A lecture hall full of first-year veterinary students in Hungary eagerly took their places for the first animal anatomy lesson of their academic careers, when two full-grown horses clopped inside and joined the class.

The rector at the University of Veterinary Medicine in Budapest, Dr. Péter Sótonyi, coaxed one of the animals onto a riser at the front of the hall and used a stick of chalk to draw onto the horse — from head to hooves — where its bones, organs and muscles could be found inside.

"This is their very first lesson, and the first time should be with a living animal," Sótonyi said of his students. "They shouldn’t first meet with a carcass, because they want to heal animals. They want to make animals better."

Sótonyi has used this unique method for introducing students to animal anatomy for around 25 years, and is convinced it helps them engage more directly with the subject matter than studying solely through books, charts and models.

Horses, he said, which are "particularly intelligent and honorable animals," are especially suited to the task.

"It’s a big animal and a lot can be demonstrated on it, and people are so amazed that the horse comes into the classroom and climbs up on the podium. This immediately gives the students a lot of motivation," he said.

The horses, provided to the university each year by the Budapest Police, stood calmly throughout the lecture, encouraged by occasional treats of sugar cubes.

In addition to marking the animal's body with chalk and colorful oil pencils, Sótonyi held up pieces from a model horse skeleton to their corresponding locations to provide a clearer visual representation of the horse's anatomy.

About halfway through the hourlong lesson, Sótonyi demonstrated the oral structure of one of the animals, reaching his hand inside its mouth to grasp its long tongue — and getting a gentle nip from the horse in return.

"What's wrong with you today?" he asked the horse to laughter from the students, many of whom stood up for a better view and snapped pictures with their phones.

Following the lecture, there were no long faces or neigh-sayers, but a room of excited future veterinarians. Noémi Tamaska, 19, said that she thought the lecture with live horses was useful for future retention of the information.

"It meant a lot to me that we could see on a living animal how a skeletal system is built," she said. "I think it’s easier to imagine, especially for visually-oriented people."

Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

German scientists claim to have “rejuvenated” human eggs for the first time in an advance that they predict could revolutionize IVF success rates for older women.

The groundbreaking research suggests that an age-related defect that causes genetic errors in embryos could be reversed by supplementing eggs with a crucial protein, according to The Guardian.

When eggs donated by fertility patients were given microinjections of the protein, they were almost half as likely to show the defect compared with untreated eggs.

If confirmed in more extensive trials, the approach has the potential to improve egg quality, which is the primary cause of IVF failure and miscarriage in older women.

The decline in egg quality is the main reason IVF success rates drop steeply with female age and is why the risk of chromosome disorders such as Down’s syndrome increases with maternal age.

“Overall we can nearly halve the number of eggs with [abnormal] chromosomes. That’s a very prominent improvement,” said Prof Melina Schuh, a director at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and a co-founder of Ovo Labs, which is aiming to commercialize the technique.

“Most women in their early 40s do have eggs, but nearly all of the eggs have incorrect chromosome numbers,” added Schuh, whose lab has been investigating egg biology for the past two decades. “This was the motivation for wanting to address this problem.”

The latest approach targets a vulnerability in eggs linked to a process called meiosis, in which sex cells (eggs or sperm) jettison half their genetic material so they can join together to make an embryo.

In eggs, this requires 23 pairs of X-shaped chromosomes to align along a single axis in the cell. On fertilization, the cell divides causing the chromosome pairs to be – ideally – neatly snapped down their centers to create a cell with precisely 23 single chromosomes from the mother, the rest being delivered by the sperm.

However, in older eggs the chromosome pairs tend to loosen at their midpoint, becoming slightly unstuck or detaching entirely before fertilization.

In this scenario, the X-shaped structures fail to line up properly and move around chaotically in the cell, so when the cell divides they are not snapped symmetrically.

This results in an embryo with too many or too few chromosomes.

Schuh and colleagues previously found that a protein, Shugoshin 1, which appears to act as a glue for the chromosome pairs, declines with age. In the latest experiments in mouse and human eggs, they found that microinjections of Shugoshin 1 appeared to reverse the problem of chromosome pairs separating prematurely.

Using eggs donated by patients at the Bourn Hall fertility clinic in Cambridge, they found that the number showing the defect decreased from 53% in control eggs to 29% in treated eggs. When they looked only at eggs from women over 35 years of age, a similar trend was seen (65% compared with 44%), although this result was not statistically significant, which the scientists said was probably due to them only having treated nine eggs in this age range.

Dr Agata Zielinska, a co-founder and co-CEO of Ovo Labs, said: “Currently, when it comes to female factor infertility, the only solution that’s available to most patients is trying IVF multiple times so that, cumulatively, your likelihood of success increases. What we envision is that many more women would be able to conceive within a single IVF cycle.”

The findings will be presented at the British Fertility Conference in Edinburgh on Friday and have been published as a preprint paper on the Biorxiv website.

Swiss author Erich von Daeniken, who helped popularize the idea that astronauts from outer space visited Earth ​to help lay the foundations for human civilization, has died aged 90.

Swiss media including national broadcaster SRF reported his death, and a note on his website said it occurred on Saturday, The AP news reported.

Von Daeniken rose to ‌prominence with ‌his 1968 book "Chariots of ‌the ⁠Gods?" ​which posited ‌that structures such as the pyramids of Ancient Egypt, Britain's Stonehenge and Peru's Nazca lines were too advanced for their time, and needed outside help.

"In my opinion, ancient structures were made ⁠by humans, not by the extraterrestrials, but it was ‌the extraterrestrials who guided them, ‍who them, ‍who gave them the knowledge how to ‍do it," von Daeniken says in a video on his YouTube channel.

His theories were controversial with historians, scientists and fellow ​writers. But they were popular, and his books, which included "The Gods were ⁠Astronauts", sold nearly 70 million copies worldwide, appearing in more than 30 languages, SRF said.

Von Daeniken argued that ancient religions, myths and art contained evidence that millennia ago, the ancestors of modern humans had made contact with advanced extraterrestrial beings who appeared godlike to them and enabled them to progress.

One ‌day, von Daeniken said, those beings would return.

One of the largest and oldest icebergs ever tracked by scientists has turned blue and is “on the verge of complete disintegration,” NASA said on Thursday.

A23a, a massive wall of ice that was once twice the size of Rhode Island, is drenched in blue meltwater as it drifts in the South Atlantic off the eastern tip of South America, NASA said in a new release, according to CBS News.

A NASA satellite captured an image of the fading berg the day after Christmas, showing pools of blue meltwater on its surface. A day later, an astronaut aboard the International Space Station captured a photograph showing a closer view of the iceberg, with an even larger melt pool.

The satellite image suggests that the A23a has also “sprung a leak,” NASA said, as the weight of the water pooling at the top of the berg punched through the ice.

Scientists say all signs indicate the so-called “megaberg” could be just days or weeks from totally disintegrating as it rides currents that are pushing it toward even warmer waters.

Warmer air temperatures during this season could also speed up A23a's demise in an area that ice experts have dubbed a “graveyard” for icebergs.

“I certainly don't expect A-23A to last through the austral summer,” retired University of Maryland, Baltimore County scientist Chris Shuman said in a statement.

Blue and white linear patterns visible on A23a are likely related to striations, which are ridges that were scoured hundreds of years ago when the iceberg was part of the Antarctic bedrock, NASA said.

“The striations formed parallel to the direction of flow, which ultimately created subtle ridges and valleys on the top of the iceberg that now direct the flow of meltwater,” said Walt Meier, a senior research scientist at the National Snow & Ice Data Center.

The berg detached from Antarctica in 1986. It remained stuck for over 30 years before finally breaking free in 2020.

According to current estimates from the US National Ice Center, in early January 2026, the berg's area is 1,182 square kilometers -- still larger than New York City but a fraction of its initial size.
