Two antibodies are better than one for preventing HIV infection

Wed, 20 Sep 17 00:12:00 -0700

A cocktail of two broadly-neutralizing HIV-1 antibodies (bNAbs) protected primates against infection with a mixed population of HIV viruses -- conditions that mimic real-world transmission -- researchers report.



Welfare of zoo animals set to improve

Mon, 18 Sep 17 00:03:00 -0700

The wellbeing of zoological animals is set to improve following the successful trial of a new welfare assessment grid, a new study in the journal Veterinary Record reports.



Looking stressed can help keep the peace

Mon, 11 Sep 17 00:05:20 -0700

This is the first research to suggest scratching may have evolved as a communication tool to help social cohesion.



Why your ancestors would have aced the long jump

Mon, 11 Sep 17 00:07:00 -0700

A 52-million-year-old ankle fossil suggests our prehuman ancestors were high-flying acrobats. For years, scientists thought the ancestors of today's humans, monkeys, lemurs and apes were relatively slow and deliberate animals, using their grasping hands and feet to creep along small twigs and branches. But a new study suggests the first primates were masters at leaping through the trees.



Monkey sees ... monkey knows?

Wed, 06 Sep 17 00:16:10 -0700

Monkeys had higher confidence in their ability to remember an image when the visual contrast was high. These kinds of metacognitive illusions -- false beliefs about how we learn or remember best -- are shared by humans, leading brain and cognitive scientists to believe that metacognition could have an evolutionary basis.



The sniff test of self-recognition confirmed: Dogs have self-awareness

Tue, 05 Sep 17 00:05:10 -0700

A new research carried out by the Department of Psychology of the Barnard College in the USA, in publication on the journal Behavioural Processes, used a sniff-test to evaluate the ability of dogs to recognize themselves. The experiment confirms the hypothesis of dogs' self-cognition proposed last year by Professor Roberto Cazzolla Gatti of the Biological Institute of the Tomsk State University, Russia.



Researchers develop Lassa fever treatment effective eight days after infection

Tue, 05 Sep 17 00:00:10 -0700

A collaborative team of scientists, led by a group at The University of Texas Medical Branch at Galveston, have successfully protected nonhuman primates against one of the most deadly viruses in the world, Lassa fever, eight days after they became infected. The findings are now available in Nature Medicine.



Face value

Mon, 04 Sep 17 00:11:00 -0700

Scientists have long deemed the ability to recognize faces innate for people and other primates -- something our brains just know how to do immediately from birth. However, the findings of a new Harvard Medical School study published Sept. 4 in the journal Nature Neuroscience cast doubt on this longstanding view.



Blame it on the bossa nova: How music changes our perception of touch

Mon, 04 Sep 17 00:14:20 -0700

Music touches. Until recently, this was only meant in a figurative way -- now it can also be taken literally. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences have found that touch is perceived differently, depending on the music being played. The sexier we perceive the music we are listening to, the more sensual we experience the contact if we think we are touched by another person.



Use of brain-computer interface, virtual avatar could help people with gait disabilities

Wed, 23 Aug 17 00:03:50 -0700

Researchers from the University of Houston have shown for the first time that the use of a brain-computer interface augmented with a virtual walking avatar can control gait, suggesting the protocol may help patients recover the ability to walk after stroke, some spinal cord injuries and certain other gait disabilities.



Giving cancer-killing viruses a boost

Wed, 23 Aug 17 00:08:30 -0700

Scientists have found a compound that helped a tumor-targeting virus kill liver cancer more effectively while sparing healthy cells, which could someday translate to a viable treatment approach in humans.
