Wuhan Coronavirus Pandemic — USA

California has the first case that cannot be traced back to a traveler from an area with an outbreak.

“It’s significant because it means that it’s also possible the infection is spreading untraced throughout the local community.”

Photoacoustic imaging, a technique for examining living materials through the use of laser light and ultrasonic sound waves, has many potential applications in medicine because of its ability to show everything from organs to blood vessels to tumors.

Caltech’s Lihong Wang, a pioneer in the field, has developed variants of photoacoustic imaging that can show organs moving in real time, develop three-dimensional (3D) images of internal body parts, and even differentiate cancerous cells from healthy cells.

Wang, Bren Professor of Medical Engineering and Electrical Engineering, has now further advanced photoacoustic imaging technology with what he calls Photoacoustic Topography Through an Ergodic Relay (PATER), which aims to simplify the equipment required for imaging of this type.

Why is there something rather than nothing? We’re finally making enough antimatter to extract an answer – and it might reveal the dark side of the universe too.

Some species of deaf moths can absorb as much as 85 per cent of the incoming sound energy from predatory bats—who use echolocation to detect them. The findings, published in the Journal of the Royal Society Interface today, reveal the moths, who are unable to hear the ultrasonic calls of bats, have evolved this clever defensive strategy to help it survive.

Bats hunt at night using echolocation. The technique, which is also known as biological sonar, first evolved around 65 million years ago and enables bats to search for and find prey putting huge predation pressure on nocturnal insects. One defence that many nocturnal insects evolved is the ability to hear the ultrasonic calls of bats, which allows them to actively evade approaching bats.

Many moth species, however, cannot hear. The team of researchers from the University of Bristol wanted to investigate the alternative defences against bats that some species of deaf moths might have evolved.

The “powerhouse of the cell” is apparently not necessary for animal life.

Scientists from Imperial College London have proposed a new regulatory framework for assessing the impact of AI, called the Human Impact Assessment for Technology (HIAT).

The researchers believe the HIAT could identify the ethical, psychological and social risks of technological progress, which are already being exposed in a growing range of applications, from voter manipulation to algorithmic sentencing.

For now, it’s a simple network. But, it could be an important first step toward smarter and more adaptive prosthetics and brain-computer interfaces — and potentially lay the groundwork for a world where neural implants create real brain networks.

“On one side it sets the basis for a novel scenario that was never encountered during natural evolution, where biological and artificial neurons are linked together and communicate across global networks; laying the foundations for the Internet of Neuro-electronics,” Themis Prodromakis, a nanotechnology researcher and director at the University of Southampton’s Centre for Electronics Frontiers said in a press release.

“On the other hand, it brings new prospects to neuroprosthetic technologies, paving the way towards research into replacing dysfunctional parts of the brain with AI chips.”
