With atmospheric carbon dioxide passing the 400 parts-per-million milestone this year, the findings offer hope that wetlands could help soften the blow of climate change.

Heart of space weather observed in action Posted: 15 Jul 2013 01:49 PM PDT Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun, such as solar flares and coronal mass ejections, which can fling radiation and particles across the solar system.

New insights on cancer cell signaling Posted: 15 Jul 2013 01:49 PM PDT A pair of studies sheds light on a biological process which is activated across a vast range of malignancies.

Scientists outline long-term sea-level rise in response to warming of planet Posted: 15 Jul 2013 01:48 PM PDT A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms. This is one of the first analyses to combine four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes.

Drought response identified in potential biofuel plant Posted: 15 Jul 2013 01:48 PM PDT Drought resistance is the key to large-scale production of Jatropha, a potential biofuel plant -- and an international group of scientists has identified the first step toward engineering a hardier variety.

Fear factor: Missing brain enzyme leads to abnormal levels of fear in mice, new research reveals Posted: 15 Jul 2013 01:48 PM PDT A little bit of learned fear is a good thing, keeping us from making risky, stupid decisions or falling over and over again into the same trap. But new research from neuroscientists and molecular biologists shows that a missing brain protein may be the culprit in cases of severe over-worry, where the fear perseveres even when there's nothing of which to be afraid.

Elevated blood pressure increasing among children, adolescents Posted: 15 Jul 2013 01:47 PM PDT The risk of elevated blood pressure among children and adolescents rose 27 percent during a 13-year period, according to new research. Higher body mass, larger waistlines and eating excess sodium may be the reasons for the elevated blood pressure readings, researchers said.

Chinese people may be at higher risk for stroke than Caucasians Posted: 15 Jul 2013 01:47 PM PDT A new study suggests that Chinese people may be at higher risk for stroke than Caucasians.

Common autism supplement affects endocrine system Posted: 15 Jul 2013 12:11 PM PDT Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements. But a new study shows that may not be the case. Flavonoids tested in the study affected the endocrine system in ways that in one case promoted cancer and in another repressed it.

Chemical compound shows promise as alternative to opioid pain relievers Posted: 15 Jul 2013 12:11 PM PDT A drug targeting a protein complex containing two different types of opioid receptors may be an effective alternative to morphine and other opioid pain medications, without any of the side effects or risk of dependence, according to new research.

CSI-style DNA fingerprinting tracks down cause of cancer spread Posted: 15 Jul 2013 12:11 PM PDT How do stationary cancer cells get the mutations that allow them to travel through the body to seed metastasis? Do they just grow these mutations themselves? Study shows that cancer cells fuse with blood cells -- which already can travel! -- to create a hybrid, metastatic cancer cell.

Bilingual children have a two-tracked mind Posted: 15 Jul 2013 12:11 PM PDT Scientists have discovered insights that indicate children can learn two native languages as easily as they can learn one.

Comprehensive list of gene variants developed for cancer cells from nine tissue types Posted: 15 Jul 2013 12:11 PM PDT Scientists have developed a comprehensive list of genetic variants for each of the types of cells that comprise what is known as the NCI-60 cell line collection. This new list adds depth to the most frequently studied human tumor cell lines in cancer research, molecular pharmacology, and drug discovery.

Computer as smart as a 4-year-old? Researchers IQ test new artificial intelligence system Posted: 15 Jul 2013 12:10 PM PDT Artificial and natural knowledge researchers IQ-tested one of the best available artificial intelligence systems and learned that it's about as smart as the average 4-year-old.

Fiji's largest marine reserve swarming with sharks Posted: 15 Jul 2013 12:10 PM PDT Researchers have found that Fiji's largest marine reserve contains more sharks than surrounding areas that allow fishing, evidence that marine protected areas can be good for sharks.

In children with fever, researchers distinguish bacterial from viral infections Posted: 15 Jul 2013 12:10 PM PDT Many children develop fevers without an obvious cause. Now, researchers have shown they can tell whether a child has a viral or bacterial infection by profiling the activity of genes in a blood sample.

Scientists construct visual of intracellular 'zip code' signaling linked to learning, memory Posted: 15 Jul 2013 11:18 AM PDT New research provides a rare "picture" of the activity taking place at the single molecular level: visual evidence of the mechanisms involved when a cell transports mRNA (or messenger RNA) to where a protein is needed to perform a cellular function.

Nesting Gulf of Mexico loggerhead turtles face offshore risks Posted: 15 Jul 2013 11:18 AM PDT Threatened loggerhead sea turtles in the northern Gulf of Mexico can travel distances up to several hundred miles and visit offshore habitats between nesting events in a single season, taking them through waters impacted by oil and fishing industries.

Lunar cycle affects cardiac patients undergoing acute aortic dissection: Waning and full moon cycles impact length of stay, mortality Posted: 15 Jul 2013 11:18 AM PDT If you need cardiac surgery in the future, aortic dissection in particular, reach for the moon. Or at least try to schedule your surgery around its cycle. A new study found that acute aortic dissection repair performed in the waning full moon appears to reduce the odds of death, and a full moon was associated with shorter length of stay.

Distorted GPS signals reveal hurricane wind speeds Posted: 15 Jul 2013 10:56 AM PDT Researchers have found a way to do something completely different with GPS: Measure and map the wind speeds of hurricanes. The new technique could help meteorologists better predict storm severity, how storms form, and where they might be headed.

Chew more to retain more energy Posted: 15 Jul 2013 10:46 AM PDT Almonds may still be considered one of the highest energy food sources but it's not about how much you bite off, instead it's about how much you chew, according to new research.

Spicing up food can make up for missing fat Posted: 15 Jul 2013 10:46 AM PDT Adding just a small amount of everyday herbs and spices to vegetables and reduced-calorie meals may make those foods more appetizing to consumers, which could ultimately help Americans cut down on dietary fat and choose more foods in line with the Dietary Guidelines for Americans.

Attractive and successful: In bonobos, attractive females are more likely to win conflicts against males Posted: 15 Jul 2013 07:52 AM PDT While intersexual dominance relations in bonobos never have been thoroughly studied in the wild, several ideas exist of how females attain their dominance status. Some researchers suggest that bonobo female dominance is facilitated by females forming coalitions which suppress male aggression. Others think of an evolutionary scenario in which females prefer non-aggressive males which renders male aggressiveness to a non-adaptive trait.

Path of plaque buildup in brain shows promise as early biomarker for Alzheimer's disease Posted: 15 Jul 2013 07:51 AM PDT The trajectory of amyloid plaque buildup —- clumps of abnormal proteins in the brain linked to Alzheimer's disease —- may serve as a more powerful biomarker for early detection of cognitive decline rather than using the total amount to gauge risk, researchers suggest in a new study.

Neural origins of hot flashes identified in menopausal women Posted: 15 Jul 2013 07:51 AM PDT A new study from neuroscientists provides the first novel insights into the neural origins of hot flashes in menopausal women in years.
