NASA Astronaut Moon Lander Plans Expand Beyond SpaceX Starship:

As NASA makes strides to return humans to the lunar surface under Artemis, the agency announced plans Wednesday to create additional opportunities for commercial companies to develop an astronaut Moon lander.

Under this new approach, NASA is asking American companies to propose lander concepts capable of ferrying astronauts between lunar orbit and the lunar surface for missions beyond Artemis III, which will land the first astronauts on the Moon in more than 50 years.

Built and operated according to NASA's long-term requirements at the Moon, new landers will have the capability to dock to a lunar orbiting space station known as Gateway, increase crew capacity, and transport more science and technology to the surface.

"Under Artemis, NASA will carry out a series of groundbreaking missions on and around the Moon to prepare for the next giant leap for humanity: a crewed mission to Mars," said NASA Administrator Bill Nelson. "Competition is critical to our success on the lunar surface and beyond, ensuring we have the capability to carry out a cadence of missions over the next decade. Thank you to the Biden Administration and Congress for their support of this new astronaut lander opportunity, which will ultimately strengthen and increase flexibility for Artemis."

Social engineering attacks to dominate Web3, the metaverse:

Researchers predict that a surge in social engineering attacks will dominate web3 and the metaverse.

Web3 is the term coined for what could become the next face of the internet. The web has shifted from pages containing content to the growth of social media, and now, the concept of a decentralized internet is being discussed under the Web3 banner.

Part of this transformation could include the 'metaverse' -- a 3D environment and virtual world for facilitating social connections, whether personal or for work. Your ID in the metaverse may also end up linked to cryptocurrency wallets, Non Fungible Tokens (NFTs), and various smart contracts.

As technology vendors work on these concepts, cybersecurity researchers from Cisco Talos have offered their perspective on the potential threats Web3, and the metaverse will face.

How access to satellite images shifts the view of war:

Media coverage of the war in Ukraine, which started almost a month ago, has included, arguably to an unprecedented extent, content shared via social media. This has included satellite photos that document troop movements and shocking damage to cities.

In recent days, pictures snapped by satellites in orbit have captured images which appear to show destroyed Russian helicopters, extensive damage to a shopping centre and residential districts in Mariupol, and a civilian tanker vessel on fire in the Black Sea.

Privately-owned companies that launch and operate their own satellites - such as Planet and Maxar - have distributed many satellite images of the conflict zone.

The proliferation of these images means members of the public and military analysts alike can try to gauge the situation on the ground in Ukraine and the progress of Russia's invading armed forces from thousands of miles away.

[...] So, what's changed? While government and intelligence agency satellites gather classified, secret information, commercial firms have long been able to sell their own, unclassified, imagery. And now, this material is being made easily accessible online.

Brain implants allow fully paralysed man to communicate:

A fully paralysed man suffering from amyotrophic lateral sclerosis (ALS) can now communicate with his family after receiving microchip implants in his brain.

It is the first time a completely locked-in person – someone who is conscious and cognitively able but fully paralysed – was able to communicate in full sentences, according to a study published in the journal Nature Communications this week.

"People have really doubted whether this was even feasible," Mariska Vansteensel, a researcher at the University Medical Center Utrecht who was not involved in the study, told Science.org.

The unidentified German man, 36, was diagnosed with ALS, a rare progressive nervous system disease that leads to the loss of muscle control, in 2015.

New pumpkin shaped nucleus radiates protons with record setting rate:

The new isotope was found among the products of fusion of ⁵⁸Ni beam particles and ⁹⁶Ru target atoms, and it was identified in the detector setup of the MARA separator. ¹⁴⁹Lu was found to decay into ¹⁴⁸Yb via spontaneous proton emission, which is a rare nuclear decay mode. Decay properties of ¹⁴⁹Lu were measured to be exceptional; It has the highest decay energy and the shortest directly measured half-life of any ground-state proton emitter known to date.

Observation of the swift decay was made possible by modern digital signal handling that allows "traces" to be recorded, see attached figure for a few examples. Additionally, it was found via comparison to theoretical calculations that it is the most oblate deformed ("pumpkin shaped") proton emitter.

This is the first instance when the models of proton emission are tested against such a strong oblate deformation. These observations will help to develop the theory of proton emission as well as the atomic mass models for the most exotic isotopes, both models are needed to understand the origin of the elements. The results of this study have been published as the Editors' Suggestion in Physical Review Letters.

Humans have given wild animals their diseases nearly 100 times, researchers find:

In a study published March 22 in Ecology Letters, the authors describe nearly one hundred different cases where diseases have undergone "spillback" from humans back into wild animals, much like how SARS-CoV-2 has been able to spread in mink farms, zoo lions and tigers, and wild white-tailed deer.

"There has understandably been an enormous amount of interest in human-to-wild animal pathogen transmission in light of the pandemic," says Gregory Albery, Ph.D., a postdoctoral fellow in the Department of Biology at Georgetown University and the study's senior author. "To help guide conversations and policy surrounding spillback of our pathogens in the future, we went digging through the literature to see how the process has manifested in the past."

In their new study, Albery and colleagues found that almost half of the incidents identified occurred in captive settings like zoos, where veterinarians keep a close eye on animals' health and are more likely to notice when a virus makes the jump. Additionally, more than half of cases they found were human-to-primate transmission, an unsurprising result both because pathogens find it easier to jump between closely-related hosts, and because wild populations of endangered great apes are so carefully monitored.

[...] Disease spillback has recently attracted substantial attention due to the spread of SARS-CoV-2, the virus that causes COVID-19, in wild white-tailed deer in the United States and Canada. Some data suggest that deer have given the virus back to humans in at least one case, and many scientists have expressed broader concerns that new animal reservoirs might give the virus extra chances to evolve new variants.

Tiny, cheap solution for quantum-secure encryption - The Source - Washington University in St. Louis:

It's fairly reasonable to assume that an encrypted email can't be seen by prying eyes. That's because in order to break through most of the encryption systems we use on a day-to-day basis, unless you are the intended recipient, you'd need the answer to a mathematical problem that's nearly impossible for a computer to solve in a reasonable amount of time.

Nearly impossible for modern-day computers, at least.

"If quantum computing becomes a reality, however, some of those problems are not hard anymore," said Shantanu Chakrabartty, the Clifford W. Murphy Professor and vice dean for research and graduate education in the Preston M. Green Department of Electrical & Systems Engineering at the McKelvey School of Engineering.

[...] Chakrabartty's lab at Washington University in St. Louis proposes a security system that is not only resistant to quantum attacks, but is also inexpensive, more convenient, and scalable without the need for fancy new equipment.

[...] The new protocol for Symmetric Key Distribution, which Chakrabartty and Mustafizur Rahman, a PhD student in Chakrabartty's lab and first author on the research paper, refer to as SPoTKD, doesn't require lasers or satellites or miles of new cable. It relies on tiny microchips embedded with even tinier clocks that run without batteries.

AI suggested 40,000 new possible chemical weapons in just six hours:

It took less than six hours for drug-developing AI to invent 40,000 potentially lethal molecules. Researchers put AI normally used to search for helpful drugs into a kind of "bad actor" mode to show how easily it could be abused at a biological arms control conference.

All the researchers had to do was tweak their methodology to seek out, rather than weed out toxicity. The AI came up with tens of thousands of new substances, some of which are similar to VX, the most potent nerve agent ever developed. Shaken, they published their findings this month in the journal Nature Machine Intelligence.

The paper had us at The Verge a little shook, too. So, to figure out how worried we should be, The Verge spoke with Fabio Urbina, lead author of the paper. He's also a senior scientist at Collaborations Pharmaceuticals, Inc., a company that focuses on finding drug treatments for rare diseases.

Linux Mint Announces Latest Debian Based OS:

Linux Mint has announced the latest release of its Debian based operating system Linux Mint Debian Edition (LMDE), codename "Elsie" is based upon the latest Debian "Bullseye" release and is an alternative to the mainstream Ubuntu based Linux Mint.

LMDE, or Linux Mint Debian Edition, is a backup version of Mint designed to preserve the work put into, and user experience of, Linux Mint should Ubuntu ever disappear to the great software graveyard in the sky. As Ubuntu is itself built on Debian architecture, to the uninitiated the difference is hard to discern. But under the hood there are notable software changes inline with the source operating system's philosophy. Following a successful beta release at the end of February, the time has come for a full version.

LMDE 5, codenamed Elsie, is made using the same Debian 11 Bullseye that Raspberry Pi OS made such a difficult upgrade to last year (as more recently and successfully did Peppermint OS). This, however, seems to be a much more fortunate project than Raspberry Pi's, displaying the same Cinnamon desktop as the Ubuntu-based version of Mint, but with none of the Snap containerised software packages used by Canonical's operating system. Instead, it uses the Flatpak application manager, along with a native Firefox app straight from Mozilla. Being a Debian based OS, Linux Mint also comes with the APT (Advanced Packaging Tool) to manage software installation.

The system requirements are modest, with just 2GB of RAM (4GB for a 'comfortable experience') and 20GB of disk space required. A screen resolution of 1024 x 768 is recommended, but on coarser displays there's a workaround involving Alt+dragging windows to get them on the screen.

Stephen Wilhite, creator of the GIF, has died

NPC-131072 and canopic jugwrite:

From The Verge

Stephen Wilhite, one of the lead inventors of the GIF, died last week from COVID at the age of 74, according to his wife, Kathaleen, who spoke to The Verge. He was surrounded by family when he passed. His obituary page notes that "even with all his accomplishments, he remained a very humble, kind, and good man."

Stephen Wilhite worked on GIF, or Graphics Interchange Format, which is now used for reactions, messages, and jokes, while employed at CompuServe in the 1980s. He retired around the early 2000s and spent his time traveling, camping, and building model trains in his basement.

Live updates: Russians destroy Chernobyl laboratory:

LVIV, Ukraine -- Russian military forces have destroyed a new laboratory at the Chernobyl nuclear power plant that among other things works to improve management of radioactive waste, the Ukrainian state agency responsible for the Chernobyl exclusion zone said Tuesday.

The Russian military seized the decommissioned plant at the beginning of the war. The exclusion zone is the contaminated area around the plant, site of the world's worst nuclear meltdown in 1986.

[...] The laboratory contained "highly active samples and samples of radionuclides that are now in the hands of the enemy, which we hope will harm itself and not the civilized world," the agency said in its statement.

Radionuclides are unstable atoms of chemical elements that release radiation.

Reporting bias makes homeopathy trials look like homeopathy works:

One of the more productive ways that the methods of science can be used is to look at the scientific process itself. A "meta-science" study (like a recent one published on brain scans) can help tell us when research approaches aren't producing reliable data and can potentially show what we might need to change to get those approaches to work.

Now, someone has applied a bit of meta-science to an area of research where we shouldn't expect to see improvements: homeopathy. A group of Austrian researchers looked into why a reasonable fraction of the clinical trials on homeopathy produce positive results. The biggest factor, the researchers found, is that the trials that show homeopathy is ineffective are less likely to get published.

There are plenty of ways to test potential treatments, but over the years, problems have been identified in almost all of them. That's left the double-blind, randomized clinical trial as the most trusted method of getting rid of some of the biases that make other approaches less reliable. But even in double-blind trials, problems can creep in. There's always a bias toward publishing positive results—ones where the treatments have an effect.

First Microsoft, then Okta: New ransomware gang posts data from both:

A relatively new entrant to the ransomware scene has made two startling claims in recent days by posting images that appear to show proprietary data the group says it stole from Microsoft and Okta, a single sign-on provider with 15,000 customers.

The Lapsus$ group, which first appeared three months ago, said Monday evening on its Telegram channel that it gained privileged access to some of Okta's proprietary data. The claim, if true, could be serious because Okta allows employees to use a single account to log in to multiple services belonging to their employer.

In late January 2022, Okta detected an attempt to compromise the account of a third-party customer support engineer working for one of our subprocessors. The matter was investigated and contained by the subprocessor. We believe the screenshots shared online are connected to this January event. Based on our investigation to date, there is no evidence of ongoing malicious activity beyond the activity detected in January.

[...] Over the weekend, the same Telegram channel posted images to support a claim Lapsus$ made that it breached Microsoft systems. The Telegram post was later removed—but not before security researcher Dominic Alvieri documented the hack on Twitter.

Russian Government Mulls Chinese Foundries, State Aid to Evade US Sanctions:

The Russian Federation government is considering adding chip designers Baikal Electronics and MCST to the list of 'backbone enterprises.' The status will provide Baikal and MSCT with numerous benefits, including subsidies. State aid might help these companies to transition the production of their chips from Taiwan to China. Meanwhile, it is unclear whether fabs like SMIC and Hua Hong are interested in making chips for Russian companies and risk additional sanctions.

"Such a move could also be aimed at transferring the production of Russian processors from the Taiwanese TSMC, which abandoned their production due to sanctions, to Chinese factories," a report by CNews reads.

Amid the global chip deficit, prominent Chinese foundries like SMIC and Hua Hong have landed large orders from existing and new clients. Officially, SMIC has been operating at over 100% capacity for several quarters now, so it is unclear whether it can even make chips for Baikal and MCST. Another question is whether those companies can legally produce those processors.

[...] While many media outlets highlight ASML, the world's largest supplier of lithography equipment, as the key maker of semiconductor production tools, there are a half-dozen U.S.-based companies (Applied Materials, KLA, Lam Research, etc.) that build fab equipment without which fabs cannot function. As a result, virtually all foundries in the world need to obtain an export license from the U.S. government if they want to make chips for companies like Huawei, Phytium, Sunway, or essentially all Russian chipmakers.

License applications to produce chips for the said companies are undertaken with a presumption of denial. So given the current attitude towards Russia, it is unlikely that SMIC and Hua Hong can actually help Russia to save its two major developers of CPUs. Furthermore, it is unclear from where Baikal could get contemporary Arm licenses as the U.K. has also imposed sanctions against the Russian high-tech industry.

https://arstechnica.com/tech-policy/2022/03/apple-employee-conspired-with-suppliers-stole-parts-in-10m-fraud-doj-says/

Under CEO Tim Cook's watchful eye, Apple has become famous for its tightly managed supply chain. Yet even the most finely tuned machines run into problems from time to time. The case of Dhirendra Prasad appears to be one of those times.
[...]
The alleged scam worked something like this: Prasad would receive a list of parts and services that Apple needed. He would then request quotes from vendors, negotiate with them, and choose which ones would get the business. From this position of power, Prasad could put his thumb on the scale, and he apparently gave Hansen's and Baker's companies a leg up in exchange for something on the side.
[...]
Prasad's alleged scheme appears to have ramped up as it went on. In 2017, Prasad reported that his income was $1,215,000, the government alleges. "In fact, as defendant knew and believed, defendant had taxable income for 2017 that was greater than the amount reported on the tax return."

US attorneys believe that Prasad attempted to launder that money by purchasing five properties, most of them in California's Central Valley, and stashing funds in various investment accounts, 529 college savings plans, and a retirement annuity. The seized assets are worth about $5 million, the government estimates.
