From the main-event-horizon department: "Researchers have created the first laboratory analog of the 'black hole bomb'," reports ScienceAlert, "a theoretical concept developed by physicists in the 1970s..."
There's no black hole involved; their experiment just simulates the "electromagnetic analogue" of the theoretical concept — the "exponential runaway amplification of spontaneously generated electromagnetic modes."
Or, as ScienceAlert puts it, "It doesn't, just to set your mind at ease, pose any danger. It consists of a rotating aluminum cylinder, placed inside layers of coils that generate magnetic fields that rotate around it, at controllable speeds."
As Roger Penrose proposed in 1971, the powerful rotational energy of a spinning black hole could be used to amplify the energy of nearby particles. Then, physicist Yakov Zel'Dovich figured out that you didn't need a black hole to see this phenomenon in action. An axially symmetrical body rotating in a resonance chamber, he figured, could produce the same energy transfer and amplification, albeit on a much smaller scale. Later work by other physicists found that, if you enclose the entire apparatus in a mirror, a positive feedback loop is generated, amplifying the energy until it explodes from the system.

From the working-at-scale department: Long-time Slashdot reader piojo writes: Tim Friede, Wisconsin man, has been injecting himself with snake venom for 18 years to gain protection from his pet snakes. The antibodies he developed have formed two components of a three-part antivenom, which gives partial or total protection against 18 of 19 species of venomous snakes that were tested. Notably, the antivenom is ineffective against vipers.
From Australia's public broadcaster ABC:
The team's results have been published today in the journal Cell... The new antivenom described in the study is very different to traditional antivenoms, according to Peter Kwong, a biochemist at Columbia University and one of the study's authors.
The scientists call their new antivenom "unparallel," according to the BBC, though the snake enthusiast (a former truck mechanic) had "initially wanted to build up his immunity to protect himself when handling snakes, documenting his exploits on YouTube."
The team is trying to refine the antibodies further and see if adding a fourth component could lead to total protection against elapid snake venom... "Tim's antibodies are really quite extraordinary — he taught his immune system to get this very, very broad recognition," said Professor Peter Kwong [one of the researchers at Columbia University].
In a video interview, CNN shows footage of the man inducing snake bites (calling it "a classic do-not-try-this-at-home moment"). "I have a lot of notes in Excel files," he tells CNN, "where I hit these particular windows to where I know I can boost up before a bite."
"I don't just take the bite, because that can kill you. I properly boost up, and methodically take notes, and weigh the venomes out very specifically..."

From the pulling-on-Threads department: Threads has now grown to over 350 million monthly active users, reports TechCrunch, citing Mark Zuckerberg's comments on a company earnings call. That means Threads grew by 9.4% in roughly 90 days:
That's an increase of 30 million users since the prior quarter, where Meta reported that Threads had 320 million users. The new figure represents increased growth, as Threads added 30 million in the first quarter of this year, compared with 20 million in Q4 2024.
It's also worth noting that in a single quarter, Threads added nearly the same number of users to its network as one of its newer competitors, Bluesky. The latter, a decentralized social app, today has roughly 35 million users.
Zuckerberg also said there's been a 35% increase in time spent on Threads, according to the article, as a result of improvements to its recommendations systems.

From the celebrating-software department: May is Maintainer Month: Celebrating those who secure Open Source
@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The Open Source Initiative is joining "a global community of contributors" for GitHub's annual event "honoring the individuals who steward and sustain Open Source projects."
And the theme of the 4th Annual "Maintainer Month" will be: securing Open Source:
Throughout the month, OSI and our affiliates will be highlighting maintainers who prioritize security in their projects, sharing their stories, and providing a platform for collaboration and learning... Maintainer Month is a time to gather, share knowledge, and express appreciation for the people who keep Open Source projects running. These maintainers not only review issues and merge pull requests — they also navigate community dynamics, mentor new contributors, and increasingly, adopt security best practices to protect their code and users....
- OSI will publish a series of articles on Opensource.net highlighting maintainers whose work centers around security...
- As part of our programming for May, OSI will host a virtual Town Hall [May 21st] with our affiliate organizations and invite the broader Open Source community to join....
- Maintainer Month is also a time to tell the stories of those who often work behind the scenes. OSI will be amplifying voices from across our affiliate network and encouraging communities to recognize the people whose efforts are often invisible, yet essential.
"These efforts are not just celebrations — they are opportunities to recognize the essential role maintainers play in safeguarding the Open Source infrastructure that underpins so much of our digital world," according to the OSI's announcement. And this year they're focusing on three key areas of open source security:
Adopting security best practices in projects and communities
Recognizing contributors who improve project security

From the gold-records department: Slashdot reader sciencehabit shares this excerpt from a new article in Science magazine:
At first, astronomers knew of only one cosmic scenario that fit the bill for the violent formation of "jewelry shop" elements [gold and sliver]: the collision of two ultra-dense stellar corpses called neutron stars.
Now, a second has stepped onto the scene.
As they report this week in The Astrophysical Journal Letters, researchers have discovered signatures of this heavy element formation — called the r-process — in a giant flare first detected from a highly magnetic neutron star in 2004. The flare, which released more energy than our Sun does in a million years as it spewed electrically charged material, has remained shrouded in mystery since its discovery 20 years ago. Researchers quickly traced the outburst to a nearby magnetar, a special breed of neutron star whose magnetic fields are trillions times stronger than Earth's. But ten minutes after the massive flare, a second, fainter signal inexplicably came from the same star.
More r-process sources may still be looming in the dark. The new study accounts for about 10% of the Milky Way's heavy elements, suggesting that astronomers will have to scour the cosmos for even more places where the r-process is hiding. One potential spot is a rare type of supernova that births rapidly rotating neutron stars, says says Anirudh Patel, the new study's lead author and an astronomer at Columbia University. He hopes that with more observations, astronomers will be able to sharpen that picture.... "It's humbling to realize that these were made in such extreme astrophysical environments."

From the was-it-worth-it? department: A 25-year-old from Santa Clarita has pleaded guilty to hacking a Disney employee's computer using malware disguised as an AI art tool, stealing over 1 terabyte of confidential Disney data and threatening to leak it under the guise of a fake Russian hacktivist group. Variety reports: Santa Clarita resident Ryan Mitchell Kramer, 25, pleaded guilty to two felony charges, including one count of accessing a computer and obtaining information and one count of threatening to damage a protected computer. Each charge carries a maximum sentence of five years in federal prison. According to the plea agreement, in early 2024 Kramer posted a computer program on various online platforms that appeared to be used to create AI-generated art, when it really contained a malicious file to gain access to victims' computers.
Between April and May 2024, a Disney employee downloaded the program, and Kramer gained access to the victim's personal and work accounts, including a non-public Disney Slack channel. Kramer dowloaded approximately 1.1 terabytes of confidential data from thousands of Disney Slack channels. In July, Kramer contacted the victim by pretending to be a member of a fake Russian hacktivist group called "Nullbulge" and threatened to leak their personal information and Disney Slack data. On July 12, Kramer publicly released the data, including the victim's bank, medical, and personal information on multiple online platforms.

From the after-decades-of-hype department: An anonymous reader quotes a report from CNN: Driverless trucks are officially running their first regular long-haul routes, making roundtrips between Dallas and Houston. On Thursday, autonomous trucking firm Aurora announced it launched commercial service in Texas under its first customers, Uber Freight and Hirschbach Motor Lines, which delivers time- and temperature-sensitive freight. Both companies conducted test runs with Aurora, including safety drivers to monitor the self-driving technology dubbed "Aurora Driver." Aurora's new commercial service will no longer have safety drivers.
"We founded Aurora to deliver the benefits of self-driving technology safely, quickly, and broadly, said Chris Urmson, CEO and co-founder of Aurora, in a release on Thursday. "Now, we are the first company to successfully and safely operate a commercial driverless trucking service on public roads." The trucks are equipped with computers and sensors that can see the length of over four football fields. In four years of practice hauls the trucks' technology has delivered over 10,000 customer loads. As of Thursday, the company's self-driving tech has completed over 1,200 miles without a human in the truck. Aurora is starting with a single self-driving truck and plans to add more by the end of 2025.
