The Simons Foundation today announces that David Spergel, an accomplished astrophysicist and winner of the prestigious Breakthrough Prize, will be the foundation’s next president, effective July 1, 2021. Spergel currently serves as director of the Center for Computational Astrophysics at the Simons Foundation’s Flatiron Institute in New York City.
People with diabetes — especially the 20 to 40 percent with diabetic kidney disease — are among the most at risk for serious complications and death from COVID-19. A new study of gene expression utilizing machine learning peered inside the kidney cells of COVID-19 patients and diabetic kidney disease patients and made a surprising discovery: Similar molecular processes were activated in both sets of patients, revealing potential avenues of viral vulnerability. The researchers report their findings in Kidney International.
You can’t understand the universe unless you understand the galaxies that comprise it. Galaxies are home to stars, black holes, dark matter halos and clouds of gas and dust. But insights into these galactic phenomena aren’t easily obtained. Astrophysicists have long struggled to develop a complete view of galaxies that spans the entire cosmic scale, from single stars to superclusters of thousands of galaxies.
For decades, scientists have hunted for materials in which electrons flow without resistance. Until recently, this hunt focused squarely on superconductors, in which electrons pair off and flow freely. But superconductors aren’t the only game in town. In 2013, for the first time scientists observed a phenomenon known as the quantum anomalous Hall (QAH) effect. Just like in a superconductor, electrons under the QAH effect flow without dissipating energy, albeit via a different mechanism. Now a new material is pushing the QAH effect to new limits, dramatically increasing the temperature and conditions in which the effect occurs.
The Blavatnik Family Foundation and the New York Academy of Sciences have named computational astrophysicist Adrian Price-Whelan as the winner of the 2020 Blavatnik Regional Award for Young Scientists in the physical sciences and engineering category. The award recognizes outstanding postdoctoral scientists from academic research institutions in New York, New Jersey and Connecticut, and comes with a $30,000 prize.
An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable — a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining four cutting-edge methods finds that the modest material boasts fantastic and surprising quantum properties.
Astrophysicist Brian Metzger has been named the 2020 Blavatnik National Awards Laureate in Physical Sciences & Engineering by the Blavatnik Family Foundation. The honor recognizes Metzger’s contributions to the discovery of the origins of gold and other heavy elements in the universe. The $250,000 prize is one of the largest for early-career scientists.
Even by the standards of quantum physicists, strange metals are just plain odd. The materials are related to high-temperature superconductors and have surprising connections to the properties of black holes. Electrons in strange metals dissipate energy as fast as they’re allowed to under the laws of quantum mechanics, and the electrical resistivity of a strange metal, unlike that of ordinary metals, is proportional to the temperature.
From a mountain high in Chile’s Atacama Desert, astronomers with the National Science Foundation’s Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in the universe. Their new observations plus a bit of cosmic geometry suggest that the universe is 13.77 billion years old, give or take 40 million years.
Led media push for newest findings from the Atacama Cosmology Telescope, coordinating with dozens of other institutions. Media coverage in New Scientist, Science News, BBC, Nature, USA Today, UPI and Express.
Neurons that regularly remodel are more prone to Alzheimer’s disease and die when that remodeling goes awry, a new study suggests. The work is the first to track the progression of Alzheimer’s at the genetic and molecular levels within neurons vulnerable to the disease.
