Short sleep linked to distracted secondary eating, drinking Posted: 11 Dec 2015 12:41 PM PST Research suggests a link between short sleep and obesity from secondary eating and drinking while engaged in another activity. Investigators assessed time spent on secondary eating and drinking as well as primary eating and drinking, with sleep duration as the principal independent variable.

Violence in Mexico affected children's mental health Posted: 11 Dec 2015 11:51 AM PST Children who lived in Juarez, Mexico -- once dubbed the murder capital of the world -- in 2010 have high levels of behavioral and emotional problems, according to new research.

Lava attraction: 74 new beetle species found hiding in plain sight on a Hawaiian volcano Posted: 11 Dec 2015 11:50 AM PST Within the limits of Haleakala volcano, Maui Island, Hawaii, the beetle fauna turns out to be not only extremely diverse, but quite abundant as well. When a professor looked thoroughly into the ground beetle populations in the area, he identified 116 species of round-waisted predatory beetles, including 74 new to science.

Potential of liquid biopsy for breast cancer patients Posted: 11 Dec 2015 11:50 AM PST Information gleaned from a liquid biopsy may help predict how individual women with advanced breast cancer will respond to certain therapies as well as reveal genetic mutations that can impact prognosis, according to two new studies.

Match-heads boost photovoltaic efficiency Posted: 11 Dec 2015 10:25 AM PST Crystal growth on a nano/microscale level produces "match-head"-like, three-dimensional structures that enhance light absorption and photovoltaic efficiency. This is the first large structure grown on a nanowire tip and it creates a completely new architecture for harnessing energy.

Spontaneous pressure regulation within artificial cells Posted: 11 Dec 2015 10:25 AM PST Living cells respond to threats in their environment. What if materials could do the same? Using a similar pressure-regulating mechanism to that found in cells, scientists created an artificial cell that responds to a sudden and possibly catastrophic change in its surroundings.

You can have your conductor and insulator, too Posted: 11 Dec 2015 10:25 AM PST By carefully tuning the chemical composition of a particular compound, researchers have created a topological crystalline insulator, whose bulk acts as an insulator but whose surface conducts electrical currents.

Small variations mean big changes in oxide’s transformation from insulator to conductor Posted: 11 Dec 2015 10:25 AM PST More efficient computers and other devices often begin with new materials. One promising option is vanadium dioxide, which rapidly transforms from an insulator to a conductor in femtoseconds. Scientists found that the dioxide responds non-uniformly on the nanoscale, contrary to prior assumptions.

Build a network, cellular style Posted: 11 Dec 2015 10:23 AM PST For the first time, biomolecular machines have been exploited to perform mechanical work to deform and dynamically assemble complex, far-from-equilibrium polymer networks. This development could lead to new pathways to make complex, robust polymer structures using biological molecules.

Intensive training affects the sleep, performance and mood of athletes, but more carbs may help Posted: 11 Dec 2015 10:17 AM PST Getting enough sleep is an essential part of any athlete's training program, but a new study reveals intensive bouts of exercise can make it hard to get 40 winks. Suspecting that intense exercise can lead to sleep disturbance, scientists studied the effects of two nine day periods of heavy training on 13 highly trained cyclists. The researchers monitored the athletes' moods, sleep patterns and performance before, during and after exercise.

Red deer make more out of less food during winter Posted: 11 Dec 2015 10:16 AM PST During the winter season, northern-latitude herbivores must cope with a food supply that is both restricted and of poorer quality. The ability of red deer to handle these extreme situations was the focus of a recent study. The study revealed that, even when good food is readily available, the animals eat only half as much in the winter as in the summer. They reduce the size of their gastrointestinal tract and extract nutrients more efficiently.

Health labels influence flavor perception Posted: 11 Dec 2015 10:15 AM PST Researchers found that food labels influence the perception of flavor. Light products are considered less tasty. Researchers at a flavor lab organized a flavor experiment with young Gouda cheese for a test audience of 129 people. Without knowing it, the participants tasted the same cheese several times, but each time with a different label, such as 'light' or 'reduced salt'.

Possibility to Completely Restore Human Bones Posted: 11 Dec 2015 10:15 AM PST Biomedical startup company Biom? is offering a synthetic bone equivalent used for bone restoration operations in odontology. The bone equivalent Cell'in is made from cellulose/hydroxyapatite composite. The analogical products in global market are usually created on the basis of synthetic polymers.

Neural stimulation offers treatment for 'dry eye' Posted: 11 Dec 2015 10:06 AM PST Scientists have developed a device that electronically stimulates tear production, which will offer hope to sufferers of dry eye syndrome, one of the most common eye diseases in the world.

A fishy tale of a sheep in wolf's clothing Posted: 11 Dec 2015 10:06 AM PST Scientists have developed a technique to perform dietary analysis of fish by analyzing microscopic tooth wear.

Using cycling to explain why physics isn't a drag Posted: 11 Dec 2015 10:06 AM PST Scientists and teachers have combined to develop a simple spreadsheet-based method of teaching aerodynamic drag to 14 and 15 year olds. By measuring the speed of one of their classmates riding a bike and taking a photo in order to measure the frontal area of the cyclist, the students were able to calculate the drag co-efficient.

Mapping downgoing plate topography: The 2005 Sumatra earthquake Posted: 11 Dec 2015 10:01 AM PST New geophysical data show that fault slip during the March 2005 magnitude 8.7 (Mw) earthquake off the west coast of northern Sumatra, Indonesia (also referred to as the Simeulue-Nias earthquake), was stopped by the topography on the downgoing plate.

Swiss students are not fond of brain-doping Posted: 11 Dec 2015 10:00 AM PST Switzerland has honest students: The vast majority of the students that were questioned were against pharmacological cognitive enhancement. Yet the topic should be addressed more actively by the universities, according to new research.

Volcanic event caused ice age during Jurassic Period Posted: 11 Dec 2015 09:44 AM PST Pioneering new research has shed new light on the causes behind an 'ice-age' that took place on Earth around 170 million years ago.

Review explores cancer screening, prevention, and treatment in people with mental illness Posted: 11 Dec 2015 09:44 AM PST A new report suggests that healthcare system and societal factors are just as critical as individual lifestyle factors in creating health disparities among people with metal illness.

Aural feedback for oral hygiene Posted: 11 Dec 2015 09:44 AM PST Researchers in Japan have discovered that how effectively we clean our teeth and how satisfied we are with the brushing job we do depends a lot on the sound of the bristles scrubbing against the enamel. They have described details of a futuristic toothbrush that might help with oral hygiene.

T-DM1 improved overall survival for heavily pretreated patients with HER2-pos breast cancer Posted: 11 Dec 2015 09:43 AM PST Among patients with HER2-positive, metastatic breast cancer that had progressed despite treatment with two or more forms of HER2-targeted therapy (trastuzumab [Herceptin] and lapatinib [Tykerb]), median overall survival was increased for those treated with trastuzumab emtansine (T-DM1 [Kadcyla]) compared with those who received treatment of physician's choice, according to results from the phase III TH3RESA clinical trial.

Earlier intervention leads to better weight recovery in children with multiple risk factors for weight faltering Posted: 11 Dec 2015 09:43 AM PST Young children who are underweight experienced greater weight recovery the earlier an intervention was started, and the recovery was more significant in children with multiple household risk factors, according to a study.

Climate change losses for Southeast Asia well above previous estimate Posted: 10 Dec 2015 03:21 PM PST Economic losses from the impacts of climate change in Southeast Asia could be 60% higher than previously estimated, reducing the region's gross domestic product (GDP) by up to 11% by 2100.
