Phys.org / Botany's answer to Darwin's finches shows evolution in real time
A new study reveals how a remarkable group of plants on the Galápagos Islands developed their diverse leaf shapes—offering unique insight into evolution at the genetic level. A large international team of researchers has ...
Medical Xpress / A natural molecule boosts CAR-T therapy and turns cold tumors hot
CAR-T cell therapy works well in blood cancers, but many patients still become resistant. A key reason is the presence of CAR-T regulatory T cells (CAR-Tregs), which weaken immune responses. Therefore, selectively targeting ...
Phys.org / Breaking connections helps ideas spread farther, says physics-based study
Sticking with the same people might feel safe and comfortable. But a new Northwestern University study suggests it can actually trap new ideas and behaviors inside tight echo chambers. By contrast, the research, published ...
Phys.org / Embryo epigenome follows universal physical rules, reshaping views of early cell fate
The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined which cells will give rise to which tissues—controlled by epigenetic marks such as DNA methylation. ...
Medical Xpress / A virtual copy of your brain? Scientists say it's closer than you think
For years, the idea of building a working replica of the human brain has lived comfortably in the realm of science fiction. A digital double that could think, learn, or even predict the future of a person's health seemed ...
Phys.org / Antibodies need a strong core—not just grip—to fight SARS-CoV-2
An international research team has identified a previously overlooked factor that influences how antibodies neutralize SARS-CoV-2: their mechanical stability under force. Antibodies are key components of the immune system ...
Medical Xpress / Your nose may be the gateway to a stronger immune system
At the moment, an influenza vaccine called FluMist is the only licensed intranasal vaccine approved for use in humans. The vaccine is administered through a spray of fluid in the nose, rather than with an injection.
Phys.org / Dolls beat screens for building children's social skills, study finds
What's the point of play? Is it simply a way to keep children occupied, or something more? For some, it's about learning literacy and numeracy. For others, it's how friendships form and relationships deepen. But it can be ...
Phys.org / Spintronics at BESSY II: Real-time analysis of magnetic bilayer systems
Spintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and ...
Medical Xpress / A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin
In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...
Phys.org / Sentinel-1D goes live: A milestone for Europe's radar mission
The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase. With all four Sentinel-1 satellites having now been deployed, ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
