Sitting in his narrow dugout canoe, Jean-Romeo Senguemboli frowned at the meager catch in his nets on the Central African Republic's Mbali River, where experts say deforestation is devastating the fish population.

Losing more ground in the fight against climate change, humanity is heading for a hotter world than experts projected last year—and the United States is a big reason for that, a new United Nations report says.
Nearly all metabolic processes require protons—positively charged hydrogen atoms. Although these are abundant in the cellular fluid, the biocatalysts involved depend on mechanisms for efficiently capturing protons and transporting them to the site where catalysis occurs. Enzymes
OCD is a mental health disorder characterized by unwanted, recurring thoughts and repetitive behaviors that can severely interfere with everyday life. Exposure-based psychotherapy is one of the most effective treatments, but the biological mechanisms underlying treatment response
Developing stronger and tougher structural metals such as steel requires exploring an enormous range of processing conditions. Even for the same alloy composition, heat treatment can dramatically change the material's microstructure and mechanical properties. If there were a way
Skeletal muscles grow and regenerate as individual precursor cells—called myoblasts—fuse into long fibers from which mature muscle fibers develop. How they coordinate this process and form functional muscles is not yet fully understood. A research team at the Max-Planck-Zentrum f
The growth and death of cancer cells in the lab are studied primarily in two-dimensional cell cultures. In a study published in the journal Developmental Cell on Oct. 14, researchers instead used three-dimensional models to uncover how pressure and mechanical confinement impact c
Quantum networks are systems that connect different users or devices using principles of quantum mechanics. In the future, these networks could help improve the security of communications.
Quantum physicists trace a century of controlling spin and more — today's mech signal.
A concept from the field of quantum mechanics, spin is a property of particles that has no direct counterpart in everyday experience. Since the early 20th century, researchers have learned to manipulate it deliberately by means of precisely shaped electromagnetic pulses. This has
New research has revealed an unexpected new mechanism through which the killer fungus Candida auris is resisting antifungal drug treatment. A team led by the University of Exeter and City St George's, University of London, discovered that the fungus creates multiple versions of i
Researchers at Gladstone Institutes have uncovered an unusual bacterial immune system that operates in reverse of known defenses. The discovery, published in Molecular Cell, details the mechanics of "type VI retrons"—a counterintuitive class of bacterial defenses. More than just
Climate change can look very different at the scale of a forest, field or hillside. A new review shows how changes in vegetation and atmospheric conditions can cause local microclimates to warm at very different rates from the regional climate—and why this matters for understandi
Migrating birds that breed in the Arctic are spreading avian influenza to polar bears in eastern Greenland, according to a new study that found evidence of infections in bear blood samples acquired from Greenland Inuit subsistence hunters.
Scientists have proposed what they believe is the first method for detecting "mirror life"—a hypothetical form of life made from molecular building blocks that are the mirror image of those found naturally on Earth. Researchers at the University of Strathclyde and the Department
A shark that has become a viral sensation in South Korea was coaxed out of a canal in which it was stuck, authorities said on Wednesday, as falling temperatures raised concerns for its survival.
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team of researchers in Japan might have found a solution. In
Scientists from RMIT University and Riga Technical University in Latvia have shown that static charge left on surfaces can be controlled, which may have big benefits for companies needing to avoid the little zap in production of common household goods. The discovery could even on

Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for membraneless compartments inside cells and for "protocel
An international study led by the Institute of Evolutionary Biology (IBE, CSIC-UPF) in Barcelona, the Natural Sciences Museum of Barcelona, Harvard University and the University of the Basque Country (EHU) has reconstructed the genetic history of the Iberian Peninsula between the
Moderately cold temperatures have proven to effectively extend lifespan and delay age-related decline in animals. However, how cold temperatures trigger these beneficial effects at the molecular level has remained largely unclear.
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. In a study published in Nature, scientists at Albert Einstein College of Medicine and collabo
