Clingy Drones

Vice News’ Motherboard reports that a new type of drone has successfully been designed by researchers at the Createk Design Lab at the University of Sherbrooke in Quebec that can semi-autonomously alight on, and cling to, vertical surfaces, both hard and soft.

Besides obvious spy applications which were not intentionally part of the design process, the researchers suggest that the drone can be used to survey areas damaged by earthquakes, or inspect tall structures that are difficult to get to.

 

Zealandia

Recently, a team of eleven geologists strongly recommended that the sunken land mass between Australia and New Zealand, called Zeelandia, be declared a full (as opposed to mini) continent.

Zealandia was completely submerged until about 23 million years ago, when New Zealand, the French territory of New Caledonia, and assorted islands began popping out of the sea.

If the gelogists recommendation flies, we will have eight continents, instead of the seven we learned in grammar school.

 

Matter Matter Everywhere

Science Daily reports that scientists may have finally determined the reason why matter dominates our Universe, and why we are actually here.

In physics there is a kind of symmetry called CP (shorthand for charge parity), and it has been thought for some time that this symmetry might be violated for a certain subatomic process called neutrino oscillation.

Neutrinos come in three varieties (or flavors) depending on what lightly massive particle the neutrino is paired with.  There is a neutrino for electrons, one for muons, and one for tauons, and as odd as it sounds, as these neutrinos fly through space, they repeatedly change (or oscillate) from one neutrino kind to another.

Maintaining CP symmetry would require that these neutrino oscillations be exactly mirrored by their antiparticle cousins (for example an electron antineutrino), but recent work in Japan strongly suggests that this is not the case.

The above video is a nice introduction to neutrinos and how we detect their existence.

Stay tuned: some folks might soon be winning a Nobel prize in physics for this work.

 

 Job Opening

This week featured a bizarre and somewhat amusing story about a job opening at NASA for “planetary protection officer”, with annual pay of about $187K.  A nine year old boy was an early applicant for the job.

The job is not about protecting Earth from an invasion of ruthless space aliens, but is instead all about keeping the Earth, and solar system places NASA space probes visit, biologically separated.  What NASA doesn’t want under any circumstances is to bring Earth bacteria (and other living stuff) to (say) Mars, or vice versa.

This way Earth would not inadvertently be biologically injured by life from outside Earth, or vice versa.  Such life might be so different that Earth life might be literally defenseless.

You have until August 14th to apply for the position.

 

Mars Or Bust

Elon Musk of Space X is determined to get to Mars, and soon, and like his work with electric cars, he cannot be faulted for lack of vision.

The video above shows an ingenious system for sending a proto-colony of 100 brave souls to the red planet in a time frame of about 10 years.

Powered by 42 newly designed Raptor engines, our pioneers will have to wait in orbit a while before taking off for Mars, as the original booster rockets needs to come back a few times to refuel the mother ship for the long (roughly three month) journey ahead.

As a first step, Space X expects to send a Dragon cargo ship to Mars sometime in 2018, so stay tuned.

But don’t worry, Dave Chapelle is on the job:
