UK seeks to stamp out 'cowboy' cosmetic procedures

Forty-five percent of dementia cases are potentially preventable, and simple lifestyle choices including exercise, diet and social connection all contribute to your risk score. But what if these risk factors were leaving chemical warning signs of decline in your brain—long before any symptoms of dementia played out?

An interdisciplinary team of scientists has developed a technology to decode immune cell communication. By measuring interactions between cells, the method offers insights into how the human body fights viral infections, how malfunctions can lead to autoimmune diseases and why immunotherapies work for some people but not others.

Pancreatic cancer begins in the pancreas, which is located behind the stomach. It is often difficult to detect early because symptoms typically appear only after the cancer has spread. As a result, it is usually diagnosed at an advanced stage, which complicates treatment. Michael Kendrick, M.D., a hepatobiliary and pancreas surgeon at Mayo Clinic, explains how minimally invasive surgery is speeding recovery.

As the global population ages, the number of people aged 65 and older is projected to rise significantly over the next 25 years. But while we're living longer, we're also becoming more socially divided by age. Age segregation is on the rise and fewer people are regularly interacting with those outside their own generation.

People living in the most advantaged areas of Australia tend to drink more alcohol. But people who live in the least advantaged areas suffer the most alcohol-related harms, such as dying from alcohol-related disease or from alcohol-related injuries.

In a collaborative effort, researchers have uncovered a novel link between gut microbiota-derived palmitic acid (PA) and increased thrombosis risk in cardiovascular disease (CVD).

Ten years ago, researchers discovered a small group of people who derive no pleasure from music, despite having normal hearing and the ability to enjoy other experiences or stimuli. The condition, "specific musical anhedonia," is caused by a disconnect between the brain's auditory and reward networks.

On a hot day in July 2022, Professor Jay Graham hit the beach with an iPad in hand. He and Meredith Klashman, a student in the UC Berkeley–UCSF Joint Medical Program, approached a number of women at Santa Cruz's Cowell Beach, asking them to join their study.

John A. Moran Eye Center researcher Adam Dubis, Ph.D., is part of a big leap forward for the use of artificial intelligence in eye care.

Hand mobility is often impaired after tendon injuries or as a result of strokes. In therapy, exoskeletons increasingly serve to support recovery. These devices fit over the hand like a second skeleton and can assist with controlled movements of the wrist and fingers.

Misperceptions about nicotine abound. Nicotine is not the main cancer-causing component in cigarettes; still, many believe it is. Nicotine makes cigarettes addictive; many people believe it does not.

Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in regions underneath such as the hippocampus. In a new study, a team of MIT scientists and engineers demonstrates a new microscope system capable of peering exceptionally deep into brain tissues to detect the molecular activity of individual cells by using sound.

The first paper from a multi-year clinical research study has been published in The Lancet Infectious Diseases. The article "Dynamics of endemic virus re-emergence in children in the USA following the COVID-19 pandemic (2022–2023): a prospective, multicentre, longitudinal, immunoepidemiological surveillance study," demonstrates how the approach can improve modeling to better predict future outbreaks.

The Davos Alzheimer's Collaborative (DAC) today announced the publication of a new paper in Nature Medicine, detailing a bold five-year strategy to address global brain health by strengthening health systems and scaling low cost, easy to use innovations. The paper, titled "Strengthening Africa's Brain Health and Economic Resilience," presents the rationale and roadmap behind the African-led and DAC coordinated 6 x 5 Plan: six pillars to accelerate brain health progress over the next five years.

As we age, the genes in our cells accumulate more mutations. This is one of the contributory factors to age-related diseases and the aging process. However, in a new study published in Science Advances, researchers have discovered one exception where genetic mutations don't appear to build up as humans get older—the mitochondrial DNA (mtDNA) of human egg cells in women.

For 25 years, scientists at Northwestern Medicine have been studying individuals aged 80 and older—dubbed "SuperAgers"—to better understand what makes them tick.

In a pair of new studies, researchers found that older adults who challenge themselves to learn new things are less likely to experience loneliness or depression, even during times of major upheaval.

Parenting over the summer holidays, especially when juggling work and childcare, comes with significant challenges. One of those is screen time and staying safe online.
