Scientists at the McEwen Centre for Regenerative Medicine and the Ontario Cancer Institute have isolated a human blood stem cell in its purest form: as a single stem cell capable of regenerating the entire blood system. "This discovery means we now have an increasingly detailed road map of the human blood development system, including the much sought after stem cell," says principal investigator John Dick, who holds a Canada Research Chair in Stem Cell Biology and is a Senior Scientist at the McEwen Centre for Regenerative Medicine and the Ontario Cancer Institute, University Health Network (UHN). "We have isolated a single cell that makes all arms of the blood system, which is key to maximizing the potential power of stem cells for use in more clinical applications. Stem cells are so rare that this is a little like finding a needle in a haystack," says Dr. Dick. Ref.: John E.

Theodore Berger and his team at the USC Viterbi School of Engineering's Department of Biomedical Engineering have developed a neural prosthesis for rats that is able to restore their ability to form long-term memories after they had been pharmacologically blocked. In a dramatic demonstration, Berger blocked the ability to rats to form long-term memories by using pharmacological agents to disrupt the neural circuitry that communicates between two subregions of the hippocampus, CA1 and CA3, which interact to create long-term memory, prior research has shown. The rats were unable to remember which lever to pull to gain a reward, or could only remember for 5-10 seconds, when previously they could remember for a long period of time. The researchers then developed an artificial hippocampal system that could duplicate the pattern of interaction between CA3-CA1 interactions. Long-term memory capability returned to the pharmacologically blocked rats when the team activated the electronic device programmed to duplicate the memory-encoding function. The researchers went on to show that if a prosthetic device and its associated electrodes were implanted in animals with a normal, functioning hippocampus, the device could actually strengthen the memory being generated internally in the brain and enhance the memory capability of normal rats. "These integrated experimental modeling studies show for the first time that with sufficient information about the neural coding of memories, a neural prosthesis capable of real-time identification and manipulation of the encoding process can restore and even enhance cognitive mnemonic processes," says the paper. Next steps, according to Berger and Deadwyler, will be attempts to duplicate the rat results in primates (monkeys), with the aim of eventually creating prostheses that might help human victims of Alzheimer's disease, stroke, or injury recover function.

Educational researchers at the Technical University of Munich (TUM) have found that schoolchildren can independently develop strategies for solving complex mathematical tasks, with weaker students proving just as capable as their stronger classmates. Researchers in mathematics education worked with approximately 1600 8th grade high-school students in various German states. Following an introduction to the general topic by their teachers, the school children were given a workbook of geometric tasks that they had to solve on paper and using a computer over four school periods. Calculating the surface area of Gran Canaria was one of the real-world, free-form assignments the students had to tackle. The workbook material included explanations and examples of various problem-solving approaches. The teachers took a back seat during the session but were on hand to answer questions from the children, who worked in pairs. After testing the students' skills before and after the session, the researchers recorded a significant improvement in their capabilities. The students learned to apply mathematics more effectively, the researchers said. The students were also able to call on these skills in a further test three months later. "We expected students who were weaker at math to benefit more from a greater degree of guidance through the module," said professor Kristina Reiss.  "But we didn't see a significant difference between these and stronger students." The researchers also found that there were also no differences between boys and girls. "We now know that students - also those who are weaker in math - have the skills to master even very complex subject matters at their own pace," said Reiss. Topics: Cognitive Science/Neuroscience

"Similarly, how should cancer biologists think about cancer cells capable of producing vascular endothelial growth factor, a protein that promotes the growth of blood vessels? Clearly, the importance of this protein only makes sense when thinking about a cancer cell's environment: how close it is to blood vessels that it can exploit, for example."

Transhumanists support the ethical application of technologies to augment human capabilities and lifespans.

"The press had a tendency to consistently overestimate [biohackers'] capabilities and underestimate our ethics. We have personal computing, why not personal biotech? That's the question biologist Ellen Jorgensen and her colleagues asked themselves before opening Genspace, a nonprofit DIYbio lab in Brooklyn devoted to citizen science, where amateurs can go and tinker with biotechnology. Far from being a sinister Frankenstein's lab (as some imagined it), Genspace offers a long list of fun, creative and practical uses for DIYbio. Ellen Jorgensen is at the leading edge of the do-it-yourself biotechnology movement, which brings scientific exploration and understanding to the masses"

"t turns out that all over the world there were people trying to do similar things - opening biohacker spaces. Three years later, this is a thriving global community. Each lab has a flavor of where it was created - people work together or alone, in big cities or small villages, they build things and take them apart, and do much, much more. The spirit is open. But what about the dark side? What about biosafety, biosecurity? The minute Genspace opened their doors, journalists called. And the only question they wanted to ask was, "Would this lab create the next Frankenstein?" The press was overestimating their capabilities - and underestimating their ethic"

"The ArticuLab's mission is to study human interaction in social and cultural contexts as the input into computational systems that in turn help us to better understand human interaction, and to improve and support human capabilities in areas that really matter."

"We were determined to build one singular AI. This means Remi is capable of handling complex requests easily. Things like 'Can you get me a taxi to my meeting with John Smith and find me a good coffee on the way' are simple for Remi."

University of Michigan researchers George Mashour, M.D., Ph.D., and Jimo Borjigin, Ph.D., provide the first scientific framework for near-death experiences. "The "near-death experience" reported by cardiac arrest survivors worldwide may be grounded in science, according to research at the University of Michigan Health System. Whether and how the dying brain is capable of generating conscious activity has been vigorously debated"

Using super-high pressures similar to those found deep in the Earth or on a giant planet, Washington State University researchers have created a compact, never-before-seen material capable of storing vast amounts of energy.

Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an electrical link to living cells engineered to shuttle electrons across a cell's membrane to an external acceptor along a well-defined path. This direct channel could yield cells that can read and respond to electronic signals, electronics capable of self-replication and repair, or efficiently transfer sunlight into electricity.
