Scientists at the University of York have developed a new technique that uses light to understand how cells communicate in human disease. All cells in the human body communicate with each other by releasing signalling molecules; this helps to ensure that tissues function normally, that the immune system is able to respond to infection, and that cell division and survival […]

The comment in question was posted on the popular Facebook page, Sanctimommy, and while the author remains unknown, her criticism does not. Just read. “Ladies, even if you aren’t getting out of the car at [school] drop off can you please try a little?” the unidentified woman writes. “I look around as I’m walking my daughter to the front door and […]

Some 80% of young people will experience a traumatic event by the time they become an adult. Rates of exposure to trauma peak during adolescence. The stress from traumatic events can result in a loss of interest in school, friends, hobbies, and life in general. The types of traumatic events include a wide range of terrifying and life-threatening experiences such […]

For most, the time spent staring at screens—on computers, phones, iPads—constitutes many hours and can often disrupt sleep. Now, Salk Institute researchers have pinpointed how certain cells in the eye process ambient light and reset our internal clocks, the daily cycles of physiological processes known as the circadian rhythm. When these cells are exposed to artificial light late into the […]

Science is only ever as good as the research that sits behind it. That means the methods we use to conduct science must be robust, repeatable and suitable to the questions we want to ask. When these questions become very complex – for instance, why are some groups of people more likely to get diabetes than others? – we need […]

For veterans struggling with post-traumatic stress disorder, service dogs might be able to offer both behavioral and physiological benefits to help counter some of those symptoms, according to research that is being led by the Purdue College of Veterinary Medicine. Maggie O’Haire, assistant professor of human-animal interaction in the College of Veterinary Medicine, is at the forefront of the research […]

The internet can seem to be a big, scary place for parents, especially since children grow up with access practically from the moment they exit the womb. While the easiest thing to do is give a child a phone and call it a day, it’s important for parents to help guide their kids as they use the internet. Here are […]

One of the many challenges with battling alcohol addiction and other substance abuse disorders is the risk of relapse, even after progress toward recovery. Even pesky fruit flies have a hankering for alcohol, and because the molecular signals involved in forming flies’ reward and avoidance memories are much the same as those in humans, they’re a good model for study. […]

Researchers from the University of California, Irvine School of Medicine, have found that a rare gene mutation alters brain development in mice, impairing memory and disrupting the communication between nerve cells. They also show memory problems could be improved by transplanting a specific type of nerve cell into the brain. The findings were published today in Neuron. “Mutations in hundreds […]

Researchers have developed a new device that can be used to visualize how sound-induced vibrations travel through the ear. The technology is providing new insight into how the ear receives and processes sound waves and, with additional development, might one day be used by physicians to diagnose diseases that affect hearing. The new imaging tool is based on optical coherence […]
