It's no secret that Florida's iconic coral reefs are in trouble. Repeated body blows from hurricanes, pollution, disease, climate change—and a near-knockout punch from a 2023 marine heat wave—has effectively wiped several species off the map and shrunk the reefs that stretch
Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.
A new research study found that well-managed fisheries can support the recovery of large marine predators such as seals and porpoises, showing that conservation and sustainable seafood production can go hand in hand. While the impacts of protected species are often debated, the
With already thin profit margins and increasingly uncertain farm labor and other input costs, precision agriculture technology could improve New England's small and medium-sized farms' efficiency, productivity, and resilience. Unfortunately, factors such as up-front costs and
Europa’s subsurface ocean might be getting fed after all. Scientists found that salty, nutrient-rich surface ice can become heavy enough to break free and sink through Europa’s icy shell, delivering essential ingredients to the ocean below. The process is fast, repeatable, and

Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds—structures long considered impossible—the team is opening the door to entirely new kinds
Many species of fungus across the world produce psilocybin, a chemical with psychedelic effects in humans, but its evolutionary purpose may be to deter mushroom-munching insects
The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
A new study suggests humans belong in an elite “league of monogamy,” ranking closer to beavers and meerkats than to chimpanzees. By comparing full and half siblings across species and human cultures, researchers found that long-term pair bonding is unusually common in our
Researchers have identified a promising new weapon against triple-negative breast cancer, one of the most aggressive forms of the disease. An experimental antibody targets a protein that fuels tumor growth and shuts down immune defenses, effectively turning the immune system
Research on using Marchantia polymorpha, commonly known as liverwort, a plant closely related to moss, for food and as an ingredient in medicine and supplements is being conducted at Kobe University.
A new study combines drone data, satellite observations, and ground-based flux measurements to examine methane emissions from ruminants in Kenya. The research represents a pioneering effort to quantify methane (CH₄) emissions from livestock using drones in sub-Saharan Africa.
Colorado will not release more wolves this winter to supplement its reintroduction program after federal officials stopped the planned relocation of wolves from Canada.
Worldwide, it ranks among the cities with the highest levels of air pollution—and it's located in the heart of Europe: Sarajevo, the capital of Bosnia and Herzegovina. Previously, the spatial distribution of air pollutants here was largely unknown, as were their sources. Now
Even as NASA celebrated the rollout of the Space Launch System rocket and Orion spacecraft for Artemis II over the weekend, NASA's new administrator, Jared Isaacman, made sure to put an asterisk on the program's future.

Protein precursors can form in cosmic dust clouds The post Space Dust Could Contain Building Blocks of Life appeared first on Nautilus .
During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother's bloodstream and tissues. They can settle in maternal organs such as the thyroid, liver, lungs, brain and heart—and can persist there for decades.
There's no question that being in nature is good for well-being. Research shows that experiencing nature and listening to natural sounds can relax us.
New University of Hawaiʻi research confirms that "Sharktober" is real, revealing a statistically significant spike in shark bite incidents in Hawaiian waters every October. The study, which analyzed 30 years of data (1995–2024), found that about 20% of all recorded bites
For decades, researchers thought that an October 1843 earthquake on the small Greek island of Chalke caused a powerful tsunami and led to the deaths of as many as 600 people. But a new analysis of primary accounts of the event by Ioanna Triantafyllou at Hellenic Mediterranean
Important everyday products—from plastics to detergents—are made through chemical reactions that mostly use precious metals such as platinum as catalysts. Scientists have been searching for more sustainable, low-cost substitutes for years, and tungsten carbide—an Earth-abundant
According to a new study by the University of Würzburg, Bavarian meadows are the most monotonous insect habitats. Surprisingly, fields and settlements often offer more diversity than grassland.
Whether in the human body or on surfaces, bacteria protect themselves from outside attackers using biofilms. Physicist Eleonora Secchi is researching how these slime-like protective films are formed, with the aim of making it easier to remove pathogenic bacteria.
Africa confronts escalating internal migration and displacement crises fueled by intensifying climate hazards—particularly prolonged droughts—and persistent armed conflicts, which compound vulnerabilities across the continent.
Researchers at University of Tsukuba have developed a cellulose-based composite sheet that integrates paper pulp with starch, polyaniline (a conductive polymer), Prussian blue (a coordination compound), and alginic acid (a natural polysaccharide). These components were
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities have puzzled astronomers for more than 70 years. Now,
Fewer people under age 50 are dying from cancer in the U.S., but colorectal cancer mortality rates continue to surge
Flowers emit scented chemicals to attract pollinators, but this perfume—and how pollinators interact with the plant—can go through profound changes as a crop becomes domesticated.
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process
Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This process, called skeletal editing, can dramatically speed up drug discovery or be applied for upcycling of plastics. Consequently, the field is witnessing
