Tuesday in Phoenix, Arizona, the temperature kept some planes grounded.
Phoenix was projected to reach of 120 degrees Fahrenheit, a near-record for the desert city, and hot enough that small planes cannot generate enough lift to fly. Phoenix and other cities have experienced similar conditions before, but only rarely—for now. The grounded passengers got to sit inside an air-conditioned terminal, at least. But in other parts of the world where temperatures are set t ...read more
Donn Eisele on board Apollo 7. NASA.
There are some astronauts we know a lot about, or at least whose names are familiar, like Neil or Buzz (as in Armstrong and Aldrin, the first men on the Moon). More nerdy space fans will also recognize the names Gene and Pete (as is Cenan and Conrad). But what about Donn, is Eisele? Donn Eisele — whose last name is pronounced Eyes-lee, not Eye-zell — is a fascinating character who flew on the first Apollo mission but most people have never heard ...read more

Sometimes you run across a grimy, tattered dollar bill that seems like it’s been around since the beginning of time. Assuredly it hasn’t, but the history of human beings using cash currency does go back a long time – 40,000 years.
Scientists have tracked exchange and trade through the archaeological record, starting in Upper Paleolithic when groups of hunters traded for the best flint weapons and other tools. First, people bartered, making direct deals ...read more

Four years ago a citizen science game called Eyewire hatched from Seung Lab, then at MIT and now at Princeton. Its goal was to pair up gamers with a challenge that has been bottlenecking neuroscience for decades: mapping the brain. Over the years the project grew. Hundreds of thousands of people helped, enabling new discoveries and stunning visualizations of neurons.

Media coverage of scientific retractions risks feeding a narrative that academic science is broken – a narrative which plays into the hands of those who want to cut science funding and ignore scientific advice.
So say Joseph Hilgard and Kathleen Hall Jamieson in a book chapter called Science as “Broken” Versus Science as “Self-Correcting”: How Retractions and Peer-Review Problems Are Exploited to Attack Science
Hilgard and Jamieson discuss two retraction scandals ...read more

If you smoke cigarettes, you’re putting yourself at a heightened risk for heart disease. That correlation is well-known and unchallenged today, but that wasn’t always so. It took an ambitious, years-long project, the Framingham Heart Study to uncover the link, and it only happened because of the study’s commitment to comprehensive data collection.
The Framingham study is a near-canonical example of the power of longitudinal studies, those tha ...read more

Physicists aren’t often reprimanded for using risqué humor in their academic writings, but in 1991 that is exactly what happened to the cosmologist Andrei Linde at Stanford University. He had submitted a draft article entitled ‘Hard Art of the Universe Creation’ to the journal Nuclear Physics B. In it, he outlined the possibility of creating a universe in a laboratory: a whole new cosmos that might one day evolve its own stars, planets and intell ...read more
A new study fills gaps in the when and where of cat domestication, explaining how the animals went from lean hunters to, uh, this. (Credit G. Tarlach…yes, it’s my cat, but don’t kvetch about his obesity. I took the photo shortly after I adopted him. Thanks to careful management he is now several pounds lighter.)
The truth about cats and dogs is this: despite being the two species that humans are most likely to have as pets, Rex and Ruffles had very different paths from t ...read more
