The evidence to date strongly suggests that environmental factors determine longevity for the vast majority of people. If there are significant longevity-affecting gene variants out there, then they have small and unreliable effects (APOE), or are restricted to tiny lineages (SERPINE1), or both. The overwhelming majority of contributions to longevity […]

T cells of the adaptive immune system collectively become less functional with age. The immune system as a whole becomes more inflammatory and less effectively, a state described by the terms inflammaging and immunosenescence. Researchers here note that T cells struggle to survive in the aged environment, and are as […]

In today's open access research, the authors report on the generation of a biomarker of aging from the study of proteins secreted by senescent cells. Low cost assays that map closely to biological age, the burden of damage, are a potentially useful tool for research and development of rejuvenation therapies. […]

Chimeric antigen receptor (CAR) T cell therapies target specific surface features on other cells by providing T cells with a way to recognize that feature – the CAR. T cells so equipped will selectively destroy other cells with the target surface feature. To produce a CAR T cell therapy, a […]

In a new study, a computer algorithm improved the accuracy and efficiency of cervical cancer screening compared with cytology (Pap test), the current standard for follow-up of women who test positive with primary human papillomavirus (HPV) screening.

National Institutes of Health investigators and colleagues have discovered that when the immune system first responds to infectious agents such as viruses or bacteria, a natural brake on the response prevents overactivation. Their new study in mBio describes this brake and the way pathogens such as SARS-CoV-2, the virus that causes […]

Princeton researchers have created a device that can herd groups of cells like sheep, precisely directing the cells’ movements by manipulating electric fields to mimic those found in the body during healing. The technique opens new possibilities for tissue engineering, including approaches to promote wound healing, repair blood vessels, or […]

The role genetics and gut bacteria play in human health has long been a fruitful source of scientific enquiry, but new research marks a significant step forward in unraveling this complex relationship. Its findings could transform our understanding and treatment of all manner of common diseases, including obesity, irritable bowel […]

In a study in mice, researchers at Karolinska Institutet have discovered a new potential therapeutic approach to facilitate neurological recovery in people with diabetes suffering from a stroke. The treatment strategy is based on the chronic normalization of hyperglycemia after stroke. The scientists hope that these new results, presented in […]

As COVID-19 restrictions loosen this summer, Canadians will spend more time outdoors and make the most of the sunshine. A new study from McGill University suggests why men may be more genetically prone to develop skin cancer. The research led by Professor Ian Watson of McGill’s Goodman Cancer Research Centre […]

An international research team led by Dr. Tali Ilovitsh of the Biomedical Engineering Department at TAU developed a noninvasive technology platform for gene delivery into breast cancer cells. The technique combines ultrasound with tumor-targeted microbubbles. Once the ultrasound is activated, the microbubbles explode like smart and targeted warheads, creating holes in cancer cells' […]

The expansion of the human brain during evolution, specifically of the neocortex, is linked to our cognitive abilities such as reasoning and language. Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden have been studying a gene called ARHGAP11B for many years. This gene […]

A new method of analysing cancer patients’ blood for evidence of the disease could be up to ten times more sensitive than previous methods according to new research led by the University of Cambridge. In the coming years, this method and others based on this approach could lead to tests […]

Chemical engineers from the USC Viterbi School of Engineering have unlocked a fatal vulnerability in many cancer cells—sugar inflexibility. Like any cells in the body, cancer cells need sugar ­– namely glucose – to fuel cell proliferation and growth. Cancer cells in particular metabolize glucose at a much higher rate […]

New images of an enzyme in action as it interacts with the chromosome could provide important insight into how cells — including cancer cells — regulate their genes. The enzyme, LSD1, can “turn off” gene expression by removing chemical flags (methyl groups) from the nucleosome — tightly packed units of […]

One woman shares her experience with the Ross procedure, an aortic valve replacement surgery performed by only a few cardiac surgeons in the country.
