Future Of Driving: Testing Electric-Vehicles In Four Countries (WSJ Video)
Dozens of new electric-vehicle models are expected to arrive at dealerships in the next few years. We followed eight Wall Street Journal reporters in four countries to see if they, and the world, are ready to make the switch.
Exercise: Older Adults With Higher Muscle Mass Reduce Cardiovascular Disease By Over 80% (Study)
From a Journal of Epidemiology & Community Health online release:
The 10 year CVD (cardiovascular disease) incidence increased significantly across the baseline SMI (skeletal muscle mass index) tertiles (p<0.001). Baseline SMM (Skeletal muscle mass) showed a significant inverse association with the 10 year CVD incidence (HR 0.06, 95% CI 0.005 to 0.78), even after adjusting for various confounders. Additionally, participants in the highest SMM tertile had 81% (95% CI 0.04 to 0.85) lower risk for a CVD event as compared with those in the lowest SMM tertile.
Background Skeletal muscle mass (SMM) is inversely associated with cardiometabolic health and the ageing process. The aim of the present work was to evaluate the relation between SMM and 10 year cardiovascular disease (CVD) incidence, among CVD-free adults 45+ years old.
Methods ATTICA is a prospective, population-based study that recruited 3042 adults without pre-existing CVD from the Greek general population (Caucasians; age ≥18 years; 1514 men). The 10 year study follow-up (2011–2012) captured the fatal/non-fatal CVD incidence in 2020 participants (50% men). The working sample consisted of 1019 participants, 45+ years old (men: n=534; women: n=485). A skeletal muscle mass index (SMI) was created to reflect SMM, using appendicular skeletal muscle mass (ASM) standardised by body mass index (BMI). ASM and SMI were calculated with specific indirect population formulas.
The global population is ageing at an unprecedented speed, especially in Europe. As a concept, ageing is considered a continuous process starting from birth and is accompanied by various physiological changes and a number of comorbidities1 2 that affect health and quality of life.3 4 Skeletal muscle mass (SMM)4 alterations are among these physiological changes.
SMM tissue decline, as a part of these physiological changes, starts in middle age (or even earlier, in the 30s) and progresses in more advanced age.5 It has been shown that SMM declines with a rate of more than 3% per decade starting from the age of 30+.6 Half of the human body’s mass is actually SMM and it has an active role in numerous metabolic pathways.5 7 SMM decline is related, among others, to various disability patterns, poor mental health and increased mortality.5 7 8 In addition, well documented studies have shown that SMM alterations are related to cardiovascular health,9 10 even different muscle morphology.11 Recently, Srikanthan et al 12 reported the importance of muscle tissue in relation to cardiovascular disease (CVD) and total mortality in stable CVD patients.
Weight Loss: Medical Review Of “Keto, Atkins, and Pritikin Diets” (JAMA)
There are many named diets that receive a great deal of attention. But what are they and do they work? David Heber, MD, PhD, from the UCLA Center for Human Nutrition explains these diets.
Studies: Heart Surgery Patients Can Be Safely Discharged In 3 Days
From a News-Medical.net online release:
“Patients can go home after a shorter length of stay in the hospital without increased risk of complications and rehospitalizations,” said Dr. Malaisrie. “Because we found no detrimental effect of accelerated discharge, both patients and physicians should not be averse to discharging patients when medically ready.”
Dr. Malaisrie anticipates that the Northwestern Medicine cardiac ERAS program will result in faster recoveries, reduced complications, decreased time in the hospital, lower costs, and improved patient/family satisfaction. In the future, the researchers plan to closely examine both traditional clinical endpoints and patient-reported outcomes from the program.
“Expectations for recovery after cardiac surgery are being reset in the current era,” he said. “What does this mean for patients? It means that prolonged or taxing recovery is no longer required. Patients should know that recovery from heart surgery is not only quicker, but also better with ERAS programs.”

Interviews: 72-Year Old Artist James Wrayge
Excerpts from a NextAvenue.org online article interview:
“I don’t like the word ‘evolve,’” he says. “Art means the same thing today as it always has. Styles change, but art doesn’t.”
Hesitant to put too defining a label on his work, Wrayge claims his paintings have “a landscape feel.” He doesn’t consider them to be abstract. “That’s a word invented by the press, not by painters,” he says. “What I prefer to say [about my paintings] is that they are a visual manifestation of my values.”
In James Wrayge’s quiet studio on an early winter afternoon, there is a tangible sense of purpose. Wrayge’s paintings line the walls along the portion of the space he shares with another artist at the Northrup King Building in Minneapolis. There are also some paintings on the floor propped up against the same walls. And there is one — in progress — set on an easel in the corner.
History & Literature: “Homer and the Epics”
The bard and the visual artists he inspired.
Phoebe C. Segal, Mary Bryce Comstock Curator of Greek and Roman Art
Homer is the legendary author of the Iliad and the Odyssey, two epic poems that are the central works of ancient Greek literature. The Iliad is set during the Trojan War, the ten-year siege of the city of Troy by a coalition of Greek kingdoms. It focuses on a quarrel between King Agamemnon and the warrior Achilles lasting a few weeks during the last year of the war. The Odyssey focuses on the ten-year journey home of Odysseus, king of Ithaca, after the fall of Troy. Many accounts of Homer’s life circulated in classical antiquity, the most widespread being that he was a blind bard from Ionia, a region of central coastal Anatolia in present-day Turkey. Modern scholars consider these accounts legendary.

Cars: “1961 Dodge Dart Phoenix Convertible”
For the 1961 model year, the Dart continued as the smallest full-size Dodge. It retained the 118 in (2,997 mm) wheelbase, and was restyled to emulate the larger Polara. The same three trim levels were available: the premium Phoenix, mid-range Pioneer, and base Seneca. Once again, wagons shared the Polara’s 122 in/310 cm wheelbase; they also shared the Polara’s unique side-mounted taillights.
The Dodge Dart is a line of automobiles marketed by Dodge from the 1959 to 1976 model years in North America, with production extended to later years in various other markets.
The Dart name originally appeared on a 1956 Chrysler show car featuring a streamlined body designed by the Italian coachbuilder Carrozzeria Ghia that was later modified and renamed the Dart Diablo. The production Dart was introduced as a lower-priced, full-size Dodge in 1960 and 1961, became a mid-size car for 1962, and then was a compact from 1963 to 1976.
