An anonymous reader shared this report from SFGate: Late last year, tales of tech workers paying $700 a month for tiny "bed pods" in downtown San Francisco went viral. The story provided a perfect distillation of SF's wild (and wildly expensive) housing market — and inspired schadenfreude when the city deemed the situation illegal. But the provocative living situation wasn't an anomaly, according to a city official.

"We've definitely seen an uptick of these 'pod'-type complaints," Kelly Wong, a planner with San Francisco's code enforcement and zoning and compliance team, told SFGATE... Wong stressed that it's not that San Francisco is inherently against bed pod-type arrangements, but that the city is responsible for making sure these spaces are safe and legally zoned.

So Brownstone Shared Housing is still renting one bed pod location — but not accepting new tenants — after citations for failing to get proper permits and having a lock on the front door that required a key to exit.

And SFGate also spoke to Alex Akel, general manager of Olive Rooms, which opened up a co-living and co-working space in SoMa earlier this year (and also faced "a flurry of complaints.") "Unfortunately, we had complaints from neighbors because of foot traffic and noise, and since then we cut the number of people to fit the ordinance by the city," Akel wrote. Olive Rooms describes its space as targeted at "tech founders from Central Asia, giving them opportunities to get involved in the current AI boom." Akel added that its residents are "bringing new energy to SF," but that the program "will not accept new residents before we clarify the status with the city."

In April, the city also received a complaint about a group called Let's Be Buds, which rents out 14 pods in a loft on Divisadero Street that start at $575 per month for an upper bunk.

While this recent burst of complaints is new, bed pods in San Francisco have been catching flak for years... a company called PodShare, which rents — you guessed it — bed pods, squared itself away with the city and has operated in SF since 2019.
Brownstone's CEO told SFGate "A lot of people want to be here for AI, or for school, or different opportunities." He argues that "it's literally impossible without a product like ours," and that their residents had said the option "positively changed the trajectory of their lives."

An anonymous reader shared this report from the New York Times: American officials are trying to increase international pressure on Russia not to deploy an antisatellite nuclear weapon in space, and have obtained information that undermines Moscow's explanation that the device it is developing is for peaceful scientific purposes, a senior State Department official said on Friday...

On Friday, Mallory Stewart, the assistant secretary of state for arms control, said that while the United States had been aware of Russia's pursuit of such a device for years, "only recently have we been able to make a more precise assessment of their progress." Ms. Stewart, speaking at the nonpartisan Center for Strategic and International Studies in Washington, said the orbit the Russian satellite would occupy is in a high-radiation region not used by other satellites, information that undercuts Russia's defense that it is not developing a weapon.

An anonymous reader shared this report from the Washington Post: The heat shield of the Orion spacecraft intended one day to carry astronauts to the moon under NASA's Artemis program suffered unexpected damage in more than 100 places as the spacecraft returned to Earth during an uncrewed test flight in 2022, according to a watchdog report released late Wednesday.

While the capsule withstood the fiery tumult of reentry, when temperatures reached 5,000 degrees Fahrenheit as it plunged through the atmosphere at nearly 25,000 mph, the damage the heat shield suffered was far greater than NASA engineers had expected and more severe than NASA had revealed previously. Photos of the heat shield in the report showed gouges that look like small potholes. "Should the same issue occur on future Artemis missions, it could lead to the loss of the vehicle or crew," the report, by NASA's inspector general, concluded... The IG report provides the most detailed description of the issue to date. It also highlighted other problems with the spacecraft that could create significant challenges for the space agency as it seeks to return humans to the lunar surface for the first time in more than 50 years.

Portions of the heat shield "wore away differently than NASA engineers predicted, cracking and breaking off the spacecraft in fragments that created a trail of debris rather than melting away as designed," according to the report. That, in turn, "could have caused enough structural damage to cause one of Orion's parachutes to fail...." In addition to the heat shield erosion on Orion, which is manufactured by Lockheed Martin, the IG said several bolts on the crew module "experienced an exposed gap that allowed for increased heating to the bolt interior and greater than expected melting and erosion."
Earlier this year, NASA announced the next flight for its moon program — sending a crew of four around the moon — would be delayed, according to the article. The moon-orbiting mission would now occur "no earlier than September 2025, largely because officials wanted to study the heat shield issue further and understand why it eroded as it did."

The article adds that this new report "casts doubt on both NASA's rosy original assessment of the test flight" — as well as the likelihood that a lunar landing will occur by late 2026.

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.

The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator.

Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

The world's highest astronomical site is officially open for business after being in the works for 26 years. Space.com reports: The Japanese University of Tokyo Atacama Observatory, or TAO, which was first conceptualized 26 years ago to study the evolution of galaxies and exoplanets, is perched on top of a tall mountain in the Chilean Andes at 5,640 meters (18,500 feet) above sea level. The facility's altitude surpasses even the Atacama Large Millimeter Array, which is at an elevation of 5,050 meters (16,570 feet).

TAO is located on the summit of Atacama's Cerro Chajnantor mountain, whose name means "place of departure" in the now-extinct Kunza language of the indigenous Likan Antai community. The region's high altitude, sparse atmosphere and perennially arid climate is deadly to humans, but makes an excellent spot for infrared telescopes like TAO as their observational accuracies rely on low moisture levels, which render Earth's atmosphere transparent in infrared wavelengths.

TAO's 6.5-meter telescope consists of two science instruments designed to observe the universe in infrared, which is electromagnetic radiation with a wavelength longer than visible light but shorter than microwaves. One of the instruments, named SWIMS, will image galaxies from the very early universe to understand how they coalesced out of pristine dust and gas, a process whose specifics remain murky despite decades of research. The second, named MIMIZUKU, will aid the overarching science goal by studying primordial disks of dust within which stars and galaxies are known to form, according to the mission plan. Constructing the telescope on the summit of Mt. Chajnantor "was an incredible challenge, not just technically, but politically too," Yuzuru Yoshii, a professor at the University of Tokyo in Japan who spearheaded TAO since 1998, said in a statement. "I have liaised with Indigenous peoples to ensure their rights and views are considered, the Chilean government to secure permission, local universities for technical collaboration, and even the Chilean Health Ministry to make sure people can work at that altitude in a safe manner."

"Thanks to all involved, research I've only ever dreamed about can soon become a reality, and I couldn't be happier," he added.

An anonymous reader quotes a report from The Guardian: Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring. Flares are used by fossil fuel companies when capturing the natural gas would cost more than they can make by selling it. They release carbon dioxide and toxic pollutants when they burn as well as cancer-causing chemicals. Despite the health risks, regulators sometimes prefer flaring to releasing natural gas -- which is 90% methane -- directly into the atmosphere, known as "venting".

The World Bank, alongside the EU and other regulators, have been using satellites for years to find and document gas flares, asking energy companies to find ways of capturing the gas instead of burning or venting it. The bank set up the Zero Routine Flaring 2030 initiative at the Paris climate conference to eradicate unnecessary flaring, and its latest report stated that flaring decreased by 3% globally from 2021 to 2022. But since the initiative, "enclosed combustors" have begun appearing in the same countries that promised to end flaring. Experts say enclosed combustors are functionally the same as flares, except the flame is hidden. Tim Doty, a former regulator at the Texas Commission on Environmental Quality, said: "Enclosed combustors are basically a flare with an internal flare tip that you don't see. Enclosed flaring is still flaring. It's just different infrastructure that they're allowing.

"Enclosed flaring is, in truth, probably less efficient than a typical flare. It's better than venting, but going from a flare to an enclosed flare or a vapor combustor is not an improvement in reducing emissions." The only method of detecting flaring globally is by using satellite-mounted tools called Visible Infrared Imaging Radiometer Suite of detectors (VIIRS), which find flares by comparing heat signatures with bright spots of light visible from space. But when researchers tried to replicate the database, they saw that the satellites were not picking up the enclosed flares. Without the satellite data, countries were forced to rely mostly on self-disclosed reporting from oil and gas companies, researchers said. Environmentalists fear the research community's ability to understand pollution and greenhouse gas emissions from the energy sector could be jeopardized.

Florida Gov. Ron DeSantis signed a bill this week banning and criminalizing the manufacture and sale of lab-grown meat in the state. From a report: The legislation joins similar efforts from three other states -- Alabama, Arizona and Tennessee -- that have also looked to stop the sale of lab-grown meat, which is believed to still be years away from commercial viability. "Florida is fighting back against the global elite's plan to force the world to eat meat grown in a petri dish or bugs to achieve their authoritarian goals," DeSantis said. "We will save our beef."

Lab-grown meat, also known as cultivated meat, has attracted considerable attention in recent years as startups have raised millions of dollars to improve the technology meant to create a climate-friendly alternative to traditional meat sources. Cultivated meat is usually grown in a metal vessel from a sample of animal cells. They multiply in a container called a bioreactor while being fed with water, amino acids, vitamins and lipids -- a process that can be difficult to do at scales large enough to create enough food for commercial sale. Still, some companies have made strides, with two California startups receiving approval from U.S. regulators last year to sell lab-grown chicken. Those companies said Florida's bill stifles innovation in a space that is becoming competitive globally.

China launched an uncrewed lunar mission Friday that aims to bring back samples from the far side of the moon for the first time, in a potentially major step forward for the country's ambitious space program. From a report: The Chang'e-6 probe -- China's most complex robotic lunar mission to date -- blasted off on a Long March-5 rocket from the Wenchang Space Launch Center in south China's Hainan island, where space fans had gathered to watch the historic moment. The country's National Space Administration said the launch was a success. The launch marks the start of a mission that aims to be a key milestone in China's push to become a dominant space power with plans to land astronauts on the moon by 2030 and build a research base on its south pole.

It comes as a growing number of countries, including the United States, eye the strategic and scientific benefits of expanded lunar exploration in an increasingly competitive field. China's planned 53-day mission would see the Chang'e-6 lander touch down in a gaping crater on the moon's far side, which never faces Earth. China became the first and only country to land on the moon's far side during its 2019 Chang'e-4 mission. Any far-side samples retrieved by the Chang'e-6 lander could help scientists peer back into the evolution of the moon and the solar system itself -- and provide important data to advance China's lunar ambitions.

Aria Alamalhodaei reports via TechCrunch: Hubble Network has become the first company in history to establish a Bluetooth connection directly to a satellite -- a critical technology validation for the company, potentially opening the door to connecting millions more devices anywhere in the world. The Seattle-based startup launched its first two satellites to orbit on SpaceX's Transporter-10 ride-share mission in March; since that time, the company confirmed that it has received signals from the onboard 3.5mm Bluetooth chips from over 600 kilometers away.

The sky is truly the limit for space-enabled Bluetooth devices: the startup says its technology can be used in markets including logistics, cattle tracking, smart collars for pets, GPS watches for kids, car inventory, construction sites, and soil temperature monitoring. Haro said the low-hanging fruit is those industries that are desperate for network coverage even once per day, like remote asset monitoring for the oil and gas industry. As the constellation scales, Hubble will turn its attention to sectors that may need more frequent updates, like soil monitoring, to continuous coverage use cases like fall monitoring for the elderly. Once its up and running, a customer would simply need to integrate their devices' chipsets with a piece of firmware to enable connection to Hubble's network.

Satellite operator SES plans to buy fellow satellite operator Intelsat, in a $3.1 billion deal that's expected to close next year. According to Space Magazine, the combined company could help it "compete with SpaceX's huge Starlink broadband network." From the report: SES and Intelsat both operate communications satellites in geostationary orbit, which lies 22,236 miles (35,785 kilometers) above Earth. SES also runs a constellation called O3b in medium Earth orbit, at an altitude of about 5,000 miles (8,000 km). As [SES CEO Adel Al-Saleh] noted, there is increasingly fierce competition for the services provided by these satellites -- for example, from SpaceX's Starlink megaconstellation in low Earth orbit. And other LEO megaconstellations are in the works as well. For instance, Amazon launched the first two prototypes for its planned 3,200-satellite Project Kuiper network this past October.

"By combining our financial strength and world-class team with that of SES, we create a more competitive, growth-oriented solutions provider in an industry going through disruptive change," Intelsat CEO David Wajsgras said in the same statement. "The combined company will be positioned to meet customers' needs around the world and exceed their expectations," he added.

Kaiser Permanente is the latest healthcare giant to report a data breach. Kaiser said 13.4 million current and former insurance members had their patient data shared with third-party advertisers, thanks to an improperly implemented tracking code the company used to see how its members navigated through its websites. Dark Reading reports: The shared data included names, IP addresses, what pages people visited, whether they were actively signed in, and even the search terms they used when visiting the company's online health encyclopedia. Kaiser has reportedly removed the tracking code from its sites, and while the incident wasn't a hacking event, the breach is still concerning from a security perspective, according to Narayana Pappu, CEO at Zendata.

"The presence of third-party trackers belonging to advertisers, and the oversharing of customer information with these trackers, is a pervasive problem in both health tech and government space," he explains. "Once shared, advertisers have used this information to target ads at users for complementary products (based on health data); this has happened multiple times in the past few years, including at Goodrx. Although this does not fit the traditional definition of a data breach, it essentially results in the same outcome -- an entity and the use case the data was not intended for has access to it. There is usually no monitoring/auditing process to identify and prevent the issue."

Richard Speed reports via The Register: NASA's optical communications demonstration has hit 25 Mbps in a test transmitting engineering data back to Earth from 140 million miles (226 million kilometers) away. The payload is riding aboard the Psyche probe, which is headed for an asteroid of the same name. On December 11, when the spacecraft was 19 million miles (30 million kilometers) away, it reached 267 Mbps, which NASA described as "comparable to broadband internet download speeds."

However, as Psyche has continued on its trajectory, the distances have become greater, and the rate at which data can be transmitted and received has tumbled. At 140 million miles, the project's goal was to reach a lofty 1 Mbps. Instead, engineers managed to get 25 Mbps out of the demonstration. Earlier demonstrations tested the technology using preloaded data, such as a cat video. The latest experiment used a copy of engineering data also sent via Psyche's radio transmitter.

"We downlinked about 10 minutes of duplicated spacecraft data during a pass on April 8," said Meera Srinivasan, the project's operations lead at NASA's Jet Propulsion Laboratory (JPL) in Southern California. "Until then, we'd been sending test and diagnostic data in our downlinks from Psyche. This represents a significant milestone for the project by showing how optical communications can interface with a spacecraft's radio frequency comms system." The demonstrator is only along for the ride -- Psyche uses conventional radio technology for its mission. However, the demonstration does point to the potential for higher-bandwidth communications in future projects.

RockDoctor (Slashdot reader #15,477) wants to tell you about a "new" star that will be visible to the naked eye — without a telescope — sometime before September: By "star", I do not mean "comet", "meteorite" or "firefly", but genuine [star] photons arriving here after about 3000 years in flight, causing your eyes to see a bright point on the nighttime sky. When it happens, the star will go from needing-a- telescope-or-good-binoculars-to-see, to being the 50th (or even 30th) brightest star in the sky.

For a week or so. Of course, it could just go full-on supernova, and be visible in daylight for a few weeks, and dominate the night sky for months. But that's unlikely.
Named "T Corona Borealis" (because it's the 20th variable star studied in the constellation "Corona Borealis") it's now visible all night, all year, for about 60% of the world's population (although normally you need binoculars to see it).

But RockDoctor writes that in 2016, "T CrB" (as it is known) has started showing "a similar pattern of changes" to what happened in the late 1930s when it became one of only 10 "recurring nova" known to science: In 2023, the pattern continued and the match of details got better. The star is expected to undergo another "eruption" — becoming one of the brightest few stars in the sky, within the next couple of months. Maybe the next couple of weeks. Maybe the next couple of hours....

Last week, astrophysicist Dr Becky Smethurst posted on the expected event in her monthly "Night Sky News" video blog. If you prefer your information in text not video, the AAVSO (variable star observers) posted a news alert for it's observers a while ago. They also hosted a seminar on the star, and why it's eruption is expected Real Soon Now, which is also on YouTube. A small selection of recent papers on the subject are posted here, which also includes information on how to get the most up-to-date brightness readings (unless you're a HST / JWST / Palomar / Hawai`i / Chile telescope operator). Yes, the "big guns" of astronomy have prepared their "TOO — Target Of Opportunity" plans, and will be dropping normal observations really quickly when the news breaks and slewing TOO the target.

You won't need your eclipse glasses for this. (Dr Becky's video covers where you can send them for re-use.) But you might want to photograph the appropriate part of the sky so you'll notice when the bomb goes off. Bomb? Did I say that the best model for what is happening is a thermonuclear explosion like a H-bomb the size of the Earth detonating? Well, that's the best analogue.
This CNN article includes a nice animation from NASA illustrating the multi-star interaction that's causing the event: The stars in the orbiting pair are close enough to each other that they interact violently. The red giant becomes increasingly unstable over time as it heats up, casting off its outer layers that land as matter on the white dwarf star. The exchange of matter causes the atmosphere of the white dwarf to gradually heat until it experiences a "runaway thermonuclear reaction," resulting in a nova [according to NASA]...

The NASAUniverse account on X, formerly known as Twitter, will provide updates about the outburst and its appearance.
The BBC reiterates the key data points — that "The rare cosmic event is expected to take place sometime before September 2024. When it occurs it will likely be visible to the naked eye. No expensive telescope will be needed to witness this cosmic performance, says NASA."

An anonymous reader shared this report from CNN: Five times the size of Paris. Visible from space. The world's biggest energy plant. Enough electricity to power Switzerland. The scale of the project transforming swathes of barren salt desert on the edge of western India into one of the most important sources of clean energy anywhere on the planet is so overwhelming that the man in charge can't keep up. "I don't even do the math any more," Sagar Adani told CNN in an interview last week.

Adani is executive director of Adani Green Energy Limited (AGEL). He's also the nephew of Gautam Adani, Asia's second richest man, whose $100 billion fortune stems from the Adani Group, India's biggest coal importer and a leading miner of the dirty fuel. Founded in 1988, the conglomerate has businesses in fields ranging from ports and thermal power plants to media and cements. Its clean energy unit AGEL is building the sprawling solar and wind power plant in the western Indian state of Gujarat at a cost of about $20 billion.

It will be the world's biggest renewable park when it is finished in about five years, and should generate enough clean electricity to power 16 million Indian homes... [T]he park will cover more than 200 square miles and be the planet's largest power plant regardless of the energy source, AGEL said.
CNN adds that the company "plans to invest $100 billion into energy transition over the next decade, with 70% of the investments ear-marked for clean energy."

This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair."

"This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year.
After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board."

This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery....

All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer."
SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth."

But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

In September NASA's James Webb Space Telescope investigated an exoplanet 8.6 times as massive as Earth, and "revealed the presence of carbon-bearing molecules including methane and carbon dioxide." Webb's discovery adds to recent studies suggesting that [planet] K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface... The planet's large size — with a radius 2.6 times the radius of Earth — means that the planet's interior likely contains a large mantle of high-pressure ice, like Neptune, but with a thinner hydrogen-rich atmosphere and an ocean surface. Hycean worlds are predicted to have oceans of water. However, it is also possible that the ocean is too hot to be habitable or be liquid.
NASA's announcement included some additional context: K2-18 b orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light-years from Earth in the constellation Leo. Exoplanets such as K2-18 b, which have sizes between those of Earth and Neptune, are unlike anything in our solar system. This lack of equivalent nearby planets means that these 'sub-Neptunes' are poorly understood, and the nature of their atmospheres is a matter of active debate among astronomers. The suggestion that the sub-Neptune K2-18 b could be a Hycean exoplanet is intriguing, as some astronomers believe that these worlds are promising environments to search for evidence for life on exoplanets...

The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b.
Long-time Slashdot reader Baron_Yam noticed some sites resurfacing the news from September this week with more spectacular headlines, like "NASA discovered a planet twice as big as Earth with a gas that is 'only produced by life'" and "Discovery... sparks huge excitement among astronomers.

NASA's announcement? It's early Webb observations "provided a possible detection of a molecule called dimethyl sulfide. On Earth, this is only produced by life." The bulk of the dimethyl sulfide in Earth's atmosphere is emitted from phytoplankton in marine environments.

The inference of dimethyl sulfide is less robust and requires further validation. "Upcoming Webb observations should be able to confirm if dimethyl sulfide is indeed present in the atmosphere of K2-18 b at significant levels," explained Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of the paper announcing these results.

While K2-18 b lies in the habitable zone, and is now known to harbor carbon-bearing molecules, this does not necessarily mean that the planet can support life.
But it's all a validation of the new discoveries being made possible by space telescopes — new and old. "The first insight into the atmospheric properties of this habitable-zone exoplanet came from observations with NASA's Hubble Space Telescope, which prompted further studies..." "This result was only possible because of the extended wavelength range and unprecedented sensitivity of Webb, which enabled robust detection of spectral features with just two transits," said Madhusudhan... "These results are the product of just two observations of K2-18 b, with many more on the way," explained team member Savvas Constantinou of the University of Cambridge. "This means our work here is but an early demonstration of what Webb can observe in habitable-zone exoplanets."

[...] The team now intends to conduct follow-up research with the telescope's MIRI (Mid-Infrared Instrument) spectrograph that they hope will further validate their findings and provide new insights into the environmental conditions on K2-18 b. "Our ultimate goal is the identification of life on a habitable exoplanet, which would transform our understanding of our place in the universe," concluded Madhusudhan. "Our findings are a promising step towards a deeper understanding of Hycean worlds in this quest."

This week Russia vetoed a UN resolution that proposed banning nuclear weapons in space, CNN reports.

But it all happened "amid U.S. intelligence-backed concerns that Moscow is trying to develop a nuclear device capable of destroying satellites." In February, President Joe Biden confirmed the US has intelligence that Russia is developing a nuclear anti-satellite capability. Three sources familiar with the intelligence subsequently told CNN the weapon could destroy satellites by creating a massive energy wave when detonated...

US Ambassador Linda Thomas-Greenfield said Wednesday's vote "marks a real missed opportunity to rebuild much-needed trust in existing arms control obligations." A US and Japan-drafted resolution had received cross-regional support from more than 60 member states. It intended to strengthen and uphold the global non-proliferation regime, including in outer space, and reaffirm the shared goal of maintaining outer space for peaceful purposes. It also called on UN member states not to develop nuclear weapons or other weapons of mass destruction designed to be placed in Earth's orbit....

Experts say this kind of weapon could have the potential to wipe out mega constellations of small satellites, like SpaceX's Starlink, which has been successfully used by Ukraine to counter Russian troops. This would almost certainly be "a last-ditch weapon" for Russia, the US official and other sources said — because it would do the same damage to whatever Russian satellites were also in the area.
The article notes that in March Russian President Vladimir Putin "told officials that space projects, including the setup of a nuclear power unit in space, should be a priority and receive proper financing."

1,000 petabytes.
A million terabytes.
One quintillion bytes (or 1,000,000,000,000,000,000).

That's the amount of storage reported by users of the Ceph storage solution (across more than 3,000 Ceph clusters).

The Ceph Foundation is a "directed fund" of the Linux Foundation, providing a neutral home for Ceph, "the most popular open source storage solution for modern data storage challenges" (offering an architecture that's "highly scalable, resilient, and flexible"). It's a software-defined storage platform, providing object storage, block storage, and file storage built on a common distributed cluster foundation.

And Friday they announced the release of Ceph Squid, "which comes with several performance and space efficiency features along with enhanced protocol support." Ceph has solidified its position as the cornerstone of open source data storage. The release of Ceph Squid represents a significant milestone toward providing scalable, reliable, and flexible storage solutions that meet the ever-evolving demands of digital data storage.

Features of Ceph Squid include improvements to BlueStore [a storage back end specifically designed for managing data on disk for Ceph Object Storage Daemon workloads] to reduce latency and CPU requirements for snapshot intensive workloads. BlueStore now uses RocksDB compression by default for increased average performance and reduced space usage. [And the next-generation Crimson OSD also has improvements in stability and read performance, and "now supports scrub, partial recovery and osdmap trimming."]

Ceph continues to drive the future of storage, and welcomes developers, partners, and technology enthusiasts to get involved.
Ceph Squid also brings enhancements for the CRUSH algorithm [which computes storage locations] to support more flexible and cost effective erasure coding configurations.

Lenovo's latest ThinkPad P1 Gen 7 laptop is set to be the first to use the new LPCAMM2 memory form factor, the successor to SODIMM sticks. From a report: While Lenovo has largely focused on the AI performance of its new laptop, which is equipped with an Intel Core Ultra CPU and Nvidia RTX 3000 Ada GPU, the company also noted that its device was the first in the world to use the LPCAMM2 memory standard. LPCAMM2 uses 64 percent less space than SODIMM and 61 percent less active power, according to Lenovo. This is thanks to it being based on LPDDR5X memory instead of regular DDR5.

Designed specifically for laptops, the LPCAMM2 standard actually has its origins in tech developed by Dell. Simply termed CAMM (Compression Attached Memory Module), it first debuted as a proprietary type of memory in Dell's Precision 7670 in 2022. However, in 2023 the PC giant donated its intellectual property to JEDEC, the organization that standardizes memory technologies. CAMM became LPCAMM2 (Low-Power Compression Attached Memory Module) in September 2023 when JEDEC finally confirmed its specifications. Samsung promptly announced plans to produce LPCAMM2 sticks, and claimed they would have 50 percent more performance and 70 percent more efficiency than their SODIMM-based predecessors. Plus, LPCAMM2 can offer dual-channel memory without requiring a second module.

Today, Framework is the modular repairable laptop company. Tomorrow, it wants to be a consumer electronics company, period. From a report: That's one of the biggest reasons it just raised another $18 million in funding -- it wants to expand beyond the laptop into "additional product categories." Framework CEO Nirav Patel tells me that has always been the plan. The company originally had other viable ideas beyond laptops, too. "We chose to take on the notebook space first," he says, partly because Framework knew it could bootstrap its ambitions by catering to the PC builders and tinkerers and Linux enthusiasts left behind by big OEMs -- and partly because it wanted to go big or go home.

If Framework could succeed in laptops, he thought, it would be able to build almost anything. After five years building laptops, what might Framework add to the portfolio? Patel won't say -- I only get the barest hints, no matter how many different ways I ask. He won't even say if they'll make less or more of a splash than laptops. Framework might choose an "equally difficult" category or might instead try something "a bit smaller and simpler to execute, streamlined now that we have all this infrastructure."
