A new material that can kill E. coli bacteria within 30 seconds has been developed by researchers at the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR in Singapore.

Triclosan, a common antibacterial ingredient found in many products such as toothpastes, soaps, and detergents to reduce or prevent bacterial infections, has been linked to making bacteria resistant to antibiotics, with adverse health effects. The European Union… read more

New cosmic background radiation map challenges some foundations of cosmology

March 22, 2013

Planck_CMB_large

The most detailed map ever created of the cosmic microwave background — the relic radiation from the Big Bang — acquired by ESA’s Planck space telescope, has been released, revealing features that challenge the foundations of our current understanding of the Universe and may require new physics.

  • The fluctuations in the CMB temperatures at large angular scales do not match those predicted by the

IBM announced today, August 7, the first computer chip to achieve one million programmable “neurons,” 256 million programmable “synapses,” and 46 billion “synaptic operations” per second per watt — simulating the function of neurons and synapses in the brain.*

Neurosynaptic. At 5.4 billion transistors, this low-power, production-scale “neurosynaptic” (brain-inspired) chip (the size of a postage stamp), is one of the largest CMOS chips ever built, IBM says.… read more

Travelers to Mars risk leukemia cancer, weakened immune function from radiation, NASA-funded study finds

Radiation encountered in deep space travel may increase the risk of leukemia cancer in humans traveling to Mars, NASA-funded researchers at the Wake Forest Institute for Regenerative Medicine and colleagues have found, using mice transplanted with human stem cells.

“Our results are troubling because they show radiation exposure could potentially increase the risk of leukemia,” said Christopher Porada, Ph.D., associate professor of regenerative medicine and… read more

Future Day: a new global holiday March 1

February 29, 2012

future_day

Why are nearly all our holidays focused on celebrating the past, or the cyclical processes of nature? Why not celebrate the amazing future we are collectively creating?

That’s the concept behind a new global holiday, Future Day (March 1), conceived by AI researcher Dr. Ben Goertzel.

Future Day 2012 gatherings are scheduled in more than a dozen cities, as well as in… read more

‘Neural dust’ brain implants could revolutionize brain-machine interfaces and allow large-scale data recording

July 17, 2013

Neural dust

In a potential neuroscience breakthrough, University of California Berkeley scientists have proposed a system that allows for thousands of ultra-tiny “neural dust” chips to be inserted into the brain to monitor neural signals at high resolution and communicate data highly efficiently via ultrasound.

The neural dust design promises to overcome a serious limitation of current invasive brain-machine interfaces (BMI): the lack of an implantable neural interface system that remains… read more

Queen Mary University of London researchers have developed a Google Play app called Phoney based on a mind-reading card trick, part of a research exploration into what can be achieved when human intelligence is replaced or assisted by machine intelligence.

The app arranges a deck of playing cards in such a way that a specific card picked by an audience member can beread more

John Moravec of Education Futures interviewed mathematician and science-fiction writer Vernor Vinge, noted for his foundational 1993 essay, “The Coming Technological Singularity.

“I’m still where I was in my 1993 essay that I gave at a NASA meeting, and that is that I define the Technological Singularity as being our developing, through technology, superhuman intelligence — or becoming, ourselves, superhuman intelligent through technology,” said Vinge.

Scott Summit created a 3D model of his ideal guitar and sent the computer design to 3D Systems, which used its massive 3D printers to transform the graphic model into an actual acoustic instrument that Summit can play, Bloomberg Businessweek reports.

As far as anyone seems to know, this is the first 3D-printed guitar on the planet, and it raises all kinds musical possibilities. “It’s rich and full and… read more

A strange lonely planet found without a star

The planet is extremely cold and faint, about 100 billion times fainter in optical light than the planet Venus. Most of its energy is emitted at infrared wavelengths.

An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago — -a newborn in planet lifetimes.

It was identified from its faint and unique heat signature by the … read more

On May 14, 2014, astronomers at Parkes Radio Telescope led by Emily Petroff at Swinburne University of Technology observed live an extremely short, sharp “fast radio burst” for 2.8 milliseconds at a microwave frequency of 1.4 GHz from an unknown source at an estimated distance of up to 5.5 billion light years from Earth. 24 seconds later, an email alert went out to astronomers at… read more

A new battery that’s cheap, clean, rechargeable, and organic

Could pave the way for renewable energy sources to make up a greater share of a country's energy generation by economically storing energy at night

Scientists at USC have developed a water-based organic battery that is long-lasting and built from cheap, eco-friendly components (no metals or toxic materials).

The new battery is intended for use in power plants, where it could make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed.

“The batteries last for about 5,000 recharge cycles, giving them an estimated… read more

Real-world stereotypes continue to exist in virtual worlds

Stereotypes related to gender and appearance that burden women in the real world could follow them into virtual ones, according to Penn State researchers.

In a study of how people interacted with avatars in an online game, women received less help from fellow players than men when they operated an unattractive avatar and when they used a male avatar, said T. Franklin Waddell, a doctoral candidate in massread more
