UCLA Researchers have exploited a recently-discovered mammalian system for the mitochondrial import of nuclear-encoded RNA to import, express, and demonstrate functional protein translation from engineered mRNA and tRNA constructs. They used this system, with modifications for mitochondrial targeting and orthotopic translation, to rescue respiration in human mitochondriopathy cells. While further characterization and extension is clearly needed, this approach appears offer great promise for the correction of age-related mitochondrial DNA mutations.

A Siberian woolly mammoth preserved in permafrost could walk the Earth again after 10,000 years, after Russian academics signed a deal with a controversial Korean scientist to clone the animal.
Hwang Woo-Suk of South Korea's Sooam Biotech Research Foundation -- who created the world’s first cloned dog, Snuppy, in 2005 -- will implant the nucleus from a mammoth cell into an elephant egg to create a mammoth embryo.
The embryo will then be implanted into an elephant’s womb. The Koreans say research could begin this year.
Despite a century of research, memory encoding in the brain has remained mysterious. Neuronal synaptic connection strengths are involved, but synaptic components are short-lived while memories last lifetimes.
(Video) "Whether you are part of a family, organizational team or business in a supply chain, systems thinking is a valuable approach to understanding the complexity of today's world. Peter Senge, author of The Fifth Discipline, Senior lecturer at MIT and Founder of the Society for Organizational Learning shares his perspectives on leadership and systems thinking with IBM. Senge focuses on the problems that are most difficult to solve and the mental models today's leaders need in order to build a smarter planet. Leaders today need to be able to be prepared reassess their strategies, work across multiple groups to find solutions and have the vision to work through high leverage solutions over time. Working smarter means working in ways that are collective and are based on collective intelligence across cities and supply chains to produce social, ecological and economic well being."
Synthetic biology needs more oversight, and the government needs to put in place regulations specific for this field. That is the bottom line for 111 environmental, watchdog, and other organizations that released a report today with specific recommendations for managing new biological techniques for building and remaking organisms for research and commercial uses ranging from medicines to biofuels.
Biotechnology |In June 2011, an Eritrean man entered an operating theatre with a cancer-ridden windpipe, but left with a brand new one. People had received windpipe transplants before, but Andemariam Teklesenbet Beyene’s was different. His was the first organ of its kind to be completely grown in a lab using the patient’s own cells.
Beyene’s windpipe is one of the latest successes in the ongoing quest to grow artificial organs in a lab. The goal is deceptively simple: build bespoke organs for individual patients by sculpting them from living flesh on demand. No-one will have to wait on lengthy transplant lists for donor organs and no-one will have to take powerful and debilitating drugs to prevent their immune systems from rejecting new body parts.
(PhysOrg.com) -- With the aim to make it easier to launch spacecraft into low Earth orbit (LEO), two researchers have turned to maglev technology to catapult a payload hundreds of miles above the Earth.

IT IS not every day that a piece of science fiction takes a step closer to nuts-and-bolts reality. But that is what seems to be happening to wormholes. Enter one of these tunnels through space-time, and a few short steps later you may emerge near Pluto or even in the Andromeda galaxy millions of light years away.
You probably won't be surprised to learn that no one has yet come close to constructing such a wormhole. One reason is that they are notoriously unstable. Even on paper, they have a tendency to snap shut in the blink of an eye unless they are propped open by an exotic form of matter with negative energy, whose existence is itself in doubt.
Now, all that has changed. A team of physicists from Germany and Greece has shown that building wormholes may be possible without any input from negative energy at all. "You don't even need normal matter with positive energy," says Burkhard Kleihaus of the University of Oldenburg in Germany. "Wormholes can be propped open with nothing."
