At-risk patients, such as those with HIV or transplant recipients, could benefit from potentially life-saving study carried out by a University of Surrey led group of international researchers.

Researchers produce detailed map of potential Mars rover landing site

Mié, 04/19/2017 - 22:00
Mineral deposits in a region on Mars called Northeast Syrtis Major suggest a plethora of once-habitable environments. By mapping those deposits in the region's larger geological context, the research could help set the stage for a possible rover mission.

Discrimination contributes to pediatric asthma rates in African American and Latino youth

Mié, 04/19/2017 - 22:00
In a new study published in CHEST, investigators found that African American children who reported experiencing discrimination had almost twice the probability of having asthma than their peers who did not experience/report discrimination. Among African American children with asthma, discrimination was also associated with a greater probability of having poorly controlled asthma. For Mexican American children, discrimination and socioeconomic status (SES) act together with discrimination having an effect on asthma only among low-SES children.

What else can fingers tell us?

Mié, 04/19/2017 - 22:00
According to HSE researchers, men with a high 2D:4D ratio (i.e. those whose index finger is longer than their ring finger) tend to be better educated. These findings are presented in the paper '2D: 4D and lifetime educational outcomes: Evidence from the Russian RLMS survey' in Personality and Individual Differences.

Can virtual reality help us prevent falls in the elderly and others?

Mié, 04/19/2017 - 22:00
Every year, falls lead to hospitalization or death for hundreds of thousands of elderly Americans. Standard clinical techniques generally cannot diagnose balance impairments before they lead to falls. But researchers from the University of North Carolina at Chapel Hill and North Carolina State University have found evidence that virtual reality (VR) could be a big help - not only for detecting balance impairments early, but perhaps also for reversing those impairments and preventing falls.

Supplement can lessen kidney damage linked to genetic mutations in transgenic fruit flies

Mié, 04/19/2017 - 22:00
An off-the-shelf dietary supplement available for pennies per dose demonstrated the ability to reverse cellular damage linked to specific genetic mutations in transgenic fruit flies, an experimental model of genetic mutation-induced renal cell injury that features striking similarities to humans, a Children's National Health System research team reports April 20 in Journal of the American Society of Nephrology.

New NSF special report released ahead of Earth Day

Mié, 04/19/2017 - 22:00
From flowers' microscopic cells to thunderstorms called supercells, researchers funded by the National Science Foundation (NSF) are studying the science of spring. Now, in time for Earth Day, a new NSF special report -- April Showers Bring...The Science of Spring -- looks at what makes spring such a vibrant, and sometimes dangerous, season.

Bergamotene -- alluring and lethal for Manduca sexta

Mié, 04/19/2017 - 22:00
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, describe a gene in Nicotiana attenuata which enables the plant to solve the dilemma that arises when a pollinator is also an herbivore. NaTPS38 regulates the production of (E)-alpha-bergamotene. At night, the tobacco flowers produce this volatile which is attractive to tobacco hawkmoths, during the day, the tobacco leaves emit the compound to lure predatory bugs to feed on the moths' larvae.

Hubble celebrates 27 years with two close friends

Mié, 04/19/2017 - 22:00
This stunning cosmic pairing of the two very different looking spiral galaxies NGC 4302 and NGC 4298 was imaged by the NASA/ESA Hubble Space Telescope. The image brilliantly captures their warm stellar glow and brown, mottled patterns of dust. As a perfect demonstration of Hubble's capabilities, this spectacular view has been released as part of the telescope's 27th anniversary celebrations.

Mindfulness class helped women, but not men, overcome 'negative affect'

Mié, 04/19/2017 - 22:00
Few studies have looked at whether mindfulness meditation is equally effective among men and women in addressing mood, but a new study in a college setting found a substantial difference.

Research underlines positive impact of press freedom on stock markets

Mié, 04/19/2017 - 22:00
In one of the first studies to assess the relationship between a country's Press Freedom Index and its stock market characteristics, researchers at the University of Luxembourg have highlighted how press freedom is linked to stock market volatility, and why this is beneficial for the overall economy.

The formation of gold deposits in South Africa

Mié, 04/19/2017 - 22:00
The Witwatersrand basin in South Africa hosts the largest known gold repository on Earth -- but how was it formed? Scientists of the GEOMAR Helmholtz Centre of Ocean Research Kiel and Canadian research institutes were able to figure out how parts of the Earth's largest gold deposits formed about three billion years ago. Crude oil and hot hydrothermal fluids played a major role.

Can we see a singularity, the most extreme object in the universe?

Mié, 04/19/2017 - 22:00
Scientists at the Tata Institute of Fundamental Research have found new ways to detect a bare or naked singularity, the most extreme object in the universe. This finding has possible astrophysical implications.

Immune discovery points to therapies to improve stroke recovery

Mié, 04/19/2017 - 22:00
Having a stroke damages immune cells as well as affecting the brain, research from the University of Edinburgh has found.

Ancient enzyme protects lungs from common irritant produced by bugs and mold

Mié, 04/19/2017 - 22:00
