Will Warmer Weather Wipe Out COVID?

What matter mosts, heat or humidity? The conundrum of warm versus cold weather can be untangled a bit if you consider humidity as a cofactor with heat. The short answer is that more aerosolized virus particles are in transit when it is arid and less aerosolized virus particles are in transit when it is humid.Continue reading “Will Warmer Weather Wipe Out COVID?”

COVID Risk Reduction

A systematic review and meta-analysis of how distance, masks, and eye protection reduce virus transmission was published in The Lancet on June 1, 2020. The scope of the review included 172 observational studies across 16 countries and six continents. There are three key findings involving over 25,000 participants in health-care and non-health-care settings. The AbsoluteContinue reading “COVID Risk Reduction”

This IS NOT Your Brain On Drugs!

One of the challenges facing drug makers is the eventuality of human trials. Obviously, there is some danger in that eventuality that requires a great deal of testing prior to that stage of the game. A team of researchers from both China and the USA have developed a way to 3D print cells onto aContinue reading “This IS NOT Your Brain On Drugs!”

Lite Brite Cancer Therapy

Did you know that you can wrap up misbehaving cells with attitude-adjusting nano-sheets and ‘show them the door’? Well, now you do. A team of scientists at the Department of Biomedical Engineering at Texas A&M University have created Molybdenum disulfide (MoS2) nano-sheets that become activated by a thing called Near Infrared Radiation (NIR). Here’s howContinue reading “Lite Brite Cancer Therapy”

Itsy Bitsy Micro Depot

The thought of pulling tape off of your skin is not pleasant. Imagine taping your skin with tape full of needles. Wut? Sounds worse than it is. Let me explain. Introducing the detachable hybrid microneedle depot (d-HMND). The picture above has a little white bar indicating the scale size of 3 millimeters. The itsy bitsyContinue reading “Itsy Bitsy Micro Depot”

Perceptron Shock … the Newest Transformer

Well … not really, but it made you look? A research team at South Ural State University in Chelyabinsk Russia is working a neural network design for making the shock absorbers in your car work better than ever before. There are three ways to do this. Passive (old school) springs or gas pistons that reallyContinue reading “Perceptron Shock … the Newest Transformer”

Hot & Muggy Batteries

You might have noticed that arid environments make it easy to build up static electricity, and you might recall that Ben Franklin pulled some power from a thunderstorm with his kite experiment. Did you know that high humidity and the right metal combination can result in a battery? People have been thinking about this effectContinue reading “Hot & Muggy Batteries”

Antibacterial Laser Tattoos

OK … not really, but yeah sort of. Researchers at Purdue University transform regular copper (Cu) into laser-textured copper (LT-Cu) capable of killing a number of bacterial strains including MRSA in anywhere from 40 to 120 minutes. The short story on this technique is that the laser etches micron (one thousandth of a millimeter) andContinue reading “Antibacterial Laser Tattoos”

I Can’t Get NO INTERaction

So … COVID-19 hits the scene and stuff happens. The plight of Professors forced to move everything online for the indefinite future might go something like this. My apologies to the Rolling Stones for the parody of their most excellent song otherwise known as “(I Can’t Get No) Satisfaction”. I can’t get no INTERaction IContinue reading “I Can’t Get NO INTERaction”
