FTX founder Sam Bankman-Fried was arrested in the Bahamas at the behest of US prosecutors on Monday, the day before he was due to testify before Congress about the abrupt failure last month of one of the world’s largest cryptocurrency exchanges.

Solar cell technology is a seen as a key pillar in our transition to cleaner forms of energy, but within this field there is all kinds of room for experimentation. Solar cells that are thin and flexible hold unique promise in the area, as they could be applied to all kinds of irregular, curvy or otherwise unsuitable surfaces. Thinner than a human hair, a new lightweight solar cell from MIT scientists continues to push the envelope in this space.
The MIT team behind the technology sought to build on its previous advances in material science, which in 2016 culminated in ultra-thin solar cells light enough to sit atop a soap bubble without breaking it. As is the case with other thin, light and flexible solar cells we’ve looked at over the years, this pointed to all kinds of possibilities, from paper-based electronics to lightweight wearables that harvest energy throughout your day.
Despite the potential, the team still had some problems to solve, with the fabrication technique for the solar cells requiring vacuum chambers and expensive vapor deposition methods. In order to scale the technology up, the scientists have now turned to ink-based printable materials to streamline the process.
“The ARRW team successfully designed and tested an air-launched hypersonic missile in five years,” Brig. Gen. Jason Bartolomei, program executive officer for the Air Force’s armament directorate. “I am immensely proud of the tenacity and dedication this team has shown to provide a vital capability to our warfighter.”
Hypersonic weapons can travel at speeds greater than Mach 5 and maneuver mid-flight, making them much harder to track and shoot down than conventional ballistic missiles and capable of penetrating defenses. Russia and China have invested heavily in developing their own hypersonic weapons, and the U.S. military has faced pressure, including from lawmakers, to show more progress on its own hypersonic capabilities.
The successful test of the operational ARRW prototype continues a series of successful tests for the program in 2022, marking a turnaround from a disappointing 2021 that left the effort in trouble.
Huntington’s disease (HD) is a neurological disorder that causes progressive loss of movement, coordination and cognitive function. It is caused by a mutation in a single gene called huntingtin (HTT). More than 200,000 people worldwide live with the genetic condition, approximately 30,000 in the United States. More than a quarter of a million Americans are at risk of inheriting HD from an affected parent. There is no cure.
But in a new study, published December 12, 2022 in Nature Neuroscience, researchers at University of California San Diego School of Medicine, with colleagues elsewhere, describe using RNA-targeting CRISPR/Cas13D technology to develop a new therapeutic strategy that specifically eliminates toxic RNA that causes HD.
CRISPR is known as a genome-editing tool that allows scientists to add, remove or alter genetic material at specific locations in the genome. It is based on a naturally occurring immune defense system used by bacteria. However, current strategies run the risk of off-target edits at unintended sites that may cause permanent and inheritable chromosomal insertions or genome alterations. Because of this, significant efforts have focused on identifying CRISPR systems that target RNA directly without altering the genome.
An international research team led by Dr. Ana Guadaño at the Alberto Sols Biomedical Research Institute (IIBM, a combined CSIC-UAM center) and involving the Complutense University of Madrid (UCM), used CRISPR gene editing techniques to incorporate into mice a mutation of the MCT8 protein responsible for transporting thyroid hormones to the interior of the cell.
Patients with mutations in this protein suffer from Allan-Herndon-Dudley syndrome, a rare disease that takes the form of serious neurological alterations, in which each patient may reveal a different mutation of MCT8.
This study, published in Neurobiology of Disease, describes the first avatar model for the disease—in other words, the first animal model with the same genetic alteration as various patients.

Germany says China is operating two illegal ‘police stations’ on its territory. These set-ups don’t have a fixed office, and are run by private individuals from the Chinese diaspora. The aim is to collect information on Chinese dissidents and citizens in exile and pass that on to Beijing.
Its a pattern that’s come to light across the world. An earlier report by Madrid based NGO Safeguard Defenders claimed there were more than a hundred such ‘police stations’ in at least 53 countries. Most exist illegally and aim to monitor, coerce and in some instances repatriate, those Beijing considers criminal or anti-China.

Ispace Inc. is a private Japanese company developing robotic landers and rovers for missions to the Moon. It aims to compete for both transportation and exploration mission contracts from space agencies and private industry. If successful, these spacecraft and the accompanying vehicles could enable clients to discover, map, and use the natural resources on Earth’s nearest neighbour.
In addition to its headquarters in Tokyo, the company has offices in the United States and Luxembourg, employing around 200 people. Although founded in 2010, its team of engineers had earlier competed in the Google Lunar X Prize.
Following more than a decade of research and development, ispace yesterday launched Hakuto-R Mission 1 – delivered into space on a partially reusable Falcon 9 Block 5 rocket. The spacecraft will now perform orbital manoeuvres, taking it as far as 1.5 million km (932,000 miles) from Earth, before arriving at the Moon sometime in April 2023.
Summary: Researchers engineered cells containing customized adhesion molecules that bind to specific cell partners in predictable ways to form complex multicellular entities. The discovery is a major step toward building new tissue and organs.

Researchers at UC San Francisco (UCSF) have engineered molecules that act like “cellular glue,” allowing them to direct in precise fashion how cells bond with each other. The discovery represents a major step toward building tissues and organs, a long-sought goal of regenerative medicine.
Christopher Nolan revealed to Total Film magazine that he recreated the first nuclear weapon detonation without CGI effects as part of the production for his new movie “Oppenehimer.” The film stars longtime Nolan collaborator Cillian Murphy as J. Robert Oppenheimer, a leading figure of the Manhattan Project and the creation the atomic bomb during World War II. Nolan has always favored practical effects over VFX (he even blew up a real Boeing 747 for “Tenet”), so it’s no surprise he went the practical route when it came time to film a nuclear weapon explosion.
“I think recreating the Trinity test [the first nuclear weapon detonation, in New Mexico] without the use of computer graphics was a huge challenge to take on,” Nolan said. “Andrew Jackson — my visual effects supervisor, I got him on board early on — was looking at how we could do a lot of the visual elements of the film practically, from representing quantum dynamics and quantum physics to the Trinity test itself, to recreating, with my team, Los Alamos up on a mesa in New Mexico in extraordinary weather, a lot of which was needed for the film, in terms of the very harsh conditions out there — there were huge practical challenges.”
