“They used several strategies to stimulate neurogenesis, including voluntary exercise, targeted genetic techniques, and drug-based interventions designed to promote the growth and integration of new neurons.”

“Microplastics may be more than environmental pollutants—they could contribute to the rise of drug-resistant bacteria. These tiny plastic fragments persist in wastewater, providing surfaces where bacteria congregate, form biofilms, and exchange genetic material that enhances antibiotic resistance.”

“SARS-CoV2 exploits ACE2 to gain entry into cells by binding to a cell's ACE2 receptor and injecting its genetic material into the cytosol, where it can replicate. The study involved 68 patients (48 males, 20 females) who had been diagnosed with COVID-19.”

“In addition, both groups exhibited higher numbers of bacteria that break down the mucus layer of the gut (specifically, Akkermansia muciniphila and Bacteroides fragilis), contributing to mucus layer destruction, increasing gut permeability.”

“They also manipulated serotonin levels using genetic tools and monitored the resulting changes in spine density and synaptic function, providing insights into how serotonin shapes neural connectivity during critical developmental periods.”

“Premature ovarian insufficiency – a condition in which the ovaries fail earlier than usual – affects more than 3.5 percent of females worldwide, often due to genetics, autoimmune disorders, or exposure to certain drugs, such as those used in chemotherapy.”

“To address this problem, this study involved 11 pairs of monozygotic (identical) twins whose self-reported sleep patterns differed by at least 60 minutes per night. The authors of the study monitored the participants' sleep and analyzed their gene expression profiles.”

“Optogenetics is a research technique that allows scientists to switch a neuron's activity on or off using light and genetic engineering. They found that older mice had nearly 40 percent fewer hypocretin-producing neurons than younger mice.”

In addition, a mouse model of Werner syndrome – a genetic disorder characterized by premature aging – demonstrated that vitamin C supplementation extended the mean lifespan of the mice and corrected many of the age-related metabolic diseases characterized as metabolic syndrome.

“It plays key roles in the maintenance of blood pressure. SARS-CoV-2, the virus that causes COVID-19, exploits ACE2 to gain entry into cells by binding to a cell's ACE2 receptor and injecting its genetic material into the cytosol, where it can replicate.”
