An international scientific team of researchers from US, Britain and Tanzania found evidence that claims that chimpanzees' characteristics have been stable over long periods of time. They stated in their study, which was published in the journal "Scientific Data," the history of the sequence of their tests and their results.

Part of the team was Jean Goodall, who is among the world's most famous researcher in this field and have been working for nearly half a century studying chimpanzees in the natural habitat of the National Park in Gombe, Tanzania.

Some researchers have in the past examined thoroughly the chimpanzees and their characteristics in the region, but some scientists in the world have avoided such studies and considered them unscientific. However, researcher Goodall was the first to assume the existence of a unique personality of the chimpanzees.

Her international team conducted tests to classify each chimpanzee's behavior and personality by assessing degree of aggression and other traits. The research led to the conclusion that chimpanzees have personality characteristics.

After analyzing the archives of studies on chimpanzees at the end of the 1970s, researchers conducted almost identical tests to verify the continuity of personality characteristics of the same individuals. Other tests were conducted on other chimpanzees living in wildlife sites.

The researchers compared their findings with previous historical ones and found a remarkable continuation of the same personality characteristics of chimpanzees that are under the study.

Although they noted slight changes in the age and "wisdom" of these individuals, they observed that chimpanzee traits remained the same, as with human personality and characteristics.

For one month starting on Saturday, Olympic spectators keen for a side trip to a UNESCO World Heritage Site can use Uber to reserve a ride on a snowmobile along the snow-covered road to the base of the Three Peaks of Lavaredo.

The dramatic, jagged limestone pinnacles stand just 23 kilometers (14.3 miles) from the Cortina venues where athletes are competing in the 2026 Winter Olympics and Paralympics.

One of the Olympic torchbearers, Giulia Baffetti, runs snowmobiling tours through Cortina-based winter activities outfit Snowdreamers. The company partnered with Uber, the official ride-hailing sponsor for the Games, to offer free tours on the weekends in February to people in town.

"Uber Snowmobile" tours, which can only be booked through Uber, include a ride in an Uber transfer bus for up to eight people from Cortina to the spot where riders mount their snowmobiles for departure. Tourgoers then follow the instructor, who leads the line of snowmobiles.

The first slots offered went fast, but Uber spokesperson Caspar Nixon said Friday that it planned to add more.

The three peaks are a magical place, Baffetti said, and this is a way for more people to experience it. Hikers and climbers flock there in the warmer months. In the winter, it’s a prime spot for cross-country skiing, snowshoeing and sledding. Snowmobiling is allowed in a limited area in order to protect the environment.

"We want to give an experience to the tourists, so they can feel the mountains in a different way," she said.

The Associated Press took the one-hour tour on Thursday, ahead of the Saturday launch, along with one other person. Helmets are essential, while heated handgrips are a most welcome feature. And that red button? Passengers can push it to stop the snowmobile if it veers off course or they feel unsafe.

The adrenaline-filled ride reaches speeds up to 40 kph (25 mph) when zooming past snow-covered trees, and drivers are instructed to slow when coming upon cross-country skiers and sledders. Deer and wolves are sometimes seen along the 7-kilometer (4.3-mile) route up to the base of the peaks.

Also visible on Thursday was the southernmost of the three Lavaredo peaks, rising sharply out of the fog. While the Dolomites are breathtaking from Cortina — and on Friday, the sun shone and the view was clear from town — they are even more impressive up close.

The route back includes a short loop around Lake Antorno. Before traversing all the ups and downs, the snowmobile instructor leading the tour offers a reminder about that red button.

Saher Deeb, an Israeli tourist, was along for the ride Thursday, one day after his 29th birthday. It was his first time on a snowmobile, and he was all smiles as he climbed off at the end.

"It was perfect," he said.

Two French adventurers reached the end of an epic walk from France to Shanghai on Saturday, after nearly a year and a half crossing 16 countries almost entirely on foot.

Loic Voisot and Benjamin Humblot embraced as they stood by the river on the Bund promenade, the financial hub's distinctive skyline glittering in the background.

Voisot and Humblot set off from Annecy in September 2024.

"We were thinking about this moment almost every day for more than a year now, so it's a really strong feeling," Humblot said of reaching their destination.

Hanging out after work one day, the two friends realized they both yearned for a "great adventure".

They wanted to visit China -- but without flying, which they believe is too harmful to the environment.

A plan to set out on foot was hatched, and except for a stretch in Russia which was done by bus for safety reasons, 518 days and around 12,850 kilometers (7,980 miles) later they took the last steps to completing it.

Around 50 people gathered at the start point for the last 10km stretch of their odyssey, many local people who have been following them on social media.

Along the way their numbers swelled, as media, French residents of Shanghai and others joined.

"If your dreams are crazy, just take it step by step and sometimes you will not succeed, but sometimes you will," said Voisot.

Asked what he would do first now the walk was over, he joked: "Sleep a lot!"

A soft layer of white snow blankets the grounds of the Chicago Botanic Garden. The air is chilly, the sky gray.

Inside, however, the air is warm and lights illuminate more than 10,000 vividly colored orchids. Staff members move in and out of greenhouses, preparing to open the garden’s 12th annual Orchid Show on Saturday.

This year’s theme is “Feelin’ Groovy" with several installations calling back to the 1970s, including a yellow Volkswagen Beetle filled with orchids.

“It’s just a really great way to get out of the winter cold and come into our greenhouses,” said Jodi Zombolo, associate vice president of visitor events and programs. “I think people are really looking for something to kind of bring happiness and something that they will enjoy and find whimsy in.”

The orchid family is one of the largest in the plant world and some of the species in the show are rare, exhibits horticulturist Jason Toth said. One example is the Angraecum sesquipedale, also known as Darwin’s orchid, on display in the west gallery.

Toth said the orchid led Darwin to correctly conclude that pollinators have adapted in order to reach down the flower's very long end.

"It has a great story and it’s quite remarkable-looking,” said Toth.

Elsewhere, massive, gnarly roots dangle from purple, pink and yellow Vanda orchids in the south greenhouse. These epiphytic orchids grow on the surface of trees instead of in soil.

“I think everyone’s tired of the winter,” said Toth. “So having some kind of flower show at this point is what we’re all craving. And 'Orchids' fits the bill.”

The show is expected to draw 85,000 visitors this year.
