It is a terrible situation when your life depends on others. But that is how a lot of people awaiting organ transplant are feeling. They are carrying a huge weight on their shoulders, waiting for a matching donor. A lot of people die before a suitable donor is found. But […]

Researchers at the University of Oxford, working with colleagues in Erlangen, Germany and at the Cleveland Clinic, USA, have developed a new technology based on analysis of computed tomography (CT) coronary angiograms that can flag patients at risk of deadly heart attacks years before they occur. Heart attacks are usually […]

Obesity is associated with a host of health problems, including heart disease, type 2 diabetes and high blood pressure. According to a new study reported in the Journal of Physiology, obesity also diminishes a person’s ability to build muscle after engaging in resistance exercise. “Several previous studies, including some from […]

The nervous system is a complex network of neurons that coordinates the body by transmission of electrical signals. And just like the power lines that deliver electricity to homes and businesses, the nervous system sometimes needs maintenance. During early development, animals are constantly eliminating unnecessary neuronal material; the nervous systems […]

Researchers from the University of Zurich can, for the first time, precisely characterize the protein modification ADP-ribosylation for all proteins in a tissue sample. The changes, which are a typical reaction to stress, provide information about the condition of a cell. Together with the University Hospital Zurich, they are now […]

Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep — and that’s a good thing. Today, scientists report that an extract from the leaves may prevent wrinkles. The scientists had previously studied the […]

About 50,000 people in the U.S. are diagnosed annually with head, neck, nasal and oral cancers. Most are treated with radiation, and of those, 70-80 percent develop a painful and debilitating side effect called severe oral mucositis (SOM). While some drugs are available to treat SOM once it develops, none […]

Scientists have discovered that beluga whales and narwhals go through the menopause – taking the total number of species known to experience this to five. Aside from humans, the species now known to experience menopause are all toothed whales – belugas, narwhals, killer whales and short-finned pilot whales. Almost all […]

Losing just one night of sleep can have a negative impact on human metabolism at the tissue level, according to a study published last week. The findings may explain how long-term shift work and chronic sleep loss can impair metabolism and adversely affect human body composition. Previous studies have shown that the risk […]

More than 100 years ago, German Nobel laureate Paul Ehrlich popularized the “magic bullet” concept — a method that clinicians might one day use to target invading microbes without harming other parts of the body. Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still […]

Immune cells in the eye that developed in response to early exposure to bacteria are a key contributor to progressive vision loss from glaucoma, the second leading cause of irreversible blindness in the world, according to new research from Harvard Medical School, Massachusetts Eye and Ear and MIT. The findings, published […]

Researchers funded by the National Eye Institute (NEI) have reversed congenital blindness in mice by changing supportive cells in the retina called Müller glia into rod photoreceptors. The findings advance efforts toward regenerative therapies for blinding diseases such as age-related macular degeneration and retinitis pigmentosa. A report of the findings […]
