grass isn't always greener. Everyone has something in life they wish they could undo, redo or erase. They just don't post it on Facebook.
2. Realize That Sometimes You Have No Control Over What Happens to You
Like the saying goes, life is what happens to you when you are making other plans. I truly believe that things happen for you rather than to you to nudge you into growth. When something unexpected happens, ask yourself "What's the lesson here?"
3. Surrender to Your Situation
Surrendering doesn't mean giving in; it simply means you stop fighting the fact that the situation happened. Accept the fact that it occurred, that it sucks, and that yes, it probably was unfair and undeserved.
When you continually try to fight against a situation, it's like trying to swim against a rip current. You can fight it and end up exhausted and pulled out to sea, or you can accept that it is done, swim parallel to it and overcome it. You cannot change what has already occurred but you can change how you respond to it. This is the tipping point to taking your power back.
4. Understand That Your Coping Mechanisms May Be Holding You Hostage
It is natural to feel disbelief, anger and sadness, and to want to blame others for what you are going through. These coping mechanisms are designed to help you deal with the situation at hand. They are also a defense mechanism, a way to push back on the reality of the situation.
The problem is, when you get stuck defending, denying, and blaming, you form an endless loop of negative thoughts that won't stop spinning in your head. The part of your brain that is controlling the loop is your ego. When you learn to harness your ego, you can transform the way you think and move past these self-destructive thoughts.
5. Harness Your Ego
Your ego is part of your consciousness, and it competes with your higher self, or spirit, for control of your thoughts. Your ego is fear-based and your higher self is love-based. The two cannot coexist because the higher self simply does not recognize fear. Think of the ego as the darkness and the higher self as the light switch; once the light goes on darkness cannot exist.
The ego thrives on fear and separation in order to control your thoughts. It causes you to think you need to be better because you're not good enough or are lacking in some way. The egoic brain creates this fear of inferiority and you react by putting others down as a way to raise your sense of self-worth up.
You can recognize your ego at work when you are critical or judgmental of others, when you take on the role of victim, or when you blame others rather than looking inward. When you feel self-important, when you feel the need to be right, and when anger, jealousy, and self-importance take center stage, that's your ego, and it isn't helping you. It creates a false sense of self.
Once you are aware that your ego is talking, you have begun the process of winning the mind chatter war in your head. Your awareness helps you realize that you no longer have to react to the fear it is creating. Your thoughts are not you but are of the ego. Remember that your ego and your higher self cannot co-exist; When you recognize the ego it has to take a back seat to your higher self. You then can move above these thoughts and shift your perspective from negative thoughts to ones that serve you positively.
6. Create Calm and Gratitude
The ego loves for you to focus on your past, on what you lost. What if you shift the way you look at your situation and focus on what you gained as a result?
What did you learn as a result of the trial? Are you more compassionate, less judgmental? Is your house calmer or cleaner? Did you start taking better care of yourself emotionally or physically? Are you finally putting yourself first?
Focusing on what you are grateful for instead of what you lost is a mindset that creates a calmer, happier you. And that is something to be grateful for!

The sun unleashes its biggest flare of the year

May 7, 2015 / / 0 Comments




Excerpt from dailytimes.com.pk

The sun has unleashed its most powerful flare of the year causing radio blackouts throughout the Pacific region.

The enormous X-class solar flare peaked at 6:11pm ET yesterday from a sunspot called Active Region 2339 (AR2339).

Solar flares are powerful bursts of radiation that, when intense enough, can disturb the atmosphere in the layer where GPS and communications signals travel - and scientists say they could get more powerful in the future.

This latest flare is classified as an X2.7. X-class denotes the most intense flares, while the number provides more information about its strength.

Despite the recent radio blackouts, scientists say the flare is unlikely to cause any further major issues here on Earth.

‘Given the impulsive nature of this event, as well as the source location on the eastern limb of the sun, we are not expecting a radiation storm at Earth,’ scientists with the U.S. Space Weather Prediction Center (SWPC) in Boulder, Colorado.

‘We will be on the lookout for new imagery from the Nasa Soho [Solar and Heliospheric Observatory] mission to determine if there was an associated coronal mass ejection (CME) with this event,’ they added.

‘Given the same logic above, however, we do not expect there to be one that would impact Earth.’

Yesterday Kazunari Shibata, an astrophysicist from Kyoto University in Japan, said the sun has the potential to unleash a flare of such a magnitude that it would be larger than anything humans have ever seen.

At the Space Weather Workshop in Colorado, Shibata said ‘superflares,’ that contain energy 1,000 times larger than what we have seen could be on their way.

He said there is evidence of this happening every 800 to 5,000 years on Earth,

Scientists say such a solar ‘super-storm’ would pose a ‘catastrophic’ and ‘long-lasting’ threat to life on Earth.

A superflare would induce huge surges of electrical currents in the ground and in overhead transmission lines, causing widespread power outages and severely damaging critical electrical components.

The largest ever solar super-storm on record occurred in 1859 and is known as the Carrington Event, named after the English astronomer Richard Carrington who spotted the preceding solar flare.

This massive CME released about 1022 kJ of energy - the equivalent to 10 billion Hiroshima bombs exploding at the same time - and hurled around a trillion kilos of charged particles towards the Earth at speeds of up to 3000 km/s.

However, its impact on the human population was relatively benign as our electronic infrastructure at the time amounted to no more than about 124,000 miles (200,000 km) of telegraph lines.

Nasa has also released incredible footage showing the sun unleashing a huge lick of plasma that increased the star’s visible hemisphere by almost half.

The solar filament, which exploded on April 28 and 29, was suspended above the sun due to strong magnetic fields that pushed outwards.

Solar astronomers around the world had their eyes on this unusually large filament and kept track as it erupted.

Nasa’s animation involves images taken from the orbiting Solar and Heliospheric Observatory using its Large Angle Spectrometric Coronagraph.

The diameter of the animation is about 30 million miles (45 million km) at the distance of the sun, or half of the diameter of the orbit of Mercury.

The white circle in the centre of the round disk represents the size of the sun, which is being blocked by the telescope in order to see the fainter material around it.

Study says the universe may be a hologram

April 28, 2015 / / 0 Comments






Holograms are two-dimensional pictures that appear to the human eye as three-dimensional objects. Some scientists believe that our universe may behave similarly, existing as a sort of all-encompassing hologram.
As explained by Nature World News, “a mathematical description of the Universe actually requires one fewer dimension than it seems” according to the “holographic principle,” which would indicate that what appears to be a 3-D universe may actually “just be the image of 2-D processes on a huge cosmic horizon.”
Prior to this study, scientists looked into this holographic principle by applying their calculations to a universe presenting Anti de Sitter space. Anti de Sitter is the term used to describe space as having a hyperbolic shape, much like a saddle. This hyperbolic space shape behaves, mathematically, as special relativity would predict.
Special relativity is a theory put forth by Albert Einstein to describe the relationship between space and time, and is especially useful when studying very small particles moving at extreme speeds over cosmic distances. The concept of Anti de Sitter space assumes that spacetime itself is hyperbolic in its natural state, in the absence of matter or energy.
A team at the Vienne University of Technology looked at the holographic principle not in the usual Anti de Sitter space framework, but instead applied the principle to flat spacetime, as represents our physical universe.“Our Universe, in contrast, is quite flat – and on astronomic distances, it has positive curvature,” team member Daniel Grumiller said in a statement.
The team created several gravitational theories that apply to flat space to see if calculations regarding quantum gravity would indicate a holographic description as has occurred in former calculations with theories applied to Anti de Sitter space.
“If quantum gravity in a flat space allows for a holographic description by a standard quantum theory, then there must be physical quantities, which can be calculated in both theories – and the results must agree,” Grumiller said.
The team found that the amount of quantum entanglement required for gravitational theory models expressed the same value in flat quantum gravity as in a low dimensional field theory, showing that the theory of a holographic universe can be successfully applied to the reality of the relatively flat field of spacetime evident in our universe.
“This calculation affirms our assumption that the holographic principle can also be realized in flat spaces. It is evidence for the validity of this correspondence in our universe” team member Max Riegler said.
The results were published in the journal Physical Review Letters.

Did natural selection make the Dutch the tallest people on the planet?

April 9, 2015 / / 0 Comments

Dutch national women's field hockey team



Excerpt from news.sciencemag.org
ByMartin Enserink

AMSTERDAM—Insecure about your height? You may want to avoid this tiny country by the North Sea, whose population has gained an impressive 20 centimeters in the past 150 years and is now officially the tallest on the planet. Scientists chalk up most of that increase to rising wealth, a rich diet, and good health care, but a new study suggests something else is going on as well: The Dutch growth spurt may be an example of human evolution in action.
The study, published online today in the Proceedings of the Royal Society B, shows that tall Dutch men on average have more children than their shorter counterparts, and that more of their children survive. That suggests genes that help make people tall are becoming more frequent among the Dutch, says behavioral biologist and lead author Gert Stulp of the London School of Hygiene & Tropical Medicine.

"This study drives home the message that the human population is still subject to natural selection," says Stephen Stearns, an evolutionary biologist at Yale University who wasn't involved in the study. "It strikes at the core of our understanding of human nature, and how malleable it is." It also confirms what Stearns knows from personal experience about the population in the northern Netherlands, where the study took place: "Boy, they are tall."

For many years, the U.S. population was the tallest in the world. In the 18th century, American men were 5 to 8 centimeters taller than those in the Netherlands. Today, Americans are the fattest, but they lost the race for height to northern Europeans—including Danes, Norwegians, Swedes, and Estonians—sometime in the 20th century.

Just how these peoples became so tall isn't clear, however. Genetics has an important effect on body height: Scientists have found at least 180 genes that influence how tall you become. Each one has only a small effect, but together, they may explain up to 80% of the variation in height within a population. Yet environmental factors play a huge role as well. The children of Japanese immigrants to Hawaii, for instance, grew much taller than their parents. Scientists assume that a diet rich in milk and meat played a major role.

The Dutch have become so much taller in such a short period that scientists chalk most of it up to their changing environment. As the Netherlands developed, it became one of the world's largest producers and consumers of cheese and milk. An increasingly egalitarian distribution of wealth and universal access to health care may also have helped.

Still, scientists wonder whether natural selection has played a role as well. For men, being tall is associated with better health, attractiveness to the opposite sex, a better education, and higher income—all of which could lead to more reproductive success, Stulp says.
Yet studies in the United States don't show this. Stulp's own research among Wisconsinites born between 1937 and 1940, for instance, showed that average-sized men had more children than shorter and taller men, and shorter women had more children than those of average height. Taken together, Stulp says, this suggests natural selection in the United States pulls in the opposite direction of environmental factors like diet, making people shorter instead of taller. That may explain why the growth in average American height has leveled off.

Stulp—who says his towering 2-meter frame did not influence his research interest—wondered if the same was true in his native country. To find out, he and his colleagues turned to a database tracking key life data for almost 100,000 people in the country's three northern provinces. The researchers included only people over 45 who were born in the Netherlands to Dutch-born parents. This way, they had a relatively accurate number of total children per subject (most people stop having children after 45) and they also avoided the effects of immigration.

In the remaining sample of 42,616 people, taller men had more children on average, despite the fact that they had their first child at a higher age. The effect was small—an extra 0.24 children at most for taller men—but highly significant. (Taller men also had a smaller chance of remaining childless, and a higher chance of having a partner.)  The same effect wasn't seen in women, who had the highest reproductive success when they were of average height.  The study suggests this may be because taller women had a smaller chance of finding a mate, while shorter women were at higher risk of losing a child.

Because tall men are likely to pass on the genes that made them tall, the outcome suggests that—in contrast to Americans—the Dutch population is evolving to become taller, Stulp says. "This is not what we've seen in other studies—that's what makes it exciting," says evolutionary biologist Simon Verhulst of the University of Groningen in the Netherlands, who was Stulp's Ph.D. adviser but wasn't involved in the current study. Verhulst points out that the team can't be certain that genes involved in height are actually becoming more frequent, however, as the authors acknowledge.

The study suggests that sexual selection is at work in the Dutch population, Stearns says: Dutch women may prefer taller men because they expect them to have more resources to invest in their children. But there are also other possibilities. It could be that taller men are more resistant to disease, Stearns says, or that they are more likely to divorce and start a second family. "It will be a difficult question to answer.”

Another question is why tall men in Holland are at a reproductive advantage but those in the United States are not. Stulp says he can only speculate. One reason may be that humans often choose a partner who's not much shorter or taller than they are themselves. Because shorter women in the United States have more children, tall men may do worse than those of average height because they're less likely to partner with a short woman.

In the end, Stearns says, the advantage of tall Dutchmen may be only temporary. Often in evolution, natural selection will favor one trend for a number of generations, followed by a stabilization or even a return to the opposite trend. In the United States, selection for height appears to have occurred several centuries ago, leading to taller men, and then it stopped. "Perhaps the Dutch caught up and actually overshot the American men," he says.

The Story of Human Evolution Now Challenged

Story of Human Evolution Challenged


Excerpt from newhistorian.com

The history of the evolution of early humans has been challenged.
Until now, one of the most dominant theories about our evolution claimed that our genus, Homo, had evolved from smaller early humans becoming taller, heavier and longer-legged. This process eventually resulted in Homo erectus, which was able to migrate out of Africa and colonise Eurasia.

Whilst we know that small-bodied H. erectus, averaging less than five feet tall and weighing under 50 kilograms, were living in southern Europe by 1.77 million years ago, the origin of the larger body size associated with modern humans has been elusive.

The paucity of knowledge about the origins of larger members of the Homo genus is primarily a result of a lack of evidence. Previous estimates of body size had been based on well-preserved specimens which were easy to assign a species to. Since these samples are rare and disparate in terms of both space and time, little is known about geographical and chronological variation in the body sizes of the early Homo.

A joint study between the Universities of Cambridge and Tübingen has shown that increases in body size occurred thousands of years after H. erectus left Africa; this growth in Homo body sizes primarily took place in the Koobi Fora region in modern Kenya.

“The evolution of larger bodies and longer legs can thus no longer be assumed to be the main driving factor behind the earliest excursions of our genus to Eurasia,” said Manuel Will, co-author of the study which has been published in the Journal of Human Evolution.

By using tiny fragments of fossil, the team were able to estimate our earliest ancestors’ height and body mass. Their findings, rather surprisingly, indicate a huge diversity in body size; this is particularly surprising as the wide variation we see in humans today was thought to be a relatively recent development.

“If someone asked you ‘are modern humans 6 foot tall and 70kg?’ you’d say ‘well some are, but many people aren’t,’ and what we’re starting to show is that this diversification happened really early in human evolution,” said Dr Jay Stock, co-author of the study.

Stock and Will are the first scientists in 20 years to compare the body size of humans from between 2.5 and 1.5 million years ago. They are also the first to use fragmentary fossils – many as small as toes, none longer than 5cm – to estimate body sizes.

By comparing measurements of fossils from sites in Kenya, Tanzania, South Africa and Georgia, the researchers have revealed substantial regional variation in the size of early humans. Groups who lived in South African caves, for example, were 4.8 feet tall on average. Some of the skeletons found in Kenya’s Koobi Fora region would have stood nearly 6 feet tall, a height comparable to the average height of modern British males.
“Basically every textbook on human evolution gives the perspective that one lineage of humans evolved larger bodies before spreading beyond Africa. But the evidence for this story about our origins and the dispersal out of Africa just no longer really fits,” said Stock.

It appears that Stock and Will have rewritten the history of the development of early humans; diversity has deep roots amongst the Homo genus.
