Study identifies key mechanism regulating how cells use fat to generate energy
Study identifies key mechanism regulating how cells use fat to generate energy
An international study by scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) and the University of California, Los Angeles (UCLA) has identified a fundamental mechanism that regulates how the body uses stored fat to produce energy.

This frog bacterium wiped out cancer tumors in mice with a single dose
This frog bacterium wiped out cancer tumors in mice with a single dose
A naturally occurring bacterium from amphibian intestines completely eliminated colorectal tumors in mice with a single treatment by both attacking cancer cells and activating the immune system. The findings point to a promising new type of cancer therapy that could one day work

Ribosome-based gene circuit lets cells read six signals and trigger responses
Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene circuit' platform that can simultaneously read multiple

Immune cells get transformed into fungus-fighting nanoparticles
Immune cells get transformed into fungus-fighting nanoparticles
Tiny particles made from the membranes of human immune cells could offer a promising new way to fight fungal infections that are becoming harder to treat. Engineers at the University of California San Diego created antifungal nanoparticles that target Candida albicans, a fungus r

This ultrasound treatment may help stop arthritis before it starts
This ultrasound treatment may help stop arthritis before it starts
A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells c

Alzheimer's tau protein has a surprising secret role in memory
Alzheimer's tau protein has a surprising secret role in memory
Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the re

RNA-only repair enzyme reveals how primordial life could have protected genomes
RNA-only repair enzyme reveals how primordial life could have protected genomes
In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.

New cell imaging method shines a light on blind spots
New cell imaging method shines a light on blind spots
Cells are crowded, dynamic places where thousands of molecules interact in tight quarters. Until now, scientists lacked a reliable way to see many of these molecular interactions as they happen. Researchers at the University of Illinois Chicago have now developed a new imaging me

Scientists discover why peach fuzz can suddenly make you itch
Scientists discover why peach fuzz can suddenly make you itch
A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the research could pave the way for m
