Scientists are studying evolutionary concepts with robot mice

Studying evolution is tricky -- it's a process that happens over countless generations and thousands of years, but the men tasked with studying it live less than a century. Researchers at the Okinawa Institute of Science and Technology have found one way around the problem: robots. OIST's Dr. Stefan Elfwing has been using small, rodent-like robots to study the long-term effects of disparate mating strategies, observing the evolution of the simulated species for over 1,000 generations. Two groups of robo-mice were programmed to forage for food (battery-powered recharge stations) and to find a mate (trade data through an embedded IR port), with each group following a different mating strategy. Robots dubbed "foragers" would focus on recharging, only mating if it didn't get in the way of feeding, while "trackers" would actively seek mates and go without charging if it increased their chances of linking up IR ports.

The experiment eventually yielded a population with both phenotypes, mirroring populations of real species with similarly distinct mating strategies -- which shows that robot simulations are a viable way to study long-term evolutionary concepts. Wondering what Elfwing's biological conclusions were? No worries, you can find the formal results of his research

Exotic hadron particles: Scientists at CERN have confirmed the detection of exotic hadrons, a type of matter whose existence is not predicted by the Standard Model of particle physics.

The new particle is about four times more massive than a proton, has a negative charge, and appears to be a theoretical particle known as a tetraquark. The results are still young, but if this discovery holds up it could have implications for our understanding of neutron stars.
Physicists working at the Large Hadron Collider have spotted a long sought-after exotic particle that's the strongest evidence yet for a new form of matter called a tetraquark. Here's what the discovery could mean to astrophysics.

 Titan Aerospace makes drones which can stay aloft for extended periods of time.  The drones which fly well above the altitude where commercial aircraft fly and below where satellites orbit, can beam an internet signal from space.  But for Google, this may be about more than just internet, as the drones may also be useful in Google’s mapping services.  If Google can operate its own atmospheric drones, it will be the equivalent to them operating their own satellites, which means more rapid updates to Google Maps and Google Earth with near real-time information such as weather updates.
Google has acquired Titan Aerospace, a company originally sought by Facebook as a means to bring internet to remote parts of the globe.  Titan Aerospace makes drones which can stay aloft for extended periods of time.  The drones which fly well above the altitude where commercial aircraft fly and below [...]

Researchers use common spray gun to create self-assembling nanoparticle films

The promise of nanoparticles stems from their potential to modify the physical and mechanical properties of polymers for diverse applications, such as photovoltaic cells, sensors, and separation membranes. Methods currently used to create desired nanostructure, however, rely on complex and energy-intensive techniques, such as layer-by-layer or patterning approaches, which are limited in scale and often have poor stability.

Publishing in Nature Communications, Dr. Minhao Wong, a former graduate research assistant in the Polymer Technology Center of Dr. H-J Sue, Department of Materials Science and Engineering, and Dr. Ryohei Ishige of I2CNER (International Institute for Carbon-Neutral Energy Research), Kyushu University in Japan, have developed a simple approach of applying a surface coating of thin, flat nanoplatelets using a common spray gun, such as can be purchased off-the-shelf from an art supply store, to create a surface coating in which nanoplatelets spontaneously self-assemble into "nano-walls." The nano-walls act as rigid barriers that prevent oxygen gas from reaching the surface, and are effective at low and high humidity levels.

Best short description of homotopy type theory I've seen:

"Around 2005, Voevodsky, and independently Steve Awodey and Michael Warren, realized that constructive dependent type theory, the axiomatic basis for Coq, has an unexpected homotopy-theoretic interpretation. ... What Voevodsky, Awodey, and Warren realized is that one can view dependent type theory as a calculus of topological spaces and continuous maps between them, wherein the assertion x = y is interpreted as the existence of a path between x and y. More specifically, Voevodsky showed there is a model of constructive type theory in the category of simplicial sets, a mathematical structure well known to algebraic topologists."
