Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Arctic ground squirrels changing hibernation patterns
New research analyzes more than 25 years of climate and biological data. The findings include shorter hibernation periods in arctic ground squirrels, as well as differences between male and female hibernation periods.
Research offers clues for potential widespread HIV cure in people
New animal research is helping explain why at least five people have become HIV-free after receiving a stem cell transplant, and may bring scientists closer to developing what they hope will be a widespread cure for the virus that causes AIDS. A new study describes how two nonhuman primates were...
River erosion can shape fish evolution
A new study of the freshwater greenfin darter fish suggests river erosion can be a driver of biodiversity in tectonically inactive regions.
Deep sea surveys detect over five thousand new species in future mining hotspot
There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a...
Deadly virus structures point toward new avenues for vaccine design
By comparing the structures of protein complexes from different lineages of the dangerous Lassa virus, a team identified new antibodies and vaccine targets.
A student’s poor eating habits can lead to a lifetime of illness
A researcher is cautioning that a person's poor eating habits established during post-secondary studies can contribute to future health issues including obesity, respiratory illnesses and depression.
How tasty is the food?
A hormone and specialized brain cells regulate feeding behavior in mice.
Propellers are louder over ground
The effects of the ground on propeller noise have now been measured experimentally.
A look into the heart of cellular waste disposal
Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
