Sunlight Could Help Desalinate Water Within Minutes, Say Scientists

In the 1990s, the Arab-American professor Omar Yaghi created a porous crystalline material known as the metal-organic framework (MOF) which has been used in many applications, including the desalination of seawater.

According to the latest issue of the Nature Sustainability journal, an Australian research team used MOF to produce a new material that can desalinate seawater within few minutes when combined with sunlight.

The currently used desalination techniques consume massive amounts of energy, however, the new method developed by researchers at the Monash University harnesses sunlight to purify water in few minutes using a process that is more efficient than existing techniques.

The Australian team created a new MOF which was partly made up of a material called MIL-53, already known for the way it reacts to water and carbon dioxide. This material can absorb salt from water in 30 minutes. After just four minutes of exposure to sunlight, the material releases all of the salt ions it's soaked up from the water, and is ready to be used again. Around 139.5 liters (nearly 37 gallons) of clean water can be produced per day from a kilogram of MOF material, based on early testing.

In a report published on Saturday by the Medical News Today website, chemical engineer Huanting Wang from Monash University said: "Thermal desalination processes by evaporation are energy-intensive, and other technologies, such as reverse osmosis, have a number of drawbacks, including high energy consumption and chemical usage in membrane cleaning and dechlorination. Sunlight is the most abundant and renewable source of energy on Earth."

"Our development of a new adsorbent-based desalination process through the use of sunlight for regeneration provides an energy-efficient and environmentally-sustainable solution for desalination," he explained.

Wang said the new affordable technique produce water that meets the WHO standards of water desalination and could help address the problem of around 785 million people who lack a clean source of drinking water globally within half an hour's walk of where they live.

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.
