Researchers Build Complex 3D-Printed, Carbon-Absorbing Bridge Inspired by Bones

Concrete accounts for about 8% of the world’s greenhouse gas emissions, notes CNN. But a research team at the University of Pennsylvania just used a robotic 3D printer to construct a bridge with “complex, lattice-like patterns” that are just as strong and durable — but with materials that absorb more carbon dioxide.

Check out the photos of the “Diamanti” projects “post-tensioned concrete canopy”. And CNN’s report includes an animated photo showing the 3D printer in action:

While most regular concrete absorbs carbon dioxide (up to 30% of its production emissions over its entire life cycle, according to some research), Diamanti’s enhanced concrete mixture absorbs 142% more carbon dioxide than conventional concrete mixes. Its first design, a pedestrian bridge, uses 60% less material while retaining mechanical strength, says Masoud Akbarzadeh, an associate professor of architecture at the University of Pennsylvania and director of the lab that spearheaded the project.

“Through millions of years of evolution, nature has learned that you don’t need material everywhere,” says Akbarzadeh. “If you take a cross section of a bone, you realize that bone is quite porous, but there are certain patterns within which the load (or weight) is transferred.” By mimicking the structures in certain porous bones — known as triply periodic minimal surface (TPMS) structures — âDiamanti also increased the surface area of the bridge, increasing the concrete mixture’s carbon absorption potential by another 30%… According to Akbarzadeh, 3D printing reduces construction time, material, and energy use by 25%, and its structural system reduces the need for steel by 80%, minimizing use of another emissions-heavy material. He added that using the technique with Diamanti’s concrete significantly cuts greenhouse gas emissions compared to regular construction techniques, and reduces construction costs by 25% to 30%.

“Even without the material innovation, the higher surface itself allows higher CO2 absorption,” one engineering lecturer tells CNN. The project was a collaboration with chemical company Sika, funded with grants from the U.S. Energy Department, and is now preparing its first full-size prototype in France.
The team has published their findings in the journal Advanced Functional Materials earlier this year.

Texas hit with a pair of lawsuits for its app store age verification requirements

Texas could have a serious legal battle on its hands thanks to an age verification law for app stores that it recently enacted. In response to the Texas App Store Accountability Act, the Computer & Communications Industry Association (CCIA) filed a lawsuit that argues the new order goes against First Amendment rights. The not-for-profit trade association has Amazon, Apple and Google amongst its members.

The law goes into effect on New Year’s Day and requires app store users to verify their age before downloading apps or making in-app purchases. If underage, users have to get parental consent each time they want to download an app or make another in-app purchase. Along with those stipulations, the suit claims that there’s an additional burden on developers, who have to “age-rate” their apps for different age groups. 

“This Texas law violates the First Amendment by restricting app stores from offering lawful content, preventing users from seeing that content, and compelling app developers to speak of their offerings in a way pleasing to the state,” Stephanie Joyce, senior vice president and chief of staff for the CCIA, said in a press release.

Along with CCIA, a student advocacy group called Students Engaged in Advancing Texas (SEAT) filed a similar lawsuit objecting to Texas’ upcoming app store requirements. Davis Wright Tremaine LLP, the firm representing SEAT and the two high school students named in the lawsuit, said the law “violates the First Amendment by imposing sweeping restrictions on access to protected speech and information.” The law firm also noted the potential dangers associated with collecting personal information, like government IDs, when it comes to verifying identity.

‘How We Sharpened the James Webb Telescope’s Vision From a Million Kilometers Away’

The James Webb Space Telescope gets its highest resolution with the aperture masking interferometer (or AMI), “a tiny piece of precisely machined metal that slots into one of the telescope’s cameras,” according to a new article by Benjamin Pope, an associated math professor at Macquarie University.
“We can finally present its first successful observations of stars, planets, moons and even black hole jets.”

[AMI] was put on Webb to diagnose and measure any blur in its images. Even nanometres of distortion in Webb’s 18 hexagonal primary mirrors and many internal surfaces will blur the images enough to hinder the study of planets or black holes, where sensitivity and resolution are key. AMI filters the light with a carefully structured pattern of holes in a simple metal plate, to make it much easier to tell if there are any optical misalignments. We wanted to use this mode to observe the birth places of planets, as well as material being sucked into black holes. But before any of this, AMI showed Webb wasn’t working entirely as hoped.
At very fine resolution — at the level of individual pixels — all the images were slightly blurry due to an electronic effect: brighter pixels leaking into their darker neighbours. This is not a mistake or flaw, but a fundamental feature of infrared cameras that turned out to be unexpectedly serious for Webb. This was a dealbreaker for seeing distant planets many thousands of times fainter than their stars a few pixels away: my colleagues quickly showed that its limits were more than ten times worse than hoped. So, we set out to correct it…

We built a computer model to simulate AMI’s optical physics, with flexibility about the shapes of the mirrors and apertures and about the colours of the stars. We connected this to a machine learning model to represent the electronics with an “effective detector model” — where we only care about how well it can reproduce the data, not about why. After training and validation on some test stars, this setup allowed us to calculate and undo the blur in other data, restoring AMI to full function. It doesn’t change what Webb does in space, but rather corrects the data during processing. It worked beautifully — the star HD 206893 hosts a faint planet and the reddest-known brown dwarf (an object between a star and a planet). They were known but out of reach with Webb before applying this correction. Now, both little dots popped out clearly in our new maps of the system… With the new correction, we brought Jupiter’s moon Io into focus, clearly tracking its volcanoes as it rotates over an hour-long timelapse.
“This correction has opened the door to using AMI to prospect for unknown planets at previously impossible resolutions and sensitivities…” the article points out.
“Our results on painstakingly testing and enhancing AMI are now released on the open-access archive arXiv in a pair of papers.”

Court reduces damages Meta will get from spyware maker NSO Group but bans it from WhatsApp

US District Judge Phyllis Hamilton has reduced the damages Meta is getting from the NSO Group from $167 million to $4 million, but she has also ordered the Israeli spyware maker to stop targeting WhatsApp. If you’ll recall, Meta sued the NSO Group in 2019 over its Pegasus spyware, which it said was used to spy on 1,400 people from 20 countries, including journalists and human rights activists. Meta said at the time that Pegasus can infect targets’ devices even without their participation by sending text messages with malicious codes to WhatsApp. Even a missed call is enough to infect somebody’s device. 

According to Courthouse News Service, Hamilton reduced the damages because they would need to follow a legal framework designed to proportionate damages. However, she has also handed down a permanent injunction on the NSO Group’s efforts to break into WhatsApp. In her decision, she took note of statements made by NSO’s lawyers and its own CEO revealing that it hasn’t stopped collecting WhatsApp messages and trying to get around the messaging app’s security measures. The defendants previously said that the injunction Meta was requesting would “put NSO’s entire enterprise at risk” and “force NSO out of business,” since WhatsApp is one of the Pegasus spyware’s main ways to infect targets’ devices. 

“Today’s ruling bans spyware maker NSO from ever targeting WhatsApp and our global users again,” said Will Cathcart, Head of WhatsApp. “We applaud this decision that comes after six years of litigation to hold NSO accountable for targeting members of civil society. It sets an important precedent that there are serious consequences to attacking an American company.” 

Hamilton wrote that the proposed injunction requires the Israeli company to delete and destroy computer code related to Meta’s platforms, and that she concluded that the provision is “necessary to prevent future violations, especially given the undetectable nature of defendants’ technology.” It’s not quite clear how Meta will ensure that the NSO Group doesn’t use WhatsApp to infect its users’ devices again. Notably, the NSO Group was recently acquired by an American investment group that invested tens of millions of dollars into it to take controlling ownership.

Are Parts of the World Retreating on Electric Vehicles?

Canada’s Prime Minister “paused an electric-vehicle sales mandate that was set to take effect next year,” reports the Wall Street Journal, which argues a kind of retreat from electric-vehicle ambitions “is spreading around the globe.”

Even the U.K.’s Prime Minister “has allowed for a more flexible timetable to hit the country’s EV targets.” And demand is expected to drop in the U.S., where global consulting firm AlixPartners now predicts EVs will make up 18% of new-vehicle sales by 2030 — just half of what they’d predicted two years ago:
j
U.S. automaker GM will take a $1.6 billion charge “because of sinking EV sales,” reports the Wall Street Journal, “a shift it blamed on recent moves by the U.S. government to end EV subsidies and regulatory mandates… That might just be the beginning of a financial reckoning from automakers that poured billions into new electric models — from sports cars and sedans to big pickups and sport-utility vehicles — to try to get ready for the government-backed EV mandates.

Automakers have been saying that consumers aren’t adopting EVs as quickly as expected, and government efforts to proliferate the technology are hammering their bottom lines. GM, in announcing its charge, said it is reassessing EV capacity and warned that more losses are possible…Carmakers argue the EV business model is an unprofitable proposition given still-high battery costs, spotty car-charging networks and dwindling government subsidies.

Incentive programs have ended or have been pared back across Europe and in the U.S. and Canada.

Volkswagen, burdened with massive electrification costs, helped spur the reckoning in Europe when it said it would cut 35,000 jobs as part of a deal with its union. The move sent shock waves through the region’s political establishment. Weeks later, the EU launched a “strategic dialogue” with the automotive industry that led to a more flexible timetable for automakers to meet its emissions rules for 2025.

Reddit Mod Warns ‘Do Not Trust’ AI-Powered ‘Reddit Answers’ After It Posts Dangerous Health Advice

In Reddit’s “Family Medicine” subreddit, a moderator noticed earlier this week that the AI-powered “Reddit Answers” was automatically responding to posters, typically with “something related to what was posted.” Unfortunately, that moderator says, Reddit Answers “has been spreading grossly dangerous misinformation.”And yet Reddit’s moderators “cannot disable this feature.”

Elsewhere a healthcare worker described what happened when they tested Reddit Answers:

I made a post in r/familymedicine and a link appeared below it with information on treating chronic pain. The first post it cited urged people to stop their prescribed medications and take high-dose kratom which is an illegal (in some states) and unregulated substance. I absolutely do not endorse this…

I also asked about the medical indications for heroin. One answer warned about addiction and linked to crisis and recovery resources. The other connects to a post where someone claims heroin saved their life and controls their chronic pain. The post was encouraging people to stop prescribed medications and use heroin instead. Heroin is a schedule I drug in the US which means there are no acceptable uses. It’s incredibly addictive and dangerous. It is responsible for the loss of so many lives…

The AI-generated answers could easily be mistaken as information endorsed by the sub it appears in. r/familymedicine absolutely does not endorse using heroin to treat chronic pain. This feature needs to be disabled in medical and mental health subs, or allow moderators of these subreddits to opt out. Better filters are also needed when users ask Reddit Answers health related questions. If this continues there will be adverse outcomes. People will be harmed. This needs to change.
Two days ago an official Reddit “Admin” posted that “We’ve made some changes to where Answers appears based on this feedback,” adding that beyond that Reddit “will continue to tweak based on what we’re seeing and hearing.” But the “Family Medicine” subreddit still has a top-of-page announcement warning every user there…

“We do NOT and CANNOT endorse Reddit Answers at this time and urge every user of this sub to disregard anything it says.”

Google has killed Privacy Sandbox

Google’s Privacy Sandbox is officially dead. In an update on the project’s website, Google Vice President Anthony Chavez has announced that the company was sunsetting the remaining technologies developed for Sandbox due to their “low levels of adoption.” A spokesperson has confirmed to AdWeek that Google isn’t just killing those technologies, it’s retiring the whole initiative altogether. “We will be continuing our work to improve privacy across Chrome, Android and the web, but moving away from the Privacy Sandbox branding,” the spokesperson said. “We’re grateful to everyone who contributed to this initiative, and will continue to collaborate with the industry to develop and advance platform technologies that help support a healthy and thriving web.”

The company launched Privacy Sandbox in 2019 as a future replacement to third-party cookies. It’s a set of open standards that are supposed to enable personalized ads without divulging identifying data. Over the years, Google’s plans to deprecate third-party cookies got pushed back again and again due to a series of delays and regulatory hurdles. Specifically, both the UK’s Competition and Markets Authority (CMA) and the US Department of Justice looked into the Privacy Sandbox out of concerns that it could harm smaller advertisers. 

In 2024, Google ultimately decided not to kill third-party cookies in Chrome and instead chose to roll out “a new experience in Chrome that lets people make an informed choice that applies across their web browsing.” Just this April, Google announced that it wasn’t going to make any to changes to how third-party cookies work on the Chrome browser at all, and that it was going to “maintain [its] current approach to offering users third-party cookie choice in Chrome.” At the time, the company said that it was going to keep the Privacy Sandbox initiative alive, but things have clearly changed since then. Chavez wrote in the latest update that Google will “continue to utilize learnings from the retired Privacy Sandbox technologies.”

Email Bombs Exploit Lax Authentication In Zendesk

Cybercriminals are exploiting weak email authentication settings in Zendesk, using the platform’s customer support systems to bombard targets with thousands of spam and harassing messages that appear to come from legitimate companies like The Washington Post, Discord, and NordVPN. KrebsOnSecurity reports: Zendesk is an automated help desk service designed to make it simple for people to contact companies for customer support issues. Earlier this week, KrebsOnSecurity started receiving thousands of ticket creation notification messages through Zendesk in rapid succession, each bearing the name of different Zendesk customers, such as CapCom, CompTIA, Discord, GMAC, NordVPN, The Washington Post, and Tinder.

The abusive missives sent via Zendesk’s platform can include any subject line chosen by the abusers. In my case, the messages variously warned about a supposed law enforcement investigation involving KrebsOnSecurity.com, or else contained personal insults. Moreover, the automated messages that are sent out from this type of abuse all come from customer domain names — not from Zendesk. […]

In all of the cases above, the messaging abuse would not have been possible if Zendesk customers validated support request email addresses prior to sending responses. Failing to do so may make it easier for Zendesk clients to handle customer support requests, but it also allows ne’er-do-wells to sully the sender’s brand in service of disruptive and malicious email floods. “We recognize that our systems were leveraged against you in a distributed, many-against-one manner,” said Carolyn Camoens, communications director at Zendesk. “We are actively investigating additional preventive measures. We are also advising customers experiencing this type of activity to follow our general security best practices and configure an authenticated ticket creation workflow.”

Roberta Williams’ The Colonel’s Bequest was a different type of adventure game

Even in my youth, I always loved the idea of point-and-click adventure games more than I did the reality. I appreciated how they transported me to other worlds, each with its own rules, histories, and interesting characters. However, like many people, I often ran up against the harsh reality of solving bizarre and obtuse puzzles in a time before Internet walkthroughs.

I almost never actually finished point-and-click adventure games for that reason—but there is one major exception: I completed Robert Williams’ The Colonel’s Bequest several times.

One of the last Sierra adventure games to still use a text parser, The Colonel’s Bequest follows a young woman named Laura Bow as she visits a mansion in the Southern US belonging to her college friend’s grandfather, Colonel Henri Dijon. While she’s there, a dispute breaks out over the colonel’s will, and it becomes clear a murderer is on the loose.

A spooky NES platformer, more N++ and other new indie games worth checking out

Welcome to our latest roundup of what’s going on in the indie game space. I’ve reluctantly paused Ball x Pit for long enough to share some neat new releases and more details on upcoming games — some of which are arriving very soon. We’ve got a notable update for a classic as well. 

Steam Next Fest is taking place at the minute, and you still have until Monday to join in by checking out some of the many, many demos that have gone live for the event. Thanks partially (okay, almost entirely) to being unable to escape Ball x Pit, I’ve only tried a fewm Next Fest demos so far. 

I’m a fan of Aerial_Knight’s Never Yield and after last year’s sequel, it’s cool to see solo developer Neil Jones (aka Aerial_Knight) trying something totally different. Aerial_Knight’s DropShot is a skydiving first-person shooter with finger guns and dragons. It’s a single-player game in which the aim is to take out your opponents and reach the ground first. Like Jones’ previous games, it’s stylish and fast-paced. I’m planning to check out the full game when it arrives down the line.

It certainly helps to be a fast, accurate typer when you put words together for a living, but I wasn’t quick or precise enough to win any rounds in the Final Sentence demo. This is a battle royale for up to 100 players in which you’re at a typewriter and have to bash out sentences (or other strings of letters, numbers and symbols) in a race to the finish. If you run out of time, make too many mistakes or don’t win, it’s lights out, courtesy of the masked figure with a revolver who’s standing in front of you. 

There are some nice touches here. Having to type out the rules in the first few rounds is a clever idea on the part of developer Button Mash. I haven’t won a round myself yet (I finished in second place a couple of times), but watched some streamers play. It’s very funny when the winning player flips the bird at the guy holding a revolver in front of them.

Final Sentence is coming to Steam later this year. Maybe I’ll have learned how to spell “sphinx” by then.

There are a few other Next Fest demos I’d like to try this weekend, namely:

I’ve been looking forward to Skate Story for forever, but I think I’m going to skip that demo. I’m already sold and I’m fine with waiting a couple more months before playing the whole thing.

There are a couple of showcases coming up next week that might be worth keeping an eye on. The third annual edition of DreadXP’s indie horror showcase is set for 1PM ET on October 23. You can catch that on the publisher’s YouTube channel.

Two hours later, you’ll be able to tune into the Galaxies Autumn showcase. This will feature more than 50 games, including world premieres, gameplay trailers and other announcements. Games that will be featured include PowerWash Simulator 2, Mouse: PI For Hire and Denshattack, all of which are firmly on my to-play list.

New releases

Mister Scary is a weird little guy. I love when you get to play a game as a weird little guy. The game of the same name is a spooky NES homebrew platformer from Calgames. 

Mister Scary can stomp on his enemies, or freeze or burn them after eating a snack. When Mister Scary ducks, he becomes immune to damage because he’s taking a nap. I appreciate that. Nothing scary can happen while you’re snoozing.

Mister Scary is $10 on Itch. You’ll need to plug the ROM into a NES emulator to become Mister Scary.

The only reason I still have Flash Player installed on my PC is so I can open N, which sits on my desktop, once in a while. I’ve been playing that classic freeware platformer for a long time, and now there’s a good reason for many people to revisit the third entry in the series. 

As a thank you to the N++ community, Metanet Software is releasing a free update to mark the 10th anniversary of the game’s PS4 debut. TEN++ is said to include the developer’s “most challenging levels yet.” Given how darn tough these games are already, that’s saying something. The update is available now on Steam and it’s coming to the console versions of N++ soon.

The Cabin Factory is an anomaly-hunting (i.e. spot the difference) game in the style of The Exit 8. You’ll examine horror-themed cabins that are built for use in movies and theme parks to make sure they aren’t actually haunted. If you spot an anomaly, you’ll want to get out of the cabin post haste.

This $3 horror walking sim from International Cat Studios and publisher Future Friends Games debuted on Steam last year, and it just hit consoles in time for Halloween. It’s out now on PS4, PS5, Xbox One, Xbox Series X/S and Nintendo Switch.

Upcoming 

After CloverPit and Ball x Pit, I was planning to take a break from roguelikes/roguelites before diving into Hades 2. Alas, the latest game from the legendary Ron Gilbert now has a release date, and it’s very soon!

In Death by Scrolling, the aim is to collect enough gold to pay a ferryman so you can escape purgatory. However, there’s a wall of fire coming after you the whole time, so you’ll need to keep moving in order to try to stay alive. You’ll also need to avoid or stun an unkillable grim reaper as you collect gold and gems that unlock upgrades. 

Death by Scrolling is from Gilbert’s Terrible Toybox and MicroProse Software. It’s coming to Steam on October 28.

There’s a lot going on in Silly Polly Beast. It’s safe to say this game is a shooter, but the release date trailer rapidly flits between perspectives and genres. There’s an emphasis on survival horror, along with puzzles and stealth segments. Polly will even sometimes remove the board that’s strapped to her back for some skateboarding sequences. 

This is said to have a story that morphs and evolves as much as the gameplay does. After escaping her hellish orphanage, Polly lands right in the underworld and has to navigate her way out of that too. 

Developer Andrei Chernyshov and publisher Top Hat Studios are behind Silly Polly Beast. It’s coming to Steam, PS4, PS5, Xbox One, Xbox Series X/S and Nintendo Switch on October 28.

Also coming to Steam on October 28 is a project from Autoscopia Interactive that’s designed to be played in a single sitting. As Long As You’re Here is a first-person game that places you in the role of a woman with Alzheimer’s disease. Her memories of the past, including her late brother, blend into the present as Annie settles into living with her family. 

As Long As You’re Here started as a student project by Marlène Delrive, who was trying to better understand what her grandmother was experiencing in her final years. “The aim is to create a mature and nuanced experience that shows the difficult repercussions of losing not only your memory, but also your agency and sense of time and place,” the developers said.

Let’s close things out with a new trailer for Goodnight Universe. This is a cinematic adventure in which you play as a six-month-old baby. This particular infant is incredibly intelligent and has psychic powers. Isaac simply desires familial love and acceptance but (shock horror!) a tech company wants to take away the tot.

As with Nice Dreams’ last game (the stupendous Before Your Eyes), you control Goodnight Universe with your peepers via your device’s camera. It seems fascinating, and I really have to check out the Next Fest demo. Publisher Skybound Games is bringing it to Steam, Xbox Series X/S, PS5, Nintendo Switch and Switch 2 on November 11.
