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
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.
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,
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
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.
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.
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
Scientists have produced a first-of-its-kind assessment showing which coastal regions of Europe they believe are at greatest risk from harmful light pollution.
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
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.
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
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.
Herugavialis is the new name for a fossil found in the same rocks that built the Great Sphinx. The reptile is a unique branch of the gharial family tree.
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,
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

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
Transporting material from Earth to the moon is an expensive proposition: By some estimates, moving a single kilogram (2.2 pounds) can cost more than $1 million. Any plan to build a permanent human habitat up there will depend on bringing that sky-high cost down.
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.
Fine particulate matter (PM2.5) is commonly associated with both health concerns and poor visibility. However, these two effects do not necessarily improve or worsen at the same time.
A month after resolving one of the six biggest open problems in mathematics, the company says its new internal model has toppled heaps more—this time without the multimillion-dollar price tag
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

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
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
"Is there enough water? What's happening with climate change? How do I operate my hydro plant? In a world of water problems, there are problems that we need a good model to solve," says Colin Gleason, a hydrologist in the Riccio College of Engineering at the University of
A flash flood can devastate a community for years in a matter of minutes. These disasters account for roughly 85% of floods and cause thousands of deaths annually worldwide, with water levels capable of shooting up 30 feet (9 meters) and receding to normal levels in the span of
Creating a quantum device often begins by intentionally damaging a crystal. Scientists fire an ultrafast laser pulse into a material, knocking atoms out of place and leaving behind tiny imperfections called vacancies. Far from being flaws, these vacancies can behave as
A research team has developed a highly sensitive electrochemical biosensor capable of rapidly and accurately diagnosing cerebrospinal fluid (CSF) leaks that may occur following head surgery or trauma. The team established a diagnostic platform that uses enzymes to detect subtle
The freshwater polyp Hydra oligactis is essentially immortal and reproduces asexually by cloning itself. Except when it gets too cold: then the animal switches to sexual reproduction, begins to age, and eventually dies. A research team at the University of Innsbruck has now
