A team of researchers have built what they claim to be the first living robots. The “xenobots,” they say, can move, pick up objects, and even heal themselves after being cut.
The team is hoping the biological machines could one day be used to clean up microplastics in the ocean or even deliver drugs inside the human body, The Guardian reports.
To build the robots, the team used living cells from frog embryos and assembled them into primitive beings.
A research group at TU Wien has developed a terahertz radiation source that is both efficient and creates a broad spectrum, generating different wavelengths from the entire terahertz range. Both aspects are said to have broken previously held records.

Astronauts make a lot of sacrifices when they venture off of Earth.
Besides the dangers of space travel and time away from family, microgravity comes with a whole new set of rules that dictates many facets of everyday life.
Taiwan has been the world’s hardware hub for decades, so the shift toward AI makes the most of the existing inexpensive engineering talent. A refocus on AI, however, reduces reliance on hardware, which can easily be made somewhere else, such as China, at lower costs. Multinational tech companies have already shown interest in tapping Taiwan’s talent in software, including AI.
To move things along further, the government of Hsinchu County, near Taipei, will open a 126,000-square-meter (about 1.3 million square feet) AI business park near one of Taiwan’s major all-purpose high-tech zones and two top universities.
“[The park] will not just help [promote] industry-academia cooperation, but also let AI-oriented startups and companies have a demo space to verify AI product services,” says Shirley Tsai, a research manager with IDC Taiwan’s enterprise solution group. “It will be helpful as well to attract the companies who are interested in the AI field and then accelerating the AI ecosystem.”
DirecTV has been granted permission by the US Federal Communications Commission (FCC) to send a damaged communications satellite in danger of exploding into an emergency disposal trajectory. The Boeing-built Spaceway-1 direct-broadcast satellite suffered a “major anomaly” last month that caused severe thermal damage to its batteries and must now be moved to an orbit where it will not pose a hazard to other spacecraft.
Orbiting space debris is a major and growing hazard and there has been a great deal of effort in recent years to both clean up dead satellites and to minimize the production of more debris. This not only includes the building of tougher spacecraft that won’t shed bits and pieces but also making sure that damaged satellites are properly disposed of before they become a threat.
According to documents filed by DirecTV with the FCC, the 13,400-lb (6,080-kg) Spaceway-1, which is in a geosynchronous orbit 35,800 km (22,200 mi) above the Earth’s equator, was damaged by an unspecified event in December 2019. Telemetry from the satellite was examined by Boeing engineers who concluded that the batteries on the 702-model satellite had suffered significant and irreversible damage.
MOSCOW – Russia’s next-generation long-range radar technology has been able to detect a group of 6 fifth-generation F-35 multirole fighter jets near the Iranian border. This was achieved by a radar that has a specific mode of operation which uses the ionosphere when scanning airspace.
Missile and air defense radars control airspace around the Russian Federation over distances of up to several thousand kilometers. This was noted by Russian Foreign Minister Sergei Lavrov, who said that long-range air defense radars detected 6 fifth-generation F-35 multi-purpose fighters near Iranian airspace just hours after a missile attack on US military bases in Iraq.
According to the head of Russian Ministry of Foreign Affairs, “at that moment, at least six F-35 fighters were detected near the Iranian border. This information needs further confirmation, however, it indicates the seriousness of the situation which has further increased tensions in the region,” RG, a Russian web portal, stated.
WASHINGTON, D.C. – Although hypersonic weapons might seem like relative newcomers, known advantages of these weapons are both self-evident and multi-faceted as they can be fired from much greater stand-off ranges while having vastly increased ability to defeat, circumvent or simply destroy enemy air and ballistic missile defenses.
USAF Research Laboratory is working round-the-clock on hypersonic weapons designed to come in the next 10–15 years, in order to “expand USAF’s mission options” in the next decades, as an increasingly contested airspace is emerging, limiting US strike capabilities.
The Pentagon has been aggressively pushing for hypersonic weapons development, especially after Russian advances in this field have left the US trailing behind. Given the implications associated with firing weapons able to travel at over five-times the speed of sound, a number of programs have been underway (reportedly, there are up to 8 US hypersonic programs currently underway).
“Think what we can do if we teach a quantum computer to do statistical mechanics,” posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy’s Brookhaven National Laboratory.
At the time, McGuigan was reflecting on Ludwig Boltzmann and how the renowned physicist had to vigorously defend his theories of statistical mechanics. Boltzmann, who proffered his ideas about how atomic properties determine physical properties of matter in the late 19th century, had one extraordinarily huge hurdle: atoms were not even proven to exist at the time. Fatigue and discouragement stemming from his peers not accepting his views on atoms and physics forever haunted Boltzmann.
Today, Boltzmann’s factor, which calculates the probability that a system of particles can be found in a specific energy state relative to zero energy, is widely used in physics. For example, Boltzmann’s factor is used to perform calculations on the world’s largest supercomputers to study the behavior of atoms, molecules, and the quark “soup” discovered using facilities such as the Relativistic Heavy Ion Collider located at Brookhaven Lab and the Large Hadron Collider at CERN.
The age of Quantum AI is upon us. AI needs processing power that current computers can’t provide but quantum computers could pick up the slack.
In 1946 the Electronic Numerical Integrator and Computer, or the ENIAC, was introduced. The world’s first commercial computer was intended to be used by the military to project the trajectory of missiles, doing in a few seconds what it would otherwise take a human mathematician about three days. It’s 20,000 vacuum tubes (the glowing glass light bulb-like predecessors to the transistor) connected by 500,000 hand soldered wires were a marvel of human ingenuity and technology.
Imagine if it were possible to go back to the developers and users of that early marvel and make the case that in 70 years there would be ten billion computers worldwide and half of the world’s population would be walking around with computers 100,000,000 times as powerful as the ENIAC in their pants’ pockets.
You’d have been considered a lunatic!
