Research has shown that a mutation in the ATAXIN-1 gene leads to accumulation of Ataxin-1 (ATXN1) protein in brain cells and is the root cause of a rare genetic neurodegenerative disease known as spinocerebellar ataxia type 1 (SCA1). How healthy cells maintain a precise level of ATXN1 has remained a mystery, but now a study…
In 1952, Alan Turing published a study which described mathematically how systems composed of many living organisms can form rich and diverse arrays of orderly patterns. He proposed that this ‘self-organisation’ arises from instabilities in un-patterned systems, which can form as different species jostle for space and resources. So far, however, researchers have struggled to…
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions. So far, however, researchers’ understanding of…
Gregory Foster, Professor, Chemistry and Biochemistry, Thomas Huff, Assistant Director, Shared Research Instrumentation Facility Specialization, Potomac Environmental Research and Education Center (PEREC), Randolph McBride, Associate Professor, Geology and Oceanography, PEREC, and Scott Glaberman, Assistant Professor, Environmental Science and Policy, are conducting a study with a goal of collecting water and sediments in the Hunting Creek…
Baltimore, MD– New work led by Carnegie’s Meredith Wilson and Steve Farber identifies a potential therapeutic target for clogged arteries and other health risks that stem from an excess of harmful fats in the bloodstream. Their findings are published by PLOS Genetics. “Cardiovascular disease occurs when lipids from the blood plasma are deposited in the…
New Haven, Conn. — Researchers at the Yale Liver Center found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies. They also discovered that higher levels of liver enzymes — proteins released when the liver is damaged — were associated with poorer outcomes for these patients,…
Using inexpensive and widely available tools, scientists have developed a simple approach to visually evaluate how effectively different types of masks prevent the spread of droplets that could contain SARS-CoV-2 virus particles, according to a new study. While the authors note their work is still in the early stages, and their method has so far…
By applying the renewal theory in probability to reduce recall bias in initial case reports, scientists have come up with a new estimate for the incubation period of COVID-19. Their mean estimate of 7.76 days, longer than previous estimates of 4 to 5 days, involves the largest amount of patient samples to date in such…
Discovering antiviral and anticancer drugs will soon be faster and cheaper thanks to new research from Simon Fraser University chemist Robert Britton and his international team. For the past 50 years, scientists have used manmade, synthetic and nucleoside analogues to create drug therapies for diseases that involve the cellular division and/or the viral reproduction of…
In June, the photographer Shakira Rochelle started taking photographs of Black Lives Matter protesters in her hometown Cincinnati. She shared the images and other supportive B.L.M. content on her personal Instagram account. Shortly, thereafter she received a text from a couple who had hired her to photograph their wedding. In a screenshot of the text…
