This is SCIENCE FRIDAY, I'm Ira Flatow. Powerful storms this spring: tornadoes like the ones in Oklahoma have caused damage estimated in the billions of dollars and dozens of deaths. But does the destruction have to be so devastating? What are the engineering challenges to designing and building stronger, more tornado-resistant structures and providing better protection for the people who live there?
This is SCIENCE FRIDAY; I'm Ira Flatow. If you're thinking about getting married or having children or just contemplating your health care options, you or your doctor may decide to have your DNA analyzed, looking for genes that may indicate possible trouble ahead. Maybe there's a telltale mutation hiding there or a recognizable pattern of genes.
Many people associate France today with the production of great wines. But winemaking isn't native to the French. Patrick McGovern, an archaeologist of fermented beverages, has dated the beginning of viniculture in France to around 500 B.C. and contact with the Etruscans.
This is SCIENCE FRIDAY. I'm Ira Flatow. Up next, surviving the big one, and I mean a really big one. As any fan of dinosaurs knows, extinction happens. The Earth isn't immune to assaults. You've got your asteroids, your volcanic eruptions, events that cause so much disruption to the environment that eventually life or most of life is wiped out.
Singer Justin Bieber is the latest celebrity to score a booking on Virgin Galactic's SpaceShipTwo, destined for its first suborbital test flight sometime this year.
The Bieb and manager Scooter Braun join the likes of Ashton Kutcher, Leonardo DiCaprio and Angelina Jolie on the elite passenger list of those willing and able to pay $250,000 for a seat on Richard Branson's commercial space-flight venture.
Tossing out food is clearly a waste of money — and maybe even immoral, according to Pope Francis, who on Wednesday likened food waste to "stealing from the table of those who are poor and hungry." And as we've reported, you also may be creating extra greenhouse gas emissions by sending food to
The case of a Pennsylvania girl who is dying from cystic fibrosis has sparked an emotional debate over how the nation allocates lungs for transplantation.
Ten-year-old Sarah Murnaghan is in intensive care at Children's Hospital of Philadelphia awaiting a lung transplant. Under the current rules, lungs from adults are offered to other adults and adolescents before being offered to children younger than 12.
Thierry Chopin from the University of New Brunswick examines a raft that holds strings of seaweed. The seaweed grows around pens of farmed salmon and soaks up some of the nutrients that would otherwise pollute the Bay of Fundy.

Mussels thrive on particles that come from fish waste. The mussels help clear the water and reduce the environmental impact of fish farms. Canada's federal food agency has certified them as safe for human consumption.

Thierry Chopin examines two type of seaweed being grown around Cooke Aquaculture's salmon farm. The company sells the seaweed as a specialty food and to a cosmetic company, which extracts natural compounds from it. Chopin is also experimenting with seaweed as a protein supplement for fish meal.

Lenny Totten of Cooke Aquaculture examines a circular raft that holds up hundreds of heavy strings of mussels, which are cultivated for human consumption.
Last month, we told you about companies that are growing salmon on dry land. That's an effective — but expensive — way to reduce water pollution caused by fish farms. After all, marine aquaculture provides about half of the seafood we eat.
In her latest book about Henry Molaison, Corkin tells the story of the amnesic man she studied for a half-century, whose brain helped teach neuroscientists about the distinctions between memory and intellect.

Neuroscientist Suzanne Corkin worked with Henry Gustave Molaison, who had severe amnesia, for 50 years — from the 1953 surgery that caused permanent damage to his brain until his death in 2008.
In 1953, 27-year-old Henry Gustave Molaison underwent an experimental brain surgery in an attempt to alleviate his severe epileptic seizures. The surgery left him with a form of amnesia; he could remember many things from the past, but was unable to form new memories.
"He could tell us about where he was born, [that] his father's family was from Thibodaux, La., his mother came from Ireland," says neuroscientist Suzanne Corkin. "He talked about the towns in Hartford where he lived and about his specific neighbors. He knew the schools he attended, some of his classmates' names."
Here's a sobering thought: Wild birds — including city pigeons and ubiquitous Canada geese — carry 170 different types of bird flu. You know, all those viruses with the Hs and Ns in their names, like H1N1 and H5N1.
Only a dozen of these viruses have infected humans so far, but many of those have been deadly, and three of them have caused global flu pandemics.
Does every bird flu that leaps into people have the potential to turn into the next "big one" that spreads rapidly around the world?
From southern Virginia to New England, lots of people are being treated to a cicada serenade. If these insects sound loud to you, that's because they are. They're so loud that some Navy engineers are trying to borrow their technique.
The origin of the first primates — the group that includes humans, apes and monkeys — is thought to lie in the deep past, about 55 million years ago.
Fossils from that period are rare. But now, there's an exciting new one. It's called Archicebus achilles, roughly meaning "beginning long-tailed monkey." Actually, this creature lived before the monkeys we know of today, a mere 10 million years after the dinosaurs died out.
