Scientists discover a new mechanism that prevents the proliferation of cancer cells

Posted by in categories: biotech/medical, genetics

Canadian researchers have discovered a new and direct molecular mechanism to stop cancer cells from proliferating. In the prestigious journal Nature Cell Biology, scientists from Université de Montréal show that a disruption of a fine balance in the composition of ribosomes (huge molecules that translate the genetic code into proteins) results in a shutdown of cancer cell proliferation, triggering a process called senescence.

“Ribosomes are complex machines composed of both RNAs and proteins that make all the proteins necessary for to grow,” said UdeM biochemistry professor Gerardo Ferbeyre, the study’s senior author. Cancer cells grow and proliferate relentlessly and thus require a massive amount of ribosomes, he explained. Growing cells must coordinate the production of both ribosomal RNAs and ribosomal proteins in order to assemble them together in strict proportion to each other.

“We were surprised, however, to find that if the production of ribosomal RNA– proportions are driven out of balance in a cancer cell, proliferation can be shut down by in a very simple and direct manner,” said Ferbeyre.

The reason thousands of Swedish people are inserting microchips into themselves

Posted by in categories: bioengineering, computing

Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards, and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many people, the idea of carrying a microchip in their body feels more dystopian than practical.

Some have suggested that Sweden’s strong welfare state may be the cause of this recent trend. But actually, the factors behind why roughly 3,500 Swedes have had microchips implanted in them are more complex than you might expect. This phenomenon reflects Sweden’s unique biohacking scene. If you look underneath the surface, Sweden’s love affair with all things digital goes much deeper than these microchips.

What if AI made actors immortal?

Posted by in categories: climatology, life extension, policy, robotics/AI

I’m not that interested in this on the movie end, because i think most movies already suck, and couldnt really get any worse.

AUDREY HEPBURN DIED in 1993, but in 2013 she nevertheless starred in an advertisement for Galaxy, a type of chocolate bar. She was shown riding a bus along the Amalfi coast before catching the eye of a passing hunk in a convertible. In 2016 Peter Cushing, who died in 1994, reprised his role as the villainous Grand Moff Tarkin in the Star Wars film “Rogue One”. Such resurrections are not new, but they are still uncommon enough to count as news. Yet advances in special effects—and, increasingly, in artificial intelligence (AI)—are making it ever easier to manufacture convincing forgeries of human beings.

In recent months this has led to concern that propagandists will use the technology to generate videos in which political figures appear to say compromising things. A video created by BuzzFeed, a news website, in April shows Barack Obama apparently saying “We’re entering an era in which our enemies can make it look like anyone is saying anything at any point in time,” for example. In May a Belgian political party produced a fake video of Donald Trump saying implausible things about Belgium’s climate policy. In both cases the video looks slightly off, and the voice is provided by an impersonator. But the technology is improving fast, prompting a dozen AI researchers to place bets on whether a fake video will disrupt America’s midterm elections later this year. (Tim Hwang, a Harvard academic, is overseeing the wager.)

Billionaire Ray Dalio: A.I. is widening the wealth gap, ‘national emergency should be declared’

Posted by in categories: economics, employment, government, information science, robotics/AI

It’s amusing that these people know where this is headed, but arent interested enough to stop it.

The co-chief investment officer and co-chairman of Bridgewater Associates shared his thoughts in a Facebook post on Thursday.

Dalio says he was responding to a question about whether machine intelligence would put enough people out of work that the government will have to pay people to live with a cash handout, a concept known as universal basic income.

An Overview of National AI Strategies

Posted by in categories: education, ethics, policy, robotics/AI

Dont really care about the competition, but this horse race means AI hitting the 100 IQ level at or before 2029 should probably happen.

The race to become the global leader in artificial intelligence (AI) has officially begun. In the past fifteen months, Canada, Japan, Singapore, China, the UAE, Finland, Denmark, France, the UK, the EU Commission, South Korea, and India have all released strategies to promote the use and development of AI. No two strategies are alike, with each focusing on different aspects of AI policy: scientific research, talent development, skills and education, public and private sector adoption, ethics and inclusion, standards and regulations, and data and digital infrastructure.

This article summarizes the key policies and goals of each national strategy. It also highlights relevant policies and initiatives that the countries have announced since the release of their initial strategies.

Robot able to mimic an activity after observing it just one time

Posted by in categories: robotics/AI, transportation

A team of researchers at UC Berkeley has found a way to get a robot to mimic an activity it sees on a video screen just a single time. In a paper they have uploaded to the arXiv preprint server, the team describes the approach they used and how it works.

Robots that learn to do things simply by watching a human carry out an action a single time would be capable of learning many more new actions much more quickly than is now possible. Scientists have been working hard to figure out how to make it happen.

‘Blind’ Cheetah 3 robot can climb stairs littered with obstacles

Posted by in categories: engineering, robotics/AI

The 90-pound mechanical beast — about the size of a full-grown Labrador — is intentionally designed to do all this without relying on cameras or any external environmental sensors. Instead, it nimbly “feels” its way through its surroundings in a way that engineers describe as “blind locomotion,” much like making one’s way across a pitch-black room.

“There are many unexpected behaviors the robot should be able to handle without relying too much on vision,” says the robot’s designer, Sangbae Kim, associate professor of mechanical engineering at MIT. “Vision can be noisy, slightly inaccurate, and sometimes not available, and if you rely too much on vision, your robot has to be very accurate in position and eventually will be slow. So we want the robot to rely more on tactile information. That way, it can handle unexpected obstacles while moving fast.”

Researchers will present the robot’s vision-free capabilities in October at the International Conference on Intelligent Robots, in Madrid. In addition to blind locomotion, the team will demonstrate the robot’s improved hardware, including an expanded range of motion compared to its predecessor Cheetah 2, that allows the robot to stretch backwards and forwards, and twist from side to side, much like a cat limbering up to pounce.

New cloaking technique lets light pass right on through

Posted by in category: futurism

The concept of an invisibility cloak sounds like pure science fiction, but hiding something from view is theoretically possible, and in some very-controlled cases it’s experimentally possible too. Now, researchers have developed a new device that works in a completely different way to existing cloaking technology, neatly sidestepping some past issues and potentially helping to hide everyday objects under everyday conditions.

We see objects because light bounces off them in a particular way before landing on your retinas, and they get their colors by reflecting more light of that particular color. The basic concept of cloaking objects involves finding ways to disrupt that process and build them into devices or metamaterials.
