How old are you for your age? Scientists who study ageing have begun to distinguish chronological age: how long it's been since a person was born, and so-called biological age: how much a body is “aged” and how close it is to the end of life. These researchers are uncovering […]

Greater maternal stress during pregnancy is linked with significant increases in the number and variety of infant illness during the first year of life, independent of the level of stress after birth, according to a study led by researchers at UC San Francisco. The study, published in the Journal of […]

Genomes are routinely subjected to DNA damage. But most cells have DNA repair systems that enforce genome stability and, ideally, prevent diseases like cancer. The trouble gets serious when these systems break down. When that happens, damage such as unrepaired DNA lesions can lead to tumors, and genomic chaos ensues. […]

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it’s next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to […]

A team of scientists led by a researcher at the Case Western Reserve University School of Medicine is making strides to fight deadly metastatic breast cancer by combining nanotechnology with immunotherapy. Efstathios “Stathis” Karathanasis, an associate professor of biomedical engineering, is directing the novel technique—sending nanoparticles into the body to […]

Species typically evolve over the course of eons, but researchers at the University of Minnesota have developed a way to do it in less than a year.

A team of researchers at CHU Sainte-Justine and Université de Montréal has succeeded in using bioinformatics to develop a statistical model to assess how the gain or loss of genetic material impacts the risk of autism. The results of this work are presented in the American Journal of Psychiatry. This […]

The immune system usually mounts a strong immune response to infection by SARS-CoV-2, the virus that causes COVID-19. That defensive response, however, appears to be weaker in men and people over the age of 60, a study led by researchers at the University of Washington School of Medicine in Seattle has […]

UT Health physicians use supercomputers to interpret results of traumatic brain injury clinical trial. Individuals with traumatic brain injuries, or TBIs, frequently experience the shrinking or atrophying of brain tissue near where the injury occurred, causing additional damage beyond the original harm. If this can be prevented, many could function […]

Researchers are able to visualize the retina's function at the cellular level, which will help accelerate cures for blinding diseases. While there is no cure for blindness and macular degeneration, scientists have accelerated the process to find a cure by visualizing the inner workings of the eye and its diseases at […]

A cure for type-1 diabetes has come closer with the development of a new method for keeping transplanted insulin-producing cells alive and functional in recipients for long periods even when transplanted underneath the skin. A team led by researchers at the Perelman School of Medicine at the University of Pennsylvania […]

A new study from McGill University’s Goodman Cancer Research Centre (GCRC) has revealed significant biological changes in mice expressing an activated, mutant form of the Estrogen Receptor alpha (ER alpha), shedding new light on the role of this important gene in development and cancer. Over-expressed in approximately 70 % of breast cancer cases, the Estrogen Receptor is often associated […]

For artificial intelligence (AI) tools being developed at Case Western Reserve University to have impact in the fight against cancer, they’re going to have to be validated in rigorous human clinical trials. That validation may be a step closer following two recent agreements among bioengineering pioneer Anant Madabhushi, a longtime […]
