by Brian H. Waters, Johns Hopkins University School of Medicine There’s no question that as body weight increases, so too does blood pressure. Now, in a study of mice, Johns Hopkins researchers have revealed exactly which molecules are likely responsible for the link between obesity and blood pressure. Blocking one of these molecules—a signaling channel...

Lack of sleep affects fat metabolism
by American Society for Biochemistry and Molecular Biology We’re all a little short on sleep during the work week. A new study adds to the mounting evidence about just how harmful lack of sleep can be. In the Journal of Lipid Research, researchers at Pennsylvania State University report that just a few days of sleep...

How pregnancy changes women’s metabolism and immune systems
by April Rees, Ben Jenkins and Catherine Thornton, The Conversation Some of the changes that happen to a woman’s body during pregnancy are more obvious than others. We all know that women usually get a visible bump, they might have morning sickness initially, and swollen ankles later on, but pregnancy can also change some of...

Deleting Old Cells
Posted Today This news or article is intended for readers with certain scientific or professional knowledge in the field. New research from Harvard Medical School researchers at Joslin Diabetes Center has shown that insulin resistance in mice increases the proportion of dysfunctional aged beta cells. Such an increase in aged beta cells could lead to type 2 diabetes. The...

Antibiotic produced by the microbiome kills bacteria by disturbing energy metabolism
GERMAN CENTER FOR INFECTION RESEARCH A research team from the Universities of Tübingen and Göttingen as well as from the German Center for Infection Research has investigated the mode of action of a new class of antibiotics that is highly effective against multidrug-resistant pathogens. The so-called fibupeptides impair the energy supply to the bacterial cell, consequently causing...

Easy ways to rev up your metabolism and burn calories
After age 25, metabolism naturally slows by 5 percent every decade. So if you eat as much in your 40s as you did in your 20s, you’re going to add extra pounds—especially if you exercise less and lose muscle. In addition to weight training to maintain muscle, these tips from the American Council on Exercise...

How does exercise prompt fat to benefit metabolism?
An international team of scientists has uncovered molecular evidence of how exercise benefits metabolism and health through its effect on fat. The evidence reveals that fat plays an active role in the process. The finding follows earlier work in which the researchers were the first to show that exercise prompts fat tissue to release molecules that...

Study overturns dogma of cancer metabolism theory
Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism. Image shows squamous cell skin cancer tumors with lactate production (a byproduct of glucose...

Clinical trial launches to develop breath test for multiple cancers
Researchers have launched a clinical trial to develop a breath test, analysing molecules that could indicate the presence of cancer at an early stage. This is the first test of its kind to investigate multiple cancer types. A cancer breath test has huge potential to provide a non-invasive look into what’s happening in the body and could help to find cancer early when treatment is more likely to be...
