In a study published in Aging Cell, researchers at the University of Wisconsin–Madison show that mice making too much of a human protein called AT-1 show signs of early aging and premature death, which are also symptoms of the human disorder progeria. Researchers were able to reverse the signs of accelerated […]

MIT chemical engineers have developed a new sensor that lets them see inside cancer cells and determine whether the cells are responding to a particular type of chemotherapy drug. The sensors, which detect hydrogen peroxide inside human cells, could help researchers identify new cancer drugs that boost levels of hydrogen […]

The fusion of a sperm cell with an egg cell is the very first step in the process that leads to new individuals in sexually reproducing species. Fundamental as this process may be, scientists are only now beginning to understand the complexities of how it works. In a paper published […]

Researchers at University of California San Diego School of Medicine report that they have successfully created spinal cord neural stem cells (NSCs) from human pluripotent stem cells (hPSCs) that differentiate into a diverse population of cells capable of dispersing throughout the spinal cord and can be maintained for long periods […]

A koala virus could help researchers explain millions of years of accumulated ‘junk’ DNA in the human genome. An international team of researchers – including scientists from The University of Queensland – is studying a virus infecting koalas in the hope it could demonstrate how viruses have altered the DNA […]

When Joan Jorgensen was an undergraduate at the University of Wisconsin–Madison, her roommate confided that she had just one period before going through menopause in high school. Doctors told Jorgensen’s roommate that she would never have biological children. “This is devastating news at any age, let alone a high school […]

In the treatment of cancer, chemotherapy is a cleaver, not a scalpel. By attacking rapidly dividing cells, chemotherapy effectively fights tumors, but it also ravages healthy cells in the gut, bone marrow, the scalp and other organs, leading to severe side effects. These toxic chemicals save lives, but at a […]

Hookworms infect nearly 430 million people in the world, mostly in countries where sanitation is poor, and people often walk barefoot. The body’s immune system is critical to attacking the hookworm, resulting in damage to the body’s tissues. But just how this damage takes place — and what helps repair […]

Key aspects of the ageing of human cells can be reversed by new compounds developed at the University of Exeter, research shows. In a laboratory study of endothelial cells – which line the inside of blood vessels – researchers tested compounds designed to target mitochondria (the “power stations” of cells). In […]

A correlation between obesity and genetics has been found to be modified by diet, according to a scientific paper in the American Journal of Clinical Nutrition. A research group led by a U.S. Department of Agriculture (USDA) scientist found that a specific gene—APOA2—can result in a higher body mass index (BMI). […]

A University of Adelaide scientist and leading Adelaide surgeon is developing an early detection test for a deadly cancer and has today received a funding boost from the Ovarian Cancer Research Foundation (OCRF). Professor Martin Oehler, Clinical Professor of Obstetrics and Gynaecology at the University’s Robinson Research Institute and Director of Gynaecological […]

Symptoms of Parkinson’s disease include tremor, loss of smell and neuropsychiatric problems. However, many people aren’t diagnosed until their disease is well-advanced, which could limit their treatment options. Now, researchers have tested a sensor to detect early-stage Parkinson’s disease from the breath of patients. They report their results in ACS Chemical […]
