Phys.org / Light-activated protein illuminates when embryos can cope with disruptions to cell division
Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to divide quickly to enable rapid growth, but it's important not to introduce errors that could be fatal ...
Phys.org / Malaria parasite sneaks mRNA into immune cell nuclei, disrupting defenses
RNA technology is regarded as one of the newest frontiers in medicine, but in fact a primordial innovator got there way before we did. The malaria parasite, an ancient single-celled organism, has been using sophisticated ...
Medical Xpress / Scientists recruit red blood cells to deliver genetic cargo with instructions to kill cancer
Scientists have developed a way to turn the body's own immune cells into cancer-fighting agents—without removing them from the body—by using red blood cells to deliver genetic instructions. Current CAR (chimeric antigen receptor) ...
Phys.org / Gene circuits reshape DNA folding and affect how genes are expressed, study finds
When a gene is turned on in a cell, it creates a ripple effect along the DNA strand, changing the physical structure of the strand. A new study by MIT researchers, appearing in Science, shows that these ripples can stimulate ...
Science X / Snowball Earth may hide a far stranger climate cycle than anyone expected
During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In Snowball Earth models, the ...
Phys.org / Kangaroos chart 'upside-down' evolution
New research led by Flinders University argues thick tooth enamel helped kangaroos chart an unconventional evolution story, compared to the animals of other continents. A 50-million-year natural "experiment" among Australia's ...
Phys.org / Oldest burial in Patagonia reveals early human settlement along South America's Atlantic coast
The peopling of South America has long been debated, with various routes proposed for how they spread across the subcontinent. However, routes along the Atlantic coast were typically much younger than their Pacific counterparts, ...
Phys.org / Superconducting quantum circuit simulates proton tunneling phenomenon in chemical systems
Researchers at Yale, Google, and the University of California-Santa Barbara have created a device that simulates the quantum "tunneling" behavior of protons that occurs in chemistry, a process so common it occurs in everything ...
Medical Xpress / Why this CAR T advance matters: Complete remissions without chemotherapy at doses as low as 250,000 cells/kg
Stem-cell memory T (TSCM) cells are a rare subset of immune cells with the ability to self-renew, persist long term, and mount potent anti-tumor responses. These properties make them an attractive candidate for next-generation ...
Phys.org / Fungi utilize ancient antimicrobial proteins to attack hosts and their microbiomes, plant researchers discover
An international research team led by Cologne-based plant scientist Professor Dr. Bart Thomma from the Institute for Plant Sciences, the Collaborative Research Center MiBiNet and the CEPLAS Cluster of Excellence for Plant ...
Phys.org / Buried in soil, a 100-million-year-old bacterial toxin could reshape pest control and antibiotic discovery
In every backyard, park, and playground on Earth, the ground is teeming with a type of bacteria called Streptomyces—one of the most abundant organisms on the planet. While these dirt-dwelling microbes are known for producing ...
Phys.org / A hidden food boom across Central Africa is pushing wildlife and rural diets toward a precarious edge
The total annual biomass of wild meat consumed across Central Africa has increased from an estimated 0.73 million metric tons in 2000 to 1.10 million metric tons in 2022. This increase is threatening wildlife populations ...
