Water suppresses vasopressin, a hormone linked to fructose-induced obesity and diabetes, according to a new study published in the journal JCI Insight. Andres-Hernando et al. suggest that increased water intake may be a beneficial way to both prevent or treat metabolic syndrome.

Al-Shaar et al. found that greater intakes of total, unprocessed, and processed red meat were each associated with a higher risk of coronary heart disease. Compared with total, unprocessed, or processed red meat, other dietary components such as soy, nuts, and legumes were associated with a lower risk of coronary heart disease. These associations were stronger among older men. These findings are consistent with the effects of these foods on low density lipoprotein cholesterol levels and support a health benefit of limiting red meat consumption and replacement with plant protein sources; this would also have important environmental benefits. The team also found that substituting whole grains or dairy products for total red meat and substituting eggs for processed red meat were also associated with a lower coronary heart disease risk.

Spaceflight is known to impose changes on human physiology with unknown molecular etiologies. To reveal these causes, da Silveira et al. used a multi-omics, systems biology analytical approach using biomedical profiles from 59 astronauts and data from NASA’s GeneLab derived from hundreds of samples flown in space to determine transcriptomic, proteomic, metabolomic, and epigenetic responses to spaceflight.

Immunization with ChAd-SARS-CoV-2-S induces both neutralizing antibody and antigen-specific CD8+ T cell responses. While a single intramuscular immunization of ChAd-SARS-CoV-2-S confers protection against SARS-CoV-2 infection and inflammation in the lungs, intranasal delivery of the vaccine induces mucosal immunity, provides superior protection, and possibly promotes sterilizing immunity, at least in mice that transiently or stably express the hACE2 receptor.
