Environmental Estrogens Penetrate Placenta

Babies Burdened by Environmental Estrogens in Mothers' Wombs,
Swiss Federal Laboratories for Materials Science and Technology (EMPA), October 10, 2019.

MAIN POINTS

Danger: Natural Sources
"Xenoestrogens are absorbed through the environment, especially through food. As oestrogen-like substances, they can have a profound effect on the body's hormonal balance."

Environmental Estrogen Penetrates Placenta
"The placental barrier offers the unborn child a certain protection against bacteria, viruses and some substances such as some medications or environmental toxins absorbed by the body. But zearalenone migrates through the placenta, as we have now been able to show for the first time..."

Our goal here is to provide the best information how to deal with internal and external threats to your health. But why?

 

FIELD GRADE
Our greater goal is to attain "Field Conditioning." Field Conditioning is an advanced state of fitness where we are capable of moving and operating effectively across great distances over all types of terrain, at high or low altitude, in hot, cold, wet, or dry conditions over extended time spans, under all seasonal conditions, while carrying the weight required to withstand these environmental conditions, feed ourselves well, and safely reach our goal. 

In "Field" status we can take some shots and keep rocking. But this is an "ideal" state of conditioning that is typically achieved by well-trained backpackers during their trips.

Antibiotic Effects Not Limited to Bacteria

Researchers Find Multiple Effects on Soil from Manure from Cows Administered Antibiotics,
Colorado State University, October 9, 2019.

MAIN POINTS

Bovine Antibiotics
"...more stringent use of antibiotics in medical settings, the use of antibiotics in the livestock sector is gaining increased attention."

Levels of Use
"In the U.S., 80 percent of antibiotics are used in livestock production. Globally, livestock antibiotic use is projected to increase by 67 percent by the year 2030."

The Study
"...researchers analyzed ecosystems exposed to manure from cattle given no antibiotics and manure from cattle given a common antibiotic, as well as a control sample not exposed to manure. All of the manure samples were collected from standard dairy operations maintained by researchers from the Virginia Tech Department of Dairy Science."

Air Pollution Levels tied to Levels of Aggression and Violence

 

HEALTH, FITNESS, POLLUTION & VIOLENCE

When Levels of Aggression and Violence Are, "In the Air..."

Exposure to Air Pollution Increases Violent Crime Rates, Study Finds,
Colorado State University, October 3, 2019.

MAIN POINTS

Bad Air
"...found strong links between short-term exposure to air pollution and aggressive behavior, in the form of aggravated assaults and other violent crimes across the continental United States."

Data
"The CSU researchers cross-analyzed three highly detailed datasets: daily criminal activity from the National Incident-Based Reporting System managed by the FBI; daily, county-level air pollution from 2006-2013 collected by U.S. Environmental Protection Agency monitors; and daily data on wildfire smoke plumes from satellite imagery provided by the National Oceanic and Atmospheric Administration's Hazard Mapping System."

Results
"The research results show a 10 microgram-per-cubic-meter increase in same-day exposure to PM2.5 is associated with a 1.4% increase in violent crimes, nearly all of which is driven by crimes categorized as assaults."

Your Physical Fate Awaits: Aging Slows Fat Cell Turnover

 

HEALTH, FITNESS, FAT, & AGING

Your Physical Fate Awaits

New study shows why people gain weight as they get older,
Karolinska Institutet, September 9, 2019.

MAIN POINTS

Weight Awaits
"Lipid turnover in the fat tissue decreases during ageing and makes it easier to gain weight, even if we don't eat more or exercise less than before."

"The results indicate for the first time that processes in our fat tissue regulate changes in body weight during ageing in a way that is independent of other factors."

"Obesity and obesity-related diseases have become a global problem."

"Understanding lipid dynamics and what regulates the size of the fat mass in humans has never been more relevant."

Always the Same Solution
EXERCISE
"Prior studies have shown that one way to speed up the lipid turnover in the fat tissue is to exercise more."

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."

Any Exercise Prolongs Life

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.)"

PFAS. What's Really Inside Your Body?

 

 

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..."

Autism Increase Linked to Endocrine Disruptors in Womb

 

 

HEALTH, FITNESS, & UBIQUITOUS ENDROCRINE DISRUPTORS FROM PLASTIC USE & WASTE

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."

New Fungal Champion
Pericosine A
"...researchers...have identified a compound from fungi that safely and effectively neutralizes skunk spray odor."

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."

Veillonella Gut Bacteria that Turns Soreness Into Energy

 

HEALTH, FITNESS, & SUPERIOR GUT BACTERIA

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."
