Rockefeller University have discovered tantalizing clues about the origins of our ability to understand what other people are thinking

Posted on May 19, 2017 by adminedit

Working with rhesus monkeys, researchers have identified a brain network dedicated to processing social interaction. Scientists call our ability to understand another person’s thoughts—to intuit their desires, read their intentions, and predict their behavior—theory of mind. It’s an essential human trait, one that is crucial to effective social interaction. But where did it come from? Working with rhesus macaque monkeys, researchers in Winrich Freiwald’s Laboratory of Neural Systems ...

Messerli Research Institute in Vienna research suggest Dogs are as smart as humans

Posted on April 9, 2017 by adminedit

Human communication is unique because it strongly relies on language as well as on the exceptional motivation of humans to share information with others. Identifying by means of words what someone is talking about is hardly available for non-human animals, but human as well as non-human animals can use the direction of others’ gaze and gestures to detect to which object or social partner others’ behaviour is referring to. https://youtu.be/crL6mn_LW28 Hence, following others’ gaze and g...

NYU research suggest brain size in primates can be predicted by diet.

Posted on March 28, 2017 by adminedit

Brain size in primates is predicted by diet, an analysis by a team of New York University anthropologists indicates. These results call into question “the social brain hypothesis,” which has posited that humans and other primates are big-brained due to factors pertaining to sociality. The findings, which appear in the journal Nature Ecology and Evolution, reinforce the notion that both human and non-human primate brain evolution may be driven by differences in feeding rather than in socializa...

Electronic sensors that monitor temperature and pressure within the skull

Posted on May 3, 2016 by adminedit

Researchers have developed a new class of small, thin electronic sensors that monitor temperature and pressure within the skull – crucial health parameters after a brain injury or surgery – then melt away when no longer needed. This eliminates the need for additional surgery to remove the monitors and reduces the risk of infection and haemorrhage. Similar sensors can be adapted for postoperative monitoring in other body systems as well, the researchers say. Led by John A. Rogers, a professor ...

River pollution causes gender-bending in fish

Smart Mice with half Human brain

Posted on November 3, 2015November 3, 2015 by smerchantny@gmail.com

Smart Mice with half Human brain Mice have been created whose brains are half human. As a result, the animals are smarter than their siblings by professors at the University of Rochester Medical Center in New York. The idea is not to mimic fiction, but to advance our understanding of human brain diseases by studying them in whole mouse brains rather than in dishes. The altered mice still have mouse neurons – the “thinking” cells that make up around half of all their brain cells. But pra...

GMO – Genetically Modified Organisms

Designer Babies Genetically modified babies have DNA from three different adults. Although having DNA from more than two sources can occur naturally (as in the cases of microchimerism and tetragametic chimerism), these 15 babies were created with a method called “cytoplasmic transfer,” which had been banned by the FDA. The method was initially developed to save female eggs that had been difficult to fertilize and was showing much promise—until tracking the growth of the genetically modified b...
