New study shows 17 years of potential T cell immunity in SARS-infected patients
God has a way of prepping the human body for potentially deadly viruses to somewhat mitigate the amount of death we’d otherwise suffer every year from all sorts of microbiological threats. COVID-19 is not different.
The latest research on T cells, white blood cells produced by the immune system to ward off infections through memory of past pathogens, show that even those patients who never develop antibodies or have lost them over time will retain T cell immunity that remembers to fight off coronaviruses in the future. Moreover, the study provides new evidence for the theory that herd immunity could be achieved at an approximately 20% infection rate for most cities, thanks to T cell cross-immunity from other coronaviruses.
Langen Motorcycles is a vintage British brand from Manchester with a storied history reaching back to … Oh, 2019. Well it certainly looks vintage, in the finest hipster tradition. It’s a new concern started by Christofer “Langen” Ratcliffe, the ex-Chief Design Engineer at CCM Motorcycles, which explains some of the visual similarities between the new Langen 2-Stroke and the CCM Spitfire we first saw in 2017.
The CRISPR-Cas9 gene editing system is an extremely powerful tool, but there are still a few kinks to iron out. One of the main problems is off-target edits, which can have serious consequences. Now, researchers have found a particular mutation of the CRISPR enzyme that’s almost 100 times more precise than the most commonly used one.
As home to a waste-to-energy power plant topped by an artificial ski slope, while featuring running trails and a rooftop bar, the CopenHill facility in Denmark was already a particularly versatile space. Some finishing touches have now been added to the building facade that will add yet another activity to its repertoire, with the routes now complete on what is claimed to be the tallest climbing wall in the world.
The new Maverick Hornet is one of the cutest compact camper trailers you’ll ever see off the beaten path. But don’t let its small size and cube-like dimensions fool you – it’s still a no-nonsense, galvanized-steel backcountry warrior with the most vacant, inhospitable stretches of Australian Outback in its crosshairs. The tiny body that barely overhangs the tire below slides, folds and swings into a comfy base camp complete with trailer-top tent, wraparound awning and outdoor kitchen.
If there are three things we’ve noticed about Australian off-road camper trailers, it’s that they’re insanely well-built, beautifully equipped and incredibly expensive. You can buy a luxury SUV for what a Patriot X3 will cost you. The Maverick Hornet appears as extremely well-built as other Aussie off-road trailers, but it slides in at a much lower price point by relying on a leaner standard equipment package, allowing buyers to build it up with options or equip it themselves over time.
- A Russian oil company called in the army to fight an oil well fire it was unable to control.
- The Russian army sent a Rapira anti-tank gun and crew to shell the wellhead.
- An anti-aircraft gun isn’t the biggest weapon used to stop a fire. Think much bigger. Much, much bigger.
Russian troops called in to battle a Siberian oil well fire got the job done with an unusual firefighting tool: an anti-tank gun. The army troops were requested after the owners of an oil wellhead that had caught fire were unable to put out the blaze. The gun, designed to kill NATO tanks, successfully extinguished the fire.
All cells in the human body have a shelf-life, but those of the cancerous variety use some cunning trickery to outlive their expiry dates and continue spreading throughout the body. Scientists at the University of Tokyo have developed a synthetic version of a fungal compound that could help swing things back in our favor, by reactivating a missing gene that would normally drive these sinister cells to self-destruction.
