5:38 PM | New evidence for a massive flood on the Mackenzie River 13,000 years ago
The Northern Hemisphere suddenly cooled about 12,800 years ago in an event named the Younger Dryas. Scientists have debated the cause for many years. One widely-believed explanation is that the massive but long gone Lake Agassiz in central Canada rapidly flooded fresh water east down the St. Lawrence River into the northern Atlantic Ocean. That pulse of fresh water interfered with warm ocean currents and triggered the cooling.

5:03 PM | An updated geological timeline for the extinction of the dinosaurs
The asteroid that smashed into the Yucatan Peninsula a little more than 66 million years ago left behind the Chicxulub crater, but it also left behind something else: iridium, a rare element, which settled in a fine layer all over the world. When scientists discovered this layer between rock strata in the 1980s, it eventually led them to the crater as well, and an explanation for the disappearance of the dinosaurs. But on either side of that layer, which serves as a geological boundary between […]

4:15 PM | Dark Sky in Canarias
Because why not, here’s a luscious time-lapse animation of the sky over La Palma, Tenerife, and El Hierro, three of the Canary Islands off the coast of Morocco: This video was taken by photographer Imanol Mujika. He has a stunning Flickr gallery, too. I’ve been to La Palma, and the clouds really do roll in like that. I like how you can see them swell and disappear over the city (I think it’s Santa Cruz in the video) like waves on a beach. Also, toward the end (at the 1:55 […]

12:15 PM | Hour by Hour, the Phases of the Moon for the Entire Year of 2015
Just the other day I wrote about the good folks who create video at NASA’s Goddard Space Flight Center. And now I get to do it again: They just released their Dial-A-Moon page for 2015, which lets you display the hour-by-hour appearance of the moon for the entire year. They also put out a video compiling all the images for the year into a single animation. You might expect it to look like the Moon is just sitting there, with the phase changing as the terminator (the day/night line) […]

11:57 AM | Auld Lang Syne: May We Look Back at our Present Endeavors in Space with Pride
When the first humans venture beyond the Solar System, our present-day experiences with the Voyager and Pioneer craft will be remembered as watershed moments. Our space craft presently experience a space environment that would harm human tissue and would dampen the spirits of the hardiest souls. The specific case is how Coronal Mass Ejections of […]

10:47 AM | A 3D Harmonograph
I posted this on GitHub some time ago, and forgot to post about it here. So here it is now. The idea is simple enough: harmonographs are just graphical representations of the sums of the motions of 2 or more pendulums on the 2D plane, such as a piece of paper, just as you see… Read more → The post A 3D Harmonograph appeared first on Tuxar.uk.

9:00 AM | Guest Post: The Art of Losing Paperclips
Not long ago, walking past some court buildings with a friend, I kept stopping to pick up paper clips. Besides the usual little Gem clips, like ACCO Brand Trombones No 1, I found a black-and-silver binder clip and a rare angel-shaped “ideal clamp”–all of them no doubt carelessly dropped by lawyers who once used them […]

5:00 AM | Siamo vicini alla scoperta della vita extraterrestre?
Che cosa cercano gli scienziati quando vanno alla ricerca di vita aliena? Molto! La ricerca della vita extraterrestre richiede l’aiuto di astronomi, scienziati planetari, chimici, genetisti, per citarne alcuni. La domanda è: stiamo forse guardano nel posto sbagliato? Può la vita svilupparsi in altri modi che non abbiamo mai immaginato? In questo video, che fa … Continue reading Siamo vicini alla scoperta della vita extraterrestre? →

4:37 AM | You Could Name a Crater on the Planet Mercury
The team of scientists and educators behind the Messenger spacecraft orbiting the planet Mercury is giving the public the chance to nominate artists, writers, or composers whose names deserve to be on one of five craters on the hot little planet closest to the Sun. There have been a number of publicity campaigns recently that deal with naming things, but this one is the real thing. By international agreement, the naming of worlds and features in space is done by a special committee of […]

2:41 AM | Long-lived lightning clusters in hotspots worldwide
Most lightning hits as a short-lived luminosity, a flickering flash in the pan. Other lightning lingers 10 to 100 times as long. It can simmer the sap of an entire tree and spark a dangerous forest fire. Now, researchers at the University of Alabama in Huntsville have identified hotspots worldwide where long-lived lightning clusters occur.

12:38 AM | The Big Bang for Children (Synopsis)
“To begin, begin.” -William Wordsworth Is the Big Bang the greatest scientific achievement of the 20th century? I — along with many others — would argue that it is. It’s something that even young children are curious about! Perhaps it’s in our nature to wonder about where we come from? Yet despite the fact that it’s been…

11:25 PM | Scientists use satellites to monitor volcano risks
A NASA team utilized satellite data to create a map of past volcanic deposits and modeled the risk to nearby towns. They found one town on a potential lava flow path and a second town at risk for mud flows. The results were presented at Monday’s poster session at the American Geophysical Union’s Fall Meeting. The group’s methodology using satellite images can serve as a template for remotely assessing volcano risk, according to the researchers.

11:15 PM | Researchers keep an eye on walrus ice preferences
To walruses, ice means life. It’s their home base, their mating ground, and their transportation. As climate change threatens the extent of ocean ice, a new study takes a first step at determining how changing ice conditions are influencing walrus dynamics.

10:02 PM | Scientists use drones to monitor surf zone
When ocean scientists visit the beach they pack more than sunscreen and a towel – they pack drones. Researchers show in a new study that drones can be used to cheaply and accurately monitor the movement of water in the surf zone in the Gulf of Mexico. The drones provide a new way of documenting the movement of plant and animal plankton, sediments and pollutants, including spilled oil, near the shore.
