Loss of pollinating species could put global crops at risk, increase malnutrition levels. Problem is especially acute in some developing countries, researchers say.
NASA launched rockets from Alaska into the Northern Lights to study upper atmosphere turbulence. Vapor trails released by the rockets will help researchers photograph and visualize atmospheric movement.
Severe neglect in childhood can cause structural changes in the brain that can hinder development, a study finds. However, early intervention could prevent or even repair such damage, researchers suggest.
President Obama want $1.2 billion to fight antibiotic-resistant infections that kill some 23,000 American each year. Growth of antibiotic resistance could turn treatable infections into life-threatening ones, experts warn.
If the giant ring system around a distant exoplanet were around Saturn instead, it would be visible from Earth to the naked eye, astronomers say. Giant system of at least 30 rings spans almost 100 million miles, they say.
Heavy use of certain non-prescription drugs could increase risk of Alzheimer's and other kinds of dementia, study suggests. Popular drugs to treat insomnia, hay fever, depression linked to increased risk, researchers say.
As flu hits hard this winter, researchers continue search for a "one and done" lifetime vaccination. Clinical trials on one candidate are to begin soon.
U.S. pediatric group calls for loosening restrictions on marijuana to allow medical uses in youngsters. While still opposing complete legalization, American Academy of Pediatrics calls for allowing "compassionate use" for extremely ill children.
LightSail spacecraft will use sunlight as power by unfurling four large sails to catch and reflect photons in sunlight, its developers say. Tiny spacecraft, just a foot long, can extend giant sails on 13-foot extendable booms.
Scientists say research could yield a way to stop the deterioration of our chromosomes that comes with aging. Findings could mean new treatments for aging-related diseases, they say.
Hubble turns it eyes on the Andromeda Galaxy to capture the highest-resolution image ever taken of space. 1.5 billion pixels make up the image, which would need 750 high-def TV screens to view in its entirety at full size.
Trying to remember a bunch of facts and figures for tomorrow's exam? You brain might do a better job of it if you're asleep than if you stay awake, researchers suggest.
Hoping to catch a glimpse of the next asteroid to zip past the Earth? A small telescope or even a good pair of binoculars could give you a ring-side seat, astronomers say.
Auction of private collection of Lincoln memorabilia brings more than $800,000 at Dallas Auction. Many items had links to Lincoln's assassin, John Wilkes Booth.
"Unboiling" an egg may seem pointless, but it could have a dramatic impact in biotechnology, researchers say. It's all to do with proteins and how they form and re-form, they say.
NASA spacecraft starts a photographic record of its approach to the dwarf planet at the edge of the solar system. New Horizons spacecraft will make its closest approach to Pluto in July.
Scientists identify some genes involved in the formation of long-term memories. Finding may help discover why loss of long-term memories often occurs in old age, researchers say.
Video therapy to help parents learn how to respond to their infant's communication style could lessen symptoms of autism in high-risk babies, study shows. Such intervention in the first year of life could have significant benefits later on, researchers say.
Researchers develop a material that can bend and control acoustic or elastic waves. Discovery could have applications in many fields and numerous kinds of devices, they say.
Global warming could drive living corals on Australia's Great Barrier Reef to dangerously low levels, study suggests. Health of the reef, a World Heritage Site, of great concern with rising ocean temperatures, researchers say.
Loss of large trees in California makes state forests more susceptible to wildfires, researchers say. Decline in larger trees could also have an impact on the global carbon cycle, they add.
Human-like hands predate actual humans on our evolutionary family tree, study suggests. Hand bones seen in early ape-like ancestors suggest the ability to hold, use tools, researchers say.
Time-lapse video gives startling evidence of the effect warming is having on Arctic sea ice. Video shows almost 3 decades of shrinking ocean ice cover.
Sun-watching space telescope has been snapping images of the sun and an amazing clip for 5 years. Data helps scientists understand solar flares and space weather that can threaten Earth.
