3 Reasons Octopus Locomotion Is the Weirdest

by Elizabeth Preston in Inkfish



Of course there's nothing ordinary about an octopus. It's the animal that showed us spinelessness doesn't have to mean a lack of smarts. But when researchers brought some octopuses into the lab to study exactly how the animals move, their findings were bizarre—both predictably and unpredictably.

Scientists at the Hebrew University of Jerusalem studied nine common octopuses (Octopus vulgaris) that fishers had scooped out of the ocean for them. Once the animals got comfortable in the lab, t........ Read more »

this is your brain on cosmic rays

by Greg Fish in weird things

Back in the day, I argued that if we were going to get serious about space exploration, we also had to budget for large, luxury spacecraft rather than just capsules in which we would cram the brave men and women we’d be sending to other worlds with a pat on the back for agreeing to deal with the discomfort and damage to their bodies. Among the reasons listed were the basic physiological problems of spending many months in zero gravity, and mental health hazards of boredom and cabin fever. ........ Read more »

NASA and warp drive: An update

by Marco Frasca in The Gauge Connection

There is some excitement in the net about some news of Harold White’s experiment at NASA. I have uncovered it by chance at a forum. This is a well-frequented site with people at NASA posting on it and regularly updating about the work that they are carrying out. You can also have noticed some activity […]... Read more »

of microwave noodles and extragalactic signals

by Greg Fish in weird things

FRBs just can’t seem to catch a break this month. First, they were an alien signal. Then just as quickly as they were attributed to aliens because the Daily Fail decided to get creative with two out of context words and no one seemed to bother to fact check them, the bursts were called a false signal caused by microwave interference. Not just any microwave interference mind you, but the kind in which you warm up leftovers [...]... Read more »

why the great void didn’t cause the cold spot

by Greg Fish in weird things

Remember the anomalous Cold Spot, the bizarre, low temperature area spotted in the maps of the Cosmic Microwave Background Radiation, or CMBR for short, the echo the Big Bang which gives us a very high level overview of the structure of our universe? Cosmologists bristled at an anomaly stretching some 1.8 billion light years and seemingly violating what we thought was a universal rule [...]... Read more »

peeking at dark matter during a tidal strip show

by Greg Fish in weird things

Dark matter is a substance that makes up nearly all mass in the universe, but decades after we discovered it, all we have are indirect measurements which show us that it’s there in very large amounts, forming galactic halos, but ultimately, little else. It doesn’t seem to interact with any of the stuff that makes stars, dust, and planets, it emits or reflects no radiation, and this utter lack of interesting properties we could study [...]...

Black hole hunters tackle a cosmic conundrum

by Dr. Jekyll in Lunatic Laboratories

While mass media was busy misquoting Stephen Hawking and arguing about black holes, astrophysicists have been hard at work trying to solve still unanswered questions about them. Now a team has not only proven that a supermassive black hole exists in a place where it isn’t supposed to be, but in doing so have opened a new door to what things were like in the early universe....

A glass fiber that brings light to a standstill

by Dr. Jekyll in Lunatic Laboratories

Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved – not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today....

The universe is expanding, but how fast?

by Dr. Jekyll in Lunatic Laboratories

We are expanding, well more accurately the universe is expanding. However researchers have found certain types of supernovae, or exploding stars, are more diverse than previously thought. The results have implications for big cosmological questions, such as how fast the universe has been expanding since the Big Bang. Most importantly, the findings hint at the possibility that the acceleration of the expansion of the universe might not be quite as fast as textbooks say.... Read more »

Star Trek Shields For Tanks

by Mark E. Lasbury in The 'Scope

Star Trek deflectors absorbed or deflected energy beams, but would they work against bullets or asteroids? Scientists are on working on armors and plasma systems that can stop projectiles. In some cases we use explosions to stop explosions. In others, tanks are turned into electrical pulse generators that zap incoming rockets. But the most amazing is the wall of exploding plasma that will be the first true defensive energy shield.... Read more »

That Higgs is trivial!

by Marco Frasca in The Gauge Connection

Notwithstanding LHC has seen the particle, the Higgs sector of the Standard Model has some serious problems. This fact yielded more than one headache to physicists. One of these difficulties is called technically “triviality“. The scalar field theory, that is so well defined classically, does not exist as a quantum field theory unless is non-interacting. […]...
