Phys.org / The (metabolic) 'cost of life': New method quantifies hidden energy costs of maintaining metabolic pathways
There are "costs of life" that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active—such as those that make up photosynthesis, although the examples are ...
Medical Xpress / Plastic particles can increase intestinal inflammation
A research team led by the Medical University of Vienna and the University of Vienna has investigated a possible link between the rising number of people with chronic inflammatory bowel disease and the increasing exposure ...
Medical Xpress / Stopping weight-loss jabs leads to much faster rebound than thought—so are they still worth it?
Weight-loss injections, like Wegovy and Mounjaro, have been hailed as gamechangers. In clinical trials, people lost an average of 15%–20% of their body weight—results that seemed almost miraculous compared to traditional ...
Phys.org / Single-atom photocatalyst enables green, oxidant-free C–H cross-coupling reactions
Chemists from the National University of Singapore (NUS) have developed a single-atom photocatalytic strategy that enables oxidant-free cross-dehydrogenative coupling (CDC) reactions between ring-shaped aromatic molecules ...
Medical Xpress / New US diet guidelines push whole foods, meat and dairy
The federal government has released new dietary guidelines that shift how Americans are urged to eat.
Medical Xpress / Rental aid during pandemic boosted mental health
Federal rental assistance distributed during the COVID-19 pandemic did far more than help people stay in their homes. It also improved their mental health.
Phys.org / 'Stomata in-Sight' system allows scientists to watch plants 'breathe' in real-time
For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide into the leaf for photosynthesis ...
Phys.org / Microbes may hold the key to brain evolution
A new study reveals that changes to the gut microbiome can change the way the brain works.
Phys.org / From pint to plate, scientists brew up a new way to grow meat
Yeast left over from brewing beer can be transformed into edible "scaffolds" for cultivated meat—sometimes known as lab-grown meat—which could offer a more sustainable, cost-effective alternative to current methods, according ...
Medical Xpress / Three in four new Australian moms struggle with body image, study finds
Up to 75% of Australian women report concerns about their body image after giving birth, with many feeling intense pressure to "bounce back" to their pre-pregnancy shape, a pressure that can even trigger eating disorders ...
Phys.org / Study overturns long-held model of how plants coordinate immune responses
Plants mobilize their immune defenses far earlier than scientists have believed for decades—and through a previously overlooked early signaling mechanism—according to a new study published in Nature Plants.
Medical Xpress / Vitamin C may help protect fertility from a harmful environmental chemical
A new discovery at the University of Missouri reveals that vitamin C may help protect reproductive health from a harmful environmental chemical. Using a fish model, researchers found that exposure to potassium perchlorate, ...
