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.

Humans may not be as hardwired for violence as we thought

A study comparing 100 primate species, including humans, suggests that everyday aggression and lethal violence did not evolve as part of the same simple behavioral spectrum. Species that frequently fight or show mild aggression are not necessarily more likely to kill rivals, while extreme acts such as infanticide and lethal attacks appear to follow their own evolutionary patterns.

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.

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.

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?

Crystal alignment explains why magnesium alloy plates resist ballistic impacts better in one direction

Magnesium (Mg) alloys offer a pathway to lighter, more efficient aerospace and defense structures because of their low density, high specific strength and excellent damping capacity. However, their hexagonal close-packed (HCP) crystal structure makes deformation highly dependent on crystallographic orientation.

Chernobyl particles reveal unexpectedly stable nuclear fuel after 40 years

Chernobyl particles reveal unexpectedly stable nuclear fuel after 40 years

Four decades after the 1986 nuclear disaster, researchers at Leibniz University Hannover and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) examined six tiny, highly radioactive fragments that were released from the destroyed reactor in Ukraine in the wake of the incident. Analyses show that these "hot particles" are far more stable than had previously been assumed. The findings could allow for more precise assessments of the health risks posed by such radioactive particles. The paper is published in the Journal of Hazardous Materials.

Hydrothermal vents supply a geochemical precursor of ATP that could have powered early life

Where did the energy come from to power the chemical origin of life, and how did phosphate come to be the universal energy currency of cells? Biologists from the Institute of Molecular Evolution at Heinrich Heine University Düsseldorf (HHU) have uncovered a new source of energy that drove primordial chemical reactions on the early Earth forward to kick-start metabolism. Their findings, now published in The FEBS Journal, identify phosphite and palladium, substances that naturally occur in H2-producing hydrothermal vents, as an inorganic precursor of ATP.

Young infants see saliva sharing as a sign of a close bond, experiments suggest

Imagine you're an infant. Just a few months in the world, trying to gather your faculties, testing gravity—you're pretty helpless and fully reliant on the people around you. As a result, one of your primary tasks as a new person—even before hand-eye coordination and responding to your own name—is to figure out how the people you've just met are connected to each other.

Tetrahedral iron can help clays exchange electrons about ten times faster

Smectites are clay minerals that can contain large amounts of structural iron. Unlike iron oxides, they do not dissolve when their iron is reduced, so they can be reduced and reoxidized many times. This makes them a recyclable pool of redox-active iron that supports microbial respiration, transforms contaminants and influences nutrient and trace element cycling.
