Rapid response to kids' stroke symptoms may speed diagnosis Posted: 02 Jul 2015 03:38 PM PDT A rapid response plan for children at a hospital quickly identified stroke and other neurological problems. One in four children with stroke-like symptoms were diagnosed with stroke and 14 percent were diagnosed with other neurological emergency conditions, the study states.

'Map Of Life' predicts ET. (So where is he?) Posted: 02 Jul 2015 01:39 PM PDT The author of a new study of evolutionary convergence argues that the development of life on Earth is predictable, meaning that similar organisms should therefore have appeared on other, Earth-like planets by now. So why do we appear to be all alone in the universe?

Rumors of southern pine deaths have been exaggerated, researchers say Posted: 02 Jul 2015 01:11 PM PDT Researchers have a message for Southern tree farmers worried about unexplainable pine tree deaths: don't panic. A new study has analyzed growth in thousands of pine tree plots across the Southeast and indicates that 'southern pine decline' isn't happening on a large scale.

Astronomers predict fireworks from rare stellar encounter in 2018 Posted: 02 Jul 2015 01:11 PM PDT Astronomers are gearing up for high-energy fireworks coming in early 2018, when a stellar remnant the size of a city meets one of the brightest stars in our galaxy.

Infection with Wolbachia bacteria curbs fighting among fruit flies Posted: 02 Jul 2015 01:11 PM PDT Male fruit flies infected with the bacterium, Wolbachia, are less aggressive than those not infected, according to research. This is the first time bacteria have been shown to influence aggression.

Unexpected enzyme may resurrect roses' fading scents Posted: 02 Jul 2015 12:25 PM PDT Researchers working with roses have identified an enzyme which plays a key role in producing the flowers' sweet fragrances.

Déjà vu all over again:' Research shows 'mulch fungus' causes turfgrass disease Posted: 02 Jul 2015 12:15 PM PDT Inadvertently continuing a line of study they conducted about 15 years ago, a team of researchers recently discovered the causal agent for an emerging turfgrass disease affecting golf courses around the world.

Soundproofing with quantum physics Posted: 02 Jul 2015 12:15 PM PDT Scientists have shown that the road from abstract theory to practical applications needn't always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes.

Why the seahorse's tail is square Posted: 02 Jul 2015 12:13 PM PDT Why is the seahorse's tail square? An international team of researchers has found the answer and it could lead to building better robots and medical devices. In a nutshell, a tail made of square, overlapping segments makes for better armor than a cylindrical tail. It's also better at gripping and grasping.

The sting in dengue's tail Posted: 02 Jul 2015 12:13 PM PDT Scientists have identified how small changes in dengue's viral genome can affect the virus' ability to manipulate human immune defenses and spread more efficiently.

Ridges and valleys: Experiments open window on landscape formation Posted: 02 Jul 2015 12:13 PM PDT Geologists have seen ridges and valleys form in real time and -- even though the work was a fast-forwarded operation done in a laboratory setting -- they now have an idea of how climate change may impact landscapes.

Novel HIV vaccine regimen provides robust protection in non-human primates Posted: 02 Jul 2015 12:12 PM PDT A new study shows than an HIV-1 vaccine regimen, involving a viral vector boosted with a purified envelope protein, provided complete protection in half of the vaccinated non-human primates (NHPs) against a series of six repeated challenges with simian immunodeficiency virus (SIV), a virus similar to HIV that infects NHPs.

Vaccines and treatment for dengue virus possible Posted: 02 Jul 2015 11:23 AM PDT Researchers have determined the structure of a human monoclonal antibody which, in an animal model, strongly neutralizes a type of the potentially lethal dengue virus.

To conduct, or to insulate? That is the question Posted: 02 Jul 2015 11:22 AM PDT Researchers have identified a material that behaves as a conductor and an insulator at the same time, challenging current understanding of how materials behave, and pointing to a new type of insulating state.

Do you really think you're a foodie? Posted: 02 Jul 2015 11:22 AM PDT Think you're a foodie? Adventurous eaters, known as 'foodies,' are often associated with indulgence and excess. However, a new study shows just the opposite -- adventurous eaters weigh less and may be healthier than their less-adventurous counterparts.

Long-term memories are maintained by prion-like proteins Posted: 02 Jul 2015 10:28 AM PDT Researchers have uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time.

Viral protein in their sights Posted: 02 Jul 2015 10:27 AM PDT A team using electron cryomicroscopy has for the first time revealed at the atomic level the structure of a protein required for viral replication in vesicular stomatitis virus, a virus that is a model for a group of RNA viruses that includes Ebola and other threats to human health.

Telomeres linked to origins of idiopathic pulmonary fibrosis Posted: 02 Jul 2015 10:23 AM PDT Researchers have now discovered that telomeres, the structures that protect the chromosomes, are at the origin of pulmonary fibrosis. This is the first time that telomere damage has been identified as a cause of the disease. This finding opens up new avenues for the development of therapies to treat a disease for which there is currently no treatment.

Commonly prescribed drugs affect decisions to harm oneself and others Posted: 02 Jul 2015 10:23 AM PDT Healthy people given the serotonin-enhancing antidepressant citalopram were willing to pay almost twice as much to prevent harm to themselves or others than those given placebo drugs in a moral decision-making experiment. In contrast, the dopamine-boosting Parkinson's drug levodopa made healthy people more selfish, eliminating an altruistic tendency to prefer harming themselves over others.

What bee-killing mites can teach us about parasite evolution Posted: 02 Jul 2015 10:22 AM PDT An infestation of speck-sized Varroa destructor mites can wipe out an entire colony of honey bees in two to three years if left untreated. Pesticides help beekeepers rid their hives of these parasitic arthropods, which feed on the blood-like liquid inside of their hosts and lay their eggs on larvae, but mite populations become resistant to the chemicals over time.

Can autism be measured in a sniff? Posted: 02 Jul 2015 10:22 AM PDT Imagine the way you might smell a rose. You'd take a nice big sniff to breathe in the sweet but subtle floral scent. Upon walking into a public restroom, you'd likely do just the opposite -- abruptly limiting the flow of air through your nose. Now, researchers have found that people with autism spectrum disorder don't make this natural adjustment like other people do.

Encryption made easier: Just talk like a parent Posted: 02 Jul 2015 10:18 AM PDT A researcher has created an easier email encryption method – one that sounds familiar to parents who try to outsmart their 8-year-old child. The new technique gets rid of the complicated, mathematically generated messages that are typical of encryption software. Instead, the method transforms specific emails into ones that are vague by leaving out key words.

Water to understand the brain Posted: 02 Jul 2015 10:17 AM PDT To observe the brain in action, scientists and physicians use imaging techniques, among which functional magnetic resonance imaging (fMRI) is the best known. These techniques are not based on direct observations of electric impulses from activated neurons, but on one of their consequences. Indeed, this stimulation triggers physiological modifications in the activated cerebral region, changes that become visible by imaging. Until now, it was believed that these differences were only due to modifications of the blood influx towards the cells. By using intrinsic optical signals (IOS) imaging, researchers have now demonstrated that, contrary to what was thought, another physiological variation is involved: the activated neurons swell due to the massive entry of water.

First comprehensive analysis of the woolly mammoth genome completed Posted: 02 Jul 2015 10:17 AM PDT The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt Arctic life, including skin and hair development, insulin signaling, fat biology, and even traits such as small ears and short tails. A mammoth gene for temperature sensation was resurrected in the lab as a functional test.

Freezing single atoms to absolute zero with microwaves brings quantum technology closer Posted: 02 Jul 2015 10:15 AM PDT Physicists have found a way of using everyday technology found in kitchen microwaves and mobile telephones to bring quantum technology closer.

Working out in artificial gravity Posted: 02 Jul 2015 10:15 AM PDT Engineers have built a compact human centrifuge with an exercise component: a cycle ergometer that a person can pedal as the centrifuge spins. The centrifuge was sized to just fit inside a module of the ISS. After testing the setup on healthy participants, the team found the combination of exercise and artificial gravity could significantly lessen the effects of extended weightlessness in space -- more so than exercise alone.

How our sense of smell evolved, including in early humans Posted: 02 Jul 2015 08:21 AM PDT A group of scientists has studied how our sense of smell has evolved, and has even reconstructed how a long-extinct human relative would have been able to smell.

Dark matter map begins to reveal the Universe's early history Posted: 02 Jul 2015 08:20 AM PDT Researchers have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in Hawai'i.

Scientists warn of species loss due to human-made landscapes Posted: 02 Jul 2015 08:20 AM PDT Researchers say farmland is a poor substitute for natural areas but simple improvements could make a difference to biodiversity conservation.

Review indicates where cardio benefits of exercise may lie Posted: 02 Jul 2015 08:20 AM PDT A systematic review of 160 clinical trials of the cardiometabolic benefits of exercise shows which health indicators improve most with physical activity and for whom. For example, some of the benefits are greater for men, people under 50 and among those battling type 2 diabetes or other cardiovascular conditions.

Digesting bread and pasta can release biologically active molecules Posted: 02 Jul 2015 07:42 AM PDT Biologically active molecules released by digesting bread and pasta can survive digestion and potentially pass through the gut lining, suggests new research. The study reveals the molecules released when real samples of bread and pasta are digested, providing new information for research into gluten sensitivity.

Bad sleep habits linked to higher self-control risks Posted: 02 Jul 2015 07:41 AM PDT Poor sleep habits can have a negative effect on self-control, which presents risks to individuals' personal and professional lives, according to researchers. Psychologists concluded a sleep-deprived individual is at increased risk for succumbing to impulsive desires, inattentiveness and questionable decision-making.

Cause of acute liver failure in young children discovered Posted: 02 Jul 2015 07:41 AM PDT Acute liver failure is a rare yet life-threatening disease for young children. It often occurs extremely rapidly, for example, when a child has a fever. Yet in around 50 percent of cases it is unclear as to why this happens. Now, researchers working on an international research project have discovered a link between the disease and mutations in a specific gene.

Multiplying emerald ash borer decoys made easier Posted: 02 Jul 2015 07:41 AM PDT Emerald ash borers have no trouble reproducing themselves, as they have now spread through half the United States, but duplicating effective emerald ash borer decoys is not quite as easy. Now, engineers have devised an inexpensive method to produce hundreds of these fake bugs to aid in monitoring and controlling this pest.

Intrusiveness of old emotional memories can be reduced by computer game play procedure Posted: 02 Jul 2015 06:49 AM PDT Unwanted, intrusive visual memories are a core feature of stress- and trauma-related clinical disorders such as posttraumatic stress disorder (PTSD), but they can also crop up in everyday life. New research shows that even once intrusive memories have been laid down, playing a visually-demanding computer game after reactivating the memories may reduce their occurrence over time.

Traders' hormones' may destabilize financial markets Posted: 02 Jul 2015 06:49 AM PDT The hormones testosterone and cortisol may destabilize financial markets by making traders take more risks, according to a study.

Quantum computer storage may require the help of an intermediary to transmit information Posted: 02 Jul 2015 04:39 AM PDT Researchers have identified a system that could store quantum information for longer times, which is critical for the future of quantum computing.

Cooperative driving will become common: Data exchange between vehicles and road network Posted: 02 Jul 2015 04:37 AM PDT The just-completed international Celtic Plus CoMoSeF project involved the development of data exchange between vehicles and infrastructure. The resulting communication system provides drivers with real time information on road weather, road conditions and incidents.

Nanospiked bacteria are the brightest hard X-ray emitters Posted: 02 Jul 2015 04:36 AM PDT In a scientific breakthrough, researchers have fashioned bacteria to emit intense, hard X-ray radiation. They show that irradiating a glass slide coated with nanoparticle doped bacteria, turns the cellular material into hot, dense plasma, making this a useful table top X-ray source with several potential applications.

Authors raise concerns about industry dominance in diabetes research Posted: 01 Jul 2015 06:45 PM PDT Diabetes research is dominated by a small group of prolific authors, raising questions about the imbalance of power and conflict of interests in this field, argue experts in a new article.

End pharmacists' monopoly on selling certain drugs, argues British expert Posted: 01 Jul 2015 06:45 PM PDT Evidence is lacking that having a category of drugs that can be sold only by pharmacists or under their supervision ('pharmacy medicines') has benefits, writes a pharmacy professor in a new article.

A tale of two (soil) cities Posted: 01 Jul 2015 02:16 PM PDT Long-term differences in soil use and management influence not only the sizes and numbers of soil aggregates, but also what the pores inside them will look like, new research shows.

Make no bones about it: Female athlete triad can lead to problems with bone health Posted: 01 Jul 2015 12:23 PM PDT Participation in sports by women and girls has increased from 310,000 individuals in 1971 to 3.37 million in 2010. At the same time, sports-related injuries among female athletes have skyrocketed. According to a new study, women with symptoms known as the 'female athlete triad' are at greater risk of bone stress injuries and fractures.
