New research using mice reveals heavy alcohol use actually rewires brain circuitry, making it harder for alcoholics to recover psychologically following a traumatic experience.
The World Health Organization says a yellow fever booster vaccination given 10 years after the initial shot isn't necessary.
Malaria parasites can “talk” to each other– a social behavior to ensure the parasite’s survival and improve its chances of being transmitted to other humans.
A single injection of nanogel can maintain normal blood-sugar levels for an average of 10 days in mice with Type 1 diabetes.
African frogs once imported to laboratories and hospitals around the world may have carried with them a devastating fungal infection thought to be responsible for a rapid, global, decline in amphibians.
A deadly new respiratory virus related to SARS can apparently spread from person-to-person as health care workers fell ill after contact with infected patients in eastern Saudi Arabia.
Engineers have transformed bacterial cells into living calculators that can compute logarithms, divide and take square roots, using three or fewer genetic parts.
Scientists have finally recovered stem cells from cloned human embryos, a longstanding goal that could lead to new treatments for such illnesses as Parkinson's disease and diabetes.
Two fossil discoveries from the East African Rift reveal new information about the evolution of primates.
Scientists have discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.
Researchers have found that the key to purple bacteria’s light-harvesting prowess lies in highly symmetrical molecules.
Colorful vegetables are promoted as key to a healthy diet, but white vegetables, especially potatoes, shouldn't be forgotten.
Researchers are considering the brain’s superior ability to send electrical signals along massively parallel channels: if a supercomputer was like a brain it would learn, adapt, hypothesize and then suggest answers.
Tuber processing giant J.R. Simplot Co. asked the U.S. government to approve five varieties of biotech potatoes that resist browning and are designed to produce lower levels of potentially cancer-causing acrylamide when fried.
The government has prosecuted oil companies when birds drown in their waste pits, power companies when birds are electrocuted by their power lines but has never fined or prosecuted a wind-energy company when birds hit their fans.
New research has revealed that the evolution of the complex, weight-bearing hips of walking animals from the basic hips of fish was a much simpler process than previously thought.
New research finds that suicide, while strongly associated with psychiatric conditions, also correlates with environmental pollution.
The tiniest bones in the human body– the bones of the middle ear– could provide huge clues about our evolution and the development of modern-day humans.
Chinese scientists have revealed that the DNA methylome of sperm, not oocytes, will be inherited by offspring.
A finding of disrupted brain gene orchestration gives first direct evidence of circadian rhythm changes in depressed brains and opens door to better treatment.
Researchers have invented a method for repairing damaged peripheral nerves.
Scientists have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for the form of age-related heart failure that affects millions of Americans.
A new study looking at the genomes of more than 13,000 men identified four new genetic variants associated with an increased risk of testicular cancer.
Experiments unearthed clues about which protein signaling molecules are allowed into hollow, hair-like “antennae,” called cilia, that alert cells to critical changes in their environments.
A study of carnivorous plants shows that the large majority of noncoding DNA— which is abundant in many living things— may not actually be needed for complex life.
