This Teen Sensation Just Debuted as the Youngest Pro Cricket Player Ever

At just 14 years old, Vaibhav Suryavanshi has taken the Indian Premier League (IPL) by storm, making a memorable debut as its youngest player. The young left-hander from Rajasthan Royals made headlines when he smashed a massive six off the first ball he faced against the Lucknow Super Giants. Suryavanshi stepped in for captain Sanju Samson and quickly became an impact substitute during their chase of 181 runs. His impressive start included hitting Shardul Thakur over extra cover, leaving commentators like Australia’s Shane Watson in awe. “My word, what the hell was that?” Watson exclaimed during the broadcast. “Power to burn from the 14-year-old.” The teenager says he idolizes West Indian cricket legend Brian Lara and showcased his talent with two more sixes in a rapid 20-ball innings that yielded 34 runs. Despite his efforts and an 85-run opening stand with Yashasvi Jaiswal, Rajasthan Royals narrowly lost by two runs. Rajasthan’s spin bowling coach Sairaj Bahutule praised Suryavanshi's performance: “It was important to give him an opportunity... He batted beautifully.” Bahutule highlighted Suryavanshi's fearless approach and his ability to play shots all around the field. Suryavanshi first caught attention last November when he became the youngest player to secure a contract in the IPL at age 13, signing for $128,750 after a bidding war with Delhi Capitals. He debuted in India’s domestic Ranji Trophy competition at age 12 and has represented India’s Under-19 team against Australia. With fans eagerly watching his progress, Suryavanshi is poised to continue dazzling on cricket's big stage.

Paralympian Bride Stuns Wedding Guests by Walking Down Aisle Using Crutches

When Paralympian Suzanna Hext walked down the aisle this summer, her wedding guests couldn’t believe their eyes. The 37-year-old athlete from Cornwall, who has used a wheelchair since a horse-riding accident in 2012 left her paralysed, secretly trained for months to make the journey to the altar on crutches. Even her mother didn’t know what she was planning. “She almost passed out,” Hext said, laughing. “Everyone cheered when I reached the end — their reaction was incredible. It was a moment I will treasure forever.” Hext married her partner Gareth in July at the picturesque village church in St Just-in-Roseland. Six months pregnant at the time, she made the walk with her father by her side, using a combination of fixed-leg splints, crutches, and sheer upper-body strength. “As soon as we got engaged, I told Gareth I really wanted to be upright in some way whilst going down the aisle with my dad,” she said. “Having no feeling or functional movement from the waist down, I had to practise and practise, and I had quite a lot of help from the team at the hospital I attend.” The video she later shared on social media shows her determination paying off — each step greeted with gasps, applause, and tears. “It was the most perfect day,” Hext said. “I didn’t want it to end.” Born and raised in Cornwall, Hext’s life changed instantly when a horse she was training reared up and fell on top of her. The accident left her with severe injuries to her spine, head, pelvis, and shoulder. After years of recovery and rehabilitation, she found hope watching the 2012 Paralympics. That moment reignited her competitive spirit. Hext went on to win medals as a para equestrian before turning to swimming in 2017, where she quickly became a world champion. Now living in Calne, Wiltshire, Hext is also deaf and uses cochlear implants. Her hearing dog, Kimmy, whom she credits with “transforming” her life, had pride of place at the wedding. Between her athletic triumphs and her emotional walk down the aisle, Hext’s story is one of relentless courage — and love that quite literally lifted her to her feet.

Witness The Northern Lights In These 8 States Tonight

Skywatchers, get ready to look up this weekend as the northern lights are set to make another appearance. This stunning natural display, known as the aurora borealis, is caused by geomagnetic storms. These storms occur when charged particles from the sun interact with gases in Earth's atmosphere, creating waves of colorful light in the sky. The National Oceanic and Atmospheric Administration (NOAA) predicts that tonight’s auroral activity will have a Kp index of four on a scale from zero to nine. This means the lights might be visible as far south as southern Minnesota, near its border with Iowa. Recent solar activity, including minor geomagnetic storms and high-speed solar winds, has disrupted Earth's magnetic field, enhancing the visibility of this celestial event. According to NOAA's three-day forecast, auroral activity should continue through this evening and into the weekend. However, expect it to diminish by Sunday night with a Kp index dropping slightly over three for both Saturday and Sunday. Residents of Canada and Alaska will have prime viewing conditions after sunset. Meanwhile, states like Washington, Idaho, Montana, North Dakota, South Dakota, Wisconsin, Michigan, and Maine could also catch a glimpse of this spectacle. For those eager to see the northern lights firsthand, focus your attention on the northern horizon. The darker your surroundings are, the better your chances of seeing the vibrant colors emerge from what may initially seem like a faint glow. You don't need any sophisticated equipment; just find an open area away from city lights for optimal viewing. If you want to capture these magical moments on camera using your smartphone or more advanced photography gear like a DSLR or mirrorless camera is possible. Switch your smartphone to Night Mode before aiming at the sky. For those with professional cameras—use a tripod and shoot in manual mode for clear shots.

This Cat Mascot is Boosting Attendance at State University Football Games—Here's Why

At most college football games, mascots roar, charge, or soar — but at Bowling Green State University in Ohio, the star of the show purrs. Meet Pudge, a fluffy three-year-old Persian cat who has become the unlikeliest good-luck charm in college sports. Pudge attends every home game for the Bowling Green Falcons, padding his way into the hearts of players and fans alike. His calm presence and squishy face have turned him into a full-blown phenomenon. “There’s thousands of people there just to see a cat,” one player told CBS News. Pudge belongs to George Carlson, the team’s long snapper. Carlson first brought him into the locker room earlier this season when the team’s morale was low after a string of injuries. He figured they could all use a little comfort — and maybe some feline inspiration. “People love him, and I guess I can’t blame them, because I love him too,” Carlson said. For Carlson, Pudge isn’t just a mascot — he’s family. Last year, Carlson lost his mother, Cristen, to ovarian cancer. Living alone afterward, he said the quiet could be overwhelming. “It was very tough for me — especially living in a single apartment,” he said. “I could get really down. You’d spiral really easily. But the thing is, I could come home to this cat, who’s just funny looking, he’s slightly odd... It helped a lot.” That bond — and Carlson’s belief in what he calls “the healing power of the purr” — soon spread to the rest of the team. Pudge became part of the Falcons’ routine, showing up for games and media appearances and, in the process, winning over the entire community. Home game attendance has surged nearly 60 percent this season, according to the university — the biggest jump of any NCAA Division I football program in the country. And while Bowling Green’s players bring the grit on the field, it’s the long snapper and his long napper who’ve given everyone something extra to cheer for. As CBS News correspondent Steve Hartman put it, Pudge may not breathe fire or flex claws of steel — but he’s proof that sometimes, the fiercest mascot is the one with the softest touch.

Startup Transforms Grocery Shopping Into Adventure With 70% Discounts: 'A Fun Treasure Hunt'

Martie is shaking up the grocery game by rescuing food that would otherwise head to landfills. Started in 2021 by entrepreneurs Louise Fritjofsson and Kari Morris, this online grocery store offers pantry staples at a big discount while tackling food waste. Michelle Nadeau, Martie's head of marketing and communications, explained to The Cool Down that the company sells "shelf-stable groceries and household essentials at up to 70 percent off local grocery store prices." These items are delivered straight to customers' doors, making it convenient and budget-friendly. Before creating Martie, Fritjofsson and Morris had already made their mark with several healthy food ventures aimed at making nutritious options more affordable. However, they couldn't ignore the glaring inefficiencies in the US food system. With 30 to 40 percent of food going to waste annually and over 38 million people facing food insecurity, they saw an opportunity to address both issues simultaneously. Inspired by companies like Misfits Market and Imperfect Foods that sell discounted "ugly" produce, Martie buys salvage food and other household goods. According to Fritjofsson's chat with NBC Bay Area, these products range from overstocked items to those nearing best-by dates or undergoing packaging changes. Michelle told The Cool Down that Martie offers over 800 products across 14 categories including snacks, sweets, pantry staples, beverages, household items, and baby products. Well-known brands feature prominently on their platform: think KIND bars or Annie's pasta. Customers enjoy the freedom of no monthly memberships or subscriptions; they save an average of $54 per order or about $600 a year. Nearly half of Martie's shoppers return each month for more deals. Martie's impact isn't just on shoppers' wallets; it's also good for the planet. As Michelle noted in her email to TCD, "To date, Martie has saved over 2.3 million kilograms of food from going to waste," comparable to taking over 2,260 cars off the road annually. Initially serving only California with rescued foods, Martie moved its warehouse operations last year from California to Texas for wider reach across the country. This expansion helps them serve more customers nationwide while planning two new warehouses this year for even better service. Fritjofsson expressed excitement about offering surplus items at discounted rates nationwide when talking with TCD. She emphasized how selling surplus goods lets customers contribute positively toward environmental efforts simply by shopping smarter. By transforming unwanted inventory into valuable resources accessible online without breaking banks or harming nature further down our supply chain paths—Martie highlights how smart business practices can make a difference one purchase at a time.

A Capybara And a Monkey are Forming the Most Unlikely, And Adorable, Friendship At the Denver Zoo

At the Denver Zoo, an unlikely pair has captured hearts — a capybara and a howler monkey who’ve become best friends. Baya, a 16-year-old howler monkey, and Rebecca, a 6-year-old capybara, share an enclosure at the Colorado zoo. The two females have been spotted cuddling and resting together as the summer heat fades, their quiet bond melting hearts across social media. “Our howler monkey mom, Baya, and capybara, Rebecca, have been spotted sharing some seriously adorable cuddles,” the zoo wrote in a Facebook post. “You’re welcome for the cuteness overload.” In photos shared by the Denver Zoo, Baya can be seen hugging Rebecca’s midsection, pressing her face against her friend, and even perching on Rebecca’s back while they rest under a rock formation. “They are very content with each other,” said Jessica Newell, an assistant curator at the zoo. “Rebecca’s pretty calm, and Baya’s able to go to her for comfort and support.” Though both species come from South America, friendships like this are rare in the wild. Howler monkeys spend most of their time in trees, while capybaras prefer open grassy areas near water. But because their natural ranges overlap and both are gentle by nature, zoos often house them together. Newell said the match has worked out perfectly. “I think Baya just really finds Rebecca as a comforting friend,” she said. The Denver Zoo’s photos of the snuggly pair have since made the rounds online — proof that even across species, friendship can thrive.

Miami Nonprofit Provides Vital Health Care to Homeless, Easing Emergency Room Strain

When 58-year-old Jonas Richards lost his job as a truck driver, he also lost his home — and with it, his access to basic health care. For years, his high blood pressure and diabetes went untreated. “When you're homeless, it's not easy,” Richards said. “You find yourself hustling, trying to keep a little money in your pocket, trying to find something to eat.” That changed when a team from Miami Street Medicine pulled up outside a homeless shelter. Sitting on a curb, Richards received his first full check-up in years. “You get everything done right here very fast,” he said. “It was a big help.” Miami Street Medicine is a nonprofit that brings free, mobile health care directly to people living on the streets. It’s part of Dade County Street Response, a larger network that also includes a free clinic, a disaster relief team, and a mental health crisis line. The group’s founder, Dr. Dan Bergholz, says the idea is simple: meet people where they are — literally. “We’re out there to meet the needs of our patients,” he said. “If that’s a cough drop, we’ve got you. But really, the mission is so much greater. It’s showing that we care. So when that cough becomes pneumonia, they’ll let us listen to their lungs and maybe trust us to take them to the hospital.” Each team includes doctors, nurses, and volunteer medical students who conduct intake exams on tablet computers, track chronic conditions, and even connect patients with specialists in cardiology, neurology, and dermatology. Bergholz first started planning Miami Street Medicine about seven years ago, inspired by the growing “street medicine” movement — health care delivered outside traditional settings. “I moved down to Miami early and just started hitting the streets and chatting with people,” he said. “You could call it a needs assessment.” The group was just gaining momentum when COVID-19 hit. Rather than pause operations, Bergholz partnered with Dade County Street Response to expand services across Miami’s most underserved areas. “A sort of bigger vision emerged to fill the gaps in the local social safety net,” he said. That mission hasn’t been easy. Dr. Armen Henderson, who founded Dade County Street Response, said criminalization of homelessness makes it difficult to maintain consistent contact with patients. “The criminalization of homelessness has significantly impacted our patients’ ability to be in one place to get services,” he said. “If the majority of those patients are now ending up in jail, people are trying to figure out what places are police not harassing them.” He also pushed back against a common misconception that providing aid encourages homelessness. “The only thing that ends homelessness is easy access to housing,” Henderson said. “No one wants to be unsheltered. By offering services like this, we’re easing people’s suffering. When people come in here, they want to get off the street.” Doctors say they’ve seen homelessness rise across Miami as housing costs soar and wages stagnate. Dr. Inaki Bent, who oversees the street medicine teams, said the state’s immigration crackdown has also left many undocumented migrants jobless and living outdoors. “I see patients here who are no longer working,” Bent said. “They would prefer not to expose themselves to that risk.” Beyond the personal benefit to patients, treating people on the streets helps prevent expensive emergency room visits for conditions that could have been managed earlier. Bent shared one example: a man with seizures who couldn’t afford his prescription after leaving the hospital. Without intervention, he likely would have ended up back in the ER. Instead, Miami Street Medicine stepped in to pay for his medication. “So we’re able to fill that void and hopefully prevent a couple more admissions,” Bent said. “But we're also able to do a human service for him, for our fellow man, to provide him with the necessary health care so he can begin his path toward a productive life.” For Richards, that path began on a sidewalk — and with a doctor who came to him.

How Older Travelers are Fueling a Rise in Voluntourism, Embracing Impactful Holidays

Forget lounging poolside. More travellers are swapping sunbeds for shovels, choosing to spend their holidays rebuilding castles, planting trees or helping protect endangered wildlife. The trend of “voluntourism” — travel that combines leisure with volunteer work — is booming again. Once seen mainly as a rite of passage for students on gap years, it’s now attracting a growing number of older travellers looking for meaningful, hands-on experiences abroad. Voluntourism trips can last anywhere from a few weeks to several months. Travellers can work on conservation projects, join archaeological digs, or help with cultural and educational programmes. The goal is simple: see the world, and leave something positive behind. According to Grand View Research, volunteer tourism was worth about €725 million in 2023 and is expected to grow more than 6 percent a year through 2030. In Europe alone, the market is expanding by nearly 5 percent annually. The EU-funded European Solidarity Corps sends thousands of young people abroad each year for placements lasting from two weeks to a year. UNESCO’s World Heritage Volunteers initiative also runs camps in 41 countries, where participants help restore historic sites. And private travel operators have stepped in too, offering programmes that allow would-be volunteers to choose experiences in destinations that inspire them. Sarah Faith, senior values writer for Responsible Travel, says the company is seeing more interest in “citizen science” holidays — trips where travellers collect data for real-world research. “You might be entering details of the seabirds you spot on an Arctic expedition cruise into a research app,” she said. “Or collecting samples of freshwater for inclusion in a global databank of environmental DNA.” Faith says voluntourism isn’t new, but it’s evolving fast. “Gap year students have long signed up for projects like sea turtle conservation in Costa Rica or teaching in Southeast Asia,” she said. “But today, the options are far more diverse — from structured NGO programmes to short volunteer add-ons for regular holidays.” Young people remain a key part of the movement. The Dutch Centre for the Promotion of Imports estimates that Europeans aged 15 to 29 make up a large share of the 1.6 million people who volunteer abroad each year. Many are driven by a mix of adventure and purpose, often using the experience to build life or career skills. But the biggest new wave is coming from older travellers. The so-called “post-family” generation — those over 50 with more time and resources — is signing up in record numbers. This segment is forecast to grow nearly 8 percent annually through 2030. Travel firms have noticed. Organisations like Projects Abroad and GoEco now offer experiences tailored to mature volunteers, from childcare work in Nepal to conservation at a puma sanctuary in Argentina or elephant care projects in Botswana. Experts say voluntourism can be deeply rewarding — but it has to be done right. “Done well, voluntourism can be a lifeline for conservation and community projects,” Faith said. “But not all opportunities are created equal.” She advises travellers to ask questions before signing up. Check how funds are used, whether the organisation works with local NGOs, and if the project benefits the community long-term. Programmes that replace paid local jobs or encourage direct contact with wildlife should be avoided. Faith said Responsible Travel made a major shift more than a decade ago when it stopped selling orphanage volunteering holidays, after discovering that some children were being placed in institutions purely to attract volunteers. For those who still want to travel with purpose, there are other options. Citizen science trips and charity-run holidays, where profits directly support community projects, are growing fast. With new opportunities appearing around the world, voluntourism is no longer just for students or idealists — it’s for anyone who wants to explore the planet while doing something meaningful. As Faith put it, the key is simple: “Travel responsibly, and make sure your trip helps the people and places you visit.”

Here's Some Of the Happiest News You Missed This Week

The Best Positive News We’re Celebrating This Week A new Indigenous-led ocean reserve could be the largest of its kind The Melanesian Ocean Reserve is a step closer to becoming reality. Spanning over 6 million square kilometers across the Solomon Islands, Papua New Guinea, Vanuatu, and New Caledonia, it will be the first marine reserve governed entirely by Indigenous knowledge. While modern science and government resources will support it, Indigenous leadership will drive decision-making. That means protecting some of the most diverse marine life on the planet, with the same scale as the Amazon rainforest — but in the ocean. After global talks stalled, local leaders stepped up to tackle microplastics While the Global Plastic Treaty made little progress, individual cities and states are taking matters into their own hands to regulate and reduce microplastic pollution. An Australian woman donated thousands of hand-knit clothes to NICU babies When donations dried up during the pandemic, Kim Franks saw a Facebook post and started knitting. She hasn’t stopped. Living with a chronic condition that keeps her bedridden, Franks has found purpose in helping premature babies at John Hunter Children’s Hospital — estimating she’s made thousands of handmade clothes to keep them warm. A groundbreaking HIV prevention drug will soon cost just $40 a year The injectable drug lenacapavir, which reduces HIV transmission by over 99.9%, currently costs $28,000 a year in the US. But starting in 2027, generic versions will be made available in over 100 low- and middle-income countries — for just $40 annually. One health leader called it “a game-changer” in the fight to end HIV. A Jamaican student invented a door handle that disinfects itself Rayvon Stewart was volunteering at a hospital when he had the idea for Xermosol — a UV-powered door handle that sanitizes itself after every touch. It kills 99.9% of germs, doesn’t harm people or pets, and has already secured $200,000 in investments. Stewart’s invention earned him Jamaica’s Prime Minister’s National Youth Award. A North Carolina steakhouse became ‘autism-friendly’ Jim Gordon owns Peninsula Prime and has a daughter with autism. That inspired him to redesign the restaurant experience for autistic guests. The team now offers sensory kits, a menu with images to help nonspeaking guests order, and a quieter, more welcoming atmosphere. One family said they hadn’t gone out to eat in five years — until now. Maui’s second-largest tiny home village is now housing 900 residents Two years after devastating wildfires, hundreds of displaced Hawaiians have a place to call home. A new tiny home village is up and running, offering stability, dignity, and community. US foreign aid, despite its small share of income, is saving millions of lives In 2023, the US gave $62 billion in foreign aid — just 0.24% of its gross national income, yet enough to save an estimated 3.3 million lives. Most of that came from USAID, which previously supported HIV programs, vaccine delivery, malaria control, and more. Home bakers are making sure food banks get fresh bread, not just leftovers A nonprofit called Community Loaves, started during the pandemic, now has nearly 900 volunteer bakers across four US states. Together, they’ve donated more than 200,000 loaves of fresh, whole-grain bread to food banks — helping families access healthier options, especially as federal food aid continues to shrink. An island once covered in garbage is now a modern café A former “garbage island” has been transformed into a café built with recycled materials — including light fixtures made from plastic waste. Big trees in the Amazon are growing stronger, even with rising temperatures New research shows that the Amazon’s largest trees have grown thicker over the last 30 years, proving more resilient to drought and heat than expected. They also store more carbon, but scientists warn that deforestation could undo all this natural progress. After a school banned phones, students rediscovered the library In Kentucky, a phone ban during school hours led to something unexpected — students started reading more. At Pleasure Ridge Park High School, the library has already loaned out 1,200 books this year — nearly double what’s typical. Carbon emissions are dropping across every US state Between 2005 and 2023, per capita carbon emissions fell in all 50 US states. The biggest reason? Less coal, and more clean energy. More stories we're celebrating this week: • 12 popular podcasts united for a “Be Hope” takeover, proving that politics doesn’t have to be cynical. • Stand-up comics opened up about anxiety in a new film, “Anxiety Club,” with all profits supporting mental health. • A nonprofit has protected 1.5 million acres of ecosystems and is now restoring Greece’s seagrass, which stores 10x more carbon than rainforests. • A new tracking project is protecting flatback sea turtles, using motion sensors and GPS to study their behavior. • Wyoming’s building its first “third space” for teens, a free zone for kids to hang out and even earn money. • Brazil pledged $1 billion to a global forest fund, with support from France, China, and others. • China is turning old wind turbine blades into sand barriers to stop desertification. • Scientists found 8 new native bee species in Washington state. • Researchers created a solar-powered artificial plant that cleans radioactive soil by 95% in just 20 days. • A 9-year-old cancer patient got an early screening of “Wicked: For Good” and surprise messages from Ariana Grande and Cynthia Erivo. • Scientists developed a sunscreen made from pollen that protects coral reefs and works just as well as chemical options. • Tourism in Uganda is helping stop gorilla poaching, with locals turning from hunters into conservationists. • Hong Kong conservationists are helping endangered cockatoos by building new nesting spaces. • Vietnam will send its first transgender woman to Miss Universe in 2025. • Over 1,200 Portland residents joined a city cleanup, volunteering to make the city shine. • Volunteers sorted 50,000 pounds of marine debris in Hawaii to help scientists learn where the waste comes from. • In Ohio prisons, inmates are helping injured wildlife recover as part of a rehabilitation program. • Ecosia donated $100,000 to keep Jane Goodall’s reforestation project alive after USAID cuts. • Colorado named April 3 “Animals Matter Day” in honor of Goodall’s birthday. • Jane Goodall teamed up with a TikTok creator to talk about youth voting and climate action. • Mattel made a Jane Goodall Barbie from recycled ocean plastic. • Goodall wrote that youth are the key to saving the planet — and said hope is still alive. • Protesters worldwide called on banks to stop fueling climate change, saying it’s time to “Make Billionaires Pay.” • The Volo Kids Foundation has given 80,000+ children access to free sports. • Bolivia banned child marriage, becoming the latest country in Latin America to do so. • Researchers in Sweden found low-dose aspirin may help prevent colon cancer from returning after treatment.

New Evidence Suggests Saturn's Moon Enceladus Could Support Life

Scientists say Saturn’s icy moon Enceladus is looking more promising than ever as a place that could host life. A fresh analysis of data from NASA’s Cassini spacecraft has revealed new classes of organic molecules in the water vapor erupting from Enceladus’ south polar geysers. The findings, published this week in Nature Astronomy, suggest the moon’s hidden ocean has the right mix of ingredients for life to form — though no direct evidence of life has yet been found. “We have found several categories of organic – meaning primarily carbon-containing – molecules that span a range of structures and chemical properties,” said Nozair Khawaja, a planetary scientist at Freie Universität Berlin and lead author of the study. Cassini flew directly through the moon’s plumes during its closest pass in 2008, sampling tiny ice grains and gases ejected from Enceladus’ subsurface ocean. Scientists reexamined the data in detail, confirming earlier detections of amino acid precursors — the building blocks of proteins — and spotting new organic molecules never before identified. “Such compounds are believed to be intermediates in the synthesis of more complex molecules, which could be potentially biologically relevant,” Khawaja said. “It is important to note, however, that these molecules can be formed abiotically as well without any interaction with life on Earth.” Enceladus, a frozen moon only 504 kilometers across, is considered one of the best places in the solar system to search for alien life. Its buried ocean, sealed under 20 to 30 kilometers of ice, is thought to host hydrothermal vents that release hot, mineral-rich water — environments similar to those where life on Earth may have first emerged. “First of all, we did not find life on Enceladus and we did not find any biosignatures,” Khawaja stressed. “However, we have compelling evidence that all three keystones of habitability – liquid water, an energy source and essential elements and organics – exist on Enceladus.” The analysis relied on Cassini’s direct sampling of fresh ice grains, which had been ejected from the ocean only minutes earlier. Unlike particles in Saturn’s E ring, which are altered by long exposure to radiation, these grains preserved the chemistry of the moon’s hidden sea. The discovery adds momentum to future missions. The European Space Agency is planning to return to Enceladus to investigate its plumes with more advanced instruments than Cassini carried. “Enceladus is, and should be ranked, as the prime target to explore habitability and search whether there is life or not,” Khawaja said.
