If you’ve ever had a bad case of jet lag, you know how a disruption to your body’s circadian rhythm makes it difficult to function. Molecular circadian “clocks” exist in cells throughout the body, governing more than just sleep and wake cycles – they are crucial to many aspects of human health. For more than…
BOSTON – A long-running debate over how an important gene-silencing protein identifies its targets has been resolved by researchers at Massachusetts General Hospital (MGH). Their findings, reported in Nature Structural and Molecular Biology, also explain certain mysteries about the behavior of this protein, known as Polycomb repressive complex 2 (PRC2). PRC2 helps regulate whether genes…
LOS ANGELES — A growing number of women forgoing reconstruction after a mastectomy say they’re satisfied with their choice, even as some did not feel supported by their physician, according to a study led by researchers at the UCLA Jonsson Comprehensive Cancer Center.

The second is that conventional medications take a relatively long time – around three to five weeks – to have the desired effect. A group of…
One of the most promising areas of human cancer research is the study of signal transduction, or cell signaling. Communication between and within cells in the body is accomplished through signal transduction, as stimuli generated in one part of an organism travels through the circulatory system and initiates a response in specific target cells. As…
The Microbial Engineering community has made extraordinary progress toward developing a number of promising vaccine candidates to provide proection against COVID-19. This January 26 webinar, sponsored by Engineering Conferences International (ECI), will focus on a variety of programs based either on microbial platforms or cell gree synthesis. ECI a not for profit global engineering conferences…
As governments around the world rush to vaccinate their citizens against the surging coronavirus, scientists are locked in a heated debate over a surprising question: Is it wisest to hold back the second doses everyone will need, or to give as many people as possible an inoculation now — and push back the second doses…
