Death in a 16oz Bottle

Soft drinks associated with risk of death in population-based study in 10 European countries,
JAMA Internal Medicine, September 3, 2019.

MAIN POINTS

Soda Pop Kills Consumers
"Greater consumption of soft drinks, including both sugar- and artificially sweetened, was associated with increased risk of overall death in a population-based study of nearly 452,000 men and women from 10 European countries. Drinking two or more glasses per day (compared with less than one glass per month) of total soft drinks, sugar-sweetened soft drinks and artificially sweetened soft drinks was associated with higher risk of death from all causes during an average follow-up of 16 years in which 41,693 deaths occurred."

Physical activity at any intensity linked to lower risk of early death,
National Institute for Health Research, August 21, 2019.

MAIN POINTS

Any Work
"clear evidence that higher levels of physical activity - regardless of intensity - are associated with a lower risk of early death in middle aged and older people."

Increasing Death
"...being sedentary, for example sitting, for 9.5 hours or more a day (excluding sleeping time) is associated with an increased risk of death."

Study of Studies
"Data from eight high quality studies...involved 36,383 adults aged at least 40 years (average age 62) were used in the analysis."

Final Test…
"During follow-up, 2,149 (5.9 per cent) participants died. After adjusting for potentially influential factors, the researchers found that any level of physical activity, regardless of intensity, was associated with a substantially lower risk of death."

Microplastics Everywhere

Microplastics in Arctic Snow Suggest Widespread Air Pollution,
American Association for the Advancement of Science, August 12, 2019.

MAIN POINTS

Microplastic Air Pollution
"...high concentrations found in snow samples from disparate regions suggest microplastics - which may contain varnish, rubber, or chemicals used in synthetic fabrics - cause significant air pollution."

Arctic Microplastics
"...used an imaging technique to analyze snow samples collected between 2015 and 2017 from floating ice in the Fram Strait, a passage between Greenland and Svalbard to the Arctic Ocean. (They visited five ice floes by ship-based helicopters or dinghies during three expeditions.)"

HEALTH & FITNESS

What's Really Inside Your Body?

California 1st State to Require Notification of Toxic 'Forever' Chemicals in Water,
Desert Sun, July 31, 2019.

MAIN POINTS

PFAS Reporting
"California's law would mandate that consumers receive information on about 5,000 of them if they're detected."

PFAS
"The PFAS chemicals, which have been widely used in everything from firefighting foam to Teflon pans, rain gear and even some dental floss, have been linked in research to cancers, developmental problems and thyroid and liver disease. They're known as "forever chemicals" because they don't break down in the environment or in human bodies."

SOCAL Contamination
"More than 2.4 million people across Los Angeles, Riverside and Orange Counties may be exposed to the dangerous chemicals, according to estimates by environmental advocates and based on U.S. Environmental Protection Agency data. Major airports, military bases and refineries are all conducting testing or will be, per state requirements. While New Hampshire and New Jersey have imposed limits on two PFAS chemicals..."

Keys to Understanding the Mechanisms of Our Degradation of Ourselves & Our Environment

High levels of Estrogen in the Womb Linked to Autism,
University of Cambridge, July 29, 2019. 

MAIN POINTS

"Scientist have identified a link between exposure to high levels of oestrogen sex hormones in the womb and the likelihood of developing autism."

"...further evidence to support the prenatal sex steroid theory of autism first proposed 20 years ago."

"Today, the same scientists have built on their previous findings by testing the amniotic fluid samples from the same 98 individuals sampled from the Danish Biobank, which has collected amniotic samples from over 100,000 pregnancies, but this time looking at another set of prenatal sex steroid hormones called oestrogens. This is an important next step because some of the hormones previously studied are directly converted into oestrogens."

Antidote for Skunk Spray Found

Fungal Compound Deodorizes Skunk Smell,
American Chemical Society, July 24, 2019.

MAIN POINT

Skunk Unique Defense
"When skunks feel threatened, they spray fluids from their anal glands that contain several nasty-smelling organosulfur compounds. The human nose can detect extremely low concentrations of these substances, making it difficult to completely rid clothing, hair, fur or skin of the stink."

Human Tech Insufficient
"Available "de-skunking" formulas often either don't work well or can irritate the skin and eyes."

Savage Tick-Clone Armies are Sucking Cows to Death; Experts Fear for Humans, ArsTechnica, July 11, 2019.

MAIN POINTS

Deadly Tick Attacks
"Ravenous swarms of cloned ticks have killed a fifth cow in North Carolina by exsanguination—that is, by draining it of blood—the state’s Department of Agriculture and Consumer Services warned this week."

Clone Armies of Death
"...a single well-fed female can spawn up to 2,000 tick clones parthenogenetically—that is, without mating—in a matter of weeks."

Unique Persistence
"...unlike other ticks that tend to feast on a victim for no more than seven days, mobs of H. longicorni can latch on for up to 19 days."

"...the National Veterinary Services Laboratories looked back through their tick samples and discovered a larval H. longicornis was isolated from a white-tailed deer in Tyler County, West Virginia, in 2010, backdating the first case known in the US. Still, researchers don’t know when the tick first arrived and were it came from."

Gut Bacteria that Turns Soreness Into Energy

Performance-Enhancing Bacteria Found in the Microbiomes of Elite Athletes,
Joslin Diabetes Center, June 24, 2019.

MAIN POINTS

Veillonella Gut Bacteria
"New research has identified a type of bacteria found in the microbiomes of elite athletes that contributes to improved capacity for exercise. These bacteria, members of the genus Veillonella, are not found in the guts of sedentary people."

"One of the things that immediately caught our attention was this single organism, Veillonella, that was clearly enriched in abundance immediately after the marathon in the runners."

Veillonella Eats Lactic Acid
"As we dug into the details of Veillonella, what we found was that it is relatively unique in the human microbiome in that it uses lactate or lactic acid as its sole carbon source."

"Lactic acid is produced by the muscles during strenuous exercise. The Veillonella bacteria are able to use this exercise by-product as their main food source."

Coffee Reduces Death

Research suggests coffee consumption associated with reduced risk of death,
Institute for Scientific Information on Coffee, July 31, 2018.

Less Death for Coffee Drinkers
“...presented unpublished original research studying a cohort of almost 20,000 participants over an average of ten years...research suggests that coffee consumption at intakes of 3-6 cups of coffee a day reduces all-cause mortality. Within this cohort, there was a 22% lower risk of all-cause mortality for each two additional cups of coffee per day.”

Not Just the Caffeine
“...suggested that caffeine alone was unlikely to explain the effect on mortality, mentioning a potential role for polyphenols found in coffee, which may have antioxidant and anti-inflammatory effects.”

Less Death
“Meta-analyses have suggested that coffee consumption versus no coffee consumption is associated with an up to 17% risk reduction of all-cause mortality.”

Avalanche Victims: When can Rewarming Lead to Survival?
Eurac Research, May 28, 2019.

MAIN POINTS

"This study analysed the data relating to 103 avalanche victims admitted with cardiac arrest to seven major hospitals in Europe, between 1995 and 2016."

Two Types of Avalanche Deaths
"Of the 103 victims, 61 were rewarmed, but only 10 per cent survived; in the other cases it was not the hypothermia that caused the cardiac arrest, but suffocation during the avalanche or trauma."

The Survival Standard
Frozen or Suffocation Heart Stoppage?
"...hospitals require accurate guidelines based on significant evidence to justify extracorporeal rewarming using the heart-lung machine."

Survival Standards Found
"The factors that have emerged as decisive in this study are the core temperature and the concentration of serum potassium, the latter is related to cell degeneration. Using both these parameters, doctors can assess which patients have the potential to survive and which do not."

Running Young

Training for First-Time Marathon 'Reverses' Aging of Blood Vessels,
European Society of Cardiology, May 3, 2019.

MAIN POINTS

Running Young
"Training for and completing a first-time marathon "reverses" ageing of major blood vessels, according to research presented today..."

Four Years
"Novice runners who trained for six months and completed their first marathon had a four-year reduction in arterial age and a 4 mmHg drop in systolic blood pressure. This is comparable to the effect of medication, and if maintained translates to approximately 10% lower risk of stroke over a lifetime."

Potential
"Compared to their peers, lifelong athletes have biologically younger blood vessels. This study investigated whether training for a marathon could modify aortic stiffness even in novice runners."
