Building a better weather forecast? SMAP may help Posted: 28 Jan 2015 03:56 PM PST If you were trying to forecast tomorrow's weather, you would probably look up at the sky rather than down at the ground. But if you live in the U.S. Midwest or someplace with a similar climate, one key to a better weather forecast may lie beneath your feet. Better soil moisture observations are just what the Soil Moisture Active Passive (SMAP) mission will provide. Scheduled for launch on Jan. 29, SMAP will collect the most accurate and highest-resolution soil moisture measurements ever made from a satellite SMAP will cover the entire globe in two to three days.

Cassini catches Saturn's moon Titan naked in the solar wind Posted: 28 Jan 2015 03:53 PM PST Researchers studying data from NASA's Cassini mission have observed that Saturn's largest moon, Titan, behaves much like Venus, Mars or a comet when exposed to the raw power of the solar wind. The observations suggest that unmagnetized bodies like Titan might interact with the solar wind in the same basic ways, regardless of their nature or distance from the sun.

Researchers produce two bio-fuels from a single algae Posted: 28 Jan 2015 02:01 PM PST A common algae commercially grown to make fish food holds promise as a source for both biodiesel and jet fuel, according to a new study.

Long-necked 'dragon' discovered in China: Dinosaur's lightweight neck spanned half the length of its body Posted: 28 Jan 2015 01:05 PM PST Paleontologists have discovered a new species of a long-necked dinosaur from a skeleton found in China. The new species belongs to a group of dinosaurs called mamenchisaurids, known for their extremely long necks sometimes measuring up to half the length of their bodies. Most sauropods, or long-necked dinosaurs, have necks only about one third the length of their bodies.

Some potentially habitable planets began as gaseous, Neptune-like worlds Posted: 28 Jan 2015 01:05 PM PST Two phenomena known to inhibit the potential habitability of planets -- tidal forces and vigorous stellar activity -- might instead help chances for life on certain planets orbiting low-mass stars, astronomers have found.

Engineer advances new daytime star tracker Posted: 28 Jan 2015 01:05 PM PST NASA is developing a precision attitude sensor or star tracker that would be able to locate points of reference, or in other words, stars, during daylight hours.

Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term Posted: 28 Jan 2015 01:05 PM PST Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change -- and rapid change -- at the world's northern reaches, according to a new paper.

Gully patterns document Martian climate cycles Posted: 28 Jan 2015 12:22 PM PST Gullies carved into impact craters on Mars provide a window into climate change on the Red Planet. A new analysis suggests Mars has undergone several ice ages in the last several million years. The driver of these climate swings is likely the Red Planet's wobbly axis tilt.

To reassure electric car buyers, combine battery leasing with better charging Posted: 28 Jan 2015 12:22 PM PST A proper choice of business model plays a critical role in electric vehicle industry where many consumers are subject to range and resale anxieties.

Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate change Posted: 28 Jan 2015 12:21 PM PST From the subarctic Pacific to the Chilean margins, extreme oxygen loss is stretching from the upper ocean to about 3,000 meters deep. In some oceanic regions, such loss occurred within 100 years or less, according to a new study.

Storm Chasers Take on Supercell Thunderstorms in Bangladesh Posted: 28 Jan 2015 12:21 PM PST This past April, Scott Olson touched down in Bangladesh to become the country's first known storm chaser. On the other side of the world, back in Oklahoma, meteorologists worked tirelessly to put together accurate forecasts to help Olson get into the thick of the country's notoriously elusive thunderstorms.

Why upper motor neurons degenerate in ALS Posted: 28 Jan 2015 11:19 AM PST Scientists have revealed a mechanism underlying the cellular degeneration of the upper motor neurons that die in ALS, and developed a model system that will allow further research on the degeneration.

Molecular alterations in head and neck cancers uncovered by study Posted: 28 Jan 2015 11:16 AM PST A new study shows genomic differences in head and neck cancers caused by infection with the human papillomavirus. In addition, researchers have uncovered new smoking-related cancer subtypes and potential new drug targets, and found numerous genomic similarities with other cancer types. Together, this study's findings may provide detailed explanations of how HPV infection and smoking play roles in head and neck cancer risk and disease development, and offer potential diagnostic and treatment directions.

Quantum computer as detector shows space is not squeezed Posted: 28 Jan 2015 11:16 AM PST Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions -- that it's not squeezed in one direction relative to another. A new experiment by physicists used partially entangled atoms -- identical to the qubits in a quantum computer -- to demonstrate more precisely than ever before that this is true: to one part in a billion billion.

Missing link in metal physics explains Earth's magnetic field Posted: 28 Jan 2015 11:16 AM PST Earth's magnetic field shields the life on our planet's surface from cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means it can easily conduct a flow of electrons. New findings show that a missing piece of the traditional theory explaining why metals become less conductive when they are heated was needed to complete the puzzle of this field-generating process.

Concentrating on word sounds helps reading instruction and intervention Posted: 28 Jan 2015 11:14 AM PST A neuroimaging study by psychologist suggests that phonics shouldn't be overlooked in favor of a whole-language technique, a finding that could help improve treatment and diagnosis of common reading disorders.

Damaged DNA may stall patrolling molecule to initiate repair Posted: 28 Jan 2015 11:14 AM PST Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. These finding suggest that the delay itself may be the key that allows the protein molecule to find its target, according to researchers.

Protein pathway involved in nicotine-induced lung cancer metastasis found Posted: 28 Jan 2015 11:14 AM PST Smoking is the leading cause of lung cancer, and it is estimated that more than 159,000 people in the United States died from the disease last year. Most of these deaths were because the cancer had spread to other organ sites. Following their recent discovery of a protein pathway, researchers are one step closer to understanding how lung cancer cells metastasize.

Earlier menopause linked to everyday chemical exposures Posted: 28 Jan 2015 11:14 AM PST Women whose bodies have high levels of chemicals found in plastics, personal-care products, common household items and the environment experience menopause two to four years earlier than women with lower levels of these chemicals, according to a new study.

Chimps with higher-ranking moms do better in fights Posted: 28 Jan 2015 10:13 AM PST For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of twelve years of observations of playground fights between young chimpanzees in East Africa finds that chimps with higher-ranked moms are more likely to win.

Playing with puzzles, blocks may build children's spatial skills Posted: 28 Jan 2015 10:13 AM PST Play may seem like fun and games, but new research shows that specific kinds of play are actually associated with development of particular cognitive skills. Data from an American nationally representative study show that children who play frequently with puzzles, blocks, and board games tend to have better spatial reasoning ability. Being able to reason about space, and how to manipulate objects in space, is a critical part of everyday life, helping us to navigate a busy street, put together a piece of furniture, even load the dishwasher. And these skills are especially important for success in particular academic and professional domains, including science, technology, engineering, and math (STEM).

Anthropology: Ancient skull from Galilee cave offers clues to the first modern Europeans Posted: 28 Jan 2015 10:13 AM PST The discovery of a 55,000-year-old partial skull in Northern Israel provides new insights into the migration of modern humans out of Africa. A key event in human evolution was the expansion of modern humans of African origin across Eurasia, replacing all other forms of hominin (humans and their predecessors), around 40,000-60,000 years ago. However, due to the scarcity of human fossils from this period, these ancestors of all present-day non-African modern populations have largely remained a mystery. Now, researchers describe a partial skull that dates to around 55,000, which was found at Manot Cave in Israel's Western Galilee.

Spiky 'hedgehog particles' for safer paints, fewer VOC emissions Posted: 28 Jan 2015 10:12 AM PST A new process that can sprout microscopic spikes on nearly any type of particle may lead to more environmentally friendly paints and a variety of other innovations.

What's happening with your donated specimen? Posted: 28 Jan 2015 09:54 AM PST When donating blood, plasma, human tissue or any other bodily sample for medical research, most people might not think about how it's being used. But if you were told, would you care? A new study indicates that most people are willing to donate just knowing that their contribution is going toward research. But, when specific scenarios are brought into the equation, that willingness changes.

Holes in valence bands of nanodiamonds discovered: Potential catalysts for splitting water Posted: 28 Jan 2015 09:54 AM PST Nanodiamonds are tiny crystals only a few nanometers in size. While they possess the crystalline structure of diamonds, their properties diverge considerably from those of their big brothers, because their surfaces play a dominant role in comparison to their extremely small volumes. Suspended in aqueous solutions, they could function as taxis for active substances in biomedical applications, for example, or be used as catalysts for splitting water.

New model for preserving donor tissue will allow more natural joint repair for patients Posted: 28 Jan 2015 09:54 AM PST Currently, doctors have to throw away more than 80 percent of donated tissue used for joint replacements because the tissue does not survive long enough to be transplanted. Now, researchers have developed a new technology that more than doubles the life of the tissue. This new technology was able to preserve tissue quality at the required level in all of the donated tissues studied, the researchers found.

Mobile apps take students into the laboratory Posted: 28 Jan 2015 09:54 AM PST Mobile apps have proved to be valuable educational tools, but laboratory instructors thus far have been limited to using mobile devices only for virtual laboratories with simulated experiments.

The two faces of Mars: Moon-sized celestial object crashed into south pole Posted: 28 Jan 2015 09:54 AM PST The two hemispheres of Mars are more different from any other planet in our solar system. Non-volcanic, flat lowlands characterize the northern hemisphere, while highlands punctuated by countless volcanoes extend across the southern hemisphere. Although theories and assumptions about the origin of this so-called and often-discussed Mars dichotomy abound, there are very few definitive answers. Geophysicists are now providing a new explanation.

Elucidating the origin of MDR tuberculosis strains Posted: 28 Jan 2015 09:53 AM PST A study has focused on the evolutionary history of the mycobacterium that causes tuberculosis, and more specifically on the Beijing lineage associated with the spread of multidrug resistant forms of the disease in Eurasia. While confirming the East-Asian origin of this lineage, the results also indicate that this bacterial population has experienced notable variations coinciding with key events in human history, scientists report.

Breakthrough in terahertz spectroscopy Posted: 28 Jan 2015 08:41 AM PST Although terahertz spectroscopy has great potential, especially for environmental monitoring and security screening applications, it previously could not be used effectively to study nanocrystals or molecules at extremely low concentrations. Scientists have now found a solution to this problem by increasing the technique's sensitivity using metallic nanostructures.

New protein detonates 'invincible' bacteria from within Posted: 28 Jan 2015 08:41 AM PST The epidemic of 'superbugs,' bacteria resistant to antibiotics, knows no borders -- presenting a clear and present danger around the globe. Now a groundbreaking discovery may strengthen efforts by the medical community to fight this looming superbug pandemic. By sequencing the DNA of bacteria resistant to viral toxins, researchers identified novel proteins capable of stymieing growth in treacherous antibiotic-resistant bacteria.

Did genetic links to modern maladies provide ancient benefits? Posted: 28 Jan 2015 08:40 AM PST Genetic variations associated with some modern maladies are extremely old, scientists have discovered, predating the evolution of Neanderthals, Denisovans (another ancient hominin) and contemporary humans.

Satellite study identifies water bodies important for biodiversity conservation Posted: 28 Jan 2015 06:35 AM PST Using satellite images to study changing patterns of surface water is a powerful tool for identifying conservationally important 'stepping stone' water bodies that could help aquatic species survive in a drying climate, a new study shows. The approach has been applied to the Swan Coastal Plain near Perth in Western Australia, which has more than 1,500 water bodies and is one of 25 designated biodiversity hotspots on the globe.

Researchers use sound to slow down, speed up, and block light Posted: 28 Jan 2015 06:35 AM PST How do you make an optical fiber transmit light only one way? Researchers have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed. This non-reciprocal behavior is essential for building isolators and circulators.

Children feel most positively about mothers who respect their autonomy Posted: 28 Jan 2015 06:35 AM PST Mothers who support their children's need for autonomy as the children grow tend to be viewed more positively by their children. The study included more than 2,000 mothers and their children. It measured maternal directiveness -- or the extent to which mothers controlled activities -- in play when children were 2 years old and then during a discussion about areas of disagreement when the children were in the fifth grade. Mothers' tendencies to display controlling behaviors predicted the extent to which the children viewed their mothers positively or negatively when the children were in fifth grade.

'Healthy' fat tissue could be key to reversing type 2 diabetes Posted: 28 Jan 2015 06:35 AM PST Preventing inflammation in obese fat tissue may hold the key to preventing or even reversing type 2 diabetes, new research has found.
