Researchers from the University of Gothenburg, Sweden, spend August in Sisimiut on the west coast of Greenland studying the prevalence of antibiotic resistance and the effects of antibiotic emissions on communities of bacteria living in marine sediments. More specifically, they were investigating how communities of bacteria in sediment and clay on the seabed are affected by exposure to antibiotics.

Three years ago University of Tennessee, Knoxville, researchers helped to discover water on the surface of the moon. Now, they are piecing together the origin of that water: solar wind.
A new study confirms solar wind as a source for water embedded in the lunar surface.
Solar wind is the continuous flow of charged particles from the sun. Scientists have speculated it to be responsible for water on the surface of the moon.
ANN ARBOR—The most likely source of the water locked inside soils on the moon's surface is the constant stream of charged particles from the sun known as the solar wind, a University of Michigan researcher and his colleagues have concluded.
Over the last five years, spacecraft observations and new lab measurements of Apollo lunar samples have overturned the long-held belief that the moon is bone-dry.
The very first tropical cyclone of the Southern Indian Ocean season has been born, and NASA's TRMM satellite captured an image of its rainfall.
On Oct. 12 at 1500 UTC (11 a.m. EDT), Tropical Cyclone 01S (TC01S) was "born" about 90 nautical miles (103.6 miles/166.7 km) west-southwest of Diego Garcia, near 8.3 South latitude and 70.6 East longitude. Diego Garcia is a coral atoll located in the south central Indian Ocean and is part of the British Indian Ocean Territory. It is about 1,970 nautical miles (3,650 km) east of Tanzania, Africa.
NASA measured light-to-moderate rainfall occurring throughout Typhoon Prapiroon, with just a small area of heavy rain near the storm's center is it tracks through the western North Pacific Ocean.
When NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Typhoon Prapiroon on Oct. 12 at 0741 UTC (3:41 a.m. EDT), the precipitation radar instrument detected light to moderate rainfall occurring over most of the storm at a rate between .78 to 1.57 inches/20 to 40 mm per hour. The northwestern quadrant of the storm had the lightest rainfall rate.
Tropical Depression 16 formed on Oct. 11 and by 5 p.m. EDT that same day, it strengthened into Tropical Storm Patty. NASA's TRMM and Terra satellite's captured imagery on Patty's rainfall intensity and cloud heights, both of which showed strong, high thunderstorms around the center of circulation.
The hottest and most massive stars don't live long enough to disperse throughout the galaxy. Instead, they can be found near the clouds of gas and dust where they formed -- and where they will explode as supernovae after a few million years. They huddle in tight clusters with other young stars or in looser groupings called OB associations, a name reflecting their impressive populations of rare O- and B-type stars.
SALT LAKE CITY, Oct. 11, 2012 – Using gravitational "lenses" in space, University of Utah astronomers discovered that the centers of the biggest galaxies are growing denser – evidence of repeated collisions and mergers by massive galaxies with 100 billion stars.
The 16th tropical depression of the Atlantic Ocean season has formed northeast of the Bahamas and NOAA's GOES-14 satellite captured a visible image of the storm as it tracks to the southwest.
As Typhoon Prapiroon slowed down and became quasi-stationary in the Philippine Sea NASA's Terra satellite passed overhead and captured an image of the storm.
NASA's Terra satellite passed over Typhoon Prapiroon on Oct. 11 at 0210 UTC (1010 p.m. EDT, Oct. 10) and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image of the storm. The visible imagery clearly showed a small ragged eye, and microwave satellite imagery confirmed the eye. Satellite imagery also confirmed a well-defined low-level center of circulation.
GAINESVILLE, Fla. — An unusual collaboration between researchers in two disparate fields resulted in a new discovery about the teeth of 65-million-year-old dinosaurs.
With the help of University of Florida mechanical engineering professor W. Gregory Sawyer and UF postdoctoral researcher Brandon Krick, Florida State University paleobiologist Gregory Erickson determined the teeth of hadrosaurs — an herbivore from the late Cretaceous period — had six tissues in their teeth instead of two. The results were published in the journal Science Oct. 5.
For anyone who has ever struggled while attempting to solve a Sudoku puzzle, University of Notre Dame researcher Zoltan Toroczkai and Notre Dame postdoctoral researcher Maria Ercsey-Ravaz are riding to the rescue. They can not only explain why some Sudoku puzzles are harder than others, they have also developed a mathematical algorithm that solves Sudoku puzzles very quickly, without any guessing or backtracking.
(Edmonton) A meteorite that landed in the Moroccan desert 14 months ago is providing more information about Mars, the planet where it originated.University of Alberta researcher Chris Herd helped in the study of the Tissint meteorite, in which traces of Mars' unique atmosphere are trapped.
"Our team matched traces of gases found inside the Tissint meteorite with samples of Mars' atmosphere collected in 1976 by Viking, NASA's Mars lander mission," said Herd.
RICHLAND, Wash. -- An increasing number of scientists are studying ways to temporarily reduce the amount of sunlight reaching the earth to potentially stave off some of the worst effects of climate change. Because these sunlight reduction methods would only temporarily reduce temperatures, do nothing for the health of the oceans and affect different regions unevenly, researchers do not see it as a permanent fix. Most theoretical studies have examined this strategy by itself, in the absence of looking at simultaneous attempts to reduce emissions.
Despite homeland security improvements since September 11, 2001, subway and rail commuters face higher risks of falling victim to terrorists and mass violence than frequent flyers or those engaged in virtually any other activity. And while successful criminal and terrorist acts against aviation have fallen sharply, those against subways and commuter trains have surged.
