Broad receptive field responsible for differentiated neuronal activity

Tue, 16/12/2014 - 3:05pm
Some neurons are more active than others, even when they are positioned right next to each other and are one and the same neuron type. Researchers now have discovered the cause for this phenomenon.

A beetle named Marco Polo

Tue, 16/12/2014 - 3:05pm
A team of Chinese and Italian scientists has joined efforts to provide a key to the understudied phaleratus group of blister beetles. During their research the scientists have also discovered a new species from the genus Hycleus, which they named after Marco Polo.

How brain can distinguish good from bad smells

Tue, 16/12/2014 - 3:05pm
In fruit flies, the quality and intensity of odors can be mapped in the so-called lateral horn, scientists have found. They have created a spatial map of this part of the olfactory processing system in the fly brain and showed that the lateral horn can be segregated into three activity domains, each of which represents an odor category.

Composite plane life cycle assessment shows lighter planes are the future

Tue, 16/12/2014 - 3:05pm
A global fleet of composite planes could reduce carbon emissions by up to 15 percent, but the lighter planes alone will not enable the aviation industry to meet its emissions targets, according to new research.

Social connections keep workers on board

Tue, 16/12/2014 - 3:05pm
Contrary to popular belief, new research suggests that some employees adapt well to pressures caused by changes in the workplace. Pay cuts, reduced working hours, fewer training and promotion opportunities are just a few of the measures organizations employ to combat economic downturn and industry competition. Where previous research has suggested cut backs result in a demotivated and unhappy workforce, experts now say this might not necessarily be the case.

Hurricane-forecast satellites will keep close eyes on the tropics

Tue, 16/12/2014 - 3:05pm
A set of eight hurricane-forecast satellites is expected to give deep insights into how and where storms suddenly intensify -- a little-understood process that's becoming more crucial to figure out as the climate changes.

Scientist finds genetic wrinkle to block sun-induced skin aging

Tue, 16/12/2014 - 3:05pm
Scientists have shown that an enzyme is key in the aging of skin, which is caused mostly by sun exposure; mice lacking that enzyme developed fewer wrinkles, they report. The discovery points toward potential therapies that would preserve the strength of various tissues -- not just skin, but blood vessels and lung passages.

Is the Higgs Boson a piece of the matter-antimatter puzzle?

Tue, 16/12/2014 - 3:04pm
Several experiments, including the BaBar experiment have helped explain some – but not all – of the imbalance between matter and antimatter in the universe. Now theorists have laid out a possible method for determining if the Higgs Boson is involved. Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence.

Promising drug doubled positive effect in hormone-receptor positive breast cancer, study finds

Tue, 16/12/2014 - 3:04pm
In a groundbreaking study that offers new hope for women with advanced breast cancer, researchers have published final clinical trial results that showed the amount of time patients were on treatment without their cancer worsening (called progression-free survival) was effectively doubled in women with advanced breast cancer who took the experimental drug palbociclib.

Discovery of official clay seals support existence of biblical kings David and Solomon, archaeologists say

Tue, 16/12/2014 - 3:04pm
Six official clay seals found by an archaeological team at a small site in Israel offer evidence that supports the existence of biblical kings David and Solomon. Many modern scholars dismiss David and Solomon as mythological figures and believe no kingdom could have existed in the region at the time the Bible recounted their activities. The new finds provide evidence that some type of government activity was conducted there in that period.

Breast density helps better predict breast cancer risk

Tue, 16/12/2014 - 3:04pm
Adding a measurement of breast density better predicts women's risk for breast cancer, a study has found. The study evaluated the association between risk factors and breast cancer diagnosis based on more than 3,400 women who received digital mammograms, including women diagnosed with breast cancer and women not diagnosed with breast cancer between 2003 and 2013.

Extra vitamin E protected older mice from getting common type of pneumonia

Tue, 16/12/2014 - 3:04pm
Extra vitamin E protected older mice from a bacterial infection that commonly causes pneumonia. The study found that extra vitamin E helped regulate the mice’s immune system. The older mice were fed a diet containing extra amounts of vitamin E, the equivalent to about 200 IU/day consumed by humans -- about 10 times the Recommended Daily Allowance but well below the upper limit -- were far more resistant to the bacteria than the older mice that had a normal amount of vitamin E in their diet.

Men in recovery from Ebola should wear condoms for at least three months

Tue, 16/12/2014 - 1:26pm
A new article reports that despite a clear lack of research on male survivors of Ebola, the current recommended practice of waiting at least three months after recovery to have unprotected sex should be upheld.

Damming beavers are slowly changing the world: Growing beaver population affecting methane gas emissions

Tue, 16/12/2014 - 1:25pm
There are consequences of the successful efforts worldwide to save beavers from extinction. Along with the strong increase in their population over the past 100 years, these furry aquatic rodents have built many more ponds, establishing vital aquatic habitat. In doing so, however, they have created conditions for climate changing methane gas to be generated in this shallow standing water, and the gas is subsequently released into the atmosphere. In fact, 200 times more of this greenhouse gas is released from beaver ponds today than was the case around the year 1900, estimates an expert.

Worksite health promotion programs: Why don't people participate?

Tue, 16/12/2014 - 1:24pm
Worksite health promotion (WHP) programs are designed to help identify and address health and lifestyle issues, and are offered by 40–75% of employers in Europe and the US. But research suggests that a high proportion (50–75%) of workers do not participate. Why do so many employees choose not to take part? Researchers investigated the reasons for nonparticipation, and have identified a variety of barriers.

The bloody truth: How blood donations can save animals' lives

Tue, 16/12/2014 - 1:24pm
Blood transfusions are of importance not only in human medicine. Also animals do need blood donations. The University of Veterinary Medicine, Vienna operates a blood bank for dogs for more than a decade. But also cats can donate blood for acute emergencies. Horses need blood donations especially during operations that involve high blood loss. Sheep, goats and other ruminants require transfusions when plagued by serious infestations of parasites. Three vets from different areas of expertise explain how blood transfusions work with different animal species and how they can save lives.

Self-repairing subsea material

Tue, 16/12/2014 - 1:24pm
Embryonic faults in subsea high voltage installations are difficult to detect and very expensive to repair. Researchers believe that self-repairing materials could be the answer. The vital insulating material which encloses sensitive high voltage equipment may now be getting some 'first aid'.
