Health: Wear “Cloth Face Mask” In Public To Prevent Spread Of Coronavirus

New research suggests that face masks may offer more protection against coronavirus infection than previously thought. It suggests that coughs and sneezes may be projected much further than scientists had thought possible. The World Health Organisation is considering whether to update its guidance on face masks and the White House may recommend that Americans wear them. Meanwhile in the UK hospitality companies are turning their skills to help those in need. And for the second week in a row, applause has rung out from members of the public showing gratitude to NHS staff and other workers helping to keep the country going. Sophie Raworth presents BBC News at Ten coverage from Science Editor David Shukman and Social Affairs Correspondent Alison Holt.

Obesity Study: “Late Night Snacking” Older Adults – Higher Fat Levels Than Early Eaters On Same Diet

From a PLOS Biology Journal study (Feb 20, 2020):

Snacking Before you sleep Keeps on the Fat PLOS Biology April 2020
Schematic: Late-evening snacking interacts with the circadian rhythm of metabolism to inhibit LO.

The major finding of this study is that the timing of feeding over the day leads to significant differences in the metabolism of an equivalent 24-h nutritional intake. Daily timing of nutrient availability coupled with daily/circadian control of metabolism drives a switch in substrate preference such that the late-evening Snack Session resulted in significantly lower LO compared to the Breakfast Session. 

Developed countries are experiencing an epidemic of obesity that leads to many serious health problems, foremost among which are increasing rates of type 2 diabetes, metabolic syndrome, cardiovascular disease, and cancer. While weight gain and obesity are primarily determined by diet and exercise, there is tremendous interest in the possibility that the daily timing of eating might have a significant impact upon weight management [13]. Many physiological processes display day/night rhythms, including feeding behavior, lipid and carbohydrate metabolism, body temperature, and sleep.

PLOS Biology StudiesThese daily oscillations are controlled by the circadian clock, which is composed of an autoregulatory biochemical mechanism that is expressed in tissues throughout the body and is coordinated by a master pacemaker located in the suprachiasmatic nuclei of the brain (aka the SCN [1,4]). The circadian system globally controls gene expression patterns so that metabolic pathways are differentially regulated over the day, including switching between carbohydrate and lipid catabolism [1,3,59]. Therefore, ingestion of the same food at different times of day could lead to differential metabolic outcomes, e.g., lipid oxidation (LO) versus accumulation; however, whether this is true or not is unclear.

Interviews: 66-Year Old American Author Erik Larson On Writing “The Splendid And The Vile”

Erik Larson, #1 New York Times bestselling author, shares his writing process.

In The Splendid and the Vile, Erik Larson shows, in cinematic detail, how Churchill taught the British people “the art of being fearless.” It is a story of political brinkmanship, but it’s also an intimate domestic drama, set against the backdrop of Churchill’s prime-ministerial country home, Chequers; his wartime retreat, Ditchley, where he and his entourage go when the moon is brightest and the bombing threat is highest; and of course 10 Downing Street in London. 

Erik Larson Books

Drawing on diaries, original archival documents, and once-secret intelligence reports—some released only recently—Larson provides a new lens on London’s darkest year through the day-to-day experience of Churchill and his family: his wife, Clementine; their youngest daughter, Mary, who chafes against her parents’ wartime protectiveness; their son, Randolph, and his beautiful, unhappy wife, Pamela; Pamela’s illicit lover, a dashing American emissary; and the advisers in Churchill’s “Secret Circle,” to whom he turns in the hardest moments.

Erik Larson is the author of eight books, six of which became New York Times bestsellers. His latest books, The Splendid and the Vile: A Saga of Churchill, Family, and Defiance During the Blitz and Dead Wake: The Last Crossing of the Lusitania, both hit no. 1 on the list soon after launch. His saga of the Chicago World’s Fair of 1893, The Devil in the White City, was a finalist for the National Book Award, and won an Edgar Award for fact-crime writing; it lingered on various Times bestseller lists for the better part of a decade.
