Phys.org / 3D analysis of wrist ligaments reveals locomotion clues in human ancestors
When studying how fossil hominids moved, researchers usually analyze the morphology of bones—which is crucial for understanding the evolution of bipedalism—focusing mainly on muscle insertion sites. However, the potential ...
Phys.org / Living rocks in South Africa rapidly absorb carbon and grow in harsh conditions
South Africa is home to some of the oldest evidence of life on Earth, contained in rocky, often layered outcroppings called microbialites. Like coral reefs, these complex "living rocks" are built up by microbes absorbing ...
Medical Xpress / Astrocytes found to aid spinal cord repair by signaling immune response
Cedars-Sinai investigators have discovered a healing mechanism that could one day be harnessed to help treat patients with spinal cord injuries, stroke, and neurological conditions such as multiple sclerosis. Their study, ...
Phys.org / Engineered proteins enable smartphone-based detection of specific DNA sequences
Imagine a container of tomatoes arriving at the container terminal in Aarhus. The papers state that the tomatoes are from Spain, but in reality, we have no way of knowing if that is true.
Phys.org / Webb observes pulsar-orbiting planet whose composition defies explanation
Scientists using NASA's James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed.
Medical Xpress / Individual genetic differences can render some antibody-based therapies ineffective
Antibody-based therapies are used to treat numerous diseases, from cancer to rheumatic disorders and multiple sclerosis. Antibodies recognize and bind to very specific structures. This allows them to direct active substances ...
Phys.org / Biologists reveal ancient form of cell adhesion
The cells of all animals—including humans—are characterized by their ability to adhere particularly well to surfaces in their environment. This mechanically stable adhesion enables the development of complex tissues and ...
Medical Xpress / Liver cell reprogramming boosts T cell function in aging immune systems
As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as quickly, making people more susceptible to a variety of infections.
Phys.org / Scientists develop a smarter mRNA therapy that knows which cells to target
Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells—an advance demonstrated in studies in mice ...
Phys.org / Drone-mounted lab monitors fertilizer runoff in real time
What if, instead of taking a water or soil sample to the lab, you could take the lab to the sample? That's what a team of researchers reporting in ACS Sensors did with a new nitrate-monitoring "lab-on-a-drone" system. The ...
Tech Xplore / Confined crystallization strategy improves spray-coated perovskite device performance
Metal halide perovskites are promising for next-generation high-efficiency photovoltaic and optoelectronic devices due to excellent tunable properties and solution processability. Recent fabrication techniques (such as spin ...
Phys.org / Why do wombats have square poop?
Most people have a preferred way of communication—phone, text, email—but bare-nosed wombats have an unusual way of relaying information.
