Twenty scientists and engineers at the University of Washington are among the 38 new members elected to the Washington State Academy of Sciences for 2021, according to a July 15 announcement. New members were chosen for “their outstanding record of scientific and technical achievement, and their willingness to work on behalf of the Academy to bring the best available science to bear on issues within the state of Washington.”
Current academy members selected 29 of the new members. An additional nine were elected by virtue of joining one of the National Academies.
New UW members who were elected by current academy members are: ....

Atmospheric pollution could be the sign of advanced extraterrestrial civilization

Nitrogen dioxide is part of a group of gaseous air pollutants produced due to road traffic and other fossil fuel combustion processes. In the lower atmosphere (about 10 to 15 kilometers or around 6.2 to 9.3 miles), NO2 from human activities dominate compared to non-human sources. Therefore, observing NO2 on a habitable planet could potentially indicate the presence of industrialized civilization. ....

7 rocky planets orbiting TRAPPIST-1 may be made of similar stuff

The TRAPPIST-1 star system is home to the largest batch of roughly Earth-size planets ever found outside our solar system. Discovered in 2016 some 40 light-years away, these seven rocky siblings offer a glimpse at the tremendous variety of planetary systems that likely fill the universe.
A study accepted by the Planetary Science Journal shows that the planets share similar densities. That could mean they all contain roughly the same ratio of materials thought to be common to rocky planets, such as iron, oxygen, magnesium and silicon. If so, then while the TRAPPIST-1 planets might be similar to each other, they appear to differ notably from Earth: They’re about 8% less dense than they would be if they had the same chemical composition as our planet. ....

"The Red Mirage" --Oldest Planets in the Universe May Suffer Early Heat Death Killing Chance of Life

In the Milky Way Galaxy, about three-fourths of the stars are M dwarfs. But there’s a deadly catch. New research indicates that M dwarfs which are prime targets for astronomers in the search for extraterrestrial life, may have lost their window of opportunity at hosting life because of intense heat during their formative years. M dwarfs, also known as red dwarfs, are the smallest type of hydrogen-burning stars and are the most common stars and the coolest main-sequence stars in the universe.
Planets Billions of Years Old
The possibility of an ancient technological civilization billions of years old is what intrigues astronomers –the heaviest red dwarfs have lifetimes of tens of billions of years, while the smallest have lifetimes of trillions of years into the future. By comparison, the universe is only 13.8 billion years old. These dim red dwarfs will be the last stars shining in the universe. ....
