These proteins can transfer electrons making this micro-organism potentially rather interesting as an electricity-generating system. The research could allow researchers to tether bacteria directly to electrodes creating efficient microbial fuel cells or bio-batteries powered by human or animal waste. Such an advance could also hasten the development of system based on microbial agents that can clean up oil spills or provide a new approach to remediating radioactive waste.

Consensus thinking in the peer-review literature is that the parts of one’s brain responsible for physical pain, the dorsal anterior cingulate and anterior insula, also underlie emotional pain. Researchers at Columbia University in New York recruited 40 people who’d recently ended a romantic relationship, put them in a functional magnetic resonance imaging machine, and recorded their reactions to physical and then emotional pain. Physical pain was created by heating the person’s left forearm, compared to having the arm merely warmed. Emotional pain was created by looking at pictures of the former partner and remembering the breakup, compared to when looking at a photo o...

The discovery could take us a step closer to magnetic memory devices with capacities thousands of times denser than current high-end hard drives. Clouds from both sides – Atmospheric and climate models may have overlooked the fact that exactly how clouds appear to reduce the amount of sunlight available for warming the surface of the earth depends on the wavelength being measured across the spectrum from infrared to ultraviolet. The finding could now help researchers improve climate models by factoring in the effects of cloud cover more precisely.

It is not clear yet how to assess who will benefit the most from training and the cognitive tests used in the past were not very good at predicting this.   Dr. Kramer and his colleagues recently showed that the brain activity in a specific part of the brain (the dorsal striatum) at the start of training in a complex video-game could accurately predict how well people will benefit from the training.  Thirty-four young adults with little experience in playing video games were trained to play a complex video game called Space Fortress. After initial instruction, they played the game while their brains were being scanned using fMRI. For the next three to eight weeks (38 days on average) they completed ten two-...

M. (2010). The Appeal of the Brain in the Popular Press. Perspectives on Psychological Science, 5(6), 762-766.Since the advent of human neuroimaging, and of functional magnetic resonance imaging (fMRI) in particular, the popular press has shown an increasing interest in brain-related findings. In this article, I explore possible reasons behind this interest, including recent data suggesting that people find brain images and neuroscience language more convincing than results that make no reference to the brain (McCabe & Castel, 2008; Weisberg, Keil, Goodstein, Rawson, & Gray, 2008). I suggest that part of the allure of these data are the deceptively simply messages they afford, as well as general, but sometimes misguided, confidence in biological data. In addition to cataloging som...

The method uses functional MRI (fMRI) and diffusion tensor magnetic resonance imaging (DTI) to scan the brain, and data crunching software to interpret the data. The researchers hope that the finding will help parents and therapists uniquely identify which learning tools are best for each child. From the announcement by Vanderbilt University : The 45 children who took part in the study ranged in age from 11 to 14 years old. Each child first took a battery of tests to determine their reading abilities. Based on these tests, the researchers classified 25 children as having dyslexia, which means that they exhibited significant difficulty le...

Acetone can be a sign that someone suffers from diabetes, so in theory this machine could use scent to diagnose this disease. That story brought to mind other stories I’ve heard about people using dogs to sniff out cancer in people. According to this article: “The results of the study showed that dogs can detect breast and lung cancer with sensitivity and specificity between 88% and 97%. The high accuracy persisted even after results were adjusted to take into account whether the lung cancer patients were currently smokers. Moreover, the study also confirmed that the trained dogs could even detect the early stages of lung ...
