Tibetan people have multiple adaptations for life at high altitudes

Study of 27 Tibetan genomes finds adaptations and relationships to Han Chinese, Denisovans

Summary:The Tibetan people have inherited variants of five different genes that help them live at high altitudes, with one gene originating in the extinct human subspecies, the Denisovans.

Resource availability drives person-to-person variations in microbes living in the body

Ecological model reveals relationships between resource availability and microbe species abundance

Source:PLOS

Summary:The collection of microbial species found in the human body varies from person to person, and new research suggests that a significant part of this variation can be explained by variability in shared resources available to the microbes.

Summary:Parkinson’s disease may start in the gut and spread to the brain via the vagus nerve, according to a study. The vagus nerve extends from the brainstem to the abdomen and controls unconscious body processes like heart rate and food digestion.

Environmental enrichment triggers mouse wound repair response

Source:Cell Press

Summary:Living in a stimulating environment has a wide range of health benefits in humans and has even been shown to fight cancer in mice, but the underlying mechanisms have been unclear. A study now reveals that cognitive stimulation, social interactions, and physical activity increase lifespan in mice with colon cancer by triggering the body’s wound repair response.

Low-sodium diet might not lower blood pressure

Findings from large, 16-year study contradict sodium limits in Dietary Guidelines for Americans

Source:Experimental Biology 2017

Summary:A new study that followed more than 2,600 men and women for 16 years found that consuming less sodium wasn’t associated with lower blood pressure. The study adds to growing evidence that current recommendations for limiting sodium intake may be misguided.

Estrogen alters memory circuit function in women with gene variant

Hormone-gene interaction may underlie sex/individual differences in mental disorders

Source:NIH/National Institute of Mental Health

Summary:Fluctuations in estrogen triggered atypical functioning in a key brain memory circuit in women with a common version of a gene. Brain scans revealed altered circuit activity linked to changes in the sex hormone in women with the gene variant while they performed a working memory task. The findings may help to explain individual differences in risk for, onset, severity, and course of mental disorders, which are often marked by working memory deficits.

New genetic variants associated with extreme old age

Source:Boston University Medical Center

Summary:The search for the genetic determinants of extreme longevity has been challenging, with the prevalence of centenarians (people older than 100) just one per 5,000 population in developed nations. But a recently published study that combines four studies of extreme longevity, has identified new rare variants in chromosomes 4 and 7 associated with extreme survival and with reduced risks for cardiovascular and Alzheimer’s disease.

The 13 Weirdest Religious Sex Beliefs

Rachel Stewart

There are a lot of relatively sound religious rules to live by, according to some old books, but when it comes to sex the rules aren’t only endless, they’re ridiculous and sometimes completely absurd. From curbing sexual impulses for your own spouse, to God-sanctioned one-night stands, to an afterlife of virgin-filled orgies, here are the top thirteen weirdest religious sex rules and beliefs courtesy of the biggest religions on Earth. Believe it or not but nothing about dry humping is on this list.

Is soda bad for your brain? (And is diet soda worse?)

Both sugary, diet drinks correlated with accelerated brain aging

Source:Boston University

Summary:Excess sugar — especially the fructose in sugary drinks — might damage your brain, new research suggests. Researchers found that people who drink sugary beverages frequently are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller hippocampus. A follow-up study found that people who drank diet soda daily were almost three times as likely to develop stroke and dementia when compared to those who did not.
