Mental stress may cause reduced blood flow in hearts of young women with heart disease

Mental stress may cause reduced blood flow in the heart muscle of younger women with heart disease. Younger women with heart disease are more susceptible to reduced blood flow from mental stress compared to men and older patients, new research has found.

Biomarkers may help better predict who will have a stroke

People with high levels of four biomarkers in the blood may be more likely to develop a stroke than people with low levels of the biomarkers, according to a new study.

Can one cosmic enigma help solve another?

Astrophysicists have proposed a clever new way to shed light on the mystery of dark matter, believed to make up most of the universe. The irony is they want to try to pin down the nature of this unexplained phenomenon by using another, an obscure cosmic emanation known as 'fast radio bursts.'

Whiskers help animals sense the direction of the wind

Rats use information from their whiskers to localize an airflow source, new research has shown. This discovery could pave the way for the design of novel airflow measurement devices that imitate these biological sensors, say the researchers.

Global climate models do not easily downscale for regional predictions

One size does not always fit all, especially when it comes to global climate models, according to climate researchers who caution users of climate model projections to take into account the increased uncertainties in assessing local climate scenarios.

Feeling the force between sand grains

For the first time, researchers have measured how forces move through 3-D granular materials, determining how this important class of materials might pack and behave in processes throughout nature and industry.

Chew on this: How we believe our meat is raised can influence how it tastes

Our beliefs about how farm animals are raised -- whether on 'factory farms' or in more humane conditions -- can shape our meat-eating experience, from how we think it smells and tastes to how much we'd be willing to pay for it.

Asthma risk increases when child had bronchiolitis

Asthma risk increased 17 times when children who had bronchiolitis in the first two years of life also had a common variation of the Plasminogen activator inhibitor-1 gene, new research shows.

Mutually helpful species become competitors in benign environments

Nature abounds with examples of mutualistic relationships. Think of bees pollinating flowers whose nectar nourishes the bees. Each species benefits the other, and together their chances of survival are better than if they lived apart. Show More Summary

Tipped out: Gratuities present challenges for restaurant operations

Tipping in restaurants is a widespread practice in need of reform, according to a new study. Investigators found that tipping poses significant challenges for restaurants, with managers seeing difficulties in hiring chefs and maintaining a cordial workplace environment. Surprisingly, servers welcomed changes to how tips are divvied up, even at the risk of less income.

Smart helmet for football players may help detect concussions

A smart helmet that can help diagnose concussions in football players is being developed by medical students. Using the smart helmet, the team hopes players of all ages will be taken off the field immediately after a hit, instead of continuing to participate while injured.

Concussions and brain injury: Can omega-3 intake aid in brain health recovery?

The treatment of concussions and traumatic brain injury (TBI) is a clinical challenge. Clinical studies thus far have failed to identify an effective treatment strategy when a combination of targets controlling aspects of neuroprotection, neuroinflammation, and neuroregeneration is needed.

New research shows impact of Crohn's disease on brain function

Crohn's disease sufferers experience slower response times than matched individuals that do not have the disease, new research demonstrates.

Comparing coronary artery calcium scores in patients with psoriasis, diabetes

Assessing coronary artery calcium (CAC) is a measure of the severity of atherosclerosis (clogged arteries) and a cornerstone for screening for risk of future cardiac events. The inflammatory skin condition psoriasis has been associated with increased risk of cardiovascular disease. Type 2 diabetes is a high-risk disease associated with increased cardiovascular risk.

HIV-infected adults with depression have increased risk for heart attack

Among more than 26,000 human immunodeficiency virus (HIV)-infected adults, those with major depressive disorder (MDD) were more likely to experience a heart attack than those without MDD, according to a study.

Study shows diabetes treatment helps reduce weight in children with autism

A drug that's been used for decades in the treatment of type 2 diabetes is proving effective in helping to control weight gain in children who are treated for autism spectrum disorder, according to a new study.

Scientists identify spark plug that ignites nerve cell demise in ALS

Scientists have pinpointed an enzyme that triggers rapid demise of nerve cells in people with ALS. The research team describes a molecular chain of events that culminates in the stripping of the protective coating around axons, the slender projections that carry signals from one neuron to the next.

One of the most significant Etruscan discoveries in decades names female goddess Uni

Archaeologists translating a very rare inscription on an ancient Etruscan temple stone have discovered the name Uni -- an important female goddess. The discovery indicates that Uni -- a divinity of fertility and possibly a mother goddess...Show More Summary

Bio-inspired tire design: Where the rubber meets the road

Scientists have recently created new bio-inspired film-terminated structures with unique friction characteristics that could have positive industrial implications for, among other things, tires.

35 years on, Voyager's legacy continues at Saturn

Saturn, with its alluring rings and numerous moons, has long fascinated stargazers and scientists. After an initial flyby of Pioneer 11 in 1979, humanity got a second, much closer look at this complex planetary system in the early 1980s through the eyes of NASA's twin Voyager spacecraft.
