NIST expands database that helps identify unknown compounds in milk

Got milk? Most people have seen the famous ads featuring celebrities that highlight the importance of drinking milk for building strong bones. Research shows that milk has other benefits, especially for babies, such as helping them grow and strengthening their immune systems. But scientists still don't understand exactly how milk does these things.

NASA tracks Hanna's soaking path into Mexico

NASA's Aqua satellite provided infrared data on Tropical Depression Hanna while imagery from NASA-NOAA's Suomi NPP satellite was used to create an animation showing its movement from Texas to Mexico. Infrared data can reveal the location of powerful storms that generate heavy rainfall and Hanna drenched Texas upon landfall over the weekend of July 25-26.

Pristine environments offer a window to our cloudy past

A new study uses satellite data over the Southern Hemisphere to understand global cloud composition during the industrial revolution. This research tackles one of the largest uncertainties in today's climate models -- the long-term effect of tiny atmospheric particles on climate change.

Controlling streams of liquid metal at room temperature

Researchers from North Carolina State University have demonstrated a technique that allows them to produce streams of liquid metal at room temperature. By applying a low voltage to the liquid metal, the researchers were able to tune its surface tension across at least three orders of magnitude.

Grape pips reveal collapse of ancient economy in the grip of plague and climate change

A team of archeologists from Bar-Ilan University and the University of Haifa has discovered new and compelling evidence for a significant economic downturn on the fringe of the Byzantine Empire in the aftermath of a major pandemic in the mid-sixth century CE. The research reconstructs the rise and fall of commercial viticulture in the middle of Israel's arid Negev desert using evidence about life...

Unprecedented look into 'central engine' powering a solar flare

Researchers have presented a new, detailed look inside the 'central engine' of a large solar flare accompanied by a powerful eruption by the Owens Valley Solar Array. The new findings offer the first measurements characterizing the magnetic fields and particles at the heart of the explosion.

Lithium in drinking water linked with lower suicide rates

Naturally occurring lithium in public drinking water may have an anti-suicidal effect - according to a new study. The study collated research from around the world and found that geographical areas with relatively high levels or concentration of lithium in public drinking water had correspondingly lower suicide rates.

Stopping listeria reproduction 'in its tracks'

Listeria contaminations can send food processing facilities into full crisis mode with mass product recalls, federal warnings and even hospitalization or death for people who consume the contaminated products. Researchers have discovered a chemical compound that stops listeria reproduction in both light and dark conditions which could lead to bacterial control in food products.
