Smart roof coating uses physics trick to warm or cool the house, depending on the season
Posted by Shane Hinshaw in categories: habitats, physics
Rooftop coatings can keep homes cool — like cooling paper that helps radiate heat away. Or they can trap heat inside, keeping homes warm.
But what is the optimal rooftop coating for homes with both a hot and cold season?
Scientists have come up with an answer: an all-season covering that keeps homes warm in the winter and cool in the summer.

Is Society in General Turning its Back on Intellectual Discussion and Scientific Discovery?
Posted by Len Rosen in categories: biotech/medical, existential risks
In our global struggle to deal with COVID-19 and the existential threat that is climate change, there is a growing anti-intellectual, anti-science movement afoot.
Is 21st-century civilization following Rome and China as we turn to disinformation delivered by the technologies science has fostered?

Scientists develop powerful family of 2D materials
Posted by Shailesh Prasad in categories: materials, nanotechnology
A team from the Tulane University School of Science and Engineering has developed a new family of two-dimensional materials that researchers say has promising applications, including in advanced electronics and high-capacity batteries.
Led by Michael Naguib, an assistant professor in the Department of Physics and Engineering Physics, the study has been published in the journal Advanced Materials.
“Two-dimensional materials are nanomaterials with thickness in the nanometer size (nanometer is one millionth of a millimeter) and lateral dimensions thousands of times the thickness,” Naguib said. “Their flatness offers unique set of properties compared to bulk materials.”

On Longevity Escape Velocity with Aubrey de Grey & Charles Brenner
Posted by Montie Adkins in categories: biotech/medical, life extension
For our inaugural episode of Let’s Talk Longevity, we want to figure out if we are anywhere near Longevity Escape Velocity. Defined as a hypothetical situation in which life expectancy is extended longer than the time that is passing, we decided the best conversation on it would be with its biggest advocate, Dr. Aubrey de Grey, and an equally well-known skeptic of the likelihood of it taking place, Dr. Charles Brenner. This debate did not need hosts!
Join us for the live Q&A on Twitter Spaces this Thursday, May 12th at 12 pm PDT

After losing contact with its helicopter, NASA put the entire Mars mission on hold
Posted by Alberto Lao in category: space
Well, happily, Ingenuity did call home after about 24 hours. According to NASA, the link was stable, and the solar array managed to charge its batteries to 41 percent. The engineers say they hope to resume Ingenuity’s flight campaign within the next several days after bringing the helicopter’s batteries to a full charge.
Unfortunately, this may be the beginning of the end for a helicopter that has vastly exceeded all expectations. The NASA engineers have had to take some fairly drastic steps to preserve Ingenuity’s battery charge. For example, they have now commanded the helicopter’s heaters to come on only when the battery’s temperature falls to −40°, far colder than the previous point of 5° Fahrenheit. It is not known how many of the off-the-shelf components on the vehicle will fare without this additional heating during the cold Martian nights.
And Mars will only get colder and darker for the next 10 weeks as winter deepens.
