A new light-trapping sensor, developed by a University at Buffalo-led team of engineers and described in an Advanced Optical Materials study, makes infrared absorption more sensitive, inexpensive and versatile. It may improve scientists’ ability use to sleuth out performance-enhancing drugs in blood samples, tiny particles of explosives in the air and more.
Some of the world’s tiniest crystals are known as “artificial atoms” because they can organize themselves into structures that look like molecules, including “superlattices” that are potential building blocks for novel materials. Now scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have made the first observation of these nanocrystals rapidly forming superlattices while they are themselves still growing.

Dosenbach, MD, PhD, an assistant professor of pediatric and developmental neurology at Washington University School of Medicine in St. Louis, and colleagues used imaging techniques to collect a massive amount of data on individual brains. Their work led to 10 individual-specific connectomes — detailed maps of neural brain connections that reveal spatial and organizational variability in brain networks.
An international team of researchers has shown in unprecedented detail that prehistoric farmers took their animals away from permanent settlements to graze in more fertile areas – probably because of high demand for land locally.
WASHINGTON -- Contrary to public perception and many media accounts, women and men report similar levels of work-family conflicts, both in the form of work interfering with family and family interfering with work, according to research published by the American Psychological Association.
In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, the researchers found an unexpected mode for how galaxies acquired matter: intergalactic transfer. Supernova explosions eject copious amounts of gas from galaxies, causing atoms to be transported from one galaxy to another via powerful galactic winds.
Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The paper was published online today in Nature.
Stem cell centers claim to offer effective treatment to patients with heart failure, despite the fact that the treatment is not approved for such use by the U.S. Food and Drug Administration (FDA), says the author of research letter in the current issue of JAMA Internal Medicine.
An ice cream cone on a hot July day can be a tasty way to beat the heat, but if you’re one of the millions of people who have sensitive teeth, then that cold treat can be a real pain. So, what causes your teeth to fear the sweet embrace of cold, delicious treats?

By analyzing the DNA of two prehistoric dogs from Germany, an international research team led by Krishna R. Veeramah, PhD, Assistant Professor of Ecology & Evolution in the College of Arts & Sciences at Stony Brook University, has determined that their genomes were the probable ancestors of modern European dogs. The finding, to be published in Nature Communications, suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.

The connection between slowed walking speed and declining mental acuity appears to arise in the right hippocampus, a finger-shaped region buried deep in the brain at ear-level, according to a 14-year study conducted by scientists at the University of Pittsburgh Graduate School of Public Health.
Climate change from rising levels of carbon dioxide (CO2) is having two major effects in our seas - global warming and ocean acidification - and the combination of these threats is affecting marine life from single organisms to species communities.
Tweets about political topics that include moral and emotional language are more likely to spread within the ideological networks of the sender, a team of researchers has found. Its study examined Twitter messages related to gun control, climate change, and same-sex marriage.
New research by Berkeley Lab scientists could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of “soft” semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.
This research found that light makes migraine headaches more painful and induces negative emotions and unpleasant physical sensations. Laboratory studies identify previously unknown connections between nerve cells in the eye and neurons in the brain that regulate physiological, autonomic, endocrine and emotional responses. These findings offer promising path forward for researchers in treatment of migraines.
If your attic is full of stuff you no longer use but can’t bear to give away, a new study may offer you a simple solution. Researchers found that people were more willing to give away unneeded goods that still had sentimental value if they were encouraged to take a photo of these items first.
Different types of memories stored in the same neuron of the marine snail Aplysia can be selectively erased, according to a new study by researchers at Columbia University Medical Center (CUMC) and McGill University and published today in Current Biology.

A new study by a UW-Madison undergraduate not only firms up the idea that we exist in one of the holes of the Swiss cheese structure of the cosmos, but helps ease the apparent disagreement between different measurements of the Hubble Constant, the unit cosmologists use to describe the rate at which the universe is expanding today.
A new study finds that exposure to a widespread outdoor fungus can increase cell damage (oxidative stress) in the airways. This spike weakens the airways’ barrier defense system that, when functioning normally, removes infection- and allergy-causing organisms (mucociliary clearance).
Northern Congo’s notorious elephant poacher and ivory trafficker Daring Dissaka, 39, has been convicted and sentenced to five years imprisonment.
Baby teeth from children with autism contain more toxic lead and less of the essential nutrients zinc and manganese, compared to teeth from children without autism, according to a study funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. The researchers studied twins to control genetic influences and focus on possible environmental contributors to the disease. The findings, published June 1 in the journal Nature Communications, suggest that differences in early-life exposure to metals, or more importantly how a child’s body processes them, may affect the risk of autism.
