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.

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).

Washing hands and Halloween candy can reduce COVID-19 exposure risk

New research shows that COVID-19 exposure risk from contaminated candy could be successfully mitigated both by washing hands and washing candy using a simple at-home method. A team of researchers published this work today in mSystems, an open-access journal of the American Society for Microbiology.

Researchers identify distinct link between autism and brain cell abnormalities

Johns Hopkins Medicine researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges platonic (non-sexual) feelings of love and sociability.

MD65 IgG-YTE shows powerful post-exposure neutralization of SARS-CoV-2

A recent study published in the preprint server bioRxiv in October 2020 describes a reliable animal model to demonstrate the powerful capacity of human neutralizing mAbs directed against SARS-CoV-2 to prevent viral binding the host cell receptor and thus block infection. This indicates the lifesaving value of mAbs in severe COVID-19.

Tumor suppressor gene represses 'jumping genes'

About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or "jumping genes," from hopping around the human genome.
