Wireless devices go battery-free with new communication technique | UW Today

Wireless devices go battery-free with new communication technique | UW Today | Science | Scoop.it

Using ambient backscatter, these devices can interact with users and communicate with each other without using batteries. They exchange information by reflecting or absorbing pre-existing radio signals

Jonas Kuhn's insight:

Nice. And one day devices will absorb the omnipresent waves and charge their battery from that :)

Opinion: ‘Big science’, big hype, big mistake

We are paying too high a price for 100,000 genomes more, warns Bill Amos
Jonas Kuhn's insight:

He talks about focusing more on a broad diversity of projects instead of fewer and fewer big ones. So true.

Answer (1 of 36): Here are some of the best natural phenomena that occur on Earth.

Gippsland Lakes

The spooky light is created by a chemical reaction called “bioluminescence”, which happens when tiny organisms in the water are disturbed.

How Artificial Chromosomes Could Transform Humanity

How Artificial Chromosomes Could Transform Humanity | Science | Scoop.it
Normally, an extra pair of chromosomes would be considered dangerous. But what if we could design our own? According to biologists, we could create custom-built chromosomes to fix a variety of health problems, and even give us new abilities.

Doyle et al, 2013

Transcription activator-like (TAL) effectors are transcription factors injected into plant cells by pathogenic bacteria of the genus Xanthomonas. They function as virulence factors by activating host genes important for disease, or as avirulence factors by turning on genes that provide resistance. DNA-binding specificity is encoded by polymorphic repeats in each protein that correspond one-to-one with different nucleotides. This code has facilitated target identification and opened new avenues for engineering disease resistance. It has also enabled TAL effector customization for targeted gene control, genome editing, and other applications. This article reviews the structural basis for TAL effector-DNA specificity, the impact of the TAL effector-DNA code on plant pathology and engineered resistance, and recent accomplishments and future challenges in TAL effector-based DNA targeting.
