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.

Uber is in crisis. This week the president resigned, after just six months on the job. Morale has been shaken following a damning account of sexual harassment. The board of directors is so concerned about the CEO's ability to lead, they're looking for a No. 2 to help steer the company.

The U.S. Senate has a lot going on: confirmation hearings for a Supreme Court nominee, negotiations on repealing the Affordable Care Act, votes on gun sales regulations and bear-hunting rules for Alaska.

Here's a classic big city dilemma (sorry suburban folks): It's late at night, the weather is bad, and you're hungry. Your favorite restaurant is less than a mile away, but you don't want to leave the house, and you don't want to pay a $5 delivery fee — plus tip — for a $10 meal.

So, what do you do?

Back in the old days, you would have braved the elements — or learned to plan ahead. But those days are coming to an end, at least in Washington, D.C.

For the first time in birds, researchers say they have found evidence that a New Zealand parrot has the avian equivalent of an infectious laugh.

They call it "positive emotional contagion" — which they define as "outwardly emotional actions that spread from one individual to another." In humans, this is what happens when one person hears another laugh and also starts cracking up.

Men may soon be able to take their own sperm count — at home. With a smartphone. Yes, there's an app for that.

You may be asking yourself, why?

Low sperm count is a marker for male infertility, a condition that is actually a neglected health issue worldwide, according to the World Health Organization.

By a largely party-line vote Tuesday, the Senate approved a bill that repeals Obama-era hunting restrictions on national wildlife refuges in Alaska. The House already voted last month to abolish those restrictions — which were instituted by the Fish and Wildlife Service in 2016 to protect predator species from hunters — and so the bill now heads to the desk of President Trump, who is widely expected to sign it.

Though he didn't come from a farming family, from a young age Tim Joseph was fascinated by the idea of living off the land. Reading magazines like The Stockman Grass Farmer and Graze, he "got hooked on the idea of grass-fed agriculture — that all energy and wealth comes from the sun," he explains, "and the shorter the distance between the sun and the end product," the higher the profit to the farmer.
