Early warning signals could help monitor disease outbreaks

New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy makers improve the accuracy of their decisions and allow timely interventions if needed. from Top Health News -- ScienceDaily https://ift.tt/3DvxDk4 via IFTTT

Delta-like SARS-CoV-2 variants are most likely to increase pandemic severity

Mathematical model indicates SARS-CoV-2 variants that combine enhanced transmissibility with the ability to escape immunity cause more infections than variants with either trait alone. Understanding which type of variants are most likely to increase infections and pandemic severity could help researchers and public health officials interpret the significance of novel and existing variants and design tailored public health responses for various scenarios based on a variant's characteristics. In the case of Delta-like variants, vaccination is predicted to be highly beneficial because vaccinations would prevent a greater number of cases that a more transmissible virus would potentially cause, and because the milder nature of breakthrough infections should substantially reduce overall mortality.

Creativity and community: How modern humans overcame the Neanderthals

A new study is the first-ever to identify the genes for creativity in Homo sapiens that distinguish modern humans from chimpanzees and Neanderthals. The research identified 267 genes that are found only in modern humans and likely play an important role in the evolution of the behavioral characteristics that set apart Homo sapiens, including creativity, self-awareness, cooperativeness, and healthy longevity. from Top Health News -- ScienceDaily https://ift.tt/3tIfDio via IFTTT

Certain CBD oils no better than pure CBD at inhibiting certain cancer cell lines

Cannabidiol (CBD) oils are equally or less effective at inhibiting the growth of certain cancer cells compared to pure CBD, according to researchers. The results of their recent study indicate that future research into the clinical applications of cannabinoids should include an analysis of whether the pure cannabinoid compound or intact plant material is more effective at achieving the therapeutic effect. from Top Health News -- ScienceDaily https://ift.tt/3faN9r3 via IFTTT

Could this plaque identifying toothpaste prevent a heart attack or stroke?

For decades, researchers have suggested a link between oral health and inflammatory diseases affecting the entire body -- in particular, heart attacks and strokes. Results of a randomized pilot trial of Plaque HD®, the first toothpaste that identifies plaque so that it can be removed with directed brushing, showed that it produced a statistically significant reduction in C-reactive protein, a sensitive marker for future risks of heart attacks and strokes, among those with elevations at baseline. from Top Health News -- ScienceDaily https://ift.tt/2SVa0NI via IFTTT
