Researchers have achieved the world’s fastest internet data speed – enough to download 1000 HD movies in a split second – using a single optical chip. The research team recorded a data speed of 44.2 Terabits per second (Tbps). Importantly, these speeds were achieved by attaching their new device to existing fibre-optic technology. The team used a new device that replaces 80 lasers with a single piece of equipment known as a micro-comb. It acts like a rainbow made up of hundreds of high quality infrared lasers from a single chip, and each ‘laser’ has the capacity to be used as a separate communications channel.
Nvidia researchers taught an AI system to recreate the game of Pac-Man simply by watching it being played. There’s no coding involved, no pre-rendered images for the software to draw on. The AI model is simply fed visual data of the game in action along with the accompanying controller inputs and then recreates it frame by frame from this information. The resulting game is playable by humans. The imagery is blurry and it doesn’t seem like the AI managed to capture the exact behaviour of the game’s ghosts, but the basic dynamics of Pac-Man are all there: eat pellets, avoid ghosts, and try not to die.
A team of scientists is working on an aggressive new approach that involves a swarm of tiny, cancer-killing robots. The idea is to inject the nanobots, which are engineered to look and travel like white blood cells, into a patient’s veins and move them around inside the body with powerful magnets. The robots are coated in nickel and gold film as well as anti-cancer medications – if they spot a cancer cell, they can quickly drop their medication payload. The team says it will still be a long time before they can actually test the robots in humans as they need to develop a way to actually track the robot swarm inside a person first.
Researchers have now discovered a single part of the brain that appears to naturally stop pain in mice — and they think this “off-switch” could lead to more robust pain relief options in the future. They discovered that the anaesthesia drugs not only inhibited certain neurons in the animals’ brains but also activated some neurons. When the mice were made to feel pain, the CeAga neurons sent inhibitory (“off”) signals to 16 parts of the brain that play a role in pain processing. When the researchers then used light to trigger the CeAga neurons, the animals appeared to experience immediate pain relief.
Reliance has launched an online grocery service, JioMart, in a move aimed at rivalling Amazon.com’s local unit and Walmart Inc’s Flipkart in the huge Indian market. JioMart will deliver groceries in more than 200 towns across the country. Reliance launched a small pilot of JioMart deliveries in select areas of the Indian financial capital Mumbai, days after announcing that Facebook would spend $5.7 billion for 9.99 % stake in the company’s digital unit, Jio Platforms. That partnership will help Reliance roll out service for India’s grocers and small businesses by capitalising on India’s 400 million-strong user base for Facebook’s WhatsApp messaging service.
Netflix will ask customers who have not watched anything on the on-demand video streaming service in a year or more if they wish to maintain their subscription — and will cancel their membership if it does not hear back. “You know that sinking feeling when you realize you signed up for something but haven’t used it in ages? At Netflix, the last thing we want is people paying for something they’re not using,” the company said. The unusual move illustrates just how much confidence Netflix has on its loyal customer base. Most companies are happy to withdraw their cut from their members’ bank accounts or credit cards for as long as they can.
A US Navy warship has successfully tested a new high-energy laser weapon that can destroy aircraft and drones mid-flight, the US Navy says. A statement released by US Pacific Fleet Public Affairs included footage of the moment USS Portland “successfully disabled an unmanned aerial vehicle … with a Solid State Laser.” The Technology Maturation Laser Weapon System Demonstrator (LWSD) was developed by the Office of Naval Research. This was the first “system-level implementation of a high-energy class solid-state laser.”
League spokesman Mike Bass said the NBA and the National Basketball Players Association are “engaged in exploratory conversations” with the Walt Disney Company about a possible late-July restart to the season. “Our priority continues to be the health and safety of all involved, and we are working with public health experts and government officials on a comprehensive set of guidelines to ensure that appropriate medical protocols and protections are in place…It would be a single site for an NBA campus for games, practices and housing.”
