Early menstruation increases the likelihood of hot flushes and nights sweats decades later at menopause, according to a University of Queensland study. School of Public Health researchers analysed data from more than 18,000 middle aged women across the UK, USA and Australia, as part of the Life course Approach to reproductive health and Chronic […]

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body. MIT and Harvard University […]

The inflammatory molecule interleukin-17A (IL-17A) triggers immune cells that in turn reduce IL-17A’s pro-inflammatory activity, according to a study by the National Eye Institute (NEI) researchers. In models of autoimmune diseases of the eye and brain, blocking IL-17A increased the presence of other inflammatory molecules produced by Th17 cells, immune […]

Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother. While the embryo is still a single cell, the maternal cells surrounding it deposit certain proteins inside it at specific locations. This establishes protein gradients that direct the […]

Don’t use it, lose it. This old saying applies to so many areas of life, but also your mental capacity. You need to stimulate your brain in order to protect your cognitive ability from the horrors of aging. And you know what stimulates brain? Human contact – a new UCL-lead […]

Many people with autism experience sensory hypersensitivity, attention deficits, and sleep disruption. One brain region that has been implicated in these symptoms is the thalamic reticular nucleus (TRN), which is believed to act as a gatekeeper for sensory information flowing to the cortex. A team of researchers from MIT and […]

About 40 percent of children around the globe suffer from anemia because they do not consume enough iron. Now, studies by ETH researchers show that iron deficiency also reduces the protection provided by vaccinations. Despite the fact that global immunization programs are now reaching more people than ever, about 1.5 […]

Normal brain development occurs in part through a process called histone methylation, which controls the expression of the genetic code written in DNA. One of these histones, called H3K4me, is found extensively throughout the brains of mammals, including humans. Errors in the methylation of H3K4me can cause neurodevelopmental disorders and […]

The aberrant buildup of misfolded proteins is a hallmark of a host of disorders, including neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Aggregates of these toxic proteins wreak havoc on the function of cells, tissues, and organs, and despite intensive research over many decades, there are still no effective means […]

Some of the most promising advances in cancer treatment have centered on immunotherapies that rev up a patient’s immune system to attack cancer. But immunotherapies don’t work in all patients, and researchers have been searching for ways to increase their effectiveness. Now, researchers at Washington University School of Medicine in […]

Tel Aviv University researchers have found that the short time period around tumor removal surgery (the weeks before and after surgery) is critical for the prevention of metastases development, which develops when the body is under stress. According to the researchers, patients require immunotherapeutic treatment as well as treatment to […]

A research team from Tel Aviv University's Zimin Institute for Engineering Solutions Advancing Better Lives, led by Prof. Noam Shomron and doctoral student Artem Danilevsky, has developed a method to detect cancer cells in the abdominal cavity in real-time. Following a tumor removal surgery in the abdominal cavity, the team can detect whether all cancer […]

There’s no doubt that you can lose fat by eating less or moving more—yet after decades of research, the biology underlying this equation remains mysterious. What really ignites the breakdown of stored fat molecules are nerves embedded in the fat tissue, and a new study now reveals that these fat-burning […]

Fighting cancer often means employing a suite of techniques to target the tumor and prevent it from growing and spreading to other parts of the body. It’s no small feat — the American Cancer Society predicts roughly 1.8 million new cases of cancer in the country in 2020, underscoring the […]

Scientists from the Vaccine and Infectious Disease Organization-International Vaccine Centre (VIDO-InterVac) at the University of Saskatchewan (USask) and Temple University in Philadelphia, Penn., have demonstrated that a salmonella biofilm protein can cause autoimmune responses and arthritis in animals.
