Phys.org / Migrating charges unlock hard-to-reach C-H bond edits in organic molecules
A team at the University of Vienna, led by chemist Nuno Maulide, has developed a new method for controlling chemical reactions in a more targeted and efficient manner. At the heart of this is the concept of "cation sampling": ...
Phys.org / Field-ready tool identifies rare and zoonotic parasitic worms missed by standard tests
Parasitic nematodes (commonly known as roundworms) are a large, diverse and poorly studied group of disease-causing organisms that severely impact the health of humans and animals. They infect almost one-quarter of the global ...
Phys.org / New shell helps gold nanoparticles keep shape under laser heat longer
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer ...
Phys.org / TriPcides target MRSA, suppress infection and kill dormant bacteria to open a new front against antibiotic resistance
In a new study, researchers show how so‑called TriPcides can target the bacterium Staphylococcus aureus, including antibiotic‑resistant strains such as MRSA. The compounds disrupt the bacteria's ability to cause infection ...
Phys.org / Seabird world shrinks as oceans warm, forcing longer flights to survive
Seabirds such as albatrosses and petrels are retreating into smaller areas of ocean and traveling further to find new places to live as the climate warms. Scientists from the University of Reading studied more than 120 species ...
Phys.org / Brutal field trip provides new insights into Arctic winter
It was the hardest field trip they had ever been on, but the result was both surprising and exciting. After hiking 9 kilometers with a 400-meter elevation gain and carrying heavy backpacks through very rocky terrain, the ...
Phys.org / Proteins that create ice inspire 'cool' applications, from cryomedicine to artificial snow
Bacteria from the Middle East have caused precipitation all the way out in California. The same bacteria, which are known to attack plants, have also been found embedded within lumps of hail in West Africa.
Phys.org / Imperfect polymer sequences still control protein function, revealing new design rules
What happens when a scientific problem seems too complex to solve precisely, yet understanding it could reshape how researchers design new materials and medicines? For decades, much of the polymer science community has relied ...
Phys.org / Decoding the balance between life-and-death proteins
In every organism, the regulation of cell populations is a constant process. This balance relies on a continuous interplay between "guardian" proteins that promote cell survival and "killer" proteins that trigger programmed ...
Phys.org / Bats create 'silent frequency zones' to detect prey in noisy flight, researchers reveal
Sound plays an important role for many animals, helping them navigate and hunt. Echolocation is the ability of animals like bats and dolphins to locate objects by emitting sound waves and interpreting the returning echoes. ...
Phys.org / Grokipedia selectively draws on more-right leaning news sources, says new study
A large-scale analysis of Grokipedia, the world's first AI-written encyclopedia, has found that while many Grokipedia articles closely resemble their Wikipedia counterparts, a substantial subset diverged markedly in style, ...
Phys.org / Molecular net boosts the power of natural biopesticides
Scientists at VIB and Vrije Universiteit Brussel have uncovered a previously unknown mechanism that helps a widely used biological pesticide become more effective. The study, published in Nature Communications, reveals how ...
