Light has been shed on the dark parts of the Moon with experiments by University of Edinburgh researchers simulating billions of years of lunar evolution.

It is generally believed the Moon was created after an early, semi molten, Earth collided with a planet the size of Mars.

The collision was so great that the orbiting debris would have formed a so-called lunar magma ocean, or liquefied rock, up to several hundred kilometres deep that would have covered the Moon's surface.

Yet until now, it has remained a mystery as to how this magma ocean cooled and how the lunar landscape evolved into white highlands and dark valleys.

This week, for the first time in humans, a heart failure patient received adult stem cells – taken from his own adipose (fat) tissue – which were processed and injected directly into the heart muscle with a special catheter. Francisco Fernandez-Avilés, M.D. performed the procedure in Madrid. The Texas Heart Institute at St. Luke’s Episcopal Hospital is leading the collaborative clinical trial which will involve 30 patients.

The trial site for the study is Hospital General Universitario Gregorio Marañón in Madrid, Spain. Dr. Fernandez-Avilés, Professor of Cardiovascular Medicine and Chief of Cardiology Service at Gregorio Marañón and Dr.

Researchers at the University of Illinois at Urbana-Champaign have developed a novel computational image-forming technique for optical microscopy that can produce crisp, three-dimensional images from blurry, out-of-focus data.

Called Interferometric Synthetic Aperture Microscopy, ISAM can do for optical microscopy what magnetic resonance imaging did for nuclear magnetic resonance, and what computed tomography did for X-ray imaging, the scientists say.

Video games that contain high levels of action, such as Unreal Tournament, can actually improve your vision.

Researchers at the University of Rochester have shown that people who played action video games for a few hours a day over the course of a month improved by about 20 percent in their ability to identify letters presented in clutter—a visual acuity test similar to ones used in regular ophthalmology clinics.

In essence, playing video game improves your bottom line on a standard eye chart.

A giant elliptical galaxy seen in an image from the Hubble Space Telescope is the closest gravitational lens yet known, according to information released by the Hubble Heritage Project Tuesday (Feb. 6).

John Blakeslee, an assistant professor with the Department of Physics and Astronomy at Washington State University, working with colleagues from the University of Hawaii and the University of Durham in England, targeted the galaxy for a closer look by Hubble.

A greenhouse gas that has become the bane of modern society may have saved Earth from completely freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks.

Scientists have for years theorized that high concentrations of greenhouse gases could have helped Earth avoid global freezing in its youth by allowing the atmosphere to retain more heat than it lost.

In January, I spent two weeks attending the world’s largest consumer technology convention and a much smaller but very important annual television convention.  This column is to give you an idea of what will new cutting edge gadgets will soon be available and to also suggest ways they will affect how you consume media and access information.

Many human proteins are not as good as they might be because the gene sequences that code for them have a double role which slows down the rate at which they evolve, according to new research published in PLoS Biology.

By tweaking these dual role regions, scientists could develop gene therapy techniques that produce proteins that are even better than those found in nature, and could one day be used to help people recover from genetic disorders.

The stretch of DNA which codes for a specific protein is often interrupted by sections of apparently useless DNA – known as introns – which need to be edited out in order to produce a new protein.

Wouldn't it be great if we could get computer chips to grow on trees? Or at least use the specific bonds of DNA molecules to get nanostructures to grow themselves right in the test tube? This technology could be used to build everything from tiny electronics components to machines that sequence DNA. This is shown in a dissertation from Mid Sweden University.

Building structures as tiny as a few nanometers is a major problem with today's technology. This is an important hurdle, because really tiny things can be extremely useful.
