Were dinosaurs "warm-blooded" like present-day mammals and birds, or "cold-blooded" like present day lizards?
SANTA CRUZ, CA--Studies conducted in California and elsewhere provide support for the use of marine reserves as a tool for managing fisheries and protecting marine habitats, according to biologists
If a circadian rhythm is like an orchestra -- the united expression of the rhythms of millions of cells -- a common chemical may serve as the conductor, or at least as the baton.
Paleontologists from the University of California, Berkeley, and the Museum of the Rockies have wiped out two species of dome-headed dinosaur, one of them named three years ago -- with great fanfa
Blacksburg, Va. -- In the course of doing research on the mosquito-borne pathogens chikungunya virus (CHIKV) and o' nyong-nyong virus (ONNV), Virginia Tech researchers have discovered an inconvenient truth about an assay, strand-specific quantitative real-time PCR (ssqPCR), increasingly being used to detect and measure replicating viral RNA in infected cells and tissues.
DURHAM, N.C. -- Young men who voted for Republican John McCain or Libertarian candidate Robert Barr in the 2008 presidential election suffered an immediate drop in testosterone when the election results were announced, according to a study by researchers at Duke University and the University of Michigan.
AUGUSTA, Ga. -- Over-expressing a gene that lets brain cells communicate just a fraction of a second longer makes a smarter rat, report researchers from the Medical College of Georgia and East China Normal University.
The number of children being admitted to hospitals in England for short stays increased by 41 per cent between 1996 and 2006, according to research published in PLoS One today.
Washington, DC -- Researchers at Georgetown University Medical Center (GUMC) are voicing alarm that drugs to treat a wide variety of allergies, asthma and autoimmune diseases now in human clinical trials may errantly spur development of breast tumors.
After 15 years of research in the waters of the South Atlantic and Indian Oceans, scientists from the Wildlife Conservation Society, the American Museum of Natural History, and an international coalition of organizations have unveiled the largest genetic study of humpback whale populations ever conducted in the Southern Hemisphere.
Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified the genetic mechanisms involved in the formation and survival of L-form bacteria. Their findings are described in a study published October 6 in the journal PLoS ONE.
(PHILADELPHIA) Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases.
New research published this week clips the wings of Archaeopteryx. First found in Germany in the 1860's and dating to 150 million years ago, Archaeopteryx has long been considered the iconic first bird.
TALLAHASSEE, Fla. -- The raptor-like Archaeopteryx has long been viewed as the archetypal first bird, but new research reveals that it was actually a lot less "bird-like" than scientists had believed.
Serious hikers and backpackers tend to become supporters of
environmental and conservation groups while casual woodland tourists do
not, a new study says -- and a recent fall-off in strenuous outdoor
endeavors portends a coming decline in the ranks of conservation
backers.
