A new study describes a new target and potential treatment for melanoma, the most dangerous form of skin cancer. MicroRNA can decide which genes in a cell's DNA are expressed and which stay silent. Melanoma tends to lack microRNA-26a, which makes the gene
Eating meals together as a family, even if only once or twice a week, increases children's daily fruit and vegetable intake to near the recommended five a day, according to researchers.
Malaria kills millions each year and gives medical researchers headaches because the mosquito-borne parasite that causes its deadliest form has developed resistance to every drug thrown at it. Now a molecular parasitologist reports a promising new low-cos
Researchers have pinpointed a molecular mechanism needed to unleash the heart's ability to regenerate, a critical step toward developing eventual therapies for damage suffered following a heart attack.
The memory of the human immune system is critical for the development of vaccines. Only if the body recognizes a pathogen with which it has already come into contact in the case of a second infection, the immune system can combat it more effectively than
New research examining the role of race and ethnicity in an individual's decision to become a donor for hematopoietic cell transplantation identifies several factors associated with varied participation rates in national donor registries across racial/eth
Even though there are many women who do not notice any special symptoms, there are some whose pre-menstrual disorders hamper their everyday lives: depressive mood, anxiety, excessive emotional sensitivity, fatigue, lack of concentration, headache, etc. Ne
Two recent experimental treatments — one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy — have been shown to produce long-term improvement in visual function in mouse models of retinitis pigme
One third of the world is infected with the bacterium that causes tuberculosis, a disease that is increasingly difficult to treat because of wide spread resistance to available drugs. Researchers have identified a fresh target to develop new drugs for TB.
A particular set of genes that interact with one another to regulate pain in humans has been identified. They found as well that differences in these genes may influence people's sensitivity to pain.

A researcher is looking closely at a molecule linked to aortic aneurysms in the abdomen, and her findings could lead to a treatment to reduce swelling of the aortic artery, which would be a life-saving treatment.
Growing new blood vessels in the lab is a tough challenge, but an engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.
Scientists have discovered that "random" mutations in the genome are not quite so random after all. Their study shows that the DNA sequence in some regions of the human genome is quite volatile and can mutate ten times more frequently than the r
Branch retinal vein occlusion -- blockage of the blood vessels that channel blood from the retina -- is a common eye disease. A type of blood clot in the eye, the disease causes reduced vision, and people with the disease also typically have an increased
Researchers are one step closer to understanding how embryos develop and grow while always keeping the same proportions between their various parts. Their findings, published today in Nature, reveal that scaling of the future vertebrae in a mouse embryo i
Over recent years, hospital-acquired Clostridium difficile infections have been a significant problem in UK hospitals and globally. There have been concerns that infections may be due to transmission between symptomatic patients, either directly, or indir
For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key question of biomedical research is how
