RIVERSIDE, Calif. (http://www.ucr.edu) -- Most Americans go online for information and support about health-related issues. But what exactly are they looking for? Researchers at the University of California, Riverside shed light on this in a new study that examines how different people in different places use the internet to discuss their health. Titled "Demographic-Based Content Analysis of Online Health-Related Social media," the study was published today (June 13) in the Journal of Medical Internet Research.

ROCHESTER, Minn. -- Researchers at Mayo Clinic have identified the enzyme, called CD38, that is responsible for the decrease in nicotinamide adenine dinucleotide (NAD) during aging, a process that is associated with age-related metabolic decline. Results demonstrated an increase in the presence of CD38 with aging in both mice and humans. The results appear today in Cell Metabolism.

Washington, DC - June 9, 2016 -The microbial mix found in grape juice during the winemaking process may help shape the terroir of a finished wine, report food scientists at the University of California, Davis. In a study published in the May/June issue of mBio, an online open-access journal from the American Society of Microbiology, the researchers found that the microorganisms found in must - freshly-pressed grape juice, before fermentation - can be used as biomarkers to predict which metabolites will be found in the finished wine.

In the lead up to the World Barista Championships, University of Bath scientists say brewing more flavoursome coffee could be as simple as chilling the beans before grinding.

A team from the University working with renowned Bath coffee shop Colonna & Smalls found that chilling roasted beans before grinding resulted in narrower distribution of small particles, which during the brewing process allows access to more flavour from the same amount of coffee.

Modern intensive agriculture has generally led to the decline in farmland biodiversity, such as plants and animals. However, information on the impacts of human activities on soil microbial diversity is scarce, and often inconclusive. Such paucity is in part due to the difficulties in obtaining appropriate contrast samples for comparison.

DENVER, COLO. (JUNE 14, 2016) - New research shows that an over-the-counter sleep aid helps people suffering from occasional sleep difficulties fall asleep in less than 20 minutes, on average, and improves their reported quality of sleep. The study is the first-of-its-kind to characterize the sleep benefits of diphenhydramine HCI (DPH), marketed for decades as a sleep-aid.

Residents of Wink and neighboring Kermit have grown accustomed to the two giant sinkholes that sit between their small West Texas towns.

But now radar images taken of the sinkholes by an orbiting space satellite reveal big changes may be on the horizon.

A new study by geophysicists at Southern Methodist University, Dallas, finds the massive sinkholes are unstable, with the ground around them subsiding, suggesting the holes could pose a bigger hazard sometime in the future.

National surveys suggest ecstasy (the street name for the drug MDMA) use has decreased substantially among adolescents and young adults in the US since 2001; however, the recent phenomenon of "Molly" (ecstasy marketed as "pure MDMA") may be leading to underreporting of use as not all users are aware that "Molly" is a form of ecstasy.

OAK RIDGE, Tenn., June 13, 2016--A new study published in Nature Climate Change indicates soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands.

In addition to looking nice, covering soil with wood mulch can actually help reduce greenhouse gas emissions, UBC research shows.

In a recent study undertaken in Kelowna-area apple orchards and vineyards, UBC researchers discovered that using mulch in agriculture can cut nitrous oxide emissions up to 28 per cent.

BINGHAMTON, NY - Industrial manufacturing businesses can save over 30 percent on electrical bills, and cut greenhouse gas emissions by over 5 percent, by adjusting production schedules, according to new research from Binghamton University, State University of New York.

Up until recently, researchers thought they had the behaviors of ferroelectric materials mostly figured out.

"The conventional wisdom is that you can put almost any material under mechanical stress, and provided the stress is coherently maintained, the material will become ferroelectric or exhibit an electrical polarization," said James Rondinelli, assistant professor of materials science and engineering at Northwestern University's McCormick School of Engineering. "If you apply similar stresses to a compound that's already ferroelectric, then its polarization increases."

A paper by Brazilian researchers published in the journal Scientific Reports describes a study showing that a subgroup of olfactory neurons in the nasal cavity express a cellular receptor specializing in the transport of lipid molecules.

Terahertz radiation -- the band of electromagnetic radiation between microwaves and visible light -- has promising applications in security and medical diagnostics, but such devices will require the development of compact, low-power, high-quality terahertz lasers.

In this week's issue of Nature Photonics, researchers at MIT and Sandia National Laboratories describe a new way to build terahertz lasers that could significantly reduce their power consumption and size, while also enabling them to emit tighter beams, a crucial requirement for most practical applications.

New Haven, Conn. - Yale scientists have found a way to greatly boost the intensity of light waves on a silicon microchip using the power of sound.

Writing in the journal Nature Photonics, a team led by Peter Rakich describes a new waveguide system that harnesses the ability to precisely control the interaction of light and sound waves. This work solves a long-standing problem of how to utilize this interaction in a robust manner on a silicon chip as the basis for powerful new signal-processing technologies.
