Yes, Rockets CAN Fly in a Vacuum

By Amy Shira Teitel | February 25, 2018 4:56 pm

“Rockets can’t fly in space! There’s no air for the engine to burn in space! And there’s no air for the rocket to push against in space! WE’VE NEVER LEFT EARTH!”

So goes the cry of people who don’t believe we landed on the Moon — at least, this is one of their claims. But it’s wrong. In spite of what they think, rockets can and do fly in a vacuum. Fuel and oxidizer mix and ignite in a combustion chamber causing a controlled explosion that is directed out through the engi …

Fishing activities take up four times as much area as agriculture—and can now be monitored in real time

By Tom Yulsman | February 25, 2018 1:24 pm

The global footprint of fishing is even bigger than expected. But a novel monitoring tool could help put it on a more sustainable path.

To satisfy our hunger, we humans catch something on the order of one trillion fish ever year — a yield that amounts to more than 90 million tons of animal flesh.

We’re clearly the top predator of the seas. But just how much of the oceans are being fished at an industrial scale, what are the patterns, and how are they changing over time? Answering …


About that New Antidepressant Study

By Neuroskeptic | February 24, 2018 7:52 am

A new Lancet paper about antidepressants caused quite a stir this week. Headlines proclaimed that “It’s official – antidepressants work”, “Study proves anti-depressants are effective”, and “Antidepressants work. Period.”


The truth is that while the Lancet paper is a nice piece of work, it tells us very little that we didn’t already know, and it has a number of limitations. The media reaction to the paper is frankly bananas, as we’ll see below.

Here’s why the new study doesn’t t …


Your Weekly Attenborough: Palaina attenboroughi

By Nathaniel Scharping | February 23, 2018 5:17 pm

It should have been their big break. By all rights, the crown was theirs, won with years of blood, sweat and slime. Maybe, in some far-distant astral plane where justice matters, they’re the rightful victors.

But the history books are closed now. Palaina attenboroughi, the second snail to be named after David Attenborough in 2017, was a murmur that never became a shout.

The fame, the media frenzy, the glamour shots — the spoils of victory are all too obvious. And Attenborougharion …

Making the Case Against Plastic Straws

By Eric Betz | February 23, 2018 4:42 pm

Walk the remote shores of the Great Lakes, far outside the city, and you’ll find miles of sandy beaches and quiet tranquility. You’ll also find plastic straws. Pink ones, white ones, clear ones. They’re everywhere.

In fact, visit any coastline around the world and you’re likely to find plastic straws. Conservation groups highlight them as one of the items most frequently collected during beach clean ups.

The reason isn’t hard to grasp. Whether you order an iced coffee or a Co …

Chemists Forge Custom Molecules Upon 'Diamond Anvils'

By Bill Andrews | February 23, 2018 12:03 pm

Chemistry, Walter White once said, is the study of change. Apply the right combination of materials and heat, electricity, or light — some kind of energy — and the results can literally be explosive.

In their quest to manipulate matter, scientists have explored different ways of poking molecules to see how they react. According to a paper that appeared in the journal Nature this week, they’ve found a new one, and possibly the most cartoonish one yet: using tiny anvils to literally b …

How To Make a Monkey an Adidas Fan? Sex and Celebrity

By Nathaniel Scharping | February 23, 2018 11:36 am

We’re no better than monkeys when it comes to advertising. Or, perhaps it’s better said that they’re no better than us.

In a clever study, researchers showed rhesus macaques brand logos (which were just random images to them) paired with a picture of either a high-status male monkey, a low-status male monkey, or female monkey genitals to see if they could elicit preferences in them. In short, they were trying out one of the oldest tricks in the advertising world — selling products wi …

From Painters to Potters, Scientists Stage an Online Art Show

By Elizabeth Preston | February 23, 2018 10:03 am

On January 24, University of British Columbia geneticist Dave Ng tweeted, “It’s always interesting to me how kids react when they find out I’m a scientist who also does artistic things (like they can’t co-exist or something). Would love to start a thread where other scientists share their artistic tendencies. #scienceartmix.”

Ng posted some of his own visual art and writing, and invited others to chime in. Musicians, painters, dancers and more eagerly joined the dataset.

Seriously, Science?

Flashback Friday: Android vs. iPhone: what your phone choice says about you.

By Seriously Science | February 23, 2018 6:00 am

Given all the money spent on advertising, it’s no wonder there are stereotypes about iPhone and Android users. But are these real? Is there anything you can predict about me just from knowing whether I use an iPhone or Android (and vice versa – can you predict my phone choice from my personality)? Well, according to these researchers, there really are population differences between iPhone and Android users: if I told them I used an iPhone, they would guess that I’m younger, female, and …

Watch: Not just one but TWO hurricane-force storms swirling in the North Atlantic Ocean

By Tom Yulsman | February 22, 2018 8:51 pm

In recent days, two powerful storms packing hurricane-force winds have spun up in the North Atlantic. You can watch them in the animation above of GOES-16 satellite imagery. It was posted to the awesome GOES-16 Loop of the Day website.

The storm closer to North America was so strong that it churned the waters up into stupendous waves higher than 60 feet tall:

That would be almost high enough to inundate the White House.
