Study of nearly 2,000 Marine recruits reveals asymptomatic SARS-CoV-2 transmission

A study of nearly 2,000 Marine recruits who went through supervised quarantine before starting basic training revealed several instances of asymptomatic transmission of SARS-CoV-2, the virus that causes COVID-19, despite the quarantine measures. The findings have important implications for the effectiveness of public health measures to suppress transmission of COVID-19 among young adults, whether in […]

Study reveals role of sleep deprivation in unwanted thoughts

Lack of sleep significantly impairs our ability to stop unwanted and unpleasant thoughts from entering our mind, a new study reveals. The authors of the study say the findings could have implications for people suffering from psychiatric conditions associated with unwanted thoughts—such as post-traumatic stress disorder, depression and schizophrenia. The study, from the University of […]

Study reveals most effective drugs for common type of neuropathic pain

More than 20 million people in the U.S. suffer neuropathic pain. At least 25% of those cases are classified as unexplained and considered cryptogenic sensory polyneuropathy (CSPN). There is no information to guide a physician’s drug choices to treat CSPN, but a researcher from the University of Missouri School of Medicine and MU Health Care […]

Genetic study reveals ancestry-specific risk factors for coronary artery disease

A large team of researchers affiliated with a host of institutions across Japan has identified multiple loci associated with ancestry-specific risk factors for coronary artery disease. In their paper published in the journal Nature Genetics, the group describes their analysis of genetic information from several publicly available databases and its results. Coronary artery disease is […]

Study reveals design flaws of chatbot-based symptom-checker apps

Millions of people turn to their mobile devices when seeking medical advice. They’re able to share their symptoms and receive potential diagnoses through chatbot-based symptom-checker (CSC) apps. But how do these apps compare to a trip to the doctor’s office? Not well, according to a new study. Researchers from Penn State’s College of Information Sciences […]

New study reveals why flu can be devastating for pregnant women

New research helps explain why flu can lead to life-threatening complications during pregnancy, suggesting the virus does not stay in the lungs but spreads throughout the mother’s body. The pre-clinical study has overturned current scientific thinking on the reasons why flu infections affect pregnant women and their babies so severely. The findings could also help […]

Touch-and-know: Brain activity during tactile stimuli reveals hand preferences in people

Have you ever wondered whether the brains of right-handed people work differently from those of left-handers? Is it possible to distinguish between them by observing their brain activity in response to stimuli or tasks? These are important questions from the perspectives of both basic sciences and application-based fields such as brain-computer interfaces, rehabilitation robotics, and […]

Baby heartbeat reveals the stress of having a depressed or anxious mother

Scientists have shown that the babies of mothers dealing with anxiety or depression exhibit physiologically stronger signs of stress than babies of healthy mothers, when given a standard stress test. These babies show a significantly increased heart rate, which researchers fear may lead to imprinted emotional stresses as the child grows up. The interaction of […]

Imagery reveals autism-related brain differences

People with autism spectrum disorder have lower levels of a protein that regulates the amount of serotonin in the brain, a paper from Karolinska Institutet in Sweden published in the journal Molecular Psychiatry reports. For their study, the researchers used a molecular brain imaging technique to compare people with and without autism; their results offer […]
