Biodegradable nanoparticle technology may improve agricultural production

Farmers use a manufactured version of a natural plant hormone called gibberellic acid to improve the health and growth of crops, but it is highly sensitive to heat and light. A study in the Journal of the Science of Food and Agriculture shows that loading gibberellic acid into biodegradable nanoparticles can improve grape yield and quality, making it a promising and environmentally friendly approach for sustainable agricultural production.

Fierce lobbying in EU over 'forever chemicals'

The European Union is under pressure to ban "forever chemicals," but a battle is heating up in Brussels over the toxic substances known as PFAS, with industry groups seeking as many exemptions as possible.

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.

A new way to fight gum disease without wiping out good bacteria

Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.

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.

Animals may have evolved 200 million years earlier than we thought

New research suggests animals could have evolved as early as 800 to 700 million years ago, roughly 200 million years earlier than some previous estimates. If so, the first animals may have lived before or during Snowball Earth, leaving behind little trace because their soft bodies were rarely preserved.

What happens in the brain when cannabis makes you anxious?

Cannabinoids may intensify anxiety by removing a natural brake on specific neurons in the brain’s fear center, particularly during stressful situations. In mice, shutting down those neurons sharply reduced cannabinoid-related anxious behavior.

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.
