Phys.org / Tackling the global tuberculosis crisis: An emerging class of antibiotics offers hope
Researchers from the University of Sydney and the Centenary Institute have discovered how a promising class of experimental antibiotics disrupts the bacterium that causes tuberculosis (TB), paving the way for urgently needed ...
Medical Xpress / Jumping 'DNA parasites' linked to early stages of tumor formation
A study published in the journal Science reveals how jumping fragments of human DNA, a type of genetic parasite, destabilize the cancer genome. Unstable genomes are a fertile playground for cancer evolution, giving malignant ...
Phys.org / Birds achieve sweet success: What adaptations to high-sugar diets reveal about metabolism
Anyone who has seen a hummingbird poking her beak deep into a trumpet creeper blossom, or a honeyeater using its brush-tipped tongue to extract nectar from eucalyptus flowers, has witnessed something that, from a human perspective, ...
Phys.org / Ancient mosquitoes developed a taste for early hominins, research reveals
The preference of some mosquitoes in the Anopheles leucosphyrus (Leucosphyrus) group—including those that transmit malaria—for feeding on humans may have evolved in response to the arrival of early hominins in Southeast ...
Medical Xpress / World-first safety guide for public use of AI health chatbots
As members of the public increasingly turn to AI with health concerns, University of Birmingham researchers are leading a global program to build the first definitive guide for safely navigating health information on AI-powered ...
Phys.org / Hair-like rhizoids in liverworts transport phosphorus, shedding light on evolution of roots
Liverwort uses hair-like rhizoids to collect phosphorus from its surroundings and deliver it to where it is needed. This Kobe University discovery sheds light on the evolution of one of the most essential features of land ...
Medical Xpress / Developing a human hepatocyte model with enhanced drug-metabolizing enzyme activity
A research team led by Associate Professor Shinpei Yamaguchi and the late Professor Masako Tada of the Faculty of Science, together with Professor Yojiro Anzai and Lecturer Yohei Iizaka of the Faculty of Pharmaceutical Sciences ...
Phys.org / New technique spots hidden defects to boost reliability of ultrathin electronics
Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms, even the tiniest flaw matters. Researchers at Rice University have shown that hard-to-spot defects ...
Phys.org / Enzymes work as 'Maxwell's demon' by using memory stored as motion
Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and function. Enzymes play a central role in this process, accelerating reactions that would otherwise ...
Phys.org / Vertebrate paleontology has a numbers problem. Computer vision can help
How many fossils does it take to accurately train an image-based AI algorithm? According to a new study co-authored by Bruce MacFadden, UF Distinguished Professor Emeritus and retired curator of vertebrate paleontology at ...
Phys.org / How oxygen enriched Earth's atmosphere 2.5 billion years ago
Cyanobacteria, as they still exist today, were the first organisms to carry out photosynthesis and release oxygen. Produced in primeval oceans about 2.5 billion years ago, this oxygen accumulated in Earth's atmosphere on ...
Phys.org / Immune cells selectively pull DNA from dying nuclei, revealing a process dubbed nucleocytosis
Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm ...
