The Oxford Martin Commission for Future Generations has launched a report, Now for the Long Term, on the successes and failures in addressing global challenges over recent decades.

Published by the Oxford Martin School at Oxford University, the report calls for a radical shake-up in politics and business to deliver progress on climate change, reduce economic inequality, improve corporate practices, and address the chronic… read more

Georgia Tech professor proposes another alternative to the Turing test

The Lovelace 2.0 Test of Artificial Creativity and Intelligence assesses a computer's capacity for human-level intelligence by its ability to create, rather than to converse or deceive
November 20, 2014

But would mathematician-programmer Countess Lady Lovelace have approved?

Georgia Tech associate professor Mark Ried has developed a new kind of “Turing test” — a test proposed in 1950 by computing pioneer Alan Turing to determine whether a machine or computer program exhibits human-level intelligence.Most Turing test designs require a machine to engage in dialogue and convince (trick) a human judge that it is an actual person. But creating certain types of art also requires intelligence, leading Reid to consider… read more

Plant bacteria breakthrough enables crops worldwide to take nitrogen from the air

"N-Fix" can replace expensive and environmentally damaging nitrate fertilizers
August 1, 2013

Professor Ted Cocking from University of Nottingham with a plant grown using nitrogen fixation N Fix technology

The University of Nottingham scientists have developed a new technology that would enable all of the world’s crops to take nitrogen from the air, instead of requiring expensive and environmentally damaging fertilizers.

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital for plants to survive and grow. However, only a very small number of plants, most notably legumes (such as peas,… read more

The first person to undergo a head-transplant operation will be Valery Spiridinov, The Independent reports. The procedure will be performed by controversial Italian doctor Sergio Canavero, MD.

Canavero hopes to remove Spiridinov’s head (he’s suffering from a wasting or degenerative disease) and transplant it onto the body of someone who is brain-dead but still has a functioning body,

In a 2013 paper in open-access journal… read more

Earth-like planets are right next door

Life on such a planet would be "much older and more evolved than life on Earth"

Six percent of red-dwarf stars have habitable, Earth-sized planets, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found.

Red dwarfs are the most common stars in our galaxy; about 75 percent of the closest stars are red dwarfs. The closest Earth-like planet could be just 13 light-years away, Harvard astronomer and lead author Courtney Dressing calculated.

Given tablets but no teachers, Ethiopian children teach themselves

October 29, 2012

Earlier this year, OLPC workers dropped off closed boxes containing the tablets, taped shut, with no instruction. “I thought the kids would play with the boxes. Within four minutes, one kid not only opened the box, found the on-off switch … powered it up. Within five days, they were using 47 apps per child, per day.

Within two weeks, they were singing ABC songs in the village, and within five months, they had hacked Android,” Negroponte said. “Some idiot in our organization or in the Media Lab had disabled the camera, and they figured out the camera, and had hacked Android.” ….read more

Save Our Crops Coalition, a group representing fruit and vegetable growers and canners, has dropped its opposition to regulatory approval of genetically engineered crops resistant to the powerful herbicide 2,4-D, The New York Times reports.

The group said Dow Agrosciences, a subsidiary of Dow Chemical, the crops’ developer, had agreed to take… read more

At last: a low-cost, professional-grade light-based 3D printer

September 27, 2012

form1

Formlabs’ new Form 1 3D printer could bring professional-grade 3-D prints to the home workshop.

Desktop 3-D printing has largely been the domain of extrusion-based machines like MakerBot’s Replicator and homebrew RepRap designs.

These lag behind the capabilities of pricier, professional stereolithography devices, where UV light cures incredibly thin layers of resin to create objects on par with manufactured goods.

Developing this type of printer at a… read more

US State Dept. orders removal of 3D-printed gun designs

May 10, 2013

liberator_1

The U.S. State Department has demanded designs by Defense Distributed for a 3D-printed gun be taken offline because publishing them online may breach arms-control regulations, Forbes reports.

The order to remove the blueprints for the plastic gun comes after they were downloaded more than 100,000 times.

However, the files were actually being served by Mega, the New Zealand-based storage service created by ex-hacker entrepreneur Kim… read more

Existing cropland could feed 4 billion more

An abundant supply of food for a hungry world, hidden in plain sight

cropland

Reallocating croplands away from fuels and animal feed could boost food available for people by 70 percent without clearing more land, new research from the Institute on the Environment at the University of Minnesota research shows

The world’s croplands could feed 4 billion more people than they do now just by shifting from producing animal feed and biofuels to producing exclusively food for human consumption,… read more

NSA admits wrongly adding 16,000 phone numbers to ‘alert list’

The National Security Agency admitted in documents released Tuesday that it had wrongly put 16,000 phone numbers on an “alert list” so their incoming calls could be monitored, a mistake that a judge on the secret surveillance court called a “flagrant violation” of the law, the Los Angeles Times reports.

Computational biologists at Baylor College of Medicine and analytics experts at IBM research are developing a powerful new tool called the Knowledge Integration Toolkit (KnIT) that promises to help research scientists deal with the more than 50 million scientific papers available in public databases — with a new one publishing nearly every 30 seconds.

The goal: allow researchers pursuing new scientific studies to mine all available medical… read more

First map of how the brain organizes everything we see

December 20, 2012

Semantic_space_small

How do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to organize all the categories of objects and actions that we see, and they have created the first interactive map of how the brain organizes these groupings.

Continuous semantic space

Attention seniors: French scientists have developed a process that permanently dyes white hair without harmful chemicals.

Philippe Walter and colleagues soaked white hairs in a solution containing fluorescent gold nanoparticles.

The hairs turned pale yellow and then darkened to a deep brown. The color remained even after repeated washings.

Using an electron microscope, the scientists confirmed that the particles were forming inside the hairs’ central core cortex.… read more

“By 2040 or so, astronomers will have scanned enough star systems to give themselves a great shot of discovering alien-produced electromagnetic signals,” said Seth Shostak, Senior Astronomer at the SETI Institute, Space.com reports.

Shostak spoke at the NASA Innovative Advanced Concepts (NIAC) symposium on Feb. 6 at Stanford University.

He will also speak at the Contact conference on March 21–23… read more
