Electroconvulsive therapy (ECT), formerly known as electroshock therapy, involves inducing a brief seizure in the brain using controlled doses of electricity. While ECT is highly effective for certain mental illnesses, particularly depression, the reasons for its efficacy have long puzzled the fields of psychiatry and neuroscience. Now, researchers from University of California San Diego may have an answer. In two new studies published November 16, 2023 in Translational Psychiatry, they propose a new hypothesis that ECT alleviates depression symptoms by increasing aperiodic activity, a type of electrical activity in the brain that doesn’t follow a consistent pattern ...

A debate has broken out over whether Pfizer should have told pregnant women taking part in its maternal respiratory syncytial virus (RSV) vaccine trial that a trial of a similar GSK vaccine was stopped over a safety signal around preterm birth, an investigation by The BMJ can reveal. Pfizer’s vaccine, called Abrysvo, was recently approved for use in the US and the European Union, but is not yet authorised in the UK. Some experts have criticised Pfizer for not informing participants, while others believe notification would have been premature and caused unnecessary anxiety, reports freelance investigative journalist Hristio ...

As power generation from sources like solar and wind increases, along with the introduction of devices such as heat pumps and batteries, a new optimisation tool created at the University of Surrey will help the UK plan for a greener electricity network.   The researchers developed an algorithm to model how these smaller networks distributed electricity – factoring in how local grids could become unbalanced by adding too many heat pumps in a single area or generating more electricity than the grid could accept.   The Surrey team found that it was generally more efficient ...

The widespread adoption of nuclear power was predicted by computer simulations more than four decades ago but the continued reliance on fossil fuels for energy shows these simulations need improvement, a new study has shown.  In order to assess the efficacy of energy policies implemented today, a team of researchers looked back at the influential 1980s model that predicted nuclear power would expand dramatically. Energy policies shapes how we produce and use energy, impacting jobs, costs, climate, and security. These policies are generated using simulations (also ...

Strict embargo: 00.01 hrs GMT Thursday, 16th September, 2023    Every year 1.3 million lives are lost to cancers caused by smoking tobacco across the UK, US and BRICS nations (Brazil, Russia, India, China and South Africa), according to a new study, funded by Cancer Research UK.  Researchers found that together, the seven countries represented more than half of the global burden of cancer deaths every year. They concluded that smoking, as well as three other preventable risk factors – alcohol, overweight or obesity, and human papillomavirus (HPV) infections caused almost 2 million deaths combined.  The study, carried out ...

Pancreatic cancer is tricky to manage because it spreads easily and early, and the tumors have a unique biological makeup. But, researchers made a breakthrough by learning about the genetic changes that occur during tumor migration — and also found a drug that can obstruct the process. The next step is a groundbreaking clinical trial at the University of Rochester’s Wilmot Cancer Institute, planned for early in 2024, to test the drug from their laboratory discovery, said senior investigator Darren Carpizo, MD, PhD, co-leader of Wilmot’s Genetics, Epigenetics and Metabolism research program, and chief of Surgical Oncology at the University of Rochester Medical ...

The work was published Nov. 8 in Scientific Reports. The study adds to a growing body of research on the relationship between microbes and odor in mammals, including domestic dogs, wild animals such as foxes, pandas and hyenas, and humans. Cats’ scent comes ...

The advent of whole genome sequencing technology has prompted an explosion in research into how genetics are associated with disease risk. But the vast majority of genetics research has been done on people of European ancestry, and genetics researchers have realized that in order to address health disparities, more needs to be done. In a new study, Georgia Tech researchers investigated whether 25 rare gene variants known to be associated with inflammatory bowel disease (IBD) play a role in risk for African Americans. While the rare variant associations were recently discovered in individuals of European ancestry, ...

A new Kaiser Permanente physician peer support program designed to reduce burnout helped improve doctors’ well-being and had a positive impact on the culture of the medical departments that took part in the program, Kaiser Permanente researchers found.   The study, published November 1 in PLOS ONE, analyzed the impact of the Kaiser Permanente Northern California (KPNC) Peer Outreach Support Team (POST) program in 2 KPNC hospitals. POST is now active in 10 KPNC hospitals, and 3 more hospitals intend to launch POST programs over the next few months. Uniquely, the POST program allows for third-party referrals — ...

Even though they’re the largest animals on earth, whales remain difficult to track. So experts often turn to historical whaling data to inform current research. A dataset maintained by the International Whaling Commission (IWC) contains detailed information on commercial whale catches — more than 2.1 million records, predominantly from 1880 until the IWC banned whaling in 1986. Yet for researchers, distilling that data can prove its own challenge. A team at the University of Washington has created an online interactive map called WhaleVis, which lets whale researchers visualize ...

Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches led by Marissa Langager, a Ph.D. student in the Department of Biological Sciences in the College of Science, uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even ...

Macrophages, a type of white blood cell that can destroy invading pathogens, have an innate ability to infiltrate tumor cells, making them a potentially important tool in treatments that use transplanted cells to fight disease, known as cell therapy.  In the lab, macrophages show a lot of promise in treating cancer but so far, clinical trials have been a disappointment and biologists are trying to figure out why. But what if it’s not a biological problem? In a recent paper, researchers from the Harvard John A. Paulson School of Engineering and Applied ...

All aquatic species in the river mouths flowing into the Mediterranean Sea and Atlantic Ocean are contaminated with microplastics, with molluscs being the most affected due to their ability to filter water. Rivers are one of the main sources of pollution by microplastics (5 to 0.0001 mm in size) and nanoplastics (smaller than 0.0001mm) in the oceans. Estuaries, as transition zones between rivers and the sea, are major hotspots for the accumulation of these particles, which are retained in sediments. They pose a threat to aquatic ecosystems given their ability to capture harmful chemicals from the surrounding environment, ...

MINNEAPOLIS – With the rise of new drugs that can target the amyloid-beta plaques in the brain that are an early sign of Alzheimer’s disease, new ways are needed to determine whether memory loss and thinking problems are due to Alzheimer’s disease or another neurodegenerative disorder. A new study published in the November 15, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology, shows that shrinkage in the hippocampus area of the brain is associated with cognitive decline, even in people who don’t have amyloid plaques in the brain. The hippocampus plays a role in memory. “These results suggest ...
