Alabama authorities say a home burglary suspect has died after police used a stun gun on the man.  Birmingham police say he resisted officers who found him in a house wrapped in what looked like material from the air conditioner duct work.  The Lewisburg Road homeowner called police Tuesday about glass breaking and someone yelling and growling in his basement.  Police reportedly entered the dwelling and used a stun gun several times on a white suspect before handcuffing him.  Investigators say the man was "extremely irritated" throughout and didn't obey verbal commands.

Montgomery Education Foundation's Brain Forest Summer Learning Academy was spotlighted Wednesday at Carver High School.  The academic-enrichment program is for rising 4th, 5th, and 6th graders in the Montgomery Public School system.  Community Program Director Dillion Nettles, says the program aims to prevent learning loss during summer months.  To find out how your child can participate in next summer's program visit Montgomery-ed.org

A police officer is free on bond after being arrested following a rash of road-sign thefts in southeast Alabama.  Brantley Police Chief Titus Averett says officer Jeremy Ray Walker of Glenwood is on paid leave following his arrest in Pike County.  The 30-year-old Walker is charged with receiving stolen property.  Lt. Troy Johnson of the Pike County Sheriff's Office says an investigation began after someone reported that Walker was selling road signs from Crenshaw County.  Investigators contacted the county engineer and learned signs had been reported stolen from several roads.

Convention Countdown

The Republican National Convention is in 4 days in Cleveland.

The Democratic National Convention is in 11 days in Philadelphia.

NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.

My husband and I once took great pleasure in preparing meals from scratch. We made pizza dough and sauce. We baked bread. We churned ice cream.

Then we became parents.

Now there are some weeks when pre-chopped vegetables and a rotisserie chicken are the only things between us and five nights of Chipotle.

Parents are busy. For some of us, figuring out how to get dinner on the table is a daily struggle. So I reached out to food experts, parents and nutritionists for help. Here is some of their (and my) best advice for making weeknight meals happen.

"O Canada," the national anthem of our neighbors up north, comes in two official versions — English and French. They share a melody, but differ in meaning.

Let the record show: neither version of those lyrics contains the phrase "all lives matter."

But at the 2016 All-Star Game, the song got an unexpected edit.

At Petco Park in San Diego, one member of the Canadian singing group The Tenors — by himself, according to the other members of the group — revised the anthem.

School's out, and a lot of parents are getting through the long summer days with extra helpings of digital devices.

How should we feel about that?

Police in Baton Rouge say they have arrested three people who stole guns with the goal of killing police officers. They are still looking for a fourth suspect in the alleged plot, NPR's Greg Allen reports.

"Police say the thefts were at a Baton Rouge pawn shop early Saturday morning," Greg says. "One person was arrested at the scene. Since then, two others have been arrested and six of the eight stolen handguns have been recovered. Police are still looking for one other man."

A 13-year-old boy is among those arrested, Greg says.

In Animal Kingdom, Voting Of A Different Sort Reigns

Oct 24, 2012
Originally published on October 25, 2012 9:57 am

As part of NPR's coverage of this year's presidential election, All Things Considered asked three science reporters to weigh in on the race. The result is a three-part series on the science of leadership. In Part 1, Alix Spiegel looked at the personalities of American presidents.

Voters could learn some things about choosing a leader from a fish. Or a chimp. Or an elephant.

That's because the animal kingdom, despite its name, tends to operate more like a democracy, says Iain Couzin, an evolutionary biologist at Princeton University.

"One common property we see in animal groups from schooling fish to flocking birds to primate groups is that they effectively vote to decide where to go and what to do," Couzin says.

When one fish heads toward a potential source of food, the other fish vote with their fins on whether to follow, he says. And this highly democratic process helps animals make decisions as a group that are better than those of any single member.

Successful animal leaders know they can't get too far ahead of their constituents, Couzin says.

"They seem to simply reconcile their own goal-oriented behavior with this tendency to align with others," he says. "Because if you don't tend to be influenced by others, you then leave the group behind, and you may get eaten by predators, or you lose the benefits of group living."

Findings like this are relevant to humans because we carry a lot of evolutionary baggage with us into the voting booth, Couzin says. And when it comes to leadership, he says, we are most like animals that live in groups and depend on cooperation to survive. And these groups tend to pick cooperative leaders.

So what about the idea that it's just the biggest or strongest animal in a group that calls the shots?

It's rarely that simple, says Mark van Vugt, an evolutionary psychologist from the VU University in Amsterdam. Take chimps, for example, he says.

"In chimpanzees, it's not necessarily the physically strongest individual who seizes the control over the group," van Vugt says. "It's usually the more cunning individual, someone who forms his coalitions well."

Animal leadership also demonstrates how groups choose different leaders for different situations, he says. Among elephants, for example, the de facto leader is usually the oldest female. But that can change, van Vugt says.

"When the group is attacked, it might be one of the dominant male members who takes control," he says. "But when it comes to knowledge problems and particularly where to find water, they then turn to the oldest female."

Some animal leaders have traits that voters might wish all human leaders had — like unfailing honesty, van Vugt says.

Honeybees are a good example, he says. Their scouts lead by finding a food source and then communicating the location to other bees through something called a waggle dance.

"The interesting thing about it is in the signaling of the scout bees, there is no deception whatsoever," van Vugt says. "They want to do what is best for the hive. And I think that is a little bit dissimilar to humans."

Or chimps, whose leaders are often accomplished liars.

One way animals and people are clearly alike is that both are capable of choosing a bad leader, says Couzin.

"It's not necessarily the most talented or intelligent individual that ends up in a leadership position," Couzin says. Unqualified animals sometimes rise to power, he says, but most of the time they don't last long.

And animals don't wait for the next election to find a replacement, Couzin says.

MELISSA BLOCK, HOST:

With two weeks ago before the election, we are asking a simple question: what makes a good leader? We could measure the candidates based on politics and past performance. This week, though, we're taking a different view of that question through the prism of science.

NPR science correspondents Jon Hamilton often looks at things from an evolutionary point of view, and he found that American voters could learn a thing or two about picking leaders by studying fish, and or chimpanzees or elephants.

JON HAMIILTON, BYLINE: It's called the animal kingdom, but Iain Couzin of Princeton University says most animals live in something closer to a democracy.

IAIN COUZIN: One common property we see in animal groups, from schooling fish to flocking birds to primate groups, is that they effectively vote to decide where to go and what to do.

HAMIILTON: When one fish heads for a potential source of food, the other fish vote with their fins on whether to follow. Couzin says his research shows that this highly democratic process helps groups of animals make better decisions than any one member of the group could. He says it also shows that successful animal leaders know that they can't get too far ahead of their constituents.

COUZIN: They seem to simply reconcile their own goal-oriented behavior - you know, I want to move over there - with this local tendency to align with others. Because if you don't tend to be influenced by others, you then leave the group behind and you may get eaten by predators or you lose the benefits of group living.

HAMIILTON: Couzin says these sorts of findings in animals should be of interest to human leaders, because we humans carry a lot of evolutionary baggage with us into the voting booth. He says when it comes to leadership, people are especially similar to animals that live in groups and depend on cooperation to survive. And these groups tend to pick cooperative leaders.

So what about the idea that it's just the biggest or strongest animal in a group that calls the shots? Mark van Vugt, an evolutionary psychologist from the VU University in Amsterdam, says it's rarely that simple. Take chimps, for example.

MARK VAN VUGT: In chimpanzees it's not necessarily the physically strongest individual who seizes the control over the group, who becomes the alpha, it's usually the more cunning individual; someone who forms his coalitions well and picks a partner who, together with him, they can overthrow the alpha.

HAMIILTON: Van Vugt says animal leadership also demonstrates how groups choose different leaders for different situations. In elephants, the de facto leader is usually the oldest female. But van Vugt says that can change.

VUGT: When the group is attacked, it may not be the oldest female who takes control. It might be like one of the dominant male members, if you like. But when it comes to knowledge problems, and particularly where to find water, they then turn to the oldest female.

HAMIILTON: Van Vugt says some animal leaders have traits we wish all human leaders had, like unfailing honesty. He says honeybees are a good example. Their scouts lead by finding a food source and then communicating the location to other bees, through something called a waggle dance.

VUGT: The interesting thing about it is in the signaling of the scout bees there is no deception whatsoever. I mean, they want to do what is best for the hive. And I think that is a little bit dissimilar to humans.

HAMIILTON: Or chimps, whose leaders are often accomplished liars.

Iain Couzin at Princeton says one way animals and people are clearly alike is that both are capable of choosing a bad leader.

COUZIN: It's not necessarily the most talented or intelligent individual that ends up in a leadership position. There can be this temporary, a sort of rise of power of an individual.

HAMIILTON: Temporary because bad leadership doesn't tend to last too long.

COUZIN: Typically in animals, if this person doesn't have substance behind what they're saying, then they will end up losing out in the longer term.

HAMIILTON: And animals don't wait for the next election to find a better choice. Jon Hamilton, NPR News.
