Scientists at the Stanford University School of Medicine have developed a new procedure that uses modified messenger RNA to quickly and efficiently increase the length of human telomeres, the protective caps on the ends of chromosomes that are associated with aging and disease.

Treated cells behave as if they are much younger than untreated cells, multiplying with abandon in the laboratory dish rather than stagnating… read more

A demo of the Oculus Rift device from Oculus VR. has convinced Will Greenwald of PC Magazine.that it can make first-person games immersive to an unforeseen extent.

“Oculus VR is getting ready to ship developer kits, but the Oculus Rift is a long way from hitting stores. While the technology is there, the combination of stereoscopic vision and head-tracking means games need to be built for the… read more

European regulators have approved the first therapy in the western world that can correct errors in a person’s genetic code, according to Amsterdam-based uniQure (formerly Amsterdam Molecular Therapeutics),

Europe has approved Glybera for treatment of Lipoprotein Lipase Deficiency (LPLD), a very rare, inherited disease. Patients with LPLD are unable to metabolize the fat particles carried in their blood, which leads to inflammation of the pancreas (pancreatitis).… read more

Future foods: what will we be eating in 20 years’ time?

August 6, 2012

Volatile food prices and a growing population mean we have to rethink what we eat, say food futurologists. So what might we be serving up in 20 years’ time, asks BBC News?

  • Insects will become a staple of our diet: a great source of protein, cost less to raise than cattle, consume less water and do not have much of a carbon footprint.
  • Sonic-enhanced food: certain sounds could

Genetically engineering ‘ethical’ babies is a moral obligation, says Oxford professor

August 19, 2012

Genetically screening our offspring to make them better people is just ‘responsible parenting’, claims an eminent Oxford academic, The Telegraph reports.

Professor Julian Savulescu said that creating so-called designer babies could be considered a “moral obligation” as it makes them grow up into “ethically better children”.

He said that we should actively give parents the choice to screen out personality flaws in their children… read more

ESA astronaut Samantha Cristoforetti has shot some awesome (and scary) images of super typhoon Maysak from the International Space Station.

The RapidScat instrument on the ISS saw Typhoon Maysak’s strongest winds wrapped tightly around its center, extending outward to over 30 miles from the eye.

With sustained winds at 160 mph, Maysak struck the Micronesian nation over the weekend, killing at least five people,… read more

How the Internet (and sex) amplifies irrational group behavior

New research from the University of Copenhagen combines formal philosophy, social psychology, and decision theory to understand and tackle these phenomena.

“Group behavior that encourages us to make decisions based on false beliefs has always existed.

However, with the advent of the Internet and social media, this kind of behavior is more likely to occur than ever, and on a much larger scale, with… read more

Whole-genome sequences of 17 of the world’s oldest living people published

Researchers unable to find genes significantly associated with extreme longevity
November 13, 2014

Misao Okawa, the world's oldest living person

Using 17 genomes, researchers were unable to find rare protein-altering variants significantly associated with extreme longevity, according to a study published November 12, 2014 in the open-access journal PLOS ONE by Hinco Gierman from Stanford University and colleagues.

Supercentenarians are the world’s oldest people, living beyond 110 years of age. Seventy-four are alive worldwide; 22 live in the U.S. The authors of this study performed whole-genome sequencing on 17 supercentenarians to… read more

How to store solar energy more cost-effectively for use at night

There’s currently no cost-effective, large-scale way to store solar energy, but Stanford researchers have developed a solution: using electrolysis to turn tanks of water and hydrogen into batteries. During the day, electricity from solar cells could be used to break apart water into hydrogen and oxygen. Recombining these gases would generate electricity for use at night.

There’s one major problem. Electrolysis uses electricity to crack the chemical bonds that… read more

Real-world stereotypes continue to exist in virtual worlds

Stereotypes related to gender and appearance that burden women in the real world could follow them into virtual ones, according to Penn State researchers.

In a study of how people interacted with avatars in an online game, women received less help from fellow players than men when they operated an unattractive avatar and when they used a male avatar, said T. Franklin Waddell, a doctoral candidate in massread more

Autonomous taxis could be cheaper and improve the environment, says Berkeley Lab study

Self-driving car concept (credit: Google)

It’s the year 2030. A fleet of driverless taxis roams throughout your city, ready to pick you up and take you to your destination at a moment’s notice. As a result, greenhouse gases are now 63 to 82 percent lower than with a privately owned hybrid car and 90 percent lower than a 2014 gasoline-powered private vehicle. …

Those numbers are from a new study from Lawrence Berkeley National Laboratory… read more

Limb regeneration: do salamanders hold the key?

June 24, 2014

Salamander (credit: UCL)

The secret of how salamanders successfully regrow body parts is being unravelled by University College London (UCL) researchers in a bid to apply it to humans.

For the first time, researchers have found that the “ERK pathway” must be constantly active for salamander cells to be reprogrammed, and hence able to contribute to the regeneration of different body parts.

The team identified a key… read more

As part of an update to the national fingerprint database, the FBI has begun rolling out facial recognition to identify criminals, New Scientist reports.

It will form part of the bureau’s long-awaited, $1 billion Next Generation Identification (NGI) program, which will also add biometrics such as iris scans, DNA analysis, and voice identification to the toolkit. A handful of states began uploading their photos as… read more

Moore’s Law threatened by lithography woes

Moore’s Law is losing steam due to delayed introduction of next-generation extreme ultraviolet lithography (EUV), said experts at the 2012 International Symposium on Extreme Ultraviolet Lithography, EE Times reports.

EUV systems need light sources that are nearly 20 times more powerful than the ones used today to lay down patterns on next-generation chips that target sizes as small as 14 nm. Lithography experts said that… read more

This Is how Dennis Tito plans to send people to Mars

Mars-Capsule_220213.m

If Dennis Tito has his way, two people will leave our planet in January 2018 and make a trip to Mars and back, with a quick flyby, SpaceRef reports.

The project is being spearheaded by a non-profit organization, the Inspiration Mars Foundation.

Tito’s mission will be facilitated by donors, not investors.

Tito and a group of coauthors from NASA and several aerospace companies… read more
