Phys.org / Black locust deploys peptides to steer root bacteria into nitrogen fixation
Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial ...
Phys.org / How cricket mothers control the developmental timing of their offspring
Diapause is a fascinating form of biological dormancy employed by a broad array of animals as a survival strategy to endure adverse environmental conditions. To overcome the problems associated with seasons that are unsuitable ...
Phys.org / New findings on how malaria parasites invade human cells yield proof of concept for new antimalarial drug
For nearly half a century, scientists have known that malaria parasites force their way into human red blood cells through a ring-shaped structure called the moving junction. What no one could work out was what it actually ...
Phys.org / The invasive fern that science misidentified for decades
Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present ...
Phys.org / Why some wolves react more strongly to trespassers: Breeders may hold key to scent-based barriers
Wolves use their urine to communicate with each other. A recent study looked at the reactions of a pack to the marking of an intruder. This is a first step toward understanding what attracts or repels canids.
Phys.org / New way to clean up environmental pollution using phage bioaugmentation
The ability of bacteria to remove pollutants from soil, water, mine waste and other environments could be supercharged by a "friendly" compatible virus, according to a study led by Flinders University. The new insights, published ...
Phys.org / Arabian Sea sediments reveal summer and winter monsoons shifted differently after last ice age
High-resolution sediment analyses from the Arabian Sea reveal, for the first time, that summer and winter monsoons respond differently to global climate change. The study enhances understanding of past precipitation patterns ...
Phys.org / 3D genome analysis of germ cell formation tracks 350 million years of vertebrate evolution
A research team led by the Universitat Autònoma de Barcelona (UAB) has revealed how the genome is reorganized in 3D during male germ cell formation in vertebrates, leading to important new insights into how biodiversity is ...
Phys.org / How a sugar building block influences viral attachment
Sialic acid is a natural sugar building block found on the surfaces of our cells. It acts as a protective and recognition molecule and plays a central role in the development of the nervous system. Following the modular principle, ...
Phys.org / AI deciphers long-range DNA signals behind RNA splicing
Accurate RNA splicing is essential for gene expression and human health, yet predicting how DNA sequence variations affect splicing remains a major challenge. Although recent artificial intelligence (AI) models have improved ...
Phys.org / Light-activated compound kills antibiotic-resistant bacteria by turning its own defense enzyme against it
Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria ...
Phys.org / Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition ...
