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."

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."

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.

Your Digital Deadweight Brain

Research reveals how the Internet may be changing the brain,
NICM Health Research Institute, Western Sydney University, June 5, 2019.

MAIN POINTS

Cell Phonyism
"The key findings of this report are that high-levels of Internet use could indeed impact on many functions of the brain."

Stupid Phones
"...international team of researchers...have found the Internet can produce both acute and sustained alterations in specific areas of cognition, which may reflect changes in the brain, affecting our attentional capacities, memory processes, and social interactions."

Individual and Social Effects
"Instagramification of society"
"I believe that this, along with the increasing #Instagramification of society, has the ability to alter both the structure and functioning of the brain, while potentially also altering our social fabric."

Digital Hole
"It's clear the Internet has drastically altered the opportunity for social interactions, and the contexts within which social relationships can take place."

HEALTH & FITNESS

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: Marathon Training 'Reverses' Aging of Blood Vessels

 

HEALTH & FITNESS

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."

Two Fitness Research Summaries:
Food and Proper Forms for Superior Performance

Muscle Power & Protein Intake

 

1> POWER

Ability to lift weights quickly can mean a longer life,
European Society of Cardiology, April 12, 2019.

MAIN POINTS

“Prolong your life by increasing your muscle power.”

“...people with more muscle power tend to live longer.”

The Key: Power
“Power depends on the ability to generate force and velocity, and to coordinate movement.”

Power Forms
"Power training is carried out by finding the best combination of speed and weight being lifted or moved. For strength training at the gym most people just think about the amount of weight being lifted and the number of repetitions without paying attention to the speed of execution. But for optimal power training results, you should go beyond typical strength training and add speed to your weight lifts."

HEALTH & FITNESS NEWS: Dangers of High Intensity Exercise

 

HEALTH & FITNESS

High Intensity Exercise

High-intensity interval training increases injuries, Rutgers study finds,
Rutgers University, April 9, 2019.

MAIN POINTS

Interval Training
"These workouts, which combine aerobic exercising, weight lifting and calisthenics at maximum capacity, followed by periods of recovery, have been growing in popularity over the past decade, driven by the efficiency of the exercise to deliver fitness goals in less time."

DANGER
"People who engage in high-intensity interval training are at greater risk for injury, especially in the knees and shoulders."

Effective but Dangerous
"...acknowledged that while this type of training is effective in improving cardiorespiratory fitness, boosting energy and promoting lean muscle mass and fat loss, it also increases injury risk."

Why
Improper Prep
"...many athletes, especially amateurs, do not have the flexibility, mobility, core strength and muscles to perform these exercises."

Exercise has Anti-Inflammatory Effect Preventing Osteoarthritis Cartilage Damage

 

HEALTH & FITNESS

Exercise has Anti-Inflammatory Effect

Exercise helps prevent cartilage damage caused by arthritis,
Queen Mary University of London, March 27, 2019.

MAIN POINTS

Exercise Good
“Exercise helps to prevent the degradation of cartilage caused by osteoarthritis...”

Movement is Anti-Inflammatory
“During exercise the cartilage in joints such as the hip and knee is squashed. This mechanical distortion is detected by the living cells in the cartilage which then block the action of inflammatory molecules associated with conditions such as arthritis.”

“…this is down to tiny hair-like structures called primary cilia found on living cells.”

Why
“...this anti-inflammatory effect of physical activity is caused by activation of a particular protein, called HDAC6, which triggers changes in the proteins that form primary cilia.”
