Medical Xpress / Bone-targeted estrogen delivery reverses postmenopausal osteoporosis without uterine side effects in mice
Postmenopausal osteoporosis is a condition that weakens bones, making them brittle and prone to fracture. Taking the hormone estradiol can reverse these effects, but it may also increase endometrial and uterine cancer risks. ...
Phys.org / Wine grape still carries molecular memory of its ancestry after 400 years, study finds
About 400 years ago, a cross between cabernet franc and sauvignon blanc gave birth to cabernet sauvignon. Today, cabernet sauvignon is the world's most-planted wine grape, dominating vineyards from Napa to Bordeaux. New research ...
Medical Xpress / Rare genetic variants can increase ADHD risk by up to 15 times
ADHD is a neurodevelopmental disorder with a high heritability, in which the genetic component consists of thousands of genetic variants. Most variants only slightly increase the likelihood of receiving the diagnosis. Now ...
Phys.org / How bacteria 'feel' surfaces: Fluorescent probe visualizes and quantifies membrane tension
In natural environments, bacteria rarely live as free-swimming cells but are attached to surfaces as biofilms in medical devices, mobile phones or human tissue. The bacterial behavior, how they attach and grow, group together ...
Medical Xpress / Targeted protein degradation: A new way to combat harmful proteins in tumor cells
A new active substance attacks a key protein in tumor cells, leading to complete degradation. In cell experiments, this caused cancer cells to lose their protection and die. The active substance was developed by researchers ...
Phys.org / Scientists directly observe diffusion behavior within individual nanostructures
In recent years, organic semiconductor materials have attracted considerable attention as key components for next-generation photoenergy conversion devices and organic solar cells due to their light weight and mechanical ...
Medical Xpress / NIH grant terminations leave thousands without access to care, study finds
Thousands of clinical trial participants lost access to important medical studies this year after the Trump administration terminated hundreds of National Institutes of Health (NIH) grants, according to new research published ...
Medical Xpress / Blink to the beat: Scientists discover that when we listen to music, we unconsciously blink our eyes
Yi Du and colleagues from the Chinese Academy of Sciences published an article in the open access journal PLOS Biology detailing their findings about a new way our bodies naturally respond to music. Given a steady beat, our ...
Phys.org / Bacteriophages: The hidden facilitators in kimchi fermentation
The World Institute of Kimchi has confirmed in a new study that bacteriophages, which were previously considered a "nuisance" during the process of food fermentation, actually play the role of key helpers that facilitate ...
Phys.org / Researchers decode the chemistry behind a deadly genetic disorder
Northeastern University researchers used an original machine learning tool to predict how genetic mutations cause a rare metabolic disease known as OTC deficiency, uncovering some underlying biochemical mechanisms at play ...
Medical Xpress / Even low-intensity smoking increases risk of heart attack and death, study finds
An analysis of data from almost two dozen long-term studies finds that even low-intensity smokers have a substantially higher risk of heart disease and death compared to people who never smoked, even years after they quit. ...
Tech Xplore / Wearable tech lets users control machines and robots while on the move
Engineers at the University of California San Diego have developed a next-generation wearable system that enables people to control machines using everyday gestures—even while running, riding in a car or floating on turbulent ...
