How Do Wildfires Affect Ocean Ecosystems?

One December day in 2017, I lined up with friends at a Santa Barbara theater under a “Holiday Concert” marquee in a wintry scene replete with whirling white flakes. But there would be no music, only coughing and distant sirens. It was wildfire ash falling onto the holly wreaths that day, and we were in line for concert cancellation refunds.

Is It Necessary to Take L-arginine Supplements?

A cornucopia of confusion surrounds the benefits of taking L-arginine supplements. Also called just "arginine," there's some evidence that this amino acid may lower blood pressure and improve heart health, but there's little agreement among experts about safe dosage or its interaction with alcohol.

Covid complications take the life of pioneering Black scientist who spent her life fighting viral infections

Evelyn Nicol (1930–2020), a world-renowned immunology expert and one of few Black women scientists to ever be awarded a patent for a new medical treatment, died of complications from Covid-19 in May, just a week before her 90th birthday. In 1976, Nicol became the rare Black American to be awarded a patent for a scientific product, and reportedly the first for a patent in the field of Molecular Biology. Link to Story

What Makes Those Eyebrows Twitch?

Uncontrollable eyebrow twitching is not only random, but awkward. Not fun on a first date or a job interview. It's often caused by stress, lack of sleep or even excess caffeine, but low magnesium levels may also be a trigger. Whether it's around the eyebrow, lips, forehead or eyelids, "in adults, a facial spasm rarely indicates an underlying medical condition," says Ali Samii, MD, a neurologist at University of Washington Medicine who specializes in movement disorders and spasticity.

Microfluidics and Approval Bottlenecks in a Pandemic

Minimizing harm to patients from inadequately-tested new pharmaceuticals — and the bankroll-boggling process of adequate testing — are grabbing pandemic headlines. “The pharmaceutical industry needs new ways of doing things” is one example. Microfluidics advances have hovered on the horizon as a “new way” for some time. Link to Story

Not All In This Together

In the U.S. pandemic’s early months, African-American patients’ infection and death rates soared. “How many people will die this summer, before Election Day? What proportion of the deaths will be among African-Americans, Latinos, other people of color? This is getting awfully close to genocide by default. Link to Story

There Are ‘Not Enough Truck Drivers’ To Match COVID-19 Demand

Sanitizer and toilet paper comprise but a small portion of what truck drivers deliver. They also move COVID-19 tests, disinfectant cleaning fluid, critical hospital supplies, surgical masks, plastic gloves, food, diapers, cellphones, computers and more. The ongoing crisis has fueled temporary changes in safety regulations. Link to Story

Can You Lower CRP Levels?

You may never have noticed a C-reactive protein (CRP) level on your blood test results. But it's an important marker of inflammation — and one that can help predict your risk for a heart attack. When illness or injury strikes, CRP levels in the bloodstream rise as your immune system goes into action. Link to Story

Generating Electricity by Making Batteries from Human Microbes? Microfluidics Hold the Key

Microfluidics advances appear in sometimes surprising ways. One of the most intriguing is their emerging role in microbiome research. A new study shows how some bacteria in the microbiome, inside the human intestine, generate electricity outside of their own cell walls. The potential for microfluidics’ role in this research is significant, considering that the electricity generated in gut bacteria might be harnessed on a large scale — for example, at a bacteria-laden waste processing facility.

Wearable Technology Innovations are Fueled by Microfluidics Research

The density of metabolites in sweat — along with its ease of collection from skin pores — make it a useful biofluidic candidate for analysis. One recent study looked at how microchannels and micro reservoirs, pre-filled with fluorescent probes that react to target analytes in sweat, can perform quantitative analysis. Link to Story

What you should eat and drink to get over the flu, according to doctors

When you're sick with the flu, it's no fun trying to figure out what to eat and drink. That's why we've put together a list of doctor-recommended foods and fluids to help. Link to Story

ROOTS OF HEALING | Ojai Herbal Symposium will cover pros, cons and research on herbs as medicine

Do medicinal herbs curb illness as well as pharmaceutical drugs? What are the biological reasons that naturally-growing plants can alleviate symptoms? Answers are on the way.
