New algorithm mimics electrosensing in fish

Credit: Unsplash/CC0 Public Domain While humans may struggle to navigate a murky, turbid underwater environment, weakly electric fish can do so with ease. These aquatic animals are specially adapted to traverse obscured waters without relying on vision; instead, they sense their environment via electric fields. Now, researchers are attempting to adapt these electrosensing techniques to improve underwater robotics. Scientists have spent years studying how weakly electric fish—including the knife fish and elephantnose fish—utilize electricity for navigation. These fish have specialized…

CES 2021: Advanced Devices, Advanced Designs

One of the bright notes of the new year and decade is the annual Consumer Electronics Show (CES), currently going on in virtual form due to the current circumstances. One benefit of an electronic event, however, is the ability to actually navigate without shouldering your way through groups of people moving frustratingly slow. The difference in technology between the first CES I attended in 1985 and the current event is as striking as watching a movie from the period and…

What does a rock climbing belay device have in common with a subsea cable installation vessel?

A cable exhibiting torsion (above) and writhing (below). Credit: SINTEF ,What does a rock climbing belay device have in common with a subsea cable installation vessel? The answer is that both can cause torsion, meaning the climbing rope or cable will start to twist. Up until now, no-one could explain why this happened. However, two enthusiastic researchers, who happen to be rock climbers, made it their business to solve the mystery. The construction of offshore wind and solar farms requires…

Simulation for Observability, reliAbility, and secuRity

Serving more than approximately 25 million Internet properties is not an easy thing, and neither is serving 20 million requests per second on average. At Cloudflare, we achieve this by running a homogeneous edge environment: almost every Cloudflare server runs all Cloudflare products. Figure 1. Typical Cloudflare service model: when an end-user (a browser/mobile/etc) visits an origin (a Cloudflare customer), traffic is routed via the Internet to the Cloudflare edge network, and Cloudflare communicates with the origin servers from that…

Combination treatment for methamphetamine use disorder shows promise — ScienceDaily

A combination of two medications, injectable naltrexone and oral bupropion, was safe and effective in treating adults with moderate or severe methamphetamine use disorder in a double-blind, placebo-controlled Phase III clinical trial. The findings suggest this combination therapy may be a promising addition to current approaches to treatment, such as cognitive behavioral therapy and contingency management interventions, for a very serious condition that remains difficult to treat and overcome. The research, published today in The New England Journal of Medicine,…
