Scientists at the Universities of Sheffield and Sussex are embarking on an ambitious project to produce the first accurate computer models of a honeybee brain in a bid to advance our understanding of Artificial Intelligence (AI) and how animals think.

The team will build models of the systems in the brain that govern a honeybee’s vision and sense of smell. Using this information, the researchers… read more

Graphene micro-supercapacitors to replace batteries for microelectonics devices

Will power biomedical implants, active RFID tags, embedded micro-sensors, and flexible electronics
February 27, 2013

Micro-supercapacitor

UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate miniature graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries.

These micro-supercapacitors, made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into small devices, such as next-generation pacemakers.

The new cost-effective fabrication method holds promise for the… read more

Drug laws are ‘worst case of scientific censorship in modern times’

June 17, 2013

brain_psilocybin

Outlawing psychoactive drugs amounts to the worst case of scientific censorship in modern times, leading scientists have argued.

UN conventions on drugs in the 1960s and 1970s have not only compounded the harms of drugs but also produced the worst censorship of research for over 300 years. This has set back research in key areas such as consciousness by decades and effectively stopped the investigation of promising… read more

Scientists speculate on top-secret Mars Rover discovery

November 28, 2012

NASA’s Curiosity rover’s Sample Analysis at Mars (SAM) instrument has likely relayed some provocative findings, Space.com reports.

John Grotzinger, lead mission investigator for the Curiosity rover, set the rumors in motion during an interview with NPR last week, saying, “We’re getting data from SAM … this data is gonna be one for the history books. It’s looking really good.”

Most scientists contacted… read more

Blue Brain project accurately predicts connections between neurons

In a landmark paper, published this week in PNAS (forthcoming), the EPFL’s Blue Brain Project (BBP) has identified key principles that determine synapse-scale connectivity by virtually reconstructing (in supercomputer) a cortical microcircuit and comparing it to a mammalian sample.

These principles now make it possible to predict the locations of synapses in the neocortex, the researchers say.

“This is a major breakthrough,… read more

Non-invasive brain-to-brain interface: links between two brains

Direct communication between the brains of human and rat .... or between humans
April 8, 2013

brainstorm

We reported last month how Duke University researchers remotely linked the brains of two rats. Now researchers from the U.S and South Korea have have taken it a step further: a non-invasive functional link between the brains of different species (human and rat) — a brain-to-brain interface (BBI).

Researchers at Brigham and Women’s Hospital and Harvard Medical School set up a system intended to allow a human to… read more

3D printed meat development funded

August 17, 2012

Billionaire investor Peter Thiel’s philanthropic foundation has announced a six-figure grant for bioprinted meat, part of an ambitious plan to bring to the world’s dinner tables a set of technologies originally developed for creating medical-grade tissues, CNET reports.

The recipient of the Thiel Foundation’s grant, a Columbia, Mo.-based startup named Modern Meadow, is pitching bioprinted meat as a more environmentally-friendly way to satisfy… read more

The cosmological supercomputer

How the Bolshoi simulation evolves the universe all over again
October 3, 2012

cosmic_web

Most of the ordinary matter in the universe — the stuff that makes up all the atoms, stars, and galaxies astronomers can see — is invisible, either sprinkled throughout intergalactic space in tenuous forms that emit and absorb little light or else swaddled inside galaxies in murky clouds of dust and gas, Joel R. Primack writes in IEEE Spectrum.

When astronomers look out into the night… read more

A bucket-full of this material can absorb all the oxygen in a room

The stored oxygen can be easily released again whenever and wherever needed

A new crystalline material absorbs 160 times more oxygen than in the air around you — only a spoonful bucket-full (10 liters) of it is enough to suck up all the oxygen in a room, according to its developer, Professor Christine McKenzie in the Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark.

A few grains of this material might absorb enough oxygen from the… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

NewsImage-GeneRepair

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more

Tesla Autopilot predicts collision ahead seconds before it happens

Tesla autopilot predicts

Hans Noordsij, a Dutch Tesla driver, uploaded a Dec. 27 dashcam video that dramatically shows the new radar processing capacity of Tesla’s Autopilot and resulting auto-breaking, DarkVision Hardware reports. The system’s radar saw ahead of the car in front and tracked two cars ahead on the road. Note the audible warning a second or so before the accident.
