August 15, 2013

A University of Michigan animal study shows that shortly after clinical death, in which the heart stops beating and blood stops flowing to the brain, rats display brain activity patterns characteristic of conscious perception.

The “near-death experience” (NDE) reported by cardiac arrest survivors worldwide may be grounded in science, according to research at the University of Michigan Health System.

Psychedelic drugs should be legally reclassified, says psychiatrist

Pre-1967 research showed "beneficial change in many psychiatric disorders"
May 28, 2015

Psychedelic drugs such as LSD are much less harmful than claimed and should be legally reclassified to allow further research on their medical use, says James Rucker, a psychiatrist and honorary lecturer at the Institute of Psychiatry, Psychology and Neuroscience, King’s College London.

These substances “were extensively used and researched in clinical psychiatry” before their prohibition in 1967 and many trials of these drugs in the 1950s and 1960s… 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

Elon Musk wants to enhance us as superhuman cyborgs to deal with superintelligent AI

April 21, 2017

(credit: Neuralink Corp.)

It’s the year 2021. A quadriplegic patient has just had one million “neural lace” microparticles injected into her brain, the world’s first human with an internet communication system using a wireless implanted brain-mind interface — and empowering her as the first superhuman cyborg. …

No, this is not a science-fiction movie plot. It’s the actual first public step — just four years from now — in Tesla CEO Elon… read more

How to save money by making stuff with 3D printers

July 31, 2013

RepRap print

A Michigan Technological University researcher is predicting that personal manufacturing, like personal computing before it, is about to enter the consumer mainstream in a big way.

“For the average American consumer, 3D printing is ready for showtime,” said Associate Professor Joshua Pearce.

The reason is financial: the typical family can already save a great deal of money by making things with a 3D printer… read more

Spooky alignment of quasar axes across billions of light-years with large-scale structure

November 21, 2014

This artist's impression shows schematically the mysterious alignments between the spin axes of quasars and the large-scale structures that they inhabit that observations with ESO’s Very Large Telescope have revealed. These alignments are over billions of light-years and are the largest known in the Universe. The large-scale structure is shown in blue and quasars are marked in white with the rotation axes of their black holes indicated with a line around them. This picture is for illustration only and does not depict the real distribution of galaxies and quasars. (Credit: ESO/M. Kornmesser)

New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to… read more

Is it possible to develop “moral” autonomous robots with a sense for right, wrong, and the consequences of both?

Researchers from Tufts University, Brown University, and Rensselaer Polytechnic Institute think so, and are teaming with the U.S. Navy to explore technology that would pave the way to do exactly that.

“Moral competence can be roughly thought about as the ability to learn,… read more

‘We have detected gravitational waves’ — LIGO scientists

February 11, 2016

The gravitational-wave event on Sept. 14, 2015 at 09:50:45 UTC was observed by the two LIGO detectors in Livingston, Loiusiana (blue) and Hanford, Washington (orange). The matching waveforms represent gravitational-wave strain generated by the inferred merger of two inspiraling black holes. (credit: B. P. Abbott et al./PhysRevLett)

On Sept. 14, 2015 at 5:51 a.m. EDT (09:51 UTC) for the first time, scientists observed ripples in the fabric of spacetime called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe, the National Science Foundation and scientists at the LIGO Scientific Collaboration announced today. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window to the… read more

Google’s self-driving car prototype: no steering wheel, brake, or accelerator

May 30, 2014

Google car

Google is exploring what fully self-driving vehicles would look like without a steering wheel, accelerator pedal, or brake pedal. “Our software and sensors do all the work,” says the company.

The early prototypes have sensors that remove blind spots, and can detect objects out to a distance of more than two football fields in all directions, which is especially helpful on busy streets with lots… read more

Are jobs obsolete?

September 8, 2011

We need a new productivity-based model to cope with human work replaced by technology (case in point: U.S. Post Office vs. email), says Douglas Rushkoff in a special to CNN. It’s not about jobs, he says, it’s about productivity. Technology lets us bypass corporations, make our own work — a new model.

“The question we have to begin to ask ourselves is not how do we employ… read more
