What Most Doctors Won’t Tell You About Cholesterol

August 6, 2015 / / 0 Comments

Dr. Ben Kim, GuestDuring my university years, I used to frustrate my parents by throwing away egg yolks and eating only the whites. No worries, I thought, as my parents just didn’t know enough to realize that I was reducing my risk of heart disease by avoiding cholesterol. Looking back, I’m sure that my parents were wondering how I could so easily toss away precious egg yolks that they were able afford only a few times a year when they lived in Korea.Today, I am grateful [...]

Astrophysicists Can Now Make Weather Forecasts For Distant Planets

May 12, 2015 / / 0 Comments


Exoplanet day/night cycle
Cloudy mornings and scorching hot afternoons: the Kepler space telescope has provided weather forecasts for some distant exoplanets.


Excerpt from techtimes.com

A telescope observing distant planets has found evidence of weather patterns, allowing astrophysicists to "forecast" their conditions.

Analyzing data from NASA's Kepler space telescope, a team of astrophysicists at universities in Canada and Great Britain has identified signs of daily weather variations on six exoplanets.
They observed phase variations as different parts of the planets reflected light from their host stars, in much the same way that our moon cycles though different phases.

"We determined the weather on these alien worlds by measuring changes as the planets circle their host stars, and identifying the day-night cycle," said Lisa Esteves from the Department of Astronomy and Astrophysics at the University of Toronto.

"We traced each of them going through a cycle of phases in which different portions of the planet are illuminated by its star, from fully lit to completely dark," added Esteves, who the led the team on the study.

The scientists have offered up "forecasts" of cloudy mornings for four of the planets, and clear but scorching hot afternoons on two others.

They based their predictions on the planets' rotations, which produce an eastward motion of their atmospheric winds. That would blow clouds that formed over the cooler side of one of the planets around to its morning side — thus producing the "cloudy" morning forecast.

"As the winds continue to transport the clouds to the day side, they heat up and dissipate, leaving the afternoon sky cloud-free," said Esteves. "These winds also push the hot air eastward from the meridian, where it is the middle of the day, resulting in higher temperatures in the afternoon."

The Kepler telescope has proven to be the ideal instrument for studying phase variations on distant exoplanets, according to the researchers.

The massive amounts of data and the extremely precise measurements that the telescope is capable of permits them to detect even tiny, subtle signals coming from the distant world, and to separate them from the almost overwhelming light coming from their host stars.

"The detection of light from these planets hundreds to thousands of light years away is on its own remarkable," said co-author Ernst de Mooij from the Astrophysics Research Centre from the School of Mathematics and Physics at Queen's University, Belfast.
"But when we consider that phase cycle variations can be up to 100,000 times fainter than the host star, these detections become truly astonishing."

There may come a day when a weather report for a distant planet is a common and unremarkable event, the researchers added.
"Someday soon we hope to be talking about weather reports for alien worlds not much bigger than Earth, and to be making comparisons with our home planet," said Ray Jayawardhana of York University in England.

This study was published in The Astrophysical Journal.

Is In-Flight Refueling Coming to Commercial Airlines?

April 12, 2015 / / 0 Comments




Excerpt from space.com

 This article was originally published on The Conversation. The publication contributed this article to Space.com's Expert Voices: Op-Ed & Insights.

There’s real pressure on the aviation industry to introduce faster, cheaper and greener aircraft, while maintaining the high safety standards demanded of airlines worldwide.

Airlines carry more than three billion passengers each year, which presents an enormous challenge not only for aircraft manufacturers but for the civil aviation infrastructure that makes this extraordinary annual mass-migration possible. Many international airports are close to or already at capacity. The International Air Transport Association (IATA) has estimated that, without intervention, many global airports – including major hubs such as London Heathrow, Amsterdam Schiphol, Beijing and Dubai – will have run out of runway or terminal capacity by 2020. 


The obvious approach to tackling this problem is to extend and enlarge airport runways and terminals – such as the long-proposed third runway at London Heathrow. However there may be other less conventional alternatives, such as introducing in-flight refuelling for civil aircraft on key long-haul routes. Our project, Research on a Cruiser-Enabled Air Transport Environment (Recreate), began in 2011 to evaluate whether this was something that could prove a viable, and far cheaper, solution.

If in-flight refuelling seems implausible, it’s worth remembering that it was first trialed in the 1920s, and the military has continued to develop the technology ever since. The appeal is partly to reduce the aircraft’s weight on take-off, allowing it to carry additional payload, and partly to extend its flight range. Notably, during the Falklands War in 1982 RAF Vulcan bombers used in-flight refuelling to stage what was at the time the longest bombing mission ever, flying 8,000 miles non-stop from Ascension Island in the South Atlantic to the Falklands and back.

Reducing take-off weight could offer many benefits for civilian aircraft too. Without the need to carry so much fuel the aircraft can be smaller, which means less noise on take-off and landing and shorter runways. This opens up the network of smaller regional airports as new potential sites for long-haul routes, relieving pressure on the major hubs that are straining at the seams.

There are environmental benefits too, as a smaller, lighter aircraft requires less fuel to reach its destination. Our initial estimates from air traffic simulations demonstrate that it’s possible to reduce fuel burn by up to 11% over today’s technology by simply replacing existing global long-haul flight routes with specifically designed 250-seater aircraft with a range of 6,000nm after one refuelling – roughly the distance from London to Hong Kong. This saving could potentially grow to 23% with further efficiencies, all while carrying the same number of passengers the same distance as is possible with the current aircraft fleet, and despite the additional fuel burn of the tanker aircraft.

Tornado fighter jets in-flight refuel
Imagine if these Tornado fighter jets were 250-seater passenger aircraft and you’ve got the idea.

However, this is not the whole picture – in-flight refuelling will require the aerial equivalent of petrol stations in order to deliver keep passenger aircraft in the sky. With so much traffic it simply wouldn’t be possible to refuel any aircraft any time, anywhere it was needed. The location of these refuelling zones, coupled with the flight distance between the origin and destination airports can greatly affect the potential benefits achievable, possibly pulling flights away from their shortest route, and even making refuelling on some routes impossible – if for example the deviation to the nearest refuelling zone meant burning as much fuel as would have been saved.

Safety and automation

As with all new concepts – particularly those that involve bringing one aircraft packed with people and another full of fuel into close proximity during flight – it’s quite right to ask whether this is safe. To try and answer this question, the Dutch National Aerospace Laboratory and German Aerospace Centre used their flight simulators to test the automated in-flight refuelling flight control system developed as part of the Recreate project.

One simulator replicated the manoeuvre from the point of view of the tanker equipped with an in-flight refuelling boom, the other simulated the aircraft being refuelled mid-flight. Critical test situations such as engine failure, high air turbulence and gusts of wind were simulated with real flight crews to assess the potential danger to the operation. The results were encouraging, demonstrating that the manoeuvre doesn’t place an excessive workload on the pilots, and that the concept is viable from a human as well as a technical perspective.

So far we’ve demonstrated the potential aerial refuelling holds for civilian aviation, but putting it into practice would still pose challenges. Refuelling hubs would need to be established worldwide, shared between airlines. There would need to be fundamental changes to airline pilot training, alongside a wider public acceptance of this departure from traditional flight operations.

However, it does demonstrate that, in addition to all the high-tech work going into designing new aircraft, new materials, new engines and new fuels, the technology we already have offers solutions to the long-term problems of ferrying billions of passengers by air around the world.

How will life on earth compare to life for the Mars One pioneers?

To infinity and beyond? Maggie Lieu

On a different planet - Nick Curtis imagines a message from 'Martianaut' Maggie Lieu to her parents back at home


Mars Mission, British Martianaut Maggie Lieu’s Log
Day One: Stardate 22/02/2025. 

Hello Mission Control.... Just kidding! Hi mum, hi dad, or should I say earthlings! 
Well, me and Bruce the Australian Martianaut finally touched down beside the Herschel II Strait on the red planet today, the last of 12 pairs to arrive - though as you know it was touch and go. Ten years of training and research almost went down the drain when Google got hit by a massive retrospective tax bill and had to withdraw all its branded sponsorship from the starship at the last minute: 

fortunately Amazon stepped in, on the agreement we install its first matter transference delivery portal (“It’s there before you know it”) here. And rename the ship Bezos 1, of course 
The trip was textbook, with both of us uploading videos on how to apply makeup and bake cupcakes in space direct to the Weibo-spex of our crowdsource funders in China - great practice for The Great Martian Bakeoff on BBC 12 next year (subscribers only). The one hairy moment was a near miss with that Virgin Galactic rocket, Beardie IV, that went AWOL five years ago. We were so close we could see Leonardo diCaprio’s little screaming face pressed against his porthole. And Kim Kardashian’s bum pressed against hers - though it’s looking kinda old now and I hoped we’d seen the last of it.


So what can I tell you? When we landed the others threw us a party with full fat milk, rare beef and waffles (the only official space superfoods since it was discovered that kale and quinoa cause impotence). The landscape is pretty barren, just acres of rolling sand and no one in sight, sort of like Greece after it left the Eurozone and the entire population moved to Germany. Or like the so-called Caliphate after Islamic State finally perfected its time machine and managed to transport itself and all its followers back to the 12th century. 

The temperature outside is about 20c, so a lot cooler than it is at home since the ice caps melted. There’s water here, but not as much as is now covering Indonesia, Holland and Somerset. The atmosphere is 96% carbon dioxide so Juan, the Spanish Martianaut, had to keep his suit on when he went out to smoke. He tried to get us all to buy duty free for him in Mexico City spaceport before we left, now that a pack of cigarettes costs 450 Euros in the shops, and they’ve been camouflaged so you can’t find them.

The construction-droids did a pretty good job building Mars Camp out of the recycled parts of all those closed Tesco Metros. They say we have enough air up here to last 20 years, Earth’s stocks of storable oxygen having increased tenfold when the European Parliament collapsed following the expenses scandal. I still can’t believe that Dasha Putin-Mugabe was claiming for SIX driverless cars while she was EU President, and employing her wife as her accountant. And her being the first transgender Russian lesbian to hold the office, too. 

Speaking of politics, how is life in coalition Britain? Who has the upper hand at the moment? UKIP? Scots Nats? The Greens? or those nutters from Cornwall, Mebion Kernow? Or are they underwater now. And how is young Straw doing now Labour is the smallest party in Parliament, after the New New New Conservatives? Hard to believe it’s three years since the last Lib Dem lost her seat. 

I gather that some things have improved internationally now that Brian Cox has developed his own time machine at the Wowcher-Hawking Institute in Cambridge, and worked out that the entire world can now transport all its waste products back to the Caliphate in the 12th century. 

We can see the Earth from here through the Clinton2020 Telescope that the US president endowed us with after her brief period in office. The joke up here is that she did it to keep a proper eye either on her husband (though he doesn’t get around so much any more, obviously) or on what President Palin is up to. I still can’t believe that she sold Alaska to Russia to pay the compensation bill for the Grand Canyon Fracking Collapse. 

Even through the Clinton2020 the Earth looks pretty small, though at times, when the stars are really bright, we can see the Great Wall 2 ring of laser satellites that China has pointed at Russia to discourage any more “accidental” incursions. 

Our team up here is like a microcosm of human life on earth. Well, up to a point. As you know the French and Italian Martianauts were expelled from the team before lift-off, because of some scandal or other. We weren’t told if it was financial or sexual but a space bra and a data stick with three million Bitcoins on it were found in the airlock. 

The African and Brazilian Martianauts swan around the place as if they PERSONALLY solved the world’s food and energy problems.
And the North Korean guy just sits in the corner, muttering into some device up his sleeve and scowling. All the freeze-dried cheese has gone and he’s looking quite fat, if you get my meaning. 

I don’t get much time to myself, what with work, the non-denominational Sorry Meetings where we apologise in case we’ve accidently offended someone’s beliefs, and the communal space-pilates sessions (the North Korean guy skips those so he may be in line for a compulsory gastric band, as mandated by the Intergalactic Health Organisation). 

I always try and upload the latest Birmingham City Games onto my cortex chip when I feel homesick: I know it's not fashionable, but I think football got better when they replaced the players with robots and the wage bill - and the number of court cases - dropped to zero. I know the electricity bill is massive, but the new Brazilian solar technology should fix that. 

Anyway, got to run now. We’re putting together a bid to have the 2036 Olympics up here. 

Bye, or as we say on Mars - see you on the dark side.

Mysterious plumes in Mars’ atmosphere baffle astronomers

February 17, 2015 / / 0 Comments




Excerpt from thespacereporter.com

Astronomers are baffled by images of plumes rising from Mars’ atmosphere in images taken by amateur astronomers in March and April 2012.

The plumes were present for about 10 days though their shapes and sizes changed rapidly during that time, from finger-like tendrils to spherical blobs.

Researchers have proposed several possible explanations for the plumes, which are discussed in an article just published in the journal Nature.

Each of the theories being considered poses problems. One theory, for instaqnce, proposes the plumes are caused by the same magnetic influence that causes the aurora borealis, or Northern Lights, on Earth. The movement of electrically charged particles from the Sun, driven by the solar wind towards Earth’s poles, results in these particles colliding with molecules of gas. These collisions produce the strange lights known as aurorae.

In the study, the researchers admit, “Mars aurorae have been observed near where the plume occurs, a region with a large anomaly in the crustal magnetic field that can drive the precipitation of solar wind particles into the atmosphere.”
The problem with this theory is this would only happen if the Sun released an exceptional amount of energetic particles during the time the plumes were seen. Yet the level of solar output in 2012 was nowhere near sufficient to release such a powerful stream of particles, the authors of the paper acknowledge.

They move on to consider another option, namely that the plumes might be clouds high in the Martian atmosphere.

A highly reflective cloud of either water ice, carbon dioxide ice, or dust particles could explain the plumes. But according to computer models, the presence of these clouds “would require exceptional deviations from standard atmospheric circulation models to explain cloud formations at such high altitudes,” explained the paper’s lead author, Agustin Sanchez-Lavega of the Universidad del Pais Vasco in Spain.

The plumes were seen approximately 120 miles (200 km) from Mars’ surface, which is problematic because the highest Martian clouds are seen is 60 miles (100 km) above the planet’s surface. The only way water can condense so far up is if the temperature in that part of Mars’ atmosphere drops 370 degrees Fahrenheit, or 50 degrees Kelvin, below its norm.

Condensation of carbon dioxide would require twice this temperature drop.

A third theory posits the flumes are caused by atmospheric dust. A wind powerful enough to transport dust 111 miles (180 km) above Mars’ surface could occur only around noon, when the Sun’s heat would be strong enough to create such wind currents.

However, the plumes were seen not at noon but in the mornings along the terminator that separates the planet’s day and night sides.
Recently, data from the Hubble Space Telescope was found showing the plumes back in 1997.

A ‘bionic leaf’ that turns sunlight into fuel

February 11, 2015 / / 0 Comments


Excerpt from cnbc.com

By Robert Ferris



The invention could pave the way for numerous innovations—by converting solar power into biofuels, it may help solve the vexing difficulty of storing unused solar energy, which is one of the most common criticisms of solar power as a viable energy source.
The process could also help make plastics and other chemicals and substances useful to industry and research.


The current experiment builds on previous research led by Harvard engineer Daniel Nocera, who in 2011 demonstrated an "artificial leaf" device that uses solar power to generate usable energy. 

Nocera's original invention was a wafer-like electrode suspended in water. When a current runs through the electrode from a power source such as a solar panel, for example, it causes the water to break down into its two components: hydrogen and oxygen. 

Nocera's device garnered a lot of attention for opening up the possibility of using sunlight to create hydrogen fuel—once considered a possible alternative to gasoline. 

But hydrogen has not taken off as a fuel source, even as other alternative energy sources survive and grow amid historically low oil prices. Hydrogen is expensive to transport, and the costs of adopting and distributing hydrogen are high. A gas station owner could more easily switch a pump from gasoline to biofuel, for example.


Now, Nocera and a team of Harvard researchers figured out how to use the bionic leaf to make a burnable biofuel, according to a study published Monday in the journal PNAS. The biologists on the team genetically modified a strain of bacteria that consumes hydrogen and produces isopropanol—the active ingredient in rubbing alcohol. In doing so, they successfully mimicked the natural process of photosynthesis—the way plants use energy from the sun to survive and grow.

 This makes two things possible that have always been serious challenges for alternative energy space—solar energy can be converted into a storable form of energy, and the hydrogen can generate a more easily used fuel.
To be sure, the bionic leaf developments are highly unlikely to replace fossil fuels such as oil and natural gas any time soon—especially as the prices of both are currently so low. But it could be a good supplemental source. 

"One idea Dan [Nocera] and I share, which might seem a little wacky, is personalized energy" that doesn't rely on the power grid, biochemist Pamela Silver, who participated in the study, told CNBC in a telephone interview. 
Typically, people's energy needs are met by central energy production facilities—they get their electricity from the power grid, which is fed by coal- or gas-burning power plants, or solar farms, for example. Silver said locally produced energy could be feasible in developing countries that lack stable energy infrastructure, or could even appeal to people who choose to live off the grid.

"Instead of having to buy and store fuel, you can have your bucket of bacteria in your backyard," Silver said. 

Besides, the experiment was an attempt at proof-of-concept—the scientists wanted to demonstrate what could be done, Silver said. Now that they have mastered this process, further possibilities can be explored.  

 "No insult to chemists, but biology is the best chemist there is, so we don't even know what we can make," said Silver. "We can make drugs, materials—we are just at the tip of the iceberg." 

The team hopes to develop many different kinds of bacteria that can produce all sorts of substances. That would mean, potentially at least, setting up the bionic leaf device and then plugging in whatever kind of bacteria might be needed at the moment.

For now, they want to increase the efficiency of the device, which is already much more efficient at photosynthesizing than plants are. Then they will focus on developing other kinds of bacteria to plug into the device.

"The uber goal, which is probably 20 years out," Silver said, "is converting the commodity industry away from petroleum."

NASA’s Orion Conquers Orbital Test as U.S. Budget Debate Looms

December 6, 2014 / / 0 Comments




Excerpt from
businessweek.com

The Orion spacecraft’s almost flawless debut flight set the stage for the National Aeronautics and Space Administration’s next challenge: finding the funding to carry humans to Mars in the 2030s. 
The Apollo-like capsule orbited Earth twice yesterday to test critical functions, a 4 1/2-hour trip for the first U.S. vehicle built to transport humans to space since the shuttle in 1981. Now NASA must find political allies to keep championing a program that has already cost $7.4 billion. 

The voyage, less than two months after a pair of disasters stunned the commercial space industry, helps bolster NASA’s case for its biggest-ever expedition. Spending over 20 years for a Mars mission would dwarf outlays for the $100 billion International Space Station, the most expensive structure ever built.

“We have a new Congress in January -- let’s see what happens,” said Henry Hertzfeld, research professor of space policy and international affairs at George Washington University. At the very least, “anytime you have a success like that on something new, it’s great.” 

The NASA exploration budget that finances Orion and a new heavy-lift rocket is one of the few non-defense budget accounts for which House Republicans have proposed an increase from President Barack Obama’s request for fiscal 2015, said Brian Friel, a government fiscal analyst with Bloomberg Intelligence.

Spending Projections

Spending would rise 5 percent to $4.17 billion under the House bill, while the Senate proposes a 10 percent increase to $4.37 billion, according to data compiled by Bloomberg. The largest beneficiaries from more spending would be Lockheed Martin Corp. (LMT:US), which manufactured the Orion, and Boeing Co. (BA:US), the contractor’s co-owner of the venture building the new rocket.

Orion is the first spaceship developed to carry humans beyond the moon, and later versions will be fine-tuned to travel to asteroids next decade and to Mars in the 2030s. NASA is targeting an Orion trip with astronauts by 2021. 

While Orion was among the top trending topics worldwide on Twitter.com, NASA’s new ambitions are unfolding amid a federal budget squeeze and the short attention spans of the social-media era, not the race-for-the-moon competition of the Cold War. 

At Kennedy Space Center in Cape Canaveral, Florida, where a Delta IV Heavy rocket carried Orion aloft, some of the weather-worn buildings displayed faded signs from news organizations that once camped out to chronicle the Apollo program. They were a reminder that interest in NASA diminished after the U.S. won the race to the moon.
