Vitamin D significantly improves symptoms of winter-related atopic dermatitis in children Posted: 03 Oct 2014 10:54 AM PDT A study conducted in more than 100 Mongolian schoolchildren found that daily treatment with a vitamin D supplement significantly reduced the symptoms of winter-related atopic dermatitis, a type of eczema.

Moderate weekly alcohol intake linked to poorer sperm quality in healthy young men Posted: 02 Oct 2014 07:12 PM PDT Moderate alcohol intake of at least 5 units every week is linked to poorer sperm quality in otherwise healthy young men, suggests research. And the higher the weekly tally of units, the worse the sperm quality seems to be, the findings indicate, prompting the researchers to suggest that young men should be advised to steer clear of habitual drinking.

Strong working memory puts brakes on problematic drug use Posted: 02 Oct 2014 10:11 AM PDT Adolescents with strong working memory are better equipped to escape early drug experimentation without progressing into substance abuse issues, says a researcher. Most important in the picture is executive attention, a component of working memory that involves a person's ability to focus on a task and ignore distractions while processing relevant goal-oriented information, she says.

New technology isolates tumor cells from blood to optimize cancer therapy Posted: 02 Oct 2014 10:10 AM PDT Circulating tumor cells (CTCs) from breast cancer patients were isolated from blood and grown in the laboratory for extensive genetic analysis. Such analysis enabled the identification of the most effective cancer drug or drug combination for each patient's tumor -- a significant step towards "precision" cancer treatment.

MRSA biofilms in joint fluid make infections tough to tackle Posted: 02 Oct 2014 09:37 AM PDT Scientists come one step closer to understanding why joint infections are difficult to treat. Biofilms play a role. "Biofilm formation has been suspected to play a key role during septic arthritis and prosthetic joint infection." said one expert. "This study could help explain why these infections have been so difficult to treat and point to therapeutic approaches that could make antibiotics more effective."

Engineers use 3-D gaming gear to give eye-opening look at cells in action Posted: 03 Oct 2014 06:43 PM PDT For hundreds of years biologists have studied cells through the lens of a microscope. With a little help from a team of engineers, these scientists could soon be donning 3-D glasses in a home-theater-like lab to take their own fantastic voyage into the petri dish.

Fast, cheap nanomanufacturing: Tiny conical tips fabricate nanoscale devices cheaply Posted: 03 Oct 2014 10:54 AM PDT Scientists have developed dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and "smart" textiles; or propulsion systems for fist-sized "nanosatellites."

Fish colon offers insight into evolution Posted: 03 Oct 2014 10:51 AM PDT Skates have primitive colons. This may not sound like a big deal, but it is. The discovery could change scientific understanding of evolution, of how animals emerged from water to live on land.

In a bad mood? Head to Facebook and find someone worse off Posted: 02 Oct 2014 09:30 AM PDT When people are in a bad mood, they are more likely to actively search social networking sites like Facebook to find friends who are doing even worse than they are, a new study suggests. "One of the great appeals of social network sites is that they allow people to manage their moods by choosing who they want to compare themselves to," the authors said.

Beer from 1840 shipwreck: Scientists developing new taste sensations for beer lovers from old beer Posted: 02 Oct 2014 06:24 AM PDT Scientists are analyzing the bottles of beer salvaged from the 1840s shipwreck found near the Åland Islands in 2010. Living bacteria found in the bottles were subject to further tests to find out how the cells had survived for so long in the wreck.

NASA's SDO watches giant filament on the sun Posted: 03 Oct 2014 06:43 PM PDT A snaking, extended filament of solar material currently lies on the front of the sun -- some 1 million miles across from end to end. Filaments are clouds of solar material suspended above the sun by powerful magnetic forces. Though notoriously unstable, filaments can last for days or even weeks.

Engineers use 3-D gaming gear to give eye-opening look at cells in action Posted: 03 Oct 2014 06:43 PM PDT For hundreds of years biologists have studied cells through the lens of a microscope. With a little help from a team of engineers, these scientists could soon be donning 3-D glasses in a home-theater-like lab to take their own fantastic voyage into the petri dish.

Continuous fabrication system for highly aligned polymer films provides method for tuning mechanical and thermal properties in bulk polymers Posted: 03 Oct 2014 10:54 AM PDT Novel and scalable continuous fabrication process combining Couette flow extrusion and macroscopic plastic deformation results in ability to increase mechanical, thermal, and crystalline properties in bulk polymer films.

Breakthrough technique offers prospect of silicon detectors for telecommunications Posted: 03 Oct 2014 10:53 AM PDT Researchers have demonstrated a breakthrough technique that offers the first possibility of silicon detectors for telecommunications. For decades, silicon has been the foundation of the microelectronics revolution and, owing to its excellent optical properties in the near- and mid-infrared range, is now promising to have a similar impact on photonics.

Social networks can strengthen knowledge-sharing Posted: 03 Oct 2014 10:51 AM PDT Contrary to the notion that social networks are time-wasters, they could improve project management and the spread of specialized knowledge in the healthcare sector and possibly other large organizations, according to new research.

Nanotechnology: Fullerene spheres can be used to slide in the nanoworld Posted: 03 Oct 2014 06:21 AM PDT "Nano–machines" (around one billionth of a meter in size) of the future will need tiny devices to reduce friction and make movement possible. The C60 molecule, also known as fullerene or buckyball, seemed to many an excellent candidate for nano-bearings. Unfortunately, the results so far have been conflicting, calling for further studies, like the one just carried out by a theoretical team. Through a series of computer simulations the scientists uncovered the reason for the experimental discrepancies and shed light on the true potential of this material.
