Ruby Princess sparks Covid concerns after a dozen passengers reportedly test positive in US

Posted by in category: biotech/medical

Princess Cruises’ ship was at centre of 2020 outbreak in Sydney which resulted in over 900 cases and 28 deaths.


The Ruby Princess cruise ship sparked concerns about a Covid-19 outbreak in San Francisco after a dozen passengers were reported to test positive.

It is nearly two years since a Covid outbreak when the ship docked in Sydney resulting in over 900 infections and 28 deaths.

Giant dying star explodes as scientists watch in real time — a first for astronomy

Posted by in categories: cosmology, materials

Astronomers were first alerted to the star’s unusual activity 130 days before it went supernova. Bright radiation was detected in the summer of 2020 by the University of Hawaiʻi Institute for Astronomy Pan-STARRS telescope on Maui’s Haleakalā.

Then, in the fall of that year, the researchers witnessed a supernova in the same spot.

They observed it using the W.M. Keck Observatory’s Low Resolution Imaging Spectrometer on Maunakea, Hawai’i, and named the supernova 2020tlf. Their observations revealed that there was material around the star when it exploded — the bright gas that the star violently kicked away from itself over the summer.

Novel memory technology based on compound semiconductors

Posted by in categories: computing, electronics

A pioneering type of patented computer memory known as ULTRARAM has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture.

ULTRARAM is a novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it utilizes the unique properties of compound semiconductors, commonly used in such as LEDS, laser diodes and infrared detectors, but not in , which is the preserve of silicon.

Initially patented in the US, further patents on the technology are currently being progressed in key technology markets around the world.

‘Ocean battery’ targets renewable energy dilemma

Posted by in categories: energy, sustainability

A wind turbine sitting idle on a calm day or spinning swiftly when power demand is already met poses a problem for renewables, and is one researchers think can be tackled under the sea.

In one vision, could use seawater to essentially store until it’s needed, helping wean humanity off fossil fuels.

“We came up with a solution that we call the battery,” Frits Bliek, CEO of Dutch startup Ocean Grazer told AFP while showing off the at the CES tech fair in Las Vegas.

They say that good things take time, but the James Webb Space Telescope is well on its way to exploring the universe!

Posted by in categories: energy, space

🚀

In the two weeks since its launch on December 25 at 7:20 am ET, Webb has successfully completed many milestones:

✨ Webb released and deployed its solar array, which means the telescope went off battery power and began to use its own generated power.
✨ Webb has had two planned mid-course correction burns. Webb was launched on a direct path to an orbit around the second Lagrange Point (L2), but its trajectory required correction maneuvers to get there.
✨ The 5-layer sunshield has been fully deployed and tensioned. Did we mention it is the size of a tennis court? 🤯
✨ Webb’s secondary mirror, which plays an important role in reflecting light collected by the primary mirror into the telescope’s instruments, has been deployed.
