Just months ago, former President Jimmy Carter announced he had melanoma that had spread to his brain. Recently, however, he made the shocking announcement that he was cancer-free. He owes his condition to a new cancer immunotherapy drug known as Keytruda that is giving researchers, cancer patients and doctors new hope in the war on cancer.

Dr. Antoni Ribas who work on immunotherapy treatments for cancer at UCLA says the idea behind the drug is to use the patient's own immune system to attack the cancer.

What happens when you give scientists comedy improv lessons?

Improv is something you expect to find on Saturday Night Live, not in the science lab. A couple of acting teachers, however, are beginning to introduce improv acting and communication techniques to the science syllabus. “JRN 503: Improvisation for Scientists” is a course now on offer at New York’s Stony Brook University.

Alan Alda is an actor, director, screenwriter and board member for the World Science Festival. He’s also one of the people behind the new improv class for scientists at Stony Brook University in Stony Brook, New York.

Could you explain the electromagnetic spectrum, continental drift, or the basics of nuclear power using just the 1,000 most common English words? That’s the challenge XKCD’s Randall Munroe took on in his latest book, "Thing Explainer: Complicated Stuff in Simple Words."

Munroe has had many different jobs: comic artist, NASA roboticist. Now he has combined his many skills to put out an illustrated book explaining some of the world’s more difficult concepts in simple language.

Are algorithms racist — and can we fix that?

Dec 6, 2015

Some believers in big data have claimed that, in big data sets, “the numbers speak for themselves.” Or in other words, the more data available to them, the closer machines can get to achieving objectivity in their decision-making.

But data researcher Kate Crawford says that’s not always the case. In fact, big data sets can perpetuate the same biases present in our culture, teaching machines to discriminate when scanning resumes or approving loans, for example.

The little-known world of endangered plant poaching

There are plenty of news stories about lions, leopards and elephants being poached, but animals aren’t the only endangered species out there. Rare and protected plants are also harvested by poachers, smuggled across borders and illegally sold online. 

What brainless slime mold can teach us about making better decisions

Nov 30, 2015

There is a mindless, senseless yellow-tinted blob of an organism that lives on the forest floor. It’s called slime mold and even though it lacks a brain, it can be relied upon to make a healthy decision more often than most humans. 

“It lives on the forest floor, and it loves moisture and darkness. And it just meanders around looking for food,” Science Friday video producer Luke Groskin. “It has no eyes, and it can only feel for food. So how does it make a decision? How does that creature decide, ‘Oh, it's time to go over here. It's time to go over there.'”

Scientists say they have a new cure for hearing loss

Jay Alan Zimmerman is a successful composer who writes music for movies and musicals. There's something that sets him apart from other composers, however. He's deaf. 

Zimmerman wasn’t always deaf. He came to New York and began his career in music. Over time he realized he had lost quite a bit of hearing at the top of his range. He didn’t realize just how bad his hearing loss was until one day when he was trying to work on a new track. 

This is a microscopic image of MDMA, the psychoactive drug popularly known as ecstasy, or Molly, that “produces feelings of increased energy, euphoria, emotional warmth and empathy toward others, and distortions in sensory and time perception,” according to the National Institute on Drug Abuse.

The smell inside the warehouse of Nine Pin Ciderworks in Albany, New York, on a recent afternoon was unmistakable: alcohol, with a hint of sweetness.

The aroma wafted from three large plastic vats nearly filled to the brim with the juice of 21,000 pounds of apples recently picked from a nearby orchard. Gurgling loudly, the liquid belched carbon dioxide in a process crucial to turning pure apple juice boozy — fermentation. A gaseous haze hung over the vats at eye level.

The recent attacks in Paris and San Bernardino have reopened the debate over whether the government should have expanded abilities to crack open encrypted messages and access encrypted devices. The director of the FBI in testimony on Capitol Hill this week that messages are going unread, even from those responsible for known attacks.

Two experts, however, say the real problem isn’t lack of access, but lack of analysis. 

After the Paris attacks CIA Director John Brennan warned that encryption could hinder security services from tracking potential dangers.

The Carolina SqiQuarium opened in 2013 as part of expansion plans for the whole Greensboro Science Center. The aquarium features African penguins, sharks, otters and stingrays, among others.

The Greensboro Science Center is the only institution in North Carolina to house a zoo, aquarium and museum under one roof, and it's one of a handful in the country. The Science Center has been in the Triad since the 1950s, but recent expansion has dramatically grown the facility into a true 3-in-1 destination.

The Evolution Of Bats

Scientists have found bat fossils dating back 55 million years ago, but they still do not know the genesis of their evolution. As time passed since those early bats, the animals found little competition during the night and proliferated.

Bats currently comprise 20 percent of all mammals. There are many types of bats, from the insect-eating to the fruit-eating to the blood-sucking vampire bats. These creatures are also the only mammals with powered flight or a sophisticated echolocation system. 

Fosa: King Of The Madagascar Jungle

In the jungles of Madagascar roams an endemic beast known as the fosa. It has the frame of a small cougar and head of a mongoose, hunting any animal with a heartbeat, including lemurs.

Though the fosa rests atop the food chain in Madagascar, slash and burn agriculture threaten the future of this already dwindling population.

Aziz Sancar grew up as a farm boy in a small town in Turkey. He was a bright child and attended medical school. He returned to his hometown and practiced medicine for a few years.

But even in his daily practice, Sancar had questions about how things worked on the molecular level.
