Astronomers peer into the 'amniotic sac' of a planet-hosting star Posted: 13 Sep 2015 08:33 PM PDT Astronomers have successfully peered through the 'amniotic sac' of a star that is still forming to observe the innermost region of a burgeoning solar system for the first time.

Was Darwinius a little longer in the tooth than previously thought? Posted: 13 Sep 2015 09:32 AM PDT Darwinius shares more in common with modern lemurs based on how its teeth erupted, according to new model.

Achieving effective health care with a new approach to caring for chronic illnesses Posted: 11 Sep 2015 01:42 PM PDT Researchers address the challenges of effective universal health coverage in low- and middle-income countries, focusing on solving one of the most pressing issues: the care of chronic illnesses. Their suggestions, aimed at strengthening health care systems, include recommendations based on a 'diagonal approach' for managing health care.

Periodontitis and heart disease: Researchers connect the molecular dots Posted: 11 Sep 2015 01:42 PM PDT Periodontitis is a risk factor for heart disease. Now a team of researchers has shown that a periodontal pathogen causes changes in gene expression that boost inflammation and atherosclerosis in aortic smooth muscle cells.

'Lab-on-a-Chip' technology to cut costs of sophisticated tests for diseases and disorders Posted: 11 Sep 2015 01:41 PM PDT Engineers have developed a breakthrough device that can significantly reduce the cost of sophisticated lab tests for medical disorders and diseases, such as HIV, Lyme disease and syphilis. The new device uses miniaturized channels and valves to replace 'benchtop' assays -- tests that require large samples of blood or other fluids and expensive chemicals that lab technicians manually mix in trays of tubes or plastic plates with cup-like depressions.

Reducing liver fluke transmission in northeastern Thailand Posted: 11 Sep 2015 11:12 AM PDT A new model tested in northeastern Thailand shows that a multi-pronged approach -- combining treatment, ecosystem monitoring, and community mobilization -- can effectively tackle the transmission of liver flukes, according to research supported by the International Development Research Centre (IDRC).

High-efficiency, high-reliability perovskite solar cells realized by a low-temperature solution process Posted: 11 Sep 2015 11:12 AM PDT Researchers in Japan succeeded in producing highly reproducible and highly stable perovskite solar cells by a low-temperature solution process.

Optoelectronics: Tapering off for efficiency Posted: 11 Sep 2015 11:12 AM PDT A new compact structure enables efficient lasers to be realized on silicon chips.

Batteries: Power of marine inspiration Posted: 11 Sep 2015 11:12 AM PDT Bioinspired carbon anodes enable high performance in lithium-ion batteries.

Identification of atomic species at the surface of anatase titanium dioxide by scanning probe microscopy Posted: 11 Sep 2015 11:12 AM PDT A research team in Japan has successfully identified the atoms and common defects existing at the most stable surface of the anatase form of titanium dioxide by characterizing this material at the atomic scale with scanning probe microscopy.

Researchers to develop robotic device to help visually impaired Posted: 11 Sep 2015 11:11 AM PDT A project to build a wearable robotic device could help millions of visually impaired people.

A scalable and secure cloud computing infrastructure for Big Science Posted: 11 Sep 2015 11:10 AM PDT Researchers in Finland have developed a scalable and secure cloud computing infrastructure for CMS data analysis at CERN. The solution is a hybrid one combining the advantages and disadvantages of grid and cloud systems. The infrastructure is expected to support also other scientific applications.

Ebola virus mutations may help it evade drug treatment Posted: 11 Sep 2015 11:07 AM PDT Genetic mutations called 'escape variants' in the deadly Ebola virus appear to block the ability of antibody-based treatments to ward off infection, according scientists. Their findings have implications for the continued development of therapeutics to treat Ebola virus disease, which has claimed the lives of over 11,000 people in West Africa since last year.

Genetic mechanism for cancer progression discovered Posted: 11 Sep 2015 08:27 AM PDT Genetics researchers have identified a novel long non-coding RNA, dubbed DACOR1, that has the potential to stymie the growth of tumor cells in the second-most deadly form of cancer in the US -- colorectal cancer.

Best precision yet for neutrino measurements at Daya Bay Posted: 11 Sep 2015 08:10 AM PDT Physicists have announced new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment continues to be one to watch.

New research and development and manufacturing hub for high-tech glass Posted: 11 Sep 2015 06:55 AM PDT A research and development and manufacturing hub based on a new generation of specialty glass products for the global science and medical equipment market was announced at the University of Adelaide today.

Making a difference with open source science equipment Posted: 11 Sep 2015 06:55 AM PDT Science can be expensive. But making customized scientific equipment doesn't have to be. Researchers at Michigan Technological University have compiled economic data on the effectiveness of open source hardware in the laboratory -- and the process looks promising.

South Florida an attractive home for invading reptiles Posted: 11 Sep 2015 06:55 AM PDT South Florida is on the front lines in the war against invasive reptiles and amphibians because its warm climate makes it a place where they like to live, a new study shows. Using computer models and data showing where reptiles live in Florida, scientists predicted where they could find non-native species in the future. They found that as temperatures climb, areas grow more vulnerable to invasions by exotic reptiles. Conversely, they found that extreme cold temperatures protect against invasion.

Sedentary lifestyle and overweight weaken arterial health already in childhood Posted: 11 Sep 2015 06:51 AM PDT Arterial wall stiffness and reduced arterial dilation are the first signs of cardiovascular diseases that can be measured. A new study carried out in Finland shows that low levels of physical activity, weaker physical fitness and higher body fat content are linked to arterial stiffness already in 6-8 year-old children.

Down but not out: Inhibited Tyk2 retains anti-cancer activity Posted: 11 Sep 2015 06:51 AM PDT Tyrosine kinase 2 (Tyk2) is an enzyme involved in intracellular signalling and has an important role in activating the immune system. But enzymatically active Tyk2 can also promote excessive immune reactions and growth of certain cancer types.

Call for government to curb the production and sale of cheap salty junk food Posted: 11 Sep 2015 06:49 AM PDT A World Health Organization adviser is calling for the British government to stop food manufacturers and distributors producing and selling unhealthy, cheap, salty junk food.

Using magnetic permeability to store information Posted: 11 Sep 2015 06:49 AM PDT Scientists have made promising steps in developing a new magnetic memory technology, which is far less susceptible to corruption by magnetic fields or thermal exposure than conventional memory. The findings report the use of magnetic permeability -- how easily a magnetic field will magnetize a material.

Replicating liver cells for fast drug testing Posted: 11 Sep 2015 06:49 AM PDT Scientists have developed a new technique that produces a user friendly, low cost, tissue-engineered pseudo-organ. The chip-based model produces a faithful mimic of the in vivo liver inside a scalable fluid-handling device, demonstrating proof of principle for toxicology tests and opening up potential use in drug testing and personalized medicine.

More time for school lunches equals healthier choices for kids Posted: 11 Sep 2015 06:49 AM PDT Elementary and middle school students who are given at least 25 minutes to eat lunch are more likely to choose fruits and consume more of their entrees, milk, and vegetables according to a new study.
