March 25, 2021 -- The new coronavirus variants are not just problems for humans.
New research shows they can also infect animals, and for the first time, variants have been able to infect mice, a development that may complicate efforts to rein in the global spread of the virus.
In addition, two new studies have implications for pets. Veterinarians in Texas and the United Kingdom have documented infections of B.1.1.7 — the fast-spreading variant first found in the U.K. — in dogs and cats. The animals in the U.K. study also had heart damage, but it's unclear if the damage was caused by the virus or was already there and was found as a result of their infections.

Paraytec wins at “The Oscars of Invention”
The R&D 100 Awards, “The Oscars of Invention” provide companies with a mark of excellence which is recognised by industry, government and academia as proof that the product is one of the most innovative ideas of the year. In it’s 45th year, the R&D 100 Awards have been providing companies, like Paraytec, with a platform from which to launch into the international marketplace.

Maybe also because this product is unique, it will be the first reusable device that is also market leading in speed and quite possibly accuracy. This is the device which can open up society and quite possibly reignite the Governments moonshot ambitions. IMO
All I see is the government spending billions in one off testing devices. We can save 100’s and 100’s of millions and perhaps even billions using a device that is reusable rather than these throw away one offs.
School's Covid test trial stops pupils having to isolate
Now the government is inviting schools and colleges to sign up for a clinically-overseen trial of daily contact testing - and a number of schools have already joined an early phase of the trial.
It means that instead of having to learn from home, students who are close contacts can remain in school as long as they agree to be tested for Covid daily for seven consecutive school days.
Westhoughton headteacher Patrick Ottley-O'Connor and school business manager Ann Butler, the trial lead, said the team jumped at the chance to join the early phase and said pupils are already seeing the benefits.
"However, owing to this new pilot, our son has been able to remain in school. After a turbulent 12 months, I think that this trial is a positive step forward to enable the children to remain in school, not only for their learning, but also for their social and mental well-being.”
The daily testing was something the government initially said it would bring in to secondaries and colleges from January to help prevent disruption, but concerns over the accuracy of lateral flow test results prevented that happening.
A government spokesperson said: “Schools and colleges are being invited to participate in a clinically-overseen trial of daily contact testing.

Cheers. I thought it was a fair and question and not one I had considered. For me, seeing that deal highlights the desire for this new tech. The products are for home testing and not the market we are aiming for. However, if a throw away cheap device can achieve that, than I expect our reusable device to be far more powerful.
Ellume wins $232M deal for fluorescence-based Covid-19 home test kits
03 Feb 2021
Ellume, a Brisbane, Australia, company that has developed an optics-based rapid antigen test for Covid-19 suitable for home use, has won a $232 million contract with US authorities that should lead to a huge increase in production.
Said to be the the first rapid self-test for Covid-19 detection authorized by the US Food & Drug Administration (FDA) for both asymptomatic and symptomatic use without a prescription, Ellume’s device relies on fluorescent nanoparticles and simple optoelectronics
Aside from the Covid-19 test kits, Ellume is working on rapid test kits for diagnosing both tuberculosis and influenza, and previously agreed a partnership with pharmaceuticals giant GlaxoSmithKline

Photonics21: EU needs to invest more in photonics now to fight future infectious diseases and pandemics
Strong investment in photonics will help us fight infectious diseases that kill an unimaginable number of people and prepare us against future pandemics, says Dr Jürgen Popp of the Leibniz Center for Photonics in Infection Research (LPI) that is currently under construction in Jena.
Light offers promising new solutions to tackle infectious diseases that kill millions of people every year
Urgent action needed from EU and governments to invest in photonics technologies
South Korea invests €2.8 Billion per year, China €1 billion – whereas entire EU investment is €100 million p.a.
Investment in photonics is more crucial now than ever. Fast, clean and precise, photonics can build advanced diagnostics, pervasive monitoring and innovative e-health applications that can detect body signals, symptoms and diseases at very early stages.
To tackle future pandemics, medical and health practitioners will need to be equipped with next-generation specialist tools that provide instantaneous diagnostic information that is inexpensive and easy to deploy and should operate at a point of care to the patient.

U.S. Congress Launches O&P Caucus
First up was Bruce Tromberg, director of the National Institute of Biomedical Imaging and Bio-engineering and head of the Rapid Scaling Up of COVID-19 Diagnostic Testing in the U.S.—graciously abbreviated as the RADx Initiative.
Speaking from a biophotonics point of view, Tromberg explored the impact that optics and photonics technologies have had in advancing cutting-edge methods, discoveries and devices in biology and medicine.
Using coronavirus as a case study, Tromberg said that when the RADx Initiative was funded, he knew that “we had game-changing optics and photonics technologies that were ready to jump from research labs to the marketplace. But these methods needed to be combined with molecular assays and undergo intensive de-risking and validation prior to investment.”
As of today, RADx has invested US$520 million in 27 companies for manufacturing expansion, and that “virtually all of these platforms depend on optics and photonics technologies to reveal the presence of an invisible virus.” According to Tromberg, this shows how biophotonic advances and government–academia–industry partnerships can dramatically change the world.

Optics and photonics enable the fight against COVID-19
Jan 27th, 2021
From the initial sequencing of SARS-CoV-2 and the ultraviolet LEDs used in air filtration to spectroscopy-based diagnostic tests like real-time PCR, optics and photonics are enabling the fight against COVID-19.
” With all of this in mind, there is no doubt that photonics will continue to enable not only the next-generation technologies for this current pandemic, but will play a critical role in combating pathogens for the foreseeable future. “
