New study shows that the restoration of this ocean feature could protect thousands of lives: 'We level the playing field'
Restoring coral reefs can save thousands of lives, hundreds of millions of dollars, and our most at-risk neighbors, according to Phys.org.
A new study shows that bringing coral reefs back to health along the Florida and Puerto Rico coasts could shield nearly 3,000 people from storm damage each year. The restored reefs would block $391 million in property damage and business losses annually.
The study, published Jan. 15 in Science Advances, comes from researchers at UC Santa Cruz and the U.S. Geological Survey. They checked how much flooding occurs with and without healthy reefs, measuring impacts in areas as small as 108 square feet.
The research showed coral reefs defend coastlines by absorbing strong waves before they hit the shore. This natural shield works better than concrete seawalls since reefs can grow taller as sea levels rise. Healthy reefs support fishing, tourism, and recreation, making their actual value even higher than the numbers show.
The benefits flow directly to those who need them most. People living further inland from beachfront properties (often children, seniors, minorities, and lower-income residents) would gain two to three times more protection than the general population.
"Our modeling is a major advance in characterizing the effectiveness of nature-based infrastructure for coastal protection. The approach can also be applied to other ecosystems, such as beaches, marshes, oyster reefs, and mangrove forests," said Borja Reguero, who led the research at UC Santa Cruz.
"This modeling system can be used to assess the impacts of future changes in storms or sea level, helping us to measure when and how cost effective it is to adapt."
The study opens new doors for funding reef restoration through disaster prevention programs.
"Most hazard mitigation and disaster-recovery funding supports more artificial infrastructure such as seawalls that degrade nature. By valuing the benefits of natural infrastructure, we level the playing field and open major new funding opportunities for reef restoration," said Michael W. Beck, director of UC Santa Cruz's Center for Coastal Climate Resilience.
Smart investments in nature keep paying off. Earlier research found that existing reefs protect over 18,000 Americans and prevent $1.8 billion in flood damage yearly.

Eat your beans — 1 cup a day cuts inflammation and bad cholesterol, scientists say
Beans of all kinds are nutritional powerhouses of fiber, protein, and antioxidant polyphenols. A new study found specific types of beans like chickpeas helped participants lower cholesterol levels. Eating a cup of beans per day could help lower inflammation, and they're cheap and easy to cook with. A daily dose of beans can cut cholesterol, lower inflammation, and may help fend off chronic illnesses like heart disease, new research suggests. A group of researchers from the Illinois Institute of Technology looked at 72 adults with prediabetes for three months, long enough to see changes in health metrics like blood sugar control. The participants were divided into three groups. One group was instructed to add a cup of black beans per day to their normal routine. Another group added a daily cup of chick peas. The third, the control group, ate white rice instead of beans. By the end of the 12-week study, participants who ate chickpeas reduced their cholesterol levels around 10%, from high — an average of 200.4 milligrams per deciliter (mg/dL) — to normal — 185.8 mg/dL. Participants who ate black beans saw a significant drop in their inflammation levels. The study, presented at the American Society for Nutrition's annual conference June 3, focused on people with prediabetes — a condition that affects more than a third of Americans. Many don't get diagnosed until it becomes advanced and is harder to manage. Diet strategies like adding beans could be a way to intervene before people develop diabetes or other health issues, Indika Edirisinghe, principal investigator in the study and professor Illinois Institute of Technology, told Business Insider. "The small change is helpful. Just 10% is like saving your life, saving your money. This is not rocket science." Beans are rich in fiber, a type of carbohydrate that helps support healthy digestion and metabolism. It also feeds beneficial bacteria in our gut known as the microbiome, which are linked to everything from good mental health to healthy aging. Beans also offer a range of polyphenols, plant-based compounds that help reduce inflammation and oxidative stress which contribute to disease. While a wealth of previous research has linked eating beans to longevity and heart health, many past studies weren't rigorous enough to show beans cause the benefits. This study used direct measurements of change like blood tests. They also uniquely assessed the health effects of different types of beans separately, instead of looking at legumes more generally. Having one group eat chickpeas and another eat black beans allowed researchers to look for potential benefits of different nutrients, Morganne Smith, a doctoral candidate at Illinois Institute of Technology who presented the study at the conference, told Business Insider. Don't be intimidated about adding beans to your daily diet. There are lots of ways to get creative without much time, prep work, or expensive ingredients. Smith said she's already a bean enthusiast, but her family has been enjoying them even more often recently with simple bean recipes. "I try to look for easy ways. Nothing too fancy," she said. To get started: Mix up a bean salad with chopped onions, tomatoes, cucumbers, and any leftover veggies you have on hand. Blend beans into a soup to create a thicker texture and add nutrients. Snack on hummus or other bean-based dips. Opt for chickpea pasta instead of wheat-based paste for more protein and fiber. Try beans for breakfast! Edirisinghe starts the day with chickpeas sauteed in coconut, olive oil, lemon juice, and a dash of salt and pepper. You can also experiment with different seasonings to create more variety in your bean regimen. Turmeric, for instance, can add earthiness and bright color, as well as a boost of anti-inflammatory benefits. Beans are also a healthy eating staple because they're both affordable and easy to find, said Smith. "On top of the health benefits, I'm excited about the idea that people will think 'That's really easy to just continue incorporating in my diet realistically,'" she said.

Researchers create game-changing tool to address hidden farmland threat: 'We wanted the tool to be as versatile as possible'
A new open-source software is making it easier than ever to monitor heat-trapping gases emitted by livestock, according to an Elsevier report published on While much of the heat-trapping gas in the world is produced by burning fuel, another significant chunk of it comes from animal agriculture. As part of their digestive processes, animals like cows burp out methane, a potent planet-warming gas. Exactly how much methane is produced and what factors change that amount is obviously difficult to track. Animals are often outdoors or in partially enclosed spaces, and their gases easily escape. But a device called GreenFeed helps track these emissions in real time. It uses feed pellet rewards to encourage livestock to put their heads inside the device, then tracks the gases they produce. Then, users have the opposite problem: There is a lot of data about every burp produced by every individual animal. "The sheer volume of data produced by GreenFeed systems can be really overwhelming," said Guillermo Martinez-Boggio, the lead author of the new article, per Elsevier. "We set out to create an open-source tool that simplifies this process, making it more efficient and reproducible, and flexible to the variety of situations in which these systems are used." That tool is greenfeedr, based on the idea of "doing as little as possible by hand and as much as possible with functions." It helps download and sort through data from GreenFeed systems, compiling summaries about various types of data like an animal's total daily visits, how many pellets it's eaten, and the gas produced. "We wanted the tool to be as versatile as possible, so it was designed to be used with all livestock species and housing systems, including freestall, tiestall, and pasture-based," said Martinez-Boggio. The result makes it easier to understand how animals are producing heat-trapping gases, and that will make it easier to deploy solutions like this feed additive that cuts back on the methane in cow burps. One day, we may be able to bring down the Earth's overheating using this data. Do you think EVs are good for off-roading? They're better than gas cars They're as good as gas cars They're worse than gas cars I'm not sure Click your choice to see results and speak your mind.
