November 19, 2015

selfie ft

Robotics company Neurala has combined facial-recognition and drone-control mobile software in an iOS/Android app called “Selfie Dronie” that enables low-cost Parrot Bebop and Bebop 2 drones to take hands-free videos and follow a subject autonomously.

To create a video, you simply select the person or object and you’re done. The drone then flies an arc around the subject to take a video selfie (it moves with the… read more

Finding ET may require giant robotic leap

April 24, 2012

NGC Galaxy

Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life and perhaps clean up space debris in the process, according to John D. Mathews, professor of electrical engineering at Penn State.

“The basic premise is that human space exploration must be highly efficient, cost effective, and autonomous as placing humans beyond low Earth orbit is fraught with political… read more

Hawking offers new solution to ‘black hole information paradox’

New hope if you fall into a black hole

Addressing a current controversy in physics about information in black holes, “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon.”

The event horizon is a boundary around a black hole beyond which events cannot affect an outside observer, also known as “the point of no return” — where gravitational pull… read more

A small asteroid named 2012 DA14 will pass inside the geosynchronous satellite ring on February 15, but the orbit will be no closer to the Earth’s surface than 3.2 Earth radii , according to NASA JPL..

Although its size is not well determined, this near-Earth asteroid is thought to be about 45 meters in diameter.

Advanced Cell Technology, Inc. (ACT) has confirmed that the vision of a patient enrolled in a clinical investigation of the company’s retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs) has improved from 20/400 to 20/40 following treatment.

ACT is currently enrolling patients in three clinical trials in the U.S. and Europe for treatment of Stargardt’s macular dystrophy (SMD) and dry age-related… read more

A world record for highest-surface-area materials

Greatly expands storage density for natural gas (for vehicles), light harvesting, and drug delivery
September 13, 2012

NU-110

Northwestern University researchers have broken a world record by creating two new synthetic materials with the greatest amount of surface areas reported to date.

Named NU-109 and NU-110, the materials belong to a class of crystalline nanostructure known as metal-organic frameworks (MOFs) that are promising vessels for natural-gas and hydrogen storage for vehicles, and for catalysts, chemical sensing, light harvesting, drug delivery, and other uses requiring a large… 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

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

graphene-desalination

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

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_indistries_logo

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

Is your smartphone making you stupid?

March 6, 2015

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

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

White House announces new US ‘open access’ policy

A "massive sellout" to big publishers, with 12-month embargo on research, says a PLOS founder

The White House said Friday that publications from taxpayer-funded research should be available to you, but only after a year’s delay.

“The Obama Administration is committed to the proposition that citizens deserve easy access to the results of scientific research their tax dollars have paid for,” the memo said.

But that doesn’t mean fast access. And the policy would, strangely, only apply to Federal agencies with more… read more

A new method for producing clean hydrogen

May 23, 2013

TEM_image_Au-a-Fe2O3_catalyst

Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.

While hydrogen is ubiquitous in the environment, producing and collecting molecular hydrogen for transportation and industrial uses is expensive and complicated. Just as importantly, a byproduct of most current methods of producing hydrogen is carbon monoxide, which is… read more
