Scientists have identified chemical changes in the DNA of patients with Crohn’s disease that could help to screen people for the disease. These changes can be detected in blood samples, opening the door to a simple test for Crohn’s disease.
The TIM family of proteins that promotes virus entry into cells also has the ability to block the release of HIV and other viruses, researchers have found.
Cancer, while always dangerous, truly becomes life-threatening when cancer cells begin to spread to different areas throughout the body. Now, researchers have discovered that a molecule used as a communication system by bacteria can be manipulated to prevent cancer cells from spreading.
A large new study found that when post-menopausal women stop physical activity, their odds of developing breast cancer rise. But, the study also found that breast cancer risk drops surprisingly rapidly after exercise starts.
A virus and a zebrafish are helping scientists map the living brain. The model will help show how brain wiring is laid and how it functions.
Researchers have developed a new integrated approach to pinpoint the genetic “drivers” of cancer, uncovering eight genes that could be viable for targeted breast cancer therapy.
Scientists have, for the first time, grown a complex, fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory.
For the 2.2 million Americans battling glaucoma, the main course of action for staving off blindness involves weekly visits to eye specialists who conttol increasing pressure within the eye. Now, a tiny eye implant could enable patients to take more frequent readings from the comfort of home.
A Liberian doctor who was among three Africans to receive an experimental Ebola drug has died, the country's information minister said Monday, as a top U.N. delegation promised more help for countries battling the virulent disease during a visit to Sierra Leone.
The American Heart Association's first policy statement on electronic cigarettes backs them as a last resort to help smokers quit. The American Cancer Society has no formal policy but quietly took a similar stance in May.
To date, almost all studies of autism in children have used a single imaging technique to explore connectivity. None has been able to capture a robust picture of the brain abnormalities associated with autism— until now. Researchers are combining three imaging techniques and harnessing the best of each one.
Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development, according to a new study.
Two American aid workers have recovered from Ebola and left an Atlanta hospital, after weeks of intensive treatment in a special isolation unit. They were first two Ebola patients ever brought to the United States.
The federal government is finalizing new restrictions on hundreds of medicines containing hydrocodone, the highly addictive painkiller that has grown into the most widely prescribed drug in the U.S.
New research suggests a one-two punch could help battle polio in some of the world's most remote and strife-torn regions: Giving a single vaccine shot to children who've already swallowed drops of an oral polio vaccine greatly boosted their immunity.
The birth control pill significantly affects ovarian reserve— or the number of immature eggs in a woman’s ovaries— which can be a predictor of future fertility, according to a team in Denmark.
Research shows that nerves may play a critical role in stomach cancer growth and that blocking nerve signals using surgery or Botox (onabotulinumtoxinA) could be an effective treatment for the disease.
Scientists have discovered an area of the brain that could control a person’s motivation to exercise and participate in other rewarding activities, potentially leading to improved treatments for depression.
As people grow older, they often have difficulty falling asleep and staying asleep, and tend to awaken too early in the morning. Now, a new study helps explain why sleep becomes more fragmented with age.
Scientists who study tuberculosis have long debated its origins. New research shows that tuberculosis likely spread from humans in Africa to seals and sea lions that brought the disease to South America and transmitted it to Native people there before Europeans landed on the continent.
A newborn screening test for severe combined immunodeficiency (SCID) reliably identifies infants with this life-threatening inherited condition, leading to prompt treatment and high survival rates, according to a new study.
After nearly three weeks of treatment, the two American aid workers who were infected with the deadly Ebola virus in Africa have been discharged from an Atlanta hospital, officials said Thursday.
The enzyme phospholipase D (PLD) helps the influenza virus escape the immune response, and blocking it could lead to a new way to prevent the flu.
New work by scientists suggests that both major forms of diabetes, type 1 and type 2, are the result of the same mechanism - the formation of toxic clumps of a hormone called amylin.
Scientists have made it easier to predict both breast cancer relapses and responses to chemotherapy, through the identification of a unique gene, a new study shows.
