Experts call for halt to CRISPR editing that allows gene changes to pass on to children

Remember the global outrage four months ago at world-first claims a researcher had used the gene editing tool CRISPR to edit the genomes of twin girls? The molecular scissors known as CRISPR (CRISPR/cas9 in full) allow scientists to modify DNA with high precision and greater ease than previous technologies. Now researchers from the USA, Europe, China and New Zealand have […]

Hookah smokers are inhaling toxic chemicals that may harm the heart

Smoking tobacco in waterpipes, more commonly known as hookahs, results in inhaling toxic chemicals, often at levels exceeding cigarette smoke, that may harm the heart and blood vessels, according to a new scientific statement published in the American Heart Association’s journal Circulation. Waterpipes go by many names—hookah, narghile, argileh, shisha and goza—and usually consist of a head or bowl that […]

Scientists identify genetic factors that may cause some people to become obese

Obesity is a major public-health problem in the United States and around the world, with an estimated 650 million people suffering from the condition. One of the biggest challenges of this ever-worsening condition is figuring out why people become obese in the first place, and why some people are more vulnerable to obesity than others. Now, scientists at The Rockefeller […]

We all sweat 'down there,' but there are things that help

Let’s face it, we all get a little sweaty while working out — and yes, that includes your vagina and vulva. Engaging in a legs-together workout such as running tends to cause the most amount of sweat in your groin and vaginal area, so it’s no wonder women experience this persistent problem. While vaginal wetness and odor can be slightly […]

Data show no evidence that teens’ social media use predicts depression over time

Longitudinal data from adolescents and young adults show no evidence that social media use predicts later depressive symptoms, according to research published in Clinical Psychological Science, a journal of the Association for Psychological Science. However, the findings do show that relatively higher depressive symptoms predicted later social media use among adolescent girls. This research stands in contrast with recent claims […]

Researchers identify faulty ‘brake’ that interferes with heart muscle’s ability to contract and relax

Hypertrophic cardiomyopathy (HCM) is the most common genetic disease of the heart and a leading cause of sudden cardiac death in young people and athletes. Scientists have long known that the condition’s cardinal feature—an unusually thick heart muscle that contracts and relaxes abnormally—is fueled by some glitch in the heart’s molecular machinery. Yet, the sparkplug that ignites such disordered muscle […]

A major new report has developed a global diet that could improve health and reduce further damage to the planet

An international team of researchers, including academics from City, University of London, has developed a new diet it says can improve health while ensuring sustainable food production. The EAT-Lancet Commission provides the first scientific targets for a healthy diet from a sustainable food production system that operates within planetary boundaries for food. The report sets out a ‘planetary health diet’ […]

Researchers discover the brain cells that make pain unpleasant

If you step on a tack, neurons in your brain will register two things: that there’s a piercing physical sensation in your foot, and that it’s not pleasant. Now, a team of scientists at Stanford University has identified a bundle of brain cells in mice responsible for the latter—that is, the negative emotions of pain. Pain research has traditionally focused […]

Muscle stem cells can drive cancer that arises in Duchenne muscular dystrophy

People with Duchenne muscular dystrophy (DMD) can develop an otherwise-rare muscle cancer, called rhabdomyosarcoma, due to the muscle cells’ continuous work to rebuild the damaged tissue. However, little is known about how the cancer arises, hindering development of a treatment or test that could predict cancer risk. Now, scientists from Sanford Burnham Prebys Medical Discovery Institute (SBP) have demonstrated that […]

Activated PMN exosomes are pathogenic entities that cause destruction in the COPD lung

University of Alabama at Birmingham researchers have found a novel, previously unreported pathogenic entity that is a fundamental link between chronic inflammation and tissue destruction in the lungs of patients with chronic obstructive pulmonary disease, or COPD. COPD is the fourth-leading cause of death in the world. This pathogenic entity—exosomes from activated polymorphonuclear leukocytes, or PMNs—caused COPD damage when the […]
