Scientists thrilled as ultra-rare flower once thought to be extinct begins to flourish in wild: 'We don't yet know its potential'
Researchers in China are celebrating the reemergence of a flower that was once thought to be extinct for over a century, according to GD Today.
Primulina tabacum is a "calciphilous perennial herb found only at the entrances of a small number of karst cave drainages in southern China," according to the U.S. Department of Agriculture. It was discovered in the 1880s but was not seen again until three plants were spotted in the 1990s.
Since then, researchers at the Chinese Academy of Sciences have worked in partnership with the Dinghushan National Nature Reserve and South China Botanical Garden to ensure the plant's survival.
Primulina tabacum has enjoyed a healthy expansion throughout karst caves in Guangdong, China. The SCBG has a handful of locations for its conservation efforts, including its "display zone," which is home to over 18,000 taxa growing in 38 theme gardens. Inside the SCBG's Dinghushan National Nature Reserve, over 2,400 plant species are spread across 1,155 hectares (around 2,854 acres).
In 2002, the SCBG team established an ex situ conservation program in the hope of protecting rare and threatened plant species, as detailed by GD Today. Ex situ refers to something being located outside its natural place or habitat. These sites can serve as a safeguard against extinction and a means to study and understand plant diversity.
Ning Zulin, deputy director of SCBG's horticulture center, noted the central objective for plant conservationists, per GD Today: "We protect each plant not because of its known value, but because we don't yet know its potential. Once a species vanishes, it's irreversible."
Plant conservation programs can play a crucial role in maintaining healthy ecosystems, providing essential resources for humans and wildlife, and ensuring the overall health of the planet. Plants provide food, oxygen, and clean water for countless species. They have a major impact on biodiversity in many regions throughout the world.
Wang Ding of the Chinese National Committee for Man and the Biosphere Programme emphasized the importance of conservation efforts. "Nature reserves should bridge socio-economic development, not hinder it," he said, per GD Today. "Harmony with nature is our guiding principle."

Missouri conservation staff tracking peregrine falcons in Kansas City
KANSAS CITY, Mo. — The Missouri Department of Conservation has been working this month to track a certain bird of prey that has been reintroduced to urban areas in past decades. Peregrine falcons could become a more common sight in the Kansas City area and elsewhere statewide as the conservation department's peregrine falcon nesting program takes flight. Overland Park residents can apply for property tax rebate starting this weekend Kansas City was included in the nesting program in 2019, and this month, the department has been providing updates as it works to grow the population of peregrine falcons in the state, a species labeled a 'conservation concern.' Earlier this month, conservation department staff and a representative from the U.S. Department of Agriculture met up on the rooftop of the Shook, Hardy and Bacon law firm building in Kansas City to place leg bands on three peregrine falcon chicks living in a nesting box. The department shared on Facebook recently that they offer the nesting boxes as a safer alternative for falcons that have historically built their nests on cliffs and ledges. Leg bands have been placed on several young falcons this month, the department said, in an effort to keep track of where the birds go once they leave the nest. The leg bands are large enough to fit the birds as they grow into adults and included identification numbers, the department said. This week, the department included an update that staff members added leg bands to three more chicks, this time at Evergy's Hawthorn station in Kansas City. 'MDC staff recently banded peregrine falcon chicks at EVERGY's Hawthorn Generating Station in Kansas City,' the department posted on Facebook Wednesday. 'There were 2 males and 1 female, all in excellent health. EVERGY staff hold their newest family members with great pride.' FOX4 Newsletters: Sign up for daily forecasts and Joe's Weather Blog in your inbox Here are some facts about peregrine falcons, provided by the Missouri Department of Conservation and the Cornell Lab: One of the world's fastest birds, peregrine falcons can reach speeds of 200 mph as they dive toward their prey from a high-up location. The species was nearly eradicated because of side-effects of DDT and other pesticides in the middle of the 20th century. They hunt starlings, pigeons and other smaller birds seen in the city.

What's The Ideal Time Of Day To Eat Protein? Probably Not When You Think—Here's What Experts Say
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Protein is a hot topic of conversation, especially when it comes to women as some experts say that they likely need to eat more protein than what they're currently consuming. When it comes to protein timing, the hour of the day during which you consume protein doesn't matter, in and of itself, quite as much as how you distribute your intake throughout the day. If you're like most Americans, you're probably getting the bulk of your protein at dinner. Women between the ages of 20 and 49 were found, on average, to consume about 42 percent of their daily protein at dinner and just 17 percent at breakfast, per a survey conducted by the U.S. Department of Agriculture's (USDA) Agriculture Research Service. What we should be aiming for instead is an equal distribution of protein throughout the day, say experts.$9.99 at 'Research shows spreading out protein intake every three to four hours or so into moderate doses versus a lot at once is associated with more optimal muscle repair and for those who are looking for growth, more optimal growth too,' says Jones. Indeed, evenly spreading protein consumption among meals, rather than skewing it towards dinner 'stimulated 24-hour muscle protein synthesis more effectively,' according to researchers at the University of Texas Medical Branch. The body benefits could be due to the way our body metabolizes protein and its building block, amino acids. Whereas surplus carbohydrates are stored in the body as glycogen and surplus fat as body fat, amino acids aren't squirreled away as amino acids to be used later. Rather, after our body has used what it can of the protein we eat at a meal—by supporting metabolism, producing hormones, maintaining bones and, yes, aiding muscle protein synthesis—it is then converted into either fat or glucose. Research seems to indicate that around 20-25 grams of protein at one time is the upper limit that our body can use in muscle synthesis (though one study put the number closer to 30 grams). Essentially, anything in excess of 20-30 grams at a single meal may not make a huge difference as far as protein actions in the body go. Another reason you may want to consider equal distribution throughout the day? You'll probably just get less hangry. 'People notice that when they start to emphasize protein at breakfast and they ensure that it's there at their snack too, they feel more satiated throughout the day,' Jones says. 'They're less likely to be distracted by hunger, they're less likely to have blood sugar spikes and crashes.' So do I need to eat protein right after a workout? Perhaps you've heard the term anabolic or metabolic window (they're often used interchangeably), which refers to the time period after a workout in which your muscles are repairing themselves and nutrition can play a role in aiding that process. Depending on who you talk to, you may be told that time period is as brief as 15 minutes. Which would essentially mean you'd have to sip a protein shake while showering in order to get the timing just right. Thankfully, research has led experts to widen this window considerably, to three or four hours (sometimes even five or six if you're really pushing it). But the experts WH spoke with agreed that within two hours is optimal. 'Don't go longer than two hours, and if you have big goals for gaining muscle and repairing muscle, get it closer to your workout, if you can,' says Jones. As for the amount of protein, aim for 20-25 grams post-workout, recommends Tracy Anthony, PhD, a professor of nutritional sciences at Rutgers University in New Brunswick, New Jersey. What about -sweat protein? Should I be eating that? If all of this talk about post-workout fueling has you wondering about pre-workout fueling, we have that answer too. If you're exercising for an hour or less, you probably don't need to worry about protein intake ahead of time and can simply focus on getting high-quality protein after, says Jones. Want more protein inspiration? Join WH+ to get the high-protein meal prep manual for breakfast, lunch, dinner, and snack recipes. However, if you're going for, say, a two-hour run or you tend to feel peckish if you don't eat before exercising, grab a carb-rich snack with a few grams of protein first. 'It will help a little bit with your energy levels and reducing the amount of muscle damage you're going to have go on there too,' Jones says.

A Flesh-Eating Parasite Is Advancing Toward the U.S.
The United States has, for 70 years, been fighting a continuous aerial war against the New World screwworm, a parasite that eats animals alive: cow, pig, deer, dog, even human. (Its scientific name, C. hominivorax, translates to 'man-eater.') Larvae of the parasitic fly chew through flesh, transforming small nicks into big, gruesome wounds. But in the 1950s, the U.S. Department of Agriculture laid the groundwork for a continent-wide assault. Workers raised screwworms in factories, blasted them with radiation until they were sterile, and dropped the sterile adult screwworms by the millions—even hundreds of millions—weekly over the U.S., then farther south in Mexico, and eventually in the rest of North America. The sterile flies proceeded to, well, screw the continent's wild populations into oblivion, and in 2006, an invisible barrier was established at the Darién Gap, the jungle that straddles the Panama-Colombia border, to cordon the screwworm-free north off from the south. The barrier, as I observed when I reported from Panama several years ago, consisted of planes releasing millions of sterile screwworms to rain down over the Darién Gap every week. This never-ending battle kept the threat of screwworms far from America. But in 2022, the barrier was breached. Cases in Panama—mostly in cattle—skyrocketed from dozens a year to 1,000, despite ongoing drops of sterile flies. The parasite then began moving northward, at first slowly and then rapidly by 2024, which is when I began getting alarmed emails from those following the situation in Central America. As of this month, the parasite has advanced 1,600 miles through eight countries to reach Oaxaca and Veracruz in Mexico, with 700 miles left to go until the Texas border. The U.S. subsequently suspended live-cattle imports from Mexico. After this latest news broke, I spoke with Wayne Cockrell, a Texas rancher who fears the screwworm's return to Texas is now a matter of when, not if. The anti-screwworm program cannot produce enough sterile flies to stop the parasite's advance, much less beat it back down to Panama, Cockrell explained. He has followed the outbreak closely as the chair of the cattle-health committee for the Texas and Southwestern Cattle Raisers Association, even visiting the sterile-fly factory recently. 'There's a sense of dread on my part now,' he told me. At 60, he is too young to remember screwworms himself, but he's heard the horror stories. Every cut, every scratch, every navel of a newborn calf threatened to turn fatal in the pre-eradication era. If the parasite does take hold in the U.S. again, it could take decades to push screwworms back down to Panama. That is, after all, how long it took the first time. Decades of screwworm vigilance have been undone in just two years. You only have to glance at a map to understand why the screwworm outbreak is now at an alarming inflection point. Central America is shaped like a funnel with a long, bumpy tail that reaches its skinniest point in Panama. Back in the day, the USDA helped pay for screwworm eradication down to Panama out of not pure altruism but economic pragmatism: Establishing a 100-mile screwworm barrier there is cheaper than creating one at the 2,000-mile U.S.-Mexico border. Even after screwworms began creeping up the tail of the funnel recently, the anti-screwworm campaign had one last good chance of stopping them at a narrow isthmus in southern Mexico—after which the funnel grows dramatically wider. It failed. The latest screwworm detections in Oaxaca and Veracruz are just beyond the isthmus. The wider the new front of the screwworm war grows, the more sterile screwworms are needed to stop the parasite's advance. But the supply is already overstretched. The fly factory in Panama has increased production from its usual 20 million flies a week to its maximum of 100 million, which are now all being dispersed over Mexico. But planes used to drop 150 million flies a week over the isthmus in Mexico during the first eradication campaign in the 1980s. And when the front was even farther north in Mexico, a factory there churned out as many as 550 million flies weekly to cover the huge area. That factory, as well as one in Texas, has long since shut down. The Texas and Southwestern Cattle Raisers Association is asking the USDA to build a new sterile-fly plant in the U.S., one big enough to produce the hundreds of millions that may soon be necessary. 'We are working closely with Mexico to reestablish a biological barrier and prevent further geographic spread,' a USDA spokesperson wrote in response to questions about the adequacy of sterile-fly production. 'If the fly spreads further geographically, we will need to reevaluate production capacity.' Several Texas lawmakers recently introduced the STOP Screwworms Act, which directs the USDA to open a new factory, but the whole process could still take years. 'The facility needs to start tomorrow,' Cockrell said. The U.S. cattle industry is unprepared for the screwworm's return, he said, rattling off more reasons: Certain drugs to treat screwworm infection are not licensed in the U.S., having been unnecessary for half a century. Ranches used to employ 50 cowboys who regularly inspected cattle, and now they might have only five. And routine industry practices such as branding and ear tagging leave the animals vulnerable to screwworm infection. To face the screwworm, the cattle industry will have to adapt quickly to a new normal. The parasite could propel beef prices, which are already sky-high due to drought, even higher. How screwworms managed to jump the barrier in 2022 is not fully clear. But in the years immediately before, the coronavirus pandemic reportedly created supply-chain snarls at the fly factory in Panama and disrupted regular cattle inspections that might have set off the alarm bells earlier. And the border between Panama and Colombia got a lot busier; the Darién Gap, once a notoriously impenetrable jungle, became a popular route for migrants. Still, the screwworm advanced relatively slowly through Panama and Costa Rica for the first couple of years. Then it hit Nicaragua, and over just 10 weeks in 2024, it shot from the country's northern border through Honduras and Guatemala to reach Mexico. This rapid advance was because of the illegal cattle trade, Jeremy Radachowsky, the director for Mesoamerican and the Western Caribbean at the Wildlife Conservation Society, told me. His organization has tracked the practice in Central America, where 800,000 cattle a year are raised illegally in nature reserves and then smuggled by boat and truck up to Mexico. This allowed the screwworm to spread much faster than it can fly. The line of new screwworm cases followed known smuggling routes, Radachowsky said. The constant northward movement of infected cattle could now make re-eradication more difficult. It's like trying to empty a pool when 'the spigot's still open,' he said. Decades of screwworm-free existence meant that even ranchers, whose livelihoods are directly affected, were slow to recognize the growing emergency. 'We were so successful that literally people forgot,' a U.S. official in Central America familiar with the situation (speaking anonymously due to the delicate politics involved) told me. Inspections, timely reports of infection, and restrictions on cattle movement are important pieces of eradication, in addition to the release of sterile flies. Over the years, scientists have also proposed more advanced ways of controlling the screwworm through genetics, though none is yet ready for prime time. The USDA supported research by Max Scott, an entomologist at North Carolina State University, to create a male-only strain that could reduce the number of flies needed for dispersal, but funding ended last summer. He has also proposed using gene drives, a still-controversial technique that could rapidly 'drive' genetic material that makes females sterile into the wild population. The USDA wasn't interested, he told me. (A spokesperson says the USDA 'continues to research and investigate new tools,' including genetically engineered male-only screwworms.) But he did strike up a collaboration several years ago with scientists in Uruguay studying a gene drive for sterile screwworms. Uruguay is interested because it never got to benefit from screwworm eradication; the country is located about halfway down South America, deep in screwworm territory. A retired USDA scientist, Steven Skoda, told me that he and his colleagues used to dream of 'a world totally free of screwworm.' But eradication never reached South America, and now even the barrier protecting North America is no longer intact. The campaign to push screwworms from the south of Mexico—roughly where the parasite is right now—to the southern edge of Panama took 21 years. The way things are going, Cockrell said, some of his longtime colleagues in Panama might not see screwworms eradicated again in their country in their lifetime.
