New method sees fibers in 3D, uses it to estimate conductivity

Designing a vehicle that can drive away the heat that is generated around it when traveling at hypersonic speeds requires an understanding of the thermal properties of the materials used to construct it. A recent study developed a method to create 3D models of the fibers within composite materials then used that information to predict the thermal conductivity of the material.

US official says every American who wants a covid-19 vaccine will have one by June

An official with the US covid-19 vaccine initiative says anyone in the country who wants a vaccine will be able to have it by June, seven months from now. The confident projection was made by retired Lieutenant General Paul Ostrowski, director of supply, production, and distribution for Operation Warp Speed, during an appearance on MSNBC on Monday, November 30. “A hundred percent of...

New method sees fibers in 3-D, uses it to estimate conductivity

As a vehicle travels through space at hypersonic speeds, the gases surrounding it generate heat at dangerous temperatures for the pilot and instrumentation inside. Designing a vehicle that can drive the heat away requires an understanding of the thermal properties of the materials used to construct it. A recent two-part study at the University of Illinois Urbana-Champaign developed a method to...

Molecule that regulates muscle adaptation to exercise is discovered

The onset of any physical exercise program causes muscle pain that can hinder movements as simple as getting up from a sofa. With time and a little persistence, the muscles become accustomed to the effort, developing more strength and endurance. Researchers affiliated with Harvard University in the United States and the University of São Paulo (USP) in Brazil describe the cellular mediator that...

Stimulus relief funds increase social distancing to stop spread of COVID-19

As case rates of COVID-19 reach new heights across the nation, many states and cities are tightening stay-at-home restrictions to stop the spread. New research suggests that that those suffering from economic hardships are less likely comply with new stay-at-home orders; however, these same U.S. residents would be more likely to adhere to the new public health guidelines if their households...

Seismic activity of New Zealand's alpine fault more complex than suspected

A rupture along the full length of the fast-slipping Alpine Fault on New Zealand's South Island poses the largest potential seismic threat to the southern and central parts of the country. But new evidence of a 19th century earthquake indicates that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events.

Mapping stellar nurseries in the Milky Way

An international team of Astronomers from the Cosmostatistics Initiative (COIN) identified nearly 120,000 new young stellar objects (YSOs) based on data from the Infrared Array Camera of NASA's Spitzer Space Telescope. The final catalog, named SPICY (Spitzer/IRAC Candidate YSO Catalog), is publicly available to anyone who wishes to study the first stages of stellar development.
