WASHINGTON — A ancient giant snake in India might have been longer than a school bus and weighed a ton, researchers reported Thursday.

Fossils found near a coal mine revealed a snake that stretched an estimated 11 meters to 15 meters. It’s comparable to the largest known snake at about 13 meters that once lived in what is now Colombia.

The largest living snake today is Asia’s reticulated python at 10 meters.

The newly discovered behemoth lived 47 million years ago in western India’s swampy evergreen forests. It could have weighed up to 1,000 kilograms, researchers said in the journal Scientific Reports.

They gave it the name Vasuki indicus after “the mythical snake king Vasuki, who wraps around the neck of the Hindu deity Shiva,” said Debajit Datta, a study co-author at the Indian Institute of Technology Roorkee.

This monster snake wasn’t especially swift to strike.

“Considering its large size, Vasuki was a slow-moving ambush predator that would subdue its prey through constriction,” Datta said in an email.

Fragments of the snake’s backbone were discovered in 2005 by co-author Sunil Bajpai, based at the same institute, near Kutch, Gujarat, in western India. The researchers compared more than 20 fossil vertebrae to skeletons of living snakes to estimate size.

While it’s not clear exactly what Vasuki ate, other fossils found nearby reveal that the snake lived in swampy areas alongside catfish, turtles, crocodiles and primitive whales, which may have been its prey, Datta said.

The other extinct giant snake, Titanoboa, was discovered in Colombia and is estimated to have lived around 60 million years ago.

What these two monster snakes have in common is that they lived during periods of exceptionally warm global climates, said Jason Head, a Cambridge University paleontologist who was not involved in the study.

“These snakes are giant cold-blooded animals,” he said. “A snake requires higher temperatures” to grow into large sizes.

So does that mean that global warming will bring back monster-sized snakes?

In theory, it’s possible. But the climate is now warming too quickly for snakes to evolve again to be giants, he said.

vancouver, british columbia — A new, digestible mini-robotic camera, about the size of a multivitamin pill, was demonstrated at the annual TED Conference in Vancouver. The remote-controlled device can eliminate invasive medical procedures.

With current technology, exploration of the digestive tract involves going through the highly invasive procedure of an endoscopy, in which a camera at the end of a cord is inserted down the throat and into a medicated patient’s stomach.

But the robotic pill, developed by Endiatx in Hayward, California, is designed to be the first motorized replacement of the procedure. A patient fasts for a day, then swallows the PillBot with lots of water. The PillBot, acting like a miniature submarine, is piloted in the body by a wireless remote control. After the exam, it then flushes out of the human body naturally.

For Dr. Vivek Kumbhari, co-founder of the company and professor of medicine and chairman of gastroenterology and hepatology at the Mayo Clinic, it is the latest step toward his goal of democratizing previously complex medicine.

If procedure-based diagnostics can be moved from a hospital to a home, “then I think we have achieved that goal,” he said. The new setting would require fewer medical staff personnel and no anesthesia, producing “a safer, more comfortable approach.”

Kumbhari said this technology also makes medicine more efficient, allowing people to get care earlier in the course of an illness.

For co-founder Alex Luebke, the micro-robotic pill can be transformative for rural areas around the world where there is limited access to medical facilities.

“Especially in developing countries, there is no access” to complex medical procedures, he said. “So being able to have the technology, gather all that information and provide you the solution, even in remote areas – that’s the way to do it.”

Luebke said if internet access is not immediately available, information from the PillBot can be transmitted later.

The duo are also utilizing artificial intelligence to provide the initial diagnosis, with a medical doctor later developing a treatment plan.

Joel Bervell is known to his million social media followers as the “Medical Mythbuster” and is a fourth-year medical student at Washington State University. He said the strength of this type of technology is how it can be easily used in remote and rural communities.

Many patients “travel hundreds of miles, literally, for their appointment. Use of a pill that would not require a visit to a physician “would be life-changing for them.” 

The micro-robotic pill is undergoing trials and will soon be in front of the U.S. Food and Drug Administration for approval, which developers expect to have in 2025. It’s expected that the pill would then be widely available in 2026.

Kumbhari hopes the technology can be expanded to the bowels, vascular system, heart, liver, brain and other parts of the body. Eventually, he hopes, this will allow hospitals to be left for more urgent medical care and surgeries.

HONG KONG — Apple said it had removed Meta’s WhatsApp messaging app and its Threads social media app from the App Store in China to comply with orders from Chinese authorities.

The apps were removed from the store Friday after Chinese officials cited unspecified national security concerns.

Their removal comes amid elevated tensions between the U.S. and China over trade, technology and national security.

The U.S. has threatened to ban TikTok over national security concerns. But while TikTok, owned by Chinese technology firm ByteDance, is used by millions in the U.S., apps like WhatsApp and Threads are not commonly used in China.

Instead, the messaging app WeChat, owned by Chinese company Tencent, reigns supreme.

Other Meta apps, including Facebook, Instagram and Messenger remained available for download, although use of such foreign apps is blocked in China due to its “Great Firewall” network of filters that restrict use of foreign websites such as Google and Facebook.

“The Cyberspace Administration of China ordered the removal of these apps from the China storefront based on their national security concerns,” Apple said in a statement.

“We are obligated to follow the laws in the countries where we operate, even when we disagree,” Apple said.

A spokesperson for Meta referred to “Apple for comment.”

Apple, previously the world’s top smartphone maker, recently lost the top spot to Korean rival Samsung Electronics. The U.S. firm has run into headwinds in China, one of its top three markets, with sales slumping after Chinese government agencies and employees of state-owned companies were ordered not to bring Apple devices to work.

Apple has been diversifying its manufacturing bases outside China.

Its CEO Tim Cook has been visiting Southeast Asia this week, traveling to Hanoi and Jakarta before wrapping up his travels in Singapore. On Friday he met with Singapore’s deputy prime minister, Lawrence Wong, where they “discussed the partnership between Singapore and Apple, and Apple’s continued commitment to doing business in Singapore.”

Apple pledged to invest over $250 million to expand its campus in the city-state.

Earlier this week, Cook met with Vietnamese Prime Minister Pham Minh Chinh in Hanoi, pledging to increase spending on Vietnamese suppliers.

He also met with Indonesian President Joko Widodo. Cook later told reporters that they talked about Widodo’s desire to promote manufacturing in Indonesia, and said that this was something that Apple would “look at.”
