The semiconductor industry's constant challenge is to make microchips that are smaller, faster, more powerful and more energy efficient — simultaneously.
On Thursday, IBM (IBM) announced it has created a 2-nanometer chip, the smallest, most powerful microchip yet developed.
Most computer chips powering devices today use 10-nanometer or 7-nanometer process technology, with some manufacturers producing 5-nanometer chips. The lower numbers denote smaller, more advanced processors. IBM's new chip uses 2-nanometer process technology, a huge leap forward for the components used to power everything from consumers' smart phones and appliances to supercomputers and transportation equipment.

"There are not many technologies or technological breakthroughs that end up lifting all boats," director of IBM Research Dario Gil said in an interview. "This is an example of one."

By shooting billions of lasers at the ground, scientists have uncovered evidence of a sophisticated civilization left by the ancient Maya who lived in the northern Yucatán Peninsula in what is now Mexico, a new study finds.

The laser survey revealed that in a region of the hilly northern Yucatán, known as the Puuc (pronounced "Pook"), the Maya built remarkable structures, including artificial reservoirs, more than 1,200 ovens, a handful of terraces for farming and nearly 8,000 platforms where houses were built. The ancient Maya also quarried the rock there, the laser scan revealed.

"It seems to have been a very prosperous area because we have all these masonry [stone] houses," study lead researcher William Ringle, a professor emeritus of anthropology at Davidson College in North Carolina, told Live Science. "It seems like people had access to what they needed."

NASA's Mars helicopter Ingenuity keeps pushing the aerial exploration envelope.

The 4-lb. (1.8 kilograms) chopper lifted off from the floor of Mars' Jezero Crater today at 10:49 a.m. EDT (1449 GMT), kicking off its fourth flight on the Red Planet.

Ingenuity achieved all of its main technology-demonstrating goals on flights one through three — which occurred on April 19, April 22 and April 25 — so the helicopter's handlers let it off the leash today. Ingenuity covered 872 feet (266 meters) of ground and reached a top speed of 8 mph (13 kph) during the 117-second jaunt, NASA officials said.

The Defense Advanced Research Projects Agency (DARPA) has picked three big space companies for the first phase of a larger project to test nuclear propulsion above low Earth orbit by 2025.

General Atomics, Blue Origin and Lockheed Martin each received contracts for the Demonstration Rocket for Agile Cislunar Operations (DRACO) program's first phase. While DARPA did not disclose the contract values in its announcement, media outlet Space News reported General Atomics received $22 million, Lockheed Martin $2.9 million and Blue Origin $2.5 million.

The teams were selected due to their ability to develop and deploy advanced systems for reactors, propulsion and spacecraft, DARPA officials said in a statement. The agency particularly emphasized the need for "rapid maneuver" for military systems but said this is difficult in space with conventional systems.

Virgin Galactic rolled out its newest spaceship Tuesday as the company looks to resume test flights in the coming months at its headquarters in the New Mexico desert.

Company officials said it will likely be summer before the ship—designed and manufactured in California—undergoes glide flight testing at Spaceport America in southern New Mexico. That will coincide with the final round of testing for the current generation of spacecraft, which will be the one that takes British billionaire and Virgin Galactic founder Sir Richard Branson to the fringes of space later this year.

In 2023, will civilians fly around the moon for the first time? According to Japanese entrepreneur Yusaku Maezawa, the answer is yes. He is bankrolling the DearMoon mission, which is intended to take a group of eight people to the moon on SpaceX's still-in-development Starship and loop around Earth's natural satellite on a six-day mission.

The project, announced by Maezawa and SpaceX CEO Elon Musk in 2018, originally planned to invite artists from around the world to experience. The criteria for "artists" was never clearly defined, but on Tuesday, in a new promotional video for the mission, Maezawa announced that DearMoon would be opened up to practically everyone across the globe.

"I began to think that maybe every single person who is doing something creative could be called an artist," he says in the video, which you can view below.

The price of bitcoin has crashed spectacularly following weeks of steady gains.

More than $10,000 was wiped from the cryptocurrency’s value in the space of just a few hours on Monday, taking its value below $50,000.

The price correction came after bitcoin hit a new all-time high above $58,000 on Sunday.

Bitcoin’s price fell to below $49,000 on Monday, though its remarkable gains meant it was still trading higher than it was one week ago.

Other major cryptocurrencies also experienced heavy losses, including Ethereum (ether), bitcoin cash, cardano and dogecoin.

Our thoughts are private – or at least they were. New breakthroughs in neuroscience and artificial intelligence are changing that assumption, while at the same time inviting new questions around ethics, privacy, and the horizons of brain/computer interaction.

Research published last week from Queen Mary University in London describes an application of a deep neural network that can determine a person’s emotional state by analyzing wireless signals that are used like radar. In this research, participants in the study watched a video while radio signals were sent towards them and measured when they bounced back. Analysis of body movements revealed “hidden” information about an individual’s heart and breathing rates. From these findings, the algorithm can determine one of four basic emotion types: anger, sadness, joy, and pleasure. The researchers proposed this work could help with the management of health and wellbeing and be used to perform tasks like detecting depressive states.

Today in an SEC filing, Tesla disclosed that it has acquired $1.5 billion in bitcoin, the popular cryptocurrency. Moreover, the company noted that it may also accept bitcoin in the future as a form of payment for its cars, though it did allow that there is some regulatory uncertainty around that effort.

As the news broke, the price of bitcoin instantly rose by around 7% to more than $40,000 per coin.

Tesla had previously telegraphed that it had an interest in the cryptocurrency, however to purchase such a large block of the coin is notable.

Filipinos continue to lead the world in terms of hours spent on social media and are spending even longer hours on social networks, a marketing firm and a social media management platform said citing the results on their Digital 2021 study.

We Are Social and Hootsuite said Filipinos spent an average of 4 hours and 15 minutes each day on social media. This was a 22-minute jump from the country’s Digital 2020 average of 3 hours and 53 minutes, the companies said.
