Radiation before surgery more than doubles mesothelioma survival Posted: 20 Jan 2014 02:32 PM PST Results of clinical research that treated mesothelioma with radiation before surgery show the three-year survival rate more than doubled for study participants afflicted with this deadly disease, compared to treating with surgery first.

People who enjoy life maintain better physical function as they age Posted: 20 Jan 2014 09:14 AM PST People who enjoy life maintain better physical function in daily activities and keep up faster walking speeds as they age, compared with people who enjoy life less, according to a new study.

FAK helps tumor cells enter bloodstream Posted: 20 Jan 2014 09:14 AM PST Cancer cells have something that every prisoner longs for -— a master key that allows them to escape. A new study describes how a protein that promotes tumor growth also enables cancer cells to use this key and metastasize.

Deciphering plants' electrical signals to devise new environmental biosensors Posted: 20 Jan 2014 08:47 AM PST Science is becoming closer emulating the fiction of a popular Avatar movie, by deciphering plants' electrical signals to devise new holistic environmental biosensors.

Rosetta: 'Sleeping beauty' wakes up from deep space hibernation Posted: 20 Jan 2014 08:11 AM PST It was a fairy-tale ending to a tense chapter in the story of the Rosetta space mission this evening as the European Space Agency heard from its distant spacecraft for the first time in 31 months.

First infrared satellite monitoring of peak pollution episodes in China Posted: 20 Jan 2014 06:55 AM PST Plumes of several anthropogenic pollutants (especially particulate matter and carbon monoxide) located near ground level over China have for the first time been detected from space. The work was carried out using measurements by the infrared sounder launched on board the MetOp[3] satellite. These groundbreaking results represent a crucial step towards improved monitoring of regional pollution and forecasting of local pollution episodes, especially in China.

Smoking late in pregnancy reduces baby's birth weight Posted: 20 Jan 2014 06:55 AM PST A doctoral dissertation finds that every cigarette a mother smokes a day during the third quarter of pregnancy reduces the baby's birth weight in 20 grams.

Novel nanotherapy breakthrough may help reduce recurrent heart attacks, stroke Posted: 20 Jan 2014 06:55 AM PST A new report shows that new statin nanotherapy can target high-risk inflammation inside heart arteries that causes heart attacks or stroke.

Milky Way may have formed 'inside-out:' Gaia provides new insight into galactic evolution Posted: 20 Jan 2014 06:06 AM PST Research on first data release from Gaia-ESO project suggests the Milky Way formed by expanding out from the center, and reveals new insights into the way our Galaxy was assembled.

Ingredients in chocolate, tea, berries could guard against diabetes Posted: 20 Jan 2014 06:06 AM PST Eating high levels of flavonoids including anthocyanins and other compounds (found in berries, tea, and chocolate) could offer protection from type 2 diabetes -- according to research. The study of almost 2,000 people showed that high intakes of these dietary compounds are associated with lower insulin resistance and better blood glucose regulation.

Exposure to pesticides results in smaller worker bees Posted: 20 Jan 2014 06:06 AM PST Exposure to a widely used pesticide causes worker bumblebees to grow less and then hatch out at a smaller size, according to a new study.

Keeping whales safe in sound Posted: 20 Jan 2014 06:06 AM PST Global efforts are intensifying to safeguard whales and other marine species from the harms of powerful noise used in seismic seafloor surveys by the oil and gas industry and others. The impetus is the newly-documented success of harm mitigation measures used in a study near critical whale feeding grounds around energy resource-rich Sakhalin Island, Russia, just north of Japan.

Secondhand smoke exposure increases odds of hospital asthma readmission for children Posted: 20 Jan 2014 06:06 AM PST A new study shows that exposure to secondhand smoke at home or in the car dramatically increases the odds of children being readmitted to the hospital within a year of being admitted for asthma.

Frog fathers don't mind dropping off their tadpoles in cannibal-infested pools Posted: 20 Jan 2014 06:04 AM PST Given a choice, male dyeing poison frogs snub empty pools in favor of ones in which their tiny tadpoles have to grow in the company of larger, carnivorous ones of the same species. The frog fathers only choose to deposit their developing young in unoccupied pools when others are already filled with tadpoles of a similar size. These are seemingly counterintuitive decisions, given how often cannibalism involving a large tadpole eating a smaller one takes place in natural pools.

Ultra-thin tool heating for injection molding Posted: 20 Jan 2014 06:04 AM PST In future, thin-film heating will allow plastic parts to be produced with greatly improved surface quality. Researchers have also found a way to make the whole process more energy efficient.

Hydrocephalus: Sensors monitor cerebral pressure Posted: 20 Jan 2014 06:04 AM PST If the pressure in a patient's brain is too high, physicians implant a system in the head that regulates the pressure. A sensor can now measure and individually adjust brain pressure. The sensor system is approved for use as a long-term implant.

Childhood obesity can only be tackled with broad public health interventions Posted: 20 Jan 2014 06:04 AM PST Public health researchers have found single dietary interventions are not effective at increasing fruit and vegetable consumption among overweight children and will not halt the global epidemic in childhood obesity. The team says broader public health strategies are needed instead as obesity figures continue to rise.

Quality control of mitochondria as defense against disease Posted: 20 Jan 2014 06:04 AM PST Scientists have discovered that two genes linked to hereditary Parkinson's disease are involved in the early-stage quality control of mitochondria. The protective mechanism removes damaged proteins that arise from oxidative stress from mitochondria.

Forget about forgetting: Elderly know more, use it better Posted: 20 Jan 2014 06:04 AM PST What happens to our cognitive abilities as we age? If your think our brains go into a steady decline, research reported this week may make you think again. The work takes a critical look at the measures usually thought to show that our cognitive abilities decline across adulthood. Instead of finding evidence of decline, the team discovered that most standard cognitive measures, which date back to the early twentieth century, are flawed.

Melatonin may lower prostate cancer risk Posted: 20 Jan 2014 05:50 AM PST Higher levels of melatonin, a hormone involved in the sleep-wake cycle, may suggest decreased risk for developing advanced prostate cancer, according to results of new research.

Possible explanation for link between exercise, improved prostate cancer outcomes Posted: 20 Jan 2014 05:50 AM PST Men who walked at a fast pace prior to a prostate cancer diagnosis had more regularly shaped blood vessels in their prostate tumors compared with men who walked slowly, providing a potential explanation for why exercise is linked to improved outcomes for men with prostate cancer, according to research.

Peeking into Schrödinger's Box Posted: 20 Jan 2014 05:50 AM PST Until recently, measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones. Researchers have been able to apply a recently developed, alternative method called direct measurement to do this in a single experiment with no post-processing.

Researchers discover how heart arrhythmia occurs Posted: 19 Jan 2014 11:24 AM PST Researchers have discovered the fundamental biology of calcium waves in relation to heart arrhythmias.
