T cells use force to destroy cancer cells

As a part of our immune defenses, cytotoxic T cells—or killer T cells—seek out and destroy cells that are infected or cancerous. This process is essential for the body's defense against diseases.

Prospects for an all-optical remote magnetic field sensor

Crystals doped with rare-earth (RE) ions exhibit very narrow linewidths of optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range. RE-doped materials are widely ...

A key step toward growing human kidneys in the laboratory

Kidney disease affects one in nine adults globally and the incidence of kidney failure is steadily rising around the world. Being able to grow working kidney tissue in a laboratory could help accelerate medical treatments ...

Scientists develop new technique to reveal the hidden genome

Using an innovative new technique, scientists at Duke-NUS Medical School and their collaborators have identified thousands of previously unknown DNA sequences in the human genome that code for microproteins and peptides potentially ...

Signaling 'stressed-out' plants

A plant scientist from the University of Missouri has discovered a new way of measuring stress in plants, which comes at a time when plants are experiencing multiple stressors from heat, drought and flooding because of extreme ...

Investigators explore cellular response to stress

Northwestern Medicine investigators have discovered novel mechanisms that regulate a cell's response to molecular stressors, according to a study published in the Proceedings of the National Academy of Sciences.

Did gonorrhea give us grandparents?

Researchers at University of California San Diego School of Medicine previously found a set of human gene mutations that protect older adults against cognitive decline and dementia. In a new study, published July 9, 2022 ...

A new and easy-to-use web server to identify genome edited cells

A team of scientists from the IUF—Leibniz Research Institute for Environmental Medicine in Düsseldorf developed and validated a computational webserver that allows scientists to genotype mutations using nanopore sequencing. ...
