Supplement added to a standard diet improves health and prolongs life in mice

March 5, 2014

Representative photographs from blinded histopathological analysis of kidney, liver, and lung panels for mice on standard diet (SD) and SRT1720 supplementation

Activating a protein called sirtuin 1 extends lifespan, delays the onset of age-related metabolic diseases, and improves general health in mice. The findings, which appear online February 27 in the Cell Press journal Cell Reports, point to a potentially promising strategy for improving health and longevity.

Sirtuin 1, or SIRT1, is known to play an important role in maintaining metabolic balance in multiple tissues, and studies in… read more

New one-dimensional form of carbon may be the strongest material ever

Carbyne nanorods may have uses in electronics and for energy storage
October 11, 2013

Rice University researchers have determined from first-principle calculations that carbyne would be the strongest material yet discovered. The carbon-atom chains would be difficult to make but would be twice as strong as two-dimensional graphene sheets. (Credit: Vasilii Artyukhov/Rice University)

Rice U. theorists calculate atom-thick carbyne chains may be the strongest material ever, if and when anyone can make it in bulk.

Carbyne is a chain of carbon atoms held together by either double or alternating single and triple atomic bonds. That makes it a true one-dimensional material, unlike atom-thin sheets of graphene, which have a top and a bottom, or hollow nanotubes, which … read more

Elon Musk has released a video demonstrating SpaceX’s new custom 3D design interface, inspired by Iron Man.

It includes use of Leap Motion control, free-standing glass projections (from Iron Man), 3D projections using glasses, and the Occulus Rift VR headset.

After generating and manipulating the 3D model, Musk then 3D-prints an actual titanium metallic rocket-engine part from the model.

“It’s not humanly possible to practice the best possible medicine. We need machines,” said Herbert Chase, a professor of clinical medicine at Columbia University and member of IBM’s Watson Healthcare Advisory Board, Wired Science reports.

“A machine like [IBM's Watson], with massively parallel processing, is like 500,000 of me sitting at Google and Pubmed, trying to find the right information.”

Yet though Watson is clearly a powerful tool,… read more

Human v 2.0: Ray Kurzweil vs. Hugo de Garis

October 24, 2006

“Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v2.0.

“It’s predicted that by 2029 computer intelligence will equal the power of the human brain. Some believe this will revolutionise humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to… read more

Amazon is developing smartphone with 3D screen

May 10, 2013

Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new… read more

Warrior Web to augment soldiers’ endurance

DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.

DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more

Growing human organs inside pigs in Japan

Meiji University professor Hiroshi Nagashima is creating chimeric pigs, which carry genetic material from two different species, BBC News reports. It starts off by making what Nagashima calls “a-pancreatic” embryos. Inside the white pig embryo, the gene that carries the instructions for developing the animal’s pancreas has been “switched off.”

The Japanese team then introduces stem cells from a black pig into the embryo. What they have… read more

The Red Queen was right: life must continually evolve to avoid extinction

June 22, 2013

Alice_&_Red_Queen

A University of California, Berkeley study has found that a lack of new emerging species contributes to extinction over a period of millions of years.

The researchers studied 19 groups of mammals that either are extinct or in decline from a past peak in diversity, as in the case of horses, elephants, rhinos and others.

The “Red Queen” hypothesis

The study was conducted… read more

Dubai Holding plans to build the world’s largest domed city: Mall of the World, in Dubai. The temperature-controlled city (also a first) will occupy a total area of 48 million square feet — the largest indoor theme park in the world. It will be covered by a glass dome that will be open during the winter months.

The project will also house the largest shopping mall in the world,… read more

Fullerene C60 administration doubles rat lifespan with no toxicity

Researchers at the University of Paris and colleagues fed the molecule fullerene (C60 or “buckyballs”) dissolved in olive oil to rats and found it almost doubles their lifespan, with no chronic toxicity.

The results suggest that the effect of C60, an antioxidant, on lifespan is mainly due to the attenuation of age-associated increases in oxidative stress, according to the researchers.

Pharmacokinetic studies show that dissolved C60 is absorbed by the gastro-intestinal tract and… read more

A weapon we can’t control

Stuxnet

The decision by the United States and Israel to develop and then deploy the Stuxnet computer worm against an Iranian nuclear facility late in George W. Bush’s presidency marked a significant and dangerous turning point in the gradual militarization of the Internet, says Misha Glenny, a visiting professor at the Columbia University School of International and Public Affairs, and the author of DarkMarket: Cyberthieves, Cybercopsread more

What happens during the brain’s ‘resting state’?

September 20, 2012

fMRI images

Over the past few years, some researchers have been adding a bit of down time to their study protocols, Nature News reports. While subjects are still lying in the functional magnetic resonance imaging (fMRI) scanners, the researchers ask them to try to empty their minds. The aim is to find out what happens when the brain simply idles. And the answer is: quite a lot.

Some circuits… read more

Unexplained communication between brain hemispheres without corpus callosum

October 21, 2011

Ag CC

Could the brain be using electromagnetic fields to communicate between hemispheres — the electromagnetic field theory of consciousness proposed by Johnjoe McFadden (School of Biomedical and Life Sciences, University of Surrey)?

Neuroscientists at the California Institute of Technology (Caltech) have made a puzzling finding: people born without a corpus callosum (which links the two hemispheres of the brain)  — a condition called agenesis… read more

How easy would it be to monitor the movement of everyone on the street by a private citizen with a few hundred dollars to spare?

Brendan O’Connor, 27, bought some plastic boxes and stuffed them with a $25, credit-card size Raspberry Pi Model A computer and a few over-the-counter sensors, including Wi-Fi adapters, The New York Times reports.

He connected each of those boxes to a… read more
