MS treatment a step closer after drug shown to repair nerve coating:

A clinical trial of the cancer drug bexarotene showed that it repaired the protective myelin sheaths that MS destroys. The loss of myelin causes a range of neurological problems including balance, vision and muscle disorders, and ultimately, disability.

While bexarotene cannot be used as a treatment, because the side-effects are too serious, doctors behind the trial said the results showed "remyelination" was possible in humans, suggesting other drugs or drug combinations will halt MS.

[...] MS arises when the immune system mistakenly attacks the fatty myelin coating that wraps around nerves in the brain and spinal cord. Without the lipid-rich substance, signals travel more slowly along nerves, are disrupted, or fail to get through at all. About 100,000 people in the UK live with the condition.

Funded by the MS Society, bexarotene was assessed in a phase 2a trial that used brain scans to monitor changes to damaged neurons in patients with relapsing MS. This is an early stage of the condition that precedes secondary progressive disease, where neurons die off and cause permanent disability.

The drug had some serious side-effects, from thyroid disease to raised levels of fats in the blood, which can lead to dangerous inflammation of the pancreas. But brain scans revealed that neurons had regrown their myelin sheaths, a finding confirmed by tests that showed signals sent from the retina to the visual cortex at the back of the brain had quickened. "That can only be achieved through remyelination," said Coles.

Feds Hit with Successful Cyberattack, Data Stolen:

A federal agency has suffered a successful espionage-related cyberattack that led to a backdoor and multistage malware being dropped on its network.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an alert on Thursday, not naming the agency but providing technical details of the attack. Hackers, it said, gained initial access by using employees' legitimate Microsoft Office 365 log-in credentials to sign onto an agency computer remotely.

"The cyber-threat actor had valid access credentials for multiple users' Microsoft Office 365 (O365) accounts and domain administrator accounts," according to CISA. "First, the threat actor logged into a user's O365 account from Internet Protocol (IP) address 91.219.236[.]166 and then browsed pages on a SharePoint site and downloaded a file. The cyber-threat actor connected multiple times by Transmission Control Protocol (TCP) from IP address 185.86.151[.]223 to the victim organization's virtual private network (VPN) server."

As for how the attackers managed to get their hands on the credentials in the first place, CISA's investigation turned up no definitive answer – however, it speculated that it could have been a result of a vulnerability exploit that it said has been rampant across government networks.

"It is possible the cyber-actor obtained the credentials from an unpatched agency VPN server by exploiting a known vulnerability—CVE-2019-11510—in Pulse Secure," according to the alert. "CVE-2019-11510...allows the remote, unauthenticated retrieval of files, including passwords. CISA has observed wide exploitation of CVE-2019-11510 across the federal government."

Check out the rest of the story for additional details on the attack.

Someone leaked a large amount of sourcecode that may or may not be the complete source code to Windows XP, NT, CE and a few DOS versions. Microsoft won't confirm or deny if it's the actual code.

https://www.bleepingcomputer.com/news/microsoft/the-windows-xp-source-code-was-allegedly-leaked-online/

The source code for Windows XP SP1 and other versions of the operating system was allegedly leaked online today.

The leaker claims to have spent the last two months compiling a collection of leaked Microsoft source code. This 43GB collection was then released today as a torrent on the 4chan forum.

Co-founder of Netscape (formerly Mosaic Communications Corporation) and of Mozilla.org, Jamie Zawinski, has some brief comments about the current situation with Mozilla and its browser.

Back to Mozilla -- in my humble but correct opinion, Mozilla should be doing two things and two things only:

  1. Building THE reference implementation web browser, and
  2. Being a jugular-snapping attack dog on standards committees.
  3. There is no 3.

And they just completely threw in the towel on standards when they grabbed their ankles and allowed W3C to add DRM. At this point, I assume Mozilla's voice on the standards committees has all the world-trembling gravitas of "EFF writes amicus brief."

By the way, one dynamic that the cited article missed is that a huge part of the reason for Google's "investment" in Mozilla was not just to drive search traffic -- it was antitrust insurance. Mozilla continuing to exist made Chrome not be the only remaining web browser, and that kept certain wolves at bay.

Google has decided that they don't need to buy antitrust insurance any more. Wonder why.

Jamie is responding to the summary of the current situation with Mozilla outlined by software engineer Cal Paterson who points out that Firefox usage is down 85% despite Mozilla's top exec pay having gone up 400%.

One of the most popular and most intuitive ways to evaluate an NGO is to judge how much of their spending is on their programme of works (or "mission") and how much is on other things, like administration and fundraising. If you give money to a charity for feeding people in the third world you hope that most of the money you give them goes on food - and not, for example, on company cars for head office staff.

Mozilla looks bad when considered in this light. Fully 30% of all expenditure goes on administration. Charity Navigator, an organisation that measures NGO effectiveness, would give them zero out of ten on the relevant metric. For context, to achieve 5/10 on that measure Mozilla admin would need to be under 25% of spending and, for 10/10, under 15%.

Young physicist 'squares the numbers' on time travel:

Paradox-free time travel is theoretically possible, according to the mathematical modelling of a prodigious University of Queensland undergraduate student.

Fourth-year Bachelor of Advanced Science (Honours) student Germain Tobar has been investigating the possibility of time travel, under the supervision of UQ physicist Dr Fabio Costa.

"Classical dynamics says if you know the state of a system at a particular time, this can tell us the entire history of the system," Mr Tobar said.

[...] "For example, if I know the current position and velocity of an object falling under the force of gravity, I can calculate where it will be at any time.

"However, Einstein's theory of general relativity predicts the existence of time loops or time travel -- where an event can be both in the past and future of itself -- theoretically turning the study of dynamics on its head."

[...] "I wondered: "is time travel mathematically possible?"

Mr Tobar and Dr Costa say they have found a way to "square the numbers" and Dr Costa said the calculations could have fascinating consequences for science.

"The maths checks out -- and the results are the stuff of science fiction," Dr Costa said.

[...] "Try as you might to create a paradox, the events will always adjust themselves, to avoid any inconsistency.

"The range of mathematical processes we discovered show that time travel with free will is logically possible in our universe without any paradox."

Australia Has Venomous Snakes, Spiders, And... Trees:

From snakes and spiders to jellyfish and cone snails, Australia has no shortage of venomous animals. As new research published in Science Advances shows, Australia even harbors venomous plants belonging to the Dendrocnide genus, namely Dendrocnide excelsa and Dendrocnide moroide, both of which are known as "gympie-gympie" in the local indigenous Gubbi Gubbi language.

[...] Dendrocnide plants are "notorious for producing [an] excruciatingly painful sting, which unlike those of their European and North American relatives can cause symptoms that last for days or weeks," Irina Vetter, a co-author of the study, explained in a press release. Similar to other nettles, the stinging tree "is covered in needle-like appendages called trichomes that are around five millimetres in length," she said. They look like fine hairs but "actually act like hypodermic needles that inject toxins when they make contact with skin," said Vetter, an associate professor at the University of Queensland.

[...] In the state of Queensland, it is not uncommon to find warning signs along forest tracks, alerting unwary visitors to the presence of Dendrocnide species and the potency of their sting. This signage is justified given that D. moroides has been implicated in hospitalization of two individuals requiring intensive care for 36 hours who suffered from acute pain that reportedly did not respond to morphine and ongoing symptoms lasting months. This long-lasting pain is also typical of other Dendrocnide species stings, with episodic pain typically subsiding over several weeks, although [painful tingling and prickling sensations] may persist longer.

[...] As the new research shows, this toxin makes permanent alterations to the sodium channels in sensory neurons. Sodium channels are a membrane protein that play a critical role in the formation of pain, which they do through the excitation of neurons. In tests, gympietides was shown to activate the sensory neurons of mice and then prevent them from shutting back down. So this venom—in addition to generating the pain signals—interrupts the mechanism responsible for stopping those signals. That is, in a word, nasty, and it explains why pain sometimes lasts so long after the encounter with the tree.

New 3D printing tech produces smaller-than-ever soft gel objects:

If higher-energy/shorter-wavelength electron beams or X-rays were used instead of ultraviolet or visible light, it would be possible to create items with finer structural detail – this is because it's possible to more tightly focus the beams of those types of radiation. Additionally, no light-sensitive molecules would be required, as the beams could work directly on the polymer chains.

Unfortunately, though, the scanning electron microscopes or X-ray microscopes required to produce the beams must be operated in a vacuum. If the water/polymer mixture were to be placed in such a vacuum, it would evaporate before forming into a gel.

Led by Dr. Andrei Kolmakov, scientists at America's National Institute of Standards and Technology have developed a work-around. By placing an ultra-thin sheet of silicon nitride over the liquid chamber, they protected the solution within from the required vacuum, while still allowing electron beams and X-rays to penetrate through.

The researchers were therefore able to create gels containing structures as small as 100 nanometers in width, which is about one one-thousandth the width of a human hair. Once the system is refined further, it is hoped that it will be possible to print items as small as 50 nanometers – about the size of a small virus.

The approach is mainly thought to find application in medical implants and nanotechnology.

Russia offers its untested COVID-19 vaccine for free to UN officials:

On Tuesday, Russian President Vladimir Putin offered UN staff free doses of the country's COVID-19 vaccine, Sputnik V[*], which has not completed clinical trials for efficacy and has not been thoroughly vetted for safety.

Still, Putin suggested that his offer was prompted by the desire to give the people what they want: "Some colleagues from the UN have asked about this, and we will not remain indifferent to them," he said during a speech Tuesday at this year's (virtual) General Assembly.

Putin made headlines last month after announcing that Russia has granted regulatory approval for the (limited) use of Sputnik V, the first country in the world to do so. He even boasted that one of his daughters had received her first dose of the vaccine.

But public health experts were quickly skeptical of the move, seeing it as merely a political stunt to give the appearance that Russia was "winning" the race to develop a vaccine against the pandemic coronavirus, SARS-CoV-2. At the time, the vaccine had only been tested in two small clinical trials, involving just 76 people total—and the data from those small trials had not yet been released.

[...] Sputnik V has now moved into larger trials with tens of thousands of people. These will test whether the vaccine is safe in a larger number of people and actually protects against infection from SARS-CoV-2. But any clear results are months away.

Sputnik (n.):

"artificial satellite," extended from the name of the one launched by the Soviet Union Oct. 4, 1957, from Russian sputnik "satellite," literally "traveling companion" (in this use short for sputnik zemlyi, "traveling companion of the Earth")

Nikola stock plunges 26% after fraud claims complicate hydrogen plans:

Shares of hydrogen truck startup Nikola plunged 26 percent on Wednesday after The Wall Street Journal reported that the company was struggling to find partners to build a planned network of hydrogen fueling stations. Nikola's stock closed at $21.15 on Wednesday, a decline of 57 percent from the $50 peak reached on September 8

[...] Nikola now concedes that the truck never worked and that a promotional video of the truck was made by rolling it down a hill.

Nikola argued that this was old news because Nikola is no longer marketing the Nikola One and has a working prototype of the Nikola Two. But the revelations threw the company into chaos and forced Milton to resign on Sunday.

Intel Launches 10nm Atom Embedded CPUs: Elkhart Lake Now Available

The embedded and edge markets for Intel have always been hidden away within its IoT business, however at the Investor Meeting last year it was highlighted as one of Intel's key growth areas. The requirements for businesses to enable automation and control, as well as apply machine learning or computer vision, have increased as new optimized algorithms and use cases enter the market, and this is the question that the new 10nm Atom Embedded CPUs are set to answer.

The new processors built with Tremont Atom cores will come as three series of processors: Pentium, Celeron, and Atom x6000E. These are all built with the same silicon die, offering up to four Atom cores with a 3.0 GHz turbo frequency, up to 850 MHz of Gen11 graphics (up to 32 EUs, three 4K60 displays), in TDPs ranging from 4.5 W to 12 W. All processors will support up to LPDDR4X-4267 or DDR4-3200. In-band ECC support is split - the Atom x6000E parts have it, but the Pentium and Celerons do not.

Some of the lineup will include a single ARM Cortex-M7 companion core:

According to Intel, the Atom x6000E family is its first product line to specifically target Internet of Things applications. This is not entirely true, considering that Atom SoCs such as Bay Trail E3800 and Apollo Lake E3900 have targeted IoT duty since the IoT term was invented. IoT was also the main focus of Intel's discontinued line of super low-power Quark processors.

Nevertheless, Intel has added a host of embedded-focused features starting with an Intel Programmable Services Engine (Intel PSE) built around a real-time Arm Cortex-M7 companion core. Intel PSE hosts new functions like remote, network proxy, embedded controller, and sensor hub. The Cortex-M7 is designed to run the open source, Intel-derived Zephyr RTOS.

Ancient Persians were making "20th-century" chromium steel 900 years ago:

One manuscript in particular grabbed their attention. Titled al-Jamahir fi Marifah al-Jawahir, which translates to "A Compendium to Know the Gems", the manuscript was written in the 10th or 11th century CE by the polymath Abu-Rayhan Biruni. Crucially, it contained the only known recipe for forging steel in high-temperature crucibles. The problem is, it can be difficult to follow a thousand-year-old recipe.

"The process of identification can be quite long and complicated and this is for several reasons," says Marcos Martinon-Torres, last author of the study. "Firstly, the language and the terms used to record technological processes or materials may not be used anymore, or their meaning and attribution may be different from those used in the modern science. Additionally, writing was restricted to social elites, rather than the individual that actually carried out the craft, which may have led to errors or omissions in the text."

One ingredient, referred to as "rusakhtaj," puzzled the archaeologists. Eventually they identified it as the ore mineral chromite, which can be used to make chromium crucible steel. Importantly, this was backed up by the discovery of traces of chromite and chromium in artifacts from the Chahak site.

Mixing chromium into steel to make tool steel or stainless steel was thought to be a 19th-20th century invention.

Arm Announces Neoverse V1 & N2 Infrastructure CPUs: +50% IPC, SVE Server Cores

Amazon's Graviton2 64-core Neoverse N1 server chip is the first of what should become a wider range of designs that will be driving the Arm server ecosystem forward and actively assaulting the infrastructure CPU market share that's currently dominated by the x86 players such as Intel and AMD.

[...] Today, we're ready to take the next step towards the next generation of the Neoverse platform, not only revealing the CPU microarchitecture previously known as Zeus, but a whole new product category that goes beyond the Neoverse N-series: Introducing the new Neoverse V-series and the Neoverse V1 (Zeus), as well as a new roadmap insertion in the form of the Neoverse N2 (Perseus).

[...] In terms of generational performance uplift, it's akin to Arm throwing down the gauntlet to the competition, achieving a ground-breaking +50[sic, % obvs] IPC boost compared to Neoverse N1 that we're seeing in silicon today. The performance uplift potential here is tremendous, as this is merely a same-process ISO-frequency upgrade, and actual products based on the V1 will also in all likelihood also see additional performance gains thanks to increased frequencies through process node advancements.

If we take the conservatively clocked Graviton2 with its 2.5GHz N1 cores as a baseline, a theoretical 3GHz V1 chip would represent an 80% uplift in per-core single-threaded performance. Not only would such a performance uptick vastly exceed any current x86 competition in the server space in terms of per-core performance, it would be enough to match the current best high-performance desktop chips from AMD and Intel today (Though we have to remember it'll compete against next-gen Zen3 Milan and Sapphire Rapids products).

[...] Alongside the Neoverse V1 platform, we've seen a roadmap insertion that previously wasn't there. The Perseus design will become the Neoverse N2, and will be the effective product-positioning successor to the N1. This new CPU IP represents a 40% IPC uplift compared to the N1, however still maintains the same design philosophy of maximising performance within the lowest power and smallest area.

Neoverse V1 is basically the server-oriented equivalent of the Cortex-X1 core, where performance is prioritized at the cost of less power efficiency and a greater die area (more cache, etc.). Neoverse N2 is more like (an unannounced successor of) Cortex-A78.

New Atlas:

The MoonRanger project is being led by William "Red" Whittaker, director of the CMU's Field Robotics Center. This is the third lunar research mission awarded to Whittaker by NASA since June of this year.

The new rover will be about the size of a suitcase and weigh roughly 24 lb (11 kg), though it will be very fast as rovers go and enjoy a high degree of autonomy as it makes detailed 3D maps of the lunar terrain. Because the MoonRanger is too small to send radio signals directly to Earth it will gather data independently and then upload it to the Astrobotic lander, which will deliver the rover to the surface. The lander will then relay the data to mission control.

California bans new internal combustion engines, starting in 2035:

On Wednesday, California Governor Gavin Newsom signed an executive order requiring that all new passenger cars and trucks sold in the state from 2035 be zero-emissions vehicles. Additionally, all drayage trucks—the ones that move containers around at places like the Port of Los Angeles—must also go emissions free by this date, as well as off-road vehicles and equipment. Medium- and heavy-duty vehicles get an extra decade to comply, but by 2045 these too must ditch internal combustion engines.

Although this is the first such ICE ban in the United States, Governor Newsom is following in the footsteps of policymakers in Europe, China, and elsewhere. In 2016, Paris, Madrid, Athens, and Mexico City announced bans on new diesel vehicles from 2025. The same year, Germany's Bundesrat voted to outlaw new ICE vehicles from 2030, although this was not a binding resolution.
