Scientists discover what triggers belly fat as we age
Scientists discover what triggers belly fat as we age
Aging may trigger the appearance of specialized stem cells that supercharge the body's ability to create new belly fat. The discovery reveals a potential biological driver of middle-age weight gain and a promising target for future anti-obesity treatments.

Peptide alternative to antibiotics could combat antimicrobial resistance crisis
A University of Alberta research team has designed a promising alternative for treating antimicrobial-resistant infections, a pressing global health issue. In a paper recently published in Cell Biomaterials, the team describes preclinical testing results for its human-derived pep

This tiny organism contracts 200 times faster than we can blink—here's how
A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ambiguum, uses a calcium-activated protein network in a f

Understudied enzyme helps S. aureus pathogen prosper, study finds
A new study published in the Proceedings of the National Academy of Sciences has offered insight into how Staphylococcus aureus, a major human pathogen, fine-tunes its internal machinery to survive stress and potentially cause infection. The research uncovers new details about th

Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class

New cellular model for rare and deadly melanomas enables study of immunotherapy resistance
A research team at the University of Turku in Finland has developed a reliable laboratory model to study BAP1-deficient melanomas, which are a rare type of melanoma that evade the immune system once they have metastasized and are universally resistant to current state-of-the-art

Lipids and DNA nanostructures independently control artificial cell mechanics
What if the mechanical properties of a cell could be programmed like the components of a machine? Researchers at the University of Tokyo have discovered that two fundamental modes of cellular deformation—stretching and bending—can be independently controlled using different molec

Scientists may have finally found how Alzheimer's spreads through the brain
Scientists may have finally found how Alzheimer's spreads through the brain
A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow

Jellyfish reveal rapid repair system behind scar-free healing
Jellyfish reveal rapid repair system behind scar-free healing
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology at the University of Chicago, Malamy had received tran

Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.
