Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Pesticides significantly affect soil life and biodiversity, study finds
Seventy percent of soils in Europe are contaminated with pesticides. A Europe-wide study co-led by researchers of the University of Zurich now shows that their effects on soil life are substantial, as pesticides suppress ...
Phys.org / Proton-trapping MNene transforms ammonia production for food security and economic growth
With a new electrochemical synthesis via an electrochemical nitrogen reduction reaction (NRR), achieving carbon-free ammonia production is closer to reality through work from Drs. Abdoulaye Djire and Perla Balbuena, chemical ...
Phys.org / Small-scale farmers produce more of the rich world's food than previously thought
Who grows our food? This seemingly simple question is getting harder to answer in a world where our food crosses borders to get to our plate.
Phys.org / Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural ...
Phys.org / A lost world: Ancient cave reveals million-year-old wildlife
Australian and New Zealand scientists have unearthed the remains of ancient wildlife in a cave near Waitomo on Aotearoa's North Island, the first time a large number of million-year-old fossils have been found—including ...
Medical Xpress / Berberine shows no advantage over placebo for reducing liver and belly fat
A multicenter research effort in China conducted clinical trial testing of oral berberine for six months in diabetes-free adults with obesity and metabolic dysfunction-associated steatotic liver disease. Visceral adipose ...
Phys.org / Simple statistical method predicts landslide risk more accurately than classic method
A relatively simple statistical analysis method can more accurately predict the risk of landslides caused by heavy rain, according to a study coordinated by Brazilian researchers affiliated with the Institute of Mathematical ...
Medical Xpress / Targeting the gut's immune system could tackle early stages of Parkinson's
New research reveals how Parkinson's spreads from the gut to the brain, with the help of immune cells—offering a new potential therapeutic strategy—in a study in mice led by scientists at the UK Dementia Research Institute ...
Phys.org / A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands. ...
Phys.org / Novel ferroelectric ultraviolet photodetector achieves near-10,000-fold speed increase
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed a new ferroelectric ultraviolet photodetector material that overcomes the long-standing performance limitations of conventional ...
Medical Xpress / CAR T-cell therapy improves symptoms of myasthenia gravis, clinical trial shows
A new study led by researchers at the UNC School of Medicine and Cartesian Therapeutics, found that immunotherapy can help people with generalized myasthenia gravis, a disease where the body accidentally attacks the cells ...
