Study unlocks link between sex and female brain

An international team of scientists led by Gregg Adams at the University of Saskatchewan has discovered that a protein in semen acts on the female brain to prompt ovulation, and is the same molecule that regulates the growth, ...

Researchers program cells to be remote-controlled by light

(PhysOrg.com) -- UCSF researchers have genetically encoded mouse cells to respond to light, creating cells that can be trained to follow a light beam or stop on command like microscopic robots.

New research challenges long-held beliefs about limb regeneration

Ken Muneoka is no stranger to disrupting the field of regeneration; for example, in a 2019 ground-breaking publication in Nature, the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVMBS) professor ...

Lighting the path for cells

ETH researchers have developed a new method in which they use light to draw patterns of molecules that guide living cells. The approach allows for a closer look at the development of multicellular organisms—and in the future ...

Microtubes create cozy space for neurons to grow, and grow fast

Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions ...

Physicists 'turn signals' for neuron growth

(PhysOrg.com) -- A new paper scheduled for publication in the January issue of Nature Photonics describes the use of spinning microparticles to direct the growth of nerve fiber, a discovery that could allow for directed growth ...

FDA approves monoclonal antibody to treat arthritis in cats

Arthritis can keep a cat from doing many of the things that kitties love to do. But now there's hope: The first treatment to ease arthritis pain in cats has been approved by the U.S. Food and Drug Administration.

Hydrogel scaffold helps repair injured spinal cord

Spinal cord injuries can be devastating because the damaged nerves do not regenerate on their own, which often leads to permanent impairment. Scientists have been investigating methods to encourage regrowth, but so far there ...
