New research reveals hidden processes at work in the hearts of large stars. Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these enormous stars has a major impact on our understanding of their evolution prior to their explosion. It also represents the largest uncertainty for scientists studying their structure and evolution.

In doing so, a researcher has found it could protect men from stomach inflammation. Autoimmune diseases have something in common with horses, bachelor’s degrees and daily flossing habits: women are more likely to have them.

One reason for autoimmune diseases’ prevalence in women may be sex-based differences in inflammation. In a new study, West Virginia University researcher Jonathan Busada investigated how sex hormones affect stomach inflammation in males and females. He found that androgens — or male sex hormones — may help to keep stomach inflammation in check.

“Stomach cancer is primarily caused by rampant inflammation,” said Busada, an assistant professor in the School of Medicine and researcher with the Cancer Institute...

Researchers at North Carolina State University have made what is believed to be the smallest state-of-the-art RFID chip which should drive down the cost of RFID tags. In addition, the chip’s design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies.

“As far as we can tell, it’s the world’s smallest Gen2-compatible RFID chip,” says Paul Franzon, corresponding author of a paper on the work and Cirrus Logic Distinguished Professor of Electrical and Computer Engineering at NC State.

Gen2 RFID chips are state of the art and are already in widespread use. One of the things that sets these new RFID chips apart is their size. They measure 125 by 245 micrometers.

Manufacturers were able to make s...

Conventional studies investigating the effects of reduced gravity on muscle mass and function have used a ground control group that is not directly comparable to the space experimental group. Researchers from the University of Tsukuba set out to explore the effects of gravity in mice subjected to the same housing conditions, including those experienced during launch and landing. “In humans, spaceflight causes muscle atrophy and can lead to serious medical problems after return to Earth” says senior author Professor Satoru Takahashi. “This study was designed based on the critical need to understand the molecular mechanisms through which muscle atrophy occurs in conditions of microgravity and artificial gravity.”

Two groups of mice (six per group) were h...
