Surgeons perform world’s first eye transplant
Surgeons have performed the world’s first transplant of an entire human eye, an extraordinary addition to a face transplant — although it’s far too soon to know if the man will ever see through his new left eye.
An accident with high-voltage power lines had destroyed most of Aaron James’ face and one eye. His right eye still works. But surgeons at NYU Langone Health hoped replacing the missing one would yield better cosmetic results for his new face, by supporting the transplanted eye socket and lid.
The NYU team announced Thursday that so far, it's doing just that. James is recovering well from the dual transplant last May and the donated eye looks remarkably healthy.
“It feels good. I still don’t have any movement in it yet. My eyelid, I can’t blink yet. But I’m getting sensation now,” James told The Associated Press as doctors examined his progress recently.
“You got to start somewhere, there’s got to be a first person somewhere,” added James, 46, of Hot Springs, Arkansas. “Maybe you’ll learn something from it that will help the next person.”

Today, transplants of the cornea — the clear tissue in front of the eye — are common to treat certain types of vision loss. But transplanting the whole eye — the eyeball, its blood supply and the critical optic nerve that must connect it to the brain — is considered a moonshot in the quest to cure blindness.
Whatever happens next, James' surgery offers scientists an unprecedented window into how the human eye tries to heal.
“We’re not claiming that we are going to restore sight,” said Dr. Eduardo Rodriguez, NYU's plastic surgery chief, who led the transplant. “But there’s no doubt in my mind we are one step closer.”
Some specialists had feared the eye would quickly shrivel like a raisin. Instead, when Rodriguez propped open James’ left eyelid last month, the donated hazel-colored eye was as plump and full of fluid as his own blue eye. Doctors see good blood flow and no sign of rejection.
Now researchers have begun analyzing scans of James’ brain that detected some puzzling signals from that all-important but injured optic nerve.
One scientist who has long studied how to make eye transplants a reality called the surgery exciting.
“It’s an amazing validation” of animal experiments that have kept transplanted eyes alive, said Dr. Jeffrey Goldberg, chair of ophthalmology at Stanford University.

The hurdle is how to regrow the optic nerve, although animal studies are making strides, Goldberg added. He praised the NYU team’s “audacity” in even aiming for optic nerve repair and hopes the transplant will spur more research.
“We’re really on the precipice of being able to do this,” Goldberg said.
James was working for a power line company in June 2021 when he was shocked by a live wire. He nearly died. Ultimately he lost his left arm, requiring a prosthetic. His damaged left eye was so painful it had to be removed. Multiple reconstructive surgeries couldn’t repair extensive facial injuries including his missing nose and lips.
James pushed through physical therapy until he was strong enough to escort his daughter Allie to a high school homecoming ceremony, wearing a face mask and eye patch. Still he required breathing and feeding tubes, and longed to smell, taste and eat solid food again.
“In his mind and his heart, it’s him — so I didn’t care that, you know, he didn’t have a nose. But I did care that it bothered him,” said his wife, Meagan James.
Face transplants remain rare and risky. James’ is only the 19th in the U.S., the fifth Rodriguez has performed. The eye experiment added even more complexity. But James figured he'd be no worse off if the donated eye failed.
Three months after James was placed on the national transplant waiting list, a matching donor was found. Kidneys, a liver and pancreas from the donor, a man in his 30s, saved three other people.
During James' 21-hour operation, surgeons added another experimental twist: When they spliced together the donated optic nerve to what remained of James’ original, they injected special stem cells from the donor in hopes of spurring its repair.
Last month, tingles heralded healing facial nerves. James can't yet open the eyelid, and wears a patch to protect it. But as Rodriguez pushed on the closed eye, James felt sensation — although on his nose rather than his eyelid, presumably until slow-growing nerves get reoriented. The surgeon also detected subtle movements beginning in muscles around the eye.

Then came a closer look. NYU ophthalmologist Dr. Vaidehi Dedania ran a battery of tests. She found expected damage in the light-sensing retina in the back of the eye. But she said it appears to have enough special cells called photoreceptors to do the job of converting light to electrical signals, one step in creating vision.
Normally, the optic nerve then would send those signals to the brain to be interpreted. James’ optic nerve clearly hasn't healed. Yet when light was flashed into the donated eye during an MRI, the scan recorded some sort of brain signaling.
That both excited and baffled researchers, although it wasn’t the right type for vision and may simply be a fluke, cautioned Dr. Steven Galetta, NYU’s neurology chair. Only time and more study may tell.
Still, the surgery marks “a technical tour de force,” said Dr. David Klassen, chief medical officer of the United Network for Organ Sharing, which runs the nation’s transplant system. "You can learn a tremendous amount from a single transplant” that could propel the field.
As for James, “we’re just taking it one day at a time,” he said.

Docs say Zuckerberg 'rejected' proposals to improve teen mental health on Facebook, Instagram
Meta CEO Mark Zuckerberg "personally rejected" proposals aimed at improving the mental health and wellbeing of teenagers on Facebook and Instagram, internal communications shared as part of an ongoing lawsuit have revealed, reports CNN.
According to the unsealed communications, Zuckerberg overruled senior executives, including Instagram CEO Adam Mosseri and President of Global Affairs Nick Clegg, who advocated for increased measures to protect more than 30 million teens using Instagram in the United States.

One notable rejection involved a 2019 proposal to disable Instagram's "beauty filters," which digitally alter users' appearances and have been linked to promoting unrealistic body image expectations, negatively impacting teens' mental health, said the report.
Despite broad support from top executives, Zuckerberg insisted that there was a "demand" for the filters and claimed he had seen "no data" indicating harm.

The lawsuit revealed internal tensions within Meta, with executives expressing concerns about the lack of investment in well-being initiatives. Instagram's policy chief, Karina Newton, and Meta's vice president of product design, Margaret Gould Stewart, had recommended disabling beauty filters based on advice from academics and external advisors. However, after Chief Technology Officer Andrew Bosworth brought the matter to Zuckerberg's attention, the proposal was rejected.
The newly unveiled documents also accused Meta of exploiting the psychology of adolescent brains and claimed that Zuckerberg personally set goals for increasing user engagement on Instagram, potentially prioritising profits over user wellbeing.

In response, Meta spokesman Andy Stone defended the company, emphasising that they have a robust central team overseeing youth well-being efforts and have implemented various tools to support teens and families. Stone also stated that Meta banned filters promoting cosmetic surgery, changes in skin colour, or extreme weight loss.

Industrial robot crushes worker to death
An industrial robot crushed a worker to death at a vegetable packaging plant in South Korea, police said Thursday, as they investigate whether the machine was unsafe or had potential defects.
According to police officials in the southern county of Goseong, the man died of head and chest injuries Tuesday after he was grabbed and pressed against a conveyor belt by the machine’s robotic arms. Police did not release his name but said the man was an employee of a company that installs industrial robots and was sent to the plant to examine whether the machine was working properly.
Read: Can Earthquakes Really be Predicted?
The machine was one of two pick-and-place robots used at the facility that packages bell peppers and other vegetables exported to other Asian countries, police said. Such machines are common in South Korea's agricultural communities.
“It wasn’t an advanced, artificial intelligence-powered robot, but a machine that simply picks up boxes and puts them on pallets,” said Kang Jin-gi, who heads the investigations department at Gosong Police Station. He said the police were working with related agencies to determine whether the machine had technical defects or safety issues.
Another police official, who did not want to be named because he wasn’t authorized to talk to reporters, said police were also looking into the possibility of human error. The robot’s sensors are designed to identify boxes, and security camera footage indicated the man had moved near the robot with a box in his hands, which likely triggered the machine’s reaction, the official said.

“It’s clearly not a case where a robot confused a human with a box – this wasn’t a very sophisticated machine,” he said.
South Korea has had other safety accidents involving industrial robots in recent years. In March, a manufacturing robot crushed and seriously injured a worker who was examining the machine at an auto parts factory in Gunsan. Last year, a robot installed near a conveyor belt fatally crushed a worker at a milk factory in Pyeongtaek.

Google packs more artificial intelligence into new Pixel phones
Google on Wednesday unveiled a next-generation Pixel smartphones lineup that will be infused with more artificial intelligence tools capable of writing captions about photos that can also be altered by the technology.
The injection of more artificial intelligence, or AI, into Google’s products marks another step toward bringing more of the technology into the mainstream – a push company executives signaled they were embarking upon during their annual developer’s conference five months ago.
Read: Google brings its AI chatbot Bard into its inner circle, opening door to Gmail, Maps, YouTube
“Our focus is on making AI more helpful for everyone in a way that is bold and responsible,” Rick Osterloh, Google’s senior vice president of devices and services, said during Wednesday's event held in New York. As if to leave no doubt about Google’s current priorities, Osterloh described the new Pixel 8 and Pixel 8 Pro phones as a conduit for having “AI in your hand.”
The next moves will include allowing the 7-year-old Google Assistant to tap into the company’s recently hatched AI chatbot, Bard, to perform tasks. The expanded access to Bard comes just two weeks after Google began connecting the AI chatbot to the company's other popular service such as Gmail, Maps and YouTube.
Google is leaving it up to each user to decide whether to allow Bard to interact with its other services, an effort to address worries about AI sifting through potentially sensitive information as it seeks to learn more about language and people.
Read: It's Google versus the US in the biggest antitrust trial in decades
One of the new tricks that the Bard-backed assistant is supposed to be able to do is scan a photo taken on a phone powered by Google’s Android software and generate a pithy caption suitable for posting on social media. As Google has been doing with most of its AI gambits, the Bard-backed Google Assistant initially will only be available to a test audience before it is gradually offered on an opt-in basis to more owners of the latest Pixels.
As has become common across the industry, most of the other technology in the Pixel 8 and Pixel 8 Pro phones unveiled Wednesday will be similar to what has already been available in last year’s models.
One of the main selling points of the new phones will be improved cameras, including more AI-empowered editing tools that will mostly be available on the Pixel 8 Pro. The AI features will be able to spruce up photos, zoom into certain parts of images, substitute faces taken from other pictures in group shots and erase objects and people from images.
Read: Fair Technology launches ‘Hyundai Exchange Program’
Google is counting on the new AI twists added to this year’s lineup to be enough to justify a price increase — with the starting prices for both the Pixel 8 and Pixel 8 Pro increasing by $100 over last year’s comparable models.
That will result in the Pixel 8 selling for $700 and the Pixel 8 Pro for $1,000 when they go on sale in stores next week. Apple also raised the starting price of its top-end iPhone by $100 when its latest models came out last month, signaling inflationary pressures are starting to drive up the costs of devices that have become essential pieces of modern life.
The Pixel 8 Pro will also be able to take people's temperatures — an addition that could be a drawing card in a post-pandemic era as various strains of COVID evolve. But Google is still trying to get regulatory approval to enable that capability in the U.S. A 2020 phone, the Honor Play 4 Pro made my Huawei, also was able to screen for fevers, so Google isn’t breaking totally new ground.
Despite generally getting positive reviews, the Pixel phones have barely made a dent in a market dominated by Samsung and Apple since Google began making the devices seven years ago. But they have been gaining slightly more traction in recent years, with Pixel’s share of the high-end smartphone market now hovering around 4% from less than 1% three years ago, according to the research firm International Data Corp.

Google can afford to make a phone that doesn’t generate huge sales because it brings in more than $200 billion annually from a digital ad network that’s anchored by its dominant search engine. A big chunk of the ad revenue flows from the billions of dollars that Google pays annually to lock in its search engine as the main gateway to the internet on the iPhone and Samsung’s Galaxy lineup.
The agreements that have given Google’s search engine a lucrative position on phones and computers are the focal point of an ongoing antitrust trial in Washington, where the U.S. Justice Department is trying to prove its allegations that Google has been abusing its power to stifle competition and innovation.

Can Earthquakes Really be Predicted?
The history of earthquakes is nothing less than terrifying. Whether it’s the 1556 Shaanxi earthquake or something as recent as the 2023 Turkey–Syria earthquake, every major earthquake in the world involves destruction and death. For centuries, scientists, geologists, saints, and seers alike have searched for answers to one inevitable question: Can earthquakes be predicted? Let’s try to find out.
Myths about Earthquakes and Predicting Them
The phenomenon of earthquakes has long been attributed to mythical and otherworldly happenings. Thousands of years ago, the occurrence of an earthquake not only brought destruction but also paved the way for the fear of the unknown and faith in supernatural power.
The concept of an earthquake is often attributed to Poseidon, the god of the sea in Greek mythology. It is said that Poseidon uses his trident to shake the earth which causes earthquakes. Similar stories are found in Japanese mythology where the giant catfish Namazu causes earthquakes. According to Mongolian mythology, the earth is placed on the back of a giant frog. When the frog stumbles, it causes earthquakes.

But beyond the myths, there are also some common misconceptions about earthquake predictions. Unlike the myths, these aren’t quite outlandish and are often passed on as hard facts. Some of the common misconceptions regarding earthquake prediction include:
- Animals can predict earthquake - There are always advanced signs of earthquakes - Earthquake is preceded by sudden weather change - Planetary alignment influences earthquake - Increased seismic activity is a precursor for a large earthquake - A series of small earthquakes deters the chance of a large earthquake in a region.
Unfortunately, none of these concepts are true. There is no set pattern to earthquakes and neither does it have any identifiable precursors. And that brings us to the all-important question.
