MacArthur Park is in the middle of Los Angeles, near downtown. At the center of the park is a small lake, and it's not most people's idea of a picturesque fishing spot.

It was there that the California Ghetto Carping club caught a record breaking fish this week — a 50-pound carp.

Update 7:06 P.M. Eastern: The EPA says it's reversing course and keeping chlorpyrifos on the market.

That's despite the agency's earlier conclusion, reached during the Obama administration, that this pesticide could pose risks to consumers. It's a signal that toxic chemicals will face less restrictive regulation by the Trump administration.

You'd think that a vaccine that protects people against more than a half dozen types of cancer would have patients lining up to get it. But the human papillomavirus (HPV) vaccine, which can prevent roughly 90 percent of all cervical cancers as well as other cancers and sexually transmitted infections caused by the virus, has faced an uphill climb since its introduction more than a decade ago.

So last year, Ian Griffin, an astronomer in Dunedin, New Zealand, was able to catch a ride on the NASA SOFIA. It's a Boeing 747 airplane with an observatory on board.

IAN GRIFFIN: And on that flight it had an absolutely amazing view of the aurora australis.

President Trump issued a sweeping executive order on Tuesday that will begin to undo a slew of government efforts to fight global warming.

Among those worrying and watching to see how the executive order plays out are scientists who actually are in favor of exploring bold interventions to artificially cool the climate.

A New Kind Of March Madness Hits Schools

Mar 29, 2017

It's a little after 8 a.m. at Wakefield High School in Arlington, Va., and Michelle Harris' AP Environmental Science class is getting right to it.

"All right, you guys got your brackets out?" Harris asks.

The class of mostly juniors and seniors ruffle through folders and pull out pieces of paper with brackets — 64 slots, four quadrants, and one central box to predict the championship. But there's something a little different about these brackets ...

"We're going to jump down to the fourth-seeded spider monkey against the 12th-seeded antelope squirrel," Harris says.

A paralyzed man has regained the use of his arm and hand using a system that decodes his thoughts and controls his muscles.

Breast-feeding has many known health benefits, but there's still debate about how it may influence kids' behavior and intelligence.

Now, a new study published in Pediatrics finds that children who are breast-fed for at least six months as babies have less hyperactive behavior by age 3 compared with kids who weren't breast-fed.

But the study also finds that breast-feeding doesn't necessarily lead to a cognitive boost.

For a girl growing up on a one-lane dirt road in a Connecticut town, it seemed the only way to look was up.

But Nancy Miorelli was nearsighted, so although she spent most days outside until dinnertime, she couldn't see the birds flying above her head.

"So I guess that left things that were crawling on the ground," the 27-year-old entomologist says.

Yep, bugs. But poor eyesight isn't the reason she puts herself in what others might feel is nightmarish proximity to bugs these days.

Telehealth takes a lot of forms these days. Virtual visits with a health care provider can take place by video, phone or text, or via the Web or a mobile app. The one commonality: You get to consult a doctor from your home, the office, Starbucks or anywhere with a wifi or mobile connection.

These appointments can be quick, and save you from having to schlep across town and sit in a waiting room, leafing through year-old Time magazine articles, as prelude to every visit with a doc.

Doctors say it all started eight years ago, when a urology clinic in Oregon ran an ad promoting the benefits of scheduling a vasectomy in March.

"You go in for a little snip, snip and come out with doctor's orders to sit back and watch nonstop basketball," the voice-over promises. "If you miss out on this, you'll end up recovering during a weekend marathon of Desperate Housewives!"

When the Food and Drug Administration created controls in January on how farmers can give antibiotics to livestock, scientists concerned about antibiotic resistance and advocates for animal welfare called it a historic shift in how meat animals are raised.

But a new federal report, released last week, says the long-awaited FDA initiative — first attempted back in 1977 — falls short in so many areas that it may not create the change that backers hoped for.

Growing up in a hungry household in the first couple of years of life can hurt how well a child performs in school years later, according to a new study.

An estimated 13.1 million children live in homes with insufficient food, according to the most recent figures from the U.S. Department of Agriculture.

Cancer can be caused by tobacco smoke or by an inherited trait, but new research finds that most of the mutations that lead to cancer crop up naturally.

The authors of the study published Thursday poked a hornet's nest by suggesting that many cancers are unavoidable.

It was a meeting of nerds and sharks.

The self-described "biotech nerds" and "robotic nerds" were seven high school students from Washington, D.C. The eight teens who call themselves "sharks" and flew in from Ghana. "The shark is a big fish so it means you're big. Knowledgeable," explains Stephanie Obbo of Ghana, an aspiring medical doctor.

In 2015, when researchers Anne Case and Angus Deaton discovered that death rates had been rising dramatically since 1999 among middle-aged white Americans, they weren't sure why people were dying younger, reversing decades of longer life expectancy.

Now the husband-and-wife economists say they have a better understanding of what's causing these "deaths of despair" by suicide, drugs and alcohol.

It's hard not to get excited about news of a potentially effective treatment for sepsis, a condition that leads to multiple organ failure and kills more people in the hospital than any other disease.

But there have been so many false promises about this condition over the years, it's also wise to treat announcements — like one published online by the journal, Chest — with caution.
