Fast, cheap water desalination using graphene

Graphene sheets with precise one-nanometer pores have potential to purify seawater more efficiently than existing methods
July 2, 2012


MIT researchers have invented a new kind of filtration material for desalination: sheets of graphene, a one-atom-thick form of the element carbon, which they say can be far more efficient and possibly less expensive than existing desalination systems.

The availability of fresh water is dwindling in many parts of the world, a problem that is expected to grow with populations. The world’s supply of seawater is virtually… read more

FDA OK’s ingestible sensor chip

Chip tracks adherence to oral medications, can report to caregiver
July 31, 2012

Injestible chip

Proteus Digital Health, Inc. announced Monday that the U.S. Food and Drug Administration (FDA) has cleared its ingestible sensor for marketing as a medical device.

The ingestible sensor (formally referred to as the Ingestion Event Marker or IEM) is part of the Proteus digital health feedback system, an integrated, end-to-end personal health management system designed to help improve patients’ health habits and connections to caregivers.… read more

Ultrasound-released nanoparticles may help diabetics avoid the needle

November 25, 2013

New technique allows diabetics to control insulin release with an injectable nano-network and portable ultrasound device.

A new nanotechnology-based technique for regulating blood sugar in diabetics could give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections — rather than using needles to give themselves multiple insulin injections each day.

A patient who has type 1 or advanced type 2 diabetes needs additional insulin, a hormone that transports glucose — or blood sugar — from… read more

Is your smartphone making you stupid?

A study by University of Waterloo researchers suggests that smartphone users who are intuitive thinkers — more prone to relying on gut feelings and instincts when making decisions — frequently use search engines rather than their own brainpower.

“They may look up information that they actually know or could easily learn, but are unwilling to make the effort to actually think about it,” said Gordon Pennycook, co-lead author of… read more

Commercial asteroid hunters announce plans for new robotic exploration fleet

World’s first fleet of asteroid-hunting spacecraft announced by Deep Space Industries
January 22, 2013


Deep Space Industries (DSI) announced Monday night that it will send a fleet of asteroid-prospecting spacecraft out into the solar system to hunt for resources to accelerate space development to benefit Earth.

These “FireFly” spacecraft utilize low-cost cubesat components and get discounted delivery to space by ride-sharing on the launch of larger communications satellites.

“This is the first commercial campaign to explore the small… read more

Math ability requires hemisphere crosstalk in the brain

Could special training in improving hemispheric cross-communication improve math abilities? What kinds of devices or exercises would be most effective?
August 31, 2012

Numerical and Arthimetic Tasks

The strength of communication between the left and right hemispheres of the brain predicts performance on basic arithmetic problems, a new study by researchers at UT Dallas’ Center for Vital Longevity, Duke University, and the University of Michigan has found.

The findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia — an… read more

Pirate island attracts more than 100 startup tenants

May 9, 2012


More than 100 international tech companies have registered their interest in floating geek city Blueseed, to be launched next year in international waters outside of Silicon Valley.

The visa-free, start-up-friendly concept launched late last year aims to create a fully commercial technology incubator where global entrepreneurs can live and work in close proximity to the Valley, accessing VC funding and talent as required.

Why Earth remains capable of supporting life despite CO2 greenhouse gas emissions

It's all in the rocks
March 23, 2014


“Fresh” rock — nature’s atmospheric carbon dioxide regulator — explains why the Earth has become neither sweltering like Venus nor frigid like Mars. So say researchers from USC and Nanjing University in China.

Scientists have long known that “fresh” rock pushed to the surface via mountain formation effectively acts as a kind of sponge, soaking up the greenhouse gas CO2.

Left unchecked, however, that process would… read more

Human muscle, regrown on animal scaffolding

September 17, 2012

Sergeant Strang has grown new leg muscle thanks to a thin sheet of material from a pig, The New York Times reports.

The material, called extracellular matrix, is the natural scaffolding that underlies all tissues and organs, in people as well as animals. It is produced by cells, and for years scientists thought that its main role was to hold them in their proper position.

But… read more

Solar-powered 3-D printer prints glass from sand

June 29, 2011

Solar Sinter

Markus Kaiser’s  solar sintering project explores the potential of desert manufacturing, where energy and material occur in abundance.

In this experiment, sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, combining natural energy and material with high-tech production technology.

His work with solar-sintering aims to raise questions about the future of manufacturing and the use of solar energy.… read more

Exercise reorganizes the brain to reduce stress and anxiety

July 5, 2013


Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a Princeton University research team.

The researchers report in the Journal of Neuroscience that when mice allowed to exercise regularly experienced a stressor — exposure to cold water — their brains exhibited a spike in the activity of neurons… read more

Nanoparticles reprogram immune cells to fight cancer

August 16, 2013

mitochondria-targeted NPs

Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer.

However, most cancerous cells are able to avoid detection by the immune system because they so closely resemble normal cells.

That leaves the cancerous cells free to multiply and grow into life-threatening tumors while the body’s… read more

First human brain-to-brain interface

August 28, 2013


University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other… read more

A self-driving car equipped by GM spinoff Delphi Automotive completed today a historic, 3,500-mile journey across the U.S. from San Franscisco to New York.

The trip demonstrated the full capabilities of its active safety technologies with the longest automated drive ever attempted in North America. The coast-to-coast trip, launched in San Francisco on March 22, covered approximately 3,500 miles.

Demonstrated on the streets of Las Vegas at… read more

Catching up with Nevada, it will be legal for autonomous cars to drive in California, probably within the next five years, if Gov. Brown signs SB 1298, just passed by the California Senate, the San Jose Mercury reports.

The bill charges the DMV by January 2015 with determining standards for vehicles and rules.

Automakers would have to get their vehicles approved by the state, and then licensed… read more
