Toxic gas released by ancient microbes may have worsened Earth’s largest mass extinction

Dominik Hülse, an Earth system modeler based at University of California Riverside, worked on a November 2021 study that explored how ancient microbes may have prolonged the Permian extinction by producing a toxic gas. Here, Hülse poses with a finger to his nose to highlight the toxic “rotten egg” scent of hydrogen sulfide. (Image credit: … Read more

People Have Been Having Less Sex–whether They’re Teenagers or 40-Somethings

What Antarctica’s ‘Doomsday’ Glacier Could Mean For The World

The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier hemorrhages more and more ice.   Adding 65cm to global sea levels would be coastline-changing amounts. For context, … Read more

Recycled Tennis Balls Could Protect Buildings from Earthquakes

Earthquakes cannot be forecast, but engineers can prepare for them. Seismic-isolation systems built into the bases of certain buildings in high-risk areas, such as San Francisco’s City Hall, use complex structures of concrete, rubber and metal to reduce quake damage by absorbing the ground’s horizontal oscillations, like a car’s suspension does with vertical motion. But … Read more

Will Congress deliver big funding boosts for science? Here’s your guide | Science

Congress came very close to giving U.S. researchers a funding windfall in 2021. But the Democrats’ narrow majority in both houses and a united Republican opposition doomed efforts to pass three major pieces of legislation, each one containing billions of dollars for research. However, science advocates are cautiously optimistic that lawmakers, who return to work … Read more

This 19th Century ‘Eco-Villain’ Made Space Art That Was Truly Ahead of Its Time

Astrophotography allows us all to become citizens of the cosmos.  At a glimpse, we can be transported into the depths of space to gaze upon Jupiter’s dazzling cloudscape. Moments later we can picture the shifting rust-colored sands of Mars, or navigate our way across the lunar surface.   It’s a gift that’s easy to take … Read more

The Weirdest Eyes in The Animal Kingdom See a World We Can’t Imagine

When you view the world a certain way, it’s easy to forget not everyone has the same vision. We do mean that quite literally. Aside from philosophical considerations of the subjective experience of color, different organisms have evolved to view the world differently, with eye structures and configurations optimized for various kinds of existence.   … Read more

NASA delays tightening James Webb Space Telescope sunshield to study power system

NASA personnel are spending the day studying the power subsystem of the massive James Webb Space Telescope to ensure the observatory is ready to execute a key procedure: tensioning its vast sunshield. The Webb space telescope, which launched on Dec. 25, is conducting a month-long deployment procedure necessary to prepare the telescope to gather data. … Read more

The Weight Game: How Body-Size Bias Can Hold Back Health Science

In December 1994 then former U.S. surgeon general C. Everett Koop launched a national weight-loss campaign at a White House press conference, stating that obesity had become the country’s second-largest cause of death, “resulting in about 300,000 lives lost each year.” This marked the beginning of a long, influential life for the statistic. Pundits and … Read more
