You know that dizzy feeling you get when, after lying down for an extended period, you stand up a little too quickly? That feeling is caused by a sudden reduction of blood flow to the brain, a reduction of around 30 percent. Now imagine living every minute of every day […]

Human body is very adaptable to various changes that occur during your lifetime. You notice that when some functions of your body become impaired. For example, those who lose limbs learn o get around without them very quickly. Now scientists from UCL and the University of Oxford found that detailed […]

When metastatic cancer cells need to avoid a threat, they simply reprogram themselves. Rice University scientists are beginning to get a handle on how they survive hostile environments. Members of Rice’s Center for Theoretical Biological Physics (CTBP) and cancer metabolism researchers at Baylor College of Medicine have created a basic framework of […]

People who inherit a faulty copy of the so-called “breast cancer genes” BRCA1 and BRCA2 are at high risk of cancer. About 10 percent of breast cancer cases and 15 percent of ovarian cancers can be traced back to a flaw in one of these genes. A class of drugs known as PARP inhibitors […]

Researchers have found that treating psoriasis, a chronic inflammatory skin disease, with biologic drugs that target immune system activity can reduce the early plaque buildup that clogs arteries, restricts blood flow, and leads to heart attacks and stroke. The findings highlight how immunotherapies that treat inflammatory conditions might play a […]

Research from the University of Pittsburgh School of Medicine in animal models and patient tissues has identified a new molecular pathway in the liver that suggests a commonly used anti-rejection medication could be repurposed to treat certain liver cancers. “What we’ve found is that liver cancers with a specific mutation in the […]

Tissues and organs in the human body are shaped through forces generated by cells, that push and pull, to “sculpt” biological structures. Thanks to a new tool developed at McGill University, scientists will now be able to watch, and map these forces. Christopher Moraes, an assistant professor in McGill’s Department […]

The production of sperm — otherwise known as spermatogenesis — generates more than 1,000 sperm per second in normal males. This productivity comes, in part, from a special cell type called the spermatogonial stem cell. The staying power of this stem cell has allowed many celebrities, including Robert DeNiro and […]

MicroRNAs can weaken cancer cells in advance of standard therapy in preclinical models, study shows. In the quest for new cancer therapies, microRNAs—tiny strings of nucleotides churned out inside cells—have been a source of both excitement and disappointment. While preclinical studies have found that microRNAs play an important role in […]

Researchers have discovered how specific cells in the guts of mice slow down metabolism and eventually contribute to obesity, diabetes, hypertension and atherosclerosis. The findings, scientists say, could have important implications for the prevention and treatment of these kinds of metabolic diseases in humans. The study was funded by the […]

A new study reveals that approximately 1 in 5 individuals may experience mental health symptoms up to six months after mild traumatic brain injury (mTBI), suggesting the importance of follow-up care for these patients. Scientists also identified factors that may increase the risk of developing post-traumatic stress disorder (PTSD) and/or […]

An international team of researchers has identified a gene responsible for the onset of pigmentary glaucoma, which may lead to new therapies for the condition. “People who traditionally we wouldn't think of having glaucoma—young males in their 20s and 30s—are at particular risk for this form of the disease and […]
