The Inspiration Mars Foundation,  led by Dennis Tito, the first space tourist, will announce on Wednesday Feb. 27 a planned mission to Mars in 2018.

The mission would take advantage of a unique window of opportunity; the orbits of Earth and Mars will be closely aligned. The round-trip journey would start in January 2018 and take 501 days.

No details are available yet on how they… read more

Low-carbon technologies ‘no quick-fix,’ say researchers

February 16, 2012

Wind power

A drastic switch to low carbon-emitting technologies, such as wind and hydroelectric power, may not yield a reduction in global warming until the latter part of this century, research published today by the Institute of Physics suggests.

Furthermore, it states that technologies that offer only modest reductions in greenhouse gases, such as the use of natural gas and perhaps carbon capture and storage, cannot substantially reduce climate… read more

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

How to prevent diseases of aging

July 24, 2014

By 2050, the number of people aged over 60 years is projected to be five times that in 1950 (credit: Luigi Fontana, Brian K. Kennedy, and and Valter D. Longo/Nature)

By 2050, the number of people over the age of 80 will triple globally, which could come at great cost to individuals and economies.

Unfortunately, medicine focuses almost entirely on fighting chronic diseases in a piecemeal fashion as symptoms develop, researchers writing in the journal Nature say. Instead, more efforts should be directed to promoting interventions that have the potential to prevent multiple chronic diseases and extend healthy lifespans.… read more

Lit Motors will shake up the electric vehicle market with its two-wheeled, untippable C-1

September 12, 2012

c1_lil_motors

Imagine a vehicle that’s smaller than a Smart Car, nearly a third of the price of a Nissan Leaf ($32,500), safer than a motorcycle with a range capacity that just lets you drive and won’t ever tip over.

What you get is Lit Motors‘ C-1, the world’s first gyroscopically stabilized, two-wheeled all-electric vehicle, which launched at TechCrunch Disrupt in San Francisco today, writes Peter Ha on read more

Minnesota bans free online education, caves to Internet pressure

October 21, 2012

Minnesota’s Office of Higher Education was forced by public pressure Friday to cancel its bizarre bureaucratic decision to prohibit free online college courses offered through Coursera and other websites, Slate reported Friday.

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

Forget electric cars, this one runs on compressed air

August 19, 2012

tata airpod car 2

India’s Tata Motors is pushing technology for compressed air to power cars forward with its project to build “Airpods zero-pollution, cute-as-a-bug smartcars that zip along at 40 m.p.h. via the magic of squeezed air, The Atlantic Cities reports.

They are built with pneumatic motors that use pressurized air to drive pistons.

The mid-sized model fits three passengers, although one must face backward.… read more

Most realistic android infant?

July 29, 2012

Affetto-internalmech2

Osaka University’s Asada Lab roboticists say Affetto is the most realistic infant robot ever made, thanks to the 12 degrees of freedom of its head, its smile, and the 20 flexible pneumatic actuators to move its arms, neck, and spine.

What do you think? Does this bypass the uncanny valley yet? (Warning: fast-forward to :58 to bypass the scary part.)… read more

New evidence on how compound found in red wine can help prevent cancer

How resveratrol can prevent cancer, heart disease and diabetes
December 7, 2012

University of Leicester scientists have presented groundbreaking new evidence about how a chemical found in red wine can help prevent cancer.

Experts from around the world attended Resveratrol 2012, a major conference at the University to assess the latest advances in the study of resveratrol — a compound found in the skins of red grapes.

The conference featured new findings based on… read more

Neuroscientists plant false memories in the brain

MIT study also pinpoints where the brain stores memory traces, both false and authentic
July 26, 2013

memory_traces_hippocampus

The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

In a step toward understanding how these faulty memories arise, MIT neuroscientists have shown that they can plant false memories in the brains of mice.

They also… read more

Growing human organs inside pigs in Japan

January 6, 2014

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

Amazon hopes to use autonomous octocopter drones to deliver small packages to customers within 30 minutes, Amazon CEO Jeff Bezos announced Sunday in a 60 Minutes interview with Charlie Rose.

Amazon says putting the new Amazon Prime Air service into commercial use “will take some number of years as we advance the technology and wait for the… read more

Lab-grown model 3D brains

"Cerebral organoids” can model complex human brain disorders and the earliest stages of brain development
August 30, 2013

organoid

Scientists in an Austrian laboratory have developed complex human brain tissue made from stem cells in a laboratory 3D culture system for the first time. The method allows induced pluripotent stem (iPS) cells (which have the potential to differentiate into almost any cell in the body) to develop into “cerebral organoids” — or “mini brains.”

These mini brains, which are a few millimeters across, develop several… read more

Boston Dynamics’ new running robot: WildCat

October 6, 2013

WildCat2

Boston Dynamics has unleashed Cheetah as “WildCat” — a four-legged robot being developed to run fast on all types of terrain.

So far, WildCat has run at about 16 mph on flat terrain using bounding and galloping gaits — still slower than tethered Cheetah, with a top speed of 28.3 mph. Boston Dynamics is developing WildCat with funding from DARPA’s M3 program. (To… read more
