CNIO researchers obtain the first mice born with hyper-long telomeres and show that it is possible to extend life without any genetic modification

Posted by in categories: biotech/medical, genetics, life extension

A chance finding ten years ago led to the creation by researchers of the Spanish National Cancer Research Centre (CNIO) of the first mice born with much longer telomeres than normal in their species. Given the relationship between telomeres and ageing – telomeres shorten throughout life, so older organisms have shorter telomeres -, scientists launched a study generating mice in which 100% of their cells had hyper-long telomeres. The findings are published in Nature Communications and show only positive consequences: the animals with hyper-long live longer in better health, free from cancer and obesity. The most relevant thing for the authors is the fact that longevity has been significantly increased for the first time ever without any genetic modification.

“This finding supports the idea that, when it comes to determining longevity, genes are not the only thing to consider”, indicates Maria Blasco, Head of the CNIO Telomeres and Telomerase Group and intellectual author of the paper. “There is margin for extending life without altering the genes”.

Telomeres form the end of chromosomes, in the nucleus of each cell in the body. Their function is to protect the integrity of the genetic information in DNA. Whenever the cells divide the telomeres, they are shortened a little, so one of the main characteristics of ageing is the accumulation of short telomeres in cells. “Telomere shortening is considered to be one of the primary causes of ageing, given that short telomeres cause ageing of the organism and reduce longevity”, as the paper published in Nature Communications explains.

Scientists Create Solid Light

Posted by in category: futurism

Circa 2014 o.o

On a late summer afternoon it can seem like sunlight has turned to honey, but could liquid—or even solid—light be more than a piece of poetry? Princeton University electrical engineers say not only is it possible, they’ve already made it happen.

In Physical Review X, the researchers reveal that they have locked individual photons together so that they become like a solid object.

Faster, More Secure Communications Using Structured Light in Quantum Protocols

Posted by in categories: quantum physics, security

Structured light is a fancy way to describe patterns or pictures of light, but deservedly so as it promises future communications that will be both faster and more secure.

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. In AVS Quantum Science, from AIP Publishing, researchers from the University of Witwatersrand in South Africa review the progress being made in using structured light in quantum protocols to create a larger encoding alphabet, stronger security and better resistance to noise.

“What we really want is to do quantum mechanics with patterns of light,” said author Andrew Forbes. “By this, we mean that light comes in a variety of patterns that can be made unique — like our faces.”

Researchers transmit energy with laser in ‘historic’ power-beaming demonstration

Posted by in categories: energy, military

It was the second day of a three-day-long tech demonstration at the David Taylor Model Basin at the Naval Surface Warfare Center in Bethesda, Maryland, where attendees had gathered to stand around in the dark to look at something they mostly couldn’t see.

It was a long-range, free-space power beaming system — the first of its kind. Attendees that day, May 23, could see the system itself—the two 13-foot-high towers, one a 2-kilowatt laser transmitter, the other a receiver of specially designed photovoltaics. But the important part, the laser that was beaming 400 watts of power across 325 meters, from the transmitter to the receiver, was invisible to the naked eye.
