Siberian hamsters show what helps make seasonal clocks tick
Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping ...
Stretchable lithium-ion battery can twist, bend, return to normal shape (w/ Video)
(Phys.org)—Northwestern University's Yonggang Huang and the University of Illinois' John A. Rogers are the first to demonstrate a stretchable lithium-ion battery—a flexible device capable of powering ...
Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
Immortal worms defy aging
Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal.

Crucial new insight into the secrets of Nobel Prize-winning pump
The story of the sodium-potassium pump has strong ties to Denmark. In 1997, the Danish scientist Jens Chr. Skou received the Nobel Prize in Chemistry for his discovery, and over the years, research on the ...
Decoding mystery sequences involved in gene regulation
Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...
By keeping the beat, sea lion sheds new light on animals' movements to sound
A California sea lion who bobs her head in time with music has given scientists the first empirical evidence of an animal that is not capable of vocal mimicry but can keep the beat, according to new research ...
Sexually naive male mice, fathers respond differently to pups
Sexually naïve male mice respond differently to the chemical signals emitted by newborn pups than males that have mated and lived with pregnant females, according to a study published March 20 in The Journal of ...
Colleges say federal cuts could cause brain drain
At the Massachusetts Institute of Technology, faculty fret about the future of the school's Plasma Science and Fusion Center. Thirty miles (fifty kilometers) away, administrators at the state university campus ...
Carbon nanotubes lower nerve-damaging chloride in cells
A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury.
A direct line through the brain to avoid rotten food—a full STOP signal for Drosophila
Consuming putrid food can be lethal as it allows bacterial pathogens to enter the digestive system. To detect signs of decay and thus allowing us and other animals to avoid such food poisoning is one of the ...
Study tracks brain gene response to territorial aggression
With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away.
New study finds evolution mostly driven by brawn, not brains
The most common measure of intelligence in animals, brain size relative to body size, may not be as dependent on evolutionary selection on the brain as previously thought, according to a new analysis by scientists.
