Ageing star blows off smoky bubble

In the faint southern constellation of Antlia the careful observer with binoculars will spot a very red star, which varies slightly in brightness from week to week. This very unusual star is called U Antliae and new observations with...Show More Summary

Fish may use different behaviors to protect against parasites

New research indicates that fish may adapt their behaviour to defend against parasite infection. The findings are published in the Journal of Zoology. When investigators studied Atlantic salmon, clear differences in parasite load existed between behaviourally-modified fish and those able to exhibit the normal repertoire of behaviours.

Obesity may adversely affect sperm quality

The journal Andologia has published the first report of abnormal sperm parameters in obese men based on computer aided sperm analysis. The findings suggest that clinicians may need to factor in paternal obesity prior to assisted reproduction. In...Show More Summary

Prime candidate to explain cosmic ray sea runs short of energy

Cassiopeia A is a famous supernova remnant, the product of a gigantic explosion of a massive star about 350 years ago. Although discovered in radio observations 50 years ago, now we know that its emitted radiation spans from radio through high-energy gamma rays. Show More Summary

Pulling, not pushing, silk could revolutionize how greener materials are manufactured

New insights into how animals spin silk could lead to new, greener ways of producing synthetic fibres, according to academics at the University of Sheffield. Researchers from the University of Sheffield's Department of Material Science and Engineering have shown that animals spin silk by pulling rather than pushing it out of their bodies.

BU: HPV vaccine associated with improved fertility in some women

More than 40 percent of American teens are now getting vaccinated against human papillomavirus (HPV). But, despite HPV infection being associated with reduced semen quality and lower pregnancy rates, there is still public concern about...Show More Summary

End-of-summer Arctic sea ice extent is eighth lowest on record

Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite data by NSIDC...Show More Summary

PET imaging tracks Zika virus infection, disease progression in mouse model

For the first time, scientists have used Positron Emission Tomography (PET) imaging to study brain inflammation following Zika virus infection in mice, according to a study recently published online in the journal Molecular Imaging and Biology. The technology has the added benefit of allowing investigators to study the progression of the disease over time.

Clear tactics, but few easy solutions, for hospitals combating ransomware

PROVIDENCE, R.I. [Brown University] -- Especially cruel hackers know that lives are on the line when they hold a hospital's computer systems hostage, as they did in the May 12 attack dubbed WannaCry, which locked down many overseas hospitals with the demand for a ransom. Show More Summary

Landmark study suggests risks vary widely in drone-human impacts

New Virginia Tech research suggests there's wide variation in the risk that unmanned aircraft pose to people on the ground. Many of the most promising applications for these aircraft -- including package delivery, public safety, and traffic management -- entail flights over people and raise the possibility, however unlikely, of an impact between the aircraft and a human.

Security cameras are vulnerable to attacks using infrared light -- Ben Gurion U. study

BEER-SHEVA, Israel...Sept. 19, 2017 - Ben-Gurion University of the Negev (BGU) researchers have demonstrated that security cameras infected with malware can receive covert signals and leak sensitive information from the very same surveillance...Show More Summary

Tiny lasers from a gallery of whispers

WASHINGTON, D.C., Sept. 19, 2017 -- Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a phenomenon similar to an effect observed in...Show More Summary

What web browsers and proteins have in common

COLUMBUS, Ohio -- Researchers in the United States and Germany have just discovered a previously overlooked part of protein molecules that could be key to how proteins interact with each other inside living cells to carry out specialized...Show More Summary

Groundbreaking investigative effort identifies gonorrhea vaccine candidates

CORVALLIS, Ore. - Researchers at Oregon State University have identified a pair of proteins that show promise as the basis for a gonorrhea vaccine. The findings are an important step toward a potential new weapon in the fight against...Show More Summary

NASA sees Tropical Depression Norma's small area of strength

Infrared imagery from NASA's Aqua satellite has revealed that the area of strongest storms within now Tropical Depression Norma has diminished. The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite analyzed Norma in infrared light. Show More Summary

What's the latest on gut microbiota?

How many undergraduate classes in microbiology -- or any scientific field, for that matter -- can say they're published in a peer-reviewed journal? "It's very rare, especially with such a large class size," says Chiara Gamberi, an affiliate...Show More Summary

Management studies: Dishonesty shift

Lying comes more easily to people in teams: Behavioral scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich have shown in an experimental study why groups are more likely to behave unethically than individuals. Honesty is a virtue and generally lauded as a vital moral value. Show More Summary

Cell-based therapy success could be boosted by new antioxidant

Cell therapies being developed to treat a range of conditions could be improved by a chemical compound that aids their survival, research suggests. Lab tests found that the man-made molecule - a type of antioxidant - helps to shieldShow More Summary

Community intervention among low-income patients results in improved blood pressure control

Low-income patients in Argentina with uncontrolled high blood pressure who participated in a community health worker-led multicomponent intervention experienced a greater decrease in systolic and diastolic blood pressure over 18 months than did patients who received usual care, according to a study published by JAMA.
