pH comes from the term “power of Hydrogen”, or the hydrogen ion concentration present in a given solution. It helps to measure the acidity or alkalinity of a substance.

Study shows iscan method could be effective for rapid COVID-19 testing

A simple COVID-19 test kit combines virus amplification with a CRISPR-Cas system for effective SARS-CoV-2 detection. The kit, called iSCAN, uses reagents that can be locally manufactured.

Researchers study link between gut microbiome and the brain in humans, rodents

Despite extensive support for relationships between the gut microbiome and the brain (the "microbiota-gut-brain axis") in humans and rodents, little is known about these relationships in other animals, leaving questions about this system's generality.

Study shows T cells can prevent Zika infection in mice

Where Aedes mosquitoes fly, Zika virus may not be far behind. Although the explosive 2015–2016 Zika epidemics in the Americas are behind us, Zika may re-emerge, and "in many countries, Zika may be spreading in silence," says Sujan Shresta, Ph.D., a professor at La Jolla Institute for Immunology (LJI).

Data science pathway can provide an introductory experience in AI-ML for radiology residents

A recently developed data science pathway for fourth-year radiology residents will help prepare the next generation of radiologists to lead the way into the era of artificial intelligence and machine learning (AI-ML), according to a special report published in Radiology: Artificial Intelligence.

Green tea and some fruit juices inhibit SARS-CoV-2 in vitro

Green tea, chokeberry juice, and pomegranate juice killed flu and SARS-CoV-2 viruses when incubated with the viruses in vitro. Thus, oral rinsing using these might be effective in preventing COVID-19.

Psilocybin may be effective in patients suffering from major depression

In a small study of adults with major depression, Johns Hopkins Medicine researchers report that two doses of the psychedelic substance psilocybin, given with supportive psychotherapy, produced rapid and large reductions in depressive symptoms, with most participants showing improvement and half of study participants achieving remission through the four-week follow-up.

Swelling may be important for protecting the brain after injury, study reveals

Following a brain-injuring bump or blow to the head, brain cells and blood vessels typically swell. This can lead to a potentially life-threatening increase in pressure inside the skull, and managing swelling is critical for patients with traumatic brain injuries (TBIs).

Study finds new clues for disarming antibiotic-resistant bacteria

A virus can stop bacteria from sharing genes for antibiotic resistance among themselves, Texas A&M AgriLife researchers have discovered. The results hint at new ways to treat infections and describe a new feature of a highly diverse, largely unexplored part of the biosphere.
