The goal wasn’t to stock up for long hours in the lab, but rather to […]Continue Reading ...
Injecting senescent cells into young mice results in a loss of health and function but treating the mice with a combination of two existing drugs cleared the senescent cells from tissues and restored physical function. The drugs also extended both life span and health span in naturally aging mice, according to a new study in […]Continue Reading ...
Credit: University of Nottingham Researchers have uncovered a supplement that can control the production of brown ‘good’ fat in babies—a discovery that will help understand and tackle issues related to obesity and metabolism in later life. The study, published today in Scientific Reports, shows how when mothers consume a diet supplemented with canola oil during […]Continue Reading ...

A new study at The University of Toledo shows that a father donates not one, but two centrioles through the sperm during […]Continue Reading ...
An explanted zebrafish heart loops on its own in a petri dish (left), but without the Frizzled-7a factor necessary for Planar Cell Polarity signaling, it remains tubular (right). Credit: Anne M. Merks, MDC When it first starts to develop, the heart is a simple tube. Reporting in the journal Nature Communications, researchers at MDC have […]Continue Reading ...

Julie Gosse, a University of Maine associate professor of molecular and biomedical sciences, has scanned the supermarket aisles for products that contain triclosan (TCS), a synthetic antibacterial agent. Since the ’90s, TCS has been in a slew of consumer products, including […]Continue Reading ...
The voltage sensor has two cavities (purple) that do not connect. Mutations (red) linked to periodic paralysis allow them to join, thereby creating a pore through which ions can leak. Compounds (blue and yellow) that block the pore could treat the condition. Credit: Ning Zheng & Catterall labs/UWMedicine A rare genetic disorder in which people […]Continue Reading ...
A radiologist outfitted with the team’s head-mounted eye-tracking device examines a mammogram. Credit: Hong-Jun Yoon/Oak Ridge National Laboratory, U.S. Dept. of Energy In an effort to reduce errors in the analyses of diagnostic images by health professionals, a team of researchers from the Department of Energy’s Oak Ridge National Laboratory has improved understanding of the […]Continue Reading ...
The California mouse is used as a model for examining parental behaviors because they are monogamous and, much like humans, both male and female partners contribute to neonatal-rearing. Credit: University of Missouri-Columbia Past studies have shown that biparental care of offspring can be affected negatively when females and males are exposed to bisphenol A (BPA); […]Continue Reading ...
Estrogen supplements change the bacterial composition in the intestinal tract, affecting how estrogen is metabolized, according to a new study in mice by researchers at the U. of I. From left (front row): postdoctoral research associate Xiaoji (Christine) Liu; Colleen Bushell, National Center for Supercomputing Applications senior research scientist; food science and human nutrition professor […]Continue Reading ...
ut organoids are three-dimensional balls of intestinal tissues grown in the lab from stem cells that allow researchers to examine the role different types of cells play in bowel health. The red stain marks cell outlines, while DNA is shown in blue. Credit: University of Toronto The University of Toronto’s David McMillen and his research […]Continue Reading ...
For years, researchers have studied how the body’s microbiome impacts virtually every aspect of human health ranging from the immune system to mental wellness. But, a recent study led by a multi-institutional research team, including the University of Maryland, several institutions in South Korea, and Purdue University, sheds new light on how the food we […]Continue Reading ...
Credit: CC0 Public Domain Researchers at University of California San Diego School of Medicine have found a new way to block a root cause of pain. The key is a naturally occurring protein called apolipoprotein A-I binding protein (AIBP). AIBP binds to toll-like receptor 4 (TLR4), a protein that sits on the surface of cells […]Continue Reading ...
