Biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome replication and may offer insights into the factors
Infection control experts have found that a combination of robot-like devices that disperse a bleaching agent into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bac
Congenital hyperinsulinism is a genetic condition where a baby's pancreas secretes too much insulin. It affects approximately one in 50,000 live births and in severe cases requires the surgical removal of all or part of the pancreas. Researchers are now u
A new study has found that an important branch of the immune system, in reaction to the development of atherosclerotic lesions, mounts a surprisingly robust anti-inflammatory T cell response that helps prevent the disease from progressing. The findings ma
Smoking cessation even a year prior to coronary artery bypass grafting (CABG) surgery does not fully normalize the changes smoking has made to the saphenous (leg) veins used for the surgery and may lead to later graft failure, according to a new study.
Researchers have identified three new genetic "hotspots" linked to colorectal cancer. These variants provide new insight into the biology of colorectal cancer -- and could represent new therapeutic targets for the disease.
Researchers have discovered that a key regulator of energy metabolism in cancer cells known as the AMP-activated protein kinase (AMPK) may play a crucial role in restricting cancer cell growth. AMPK acts as a "fuel gauge" in cells.
Using two successive pairs of specialized CT scans, a team of radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels.
An oncologist has used the electronic medical records data of more than 400 patients in a single-center study that is further exploring results from the National Lung Screening Trial (NLST) released in 2010.
Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state, and has been implicated in several diseases. Researchers have developed a unique approach to calpain inhibition by

An international team has identified a key enzyme in the reprogramming process that promotes malignant stem cell cloning and the growth of chronic myeloid leukemia (CML), a cancer of the blood and marrow that experts say is increasing in prevalence.
Many of the most common inpatient surgeries in the United States are performed electively. These surgeries are expected to significantly increase with the enactment of the Affordable Care Act. Medical researchers are now recommending the nation's health c
A new study finds that certain changes in retinal blood vessels provide an early warning of increased glaucoma risk. Using Blue Mountains Eye Study data, the researchers showed that patients who had abnormally narrow retinal arteries at baseline were also
Current thinking on how the Toxoplasma gondii parasite invades its host is incorrect, according to a new study describing a new technique to knock out genes. The findings could have implications for other parasites from the same family, including malaria,
A gun violence prevention expert and emergency medicine physician, believes broader criteria for background checks and denials on gun purchases can help prevent future firearm violence, including mass shooting catastrophes such as those that occurred at S
Men and women with mental health disorders, across all diagnoses, are more likely to have experienced domestic violence than the general population, according to new research.
Scientists have sequenced the genome of the fungus Pneumocystis jirovecii, an advancement that could help identify new targets for drugs to treat and prevent Pneumocystis pneumonia, a common and often deadly infection in immunocompromised patients.
The causes of learning problems associated with an inherited brain tumor disorder are much more complex than scientists had anticipated, researchers report.
Babies only hours old are able to differentiate between sounds from their native language and a foreign language, scientists have discovered. The study indicates that babies begin absorbing language while still in the womb, earlier than previously thought
