The world's oyster reefs could add $12 trillion to planetary health each year—if they were better managed‎

A new study shows that the world's oyster reefs are a precious resource that's vastly underestimated and underutilized. The authors set out to calculate the reefs' potential gross ecosystem product (GEP), the ecological counterpart of the gross economic product, and arrived at trillions of dollars in ecosystem goods and services delivered each year to different aspects of planetary health, including human well-being. But for their full potential to be realized, oyster reefs around the world will need to be restored and protected.

Nobel winner Halzen says years of October 'misery' finally over‎

Physicist Francis Halzen has an impressively long list of academic accolades—but every October, as the Nobel Prize rolled around, his failure to bag the biggest award of them all left him "miserable," he admits.

Computer scientist tracks satellites with automated observatory built from off-the-shelf technology‎

Allen Schnibben's interest in space started when he was a child. "I picked up some books about the solar system when I was in elementary school. In middle school, I got a telescope and I started observing the night sky as a hobby," said Schnibben, a computer scientist at Sandia National Laboratories. "My entire life, I've had an interest in space." Now, Schnibben collects data on satellites at Sandia's SOHBRIT facility, a 12-foot-wide (3.7-meter-wide) observatory.

'Quiet firing' linked to higher levels of 'quiet quitting' among employees‎

A study of the oil, gas and petroleum industry has found that "quiet firing" by employers is associated with higher levels of "quiet quitting" among employees, while strong workplace relationships can weaken that effect. The research appears in the International Journal of Business Information Systems.

Linguists find Madonna's voice defies age-related expectations‎

As women go through menopause, their voices tend to become deeper. This is partly because the vocal folds may swell and the surrounding muscles lose elasticity, resulting in a lower pitch. Age-related physiological changes can also affect the pronunciation of certain vowels.

Nearly 10,000 mapped reactions reveal overlooked steps in CO₂-to-fuel conversion‎

Scientists are increasingly exploring carbon dioxide (CO₂) hydrogenation—where CO₂ reacts with hydrogen over a catalyst to produce products like methanol—to convert CO₂ into useful chemicals and fuels. However, it involves thousands of tiny chemical steps happening on the catalyst surface.

Sorghum may help European agriculture face climate change‎

Research by INRAE and AgroParisTech suggests that global warming could have an overall positive effect on sorghum yields in Europe. Sorghum is a promising alternative to maize in livestock feed. Additionally, the crop requires less water and can tolerate higher temperatures. The researchers carried out simulations that used past climate data and future climate scenarios with the broader goal of developing new strategies for European agriculture. Their results were published in Earth's Future.

New crocodile species discovered in rocks used to build the Great Sphinx‎

A new species of extinct crocodile from Egypt has been discovered, sharing more than just its home with the Great Sphinx. Herugavialis cairensis was found in the very same rocks used to build the iconic monument. And, just as the Sphinx is famously missing the tip of its nose, the fossil crocodile is also missing the tip of its snout.

From coral reef conservation to climate resilience: Turning Indonesia's marine wealth into global impact‎

For Dr. Jamaluddin Jompa, the ocean has never been simply a subject of scientific study. He was born in Takalar, a coastal region of South Sulawesi, Indonesia, and his connection with the sea was forged early. Witnessing the degradation of Indonesia's coastal waters made him wonder: What happens when the ecological relationships that sustain marine ecosystems begin to break down and, more importantly, can they be restored?
