Neanderthal adhesives were made through a complex synthesis process

As Homo sapiens, we often consider ourselves to be the most intelligent hominins. But that doesn’t mean our species was the first to discover everything; it appears that Neanderthals found a way to manufacture synthetics long before we ever did.

Neanderthal tools might look relatively simple, but new research shows that Homo neanderthalensis devised a method of generating a glue derived from birch tar to hold them together about  200,000 years ago—and it was tough. This ancient superglue made bone and stone adhere to wood, was waterproof, and didn’t decompose. The tar was also used a hundred thousand years before modern humans came up with anything synthetic.

A transformation

After studying ancient tools that carry residue from this glue, a team of researchers from the Eberhard Karls University of Tübingen and other institutions in Germany found evidence that this glue wasn’t just the original tar; it had been transformed in some way. This raises the question of what was involved in that transformation.

To see how Neanderthals could have converted birch tar into glue, the research team tried several different processing methods. Any suspicion that the tar came directly from birch trees didn’t hold up because birch trees do not secrete anything that worked as an adhesive. So what kind of processing was needed?

Each technique that was tested used only materials that Neanderthals would have been able to access. Condensation methods, which involve burning birch bark on cobblestones so the tar can condense on the stones, were the simplest techniques used—allowing bark to burn above ground doesn’t really involve much thought beyond lighting a fire.

The other methods involved a recipe where the bark was not actually burned but heated after being placed underground. Two of these methods involved burying rolls of bark in embers that would heat them and produce tar. The third method would distill the tar. Because there were no ceramics during the Stone Age, sediment was shaped into upper and lower structures to hold the bark, which was then heated by fire. Distilled tar would slowly drip from the upper structure into the lower one.

Coming to a Rooftop Near You: A UFO-Spotting Spycam

An ex-spook made an incredible claim about aliens last week. David Charles Grusch, a former official with the U.S. National Geospatial Intelligence Agency and the U.S. National Reconnaissance Office, told The Debrief that the feds possess what the publication described as “intact and partially intact craft of non-human origin.”

But there’s a catch: There’s no actual evidence to back up Grusch’s claim. No evidence that the government is sitting on a bunch of derelict alien spacecraft. And no evidence aliens even exist, for that matter. Worse for Fox Mulder-style true believers, no one’s even looking for extraterrestrials near Earth—at least not with any real scientific rigor.

That last caveat is about to change. Harvard physicist Avi Loeb and his alien-hunting startup, the Galileo Project, is building what they hope will be a global network of skyward-pointing sensors whose purpose is to scan, look, and listen for UFOs—or, to borrow the in-vogue and official U.S. government term, Unexplained Aerial Phenomena (UAP).

US approves chicken made from cultivated cells, the nation’s first ‘lab-grown’ meat

For the first time, U.S. regulators on Wednesday approved the sale of chicken made from animal cells, allowing two California companies to offer “lab-grown” meat to the nation’s restaurant tables and eventually, supermarket shelves.

The Agriculture Department gave the green light to Upside Foods and Good Meat, firms that had been racing to be the first in the U.S. to sell meat that doesn’t come from slaughtered animals — what’s now being referred to as “cell-cultivated” or “cultured” meat as it emerges from the laboratory and arrives on dinner plates.

The move launches a new era of meat production aimed at eliminating harm to animals and drastically reducing the environmental impacts of grazing, growing feed for animals and animal waste.

“Instead of all of that land and all of that water that’s used to feed all of these animals that are slaughtered, we can do it in a different way,” said Josh Tetrick, co-founder and chief executive of Eat Just, which operates Good Meat.

The companies received approvals for federal inspections required to sell meat and poultry in the U.S. The action came months after the U.S. Food and Drug Administration deemed that products from both companies are safe to eat. A manufacturing company called Joinn Biologics, which works with Good Meat, was also cleared to make the products.

Aliens Or Not, Secret Crash Retrieval Programs Are A Very Real Thing

News first broke just over a week ago that a former career American intelligence officer is alleging the U.S. government is concealing a decades-long top-secret ‘crash retrieval’ program that has overseen the recovery of otherworldly flying machines and their pilots. There remains no hard evidence available to the public to substantiate these claims. Yet the U.S. military and intelligence community’s shadowy crash retrieval programs are a very real thing, although the ones we know about are focused on foreign, not alien, technology.

These secretive endeavors are part of a larger ecosystem focused on gathering intelligence — through examining, reverse engineering, and testing — non-U.S. weapon systems and other equipment through so-called Foreign Materiel Exploitation, or FME. This extensive espionage ecosystem, honed over nearly a century of operations, lives in the shadows, but remains an indispensable discipline that has paid off massively time and time again.

Synthetic human embryos are created in the lab with NO egg or sperm: Scientists announce historic breakthrough raising hopes for new treatments for miscarriage and rare genetical disorders – but development poses huge ethical dilemmas

Human embryos made without eggs or sperm have been created in a scientific breakthrough which is bound to raise serious ethical and legal questions.

They were produced in a joint project between Cambridge University and the California Institute of Technology and resemble embryos in the earliest stages of human development.

They do not have the beginnings of a brain or a beating heart, but do include cells which would go on to form the placenta and yolk sac.

Scientists believe that their finding could provide significant insight and aid research into rare genetic disorders and the biological causes of miscarriage.

But the synthetic embryos are not covered by laws in the UK or in most countries around the world, meaning that they come with serious ethical and legal issues regarding the use of human embryos in a lab.

Until this breakthrough, scientists had to adhere to the 14-day rule which meant they were limited to allowing embryos to develop in a lab for a maximum of two weeks.

After this point researchers would have to wait until further along its development to pick up their study, relying on pregnancy scans and embryos donated to research. 

The desire to understand this period of an embryo’s development – which starts at day 14 and ends around day 28 – was the main motivation behind the work to create synthetic human embryos.

Professor Magdalena Zernicka-Goetz, a fellow at the University of Cambridge, described the work yesterday at the International Society for Stem Cell Research’s annual meeting in Boston: ‘We can create human embryo-like models by the reprogramming of [embryonic stem] cells.’

Before the talk, she told The Guardian: ‘It’s beautiful and created entirely from embryonic stem cells.’

While it is not yet clear if the synthetic embryos could continue developing beyond their early stages, implanting them into a patient’s womb would be illegal and there is no near-term prospect of them being used for medical purposes.

Amazon shuts down customer’s smart home for a week after delivery driver claimed he heard racist slur through Ring doorbell – even though no one was home

Amazon reportedly shut down a customer’s smart home after the delivery driver claimed he heard a racial slur coming through the doorbell, even though no one was home. 

Brandon Jackson, of Baltimore, Maryland, came home on May 25 to find that he had been locked out of his Amazon Echo, which many devices, including his lights, are connected to. 

He would later learn that Amazon locked him out of his account after a delivery driver dropped off a package the day before. Jackson, an engineer at Microsoft, said ‘everything seemed fine’ after the package arrived at his home and had initially thought he was locked out because someone had tried to ‘access my account repeatedly, triggering a lockout.’ 

But none of that was true. A representative directed him to an email he received from an executive that provided a phone number to call. When he called the number, he was told in a ‘somewhat accusatory’ tone that the driver had reported ‘receiving racist remarks’ from his doorbell.

‘This incident left me with a house full of unresponsive devices, a silent Alexa, and a lot of questions,’ he wrote on Medium.

The world’s top H.P. Lovecraft expert weighs in on a monstrous viral meme in the A.I. world

Artificial intelligence is scary to a lot of people, even within the tech world. Just look at how industry insiders have co-opted a tentacled monster called a shoggoth as a semi-tongue-in-cheek symbol for their rapidly advancing work.

But their online memes and references to that creature — which originated in influential late author H.P. Lovecraft’s novella “At the Mountains of Madness” — aren’t quite perfect, according to the world’s leading Lovecraft scholar, S.T. Joshi.

If anyone knows Lovecraft and his wretched menagerie, which includes the ever-popular Cthulhu, it’s Joshi. He’s edited reams of Lovecraft collections, contributed scores of essays about the author and written more than a dozen books about him, including the monumental two-part biography “I Am Providence.”

So, after The New York Times recently published a piece from tech columnist Kevin Roose explaining that the shoggoth had caught on as “the most important meme in A.I.,” CNBC reached out to Joshi to get his take — and find out what he thought Lovecraft would say about the squirmy homage from the tech world.

“While I’m sure Lovecraft would be grateful (and amused) by the application of his creation to AI, the parallels are not very exact,” Joshi wrote. “Or, I should say, it appears that AI creators aren’t entirely accurate in their understanding of the shoggoth.”

An Anti-Porn App Put Him in Jail and His Family Under Surveillance

ON A WEDNESDAY morning in May, Hannah got a call from her lawyer—there was a warrant out for her husband’s arrest. Her thoughts went straight to her kids. They were going to come home from school and their father would be gone. “It burned me,” Hannah says, her voice breaking. “He hasn’t done anything to get his bond revoked, and they couldn’t prove he had.”

Hannah’s husband is now awaiting trial in jail, in part because of an anti-pornography app called Covenant Eyes. The company explicitly says the app is not meant for use in criminal proceedings, but the probation department in Indiana’s Monroe County has been using it for the past month to surveil not only Hannah’s husband but also the devices of everyone in their family. To protect their privacy, WIRED is not disclosing their surname or the names of individual family members. Hannah agreed to use her nickname.

Prosecutors in Monroe County this spring charged Hannah’s husband with possession of child sexual abuse material—a serious crime that she says he did not commit and to which he pleaded not guilty. Given the nature of the charges, the court ordered that he not have access to any electronic devices as a condition of his pretrial release from jail. To ensure he complied with those terms, the probation department installed Covenant Eyes on Hannah’s phone, as well as those of her two children and her mother-in-law. 

In near real time, probation officers are being fed screenshots of everything Hannah’s family views on their devices. From images of YouTube videos watched by her 14-year-old daughter to online underwear purchases made by her 80-year-old mother-in-law, the family’s entire digital life is scrutinized by county authorities. “I’m afraid to even communicate with our lawyer,” Hannah says. “If I mention anything about our case, I’m worried they are going to see it and use it against us.”

Covenant Eyes is part of a multimillion-dollar market of “accountability” apps sold to churches and parents as a tool to police online activity. For a monthly fee, the app monitors every single thing a user does on their devices, then sends the data it collects, including screenshots, to an “ally” or “accountability partner,” who can review the user’s online activities.

Philip K. Dick predicted ChatGPT and its grim ramifications

Philip K. Dick had some strange ideas about the future. In his 40-plus novels and 121 short stories, the science fiction author imagined everything from “mood organs” which allow users to dial up an emotional state including “the desire to watch TV, no matter what’s on” to pay-per-use doors that refuse entrance or exit without sufficient coinage. Characters in Dick’s mind-bending novel “Ubik” (published in 1969 and set in 1992) include a psionic talent scout named G.G. Ashwood, who wears “natty birch-bark pantaloons, hemp-rope belt, peekaboo see-through top and train engineer’s tall hat” and a taxi driver wearing “fuchsia pedal pushers, pink yak fur slippers, a snakeskin sleeveless blouse, and a ribbon in his waist-length dyed white hair.”

But our weird present is looking increasingly like a Philip K. Dick future. While we may not have Deckard’s flying car from “Blade Runner” (adapted from Dick’s novel, “Do Androids Dream of Electric Sheep?”), many of the author’s predictions have materialized in real life after appearing on the big screen, including Dick’s fondness for robo-taxis (who can forget the lovable Johnnycab from 1990’s “Total Recall”?), and the predictive policing Dick called “pre-crime” in his 1956 story, “Minority Report,” which hit the big screens in 2002 with the help of Steven Spielberg and Tom Cruise.  And now it looks like Philip K. Dick may also have predicted ChatGPT.

World’s first baby is born from a transplanted uterus implanted by a robot – and it brings hope to tens of thousands of American women who lack a womb

A baby boy carried in a uterus implanted into his mother by a robot was born in a world first.

The youngster, who has not been named, weighed six pounds and 13 ounces when he was born via planned C-section in Sweden last month. Both the child and his 35-year-old mother are doing well.

The pregnancy was made possible when a family member agreed to donate their uterus to the mother, who then had a fertilized egg implanted into it via IVF. The case marks the first time robots have been used for the procedure.

It will give hope to the tens of thousands of American women who don’t have a uterus — which can be due to cancer or a medical condition — or have one unable to carry infants.

The case was revealed by surgeons at the University of Gothenburg, Sweden, a leader in uterus transplants.

In the surgery, researchers began by removing the uterus in the donor by gradually cutting it away from blood vessels and pulling it out through the vagina.

Small incisions were made in the second patient’s side by the pelvis, and the uterus was implanted into them. It was connected to their blood vessels and vagina.

Surgeons inserted cameras and robotic arms with surgical instruments attached through the small entry holes in the lower belly to carry out the procedure — with the robotic arms being the first for this type of surgery.

The arms were steered via joysticks, with surgeons using consoles to see 3D images of the patient’s insides simultaneously. 

This method is less invasive than the standard uterus transplant, which involves opening up larger openings in patients.

It is also thought to reduce the risk of infections, hemorrhages and allow patients to return to their daily lives faster.
