Researchers issue warning as relentless droughts devastate global food supply: 'No country is immune'
Around the world, families are seeing higher food prices linked to more extreme weather, which is being driven by rising global temperatures. From Mexico City to Zimbabwe and the Amazon basin, experts warn that relentless drought is unraveling food systems that people rely on to survive.
In a new report, global experts call the findings "a blistering reminder" of what happens when record-breaking heat meets underprepared infrastructure and a warming planet.
What's happening?
As covered by Grist, a joint report from the U.S. National Drought Mitigation Center and the United Nations Convention to Combat Desertification documents what may be the most widespread food and water disruption in recent history.
In Zimbabwe, rivers have dried up, cattle have died, and child malnutrition has doubled. In Mexico City, a yearslong water crisis sent food prices skyrocketing, with cilantro reportedly rising 400% in price. And in the Amazon basin, water levels dropped so low that mass fish die-offs contaminated local drinking supplies, forcing residents to dig wells or wait for airlifted emergency aid.
These regional emergencies are already having ripple effects. The study found that the combined toll of extreme heat, El Niño, and inefficient water management has disrupted agricultural production across multiple continents, with experts warning the economic shock waves are far from over. "No country is immune when critical water-dependent systems start to collapse," said report co-author Cody Knutson.
Why are extreme droughts concerning?
When drought hits major food-producing regions, the results show up everywhere, from empty fields to inflated grocery prices. Millions are already facing food insecurity, and rising temperatures are likely to make these disasters more frequent and more intense.
The authors emphasize that these crises don't happen in isolation. Global food systems are interconnected, meaning a rice shortage in Vietnam or a failed corn harvest in Africa can push prices up for consumers worldwide. And that's before factoring in how water scarcity affects sanitation, public health, and entire ecosystems.
"Drought is not just a weather event," said NDMC Assistant Director Kelly Helm Smith. "It can be a social, economic, and environmental emergency."
What can I do to help?
While large-scale action is needed from governments and industries, everyday people can play a role too. Reducing food waste, supporting drought-resilient farming practices, and choosing eco-friendly grocery options all contribute to a more secure food future. Shopping smarter at the grocery store can reduce your grocery bills and your carbon footprint.
On the policy level, experts say we need stronger early warning systems, modernized water infrastructure, and equitable food distribution programs to help communities adapt to new climate realities. The report emphasizes that global cooperation is crucial — especially to protect the most vulnerable populations from being left behind.

Who Are Those Fantastic SuperAgers And Why Do They Stay Healthy?
Everyone wants to stay fully independent as we age. A few people over age 80 do and they don't suffer from memory loss either. They are called 'super agers' because they do not suffer the same mental and physical declines as almost everyone else. They've been studied by researchers for decades. We do have some answers to what makes them different from everyone else. Maybe we all wish we could be super agers ourselves. What Is A Super Ager? The term describes someone over 80 with an exceptional memory — one at least as good as the memories of people who are 20 to 30 years younger. They don't get Alzheimer's disease. They think clearly and participate in many things most folks their age cannot do. As reported in AARP, those who seem to defy normal changes of aging have a few things in common. Here are some of these, also reflected in research from other reports in other places in the U.S. 1. Thicker brains We don't know if it's a hereditary thing or not but with this rare group, the part of the brain which impacts thinking, memory and decision-making is thicker in super agers — sometimes thicker even than it is in most people in their 50s and 60s. It resists shrinking. 2. Supersize memory cells in their brains. These larger than average sized particular nerve cells resist the protein deposits associated with cognitive decline and Alzheimer's disease. The protein plaques and tangles may be present in the brains of those super agers, seen from those who donated their brains to studies after they pass, but they do not seem to cause damage. 3. More 'social intelligence' brain cells These particular kinds of brain cell cells have been linked to social intelligence and awareness. They help facilitate rapid communication across the brain, providing an enhanced ability to navigate the outside impacts thinking, memory and decision-making. As I see it, that would suggest greater levels of independence in aging, an elusive thing most want but few over 80 actually achieve. What If You Aren't Born With That Kind Of Brain? There is plenty of research on preventing dementia to tell us that lifestyle is perhaps the most important feature of aging well, whether you are destined to be a super ager or not. Most of the super agers are very active and maintain healthy habits. One of my favorite examples is the late Dr. Ruth Westheimer, the famous sex therapist. She was a TV personality, author of numerous books and, as she used to say, a nonstop talker. Her belief was that talking exercises the brain. OK, we know some nonstop talkers who are definitely not exercising their brains so that's not all there is to keeping one's brain active. But being silent and withdrawn is certainly not helpful lifestyle clearly includes regular exercise, even walking. It doesn't take running marathons. And food choices are part of this, of course as well. Data more recently shows a link between consuming ultra processed foods (sweets, packaged snacks, etc.) and cognitive decline. The better choices, as we are often told, include fish, vegetables, fruits and whole grains, avoiding junk food and excess. Other resources emphasize the importance of social connections in aging to help ward off dementia, getting enough sleep, and managing stress. Easier said than done! And one thing the super agers who have been studied also have in common is the unwavering willingness or ability to constantly challenge themselves. The Takeaway Not everyone will have a super ager's remarkably different kind of brain structure. But everyone can see their good health habits and aim for doing what they do. They stay active in many ways, socially engaged, and everyone can make that an achievable goal.

Is 'War of the Worlds' the worst movie of 2025?
It's got an epic title, a big-name star as its lead and a major studio behind it. But since it was released on Amazon's Prime Video on July 25, 'War of the Worlds" has become an all-time ratings bust. The new adaptation of H.G. Wells' book was ranked as one of the worst films of all time by the review aggregator site Rotten Tomatoes. The film stars Ice Cube as Homeland Security surveillance and threat assessment expert Will Radford, who uses government technology to spy on, and later help, his children amid an unfolding alien invasion. Radford is at his desk the entirety of the film, watching events unfold in front of him on a computer screen. Eva Longoria, Michael O'Neill, Olivia DeLaurentis and Clark Gregg also star in the movie, which was directed by Rich Lee. On Rotten Tomatoes, the sci-fi movie has a paltry 3% rating on the "Tomatometer," which tracks critic reviews, and 21% on the "Popcornmeter," which tracks audience reviews. Rotten Tomatoes' 'Worst Movies at All Time' list ranks 'War of the Worlds' 88th. The 2002 sci-fi thriller ' Ballistic: Ecks vs. Sever" is No. 1. The only other title from 2025 to make the list is Sylvester Stallone's 'Alarum.' Just one critic, Jordan Hoffman of Entertainment Weekly, gave "War of the Worlds" a certified fresh ranking, writing, " It's certainly stupid, but it's also a great deal of fun." Most others described the film as the worst take on Wells' 1898 novel about Martians invading Earth. Past adaptations include the Orson Welles-directed CBS Radio broadcast in 1938, a Gene Barry-starring 1953 Technicolor film and Steven Spielberg's 2005 film, which starred Tom Cruise. Lee 'butchers the classic sci-fi parable on humankind's colonialist ills and creates an obnoxiously dull, utterly braindead (arguable bootleg) exercise in capitalist, surveillance state propaganda,' wrote one Rotten Tomatoes critic. Some online noted that they felt like the movie's tagline — which is 'It's worse than you think' — is an appropriate way to summarize their reactions to the film itself. Lee and the cast have not publicly addressed the reaction. Neither Universal Pictures, which produced the film, nor Amazon Studios, which distributed it, responded to requests for comment. (Universal Pictures is a division of NBC News' parent company, NBC Universal.) But as with some other films that receive poor reviews, the reaction to "War of the Worlds" has also made it buzzy. Many viewers have transformed Ice Cube's reactions in various scenes into memes and GIFs. The film has solidified a place on the online database Know Your Meme. The website attributes the rise in online traction to a July 21 post on X from the user 'PoorOldRoloTony,' who shared a clip from the film. The user wrote, 'War of the Worlds (2025) is the worst adaption of the source material to date. It had no ideas beyond the found footage approach.' The post had been viewed 1.9 million times as of Tuesday. Users across TikTok and X have also continued to poke fun at the acting, dialogue, oversimplified device hacking and heavy-handed messaging about mass government surveillance and conspiracy theories. 'Sounds like Ice Cube is reading directly from a script that he had never seen before...,' a TikToker wrote in the text of their video, which featured a clip from the film. The video has been viewed 1.1 million times. One TikToker even impersonated Ice Cube, recording themselves dressed as him and reciting lines from the movie. Some viewers have also criticized the movie's placement of Amazon products, including scenes that feature a Prime Air delivery drone and a character receiving a $1,000 Amazon gift card. Vetz, a YouTube channel that ranks and review movies, cited the product placement as one of the main reasons the film ranks on its 10 worst movies of 2025 list. 'The worst product placement I've ever seen in my life,' said Joel, a reviewer for the channel, which has 261,000 subscribers. On the popular movie tracking platform Letterboxd, the film averaged just 1 star from the roughly 90,000 people who logged having watched it.

A plague mysteriously spread from Europe into Asia 4,000 years ago. Scientists now think they may know how
For thousands of years, a disease repeatedly struck ancient Eurasia, quickly spreading far and wide. The bite of infected fleas that lived on rats passed on the plague in its most infamous form — the Black Death of the 14th century — to humans, and remains its most common form of transmission today. During the Bronze Age, however, the plague bacterium, Yersinia pestis, had not yet developed the genetic tool kit that would allow later strains to be spread by fleas. Scientists have been baffled as to how the illness could have persisted at that time. Now, an international team of researchers has recovered the first ancient Yersinia pestis genome from a nonhuman host — a Bronze Age domesticated sheep that lived around 4,000 years ago in what is now modern-day Russia. The discovery has allowed the scientists to better understand the transmission and ecology of the disease in the ancient past, leading them to believe that livestock played a role in its spread throughout Eurasia. The findings were published Monday in the journal Cell. 'Yersinia pestis is a zoonotic disease (transmitted between humans and animals) that emerged during prehistory, but so far the way that we have studied it using ancient DNA has been completely from human remains, which left us with a lot of questions and few answers about how humans were getting infected,' said lead author Ian Light-Maka, a doctoral researcher at the Max Planck Institute for Infection Biology in Berlin. There have been nearly 200 Y. pestis genomes recovered from ancient humans, the researchers wrote. Finding the ancient bacterium in an animal not only helps researchers understand how the bacterial lineage evolved, but it could also have implications for understanding modern diseases, Light-Maka added via email. 'Evolution can sometimes be 'lazy,' finding the same type of solution independently for a similar problem — the genetic tools that worked for pestis to thrive for over 2000 years across over Eurasia might be reused again.' Unraveling the mystery of a Bronze Age plague The ancient bacterium that caused the Eurasia plague, known today as the Late Neolithic Bronze Age lineage, spread from Europe all the way to Mongolia, with evidence of the disease found across 6,000 kilometers (3,700 miles). Recent evidence suggests that the majority of modern human diseases emerged within the last 10,000 years and coincided with the domestication of animals such as livestock and pets, according to a release from the German research institute. Scientists suspected that animals other than rodents were a part of the enormous puzzle of the Bronze Age plague transmission, but without any bacterial genomes recovered from animal hosts, it was not clear which ones. To find the ancient plague genome, the study authors investigated Bronze Age animal remains from an archaeological site in Russia known as Arkaim. The settlement was once associated with a culture called Sintashta-Petrovka, known for its innovations in livestock. There, the researchers discovered the missing connection — the tooth of a 4,000-year-old sheep that was infected with the same plague bacteria found in humans from that area. Finding infected livestock suggests that the domesticated sheep served as a bridge between the humans and infected wild animals, said Dr. Taylor Hermes, a study coauthor and an assistant professor of anthropology at the University of Arkansas. 'We're sort of unveiling this in real time and trying to get a sense for how Bronze Age nomadic herders out in the Eurasian Steppe were setting the stage for disease transmission that potentially led to impacts elsewhere,' Hermes said, 'not only in later in time, but also in a much more distant, distant landscape.' During this time within the Eurasian Steppe, as many as 20% of the bodies in some cemeteries are those of people who were infected with, and most likely died from, the plague, making it an extremely pervasive disease, Hermes said. While livestock are seemingly a part of what made the disease so widespread, they are only one piece of the puzzle. The identification of the bacterial lineage in an animal opens new avenues for researching this disease's evolution as well as the later lineage that caused the Black Death in Europe and the plague that's still around today, he added. 'It's not surprising, but it is VERY cool to see (the DNA) isolated from an ancient animal. It's extremely difficult to find it in humans and even more so in animal remains, so this is really interesting and significant,' Hendrik Poinar, evolutionary geneticist and director of the Ancient DNA Centre at McMaster University in Hamilton, Ontario, wrote in an email. Poinar was not involved with the study. It is likely that humans and animals were passing the strains back and forth, but it isn't clear how they did so — or how sheep were infected in the first place. It is possible sheep picked up the bacteria through a food or water source and then transmitted the disease to humans via the animal's contaminated meat, he added. 'I think it shows how extremely successful (if you want to label it that way) this particular pathogen has been,' Poinar added. He, as well as the study's authors, said they hope that further research uncovers other animals infected with the ancient strain to further the understanding of the disease's spread and evolution. Ancient plague to modern plague While the plague lineage that persisted during the Bronze Age is extinct, Yersinia pestis is still around in parts of Africa and Asia as well as the western United States, Brazil and Peru. But it's rare to encounter the bacteria, with only 1,000 to 2,000 cases of plague annually worldwide. There is no need for alarm when it comes to dealing with livestock and pets, Hermes said. The findings are a reminder that animals carry diseases that are transmittable to humans. Be cautious when cooking meat, or to take care when bitten by an animal, he added. 'The takeaway is that humans aren't alone in disease, and this has been true for thousands of years. The ways we are drastically changing our environment and how wild and domesticated animals are connected to us have the potential to change how disease can come into our communities,' Light-Maka said. 'And if you see a dead prairie dog, maybe don't go and touch it.' Taylor Nicioli is a freelance journalist based in New York. Sign up for CNN's Wonder Theory science newsletter.
