Is faster-than-light travel possible?

July 23, 2013

Alcubierre warp drive

Engineers at NASA Johnson Space Center are designing instruments to find out, by slightly warping the trajectory of a photon and measuring the distance it travels, The New York Times reports.

Inspiration for the research came from Mexican physicist Miguel Alcubierre, who proposed in 1994 a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to… 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

The European Commission has selected the two research proposals it will fund to the tune of half-a-billion euros ($650 million U.S.) each, after a two-year, high-profile contest, Nature News reports.

The Human Brain Project, led by neuroscientist Henry Markram at the Swiss Federal Institute of Technology (EPFL) in Lausanne, plans to simulate the human brain in a supercomputer. (See “Brain inread more

iSpy vs. gSpy

We are all being watched, whether we like it or not.

It is a battle between you and the government — like Mad Magazine’s Spy vs. Spy comic, but it’s gSpy vs. iSpy, Andy Kessler, author of Eat People, writes in The Wall Street Journal.

There are thousands of toll booths at bridges and turnpikes across America recording your license plate. There are 4,214 red-light cameras… read more

Biotech is thrusting us into new political territory

August 29, 2012

Human_fetus_10_weeks_with_amniotic_sac

Stem cells, embryo research and synthetic biology are just a few of the issues that will force strange new political alliances, University of Pennsylvania bioethicist Jonathan D. Moreno writes in New Scientist.

The new biology, or biotechnology — including stem cells, embryo research, synthetic biology and reproductive technology — has unprecedented power to change basic life processes.

One recent example is the controversy over the “three-parent… read more

IBM launches functioning brain-inspired chip

Operates at 46 billion “synaptic operations” per second per watt; 100 trillion "synapses" planned, matching the approximate number in the human brain

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

Internet activists on red alert ahead of United Nations conference

How the ITU could put the Internet behind closed doors
November 16, 2012

R.I.P._Internet

Internet activists are warning that next month’s meeting of the International Telecommunications Union, a United Nations body charged with overseeing global communications, may have significant and potentially disastrous consequences for everyday Internet users, Mashable reports.

Called the World Conference on International Telecommunications, the meeting is intended to update some of the aging international law that governs the flow of information online. The meeting is mostly closed to… 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

Drugs

“After experiencing drastic changes in my environment, I looked for other experiences that might profoundly affect my perception of the self. So I devised another experiment where everyday I took a different drug and drew myself under the influence.

“Within weeks I became lethargic and suffered mild brain damage. I am still conducting this experiment but over greater lapses of time.  I only take drugs that are given… read more

A nanocopter camera that follows you around, streaming video to your smartphone

February 14, 2013

MeCam

Always Innovating is developing a $49. tiny flying video camera called the MeCam, due out in 2014.

The camera streams live video to your smartphone, allowing you to stream or upload videos. A nanocopter with 4 spinning rotors houses the camera, with an ARM Cortex-A9 processor, 1GB of RAM, WiFI, and Bluetooth.

The MeCam launches from the palm of a hand and hovers instantly. It streams… read more

Are you ready for the Internet of Cops?

March 3, 2014

FirstNet-challenges

FirstNet — a state-of-the-art communications network for paramedics, firemen and law enforcement at the federal, state and local level — will give cops on the streets unprecedented technological powers, and possibly hand over even more intimate data about our lives to the higher ends of the government and its intelligence agencies, Motherboard reports.

According to a series of presentation slides from December last year, FirstNet… read more

A thin, flexible electrode developed at the University of Michigan is 10 times smaller than the nearest competition and could make long-term measurements of neural activity practical.

This kind of technology could also be used eventually to send brain-computer-interface (BCI) signals to prosthetic limbs, overcoming inflammation caused by larger electrodes, resulting in damage to both the brain and the electrodes.

Existing electrodes are stiff and enormous… read more

New cosmic background radiation map challenges some foundations of cosmology

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

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
July 3, 2014

USC professor Sri Narayan's research focuses on the fundamental and applied aspects of electrochemical energy conversion and storage to reduce the carbon footprint of energy use and by providing energy alternatives to fossil fuel (credit: USC Photo/Gus Ruelas)

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

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