Retinal cells derived from a cadaver human eye survived when transplanted into the eyes of primate models, an important advance in the development of cell therapy to treat blindness, according to a study published on January 14 in Stem Cell Reports. The retinal pigment epithelium (RPE), a layer of pigmented cells in the retina, functions […]
As dozens of countries blocked the flow of people and goods from Britain to avoid a new and more contagious strain of coronavirus, scientists raced to understand how it emerged and the scope of its threat. Here are some of the key questions they are asking, and the answers that have emerged so far. How […]
Mutations in proteins called histone H1, which help package DNA in chromosomes, are a frequent cause of lymphomas, according to a study led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and The Rockefeller University. The findings could lead to new approaches to treating these cancers. Scientists in recent years have observed that mutations in histone […]
THURSDAY, Dec. 10, 2020 — The first known case of COVID-19 triggering a recurrence of Guillain-Barré syndrome has been reported by researchers. Guillain-Barré syndrome — which can be sparked by viral and bacterial infections — is a rare disorder where the body’s immune system attacks nerves. It can result in respiratory failure and death. There […]
The COVID-19 pandemic continues to cause significant illness and death while treatment options remain limited. St. Jude Children’s Research Hospital scientists have discovered a potential strategy to prevent life-threatening inflammation, lung damage and organ failure in patients with COVID-19. The research appeared online in the journal Cell. The scientists identified the drugs after discovering that […]
Researchers at the Hong Kong University of Science and Technology (HKUST) have identified new therapeutic targets for Alzheimer’s disease (AD) by studying the patients’ brain with a newly-developed methodology. This novel approach also enables researchers to measure the effects of potential drugs on AD patients, opening new directions for AD research and drug development. Although […]
Imagine you’ve just arrived in Paris. Your body thinks it should be midnight—a restorative time when your cells typically proofread DNA, organize and store energy, and perform other essential chores—but, instead, the sun is up and you’re awake. On a molecular level, your cells are stressed, trying to catch up to new environmental conditions. Shiftwork […]
As scientists around the world develop life-saving COVID-19 vaccines and therapies, many are still wondering exactly why the disease proves deadly in some people and mild in others. To solve this puzzle, scientists need an in-depth understanding of how the body’s many types of immune cells respond to SARS-CoV-2, the virus that causes COVID-19. A […]
MONDAY, Oct. 5, 2020 — Two U.S. researchers and a British scientist have been awarded the 2020 Nobel Prize in physiology or medicine for major contributions to the fight against blood-borne hepatitis. Hepatitis C causes 400,000 deaths worldwide each year, The Washington Post reported. The three recipients are: Harvey Alter, a clinical scientist at a […]
Through the development of new technology, University of Minnesota researchers have developed a method that allows scientists to understand how a fruit fly’s brain responds to seeing color. Prior to this, being able to determine how a brain responds to color was limited to humans and animals with slower visual systems. A fruit fly, when […]
