If you like to stay hydrated no matter where you go, chances are you´ve got a reusable water bottle or two. Or 10. (The collectors know who they are.)

Whether you´re a tech enthusiast, fashion trendsetter, hiker, commuter or just an eco-conscious consumer, there´s a bottle out there for you. There are bottles that sterilize themselves. Bottles that remind you when to drink. Bottles designed for sustainability. And bottles transformed by a paintbox of colors and imagery into mini artworks.

Hydration´s become more than a necessity. It´s got a personality.

Kit Dillon, a writer for Wirecutter, says four things make a good water bottle: "It´s the right size. It´s leakproof. It feels good. It insulates well."

Which one works for you depends on what you use it for, he says. Eva Bleyer, who tests kitchen appliances for the Good Housekeeping Institute, agrees.

Some people go for a favorite sipping straw while others value a comfortable carrying handle. For collectors, social media feeds light up with the launch of new colors and patterns, The AP news reported.
"While I can confidently recommend which ones performed best in our tests, choosing the right water bottle is incredibly personal," she says.

It´s all a far cry from the mundane mugs of yesteryear.

An early maker of light, plastic water bottles was Nalge, in Rochester, New York, which found that the unbreakable containers it was making for science laboratories in the ´60s were being used by employees on backpacking trips. The Nalgene reusable water bottle soon went on the market.

Hundreds of plastic and bioplastic versions from various makers have been joined over the decades by stainless steel and aluminum versions, with as many iterations of the lids - straws, screw-ons, flip-ups.

The tech keeps evolving, says Bleyer. "I´ve seen and tested everything from filtering water bottles to the Air Up, which uses flavor pods to enhance the taste, as well as newer options that carbonate your water or track your sips."

Some examples:

Self-cleaning bottles could be helpful in countries or wilderness areas where water quality is questionable. Philips' GoZero UV Self-Cleaning Smart Water Bottle got top ratings in Men´s Health magazine´s testing lab for self-cleaning bottles. Its month-long battery life might make it useful for off-grid camping or trekking. LED technology automatically sanitizes the bottle every two hours, or whenever you push the cap button.

The LARQ PureVis 2 is another self-cleaning water bottle. The company says the plant-based filter in the lid removes chlorine, forever chemicals (PFAS) and bacteria. The bottle also tracks your consumption. It´s made it into the Museum of Modern Art´s design store and is part of their spring new product collection.

The HidrateSpark Pro comes with a Bluetooth tracker to keep you updated on consumption, based on your age, weight, activity level and other factors you code into the app.

Low tech but reliable: Wirecutter has put the Hydro Flask on their "best" list since they started testing water bottles in 2014, citing simple yet dependable features like good insulation, sturdy steel construction, wide or narrow mouth options, and dishwasher-cleanability.

New color and design drops generate the kind of buzz that fashion drops get. Owala´s FreeSip bottles usually go for about $25-$40, but limited-edition designs can sell in the $400 range. A Valentine´s Day pattern, and a St. Patrick´s Day pattern called "Clover the Rainbow" that was released on leap day 2024 (Feb. 29) are now on eBay for over $200.

S'well has collaborated with illustrator Steffi Lynn, known for her cheery, youthful prints and murals that feature upbeat messages like "What´s the Best That Could Happen?" and "Have a Nice Day," and also with Crayola for a series of bottles that look like giant crayons. New patterns for the brand include a deep, moody floral called Midnight Botanical.

S´well also offers customization, perhaps for an event, team or a gift for a special someone.

Italian company YouBottles did a collab with Banksy; the artist´s "Girl with Balloon" and "Flower Thrower" murals are a couple of the patterns.

Color trend giant Pantone has its own collection of BPA-free bottles in eight vibrant colors, including aubergine, red, yellow and greenery.

Snazzy carry bags for your water bottle include insulated ones that keep the drink cold or hot. PackIt has one with a crossbody strap in sturdy nylon. Versions come in sunflower or starry-night prints, and feature a phone pouch attachment.

WanderFull´s bag has made "Oprah´s Favorite Things" list twice. The bag, available in colorful puffer-coat fabric, comes with a nylon crossbody strap. There´s a vegan leather version as well, with an additional chain strap for dressier occasions.

The world's main coffee-growing regions are roasting under additional days of climate change-driven heat every year, threatening harvests and contributing to higher prices, researchers said Wednesday.

An analysis found that there were 47 extra days of harmful heat per year on average in 25 countries representing nearly all global coffee production between 2021 and 2025, according to independent research group Climate Central.

Brazil, Vietnam, Colombia, Ethiopia and Indonesia -- which supply 75 percent of the world's coffee -- experienced on average 57 additional days of temperatures exceeding the threshold of 30C.

"Climate change is coming for our coffee. Nearly every major coffee-producing country is now experiencing more days of extreme heat that can harm coffee plants, reduce yields, and affect quality," said Kristina Dahl, Climate Central's vice president for science.

"In time, these impacts may ripple outward from farms to consumers, right into the quality and cost of your daily brew," Dahl said in a statement.

US tariffs on imports from Brazil, which supplies a third of coffee consumed in the United States, contributed to higher prices this past year, Climate Central said.

But extreme weather in the world's coffee-growing regions is "at least partly to blame" for the recent surge in prices, it added.

Coffee cultivation needs optimal temperatures and rainfall to thrive.

Temperatures above 30C are "extremely harmful" to arabica coffee plants and "suboptimal" for the robusta variety, Climate Central said. Those two plant species produce the majority of the global coffee supply.

For its analysis, Climate Central estimated how many days each year would have stayed below 30C in a world without carbon pollution but instead exceeded that level in reality -- revealing the number of hot days added by climate change.

The last three years have been the hottest on record, according to climate monitors.


Dog Gives Olympics Organizers Paws for Thought

A dog decided he would bid for an unlikely Olympic medal on Wednesday as he joined the women's cross country team free sprint in the Milan-Cortina Games.

The dog ran onto the piste in Tesero in northern Italy and gamely, even without skis, ran behind two of the competitors, Greece's Konstantina Charalampidou and Tena Hadzic of Croatia.

He crossed the finishing line, his moment of glory curtailed as he was collared by the organizers and led away -- his owner no doubt will have a bone to pick with him when they are reunited.


Olives, Opera and a Climate-Neutral Goal: How a Mural in Greece Won ‘Best in the World’

Long known for its olives and seaside charm, the southern Greek city of Kalamata has found itself in the spotlight thanks to a towering mural that reimagines legendary soprano Maria Callas as an allegory for the city itself.

The massive artwork on the side of a prominent building in the city center has been named 2025’s “Best Mural of the World” by Street Art Cities, a global platform celebrating street art.

Residents of Kalamata, approximately 240 kilometers (150 miles) southwest of Athens, cultivate the world-renowned olives, figs and grapes that feature prominently on the mural.

That was precisely the point.

Vassilis Papaefstathiou, deputy mayor of strategic planning and climate neutrality, explained Kalamata is one of the few Greek cities with the ambitious goal of becoming climate-neutral by 2030. He and other city leaders wanted a way to make abstract concepts, including sustainable development, agri-food initiatives, and local economic growth, more tangible for the city’s nearly 73,000 residents.

That’s how the idea of a massive mural in a public space was born.

“We wanted it to reflect a very clear and distinct message of what sustainable development means for a regional city such as Kalamata,” Papaefstathiou said. “We wanted to create an image that combines the humble products of the land, such as olives and olive oil — which, let’s be honest, are famous all over the world and have put Kalamata on the map — with the high-level art.”

“By bringing together what is very elevated with ... the humbleness of the land, our aim was to empower the people and, in doing so, strengthen their identity. We want them to be proud to be Kalamatians.”

Southern Greece has faced heatwaves, droughts and wildfires in recent years, all of which affect the olive groves on which the region’s economy is hugely dependent.

The image chosen to represent the city was Maria Callas, widely hailed as one of the greatest opera singers of the 20th century and revered in Greece as a national cultural symbol. She may have been born in New York to Greek immigrant parents, but her father came from a village south of Kalamata. For locals, she is one of their own.

This connection is also reflected in practice: the alumni association at Kalamata’s music school is named for Callas, and the cultural center houses an exhibition dedicated to her, which includes letters from her personal archive.

Artist Kleomenis Kostopoulos, 52, said the mural “is not actually called ‘Maria Callas,’ but ‘Kalamata’ and my attempt was to paint Kalamata (the city) allegorically.”

Rather than portraying a stylized image of the diva, Kostopoulos said he aimed for a more grounded and human depiction. He incorporated elements that connect the people to their land: tree branches — which he considers the above-ground extension of roots — birds native to the area, and the well-known agricultural products.

“The dress I create on Maria Callas in ‘Kalamata’ is essentially all of this, all of this bloom, all of this fruition,” he said. “The blessed land that Kalamata itself has ... is where all of these elements of nature come from.”

Creating the mural was no small feat. Kostopoulos said it took around two weeks of actual work spread over a month due to bad weather. He primarily used brushes but also incorporated spray paint and a cherry-picker to reach all edges of the massive wall.

Papaefstathiou, the deputy mayor, said the mural has become a focal point.

“We believe this mural has helped us significantly in many ways, including in strengthening the city’s promotion as a tourist destination,” he said.

Beyond tourism, the mural has sparked conversations about art in public spaces. More building owners in Kalamata have already expressed interest in hosting murals.

“All of us — residents, and I personally — feel immense pride,” said tourism educator Dimitra Kourmouli.

Kostopoulos said he hopes the award will have a wider impact on the art community and make public art more visible in Greece.

“We see that such modern interventions in public space bring tremendous cultural, social, educational and economic benefits to a place,” he said. “These are good springboards to start nice conversations that I hope someday will happen in our country, as well.”
