Drug mimics beneficial effects of fasting in mice: Blocking arginine metabolism leads to improved metabolic health, weight loss
An investigational cancer drug that starves tumors of their energy supply also shows evidence of improving whole body metabolism, leading to improved weight control, according to a new study in mice from researchers at Washington University School of Medicine in St. Louis. The findings are published in the journal Cell Reports Medicine. In a group […]
Life arose on hydrogen energy, researchers suggest
How did the first chemical reactions get started at the origin of life and what was their source of energy? Researchers at the Heinrich Heine University Düsseldorf (HHU) have reconstructed the metabolism of the last universal common ancestor, LUCA. They found that almost all chemical steps used by primordial life to piece together the molecular […]
New link between diet, intestinal stem cells and disease discovered
The intestine is essential for maintaining our energy balance and is a master at reacting quickly to changes in nutrition and nutrient balance. It manages to do this with the help of intestinal cells that among other things are specialized in the absorption of food components or the secretion of hormones. In adult humans, the […]
Energy efficiency instead of long-term storage
Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation’s buildings entirely with renewable energy, according to analysis conducted by researchers at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL). As more communities plan to eventually rely on 100% renewable energy, the researchers offer a strategy that […]
Potential indicator for obesity risk detected during sleep
Throughout the day, we gain energy by breaking down carbohydrates, fats, and proteins in our bodies through the process of metabolism. For example, immediately after eating, most of our energy comes from carbohydrates, while after fasting, most comes from fats. The body’s ability to switch metabolic energy sources in response to changes in nutritional state, […]
Janus graphene opens doors to sustainable sodium-ion batteries
In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world’s most common and cheap metal ions — sodium. The results show that the capacity […]
Scientists detect characteristics of the birth of a major challenge to harvesting fusion energy on Earth
A key challenge for scientists striving to produce on Earth the fusion energy that powers the sun and stars is preventing what are called runaway electrons, particles unleashed in disrupted fusion experiments that can bore holes in tokamaks, the doughnut-shaped machines that house the experiments. Scientists led by researchers at the U.S. Department of Energy’s […]
Collisions of light produce matter/antimatter from pure energy
Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) — a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory — have produced definitive evidence for two physics phenomena predicted more than 80 years ago. The results were derived from a detailed analysis of […]
