“The Lions Mane Jellyfish is the largest jellyfish in the world. They have been swimming in arctic waters since before the dinosaurs (over 650 million years ago) and are among some of the oldest surviving species in the world. The largest can come in at about 6 meters and has tentacles over 50 meters long.”

In response to this terrible post.
Please excuse the terrible quality in comparison. I’m not a graphic designer.
Bridging the Zap
When very high voltages are applied to water in two adjacent beakers, they spontaneously form a “water bridge”. It’s a phenomena that, despite being known for more than 100 years, is not completely understood to this day. It is thought that the extreme voltages, in the thousands of volts, are able to pull the positive and negative charges of the water apart in a way that the thread can overcome gravity.

Productivity is really about how you and your brain work. Gregory Ciotti’s collaboration with ASAPScience yields a fascinating video on the science of productivity, giving a quick look at willpower, energy management, and effective work habits like documenting your progress.
Happy new year! For all of you under 23 (born after 1987) this is their first year with all different digits, just another stupid ephemeris.
Some interesting links about the science of fireworks:
only orbit I’m doing is around you
entangling doesn’t only occur at the quantum level, I do say
those relativistic motions attract me ever so
you make me feel like cholorophyll the way I urge your luminous energy
I wonder what’s the name of this heavenly body
The ‘e-volo’ multicopter is a prototype personal transport vehicle, steerable via joystock and powered by sixteen propellers to hover in the air. a team of german professionals— physicist Thomas Senkel, programmer Stephan Wolf, and designer Philipp Halisch, as well as Alexander Zosel— have just completed the first prototype and test flight of the craft, which they imagine for use towards entertainment purposes, aerial photography and inspection, and short-distance travel.
A great inspiration for designing your own vehicle and becoming a Transport Engineer.

We’ve talked about aeroelastic flutter and the demise of the Tacoma Narrows Bridge before, but this explanation from Minute Physics does a nice job of outlining the process simply. As noted in the video, the common explanation of resonance is inaccurate because the wind was constant, so there was no driving frequency for the system. (In contrast, consider vibrating a fluid where the response of the fluid depends on the frequency of the vibrations. This is resonance.) Instead the constant wind supplied energy that fed the natural frequencies of the structure such that an uncontrolled excitation built up. (Video credit: Minute Physics)

Most dogs who went to space didn’t make it back. A moment of silence please. But at least they went into orbit they got to wear special suits; here’s what they looked like.
Dogs are awesome enough on Earth, and probably even more awesome in space. Too bad the suits they were issued by their Soviet handlers are kind of creepy (and would make it pretty hard to play fetch). As would that whole zero gravity thing. But I imagine hanging out with dog swimming around in the air would be pretty incredible on its own.
The DNA Replication Complex, an assembly of proteins that synthesizes new DNA before cell division. It consists of Helicase, Primase, Single-strand binding proteins, and DNA polymerase III. Because DNA strands can only be copied in one direction, the complex must pull out loops of one strand and replicate it in fragments. At this moment there are hundreds of trillions of these molecular machines in constant activity within your body.

Artist Sachiko Kodama is known for her mesmerizing ferrofluid sculptures. Ferrofluids are a colloidal liquid consisting of nanoscale ferromagnetic particles and a carrier fluid such as water or oil. They can react strongly to magnetic fields, forming spikes, brain-like whorls, and even labyrinths. (Photo credits: Sachiko Kodama; via freshphotons)
