Restoring African landscapes with indigenous food-bearing trees

Deforestation is a major problem across Africa. It is widely recognized that deforestation harms biodiversity, but tree loss also harms dietary quality, as nutritious fruits, nuts, seeds and leaves disappear from the landscape. More than $1 billion has been pledged for landscape

Hidden dark force may slow cosmic structure growth, not speed it up

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?

New biofilm mechanism in Bacillus cereus could reveal vulnerabilities in food poisoning ba

Scientists from the Department of Microbiology at the University of Malaga, who are also members of the Institute of Subtropical and Mediterranean Horticulture "La Mayora" (IHSM), have discovered a previously unknown mechanism that allows the bacterium Bacillus cereus, which is r

Why South Africa’s leopards shrank to half their normal size

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after

Plasma approach keeps catalysts working for longer in hydrogen production

Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent catalyst deactivation in a key hydrogen production reaction, maintaining stable per

A magnetic field that kills superconductivity can also bring it back

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, but then unexpectedly returns when the magnetic field is

NASA’s Lucy finds a wobbling peanut-shaped asteroid with signs of ancient water

NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight. It also carries traces of ancient water, making it an important clue to the solar system’s mysterio

This common vitamin deficiency can mimic normal aging

Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular p

How bacteria use circadian clocks to colonize their world

Research has revealed how bacteria rely on circadian clocks to control the spread of their multicellular colonies. The findings provide important clues as to how we might improve soil health and plant growth. They may also help explain how some bacteria spread hospital-acquired i

Grade inflation in pandemic strengthened university prospects for private school and disad

The first empirical evidence of how A-level grading in the pandemic affected university applications corroborates concerns about disproportionate benefits for private schools. Disadvantaged students also benefited, however, and the long-term effects for these groups could provide
