The Nengo Neural Simulator

The Nengo Neural Simulator

Nengo is a graphical and scripting based Python package for simulating large-scale neural networks. Nengo can create sophisticated spiking or non-spiking neural simulations with sensible defaults in a few lines of code. Yet, Nengo is highly extensible and flexible.

Mice with 3D-Printed Ovaries Successfully Give Birth

AsKatherine Kornei at Science reports,the researchers used a 3D printer to build the scaffolding of the organs, weaving layers of gelatin to createtiny (15 x 15 millimeter) ovaries on glass slides. They then tested the scaffolds by embedding a follicle—the tiny sacs composed of hormone-secreting cells that containthe maturing eggs. This test suggested that the tightest weave supported the highest survival rates, reports Kornei.

How much of the Internet is using QUIC?

How much of the Internet is using QUIC?

It’s been five years since Google launched QUIC — a new transport protocol that is deployed on the shoulders of UDP in user space. QUIC offers similar properties as TCP + TLS 1.3 but promises to incorporate new features more easily and without them being dropped by legacy systems that don’t support them, for example, middleboxes that block new TCP features — a problem that TCP has faced since its initial deployment. QUIC tackles the problem by offering a fully encrypted transport protocol, thereby removing the possibility for middleboxes to alter its content.

Forget carbon fiber—we can now make carbon nanotube fibers

Forget carbon fiber—we can now make carbon nanotube fibers

A carbon nanotube is tough—by some measures, more than 30 times more robust than Kevlar. As they’re only a few atoms thick, however, that toughness isn’t especially useful. Attempts have been made to bundle them together, but nothing has worked out especially well; the individual nanotubes are typically short, and it’s difficult to get them to all line up in the same direction.

Short Circuit: The High Cost of Electric Vehicle Subsidies

Short Circuit: The High Cost of Electric Vehicle Subsidies

Many claim that “zero-emissions vehicles” (ZEVs), especially battery-powered electric vehicles, should replace most, if not all, cars and trucks powered by gasoline-burning internal combustion engines. The primary rationale is to reduce air pollution and carbon dioxide (CO2) emissions. To effect this change, governments are spending billions of dollars to subsidize electric vehicles.
