Russia isn’t messing around.

It’s for a good cause — but you have good reason to be scared.

Membrane wings show promise for highly efficient micro air vehicles.

Astronomers have found an extraordinary trail of gas greater than 300,000 light years across originating from a nearby galaxy called NGC 4569, according to a report in Astronomy & Astrophysics.

The tail is comprised of hydrogen gas, the material new stars are born from, and is five times longer than the galaxy itself.

Brings a lot of possibilities.

Robotic reasoning.

Paper demonstrates autonomous underwater vehicles can be pre-programmed to make independent decisions.

Physicists have zoomed in on the transition that could explain why copper-oxides have such impressive superconducting powers.

Settling a 20-year debate in the field, they found that a mysterious quantum phase transition associated with the termination of a regime called the “pseudogap” causes a sharp drop in the number of conducting electrons available to pair up for superconductivity. The team hypothesizes that whatever is happening at this point is probably the reason that cuprates support superconductivity at much higher temperatures than other materials—about half way to room temperature.

“It’s very likely that the reason superconductivity grows in the first place, and the reason it grows so strongly, is because of that critical point,” CIFAR Senior Fellow Louis Taillefer (Université de Sherbrooke) says. The new findings are published in Nature.

3D Printing hazardous to the environment due to toxins.

Three-dimensional (3D) printing, also known as additive manufacturing, refers to those technologies capable of developing 3D objects from raw materials, like metals and polymers based on computerized 3D parametric models.

Breaking the bacteria barriers.

If that field is at just the right magnitude, it will open up pores within the cell membrane, through which DNA can flow. But it can take scientists months or even years to figure out the exact electric field conditions to reversibly unlock a membrane’s pores.

A new microfluidic device developed by MIT engineers may help scientists quickly home in on the electric field “sweet spot” — the range of electric potentials that will harmlessly and temporarily open up membrane pores to let DNA in. In principle, the simple device could be used on any microorganism or cell, significantly speeding up the first step in genetic engineering.

And act like nothing happened.

New research supports an old, more intuitive theory of how sub-atomic particles behave. Cathal O’Connell explains.
