New AI systems on a chip will spark an explosion of even smarter devices

Posted by in categories: internet, mobile phones, robotics/AI

Artificial intelligence is permeating everybody’s lives through the face recognition, voice recognition, image analysis and natural language processing capabilities built into their smartphones and consumer appliances. Over the next several years, most new consumer devices will run AI natively, locally and, to an increasing extent, autonomously.

But there’s a problem: Traditional processors in most mobile devices aren’t optimized for AI, which tends to consume a lot of processing, memory, data and battery on these resource-constrained devices. As a result, AI has tended to execute slowly on mobile and “internet of things” endpoints, while draining their batteries rapidly, consuming inordinate wireless bandwidth and exposing sensitive local information as data makes roundtrips in the cloud.

That’s why mass-market mobile and IoT edge devices are increasingly coming equipped with systems-on-a-chip that are optimized for local AI processing. What distinguishes AI systems on a chip from traditional mobile processors is that they come with specialized neural-network processors, such as graphics processing units or GPUs, tensor processing units or TPUs, and field programming gate arrays or FPGAs. These AI-optimized chips offload neural-network processing from the device’s central processing unit chip, enabling more local autonomous AI processing and reducing the need to communicate with the cloud for AI processing.

Experts Sign Open Letter Slamming Europe’s Proposal to Recognize Robots as Legal Persons

Posted by in categories: ethics, law, robotics/AI

Over 150 experts in AI, robotics, commerce, law, and ethics from 14 countries have signed an open letter denouncing the European Parliament’s proposal to grant personhood status to intelligent machines. The EU says the measure will make it easier to figure out who’s liable when robots screw up or go rogue, but critics say it’s too early to consider robots as persons—and that the law will let manufacturers off the liability hook.

This all started last year when the European Parliament proposed the creation of a specific legal status for robots:

so that at least the most sophisticated autonomous robots could be established as having the status of electronic persons responsible for making good any damage they may cause, and possibly applying electronic personality to cases where robots make autonomous decisions or otherwise interact with third parties independently.

Go On A 4K Joyride Around The Moon, Courtesy of NASA

Posted by in category: space travel

We’re so close to getting (back) to the Moon, we can practically taste it. Let’s face it, the Moon is really cool, from it’s highlands down to its massive crater basins. Even Donald Trump is entranced, and has directed NASA to get us back there.

Well today, NASA’s got a little something to wet our whistle. Its Lunar Reconnaissance Orbiter (LRO) mission has been closely examining the Moon’s surface since June 2009, and has been beaming fascinating footage of our only natural satellite back to Earth since then.

Peptide-based biogenic dental product may cure cavities

Posted by in categories: biotech/medical, engineering, health

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

The research finding was first published in ACS Biomaterials Science and Engineering.

“Remineralization guided by peptides is a healthy alternative to current dental care,” said lead author Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.

FDA approves contact lenses that shade the sun

Posted by in category: biotech/medical

The lives of contact lens wearers just got a whole lot easier.

On Tuesday, the U.S. Food and Drug Administration approved the first that can act like sunglasses.

A special additive automatically darkens the lenses when exposed to bright light, while they become clear again in normal or dark lighting conditions.

Bad antibodies made good: The immune system’s secret weapon uncovered

Posted by in category: biotech/medical

In a world first, scientists from Sydney’s Garvan Institute of Medical Research have revealed how a population of ‘bad’ antibodies in the immune system — which are usually ‘silenced’ because they can harm the body — can provide crucial protection against invading microbes. The research was carried out in mice.

The ‘bad’ antibodies are known to react against the body’s own tissues and can cause autoimmune disease. For this reason, it was once thought that they were discarded by the immune system or that they were made inactive in the long term. However, the new findings show for the first time that ‘bad’ antibodies go through a rapid ‘redemption’ process and are activated when the body is faced with a disease threat that other antibodies cannot tackle.

As a result, the ‘redeemed’ antibodies no longer threaten the body, but instead become powerful weapons to fight disease — and particularly diseases that evade the immune system by disguising themselves to look like normal body tissue.

Breakthrough brings gene-editing medicine one step closer to patient applications

Posted by in categories: bioengineering, biotech/medical, genetics

Imagine a future where a guided biomachine put into your body seeks out defective gene sequences in each cell and edits in the correct information with precision accuracy.

It’s called gene editing, and University of Alberta researchers have just published a game-changing study that promises to bring the technology much closer to therapeutic reality.

“We’ve discovered a way to greatly improve the accuracy of gene-editing technology by replacing the natural guide molecule it uses with a synthetic one called a bridged nucleic acid, or BNA,” said Basil Hubbard, Canada Research Chair in Molecular Therapeutics and an assistant professor in the U of A’s Department of Pharmacology, who led the study.

Fart gas may help prevent dementia, heart disease: study

Posted by in categories: biotech/medical, health, neuroscience

Farts may stink to high heaven, but a new study suggests that the gas responsible for that foul odor may actually extend a person’s time on earth.

Scientists in the UK claim that hydrogen sulfide, the stinky compound that smells like rotten eggs which contributes to the flatulence stench, could have amazing health benefits.

Hydrogen sulfide can be toxic, but tiny amounts have been shown to help protect the mitochondria, which are known as the “powerhouses” of cells.

Researchers are one step closer to an effective anti-atherosclerosis vaccine

Posted by in category: biotech/medical

In the disease atherosclerosis, cholesterol-containing plaques form in vessel walls, causing arteries to narrow and greatly increasing the risk of heart attack and stroke. Currently, atherosclerosis is the number 1 killer worldwide, just ahead of cancer. Recent use of statin anti-cholesterol drugs has reduced cardiovascular events caused by atherosclerosis by 35%, but millions of individuals remain at risk. Hence, a desirable addition or alternative would be intervention to prevent plaque formation altogether.

A new paper published in Circulation by researchers at La Jolla Institute for Allergy and Immunology supports this possibility. It reports successful vaccination of atherosclerotic mice with a small chunk of protein snipped out of “bad cholesterol.” Vaccination reduced plaque levels in test mice, and other experiments with human blood samples identified the class of T cells likely responsible for positive outcomes. The paper suggests that a comparable strategy could form the basis of a human vaccine.

“We knew atherosclerosis had an inflammatory component but until recently didn’t have a way to counteract that,” says senior author Klaus Ley, M.D., professor and head of LJI’s Division of Inflammation Biology. “We now find that our vaccination actually decreases plaque burden by expanding a class of protective T cells that curb inflammation.”
