Medical Xpress / Scientists decipher how T cells sense enemies—such as cancer—at point of contact
Every encounter between a T cell and a potential target—especially when that target is a developing tumor—begins with a rapid series of molecular decisions. Within seconds, the immune cell must determine whether to launch ...
Phys.org / Chicxulub's lingering dust may have turned falling debris into a global firestorm
Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico's Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that ...
Phys.org / Psychologist develops puzzle that can tell you how fast you think
A puzzle that can tell players how fast they think on their feet has been developed by a University of Leeds researcher.
Phys.org / More evidence Mars once had water emerges from old Spirit rover data
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
Tech Xplore / Insect-inspired electronic nose: Turning semiconductor chips into olfactory sensors
Bioengineers at the University of California San Diego integrated the olfactory receptor of an insect called a jumping bristletail into semiconductor chips made of graphene, creating an electronic nose capable of sniffing ...
Tech Xplore / Hidden battery flaw may shorten EV lifespans
As the need for sustainable electric vehicles grows, cobalt-free, high-nickel cathode batteries (such as manganese-coated nickel-core batteries) have emerged as one of the most promising technologies. These batteries increase ...
Phys.org / 'Rivers in the sky' influence marine heat waves
Long, narrow bands of moving moisture in the sky, known as atmospheric rivers, contribute to heat waves in the marine environment, according to a new study published in Nature Communications by researchers from Duke University's ...
Tech Xplore / Waste-based geopolymer mortar offers greener, fire‑resistant alternative to conventional concrete
Concrete ranks second among the most widely used materials on the planet and is regarded as highly versatile for climate-resistant infrastructure. However, the main ingredient of concrete is Portland cement, which is made ...
Tech Xplore / Future-aware AI doubles robot speed in pick-and-place tasks
A new method developed by MIT researchers makes robots better at thinking ahead while they are acting, leading to smoother motions and quicker reactions. The research is published on the arXiv preprint server.
Phys.org / AI finds tiny gene editor changes that reduce unintended DNA edits
Gene editing is a highly precise and powerful technology that allows scientists to insert, delete, modify or replace DNA bases in living organisms. It has a variety of uses, including correcting disease-causing mutations ...
Phys.org / Small ants that evict coffee pests may gain reproductive boost while protecting crops
Ants are known allies in the fight against coffee pests known as coffee berry borers. Now, a discovery made by Jonathan "Jonno" Morris while he was a University of Michigan graduate student has revealed there may be a new ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
