| Posted: 31 Jan 2014 08:08 PM PST Behind every "Top 100" list are a generous sprinkling of personal bias and subjective decisions. Lacking the tools to calculate how factors like median home prices and crime rates actually affect the "best places to live," the public must take experts' analysis at face value. |
| Not so 'evil': Finance study makes case for hedging Posted: 31 Jan 2014 10:08 AM PST Business researchers have come up with the first scientific evidence that hedging against risk can increase a firm's value. |
| One planet, two stars: New research shows how circumbinary planets form Posted: 31 Jan 2014 10:07 AM PST Luke Skywalker's home planet Tatooine would have formed far from its current location in the Star Wars universe, a new study into its real world counterparts, observed by the Kepler space telescope, suggests. |
| Smart Notices could take us beyond copyright Posted: 31 Jan 2014 10:07 AM PST Dynamic Smart Notices could replace standard licencing agreements for software, online services and digital goods, according to a researchers. |
| Making color: When two red photons make a blue photon Posted: 31 Jan 2014 10:05 AM PST Can scientists generate any color of light? The answer is not really, but the invention of the laser in 1960 opened new doors for this endeavor. Scientists have now demonstrated a new semiconductor microstructure that performs frequency conversion. This design is a factor of 1000 smaller than previous devices. |
| Forensic experts compile guide on how to ID child abuse, starvation Posted: 31 Jan 2014 07:12 AM PST Forensic science experts have just published a comprehensive overview of forensic research that can be used to identify child abuse and starvation. |
| How neurons control fine motor behavior of the arm Posted: 31 Jan 2014 07:12 AM PST Motor commands issued by the brain to activate arm muscles take two different routes. As a research group has now discovered, many neurons in the spinal cord send their instructions not only towards the musculature, but at the same time also back to the brain via an exquisitely organized network. |
| Impaired cell division leads to neuronal disorder Posted: 31 Jan 2014 07:11 AM PST Researchers have discovered an amino acid signal essential for error-free cell division. This signal regulates the number of centrosomes in the cell, and its absence results in the development of pathologically altered cells. Remarkably, such altered cells are found in people with a neurodevelopmental disorder, called autosomal recessive primary microcephaly. |
| Early studies show microspheres may prevent bone infections after joint replacement Posted: 31 Jan 2014 06:35 AM PST While total joint surgeries have a low risk of infection -- between 1 and 3 percent -- in those rare instances when bone infection sets in, it can be a devastating setback for patients. Researchers have evaluated an application that may prevent implant-associated bone infections all together. |
| Success in targeted therapy for common form of lung cancer, study shows Posted: 31 Jan 2014 06:35 AM PST Researchers have found that a combination of two already-in-use drugs may have an effect on stopping the growth of the most common genetic subtype of lung cancer setting the stage for clinical trials. |
| Nine steps to save waterways and fisheries identified by researchers Posted: 31 Jan 2014 06:35 AM PST The key to clean waterways and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists. |
| Posted: 31 Jan 2014 05:35 AM PST Mating pairs of lemurs mirror each other's scent-marking behavior and even start to smell alike after they have reproduced. Matched scents are possibly a way to combine territory defenses or to advertise their relationship status to the rest of their group, according to researchers. Couples who haven't had kids yet spend the most time scent-marking and investigating each other's odors. |
| Vibrations influence circadian clock of fruit fly Posted: 31 Jan 2014 05:35 AM PST The internal circadian clock of a Drosophila (fruit fly) can be synchronized using vibrations, according to new research. The results of the study suggest that an animal's own movements can influence its clock. |
| Gastric bypass improves insulin secretion in pigs Posted: 31 Jan 2014 05:34 AM PST The majority of gastric bypass patients mysteriously recover from their type 2 diabetes within days, before any weight loss has taken place. A study has now shown that the insulin-producing beta cells increase in number and performance after the surgery. |
| Teaching young wolves new tricks: Wolves are considerably better imitators than dogs Posted: 31 Jan 2014 05:34 AM PST Although wolves and dogs are closely related, they show some striking differences. Scientists have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans. |
| New catalyst to convert greenhouse gases into chemicals Posted: 31 Jan 2014 05:32 AM PST Researchers have developed a highly selective catalyst capable of electrochemically converting carbon dioxide -- a greenhouse gas -- to carbon monoxide with 92 percent efficiency. The carbon monoxide then can be used to develop useful chemicals. |
| Diagnosis just a breath away with new laser that advances breath analysis for disease diagnosis Posted: 31 Jan 2014 05:32 AM PST Physics researchers have developed a new type of laser that will enable exciting new advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical greenhouse gases. |
| When the job search becomes a blame game Posted: 30 Jan 2014 06:14 PM PST A new book explores how white-collar job hunters in the U.S. blame themselves unnecessarily -- and suffer as a result -- when they cannot find work. |
| NSA pursues quantum technology Posted: 30 Jan 2014 06:08 PM PST Researchers explain how the revelation that the US National Security Agency is developing quantum computers has renewed interest and sparked debate on just how far ahead they are of the world's major labs looking to develop the same technology. |
| Imaging technique shows brain anatomy change in women with MS, depression Posted: 30 Jan 2014 06:07 PM PST A multicenter research team used a new, automated technique to identify shrinkage of a mood-regulating brain structure in a large sample of women with MS who also have a certain type of depression. |
| Posted: 30 Jan 2014 04:04 PM PST Researchers reporting today are the first to have utilized high-resolution electron microscopy to look at HIV infection within the actual tissue of an infected organism, providing perhaps the most detailed characterization yet of HIV infection in the gut. |
| Childhood depression may increase risk of heart disease by teen years Posted: 30 Jan 2014 01:44 PM PST Children with depression are more likely to be obese, smoke and be inactive, and can show the effects of heart disease as early as their teen years, according to a newly published. |
| What companies can learn from NASA tragedies Posted: 30 Jan 2014 01:44 PM PST Scientists have been researching how NASA recognizes "near-miss" events ever since the Columbia shuttle was destroyed in flight 11 years ago Saturday. A new study finds recognition of near-misses goes up when leaders emphasize project significance and weigh safety over other goals. |
| Lab clocks 'hot' electrons: Plasmon-generated electrons timed moving from nanorods to graphene Posted: 30 Jan 2014 01:44 PM PST Scientists time "hot" electrons as they transfer from excited plasmons in gold nanorods to graphene. Plasmonic nanoparticles are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly as well understood. Scientists are working on that, too. They suggest that the extraction of electrons generated by surface plasmons in metal nanoparticles may be optimized. |
| Video game teaches kids about stroke symptoms, calling 9-1-1 Posted: 30 Jan 2014 01:44 PM PST Children improved their knowledge of stroke symptoms and how to respond after playing a stroke education video game. They retained that knowledge for several weeks. |
| Researcher turns sights on prostate cancer, tissue engineering, blood vessel repair Posted: 30 Jan 2014 01:43 PM PST When biology and materials science converge, the results can be new materials that can be used to deliver targeted drugs, repair damaged arteries or rebuild failing tissues, such as the anterior cruciate ligament, the ACL injury that can end sports careers. One bioengineer is developing polymers designed to target all three. |
| Enhancing mussel conservation, pearl production Posted: 30 Jan 2014 01:43 PM PST Mollusk researchers in the United States and China are collaborating to promote freshwater mussel conservation, develop more robust and productive pearl-producing Chinese mussels, and possibly introduce a U.S. mussel to China that has the potential to produce colored pearls. |
| Genetically diverse cancer cells key to brain tumor resistance Posted: 30 Jan 2014 12:58 PM PST For a cancer cell, it pays to have a group of eccentric friends. Like X-Men characters, a group of cancer cells with diverse physical traits is safer, because it takes different strategies to kill each member. The more diverse the group, the better the chances are for individual cells to survive and join forces as a cohesive tumor. |
| Study supports new safety rule for truck drivers Posted: 30 Jan 2014 12:29 PM PST The US Department of Transportation's Federal Motor Carrier Safety Administration today released the findings of a field study that provides evidence that a revised provision in new hours-of-service regulations for truck drivers is more effective at combating fatigue than the previous version. The new trucking regulations took effect last July. |
| Sex-specific patterns of recovery from newborn brain injury revealed by animal study Posted: 30 Jan 2014 12:28 PM PST Physicians have long known that oxygen deprivation to the brain around the time of birth causes worse damage in boys than girls. Now a study by researchers conducted in mice reveals one possible reason behind this gender disparity and points to gender-specific mechanisms of brain repair following such injury. |
| More than one-third of women have hot flashes 10 years after menopause Posted: 30 Jan 2014 12:28 PM PST A team of researchers has found that moderate to severe hot flashes continue, on average, for nearly five years after menopause, and more than a third of women experience moderate/severe hot flashes for 10 years or more after menopause. Current guidelines recommend that hormone therapy, the primary medical treatment for hot flashes, not continue for more than 5 years. |
| 'Refund to savings’ tax-time savings experiment has impact on household finances Posted: 30 Jan 2014 12:28 PM PST Last year, almost 900,000 low- and moderate-income tax filers participated in a unique tax preparation savings intervention program, depositing approximately $5.9 million more into savings accounts than they would have without the intervention. As the 2014 tax season opens, the Refund to Savings (R2S) initiative continues. |
| Don't believe everything you read on the net about vertebroplasty, study says Posted: 30 Jan 2014 11:13 AM PST Most websites with information on vertebroplasty do not paint the full picture about the pros, cons and alternatives of the treatment. Therefore patients should always sit down with their physicians to thoroughly discuss their options, rather than take everything they read on the Internet as the full gospel, according to a new study. |
| Does caregiving cause psychological stress? It depends, says study of female twins Posted: 30 Jan 2014 11:13 AM PST A newly published study shows that the associations between caregiving and different types of psychological distress (depression, anxiety, perceived stress and perceived mental health) depend largely on a person's genes and upbringing -- and less so on the difficulty of caregiving. |
| Worry on the brain: Researchers find new area linked to anxiety Posted: 30 Jan 2014 11:13 AM PST Previous studies of anxiety in the brain have focused on the amygdala, but a team of researchers had a hunch that understanding a different brain area, the lateral septum (LS), could provide more clues into how the brain processes anxiety. Their instincts paid off -- the team has found a neural circuit that connects the LS with other brain structures in a manner that directly influences anxiety. |
| Complaints: Flying the not-so-friendly skies Posted: 30 Jan 2014 11:13 AM PST A new study shows that network carriers receive more complaints than cheaper airlines, regardless of actual service quality. |
| New computer, Edison, electrifies scientific computing Posted: 30 Jan 2014 11:13 AM PST A new supercomputer, named Edison, electrifies scientific computing. Edison can execute nearly 2.4 quadrillion floating-point operations per second (petaflop/s) at peak theoretical speeds. |
