A new study by researchers at the University of California, San Diego, and Emory University has uncovered fundamental details about the hexamer structures that make up the tiniest droplets of water, the key component of life – and one that scientists still don't fully understand.

Two tropical cyclones were spotted from NOAA's GOES-15 satellite today, August 15. Tropical Storm Hector continues to weaken in the Eastern Pacific Ocean, while the remnants of the Atlantic Ocean's Tropical Depression 7 are moving over Central America. NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md., uses the GOES-15 satellite data to create images and animations from the satellite. The NOAA GOES-15 satellite sits in a fixed orbit over the eastern U.S. and provides infrared and visible imagery of the Eastern Pacific Ocean basin continuously.
Taking oral contraceptives continuously, rather than as traditionally prescribed for each cycle, provides earlier relief for moderate to severe menstrual cramps -- dysmenorrhea -- according to researchers at Penn State College of Medicine.
Dysmenorrhea occurs during menstruation, resulting from abnormal uterine contractions, increased sensitivity to pain and added pressure in the pelvic area. It is often accompanied by nausea, vomiting, diarrhea, headache and fatigue.
DURHAM, N.H., August 15, 2012 – A new report by U.S. and Canadian scientists analyzes decades of research and concludes that the climate of the Northeast has changed and is likely to change more. The report outlines the effects of climate change on multiple aspects of forests in the northeastern corner of the United States and eastern Canada and concludes with recommendations on adaptive and mitigating strategies for dealing with future effects.
NOAA-led paper published today in the journal Conservation Biology, high levels of background noise, mainly due to ships, have reduced the ability of critically endangered North Atlantic right whales to communicate with each other by about two-thirds.
CAMBRIDGE, Mass. — When you look at a gift-wrapped present, the basic properties of the wrapping paper — say, its colors and texture — are not generally changed by the nature of the gift inside.
A new discovery should make the alternative fuel butanol more attractive to the biofuel industry. University of Illinois scientist Hao Feng has found a way around the bottleneck that has frustrated producers in the past and could significantly reduce the cost of the energy involved in making it as well.
Scientists taking advantage of the versatility and new capabilities of the Relativistic Heavy Ion Collider (RHIC), an atom smasher at the U.S. Department of Energy's Brookhaven National Laboratory, have observed first glimpses of a possible boundary separating ordinary nuclear matter, composed of protons and neutrons, from the seething soup of their constituent quarks and gluons that permeated the early universe some 14 billion years ago.
Soil microbes are impulsive. So much so that they help plants face the challenges of a rapidly changing climate.
Ariz. – Earthquakes are among the most destructive and common of geologic phenomena. Several million earthquakes are estimated to occur worldwide each year (the vast majority are too small to feel, but their motions can be measured by arrays of seismometers). Historically, most of Arizona has experienced low levels of recorded seismicity, with infrequent moderate and large earthquakes in the state.
A fractured skull and a thigh bone hacked in half -- finds of damaged human bones along with axes, spears, clubs and shields confirm that the bog at Alken Enge was the site of violent conflict
'It's clear that this must have been a quite far-reaching and dramatic event that must have had profound effect on the society of the time,' explains Project Manager Mads Kähler Holst, professor of archaeology at Aarhus University.
Emissions from shipping have sharply decreased in EU ports, and politicians are giving thanks to an EU policy which limits sulfur content in fuels for ships at berth or at anchor in ports rather than wrecking their economy, which has led to fewer goods being shipped at all.
During serious flooding around Manila and major rice-growing across Luzon in the Philippines, some good news has emerged for rice farmers – Submarino rice – rice that can survive around 2 weeks of being under water.
Rice is unique because it can grow well in wet conditions where other crops cannot, but if it is covered with water completely it can die, leaving flooded farmers bereft of income.
When a hurricane's path carries it over large areas of fresh water, it will potentially intensify 50 percent faster than those that do not pass over such regions, meaning it has greater potential to become a stronger storm and be more devastating, according to a study co-written by a group of researchers at Texas A&M University.
