Over the last couple of years weve seen several iterations of the slow movie player concept, where a film is broken up into individual frames which are displayed on an e-paper display for a few minutes at a time. This turns your favorite movie into a constantly changing piece of long-term art. Unfortunately, due to the relatively high cost of e-paper panels, most of the examples weve seen have only been a few inches across.

Of course, technology tends to get cheaper with time, which has allowed [szantaii] to put together this beautiful 10.3-inch version. With a 1872 1404 Waveshare panel capable of displaying 16 shades of gray and a Raspberry Pi Zero 2 W installed in a commercially purchased frame, the final product looks very professional. It certainly wouldnt look out of place in a well-appointed living room.

Instead of outputting in plastic, this printer builds models that you can eat:

All of the best 3D printers print from some form plastic, either from filament or from resin. But an upcoming printer, Cocoa Press, uses chocolate to create models you can eat. The brainchild of Maker and Battlebots Competitor Ellie Weinstein , who has been working on iterations of the printer since 2014, Cocoa Press will be available for pre-order, starting on April 17th via cocoapress.com (the company is also named Cocoa Press).

[...] In lieu of a roll of filament or a tank full of resin, the Cocoa Press uses 70g cartridges of special chocolate that solidifies at up to 26.67 degrees Celsius (80 degrees Fahrenheit), which the company will sell for $49 for a 10 pack. The cigar-shaped chocolate pieces go into a metal syringe where the entire thing is melted at the same time rather than melting as it passes through the extruder (like a typical FDM printer).

Spatial Commerce Projects is a Shopify lab working to provide concepts, prototypes, and tools to explore the crossroads of spatial computing and commerce.

The graphical output provides a real sense of depth and three-dimensional space using an optical illusion that reacts to the viewers eye position. The eye position is used to render view-dependent images. The computer screen is made to feel like a window into a realistic 3D virtual space where objects beyond the window appear to have depth and objects before the window appear to project out into the space in front of the screen. The resulting experience is like a 3D view into a virtual space. The downside is that the experience only works for one viewer.

Physicists are learning more about the bizarre behavior of strange metals, which operate outside the normal rules of electricity.

Theoretical physicist Yashar Komijani, an assistant professor at the University of Cincinnati, contributed to an international experiment using a strange metal made from an alloy of ytterbium, a rare earth metal. Physicists in a lab in Hyogo, Japan, fired radioactive gamma rays at the strange metal to observe its unusual electrical behavior.

Led by Hisao Kobayashi with the University of Hyogo and RIKEN, the study was published in the journal Science. The experiment revealed unusual fluctuations in the strange metals electrical charge.

Astronomers report the discovery of two new exoplanets orbiting a bright sun-like star about 175 light years away. The newfound alien worlds, designated HIP 104,045 b and HIP 104,045 c, were classified as a Jupiter analog and a super Neptune planet, respectively. The finding was detailed in a paper published March 2 on the pre-print server arXiv.

The radial velocity (RV) method to detect an exoplanet is based on the detection of variations in the velocity of the central star, due to the changing direction of the gravitational pull from an unseen exoplanet as it orbits the star. Thanks to this technique, more than 600 exoplanets have been detected so far.

Now, a team of astronomers led by Thiago Ferreira of the University of So Paulo in Brazil, reports the detection of two new exoplanets using the RV method. They observed a solar-type star HIP 104,045 with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph on the 3.6m telescope of the European Southern Observatory (ESO) in La Silla, Chile. The observations, conducted as part of the Solar Twin Planet Search (STPS) program, resulted in the discovery of two massive extrasolar worlds.

Self-testing is a promising method to infer the physics underlying specific quantum experiments using only collected measurements. While this method can be used to examine bipartite pure entangled states, so far it could only be applied to limited kinds of quantum states involving an arbitrary number of systems.

Researchers at Sorbonne University, ICFO-Institute of Photonic Sciences and Quantinuum recently introduced a framework for the quantum network-assisted self-testing of all pure entangled states of an arbitrary number of systems. Their paper, published in Nature Physics, could inform future research efforts aimed at certifying quantum phenomena.

I was a postdoctoral researcher in Barcelona in 2014 in the group of Antonio Acn when the first author, Ivan upi and I began working on self-testing quantum states together, Matty Hoban, one of the researchers who carried out the study, told Phys.org. That is, certifying that you have systems in particular quantum states without trusting the devices and treating them as black boxes (called the device-independent setting). Part of this work involved exploring different kinds of scenarios of trust.

Quantum processors are computing systems that process information and perform computations by exploiting quantum mechanical phenomena. These systems could significantly outperform conventional processors on certain tasks, both in terms of speed and computational capabilities.

While engineers have developed several promising quantum computing systems over the past decade or so, scaling these systems and ensuring that they can be deployed on a large-scale remains an ongoing challenge. One proposed strategy to increase the scalability of quantum processors entails the creation of modular systems containing multiple smaller quantum modules, which can be individually calibrated and then arranged into a bigger architecture. This, however, would require suitable and effective interconnects (i.e., devices for connecting these smaller modules).

Researchers at the Southern University of Science and Technology, the International Quantum Academy and other institutes in China have recently developed low-loss interconnects for linking the individual modules in modular superconducting quantum processors. These interconnects, introduced in Nature Electronics, are based on pure aluminum cables and on-chip impendence transformers.

Super-resolution microscopy methods are essential for uncovering the structures of cells and the dynamics of molecules. Since researchers overcame the resolution limit of around 250 nanometers (while winning the 2014 Nobel Prize in Chemistry for their efforts), which had long been considered absolute, the methods of microscopy have progressed rapidly.

Now a team led by LMU chemist Prof. Philip Tinnefeld has made a further advance through the combination of various methods, achieving the highest resolution in three-dimensional space and paving the way for a fundamentally new approach for faster imaging of dense molecular structures. The new method permits axial resolution of under 0.3 nanometers.

The researchers combined the so-called pMINFLUX method developed by Tinnefelds team with an approach that utilizes special properties of graphene as an energy acceptor. pMINFLUX is based on the measurement of the fluorescence intensity of molecules excited by laser pulses. The method makes it possible to distinguish their lateral distances with a resolution of just 1 nanometer.

A venerable strategy for approximating a systems ground states has now been extended to accommodate its excited states.

Density-functional theory (DFT) owes its name and utility to its central insight: that a potentials influence on a system of interacting electrons can be expressed in terms of the electrons density. Existing models restrict DFT to ground states and exclude excited states. But now Tim Gould of Griffith University, Australia, and his collaborators have found a way to overcome the restriction [1].

At the heart of DFT are exchange-correlation models, which simplify the treatment of electrons behavior by using certain limiting cases. This simplification allows DFT to simulate ground states of large electronic systems. A generalization of the theory, called ensemble DFT, can cope with excited states, but this theorys more complex exchange-correlation models make large systems computationally intractable. Gould and his collaborators discovered that when the electron density is sufficiently low, these complications vanish and the models for dealing with excited states revert to being as simple as those used for regular DFT. Then, regular DFT suffices. At the other extremewhen electron density is highcomplications are simplified to the point that exact solutions can be obtained.

Another part of that wariness arises because, to date, no one has independently reproduced Dias teams results. This lack of verification was raised by Jorge Hirsch of the University of California, San Diego, in the last talk of the session in which Dias and his team spoke. Hirsch argued that those claiming to have created high-temperature superconducting hydrides suffered from confirmation bias, cherry-picking evidence to support their agenda. (Hirsch has been an outspoken critic of Dias work.) As the last question of the session, Dias asked Hirsch, Could you also have confirmation bias? Maybe, Hirsch replied.

After the session, a few attending researchersall collaborators of Diasspoke with Physics Magazine, telling us that they disagreed with Hirschs cherry-picking conclusion. One of them, Russell Hemley of the University of Illinois Chicago confirmed Pasans claim that they have replicated the 2020 carbonaceous sulfur hydrideas reported in an arXiv paper that the team recently posted [3].

Dias group still needs to more precisely characterize NLHs chemical composition, Pasan said. The samples also appear to consist of two phases, an observation that they need to investigate. Ultimately, they plan to innovate upon this material to create a superconductor at ambient pressure and temperature conditions, a goal that Pasan said he thinks is feasible. But extraordinary claims require extraordinary evidence, and the community has much of the latter still to gather.

Cisco fixed a high-severity DoS vulnerability (CVE-2023-20049) in IOS XR software that impacts several enterprise routers.

Cisco has released security updates to address a high-severity DoS vulnerability, tracked as CVE-2023-20049 (CVSS score of 8.6), in IOS XR software used by several enterprise-grade routers.

The vulnerability resides in the bidirectional forwarding detection (BFD) hardware offload feature of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers, ASR 9902 Compact High-Performance Routers, and ASR 9903 Compact High-Performance Routers.

An unauthenticated, remote attacker can trigger the flaw to cause a line card to reset, resulting in a denial of service (DoS) condition.

An attacker can trigger the CVE-2023-20049 vulnerability by sending a crafted IPv4 BFD packet to a vulnerable device.

This vulnerability is due to the incorrect handling of malformed BFD packets that are received on line cards where the BFD hardware offload feature is enabled. reads the advisory published by the vendor. . A successful exploit could allow the attacker to cause line card exceptions or a hard reset, resulting in loss of traffic over that line card while the line card reloads.

This flaw affects Cisco routers running a vulnerable release of Cisco IOS XR 64-bit Software and have BFD hardware offload enabled for any of the installed line cards:

• ASR 9000 Series Aggregation Services Routers only if they have a Lightspeed or Lightspeed-Plus-based line card installed
• ASR 9902 Compact High-Performance Routers
• ASR 9903 Compact High-Performance Routers

The company pointed out that this vulnerability does not affect the following Cisco products:

• IOS Software
• IOS XE Software
• IOS XR Platforms not listed in the Vulnerable Products section of this advisory

As a workaround, Cisco recommends disabling the BFD hardware offload and creating Infrastructure Access Control lists.

The IT giant addressed the issue with the release of IOS XR versions 7.5.3, 7.6.2, and 7.7.1.

[TRX Lab] has an old Heathkit model IT-1121 curve tracer, and wants to modify it so he can plot the I-V curves of MOSFETs. For the uninitiated, curve tracers are used to determine the precise characteristics of components by measuring the output for a set of specific inputs either voltage or current depending on the device youre testing.

The IT-1121 was introduced in 1973 and supports bipolar and FET transistors of types NPN, PNP, N-channel, and P-channel, along with various other semiconductor devices. But [TRX] wanted to enhance the tester to deal with MOSFETs as well.

The IT-1121 is very flexible, and has selector switches for all the usual polarity and sweep settings Heathkit also sold a model IT-3121 in later years, but this seems to have been the same basic tester. [TRX] found two shortcomings when plotting the I-V curve of MOSFETs. First, there is no way to apply a Vgs threshold voltage to the curves. Second, when set for FET testing, the polarity of the gate voltage stair step waveform doesnt match the desired polarity of the drain-source voltage.

Newly spotted 50-meter asteroid tops Risk List:

Valentine's Day 2046 could be memorable for a number of reasons. Not only might you receive a card from an admirer you never knew you had, but you might also witness a large asteroid slamming into Earth and causing widespread devastation.

Hopefully the only delivery anyone will be getting that day is a card, but scientists say that a 49-meter-wide asteroid discovered last week is currently calculated to have a 1-in-625 chance of hitting our planet in a couple of decades from now.

The rock, called 2023 DW, now sits atop the European Space Agency's Risk List as the only one with a "1" rating on the Torino scale, which is used for categorizing the impact hazard of near-Earth objects.

[...] As asteroid 2023 DW was only discovered a few days ago, scientists are continuing with their analysis to determine more precisely the characteristics of the rock, which is similar in size to an Olympic swimming pool.

[...] If later analysis suggests an increased risk of 2023 DW crashing into Earth, it would be a golden opportunity for NASA to deploy its asteroid deflection system. The technology was tested last year with great success when it smashed a spacecraft into a distant asteroid, with the force of the impact altering the rock's course.

As Crystal pointed out in her email to Undeadly, Miod Vallat (miod@) has committed fixes.

Theres a good chance that if you build something which includes the ability to top up a lithium-ion battery, its going to involve the incredibly common TP4056 charger IC. Now, theres certainly nothing wrong with that. Its a decent enough chip, and there are countless pre-made modules out there that make it extremely easy to implement. But if the chip shortage has taught us anything, its that alternatives are always good.

So wed suggest bookmarking this opensource hardware Li-Ion battery charger design from [Shahar Sery]. The circuit uses the BQ24060 from Texas Instruments, which other than the support for LiFePO4 batteries, doesnt seem to offer anything too new or exciting compared to the standard TP4056. But thats not the point this design is simply offered as a potential alternative to the TP4056, not necessarily an upgrade.

The results of the great DB debate on The Register were announced. Although it was a close-run race, and RDBMS was well ahead at several points during the week before a late surge for graph DBs yesterday. Over 2,000 readers voted. This debate is a part of the current spotlight on databases.

Our first contributor, arguing FOR the motion, was Andy Pavlo, associate professor of databaseology at Carnegie Mellon University. Pavlo's starting point on Monday was that graph DBMSs are "fundamentally flawed and, for most applications, inferior to relational DBMSs."

Jim Webber, Neo4j's chief scientist and a professor of computer science at Newcastle University, arguing AGAINST, said in his rebuttal that he could not back the idea that "relational can do anything" and rejected the assertion that graph databases cannot properly support views and migrations.

Then, on Wednesday, Pavlo threw down the gauntlet, stating that abandoning the relational database model would be akin to "reinventing the wheel." He also doubled down on a public wager he'd previously made that graph databases won't overtake relational databases in 2030 by marketshare. He has promised that if he loses, Pavlo will replace his official CMU photo with one of him wearing a shirt that says "Graph Databases Are #1."

Webber then countered this in his Thursday argument, noting that the pending standard for graphs, GQL, is overseen by the same ISO committee that delivered SQL. If SQL extensions were enough to solve the graph problem, the committee wouldn't have bothered itself, he seemed to be saying. Instead, it decided graphs were different enough to warrant a full query language.

Webber also mentioned: In late 2010, I visited former colleagues at the University of Sydney, Australia. I gave a talk on graph databases and ended it by lightheartedly saying something like, "This technology category is going to catch on. You're going to ignore it for now, but in about a decade you will become interested and start telling us that we've done it all wrong."

Several papers from CIDR 2023 were cited in the discussion.

HAPPY 40th ANNIVERSARY TO THE ACORN ELECTRON COMPUTER!

This year (2023) marks the fortieth anniversary of the Acorn Electron computer!

Heres a summary of the Acorn Electrons pros and cons

• BBC BASIC programming language built in, which could also be mixed with 6502 Assembly Language in the same program
• Most BBC BASIC programs could run on the Acorn electron as well
• It could display text in 80 columns, as well as 40 columns and 20 columns
• Its highest resolution display mode was 640256 in 2 colours
• It was featured on the TV series Me and My Micro presented by Fred Harris as one of only two computers which they used to teach BASIC programming. The other was the Sinclair ZX Spectrum.
• It lacked the many interfaces of the BBC micro, which most people may never have used, but they were partly responsible for the BBC Micros higher price
• It lacked the three channel sound synthesizer chip of the BBC micro, having only a one channel tone generator
• It could only display 8 different colours, as used in Teletext/Videotext
• It lacked the Teletext/Videotext display mode of the BBC Micro, which was called MODE 7

To sum this up, the Acorn Electron had almost everything I was looking for in a computer! I must emphasise th...

If youve spent much time looking through a microscope, you know that their narrow depth of field can be a bit challenging to deal with. Most microscopes are designed to only have a very thin slice of the specimen in focus, so looking at anything above or below that plane requires a focus adjustment. Its tedious and fussy, and that makes it a perfect target for automation.

The goal behind [ItMightBeWorse]s microscope mods is focus stacking, a technique where multiple images of the same sample taken at different focal planes can be stitched together so that everything appears to be in focus. Rather than twist knobs and take pictures manually, he built a simpler Arduino-based rig to do the job for him. Focus control is through a small stepper motor connected to the fine focus knob of the scope, while the DSLR camera shutter is triggered throug...

Results come from a lab that had an earlier superconductivity paper retracted:

On Wednesday, a paper was released by Nature that describes a mixture of elements that can superconduct at room temperature. The work follows a general trend of finding new ways of stuffing hydrogen into a mixture of other atoms by using extreme pressure. This trend produced a variety of high-temperature superconductors in previous research, though characterizing them was difficult because of the pressures involved. This new chemical, however, superconducts at much lower pressures than previous versions, which should make it easier for others to replicate the work.

The lab that produced the chemical, however, had one of its earlier papers on high-temperature superconductivity retracted due to a lack of details regarding one of its key measurements. So, it's a fair bet that many other researchers will try to replicate it.

The form of superconductivity involved here requires that electrons partner up with each other, forming what are called Cooper pairs. One of the things that encourages Cooper pair formation is a high-frequency vibration (called a phonon) among the atomic nuclei that these electrons are associated with. That's easier to arrange with light nuclei, and hydrogen is the lightest around. So finding ways to stuff more hydrogen into a chemical is thought to be a viable route toward producing higher-temperature superconductors.

The surest way of doing that, however, involves extreme pressures. These pressures can induce hydrogen to enter the crystal structure of metals or to form hydrogen-rich chemicals that are unstable at lower pressures. Both of these approaches have resulted in chemicals with very high critical temperatures, the highest point at which they'll support superconductivity. While these have approached room temperature, however, the pressures required were multiple Gigapascalswith each Gigapascal being nearly 10,000 times the atmospheric pressure at sea level.

In essence, this involves trading off impractical temperatures for impractical pressures.
