A laboratory in Lanarkshire has started harvesting stem cells from children’s teeth.

It’s hoped the cells can be used in a cure if the children develop a disease later in life.

The American company BioEden will cryogenically store the cells in return for a monthly fee.

Relatively few stem cell therapies are currently in use but hundreds more are being researched.

We took the technology out of the studio and into a car – making Holoportation truly mobile. To accomplish this, we reduced the bandwidth requirements by 97%, while still maintaining quality. This new mobile Holoportation system greatly increases the potential applications of real-time 3D capture and transmission.

Scientists have managed to coax living cells into making carbon-silicon bonds, demonstrating for the first time that nature can incorporate silicon — one of the most abundant elements on Earth — into the building blocks of life.

While chemists have achieved carbon-silicon bonds before — they’re found in everything from paints and semiconductors to computer and TV screens — they’ve so far never been found in nature, and these new cells could help us understand more about the possibility of silicon-based life elsewhere in the Universe.

After oxygen, silicon is the second most abundant element in Earth’s crust, and yet it has nothing to do with biological life.

DARPA is developing robotic support and maintenance of geosynchronous Earth orbit satellites with the Phoenix and GEO programs

The traditional process of designing, developing, building and deploying space systems is long, expensive and complex. These difficulties apply especially to the increasing number of expensive, mission-critical satellites launched every year into geosynchronous Earth orbit (GEO), approximately 22,000 miles above the Earth. Unlike objects in low Earth orbit (LEO), such as the Hubble Space Telescope, satellites in GEO are essentially unreachable with current technology.

DARPA’s Phoenix program seeks to change this paradigm and reduce the cost of space-based systems by developing and demonstrating new satellite assembly architectures and delivery systems. Phoenix is currently focusing on two primary technical areas of research:

It’s supposed to be the most fundamental constant in physics, but the speed of light may not always have been the same. This twist on a controversial idea could overturn our standard cosmological wisdom.

In 1998, Joao Magueijo at Imperial College London, proposed that the speed of light might vary, to solve what cosmologists call the horizon problem. This says that the universe reached a uniform temperature long before heat-carrying photons, which travel at the speed of light, had time to reach all corners of the universe.
