Meet Toxotes jaculatrix, also known as the banded archer fish. Jaculatrix sounds like it would be some kind of S&M thing but it isn’t, it means “thrower” or “caster,” (of darts) and the fish is named thus because it hunts its prey by shooting ‘darts’ of water out of its mouth.
Hi-Resolution simulations show that plumes of magma rising from miles below ground could be responsible for the breakup of continents under special circumstances. Volcanoes are as endlessly fascinating as they are potent forces of nature. Not only can they flood the land with lava and infuse the atmosphere with their gasses; whatever it is that
The biggest (verified) dinosaur to have ever walked the earth is in the news and he has a real cool name, Dreadnoughtus.
The term dreadnought is nostalgic for me since the first time that word came into my ken as a kid, it was referring to a Star Trek ship like the Enterprise but with 3 warp nacelles instead of two. So cool.
In this case, Dreadnoughtus refers to a very special dinosaur discovered in 2005 in Argentina that’s been recently published about in the journal Scientific Reports. Its name means “Fears Nothing” and the researchers based it on the seeming imperviousness and intimidating nature of the revolutionary Dreadnought battleships from a century ago
In preparation for our two SGU recordings at Dragon Con 2014, we had to record episode #477 earlier than normal, almost a week ahead of our usual schedule. Because so much science and skeptic news occurs every day, it means we sometimes miss on some very interesting items which might have otherwise made it to the show. Here’s a small sample of some of the items we might have otherwise covered:
A new study published in the Journal of Climate Science suggests that the risk of a “decade-scale megadrought” in the US Southwest is above 80% and may be as high as 90% in specific areas.
A smallish asteroid (20 meters) will be passing very close to the earth this weekend. We and our satellites are not in danger but 25,000 miles away is uncomfortably close.
The name of this newly discovered asteroid is the unimaginative 2014 RC and was discovered by Arizona’s Catalina Sky Survey and independently a day later by the Pan-STARRS 1 telescope in Hawaii (sorry Hawaii, second doesn’t count).
25,000 miles away may seem like a lot but consider that that’s one tenth the distance to the moon and just slightly farther away than our geosynchronous satellites which are in 22,000 mile high orbits. If that asteroid took out the Netflix satellite I would be supremely pissed.
Your ultimate address just changed. Astronomers have discovered that the supercluster we’ve long-believed our Milky Galaxy resides in is actually just an appendage on the outskirts of an even more giant new supercluster called Laniakea.
Every now and then we receive an email from someone who lists their address in a much more complete way than most everyone else does. Instead of listing something like a town/state/country, they take a humorous much broader perspective that would seemingly be of interest only to an alien from the other side of the visible universe. They usually take the form of:
Earth/Milky Way/Local Group/Virgo-Cluster/Virgo-SuperCluster/Visible Universe.
