Researchers identify MANF as a rejuvenating factor in parabiosis

Older mice who are surgically joined with young mice in order to share a common bloodstream get stronger and healthier, making parabiosis one of the hottest topics in age research. Publishing in Nature Metabolism, researchers from the Buck Institute report that MANF (mesencephalic astrocyte-derived neurotrophic factor) is one of the factors responsible for rejuvenating the transfused older mice.

Study explores energetics and stride variability during gait transition in mammals

A dog's gait, according to the American Kennel Club, is "the pattern of footsteps at various rates of speed, each distinguished by a particular rhythm and footfall." When dogs trot, for example, the right front leg and the left hind leg move together. This is an intermediate gait, faster than walking but slower than running.

New research collaboration launches first evolutionary study to explore origins of fish that walk

A new research collaboration with support from the National Science Foundation, or NSF, begins an unprecedented study of walking cavefish to better understand the "fin-to-limb" transition that enabled the first vertebrates to walk on land more than 350 million years ago.

UI study leads to better understanding of signaling capacity between neurons

The fundamental process of information transfer from neuron to neuron occurs through a relay of electrical and chemical signaling at the synapse, the junction between neurons. Electrical signals, called action potentials, cause voltage-gated calcium channels on the presynaptic neuron to open.

Study sheds new light on disease-spreading mosquitoes

When the West Nile virus (WNV) was initially isolated in two patients at a Queens, N.Y., hospital in the summer of 1999, it would have been hard to anticipate how quickly one common species of house mosquito, Culex pipiens, would help begin to spread the virus throughout the western hemisphere.

Eliminating microglia can reverse some aspects of stress sensitization, study shows

Using an animal model of chronic stress, researchers at The Ohio State University have shown that the immune cells of the brain, called microglia, hold unique signatures of chronic stress that leave the animal more sensitive to future stressful experiences, evident by increased anxiety and immune responses.

Researchers develop new technique to accurately isolate phloem cells across plants

Crops worldwide are increasingly vulnerable to pandemics, as diseases hitch rides on global flows of people and goods, hopping from continent to continent. Phloem diseases such as citrus greening are one particularly devastating group of plant diseases that have been wreaking economic havoc globally.
