Chinese spice provides insight into how human brains detect and perceive touch New insight into how human brains detect and perceive different types of touch, such as fluttery vibrations and steady pressures, has been revealed by UCL scientists with the help of the ancient Chinese cooking ingredient, Szechuan pepper. Humans have many different types of receptor cells in the skin that allow us to perceive different types of touch. For more than a century, scientists have puzzled over whether tou...

People with combined vision and hearing loss are nearly four times more likely to experience depression and more than three times more likely to suffer chronic anxiety, according to a new study published in the journal Frontiers in Psychology and led by Anglia Ruskin University..

Scientists warn not all tree planting is good! Several tree-planting initiatives do not increase carbon capture and could lead to negative impacts on biodiversity, landscapes and livelihoods, according to new research Image: Shutterstock As we grow up, we learn that trees are good for the environment due to their ability to act as a physical filter trapping dust and absorbing air pollutants, including carbon dioxide from the air. But what if the longest living species on Earth are not as good ...

New model explains controversies over saturated fats and heart disease risk In science, sometimes a new perspective can turn our interpretation of the data upside-down, and necessitate a paradigm shift. There has been, and continues to be, fierce disagreements in nutrition science as to what constitutes a healthy diet. A key controversy is the role of saturated fats in health and disease. Saturated fats are known to increase blood cholesterol levels, and increased blood cholesterol is often obs...

Study: COVID-19 is dangerous not only for the elderly but for middle-aged adults COVID-19 has been spreading rapidly over the past several months, and the U.S. death toll has now reached 400,000. As evident from the age distribution of those fatalities, COVID-19 is dangerous not only for the elderly but for middle-aged adults, according to a Dartmouth-led study published in the European Journal of Epidemiology. For a person who is middle-aged, the risk of dying from COVID-19 is about 100 times...

A single genetic test can identify the presence and cause of mismatch repair deficiency Researchers have developed a new integrated genetic/epigenetic DNA-sequencing protocol known as MultiMMR that can identify the presence and cause of mismatch repair (MMR) deficiency in a single test from a small sample of DNA in colon, endometrial, and other cancers. This alternative to complex, multi-step testing workflows can also determine causes of MMR deficiency often missed by current clinical tests. T...

Simple vision tests can predict Parkinsons dementia before it begins Simple vision tests can predict which people with Parkinsons disease will develop cognitive impairment and possible dementia 18 months later, according to a new study by UCL researchers. The study, published in Movement Disorders, adds to evidence that vision changes precede the cognitive decline that occurs in many, but not all, people with Parkinsons. In another new study published today in Communications Biology, the same...
