Milagro detects cosmic ray hot spots
The University of Maryland-led Milagro collaboration, comprised of scientists from 16 institutions across the United States, has discovered two nearby regions with an unexpected excess of cosmic rays.    view more (2008-11-25)

Light pollution offers new global measure of coral reef health
We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl.   view more (2008-11-25)

Los Alamos Observatory Fingers Cosmic Ray 'Hot Spots'
A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays. The research calls into question nearly a century of understanding about galactic magnetic fields near our solar system.    view more (2008-11-24)

Anthropologist Discovers Long-Lost Primate
A team led by a Texas A&M University anthropologist has discovered a group of primates not seen alive in 85 years.    view more (2008-11-19)

Astronomers detect matter torn apart by black hole
Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the centre of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense... view more (2008-11-19)

New national survey says public reveres bison
Americans are woefully out of touch with the fact that the American bison, or buffalo, is in trouble as a wild, iconic species, but they do love them as an important symbol of their country-and as an entrée on the dinner table.   view more (2008-11-19)

NSF / NASA 'Firefly' CubeSat Mission to Study Link Between Lightning and Terrestrial Gamma Ray Flashes
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected... view more (2008-11-18)

APEX reveals glowing stellar nurseries
Illustrating the power of submillimetre-wavelength astronomy, an APEX image reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimetre light is the key to... view more (2008-11-12)

Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days.   view more (2008-11-06)

West Nile's North American spread described
The rapid spread of West Nile virus in North America over the past decade is likely to have long-lasting ecological consequences throughout the continent, according to an article in the November issue of BioScience.   view more (2008-11-03)

The NASA/ESA Hubble Space Telescope is back in business
Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147.   view more (2008-10-31)

Studies of small water fleas help ecologists understand population dynamics
A study of populations of tiny water fleas is helping ecologists to understand population dynamics, which may lead to predictions about the ecological consequences of environmental change.   view more (2008-10-31)

EPA teams with National Geographic Society and World Resources Institute to map ecosystem services
The U.S. Environmental Protection Agency (EPA) is collaborating with the National Geographic Society and the World Resources Institute to develop tools that will help to fully account for the value of ecosystem services.   view more (2008-10-30)

Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the... view more (2008-10-28)

Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science.    view more (2008-10-24)

Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous... view more (2008-10-21)

Current mass extinction spurs major study of which plants to save
The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say.   view more (2008-10-21)

Colossal Black Holes Common in the Early Universe
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and... view more (2008-10-17)

New comet discovered in Canada
Rob Cardinal was looking for an asteroid, but ended up finding a comet. It is the first time a comet has been discovered at the University of Calgary's Rothney Astrophysical Observatory, which is located about 35 kilometres southwest of Calgary, and only the second Canadian discovery of a comet... view more (2008-10-15)

Fitness in a Changing World
The stickleback fish, Gasterosteus aculeatus, is one of the most thoroughly studied organisms in the wild, and has been a particularly useful model for understanding variation in physiology, behavior, life history and morphology caused by different ecological situations in the wild.   view more (2008-10-13)

Smithsonian perspective: Biodiversity in a warmer world
Will climate change exceed life's ability to respond? Biodiversity in a Warmer World, published in the Oct. 10, 2008 issue of the journal, Science, illustrates that cross-disciplinary research fostered by the Smithsonian Tropical Research Institute in Panama clearly informs this urgent debate.   view more (2008-10-10)

Ecological restoration as a tool for reversing ecosystem fragmentation
Ecosystem fragmentation, along with many other global trends, is causing the natural world to undergo profound changes at all spatial scales from the micro-habitat to the continental.   view more (2008-10-09)

Oklahoma researchers support biodiversity in biofuels production
U.S. and European mandates for subsidies of cellulosic ethanol production and use have uncertain environmental consequences according to an international group of scientists which includes researchers from the University of Oklahoma and Oklahoma State University.   view more (2008-10-06)

Shift in bald eagle diet linked to sea otter decline
A newly published study has found that the decline of sea otters along Alaska's Aleutian Islands has forced a change in the diet of a terrestrial predator - the bald eagle. The study demonstrates the extraordinary complexity of marine ecosystems and how far-ranging the impacts can be when there is... view more (2008-10-03)

Common insecticide can decimate tadpole populations
The latest findings of a University of Pittsburgh-based project to determine the environmental impact of routine pesticide use suggests that malathion--the most popular insecticide in the United States--can decimate tadpole populations by altering their food chain, according to research published... view more (2008-09-30)
