Geologic maps of Vesta asteroid from NASA's Dawn mission Posted: 18 Nov 2014 11:45 AM PST Images from NASA's Dawn Mission have been used to create a series of high-resolution geological maps of the large asteroid Vesta, revealing the variety of surface features in unprecedented detail.

Field-emission plug-and-play solution for microwave electron guns Posted: 18 Nov 2014 11:16 AM PST On a quest to design an alternative to the two complex approaches currently used to produce electrons within microwave electron guns, a team of researchers has demonstrated a plug-and-play solution capable of operating in this high-electric-field environment with a high-quality electron beam.

Two sensors in one: Nanoparticles that enable both MRI and fluorescent imaging could monitor cancer, other diseases Posted: 18 Nov 2014 09:56 AM PST Chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging and fluorescent imaging in animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor's environment, or determine whether drugs have successfully reached their targets.

Car crash survival rates increase with being younger, male and driving a big vehicle Posted: 18 Nov 2014 09:55 AM PST Vehicle inequities have a significant impact on survivability in head-on collisions, a study by a doctoral student in epidemiology shows. Motor vehicle crashes are the most common cause of unintentional life lost around the world, with about 30,000 deaths occurring annually in the U.S. due to motor-vehicle crashes.

Facebook games may actually do some good in your life Posted: 18 Nov 2014 09:55 AM PST Beyond being a fun distraction, social network games can offer family members a meaningful way to interact and meet social obligations, a new study concludes. Researchers found that some online games offer families a common topic of conversation and enhance the quality of time spent together, despite the fact that most don't necessarily involve any direct communication. The games can also bring together family members who may be only distantly connected, with respondents citing experiences such as connecting with long-lost cousins or bolstering relationships with aging aunts.

Using science to open way to 'blue economy' Posted: 18 Nov 2014 09:54 AM PST New science and software make Belize coastal zone management plan better for people and the environment. With historic expansion of coastal and ocean development, ecosystems like coral reefs and mangrove forests are put at unprecedented risk. Yet, planners often lack good information about how human activities will impact shoreline and ocean habitats now and in the future. This study developed the information the Belizean government sought to make informed management decisions.

New model clarifies photoexcited thin-film lattice dynamics Posted: 18 Nov 2014 09:51 AM PST A research team has developed an analytical model to describe the structural dynamics of photoexcited thin films and verified it by ultrafast X-ray diffraction.

Better micro-actuators to transport materials in liquids Posted: 18 Nov 2014 07:59 AM PST Researchers have developed improved forms of tiny magnetic actuators thanks to new materials and a microscopic 3-D printing technology.

Physicists suggest new way to detect dark matter Posted: 18 Nov 2014 07:56 AM PST For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? Now physicists propose a new technique to detect dark matter.

Finding new ways to make drugs Posted: 18 Nov 2014 07:54 AM PST Chemists have developed a revolutionary new way to manufacture natural chemicals by clipping smaller molecules together like Lego. They have used the new method to assemble a scarce anti-inflammatory drug with potential to treat cancer and malaria, pseudopterosin.

Using sewage sludge to obtain bioenergy Posted: 18 Nov 2014 06:16 AM PST Researchers have found a way to increase biomass production by using sewage sludge as energy crop fertilizers. The usage of sewage sludge to fertilize energy crops could be an opportunity to release residues since these plantations are not intended for food industry.

US radiology departments prepare for Ebola Posted: 18 Nov 2014 04:29 AM PST Radiologists have issued a special report on radiology preparedness for handling cases of Ebola virus. Healthcare administrators are placing a major emphasis on Ebola preparedness training at medical facilities throughout the U.S. Failure to have proper procedures in place to diagnose and treat patients with Ebola virus was cited as a major reason for infection of medical personnel in Dallas.

Fundamental constants are still constant: Atomic clocks prove stability of mass ratio of protons to electrons Posted: 18 Nov 2014 04:27 AM PST Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a maximum of one part in a million over the age of our solar system (i.e. extrapolated over approx. 5 billion years). Previously, scientists deemed the possible changes to be twice as high. To obtain this result, physicists from PTB compared caesium and ytterbium atomic clocks with each other for 7 years.

Gravity may have saved the universe after the Big Bang, say researchers Posted: 18 Nov 2014 04:27 AM PST Physicists may now be able to explain why the universe did not collapse immediately after the Big Bang. Studies of the Higgs particle -- discovered at CERN in 2012 and responsible for giving mass to all particles -- have suggested that the production of Higgs particles during the accelerating expansion of the very early universe (inflation) should have led to instability and collapse.

Recycling Styrofoam into rigid plastic Posted: 18 Nov 2014 04:26 AM PST Mexican entrepreneurs designed the first national machine capable of recycling Styrofoam (expanded polystyrene) and transform it into a raw material used in the manufacture of transparent hard plastic.

Physicians prescribe less brand name drugs when electronic health record default settings show generics first Posted: 17 Nov 2014 02:43 PM PST Programming electronic health records to make generic drugs the default choice when physicians write prescriptions may offer one way to reduce unnecessary spending and improve health care value in the face of spiraling U.S. health expenditures, according to a new study.

Symmetrical knees linked to jamaican sprinting prowess Posted: 17 Nov 2014 01:44 PM PST Why is tiny Jamaica home to so many elite sprinters? One researcher thinks it may all be in the knees. For their study, the researchers measured the knees of 74 elite Jamaican sprinters and a control group of 116 non-sprinting Jamaicans of the same age and sex and similar in size and weight. They discovered that the sprinters' knees were much more symmetrical than the knees of people in the control group.

Method to measure residual stress in 3-D printed metal parts Posted: 17 Nov 2014 12:47 PM PST Researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing.

Recommendations by other customers significantly influence Internet purchasing behavior Posted: 17 Nov 2014 10:24 AM PST The online purchasing behavior of private individuals shopping in their leisure time is heavily influenced by recommendations made by other customers. Customer endorsements, in the form of Facebook 'Likes' for example, have a particularly marked influence on online buying behavior when consumers shop in the afternoon, evening, or at the weekend. There are certain economic theories concerning consumer attitudes to purchasing that, in the view of the researchers, can help explain this phenomenon.

Worldwide ship traffic up 300 percent since 1992 Posted: 17 Nov 2014 10:08 AM PST Maritime traffic on the world's oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. The research used satellite data to estimate the number of vessels on the ocean every year between 1992 and 2012. The number of ships traversing the oceans grew by 60 percent between 1992 and 2002. Shipping traffic grew even faster during the second decade of the study, peaking at rate of increase of 10 percent per year in 2011.

New image for 'big data' tools Posted: 14 Nov 2014 09:45 AM PST Big data represents both an opportunity and a challenge for scientists. The huge amount of data that can be generated by the latest scientific instruments could lead to important scientific discoveries, but only if scientists can efficiently process that data. This is especially true for analytical scientists studying biological materials using a fairly new technique known as mass spectrometry imaging (MSI). Help is now at hand, however, from a recent project which has come up with a range of new tools for efficiently processing MSI data.
