Research identifies how snowshoe hares evolved to stay seasonally camouflaged
Many animals have evolved fur or feather colors to blend in with the environment and hide from predators. But how do animals stay camouflaged when their environment changes with each new season? Researchers at the University ...
Researchers create matchmaking service for peptides and antibiotics
UBC researchers have matched small proteins, called peptides, with antibiotics so they can work together to combat hard-to-treat infections that don't respond well to drugs on their own.
Mice not only experience regret, but also learn to avoid it in the future
Experiencing regret can leave a "bad taste" in one's mouth and drive an individual to compensate for one's losses. This immediate post-regret phenomenon was once thought to be unique to humans, but it has been recently demonstrated ...
How competition and cooperation between bacteria shape antibiotic resistance
New computational simulations suggest that the effects of antibiotics on a bacterial community depend on whether neighboring species have competitive or cooperative relationships, as well as their spatial arrangement. Sylvie ...
Dead plankton, stunned fish: the harms of man-made ocean noise
Human-caused ocean noise and its dangers to marine life are the focus of meetings at the United Nations this week, a victory for advocacy groups that have long warned of this problem.
Koko the gorilla, who learned sign language, dies at 46
Koko the gorilla, whose remarkable sign-language ability and motherly attachment to pet cats helped change the world's views about the intelligence of animals and their capacity for empathy, has died at 46.
Zebrafish's near 360 degree UV-vision knocks stripes off Google Street View
Tiny freshwater fish have a view of the world that blows Google Street View out of the water—using different parts of their eyes to deliver optimum uses of colour, black-and-white and ultraviolet.
Crowding inside cells may influence many functions and major diseases
Among the most studied protein machines in history, mTORC1 has long been known to sense whether a cell has enough energy to build the proteins it needs to multiply as part of growth. Because faulty versions of mTORC1 contribute ...
Scientists discover new gene expression mechanism with possible role in human disease
When cells grow and divide to ensure a biological function—such as a properly working organ—DNA must be unwound from its typical tightly packed form and copied into RNA to create proteins. When this process goes awry—if ...
