- Lichen can survive in space: Space station research sheds light on origin of life; potential for better sunscreens
- Is your leaf left-handed?
- Reward the second best, ignore the best
| Posted: 23 Jun 2012 11:56 AM PDT You can freeze it, thaw it, vacuum dry it and expose it to radiation, but still life survives. Research on the International Space Station is giving credibility to theories that life came from outer space -- as well as helping to create better sunscreens.  |
| Posted: 23 Jun 2012 06:43 AM PDT The spiral pattern of leaf formation from the point of growth affects the developing leaf's exposure to the plant hormone auxin; This exposure leads to measurable left-right asymmetry in leaf development, in species previously assumed to have symmetric leaves.  |
| Reward the second best, ignore the best Posted: 22 Jun 2012 01:35 PM PDT New research suggests reasons why the richest should pay more tax; why rewarding the top performers leads to recurrent crises and scandals; and why we should resist the temptation to learn from and imitate the most successful.  |

| Pasta made from green banana flour a tasty alternative for gluten-free diets Posted: 23 Jun 2012 11:51 AM PDT People with celiac disease struggle with limited food choices, as their condition makes them unable to tolerate gluten, found in wheat and other grains. Researchers have now developed a gluten-free pasta product from green banana flour, which tasters found more acceptable than regular whole wheat pasta. The product has less fat and is cheaper to produce than standard pastas.  |
| Posted: 23 Jun 2012 11:51 AM PDT The commonly-used epilepsy drug, valproic acid (VPA), can have a highly beneficial effect on some babies born with spinal muscular atrophy (SMA), the number one genetic killer during early infancy. But in about two-thirds of such cases it is either damaging or simply has no effect. Now, for the first time, researchers have found a way to identify which patients are likely to respond well to VPA prior to starting treatment. Their results have major implications, not just for SMA patients, but for other conditions treated with the drug such as migraine and epilepsy, and may even provide the conditions for turning VPA non-responders into responders, the researchers say.  |
| Is arm length the reason women need reading glasses sooner than men? Posted: 23 Jun 2012 11:49 AM PDT Studies have consistently reported that women require reading glasses or bifocal lenses earlier than men. According to a recent article, the gender difference is caused by factors other than focusing ability, such as arm length or preferred reading distance, which should be considered when prescribing readers or bifocals.  |
| Declining testosterone levels in men not part of normal aging Posted: 23 Jun 2012 11:49 AM PDT A new study finds that a drop in testosterone levels over time is more likely to result from a man's behavioral and health changes than by aging.  |
| Long-term testosterone treatment for men results in reduced weight and waist size Posted: 23 Jun 2012 11:49 AM PDT In testosterone-deficient men, major weight loss was an added benefit of testosterone replacement therapy for most of the patients who participated in a new study.  |
| Mild thyroid dysfunction in early pregnancy linked to serious complications Posted: 23 Jun 2012 11:49 AM PDT Even moderate thyroid dysfunction during early pregnancy significantly increases the risk of serious complications, underscoring the need for universal screening in the first trimester, a new study finds.  |
| Zebrafish research shows how dietary fat regulates cholesterol absorption Posted: 23 Jun 2012 06:44 AM PDT New research suggests there may be a biological reason why fatty and cholesterol-rich foods, like buttery shrimp, fried eggs and burgers and fries are so appealing together. Researchers are using zebrafish to better understand the cellular mechanisms of cholesterol processing and have discovered a surprising link between dietary fat and cholesterol absorption.  |
| Another reason why dads and hopeful dads should quit smoking now Posted: 23 Jun 2012 06:44 AM PDT If your father smoked, your genes are likely damaged, and your odds for diseases increased. A new report shows that men who smoke before conception can damage the genes of their offspring. These inherited changes in DNA could render developing offspring susceptible to later diseases, providing evidence for quitting smoking before trying to conceive.  |
| 'Trust' hormone oxytocin found at heart of rare genetic disorder Posted: 23 Jun 2012 06:44 AM PDT The hormone oxytocin -- often referred to as the "trust" hormone for its role in stimulating emotional responses -- plays an important role in Williams syndrome, according to a new study.  |
| Novel animal reservoir for group of tick-borne diseases discovered -- and it lives in your backyard Posted: 23 Jun 2012 06:44 AM PDT A new assay that uses mitochondrial DNA that mutates faster than nuclear DNA has allowed scientists to identify one of the major animal reservoirs for the ehlichioses, STARI and other tick-borne diseases in the southeastern United States. The animal turned out to be the eastern gray squirrel.  |
| Infection biology: The elusive third factor Posted: 22 Jun 2012 01:39 PM PDT Researchers have identified an enzyme that is involved in a modification pathway that is essential for bacterial pathogenicity. Because it shows no similarity to other known proteins, it may be an ideal target for development of novel antimicrobial drugs.  |
| Grb2 holds powerful molecular signaling pathway in check Posted: 22 Jun 2012 01:38 PM PDT Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists report.  |
| South African daffodils may be a future treatment for depression Posted: 22 Jun 2012 01:37 PM PDT Scientists have discovered that plant compounds from a South African flower may in time be used to treat diseases originating in the brain – including depression. A number of these substances have now been tested in a laboratory model of the blood-brain barrier.  |
| Information flow in the brain is not a 'one-way street' Posted: 22 Jun 2012 01:35 PM PDT Neuroscientists have discovered a new principle of information flow in nerve cells.  |
| New approach to diagnosing and treating dementia Posted: 22 Jun 2012 01:35 PM PDT Some dementia patients show symptoms of a malfunctioning immune system. New research shows that immune reactions against the body's own nerve cells can be the cause of advanced dementia and an appropriate immune suppressive therapy can develop with significant effectiveness.  |
| Most commonly mutated gene in cancer may have a role in stroke Posted: 22 Jun 2012 01:28 PM PDT The gene p53 is the most commonly mutated gene in cancer. p53 is dubbed the "guardian of the genome" because it blocks cells with damaged DNA from propagating and eventually becoming cancerous. However, new research uncovers a novel role for p53 beyond cancer in the development of ischemic stroke. The research team identified an unexpected critical function of p53 in activating necrosis, an irreversible form of tissue death, triggered during oxidative stress and ischemia.  |
| Parents' work-life stress hinders healthy eating Posted: 22 Jun 2012 01:28 PM PDT These days many parents are working harder than ever to support their families, and as a result, nutrition in the home suffers, according to a new study.  |
| Pregnant women should avoid alcohol during pregnancy, experts say Posted: 22 Jun 2012 01:28 PM PDT Experts disagree with a series of new studies from Denmark that suggest consumption of up to 8 alcoholic drinks a week or occasional binge drinking during pregnancy is generally safe for the developing baby.  |
| The biology of tumor-derived microvesicles Posted: 21 Jun 2012 04:59 PM PDT A new article discusses the biology of tumor-derived microvesicles and their clinical application as circulating biomarkers. Microvesicles are membrane-bound sacs released by tumor cells and can be detected in the body fluids of cancer patients.  |
| New evidence in fructose debate: Could it be healthy for us? Posted: 21 Jun 2012 04:57 PM PDT A new study suggests that fructose may not be as bad for us as previously thought and that it may even provide some benefit.  |
