A Silicon Valley Supergroup Is Coming Together to Create an A.I. Device

Posted by in categories: mobile phones, robotics/AI

Since founding OpenAI in 2015, Sam Altman has spent many days thinking that the company’s generative artificial-intelligence products need a new kind of device to succeed. Since leaving Apple in 2019, Jony Ive, the designer behind the iPhone, iPod and MacBook Air, has been considering what the next great computing device could be.

Now, the two men and their companies are teaming up to develop a device that would succeed the smartphone and deliver the benefits of A.I. in a new form factor, unconstrained by the rectangular screen that has been the dominant computing tool of the past decade, according to two people familiar with the discussions…

“…Many tech executives believe the technology has the power to introduce a new paradigm in computing that they call “ambient computing.” Rather than typing on smartphones and taking photographs, they imagine a future device in the form of something as simple as a pendant or glasses that can process the world in real time, using a sophisticated virtual assistant capable of fielding questions and processing images.”

FTC Sues Amazon for Illegally Maintaining Monopoly Power

Posted by in categories: business, energy

The Federal Trade Commission and 17 state attorneys general today sued, Inc. alleging that the online retail and technology company is a monopolist that uses a set of interlocking anticompetitive and unfair strategies to illegally maintain its monopoly power. The FTC and its state partners say Amazon’s actions allow it to stop rivals and sellers from lowering prices, degrade quality for shoppers, overcharge sellers, stifle innovation, and prevent rivals from fairly competing against Amazon.

The complaint alleges that Amazon violates the law not because it is big, but because it engages in a course of exclusionary conduct that prevents current competitors from growing and new competitors from emerging. By stifling competition on price, product selection, quality, and by preventing its current or future rivals from attracting a critical mass of shoppers and sellers, Amazon ensures that no current or future rival can threaten its dominance. Amazon’s far-reaching schemes impact hundreds of billions of dollars in retail sales every year, touch hundreds of thousands of products sold by businesses big and small and affect over a hundred million shoppers.

“Our complaint lays out how Amazon has used a set of punitive and coercive tactics to unlawfully maintain its monopolies,” said FTC Chair Lina M. Khan. “The complaint sets forth detailed allegations noting how Amazon is now exploiting its monopoly power to enrich itself while raising prices and degrading service for the tens of millions of American families who shop on its platform and the hundreds of thousands of businesses that rely on Amazon to reach them. Today’s lawsuit seeks to hold Amazon to account for these monopolistic practices and restore the lost promise of free and fair competition.”

Alien life may evolve from radically different elements than human life did

Posted by in category: alien life

Ultimately, the researchers discovered 270 different cycles of autocatalytic reactions. “Autocatalysis may not be that rare, but instead it might be a general feature of many different environments, even those that are really different from Earth,” Kaçar said.

Most of the 270 cycles did not employ organic compounds. Some centered around elements that are absent or exceedingly rare in life on Earth, such as mercury, or the radioactive metal thorium. A number of cycles likely only happen under extremely high or low temperatures or pressures.

Brain-Belly Connection: Gut Health May Influence Likelihood of Developing Alzheimer’s

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

Could changing your diet play a role in slowing or even preventing the development of dementia? We’re one step closer to finding out, thanks to a new UNLV study that bolsters the long-suspected link between gut health and Alzheimer’s disease.

The analysis — led by a team of researchers with the Nevada Institute of Personalized Medicine (NIPM) at UNLV and published this spring in the Nature journal Scientific Reports — examined data from dozens of past studies into the belly-brain connection. The results? There’s a strong link between particular kinds of gut bacteria and Alzheimer’s disease.

UNLV study pinpoints 10 bacterial groups associated with Alzheimer’s disease, provides new insights into the relationship between gut makeup and dementia.

Machine learning model able to detect signs of Alzheimer’s across languages

Posted by in categories: biotech/medical, mobile phones, robotics/AI

The University of Alberta is 3rd in the world for AI research.

Researchers meet the challenge of developing a model that uses speech traits to detect cognitive decline, paving the way for a potential screening tool.

Researchers are striving to make earlier diagnosis of Alzheimer’s dementia possible with a machine learning (ML) model that could one day be turned into a simple screening tool anyone with a smartphone could use.

The human brain’s characteristic wrinkles help to drive how it works

Posted by in categories: engineering, internet, neuroscience, physics

The study’s authors compared the influence of two components of the brain’s physical structure: the outer folds of the cerebral cortex — the area where most higher-level brain activity occurs — and the connectome, the web of nerves that links distinct regions of the cerebral cortex. The team found that the shape of the outer surface was a better predictor of brainwave data than was the connectome, contrary to the paradigm that the connectome has the dominant role in driving brain activity. “We use concepts from physics and engineering to study how anatomy determines function,” says study co-author James Pang, a physicist at Monash University in Melbourne, Australia.

A model of the brain’s geometry better explains neuronal activity than a model based on the ‘connectome’.

Dementia: Daily dose of olive oil linked to better brain health

Posted by in categories: health, neuroscience

Opting for olive oil could reduce your risk of fatal dementia, according to a new study.

Participants who included half a tablespoon of olive oil in their daily diet were 28% less likely to die of dementia.

The study authors found that replacing a single teaspoon of margarine or mayonnaise with olive oil reduced the risk of fatal dementia by 8–14%.

Omega-3 fatty acids may slow age related hearing loss

Posted by in categories: biotech/medical, life extension

Hearing diminishes as we age — about 50% of adults 75 and over in the United States have disabling hearing loss.

Age-related hearing loss cannot currently be stopped.

Researchers from the University of Guelph and Tufts.

Cells in confinement and people in crowds have similar behaviors

Posted by in category: biotech/medical

On a rush-hour train or a crowded flight, you might draw your limbs in close, shrinking as people fill the space. As it turns out, living cells behave similarly in confinement, adjusting their size while growing alongside other cells in sheets of tissue.

John Devany, then a graduate student in the lab of biophysicist Margaret Gardel, had been studying epithelial monolayers—sheets of cells that form barriers in skin and coat internal organs—when he noticed something interesting about how the cells were dividing.

“The way people think about division is that a cell will grow to twice its size, divide, and repeat the cycle,” says Devany, the first author of the study, published in Developmental Cell. But in the epithelial tissue he was observing, division was proceeding as usual, but the daughter cells were ending up smaller than the mother. The team, collaborating with researchers from New York University, decided to investigate the mechanisms that control cell growth and cycle duration in tissue and discovered that the two processes are not directly coupled.

Dolphins learn the ‘names’ of their friends to form teams—a first in animal kingdom

Posted by in category: futurism

Like members of a street gang, male dolphins summon their buddies when it comes time to raid and pillage—or, in their case, to capture and defend females in heat. A new study reveals they do this by learning the “names,” or signature whistles, of their closest allies—sometimes more than a dozen animals—and remembering who consistently cooperated with them in the past. The findings indicate dolphins have a concept of team membership—previously seen only in humans—and may help reveal how they maintain such intricate and tight-knit societies.

Findings reveal the marine mammals have a sense of team membership.
