One of the main proteins that contributes to Alzheimer's disease is called phospho-tau (p-tau). When p-tau gets too many phosphate groups attached to it (a process called hyperphosphorylation), it starts to stick together ...

Animals help disperse seeds and spores for many plant and fungal species. This typically happens when animals eat the fruiting bodies of plants and fungi and pass seeds and spores through their digestive systems.

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, ...

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 ...

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.

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has ...

New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and signals that drive this process. The findings offer important insights into conditions affecting ...

Mars is a dusty planet dominated by vast, dry deserts, with no easily accessible sources of liquid water. Much like on Earth, dust is lifted from Mars's surface by wind and rotating air columns, transported through the atmosphere, ...

Whether you are heading to bed or seeking a midnight snack, you don't need to turn on the lights to know where you are as you walk through your house at night. This hidden skill comes from a remarkable ability called path ...

Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, which is essentially the brain's white matter, was believed to serve the main function of speeding ...

A research team led by Prof. Zhu Min—a member of the Chinese Academy of Sciences (CAS) and affiliated with the CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP)—has identified a new species of fossil ...

Astronomers from the University of Hawai'i (UH) at Manoa and elsewhere have observed the Taurus star-forming region, which resulted in the discovery of planetary-mass and stellar companions of two ultracool dwarf stars. The ...
