New marker, new target in Ewing's sarcoma Posted: 29 Jun 2012 06:19 PM PDT A new study implicates the protein EYA3 in Ewing's sarcoma chemoresistance. Checking level could help offer accurate prognosis and aid in treatment decisions, and could eventually provide a therapeutic target.

NASA explains why clocks will get an extra second on June 30 Posted: 29 Jun 2012 06:19 PM PDT If the day seems a little longer than usual on Saturday, June 30, 2012, that's because it will be. An extra second, or "leap" second, will be added at midnight to account for the fact that it is taking Earth longer and longer to complete one full turn--a day--or, technically, a solar day.

First successful 'spoofing' of unmanned aerial vehicles Posted: 29 Jun 2012 06:18 PM PDT Scientists demonstrated for the first time that the GPS signals of an unmanned aerial vehicle (UAV), or drone, can be commandeered by an outside source -- a discovery that could factor heavily into the implementation of a new federal mandate to allow thousands of civilian drones into the US airspace by 2015.

Skin contact breast tumor detection Posted: 29 Jun 2012 06:18 PM PDT A simple and cost effective imaging device for breast tumor detection based on a flexible and wearable antenna system has been developed. Researchers point out that their system holds the promise of much earlier detection than mammography.

Short stretches of piRNA evaluate cells' genetic history Posted: 29 Jun 2012 06:17 PM PDT A new study suggests that abundant small RNA molecules known as Piwi-interacting RNAs may be part of the cell's search engine, capable of querying the entire history of a cell's genetic past to detect the genes of foreign invaders.

Accelerated radiation effective for noninvasive breast cancer: Cut treatment time in half, study suggests Posted: 29 Jun 2012 06:15 PM PDT Accelerated whole breast irradiation after lumpectomy is an effective treatment for ductal carcinoma in situ (DCIS), a very common early stage and noninvasive form of breast cancer, meaning many more breast cancer patients could see their treatment times reduced by half, according to a new study.

New technique controls graphite to graphene transition Posted: 29 Jun 2012 06:15 PM PDT Physicists have found a way to systematically study and control the transition of graphite, the "lead" found in pencils, to graphene, one of the strongest, lightest and most conductive materials known.

Skipping breakfast can lead to unhealthy habits all day long Posted: 29 Jun 2012 11:30 AM PDT Compared to breakfast-eaters, breakfast-skippers tend to weigh more and have other unhealthy habits, such as consuming too many sugary drinks or high-calorie snacks, experts say

FOXO1 gene may play important role in Parkinson's disease Posted: 29 Jun 2012 11:26 AM PDT A recent study revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

Bangladeshi women prefer pollution-causing cookstoves Posted: 29 Jun 2012 11:25 AM PDT Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones despite significant health risks, according to a new study.

New technique could reduce number of animals needed to test chemical safety Posted: 29 Jun 2012 11:25 AM PDT A new way of testing the safety of natural and synthetic chemicals has been developed. The new research could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.

Britain's urban rivers bounce back Posted: 29 Jun 2012 11:25 AM PDT After decades of pollution, typically from poorly treated sewage and industrial waste, rivers in or near Britain's major urban areas are regaining insects such as mayflies and stoneflies that are typical of fast-flowing, oxygen-rich waters.

Cloud computing: Same weakness found in seven cloud storage services Posted: 29 Jun 2012 11:24 AM PDT Cloud storage services allow registration using false e-mail addresses – experts see the possibility for espionage and malware distribution.

Oldest Neolithic bow discovered in Europe Posted: 29 Jun 2012 11:24 AM PDT Researchers have discovered the oldest Neolithic bow in Europe at La Draga Neolithic site in Banyoles. The complete bow measures 108 cm long and was constructed of yew wood.

A slow trek towards starvation: Scott's polar tragedy revisited Posted: 29 Jun 2012 09:04 AM PDT On the centenary of Scott's ill-fated Terra Nova expedition to the South Pole, a new study has shown that Scott's men starved to death because they were consuming far too few calories to fuel their daily exertion.

EU's carbon allocation scheme and Scandinavia's carbon taxes have not reduced greenhouse gas emissions Posted: 29 Jun 2012 09:03 AM PDT The European Union implemented a cap and trade scheme in 2005 to help it fulfil its obligations under the first phase of the Kyoto Protocol for reducing carbon emissions. The Scandinavian nations had independently imposed a carbon tax in the 1990s as part of their effort to reduce carbon emissions. US researchers have tracked the carbon disclosures from both regions of Europe and found that neither the EU's carbon allocation scheme nor Scandinavia's carbon taxes have made any significant impact on reducing greenhouse gas emissions.

Help for cardiac arrest patients -- fast and without electricity Posted: 29 Jun 2012 09:03 AM PDT Textile cooling pads are to be used in future to prevent neurological damage after successful resuscitation. The system requires no electric power, making it ideal especially for first aid in case of cardiac arrest.

Meat-like vegetarian fare: Replicating the nutrition, texture and taste of meat and eggs Posted: 28 Jun 2012 09:53 PM PDT Food scientists are working to replicate the nutrition, as well as the texture, taste and functionalities of meat and eggs, by utilizing plant-based products and in-vitro technologies, according to new research.
