I recently reported the troubling surge in laughing gas recreational use highlighting the damage that this nitrous oxide gas can do to your mouth and throat as it cools. This rising use of the drug is also killing more of us each year. I am sad to report that 1240 Americans lost their live sto nitrous oxide poisoning between the years 2010 and 2023.

This widely-used medicinal gas safely helps to smooth the induction of general anesthesia in the operation room. In the party room, though, its careless inhalation from pressurized canisters that serve as whipped cream chargers leads to oxygen deprivation, neurological damage, and death.

Don’t let that happen to your or your children. Educate, educate, educate.

What’s the trick? A small modification in your walking gait could delay any need for knee replacement surgery for years. So say University of Utah bioengineers and musculoskeletal researchers after studying a select group of 68 patients with knee arthritis in a year-long placebo-controlled trial.

Their Lancet Rheumotology study revealed that a slight change in the foot angle while walking reduced both the pain and destructive changes of osteoarthritis as effectively as pain and anti-inflammatory medications. The necessary change in foot angle varied for each individual: for some, turning the toes slightly inward did the trick, while for others, turning outward worked better.

The study participants trained with motion-capture and biofeedback. They then practiced at home until their slightly modified gait felt natural. Remarkably, they stuck with the adjustment for the duration of the study.

The most exciting findings: At the study’s conclusion, the MRI scans of those who modified their gaits revealed less cartilage damage than controls. Their pain relief mirrored that achievable with over-the-counter painkillers like ibuprofen and was nearly as good as even stronger agents.

Gold nanoparticles, coated with specific antibodies to viruses, bacteria, or virtually any disease-causing agent, now form the basis of a diagnostic system 100,000 times more sensitive than current technologies and capable of delivering a result in about 15 minutes. Molecular bioengineers at Arizona State University have developed the reagents and the detection device they’ve named the NasRED, which stands for Nanoparticle-Supported Rapid Electronic Detection.

For example, when exposed to say antigens from CoVid viruses, the CoVid-antibody coated gold nanoparticles clump together and capably reflect light in the NasRed detector. This one-drop blood test can rapidly and precisely detect COVID-19, influenza, HIV, Ebola, and/or Lyme with unprecedented precision. Each test costs about two dollars, a fraction of the price of current lab methods. The detection device is small and portable permitting its use in rural hospital and clinics.

Work is already underway to shrink the test prep and detection devices even further, raising the possibility of a do-it-yourself home test with better than lab-quality accuracy……someday soon.
