Plants cut the mustard for basic discoveries in metabolism Posted: 05 Feb 2013 02:36 PM PST You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on the development of more productive plants and new therapies for metabolic diseases.

Steroids help reverse rapid bone loss tied to rib fractures Posted: 05 Feb 2013 02:36 PM PST A series of studies found that steroid drugs, known for inducing bone loss with prolonged use, actually help suppress a molecule that's key to the rapid bone loss process.

Alcohol mixed with diet drinks may increase intoxication more than alcohol and regular drinks Posted: 05 Feb 2013 01:25 PM PST A person's breath alcohol concentration (BrAC) after drinking is influenced by factors such as food. New findings show that mixing alcohol with a diet soft drink can result in a higher BrAC than mixing alcohol with a regular or sugar-sweetened drink. Individuals were unaware of these differences, which may pose safety risks such as drinking and driving.

Childhood emotional abuse dramatically strong among male alcohol-dependent individuals Posted: 05 Feb 2013 01:25 PM PST Alcohol dependent (AD) individuals have reduced central serotonergic neurotransmission. Childhood maltreatment can also have a negative impact on central serotonergic neurotransmission. A new study has found that self-reported childhood emotional abuse is associated with a 90-percent reduction in central serotonergic neurotransmission in male AD individuals.

Both heavy and incompatible drinking can increase the chances of divorce Posted: 05 Feb 2013 01:25 PM PST High levels of drinking have repeatedly been shown to predict divorce. A Norwegian study has examined the impact of both level of drinking and compatibility of drinking on divorce. Results indicate that: one, the more people drink, the higher the risk of divorce; and two, risk of divorce is lowered if the spouses drink approximately the same amount of alcohol.

Corticosteroid injection, physiotherapy do not provide significant improvement for 'tennis elbow' Posted: 05 Feb 2013 01:21 PM PST Among patients with chronic unilateral lateral epicondylalgia ("tennis elbow"), a single injection of corticosteroid medication was associated with poorer outcomes after one year and higher recurrence rates compared with placebo, while eight weeks of physiotherapy did not significantly improve long-term outcomes, according to a new study.

ACE inhibitor for PAD may improve pain-free walking Posted: 05 Feb 2013 01:21 PM PST Among patients with peripheral artery disease and intermittent claudication (pain in the calf that comes and goes, typically felt while walking), 24 weeks of treatment with the angiotensin-converting enzyme (ACE) inhibitor ramipril was associated with improvement in pain-free and maximum walking times and the physical health aspect of quality of life, according to a new study.

NASA's Deep Impact spacecraft eyes comet ISON Posted: 05 Feb 2013 01:04 PM PST NASA's Deep Impact spacecraft has acquired its first images of comet C/2012 S1 (ISON).

Samoan obesity epidemic starts at birth Posted: 05 Feb 2013 09:37 AM PST Born slightly heavy on average, a sample of hundreds of infants in American Samoa continued to gain weight quickly after birth, achieving high rates of obesity within 15 months. Breastfeeding slowed weight gain in boys. Findings may presage infant obesity in other populations where obesity is increasing population wide.

Giving transplanted cells a nanotech checkup Posted: 05 Feb 2013 09:37 AM PST Researchers have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies for conditions such as liver failure and type 1 diabetes. The study used nanoscale pH sensors and MRI machines to tell if liver cells injected into mice survived over time.

Mitochondrial mutations: When the cell's two genomes collide Posted: 05 Feb 2013 09:37 AM PST Plant and animal cells contain two genomes: One in the nucleus and one in the mitochondria. When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such illnesses, scientists have traced one example in fruit flies down to the individual errant nucleotides and the mechanism by which the flies become sick.

Old age offers no protection from obesity's death grip Posted: 05 Feb 2013 09:37 AM PST Obesity kills, giving rise to a host of fatal diseases. But when it comes to seniors, a slew of research has reported an "obesity paradox" that says, at age 65 and older, an elevated BMI won't shorten your lifespan, and may even extend it. A new study takes another look at the numbers, finding the earlier research flawed. The paradox was a mirage: As obese Americans grow older, in fact, their risk of death climbs.

Hubble catches the moment the lights went out Posted: 05 Feb 2013 09:37 AM PST The further away you look, the further back in time you see. Astronomers use this fact to study the evolution of the Universe by looking at nearby and more distant galaxies and comparing their features. Hubble is particularly well suited for this type of work because of its extremely high resolution and its position above the blurring effects of Earth's atmosphere. This has allowed it to detect many of the most distant galaxies known, as well as making detailed images of faraway objects.

A spiral galaxy with a secret Posted: 05 Feb 2013 09:37 AM PST The NASA/ESA Hubble Space Telescope -- with a little help from an amateur astronomer -- has produced one of the best views yet of nearby spiral galaxy Messier 106.

Fault lines in views on climate change revealed: Divided by cause, united by effect Posted: 05 Feb 2013 07:21 AM PST Climate change is a hotly debated issue, but a new study shows geoscientists and engineers also become embroiled in the issue -- and for some, it can get surprisingly personal. Younger, female engineers employed in government seemed to support the Kyoto Protocol, whereas their older, male counterparts -- largely employed by oil and gas companies -- tended to take a fatalistic response to climate change, labeling nature as the culprit.

New 'retention model' explains enigmatic ribbon at edge of solar system Posted: 05 Feb 2013 07:21 AM PST Since its Oct. 2008 launch, NASA's Interstellar Boundary Explorer has provided images of the invisible interactions between our home in the galaxy and interstellar space. Particles emanating from this boundary produce a striking, narrow ribbon, which had yet to be explained despite more than a dozen possible theories. In a new "retention model," researchers suggest that charged particles trapped in this region create the ribbon as they escape as neutral atoms.

Researchers spot attention deficits in babies who later develop autism Posted: 05 Feb 2013 07:21 AM PST Researchers are able to detect deficits in social attention in infants as young as six months of age who later develop Autism Spectrum Disorders. The results showed that these infants paid less attention to people and their activities than typically developing babies.

Stroke damage in mice overcome by training that 'rewires' brain centers Posted: 05 Feb 2013 07:21 AM PST Researchers have found that mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body, if the rodents are quickly subjected to physical conditioning that rapidly "rewires" a different part of the brain to take over lost function.

New molecular inhibitors hit difficult cancer target Posted: 05 Feb 2013 07:21 AM PST Early laboratory tests are the first to successfully use an experimental molecular therapy to block a hard-to-target part of a protein complex linked to several types of invasive cancer. Scientists report the rational design of a small-molecule inhibitor they call Y16. In laboratory tests, the inhibitor helped stop the spread of cultured human breast cancer cells, especially when it was used with another compound known as Rhosin/G04.
