Ingesting more data than ever, exascale model will simulate the impact of climate change on humans

 

The European Union is finalizing plans for an ambitious “digital twin” of planet Earth that would simulate the atmosphere, ocean, ice, and land with unrivaled precision, providing forecasts of floods, droughts, and fires from days to years in advance.

Explore the history of computers + micro-electronics technology at the virtual museum called Chips etc. — 1,000 rare parts from the world’s foremost electronics + semi-conductor companies.

 

People from every generation have a fascination with the evolution of computers: whether it’s chips, computer hardware, or ephemera. Both specialists and amateurs — hobbyist, makers, historians, engineers, and scientists — enjoy vintage computer parts. Since computing first began in the 20th century, the field has been progressing in leaps + bounds — making these historic markers of the past even more interesting.

Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new finding indicates that some small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.

Researchers at Mass Eye and Ear have developed a unique diagnostic tool that can detect dystonia from MRI scans, the first technology of its kind to provide an objective diagnosis of the disorder. Dystonia is a potentially disabling neurological condition that causes involuntary muscle contractions, leading to abnormal movements and postures. It is often misdiagnosed and can take people up to 10 years to get a correct diagnosis.

 

In a new study published September 28 in PNAS, researchers developed an AI-based deep learning platform -called DystoniaNet – to compare brain MRIs of 612 people, including 392 patients with three different forms of isolated focal dystonia and 220 healthy individuals. The platform diagnosed dystonia with 98.8 percent accuracy. During the process, the researchers identified a new microstructural neural network biological marker of dystonia. With further testing and validation, they believe DystoniaNet can be easily integrated into clinical decision-making.

Like many other illnesses, Covid-19 can cause enduring problems. Some victims report serious symptoms weeks and months after infection, even many who were never ill enough to be hospitalized. Nearly 100 different long-term problems, detailed in the chart below, were reported to Indiana University Medical School researcher Natalie Lambert, in a survey of more than 1,500 patients. Some of these issues go well beyond typical Covid-19 symptoms.

A top U.S. health official told a U.S. Senate committee on Wednesday that he expects COVID-19 vaccinations to take place over many months and that most Americans could be vaccinated by July of 2021 at the latest.

 

U.S. Centers for Disease Control and Prevention head Robert Redfield said he expects there to be about 700 million doses of vaccines available by late March or April, enough for 350 million people. “I think that’s going to take us April, May, June, you know, possibly July, to get the entire American public completely vaccinated,” Redfield told the U.S. Senate Health, Education, Labor and Pensions Committee.

Researchers from the University of Cambridge used a numerical experiment to determine the limits of matt structural color – a phenomenon which is responsible for some of the most intense colors in nature – and found that it extends only as far as blue and green in the visible spectrum. The results, published in PNAS, could be useful in the development of non-toxic paints or coatings with intense color that never fades.

 

Structural color, which is seen in some bird feathers, butterfly wings or insects, is not caused by pigments or dyes, but internal structure alone. The appearance of the color, whether matt or iridescent, will depending on how the structures are arranged at the nanoscale.

Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbor planet, Venus, has clouds that are temperate but hyperacidic. Here we report the apparent presence of phosphine (PH3) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimeter-waveband spectral detections (quality up to ~15σ) from the JCMT and ALMA telescopes have no other plausible identification.
