  • A shock to the food system

    WASHINGTON, D.C. — Feeding the world’s population is a big challenge, and it’s about to get bigger. Right now, a little more than 7.3 billion people share the planet. Most nights, many go to bed hungry. By 2050, some scientists estimate, the world’s population may reach 9 billion. Earth’s changing climate will probably make feeding this far greater number a very daunting task. That was the...

  • Building better, safer soils

    BALTIMORE, Md. — Urban farming can help families in inner cities enjoy more fresh fruits and vegetables. Community gardens also help people get exercise and bring neighbors together. But there’s one big problem. Soils in many cities have high levels of lead. That toxic heavy metal harms the brain and nervous system, leading to health problems, especially in children. But scientists have just...

  • New gene resists our last-ditch drug

    Antibiotics are drugs that can kill bacteria. But many germs have evolved genes that make them immune to one or more of these drugs. In some cases, only one lone drug remains that can kill them. If bacteria found a way to resist — ignore — that last drug too, these killer germs might be unstoppable. Infections that were once easy to treat would become incurable. And, new data show, bacteria...

  • Banana threat: Attack of the clones

    The fight to save the banana just got more challenging. A fungus that threatens the world’s most popular fruit is spreading, according to a new study. And it’s doing so despite massive efforts to stop it.

    At risk is the sweet “Cavendish” banana sold in North America and Europe. But that's not all. There are 400 edible varieties of banana, and many of them also are susceptible to killing...

  • Profile: A human touch for animals

    Temple Grandin, 68, is one of the world’s top experts on nurturing farm animals. She trains farmers and ranchers to raise livestock without causing them pain or fear. Those methods and insights make their care — called animal husbandry — faster and easier because the animals do not become anxious.

    Grandin also has designed slaughterhouses, facilities where animals are killed for food....

  • Cool Jobs: Crazy about cows

    Without cows, our diets would look very different. We’d go without hamburgers, grilled cheese sandwiches and barbecue beef. We wouldn’t melt butter on pancakes or put milk in our cereal.

    There would be no ice cream.

    Until the 1850s, most American families had their own cows. Now, most people live some distance from their nation’s 9.3 million dairy cows and 90 million beef cattle....

  • The dirt on soil

    Soil is easy to ignore. We might notice it when gardening or playing outdoors. But even when we forget about it, soil is always there, everywhere.

    Most of what we see are mineral particles that we recognize as sand, silt or clay. There's also plenty of water and air. But soil also is alive. It contains countless fungi and microbes. They help recycle the dead by breaking down the remains...

  • Weed killers may go from plant to pooch

    Many people treat their lawns with weed killers — also known as herbicides — to rid themselves of unwanted plants, such as dandelions. Most people know to keep small children away from the grass after it’s been sprayed. That’s because these chemicals can be dangerous if children touched the treated lawn and then put their hands to their mouths. New data show that herbicides also can end up in...

  • ‘Wildlife-free’ farms don’t make salads safer

    Eating veggies is good for your health — as long as they are free of disease-causing germs. Some of those germs can come from birds, rabbits and other animals that wander in and near fields where crops are growing. Keeping animals out should therefore prevent major outbreaks of illness. Or that’s been the idea behind moves to limit wildlife’s access to crops. But a new study finds that fencing...

  • Made in the shade

    There's a bonus to growing coffee in a traditional way that preserves tall trees — and it's not just for the birds.

    Scientists recently found a rich and diverse bird population living in the shade of forested coffee farms. Those farms are in the east African nation of Ethiopia. Ample birdlife is just one of many benefits of this type of farming, called agroforestry. The practice mixes in...
