New findings in mice indicate that scratching causes the brain to release serotonin, which intensifies the itch sensation. The same vicious cycle of itching and scratching is thought to occur in humans, and the research provides new clues that may help break that cycle, particularly in people who experience chronic itching.
Researchers have presented new evidence that capsaicin, the compound that gives chili...
Researchers have developed the first genetic strain of mice that can be infected with Ebola and...
Researchers say that by using nanotechnology, they have improved how a peptide can be delivered to the diseased heart tissue of mice.
A study has identified a potential target for therapies to treat cocaine addiction. Investigators fond evidence that changing one amino acid in a subunit of an important receptor protein alters whether cocaine-experienced animals will resume drug seeking after a period of cocaine abstinence.
Over the past decade, China has poured money into research, especially in the biomedical sciences. But as the nation’s health-care costs have risen in the past few years, critics have argued that the investment has not paid off. A group of researchers and government officials now hopes to improve those returns with the official opening of the National Centre for Translational Medicine in Shanghai.
Fluorescent fruit flies have helped researchers take a critical step toward understanding the human brain’s neuronal “wiring” and how it can go awry.
Scientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory — creating an unprecedented tool for researching the development and diseases of an organ central to several public health crises, ranging from cancer to diabetes.
The ability to pop a working copy of a faulty gene into a patient’s genome is a tantalizing goal for many clinicians treating genetic diseases. Now, researchers have devised a new way to carry out this genetic sleight of hand.
A unique mouse model of Graves' disease, an autoimmune disorder that causes hyperthyroidism, and new research findings that may help improve the treatment of Graves' disease will be highlighted in oral and poster presentations at the 84th Annual Meeting of the American Thyroid Association in Coronado, California.
Glioma is a common name for serious brain tumors. Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers have shown that one and the same cell of origin can give rise to different types of glioma.
Heavy drinking during adolescence may lead to structural changes in the brain and memory deficits that persist into adulthood, according to an animal study.
Scientists have uncovered a major contributor to Huntington’s disease, a devastating progressive neurological condition that produces involuntary movements, emotional disturbance and cognitive impairment.
A new effort mapping 24-hr patterns of expression for thousands of genes in 12 different mouse organs — five years in the making — provides important clues about how the role of timing may influence the way drugs work in the body.
Researchers studied lipoproteins in Drosophila melanogaster and found that that the blood brain barrier is a main sensor to report the nutritional status, especially the lipid composition of consumed food to special neurons which in turn regulate Insulin release. Calories play a rather minor role in this process.
A study has revealed the underlying genetic factors that help repair skin lesions caused by psoriasis, which could engender new methods of controlling the lingering condition.
Difficulty in conceiving a child is a major challenge for one in seven heterosexual couples in America, especially for those over the age of 35. Now a new discovery could boost the chances of conception in women undergoing in vitro fertilization (IVF) treatments.
Do blood vessels that feed tumors differ from other blood vessels? Fourteen years ago, experiments designed to answer that question led to the discovery of several genes that are more active in tumor-associated blood vessels than in normal blood vessels. Research now reveals the normal function of one of those genes and suggests it could be a good target for anticancer drug therapy.
