Japanese Researchers Trace Alzheimer’s Disease to Mutation in Common Enzyme

According to the World Health Organization, Alzheimer’s disease is the most common cause of senile dementia that affects dozens of millions of people worldwide, with numbers expected to double every 20 years if more effective treatments are not forthcoming. It has long been thought that Alzheimer’s disease is caused by […]

A New Tool for the Genomic Era

As early as 1975, biologists discovered that the protein-coding parts of the chimpanzee and human genomes are more than 99 percent identical. Yet, chimpanzees and humans are clearly different in significant ways. Why? The answer lies in the fact that how DNA is used is as important as what it […]

How cells use mechanical tension sensors to interact with their environment

Actin is among the most abundant proteins in cells, and it has many jobs—from giving the cell its very shape and structure to managing networks of proteins crucial to numerous cellular functions. Without it, the fragile fundamental unit of life would crumble. A good deal of actin’s activity is based […]

Researchers show why heat stress damages sperm

University of Oregon biologists have used a model organism to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat. In humans, the optimal temperature for sperm production is just below body temperature, in a range of about 90-95 degrees F. Human […]

Researchers discover mechanism linking gum disease to heart disease, other conditions

Researchers at the University of Toronto have found evidence that neutrophil immune cell activity is the missing link connecting periodontal disease with heart disease, cancer and other inflammatory conditions – possibly including COVID-19. The link between periodontal (gum) disease and other inflammatory conditions such as heart disease and diabetes has long been established, […]

Humans are born with brains ‘prewired’ to see words

Humans are born with a part of the brain that is prewired to be receptive to seeing words and letters, setting the stage at birth for people to learn how to read, a new study suggests. Analyzing brain scans of newborns, researchers found that this part of the brain – […]

Newly discovered mechanism controls cancer cell growth and metabolism

In a new study published in the journal Cell, Death & Differentiation researchers at Karolinska Institutet have conducted a translational study that identified a new mechanism for controlling the breakdown of glucose in several different cancer forms. The discovery could lead to new therapeutic strategies aimed to reduce cancer growth. […]

34% of older adults in the U.S. are prescribed potentially inappropriate drugs, raising health care costs by hundreds

The prescription of potentially inappropriate medications to older adults is linked to increased hospitalizations, and it costs patients, on average, more than $450 per year, according to a new University at Buffalo study. The research, which sought to determine the impact of potentially inappropriate medications on health care utilization and […]

At our cores, we’re all strengthened by ‘dumbbells’

How life works may come down to dumbbell-like bits of DNA. Rice University scientists on a long quest to study the structure and function of chromosomes have found that amid the apparent chaotic state of DNA during interphase, when cells are between divisions, there are pockets of order in the configuration […]

Antigravity treadmills help multiple sclerosis patients

For people with multiple sclerosis, a disease of the central nervous system, exercise is a proven way to hold off symptoms of fatigue and loss of mobility. But those same symptoms of the disease can cause such mobility issues in some people with MS that even getting started with exercising is […]

Nudges Combined with Machine Learning Triples Advanced Care Conversations Among Patients with Cancer

An electronic nudge to clinicians—triggered by an algorithm that used machine learning methods to flag patients with cancer who would most benefit from a conversation around end-of-life goals—tripled the rate of those discussions, according to a new prospective, randomized study of nearly 15,000 patients from Penn Medicine and published in […]

Delivering proteins to testes could someday treat male infertility

According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers reporting in ACS Nano have found a way to deliver a protein important for sperm cell production directly to […]

Tumor DNA in Spinal Fluid Could Help Doctors Better Monitor Childhood Brain Cancer

For many cancers, doctors are increasingly looking to the DNA that solid tumours shed into the bloodstream to help with diagnosis and monitoring. But brain cancer has been a different story thanks to the natural blockade created by the blood-brain barrier. Researchers at the University of Michigan Rogel Cancer Center and Michigan Medicine […]
