| Assessing others: Evaluating expertise of humans, computer algorithms Posted: 16 Jan 2014 08:35 AM PST Researchers used fMRI technology to monitor the brain activity of volunteers as they interacted with "experts" -- some human, others computer algorithms -- to predict the behavior of a hypothetical financial asset. Volunteers responded more positively to human rather than computer "experts." |
| Posted: 16 Jan 2014 08:35 AM PST The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain? |
| The way to a chimpanzee's heart is through its stomach Posted: 16 Jan 2014 08:35 AM PST Researchers measured the urinary oxytocin levels in wild chimpanzees after food sharing and found them to be elevated in both donor and receiver compared to social feeding events without sharing. Furthermore, oxytocin levels were higher after food sharing than after grooming, another cooperative behavior, suggesting that food sharing might play a more important role in promoting social bonding. |
| Smart object recognition algorithm doesn't need humans Posted: 16 Jan 2014 06:11 AM PST If we've learned anything from post-apocalyptic movies it's that computers eventually become self-aware and try to eliminate humans. One engineer isn't interested in that development, but he has managed to eliminate the need for humans in the field of object recognition by creating an algorithm that can accurately identify objects in images or video sequences without human calibration. |
| Posted: 16 Jan 2014 05:51 AM PST A review and update of a controversial 20-year-old theory of consciousness claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in "microtubules" inside brain neurons corroborates this theory, according to review authors. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions. |
| Stem cells overcome damage in other cells by exporting mitochondria Posted: 16 Jan 2014 05:50 AM PST A research team has identified a protein that increases the transfer of mitochondria from mesenchymal stem cells to lung cells. The researchers reveal that the delivery of mitochondria to human lung cells can rejuvenate damaged cells. The migration of mitochondria from stem cells to epithelial cells also helps to repair tissue damage and inflammation linked to asthma-like symptoms in mice. |
| When doctor's visit is a guilt trip Posted: 15 Jan 2014 02:29 PM PST Some patients react to a shaming encounter with a health provider in a way that promotes health while others turn to lying or avoidance. Why? What makes the difference? |
| Hugging hemes help electrons hop Posted: 15 Jan 2014 02:26 PM PST Researchers simulating how certain bacteria run electrical current through tiny molecular wires have discovered a secret nature uses for electron travel. This is the first time scientists have seen this evolutionary design principle for electron transport, |
| Theory behind popular blood-type diet debunked Posted: 15 Jan 2014 02:22 PM PST Researchers have found that the theory behind the popular blood type diet -- which claims an individual's nutritional needs vary by blood type -- is not valid. |
