Researchers within the Biomedicine Discovery Institute at Monash University have made a breakthrough in understanding the role played by high-risk immune genes associated with the development of rheumatoid arthritis (RA).
The findings, published in Science Immunology, were the result of a seven-year collaboration led by Monash University, involving Janssen Research and Development, USA and the Karolinska Institute, Sweden.
The social science literature has long viewed homophily and network-based job recruitment as crucial drivers of segregation. Researchers at Linköping University and ESADE, Ramon Llull University now show that this view must be revised. In their Science Advances article, they call attention to a previously unidentified factor, the Trojan-horse mechanism, which shows that network-based recruitment can reduce rather than increase segregation levels.
Although antibodies induced by SARS-CoV-2 infection are largely protective, they do not completely protect against reinfection in young people, as evidenced through a longitudinal, prospective study of more than 3,000 young, healthy members of the US Marines Corps conducted by researchers at the Icahn School of Medicine at Mount Sinai and the Naval Medical Research Center, published April 15 in The Lancet Respiratory Medicine.
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses.
Boulder, Colo., USA: Volcanologists' ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth's crust. But what happens if the magma can't be spotted?
Shane Rooyakkers, a postdoctoral scholar at GNS Science in New Zealand, grew up in the shadow of Mount Taranaki on the country's North Island, hiking on the island's many volcanoes. Today, his research is revealing hidden dangers that may have been beneath his feet all along.
LA JOLLA, CALIF. - April 16, 2021 - Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers' understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body's frontline virus fighters.
The study was published in the journal Molecular Cell.
Faced with the tragic loss of the Arecibo observatory in Puerto Rico and the often prohibitive cost of satellite missions, astronomers are searching for savvy alternatives to continue answering fundamental questions in physics.
At a press conference during the 2021 APS April Meeting, they will reveal new tactics across both hemispheres for illuminating gravitational waves and dark matter.
Shining the oldest light in the universe on dark matter
JUPITER, FL--Making memories involves more than seeing friends or taking photos. The brain constantly adapts to new information and stores memories by building connections among neurons, called synapses. How neurons do this--reaching out arm-like dendrites to communicate with other neurons--requires a ballet of genes, signaling molecules, cellular scaffolding and protein-building machinery.
AMES, Iowa - A lot is riding on the continued advancement of plant sciences.
Take the food supply, for starters. Climate change and population growth will continue to pose challenges in the future, and crop production will require innovation and progress by plant scientists in order to keep pace. It isn't an overstatement to say that populations around the world will go hungry if plant science stagnates, said Gustavo MacIntosh, a professor in the Roy J. Carver Department of Biochemistry, Biophysics and Molecular Biology at Iowa State University.
When the Electron Ion Collider received the go-ahead in January 2020, it became the only new major accelerator in the works anywhere in the world.
"All the stars aligned," said Elke-Caroline Aschenauer, Brookhaven National Laboratory Staff Scientist and a leader in developing the EIC plans. "We have the technology to build this unique particle accelerator and detector to do the measurements that, together with the underlying theory, can for the first time provide answers to longstanding fundamental questions in nuclear physics."
