Fats and oils are essential to life. They provide energy, support the absorption of fat-soluble vitamins, contribute to the structure of cell membranes, and give foods their flavor, texture and mouthfeel. Yet the way fats are produced, processed and consumed is changing. Food man

A new collaborative study by Tel Aviv University and Sheba Medical Center marks a significant advance toward noninvasive blood testing, one of the most significant unmet needs in the market. The researchers have developed an artificial intelligence–based system capable of assessi

A second prostate-specific membrane antigen (PSMA) PET scan changed treatment plans for nearly half of patients whose first scan was negative, according to new research published in the July issue of The Journal of Nuclear Medicine. Findings from the repeat PSMA scans, which incl

Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Almost everyone carries Candida albicans. The yeast colonizes human mucous membranes—for example, the oral mucosa and the intestine—usually silently, without causing any problems. The immune system learns early on how to deal with it. It develops specialized immune cells known as

Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective methods to measure this exchange of ions, which is kn

How the proteins in our bodies bind together to form protein complexes plays a critical role in numerous cell functions—staving off diseases, for instance, or transporting ions across cell membranes. A better understanding of how they bind could lead to new medicines and possibly

Two diamonds formed 700 kilometers below the Earth's surface reveal a life-giving synchronicity between shifting continents and the cycling of phosphorus, a vital building block of DNA and cell membranes.

Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly adapt to changes in their environment.

Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins into their cell membranes. They explain that—contrar

Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb), is the world's deadliest single-agent infection, responsible for 1.23 million deaths in 2024, according to the World Health Organization. The bacterium's unique outer cell membrane is notoriously hard to pene

We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keep
