Tor Forum: a new discussion platform for the Tor Community:

Communicating and finding help online is crucial to building a solid community. After many years of using emails, mailing lists, blog comments, and IRC to help Tor users, we believe that time has come to improve our discussion channels.

Today, we're happy to announce a new discussion and user support platform: the Tor Forum.

The new forum is powered by Discourse: a modern, friendly, and free and open source software. The forum posts are publicly readable, and you don't need to log in to navigate and access the content. It's also possible to install the Discourse App on your mobile device and receive notifications. For users who like the traditional mailing list format, Discourse features email integration. The new forum is compatible and works with Tor Browser (security slider level set 'Safer').

Currently, the Tor Forum is fully hosted by Discourse, and because they do not support onion services yet, it won't have an onion site soon. That is also why the domain is torproject.net, because of our system security policy on using *.torproject.org only for sites we host in our own infrastructure.

In the last few years, the Tor Project has improved internal tools and platforms to make it easy to contribute to Tor software development and to participate in our community. For example, we revamped our websites, moved from Trac to GitLab, connected our chat channels on Matrix, and now we're launching the Tor Forum.

We invite the Tor community to join the Tor Forum and contribute with us! Moderation policy: Don't be a jerk. Be awesome instead.

Malware downloaded from PyPI 41,000 times was surprisingly stealthy:

PyPI—the open source repository that both large and small organizations use to download code libraries—was hosting 11 malicious packages that were downloaded more than 41,000 times in one of the latest reported such incidents threatening the software supply chain.

JFrog, a security firm that monitors PyPI and other repositories for malware, said the packages are notable for the lengths its developers took to camouflage their malicious code from network detection. Those lengths include a novel mechanism that uses what's known as a reverse shell to proxy communications with control servers through the Fastly content distribution network. Another technique is DNS tunneling, something that JFrog said it had never seen before in malicious software uploaded to PyPI.

"Package managers are a growing and powerful vector for the unintentional installation of malicious code, and as we discovered with these 11 new PyPI packages, attackers are getting more sophisticated in their approach, Shachar Menashe, senior director of JFrog research, wrote in an email. "The advanced evasion techniques used in these malware packages, such as novel exfiltration or even DNS tunneling (the first we've seen in packages uploaded to PyPI) signal a disturbing trend that attackers are becoming stealthier in their attacks on open source software."

The researchers said that PyPI quickly removed all malicious packages once JFrog reported them.

Arthur T Knackerbracket has processed the following story:

At least 25 people in two states were likely poisoned by toxic batches of the "Re2al ," including five children who suffered acute liver failure and one person who died.

The toxic water made headlines earlier this year when health investigators initially linked alkalized water sold by Nevada-based water company Real Water to severe illnesses in five children in Clark County, Nevada. But the new report from the CDC offers the most complete look at the identified cases and illnesses.

The saga began in November and December of 2020, when the five children—ranging in age from seven months to five years—became severely ill with acute liver failure after drinking the water. They were hospitalized and later transferred to a children's hospital for a potential liver transplant—though they all subsequently recovered without a transplant. Local health officials investigating the unusual cluster found that family members had also been sickened. The only common link between the cases was the alkalized water, which Real Water claimed was a healthier alternative to tap water.

In mid-March, the Food and Drug Administration contacted Real Water about the cases and urged the company to recall their water, which was sold in multiple states, including Nevada, California, Utah, and Arizona. Real Water agreed to issue the recall. However, by the end of the month, the FDA reported that retailers were still selling the potentially dangerous water, and the regulator tried to warn consumers directly. By then, Nevada health officials had linked the water to six additional cases, including three more children, bringing the total to 11.

Now, according to the new report, the tally has increased to 25: 18 probable cases and four suspected cases in Nevada, as well as three probable cases in California.

All 21 probable cases ended up hospitalized, and 18 required intensive care. One woman in her 60s with underlying medical conditions died of complications from her liver inflammation.

Box86 + Box64 Updated For Running Linux x86/x86_64 Programs On Other Architectures

Box86 as the open-source project to run Linux x86 binaries on other CPU architectures like ARM is out with a new feature release along with the accompanying Box64 project for x86_64 treatment. With today's Box86 update is even expanded Vulkan support now good enough for handling DXVK.

Box86 aims to run Linux x86 binaries on other CPU architectures with better performance than QEMU or other forms of virtualization. With Box86 also comes the ability to utilize OpenGL acceleration and even running some Steam / Wine games when taking some additional steps. Though in order for Box86 to work out, the operating system does need a working 32-bit subsystem/libraries. Besides ARM, Box86 could prove important with the growing interest in RISC-V as well as there having been interest from the (Open)POWER side too. Meanwhile Box64 has also been updated as the adjoining project providing similar treatment for running x86 64-bit binaries on other architectures.

box86 v0.2.4 and box64 v0.1.6.

MIT Physicists Use Fundamental Atomic Property To Turn Matter Invisible:

A new study confirms that as atoms are chilled and squeezed to extremes, their ability to scatter light is suppressed.

An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli exclusion principle, and it explains the shell structure of atoms, the diversity of the periodic table of elements, and the stability of the material universe.

Now, MIT physicists have observed the Pauli exclusion principle, or Pauli blocking, in a completely new way: They've found that the effect can suppress how a cloud of atoms scatters light.

Normally, when photons of light penetrate a cloud of atoms, the photons and atoms can ping off each other like billiard balls, scattering light in every direction to radiate light, and thus make the cloud visible. However, the MIT team observed that when atoms are supercooled and ultrasqueezed, the Pauli effect kicks in and the particles effectively have less room to scatter light. The photons instead stream through, without being scattered.

In their experiments, the physicists observed this effect in a cloud of lithium atoms. As they were made colder and more dense, the atoms scattered less light and became progressively dimmer. The researchers suspect that if they could push the conditions further, to temperatures of absolute zero, the cloud would become entirely invisible.

The team's results, reported today in Science, represent the first observation of Pauli blocking's effect on light-scattering by atoms. This effect was predicted 30 years ago but not observed until now.

This paper is from 2017, however, I found it interesting and thought our community would also find this worthy of discussion ...

Have you ever wondered if there is a correlation between a computer's energy consumption and the choice of programming languages? Well, a group Portuguese university researchers did and set out to quantify it. Their 2017 research paper entitled Energy Efficiency across Programming Languages / How Do Energy, Time, and Memory Relate? may have escaped your attention, as it did ours.

The team used a collection of ten standard algorithms from the Computer Language Benchmarks Game project (formerly known as The Great Computer Language Shootout) as the basis for their evaluations.

Last year they updated the functional language results, and all the setups, benchmarks, and collected data can be found here. Check out the paper for more details. Have your choice of programming language ever been influenced by energy consumption?

In the early morning hours of June 24, 2021, half of the 12-story Surfside Florida luxury condominium, Champlain Towers South, came crashing to the ground, killing 98 occupants.

In a recent public update, the NIST detailed the lengthy work needed to uncover the causes of this collapse.

This includes building design, construction, modification, and deterioration analysis, evidence preservation, remote sensing analysis using data collected with tools such as LIDAR during recovery, material tests on recovered evidence, a geotechnical analysis of the surrounding soil and geologic conditions, as well as detailed structural and failure analysis using computer modeling.

Additionally, they will interview people with historic knowledge of construction in south Florida, and continue to accept information from the public that could shed additional light on this tragedy.

Although answers from NIST's investigation will not be forthcoming for a number of years, many individuals unrelated to the NIST have combed through publicly available information to find possible causes.

While precise triggers leading to the collapse may never be known, most public evidence, as this video demonstrates, points to two key factors: Badly neglected and deteriorated pool deck concrete slab that lead to a pool deck collapse, and resulting damage to three key building support columns that lead to the building collapse minutes later.

A timeline based on public witness accounts, details the dramatic events of that morning.

In an interesting twist, this USA Today article digs deep in to possible drug related money laundering and corruption surrounding the building's construction.

AP News reports a lawsuit that was just filed alleges previous construction next door contributed to the collapse.

Most of the media has focused on the lack of "answers" from the NIST and other organizations. Youtuber Jeff Ostroff has compiled an informative explanation of who NIST is, why the NIST is investigating, and why this takes so long.

100,000 people died from drug overdoses in the US in one year, a record:

During a one-year period from April 2020 to April 2021, more than 100,000 people died from a drug overdose in the US, according to provisional data from the National Vital Statistics System, a government network for sharing public-health data. The number is a record for the US and means about 274 people died each day.

In December 2020, the US Centers for Disease Control and Prevention sounded the alarm on an increase in overdose deaths -- more than 93,000 in 2020. Factors compounding the existing overdose epidemic may include the financial and emotional burdens of the coronavirus pandemic, along with COVID-era problems in getting health care and mental health services.

Fatal overdoses continue to be driven by opioids, particularly the extremely potent fentanyl. Overdose deaths involving fentanyl or other synthetic opioids increased 12-fold from 2013 to 2019, the CDC reported.

Fentanyl, which is legal if it's prescribed to treat severe pain, is up to 50 times more potent than heroin and 100 times stronger than morphine, the CDC says. Nonprescription fentanyl is illegal, which means it doesn't undergo any testing or safety regulations. Heroin, cocaine and other drugs are often laced with fentanyl, so people who overdose on fentanyl may not even know they consumed it or may have underestimated how much fentanyl was in the other drug.

The US Drug Enforcement Agency says that without laboratory testing, there's no way to know the amount of fentanyl in a pill or drug. Test strips people can use to check whether a drug contains fentanyl can be found at some public health clinics, including syringe services programs. But they don't reveal the amount of fentanyl in the drug; they only show its presence.

Scientist advances prospect of regeneration in humans:

Without macrophages, which are part of the immune system, regeneration did not take place. Instead of regenerating a limb, the axolotl formed a scar at the site of the injury, which acted as a barrier to regeneration, just as it would in a mammal such as a mouse or human. In terms of regenerative capability, Godwin had turned the salamander into a mammal. In a follow-up 2017 study, he found the same to be true in heart tissue.

Now, in a study that builds on his earlier research, Godwin has identified the origin of pro-regenerative macrophages in the axolotl as the liver. By providing science with a place to look for pro-regenerative macrophages in humans -- the liver, rather than the bone marrow, which is the source of most human macrophages -- the finding paves the way for regenerative medicine therapies in humans.

Although the prospect of regrowing a human limb may be unrealistic in the short term due to a limb's complexity, regenerative medicine therapies could potentially be employed in the shorter term in the treatment of the many diseases in which scarring plays a pathological role, including heart, lung and kidney disease, as well as in the treatment of scarring itself -- for instance, in the case of burn victims.

"In our earlier research, we found that scar-free healing hinges on a single cell type, the macrophage," Godwin said. "This finding means we have a way in. If axolotls can regenerate by having a single cell type as their guardian, then maybe we can achieve scar-free healing in humans by populating our bodies with an equivalent guardian cell type, which would open up the opportunity for regeneration."

The paper on Godwin's research, entitled "Identification of the Adult Hematopoietic Liver As the Primary Reservoir for the Recruitment of Pro-regenerative Macrophages Required for Salamander Limb Regeneration," was recently published in the journal Frontiers in Cell and Developmental Biology.

[...] If the regenerative process at the site of an injury can be compared to a party -- an analogy Godwin often uses -- his research has revealed the category of guest who attends and, now, where the guests come from and how and when they get there. The next step will be to nail down their specific identities, or as he puts it, the "flavors" of macrophages required for regeneration, and how they interact with other guests.

That research will revolve around the study of scarring, or fibrosis, which in adult mammals blocks regeneration through its effect on tissue function and integrity.

Although it remains to be seen if achieving scar-free healing in mammals will allow regeneration to proceed -- other processes may also be involved -- Godwin believes that may be the case. Because mammals already possess the machinery for regeneration -- young mice can regenerate, as can human newborns -- mammalian regeneration may simply be a matter of removing the barrier posed by scarring.

NASA's Perseverance captures challenging flight by Mars helicopter:

Ingenuity is currently prepping for its 16th flight, scheduled to take place no earlier than Saturday, Nov. 20, but the 160.5-second Flight 13 stands out as one of Ingenuity's most complicated. It involved flying into varied terrain within the "Séítah" geological feature and taking images of an outcrop from multiple angles for the rover team. Acquired from an altitude of 26 feet (8 meters), the images complement those collected during Flight 12, providing valuable insight for Perseverance scientists and rover drivers.

Captured by the rover's two-camera Mastcam-Z, one video clip of Flight 13 shows a majority of the 4-pound (1.8-kilogram) rotorcraft's flight profile. The other provides a closeup of takeoff and landing, which was acquired as part of a science observation intended to measure the dust plumes generated by the helicopter.

"The value of Mastcam-Z really shines through with these video clips," said Justin Maki, deputy principal investigator for the Mastcam-Z instrument at NASA's Jet Propulsion Laboratory in Southern California. "Even at 300 meters [328 yards] away, we get a magnificent closeup of takeoff and landing through Mastcam-Z's 'right eye." And while the helicopter is little more than a speck in the wide view taken through the 'left eye," it gives viewers a good feel for the size of the environment that Ingenuity is exploring."

During takeoff, Ingenuity kicks up a small plume of dust that the right camera, or "eye," captures moving to the right of the helicopter during ascent. After its initial climb to planned maximum altitude of 26 feet (8 meters), the helicopter performs a small pirouette to line up its color camera for scouting. Then Ingenuity pitches over, allowing the rotors' thrust to begin moving it horizontally through the thin Martian air before moving offscreen. Later, the rotorcraft returns and lands in the vicinity of where it took off. The team targeted a different landing spot—about 39 feet (12 meters) from takeoff—to avoid a ripple of sand it landed on at the completion of Flight 12.

NASA tracked wild 'earthgrazer' meteor fireball for 186 miles through the air:

Some meteors are fancier than others. Lucky skywatchers in the southeastern US were treated to a fantastic fireball on Tuesday night. Data from NASA shows it was quite a whopper, traveling 186 miles (300 kilometers) through the air.

NASA's Marshall Space Flight Center in Alabama tweeted images of the fireball as captured by NASA meteor cameras. A map shows the trajectory stretched across Georgia and into Alabama before ending above the town of Lutts, Tennessee.

NASA Meteor Watch, a group that brings together the work of meteor experts and amateur meteor watchers, gave an update on the fireball on Facebook on Wednesday. "Last night's fireball over Georgia and Alabama was what we call an earthgrazer, in which the meteor's trajectory is so shallow it just skims across the upper atmosphere for a long distance."

The group described the event as "a rare meteor for those fortunate enough to see it." A video from a meteor camera at the Tellus Science Museum in Cartersville, Georgia, shows part of the fireball's path.

We're currently in a good fireball-watching season as the Taurid meteor shower is underway. The Taurids are caused by dust and debris from an ancient comet. When those little bits hit the atmosphere, they can burn up into bright "shooting stars."

Microsoft is no longer bringing x64 emulation to Windows 10 on ARM

Last December, Microsoft announced that it would bring x64 emulation to Windows 10 on ARM, a feature missing from the fledgling OS. Windows 10 on ARM already supported x86 emulation but making sure you have a 32-bit installer is not ideal. Initially, Microsoft brought x64 emulation to the Windows Insider Program, although you need a preview version of the Qualcomm Adreno graphics driver for some ARM machines that supported Windows 10 ARM.

Since then, Microsoft has released Windows 11, including an ARM version. For some reason, the company has now decided to quietly drop any intentions of integrating x64 emulation within Windows 10 on ARM. Inexplicably, it only confirmed this change in a Windows Blogs post where most people would miss it.

But there are many other electric vehicle (EV) racing events popping-up across the country that are showcasing and championing important advances in EV technology.

Formula E has been around for years, but a flood of newer EV racing events have lately zoomed into view.

Others include the Extreme E race series, which launched earlier this year. In it, electric sports utility vehicles (SUVs) compete in a series of off-road events. And in 2022, SuperCharge will bring EV racing to city streets around the world.

Battery life, safety, and weight are three dimensions that EV racers are focused on to give them a competitive edge.

But mostly battery life -- Ed. (yeah, yeah, that belongs in the comments - shut up!).

Anyway, plenty of variants available - including 2-wheeled ones. That might be what powers your sit-on lawnmower in a few years.

Paralysed mice walk again after a single injection

A new therapy, developed by researchers in the USA, has successfully reversed paralysis and repaired severe spinal cord injuries in mice. The animals regained the ability to walk only four weeks after a single injection of the treatment.

"Our research aims to find a therapy that can prevent individuals from becoming paralysed after major trauma or disease," said Prof Samuel I Stupp of Northwestern University, who led the study. "For decades, this has remained a major challenge for scientists because our body's central nervous system, which includes the brain and spinal cord, does not have any significant capacity to repair itself after injury or after the onset of a degenerative disease."

When the therapy is injected, the liquid immediately forms a network of nanofibres matching the structure around the spinal cord. The difficulty then is in communicating with the body's cells.

[...] "The key innovation in our research, which has never been done before, is to control the collective motion of more than 100,000 molecules within our nanofibres," he said. "By making the molecules move, 'dance' or even leap temporarily out of these structures, known as supramolecular polymers, they are able to connect more effectively with [cellular] receptors."
