Meta’s new AI Research SuperCluster (RSC) is a metaverse and AI beast — 16,000 GPUs, 16TB/sec training data, 175PB bulk storage.
Time crystals. Microwaves. Diamonds. What do these three disparate things have in common?
Quantum computing. Unlike traditional computers that use bits, quantum computers use qubits to encode information as zeros or ones, or both at the same time. Coupled with a cocktail of forces from quantum physics, these refrigerator-sized machines can process a whole lot of information — but they’re far from flawless. Just like our regular computers, we need to have the right programming languages to properly compute on quantum computers.
Programming quantum computers requires awareness of something called “entanglement,” a computational multiplier for qubits of sorts, which translates to a lot of power. When two qubits are entangled, actions on one qubit can change the value of the other, even when they are physically separated, giving rise to Einstein’s characterization of “spooky action at a distance.” But that potency is equal parts a source of weakness. When programming, discarding one qubit without being mindful of its entanglement with another qubit can destroy the data stored in the other, jeopardizing the correctness of the program.
New findings from the Curiosity Rover’s samples have given scientists another look at distinct carbon signatures found on Mars.
NASA’s Curiosity Rover continues to send back new information about the Red Planet on a frequent basis. The latest discovery brings news of an interesting carbon signature that we didn’t expect to see on Mars. Following analyzations of rock samples returned by the rover, NASA announced that several of the samples are rich in a carbon type that we see on Earth, too. The signature, NASA claims, is most often associated with biological processes, which could give more credence to the possibility of life on Mars.

The ultimate goal, still years away, is to generate power the way the sun generates heat, by smooshing hydrogen atoms so close to each other that they combine into helium, which releases torrents of energy.
WATCH: Is alluring but elusive fusion energy possible in our lifetime?
A team of more than 100 scientists published the results of four experiments that achieved what is known as a burning plasma in Wednesday’s journal Nature. With those results, along with preliminary results announced last August from follow-up experiments, scientists say they are on the threshold of an even bigger advance: ignition. That’s when the fuel can continue to “burn” on its own and produce more energy than what’s needed to spark the initial reaction.
The US officials were left stunned when a Financial Times report revealed that Beijing had tested a nuclear-capable hypersonic missile in August last year. The test demonstrated that China has now garnered the ability to strike any point of earth in no time and that too without letting the target know about any such imminent attack. This bold portrayal of the hypersonic program had dumbstruck the US, whose own hypersonic program runs far behind that of China.
Top Chinese scientist loaded with crucial data defects to the US
However, what has now come as a blessing in disguise for America is the defection of a top Chinese scientist to the West. A report published by Daily Express revealed that a senior rocket technician, connected to the state-owned Aviation Industry Corp of China, recently defected to the US with the help of the UK’s top intelligence agency.
A team mapping radio waves in the Universe has discovered something unusual that releases a giant burst of energy three times an hour, and it’s unlike anything astronomers have seen before. The team who discovered it think it could be a neutron star or a white dwarf—collapsed cores of stars—wi…

Electric bicycle sales have been on a skyward trajectory since early in the pandemic, and new numbers show they are selling more units than electric cars and plug-in hybrids combined.
Those figures recently released by the Light Electric Vehicle Association trade group help bolster the case for personal electric vehicles as alternatives to larger cars and trucks.
According to data released by the LEVA, the US saw nearly 790,000 electric bike imports in 2021. That marks a 70% increase from the 463,000 imports in 2020.
Iron that rusts in water theoretically shouldn’t corrode in contact with an “inert” supercritical fluid of carbon dioxide. But it does.
The reason has eluded materials scientists to now, but a team at Rice University has a theory that could contribute to new strategies to protect iron from the environment.
Materials theorist Boris Yakobson and his colleagues at Rice’s George R. Brown School of Engineering found through atom-level simulations that iron itself plays a role in its own corrosion when exposed to supercritical CO2 (sCO2) and trace amounts of water by promoting the formation of reactive species in the fluid that come back to attack it.
According to our current Cosmological models, the Universe began with a Big Bang roughly 13.8 billion years ago. During the earliest periods, the Universe was permeated by an opaque cloud of hot plasma, preventing atoms from forming. About 380,000 years later, the Universe cooled to a temperature of about-270 °C (−454 °F), which converted much of the energy generated by the Big Bang into light. This afterglow is now visible to astronomers as the Cosmic Microwave Background (CMB), first observed during the 1960s.
One peculiar characteristic about the CMB that attracted a lot of attention was the tiny fluctuations in temperature, which could provide information about the early Universe. In particular, there is a rather large spot in the CMB that is cooler than the surrounding afterglow, known as the CMB Cold Spot. After decades of studying the CMB’s temperature fluctuations, a team of scientists recently confirmed the existence of the largest cold spots in the CMB afterglow – the Eridanus Supervoid – might be the explanation for the CMB Cold Spot that astronomers have been looking for!

Xenobots are living micro-robots, built from cells, designed and programmed by a computer (an evolutionary algorithm) and have been demonstrated to date in the laboratory to move towards a target, pick up a payload, heal themselves after being cut, and reproduce via a process called kinematic self-replication.
