DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.
DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more
Why is it that within a homogeneous population of the same species, some individuals live three times as long as others?
EPFL researchers investigated this question and found the mechanism responsible for aging hidden deep within mitochondria.
The were able to dramatically slow aging down in worms by administering antibiotics to the young, achieving a lifespan extension of 60 percent.

University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone (Android version in the works) that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules.
Having such sensitive biosensing capabilities in the field could enable on-the-spot tracking of groundwater contamination, map the spread of pathogens (using the phone’s GPS),… read more
“I’ve experienced both sides” of the privacy debate on Google Glass, Nick Bilton writes in The New York Times.
But other gadgets have plenty of privacy-invading potential too, he says. Memoto, a tiny, automatic camera that looks like a pin you can wear on a shirt, can snap two photos a minute and later upload it to an online service.
Apple is… read more
Google plans to build and help run wireless networks in emerging markets such as sub-Saharan Africa and Southeast Asia, connecting a billion or more new people to the Internet.
The goal is to provide Internet access to dwellers outside of major cities where wired Internet connections aren’t available, The Wall Street Journal reported Friday.
As part of the plan, Google has also worked on making special balloons or… read more
University of Texas Arlington scientists have discovered a way to control the growth or repair of neurons and neuron circuits, using a non-invasive “neuronal beacon” (near-IR laser beam) — essentially rewiring brains, or even creating new ones.
This major discovery, just published today in Optics Letters, promises to enable several new applications, UT Arlington assistant professor of physics Samarendra Mohanty said in an exclusive interview with KurzweilAI:
A bioresorbable splint used for first time, successfully stopped life-threatening tracheobronchomalacia, a case featured in New England Journal of Medicine.
Every day, a baby, Kaiba, stopped breathing, his collapsed bronchus blocking the crucial flow of air to his lungs. Parents April and Bryan Gionfriddo watched helplessly.
They found hope at the University of Michigan, where a new, bioresorbable device that could help Kaiba was… read more
Scientists from the University of Southampton have developed a microfluidic electrophysiological device called a NeuroChip that records the neural activity in the microscopic worm Caenorhadbitis elegans (C. elegans) — the worm equivalent of an EEG —.to help test the effects of drugs.
How to record a worm’s ‘EEG’
With the NeuroChip, you feed the worm into a narrow, fluid-filled channel that tapers at… read more
Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have used the unique capabilities of the Lab’s Advanced Light Source (ALS) to advance a new concept in magnetic memory.
“What we’re working on now could make these gadgets perform hundreds of times better and also be a hundred times more energy efficient,” says the Lab’s Peter Fischer.
Four memory states
Magnetic memories store… read more
Bitcoin is gaining traction outside its existing community of enthusiastic early adopters.
An estimated 1,100 people attended Bitcoin 2013, the first large conference dedicated to Bitcoin, MIT Technology Review reports. The conference also showed that Bitcoin has begun to attract the backing of conventional technology industry investors, who have sunk millions of dollars into a handful of Bitcoin startups.
In the Bitcoin system,… read more
Researchers have worked out the practical details for an autonomous spacecraft navigation system using signals from pulsars in essentially the same way that we use GPS satellites to navigate on Earth, MIT Technology Review reports.
A pulsar is a rotating neutron star that emits a beam of electromagnetic radiation at a very precise interval between pulses that ranges from milliseconds to seconds.
By measuring the arrival time… read more
Researchers at the University of Missouri have found a way to create radioactive nanoparticles that target lymphoma tumor cells wherever they may be in the body.
Michael Lewis, an associate professor of oncology in the MU College of Veterinary Medicine, says being able to target secondary tumors is vital to successfully treating patients with progressive cancers.
“Depending on the type of cancer, primary tumors… read more
New data show that the NeuroStar TMS (transcranial magnetic stimulation) Therapy System induced statistically and clinically meaningful response and remission in patients with Major Depressive Disorder (MDD) during the acute phase of therapy, and the effects were maintained through one year of treatment.
At the end of acute treatment, 62 percent of patients achieved symptomatic improvement while 41 percent reported complete remission. At 12 months,… read more
When did the first stars and galaxies form in the universe? How brightly did they burn their nuclear fuel?
Scientists will seek to gain answers to these questions with the launch of the Cosmic Infrared Background ExpeRIment (CIBER) on a Black Brant XII suborbital sounding rocket between 11 and 11:59 p.m. EDT, June 4 from the Wallops Flight Facility in Virginia.
Jamie Bock, CIBER principal investigator… read more
Scientists from Nanyang Technological University (NTU) and Lund University, Sweden, have bioengineered a novel molecule proven to successfully kill tumor cells.
This molecule is based on a natural protein present in human breast milk, which has been found to have strong and wide-ranging tumor killing properties when bound to certain lipids. Lipids are organic molecules like amino acids and carbohydrates, made up of carbon and… read more
