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 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."
On Sunday, evolutionary psychologist Geoffrey Miller, a professor currently on leave from the University of New Mexico with a visiting position at New York University, tweeted a comment that sent shock waves through academia and beyond:
Dear obese PhD applicants: if you didn't have the willpower to stop eating carbs, you won't have the willpower to do a dissertation #truth
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?
Two weeks ago, I wrote here about my new cancer diagnosis and my upcoming robot-assisted surgery.
The surgery occurred as planned on May 24; after a single rough night in the hospital, I went home and my recovery has proceeded completely on track (with the usual ups and downs after a 6-hour operation).
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.
Last week NASA scientists put the space telescope Kepler in a kind of technological coma. The craft, designed to search for Earth-like planets orbiting stars in our cosmic neighborhood (within a few thousand light-years, that is), failed and seems to be unfixable. (Hope remains, though.)
