EurekAlert! - Jue, 06/22/2017 - 22:00
The immunotherapy nivolumab is kinder than chemotherapy for people with advanced head and neck cancer -- easing many of the negative effects of the disease on patients' quality of life.

Atomic imperfections move quantum communication network closer to reality

EurekAlert! - Jue, 06/22/2017 - 22:00
An international team led by the University of Chicago's Institute for Molecular Engineering has discovered how to manipulate a weird quantum interface between light and matter in silicon carbide along wavelengths used in telecommunications.

Research accelerates quest for quicker, longer-lasting electronics

EurekAlert! - Jue, 06/22/2017 - 22:00
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential.In a paper published today in 'Science Advances,' Jing Shi, a professor of physics and astronomy at UC Riverside and colleagues MIT and Arizona State University report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a 'heterostructure.'

NASA adds up Tropical Storm Cindy's rainfall

EurekAlert! - Jue, 06/22/2017 - 22:00
Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017 and bringing a lot of rain with it. That rainfall was measured by NASA using satellite data.

Genes, ozone, and autism

EurekAlert! - Jue, 06/22/2017 - 22:00
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism.

Making ferromagnets stronger by adding non-magnetic elements

EurekAlert! - Jue, 06/22/2017 - 22:00
Researchers at the US Department of Energy's Ames Laboratory discovered that they could functionalize magnetic materials through a thoroughly unlikely method, by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy.

Bird's eye perspective

EurekAlert! - Jue, 06/22/2017 - 22:00
Harvard Medical School researchers have now provided the first insight into the perplexing question of how humans developed their daytime vision.

Does the emperor have clothes?

EurekAlert! - Jue, 06/22/2017 - 22:00
Discovered more than two decades ago, the hormone leptin has been widely hailed as the key regulator of leanness. Yet, the pivotal experiments that probe the function of this protein and unravel the precise mechanism of its action as a guardian against obesity are largely missing.

Cut US commercial building energy use 29 percent with widespread controls

EurekAlert! - Jue, 06/22/2017 - 22:00
The US could slash its energy use by the equivalent of what is currently used by 12 to 15 million Americans if commercial buildings fully used energy-efficiency controls nationwide.

New 3-D model predicts best planting practices for farmers

EurekAlert! - Jue, 06/22/2017 - 22:00
The University of Illinois and the Partner Institute for Computational Biology in Shanghai developed a computer model to predict the yield of different crop cultivars in a multitude of planting conditions. Published in BioEnergy Research, the model depicts the growth of 3-D plants, incorporating models of the biochemical and biophysical processes that underlie productivity.

By far, men garner most coveted speaking slots at virology meetings

EurekAlert! - Jue, 06/22/2017 - 22:00
In their recent study, published in the Journal of Virology, the University of Wisconsin-Madison researchers examined 35 years worth of invited speaker rosters from four prominent virology meetings, including the American Society for Virology, which is hosting its annual meeting in Madison, Wisconsin starting June 24, 2017. They found that men were overwhelmingly represented. For example, between 1982 and 2017, 77 percent of the speakers at ASV's annual meetings were male.

Lights out: The neural relationship between light and sleep

EurekAlert! - Jue, 06/22/2017 - 22:00
While a great deal is known about how light affects circadian rhythms, little is known about the direct effects of light on sleep: Why do we tend to wake up if the lights are flipped on in the middle of the night? Why does darkness make us sleepy? Caltech researchers in the laboratory of Professor of Biology David Prober say they have discovered at least part of the answer: a specific protein in the brain that responds to light and darkness to set the correct balance between sleep and wakefulness.

Fungal toxins easily become airborne, creating potential indoor health risk

EurekAlert! - Jue, 06/22/2017 - 22:00
Toxins produced by three different species of fungus growing indoors on wallpaper may become aerosolized, and easily inhaled. The findings, which likely have implications for 'sick building syndrome,' were published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Experts uncover first molecular events of organ rejection

EurekAlert! - Jue, 06/22/2017 - 22:00
Researchers at the University of Pittsburgh and the University of Toronto have uncovered the first molecular steps that lead to immune system activation and eventual rejection of a transplanted organ.

Anti-epilepsy drug restores normal brain activity in mild Alzheimer's disease

EurekAlert! - Jue, 06/22/2017 - 22:00
In a recent feasibility study, BIDMC tested an anti-epileptic drug for its potential impact on the brain activity of patients with mild Alzheimer's disease. The team documented changes in patients' EEGs that suggest the drug could have a beneficial effect.

Patient race & gender are important in predicting heart attack in the emergency department

EurekAlert! - Jue, 06/22/2017 - 22:00
Researchers at the George Washington University published research finding that certain symptoms are more and less predictive of patients' risk for acute coronary syndrome, which includes heart attack, in patients of different gender and race.

Bioengineers create more durable, versatile wearable for diabetes monitoring

EurekAlert! - Jue, 06/22/2017 - 22:00
Researchers at The University of Texas at Dallas are getting more out of the sweat they've put into their work on a wearable diagnostic tool that measures three diabetes-related compounds in microscopic amounts of perspiration. In a study published recently in Nature Scientific Reports, the team describes their wearable diagnostic biosensor that can detect three interconnected compounds - cortisol, glucose and interleukin-6 - in perspired sweat for up to a week without loss of signal integrity.
