A new book examines how far we’ve come in our understanding of the challenges facing our planet.
Results from surveys tracking the true spread of the coronavirus are all over the map—but one done in the heart of the technology sector says the germ is more widespread, and less deadly, than widely believed. The new survey looked for antibodies to covid-19 in the blood of 3,300 residents of Santa Clara County, which is home to Palo Alto, top venture capital firms, and the headquarters of...
Five days before NASA's Spitzer Space Telescope ended its mission on Jan. 30, 2020, scientists used the spacecraft's infrared camera to take multiple images of a region known as the California Nebula—a fitting target considering the mission's management and science operations were both based in Southern California at NASA's Jet Propulsion Laboratory and Caltech. This mosaic is made from those...
In a paper published in Science Advances, an international team of researchers have examined traits of marine megafauna species to better understand the potential ecological consequences of their extinction under different future scenarios.
Early treatment with the experimental antiviral drug remdesivir significantly reduced clinical disease and damage to the lungs of rhesus macaques infected with SARS-CoV-2, the coronavirus that causes COVID-19, according to National Institutes of Health scientists.
NASA and SpaceX have set a date for the first crewed space mission to be launched into orbit from U.S. soil since the space shuttle fleet's retirement nearly nine years ago. SpaceX's Falcon 9 rocket is due to launch NASA astronauts Bob Behnken and Doug Hurley inside a SpaceX Crew Dragon spaceship at 4:32 p.m. ET (1:32 p.m. PT) May 27, sending them to the International Space Station for an...
Ron Kim was already convinced that money should be redesigned. Now that the coronavirus epidemic has hit, he’s doubling down. Before covid-19 started spreading in the United States, Kim, a New York assemblyman who represents a district in Queens, had been pushing for the state to create a publicly run digital payment system. He and other proponents described the concept as a sort of...
(Bloomberg) — Elon Musk’s SpaceX will fly American astronauts to the International Space Station on May 27, according to National Aeronautics and Space Administration Administrator Jim Bridenstine, setting an official launch date for the mission. The launch, which Bridenstine announced in a tweet on Friday, will mark the first for NASA astronauts from American soil to the orbiting lab...
NASA announced on Friday that a SpaceX rocket will send two American astronauts to the International Space Station in May, the first manned US spaceflight in nearly a decade.
Scientists have theorized that organometallic halide perovskites— a class of light harvesting "wonder" materials for applications in solar cells and quantum electronics— are so promising due to an unseen yet highly controversial mechanism called the Rashba effect. Scientists at the U.S. Department of Energy's Ames Laboratory have now experimentally proven the existence of the effect in bulk...
Impact cratering both produces new regolith and causes seismic events that can degrade and erase small craters on the surface of asteroids, a paper by Planetary Science Institute Senior Scientist James Richardson says.
For millennia, metallurgists have been meticulously tweaking the ingredients of steel to enhance its properties. As a result, several variants of steel exist today; but one type, called martensitic steel, stands out from its steel cousins as stronger and more cost-effective to produce. Hence, martensitic steels naturally lend themselves to applications in the aerospace, automotive and defense...
Today, NASA announced that its crewed SpaceX flight will launch on May 27th, The Washington Post reports. The flight will mark the first astronaut launch from US soil since 2011, and it will be the first SpaceX flight carrying passengers, not just...
Data privacy laws require encryption and, in some cases, transforming the original data to 'protected data' before it's released to external parties.
Researchers have synthesized nanoparticles that can be induced by a change in pH to release a deadly dose of ionized iron within cells. This mechanism could potentially open up new approaches to the targeted elimination of malignant tumors.

Andrew Ng’s startup Landing AI has created a new workplace monitoring tool that issues an alert when anyone is less than the desired distance from a colleague. Six feet apart: On Thursday, the startup released a blog post with a new demo video showing off a new social distancing detector. On the left is a feed of people walking around on the street. On the right, a bird’s-eye diagram...

Researchers at the University of Illinois at Urbana-Champaign have used molecular dynamics simulations to understand how sodium dodecyl sulfate causes protein unfolding. SDS is commonly used in labs to separate proteins and determine their molecular weights. However, it is still unclear how SDS influences protein structure.
After a wild couple of months of equity market volatility, many mutual fund investors are now cautiously exploring how best to rebalance their portfolios. As they do so, new research from the McCombs School of Business at The University of Texas at Austin says they should keep an important factor in mind: taxable capital gains.
Inspired by how human bone and colorful coral reefs adjust mineral deposits in response to their surrounding environments, Johns Hopkins researchers have created a self-adapting material that can change its stiffness in response to the applied force. This advancement can someday open the doors for materials that can self-reinforce to prepare for increased force or stop further damage. A report of...
