Gut bacteria often similar in humans and chimps, study finds
(HealthDay)—Humans and chimpanzees have much in common, biologically speaking, and that may now include certain communities—or ecosystems—of gut bacteria, a new study finds.
Brain study: Singing mice show signs of learning
Guys who imitate Luciano Pavarotti or Justin Bieber to get the girls aren't alone. Male mice may do a similar trick, matching the pitch of other males' ultrasonic serenades. The mice also have certain brain ...
Li-Fi: Edinburgh prof seeds LEDs for communication
Trifunctional molecule decodes cellular communication
(Phys.org)—How does one define the factors on the surface of human cells to which a molecule of interest binds? This question is typically hard to answer. Researchers of ETH Zurich have developed a new ...
First mammalian 'cell phone'
(Phys.org)—Researchers from ETH Zurich have quite literally created a "cell phone": they have reprogrammed mammalian cells in such a way that they can "phone" each other via chemical signals.
Ants have an exceptionally 'hi-def' sense of smell
The first complete map of the ants' olfactory system has discovered that the eusocial insects have four to fives more odorant receptors—the special proteins that detect different odors—than other insects.
Study: Bacteria on marine sponges can develop capacity to move and inhibit biofilm formation
(Phys.org)—A new study shows that when enough bacteria get together in one place, they can make a collective decision to grow an appendage and swim away. This type of behavior has been seen for the first time in marine ...
Home wifi could be used for emergency responders
Wireless routers for homes and offices could be knitted together to provide a communications system for emergency responders if the mobile phone network fails, German scientists reported on Monday.
Maths experts question key ecological theory
Mathematicians at the University of York in the UK and the University of Canterbury in New Zealand say they have disproved a widely accepted theory underpinning the operation of complex networks of interactions in the natural ...
Russian whizzes win global collegiate IT contest
Three Russian computer whizzes were crowned the world's top collegiate programmers Thursday, when they clobbered 111 other teams from across the globe to win the 36th annual "Battle of Brains" in Warsaw.
Several antennas in one: A major innovation for mobile communications
(Phys.org) -- Scientists at EPFL have developed a single antenna that is capable of transmitting the same data as a two-antenna system. This achievement will be more than useful for future communication systems.
Protein analysis investigates marine worm community
(Phys.org) -- Techniques used by researchers from the Department of Energy's Oak Ridge National Laboratory to analyze a simple marine worm and its resident bacteria could accelerate efforts to understand more ...
Protest targets US cyber intelligence legislation
Civil liberties groups on Monday launched protests targeting proposed US cyber intelligence law that they fear would let police freely dip into people's private online information.
Baboons, infants show similar gesturing behavior, suggesting shared communication systems
Both human infants and baboons have a stronger preference for using their right hand to gesture than for a simple grasping task, supporting the hypothesis that language development, which is lateralized in the left part of ...
