From Live Science:

A new series of NASA images illustrates how Earth's plant growth has changed over the past 11 years.

The images are part of the series, "World of Change: Global Biosphere." They show the yearly changes in plant growth between 1999 and 2008 based on data on chlorophyll on the ocean's surface and vegetation density on land. Scientists use the images to study Earth's carbon cycle – the uptake and release of carbon by Earth's biosphere.

The global biosphere, or the sum of all ecosystems that support life on Earth, is in constant flux. The images show changes in chlorophyll, the green pigment in plants allows photosynthesis to occur, averaged over each year. Changes in land growth are shown as a vegetation index, a blend of the variation between the summer flourishes and the slow growth winter.

From New Science:

A HOTEL bar in Arlington, Virginia, 23 October 2008. A group of computer security experts has spent the day holed up with law enforcement agencies. It is an annual event that attracts the best in the business, but one the participants like to keep low-key - and under the radar of the cybercriminals they are discussing.

That evening, conversation over drinks turned to a security update Microsoft had just released. Its timing was suspicious: updates usually came once a month, and the next was not due for two weeks. "I remember thinking I should take a look at this," recalls Paul Ferguson, a researcher at Trend Micro, a web security company in Cupertino, California.

Large Hadron Collider To Start Again, But Costs Rise In Race To Discover 'God Particle'

From The Telegraph:

The Large Hadron Collider is to be run flat out throughout the year in order to make up for lost time and to beat an American rival to finding the elusive Higgs Boson – known as the "God Particle".

The £4bn particle accelerator, which broke down last year, was to be turned off in winter to reduce energy demands during peak electricity prices.

But the delays and the news that a smaller less powerful accelerator at Fermilab in Illinois is closing in on the particle has meant it will continue running throughout the year – at an extra cost of £13 million.

Launching Saturday: Shuttle Endeavour Headed For Space Station

Space Shuttle Endeavour landing

From Yahoo News/Space.com:

CAPE CANAVERAL, Fla. - Seven astronauts are set to blast off on the space shuttle Endeavour Saturday morning on an ambitious mission bound for the International Space Station.

The shuttle is scheduled to lift off at 7:17 a.m. EDT (1117 GMT) from the seaside Launch Pad 39A here at NASA's Kennedy Space Center. Endeavour is slated for a grueling 16-day mission to ferry the final element of the space station's Japanese-built Kibo laboratory.

"We all realize that we have a tremendous amount of work to do," said Endeavour commander Mark Polansky. "We do know it's a combination of a sprint and a marathon, because it's a long, long mission."

Wired Science News for Your Neurons Scientists Create a Form of Pre-Life

From Wired Science:

A self-assembling molecule synthesized in a laboratory may resemble the earliest form of information-carrying biological material, a transitional stage between lifeless chemicals and the complex genetic architectures of life.

Called tPNA, short for thioester peptide nucleic acids, the molecules spontaneously mimic the shape of DNA and RNA when mixed together. Left on their own, they gather in shape-shifting strands that morph into stable configurations.

The molecules haven’t yet achieved self-replication, the ultimate benchmark of life, but they hint at it. Best of all, their activities require no enzymes — molecules that facilitate chemical reactions, but didn’t yet exist in the primordial world modeled by scientists seeking insight into life’s murky origins.

Fact or Fiction: Dogs Can Talk

From Scientific American:

Are human speech-like vocalizations made by some mammals equivalent to conversation--or just a rough estimation of it?

Maya, a noisy, seven-year-old pooch, looks straight at me. And with just a little prompting from her owner says, "I love you." Actually, she says "Ahh rooo uuu!"

Maya is working hard to produce what sounds like real speech. "She makes these sounds that really, really sound like words to everyone who hears her, but I think you have to believe," says her owner, Judy Brookes.

Antibody Drugs Customized by Genotype

From Technology Review:

A company wants to improve monoclonal-antibody therapies by tailoring them to patients' genotypes.

Monoclonal antibodies, which are engineered to hone in on very specific biological targets, have taken off therapeutically in recent years: several are now approved for treating cancers and autoimmune diseases, and nearly 200 are in clinical trials. But one of the challenges of monoclonal-antibody therapy is the fact that some people respond very well to the drugs while others respond only moderately or not at all.

A startup called PIKAMAB, based in Menlo Park, CA, believes that it can make monoclonal antibodies more effective by grouping patients together based on their genotype and offering a customized antibody developed for that genotype. The company hopes that this "stratified" approach to drug development and treatment will help drug companies achieve better results.

Health Risks Of Nanotechnology: How Nanoparticles Can Cause Lung Damage, And How The Damage Can Be Blocked

From Science Daily:

ScienceDaily (June 11, 2009) — Scientists have identified for the first time a mechanism by which nanoparticles cause lung damage and have demonstrated that it can be combated by blocking the process involved, taking a step toward addressing the growing concerns over the safety of nanotechnology.

Nanotechnology, the science of the extremely tiny (one nanometre is one-billionth of a metre), is an important emerging industry with a projected annual market of around one trillion US dollars by 2015. It involves the control of atoms and molecules to create new materials with a variety of useful functions, including many that could be exceptionally beneficial in medicine. However, concerns are growing that it may have toxic effects, particularly damage to the lungs. Although nanoparticles have been linked to lung damage, it has not been clear how they cause it.

The Great Shampoo Sham

You don't need to shampoo daily. And the "no poo" movement suggests you don't do it at all. But if not washing your hair sounds flat-out gross, and yet you want to avoid some iffy chemicals, there are many all-natural shampoos. Image credit: stockxpert

From Live Science:

Shampooing can be complicated. First, there are the convoluted instructions: Lather, rinse, repeat. It doesn't say anything about stopping. And now there's a movement afoot, called the "no poo" movement, advocating no shampooing whatsoever.

Shampoo is indeed a modern invention, as the no-poo'ers attest, developed roughly around the end of the 19th century. And few of us need to be shampooing every day, dermatologists say. That said, the necessity for shampoo varies from person to person, depending on your hair type and what you put in to your hair each day.

Forgoing shampooing completely, if that concept even appeals to you, ultimately could be rough on your hair and rougher on your social interactions.

From The National Geographic:

One of the largest known stars in the universe is shrinking rapidly, and astronomers don't know why.

Betelgeuse (pronounced almost like "beetle juice") is a red supergiant star 600 light-years away in the constellation Orion. From Earth the star is clearly visible with the naked eye as the reddish dot that marks Orion's left shoulder.

Researchers at the University of California, Berkeley, first measured the star in 1993 with an infrared instrument on top of Southern California's Mount Wilson. They estimated the star to be as big around as Jupiter's orbit around the sun.

From Yahoo News/Reuters:

BERLIN (Reuters) – A new, superheavy chemical element numbered 112 will soon be officially included in the periodic table, German researchers said.

A team in the southwest German city of Darmstadt first produced 112 in 1996 by firing charged zinc atoms through a 120-meter-long particle accelerator to hit a lead target.

"The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table," the scientists at the GSI Helmholtz Center for Heavy Ion Research said in a statement late on Wednesday.

The zinc and lead nuclei were fused to form the nucleus of the new element, also known as Ununbium, Latin for 112.

Larks and Owls: How Sleep Habits Affect Grades

Image Source / Corbis

From Time:

There are at least a few in every college dorm: students who seem to exist in their own time zone, in bed hours before everyone else and awake again at daybreak, rested and prepared for the morning's first lecture.

Sleep researchers refer to these early risers as larks (midnight-oil-burners are known as owls), and new data presented this week at the annual Associated Professional Sleep Societies suggest that a student's preferred sleeping schedule has a lot to do with his or her grade-point average in school. In one study, psychologists at Hendrix College in Arkansas found that college freshmen who kept night-owl hours had lower GPAs than early birds. Another group at the University of Pittsburgh revealed that poor sleep habits among high-schoolers led to lower grades, particularly in math.

Long Shot: Planet Could Hit Earth In Distant Future

From Yahoo News/Space.com:

Our solar system has a potentially violent future. New computer simulations reveal a slight chance that a disruption of planetary orbits could lead to a collision of Earth with Mercury, Mars or Venus in the next few billion years.

Despite its diminutive size, Mercury poses the greatest risk to the solar system's order. Results of the computer model show a roughly 1 percent chance that the elongation of Mercury's orbit will increase to the point where the planet's path around the sun crosses that of Venus. That's when planetary pandemonium would ensue, the researchers find, and Mercury could be ejected from the solar system, or collide with the sun or a neighboring planet, such as Earth.
