Students in right place, right time witness first-ever detected neutron star collision

Dom, 10/15/2017 - 22:00
New research published in Science details perhaps one of the biggest discoveries so far in the field of astrophysics: the merger of two neutron stars. Two graduate students and two professors at the University of Notre Dame contributed to studies published on the collision.

Most medical students overconfident, underprepared on nutrition guidelines

Dom, 10/15/2017 - 22:00
Researchers surveyed 257 medical students and found more than 55 percent were confident they could counsel patients on nutritional recommendations, but half did not achieve a passing score on a nutrition quiz. Of particular note, only 12 percent were aware of Dietary Reference Intakes (DRIs), a key guide to differentiated nutrition requirements, although more than 68 percent agreed that primary care physicians should counsel patients about nutrition.

NASA finds newly formed tropical storm lan over open waters

Dom, 10/15/2017 - 22:00
NASA-NOAA's Suomi NPP satellite provided a visible picture of newly formed Tropical Storm Lan in the Northwestern Pacific Ocean.

Some faiths more likely to turn to religion for answers to science

Dom, 10/15/2017 - 22:00
When it comes to seeking answers to questions about science, evangelical and black Protestants and Mormons are more likely than the general population to turn to religion, according to a new study.

Breaking: the first light from two neutron stars merging

Dom, 10/15/2017 - 22:00
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on Aug. 17, 2017.

Heads-up, CEOs -- corporate social responsibility may get you fired, study finds

Dom, 10/15/2017 - 22:00
Investing in product safety, employee diversity and carbon footprint reduction are all examples of corporate social responsibility (CSR) that can result in high praise for a chief executive -- or get them fired -- according to new research from the University of Notre Dame.

An epigenetic key to unlock behavior change

Dom, 10/15/2017 - 22:00
A new study reveals how epigenetics interact with genes to shape different feeding behaviors in fruit flies. This research unlocks the molecular mechanism that leads 'rover' flies to forage for food more than 'sitter'[ flies. It is the first study of its kind to show a causal link between epigenetics, genetics and behavior.

Risk of Caesarean section is heritable

Dom, 10/15/2017 - 22:00
Women born by Caesarean section are more than twice as likely to develop FDP when giving birth than women born naturally. This is the conclusion of a study by a team of evolutionary biologists at the University of Vienna headed by Philipp Mitteroecker. Using a mathematical model, the team was able to explain the paradoxical phenomenon that natural selection did not lead to the reduction in the rates of obstructed labor.

The importance of asymmetry in bacteria

Dom, 10/15/2017 - 22:00
Research reveals a protein that acts as a vacuum cleaner of the membrane and which could be a potential new target for antibiotics.

Doctors urged to make a public commitment to talk to their patients about guns

Dom, 10/15/2017 - 22:00
In the wake of the Las Vegas mass shooting, Garen Wintemute, MD, MPH, from the Violence Prevention Program at UC Davis, says that if Congress and the White House won't do anything to stop gun violence, then doctors must take action. In a pointed editorial published in Annals of Internal Medicine, Dr. Wintemute urges physicians to make a public commitment (go.annals.org/commit-now) to talk to their patients about firearms.

Mechanism explains how seizures may lead to memory loss

Dom, 10/15/2017 - 22:00
A team of researchers reveals a mechanism that can explain how even relatively infrequent seizures can lead to long-lasting cognitive deficits in animal models.

Stress might be just as unhealthy as junk food to digestive system

Dom, 10/15/2017 - 22:00
We all know that a poor diet is unhealthy, but a new study finds that stress may just as harmful to our bodies as a really bad diet.

Gravitational waves detected after collision of neutron stars 120 million light years away

Dom, 10/15/2017 - 22:00
Tel Aviv University researchers have confirmed that gravitational 'ripples in space' occur after the collision of neutron stars, very small (typically 18 miles across) and very dense bodies that are the remains of a massive star after a supernova explosion.

Novel reagent detects memory immune response in vaccinated animals

Dom, 10/15/2017 - 22:00
Researchers have developed a novel reagent capable of detecting rare, antigen-specific B cells that indicate successful vaccination in veterinary animals.

NASA sees Tropical Depression Khanun sissipating in Gulf of Tonkin

Dom, 10/15/2017 - 22:00
NASA's Terra satellite passed over Tropical Storm Khanun after it had passed over southern China and began dissipating in the Gulf of Tonkin.

Family members play important role in managing chronic illness

Dom, 10/15/2017 - 22:00
Family members often play an important role in managing chronic illnesses, and a family approach may produce more effective, long-term benefits for the patient, according to a Penn State researcher.

Chemical treatment improves quantum dot lasers

Dom, 10/15/2017 - 22:00
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research at Los Alamos National Laboratory's Nanotech Team, the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.

Neutron star merger directly observed for the first time

Dom, 10/15/2017 - 22:00
On August 17, 2017, scientists made the first direct observation of a merger between two neutron stars -- the dense, collapsed cores that remain after large stars die in a supernova explosion. The merger is the first cosmological event observed in both gravitational waves -- ripples in the fabric of spacetime -- and the entire spectrum of light, from gamma rays to radio waves. University of Maryland researchers played key roles in detecting signals of the historic event.

Study: Break the attachment before selling your stuff

Dom, 10/15/2017 - 22:00
Ever tried to sell something you've owned for a while on Craigslist and found that no one is willing to pony up what you're asking? It's because you're asking too much.

NASA sees Hurricane Ophelia lashing Ireland

Dom, 10/15/2017 - 22:00
NASA-NOAA's Suomi NPP satellite provided a thermal view of the clouds in hurricane Ophelia as it lashed Ireland. The Global Precipitation Measurement mission core satellite provided a look at the rainfall that was affecting the Emerald Isle.
