How Fast Is 5G?

Posted by in categories: energy, internet

This video is the first in a two-part series discussing 5G. In this video, we’ll be discussing the many many aspects of current generation mobile networks that 5G is set to improve.

As well as the technologies and communication techniques that will be required to enable these upgrades in speed, latency, bandwidth, energy consumption and more!

[0:35–8:15] First we’ll take a look at the core technologies that 5G is composed of, how they work together and the benefits they will each bring.

Artificial cells are tiny bacteria fighters

Posted by in categories: bioengineering, biotech/medical

“Lego block” artificial cells that can kill bacteria have been created by researchers at the University of California, Davis Department of Biomedical Engineering. The work is reported Aug. 29 in the journal ACS Applied Materials & Interfaces.

“We engineered from the bottom-up – like Lego blocks – to destroy ,” said Assistant Professor Cheemeng Tan, who led the work. The are built from liposomes, or bubbles with a cell-like lipid membrane, and purified cellular components including proteins, DNA and metabolites.

“We demonstrated that artificial cells can sense, react and interact with bacteria, as well as function as systems that both detect and kill bacteria with little dependence on their environment,” Tan said.

Hierarchical 3D printing of nanoporous gold could ‘revolutionize’ electrochemical reactor design

Posted by in categories: 3D printing, materials

Nanoporous metals are superior catalysts for chemical reactions due to their large surface area and high electrical conductivity, making them perfect candidates for applications such as electrochemical reactors, sensors and actuators.

In a study published today in the journal Science Advances, Lawrence Livermore National Laboratory (LLNL) researchers, along with their counterparts at Harvard University, report on the hierarchical 3D printing of nanoporous gold, a proof of concept that researchers say could revolutionize the design of chemical reactors.

“If you consider traditional machining processes, it’s time consuming and you waste a lot of materials—also, you don’t have the capability to create complex structures,” said LLNL postdoctoral researcher Zhen Qi, a co-author on the paper. “By using 3D printing we can realize macroporous structures with application-specific flow patterns. By creating hierarchical structures, we provide pathways for fast mass transport to take full advantage of the large of nanoporous materials. It’s also a way to save materials, especially precious metals.”

Realize the Promise of Gene-Edited Crops

Posted by in categories: biotech/medical, food, genetics

A far better approach, then, is the middle course. Rather than prejudge the products of biotechnology, regulators should screen new plants and single out those that might need special monitoring or restrictions. In the U.S., the Food and Drug Administration does something similar on a voluntary basis for foods made from plants with engineered proteins. Companies submit data about their new products, and if the FDA decides it has no further questions, they can claim their foods are “generally recognized as safe.”

Europe and the U.S. should avoid an all-or-nothing approach to regulating plants made with Crispr.

Activists urge killer robot ban ‘before it is too late’

Posted by in categories: geopolitics, robotics/AI, treaties

Countries should quickly agree a treaty banning the use of so-called killer robots “before it is too late”, activists said Monday as talks on the issue resumed at the UN.

They say time is running out before weapons are deployed that use lethal force without a human making the final kill-order and have criticised the UN body hosting the talks—the Convention of Certain Conventional Weapons (CCW)—for moving too slowly.

“Killer robots are no longer the stuff of science fiction,” Rasha Abdul Rahim, Amnesty International’s advisor on artificial intelligence and human rights, said in a statement.
