For resetting circadian rhythms, neural cooperation is key
Fruit flies are pretty predictable when it comes to scheduling their days, with peaks of activity at dawn and dusk and rest times in between. Now, researchers reporting in the Cell Press journal Cell Reports on April 17th h ...
How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
How does complex behavior spontaneously emerge in the brain?
The circadian clock is like an orchestra with many conductors
You've switched to the night shift and your weight skyrockets, or you wake at 7 a.m. on weekdays but sleep until noon on weekends—a social jet lag that can fog your Saturday and Sunday.
Brain process takes paper shape
A paper-based device that mimics the electrochemical signalling in the human brain has been created by a group of researchers from China.
Fighting flies: Biologists identify sex-specific brain cells in male flies that promote aggression
(Phys.org) —When one encounters a group of fruit flies invading their kitchen, it probably appears as if the whole group is vying for a sweet treat. But a closer look would likely reveal the male flies ...
Discovery of quantum vibrations in 'microtubules' corroborates theory of consciousness
A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent ...
Nanoscale 'tsunami' helps locusts tune in
The remarkable mechanism by which the tiny ears of locusts can hear and distinguish between different tones has been discovered by researchers from the University of Bristol.
Single-cell genome sequencing gets better
Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. The breakt ...
Glowing worms illuminate the roots of behavior
A research team at Worcester Polytechnic Institute (WPI) and The Rockefeller University in New York has developed a novel system to image brain activity in multiple awake and unconstrained worms. The technology, ...
Key cellular mechanism in the body's 'battery' can either spur or stop obesity
Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body's energy-producing "battery," according to two new studies by Yale School of Medicine researchers featured as the ...
Researchers apply brainpower to understanding neural stem cell differentiation
How do humans and other mammals get so brainy? USC researcher Wange Lu, PhD, and his colleagues shed new light on this question in a paper that will be published in Cell Reports on October 24.
Juvenile mice secrete a protective pheromone in their tears, blocking adult mating
Nocturnal animals need their noses to stay alive. Mice, among others, depend on their impressive olfactory powers to sniff out food or avoid danger in the dark.
Scientists describe how mosquitoes are attracted to humans
Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to us by smelling the carbon dioxide we exhale, being capable of tracking us ...
