Drug pollution concentrates in stream bugs, passes to predators in water and on land

HEALTH, FITNESS, OVER-DEVELOPMENT, INSECTS, & DRUGS

Our Behavior is Equal to, or Worse than Pissing in our Own Drinking Water

Drug pollution concentrates in stream bugs, passes to predators in water and on land,
Cary Institute of Ecosystem Studies, November 6, 2018.

MAIN POINTS

Pharmacy in the Creek
“Sixty-nine pharmaceutical compounds have been detected in stream insects, some at concentrations that may threaten animals that feed on them, such as trout and platypus.”

Flying from Creek into Wider Ecosystem
“When these insects emerge as flying adults, they can pass drugs to spiders, birds, bats, and other streamside foragers.”

Global Drugging of Man & Nature
“Pharmaceutical pollution is present in surface waters globally. Drugs enter the environment because most wastewater treatment facilities are not equipped to remove them from sewage. Septic tanks, aging pipes, and sewer overflows contribute to the problem.”

MAIN POINTS

A Lively Supercluster
"A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597. At the core of the central galaxy, a supermassive black hole is powering the cosmic equivalent of a monumental fountain, drawing in vast stores of cold molecular gas and spraying them back out again in an ongoing cycle."

Climate Change Triggering Return of New, & Eradicated Mosquitos & diseases

CLIMATE, SKEETERS, & HEALTH

It’s Already Happening...

Could climate change trigger the return of eradicated mosquito-related disease?
University of Bath, November 5, 2018.

MAIN POINTS

New Ranges
“The largest ever study of the mosquito evolutionary tree, going back 195 million years, suggests that present-day climate change could result in the spread and return of dangerous mosquito-borne diseases to new places or areas where they had previously been eradicated.”

Return of the Classics
“...– including malaria, Yellow fever, Zika virus, and Dengue fever – cause millions of deaths each year. While many of these diseases have been eradicated from Europe and are under control in other parts of the world, resurgence is always possible.”

Bonus for the Skeeters
They Like Heat AND CO2
“...the rate at which new species of mosquitoes evolve generally increases when levels of atmospheric carbon dioxide are higher. This is concerning because the greater the number of mosquito species, the more potential exists for new ways of vectoring diseases, and perhaps for new variants of those diseases.”

Health Effects of Dairy, Salt, Sugar, and Now Protein Consumption Revised-Clarified

SMASHING HEALTH, FITNESS, and FOOD MYTHS

Dairy, Salt, Sugar, and Now Protein Consumption Clarified

Researchers show that a high-protein diet does not affect kidney function,
McMaster University, November 5, 2018.

MAIN POINTS

Meta-analysis
“...challenges the perceived dangers of a protein-rich diet, a notion first introduced in the 1980s which suggested processing large amounts of protein leads to a progressive decline in kidney function over time. ”

“Researchers analyzed data from 28 papers dating from 1975 to 2016, examining the effects of a low/normal protein intake versus higher protein diets on GFR in health individuals. ”

“...the impact of protein on kidney function is much more contentious, particularly its effect on the glomerular filtration rate (GFR), which is a test to measure how well the kidneys filter blood and remove waste. ”

Opposite is True
“...in fact, the evidence shows the contrary is true: higher protein increases, not decreases, kidney function.”

"With these findings, we have shown that a higher protein diet is safe. In fact, it should be viewed as an important tool for muscle health across an entire lifespan."

2018: Descent of the Summer Triangle, Rise of the Winter Circle

ASTROPHYSICS, ASTRONOMY, & THE SEASONS

Descent of the Summer Triangle,
&
Rise of the Winter Circle

November 3, 2018

 

Above
At Sunset today we can easily find the Summer Triangle, as its bright stars dominate the center of the sky, directly above our heads.

“Paper” Sky Map
with link to
Digital Star Wheel

Eastern Horizon
We can also observe the first rise of the Winter Circle, with the rise of Capella in Auriga out of the Northeast at Sunset, giving us our first look at the rising Winter Circle at Sunset, an event also marking out for us the beginning of the seasonal end of the Summer Triangle. By 10 pm PST we are watching Orion rise out of the East, and by Midnight we can see the full structure of the Winter Circle risen, as Sirius leading the Big Dog finally rises above the horizon, completing the Winter Circle.

Western Edge
On the other side of our Night Sky, along the Western Horizon at Midnight, we are observing Altair and Vega of the Summer Triangle poised just above the Western Horizon, with Deneb just above them, their descent almost perfectly balanced and timed with the rising bright stars of the Winter Circle rising out of the East.

Socks: Member's Favorite Backpacking Socks

Members' Favorites

Backpacking Socks

 As High Sierra backpackers display a lot of range in foot wear, so too in socks. Sock companies have reciprociated, producing a wide range of socking solutions.

A Thought: When I test and purchase my boots I bring in the sets of inserts I am going to use, along with what I figure will be the primary sock used with that boot. Summer? A medium to light sock. Winter? Heavy socks with maybe even a liner sock...

I typically bring the wool sock for the Backpacking Season. Light for Summer, medium for Spring and Fall, and heavy for Winter. Sock liners come along during some Winter trips.

I will use cotton socks during Heat Waves! They are so much more comfortable during hot conditions.

Stoves: MEMBERS FAVORITES for High Sierra Backpacking

Members Favorites

High Sierra
Backpacking Stoves

We have considerable range of selections from a wide range of fuels and gasses, delivery systems (below), wind shields and pot supports, not to mention the ability to construct a wide range of homemade alchol stoves.

I figure the benefit of some wisdom and experience will help us sort this all out, and find the stove that best suites us. Thus we poll our members for their preferences. Since we have lots of different types of members with lots of different types of goals and experiences we come up with a range of classic solutions.

Well, at least a good place for you to begin your investigation into what's the best backpacking stove for you.

 The Existential Zone

Research increases distance at which supernova would spark mass extinctions on Earth
UNIVERSITY OF KANSAS, May 11, 2017.

 

ISSUE:

“The Supernova Kill Zone,”

“The Big Rock from Space,”

along with

Super-Volcanos,

and Humans:

Q: Which term above is different from the others?

A: Humans. The other events were not created by will and choice, but by Nature.

 

UPDATES
BELOW

 

IMPORTANT QUESTIONS

Every now and again Nature kills everything on a planet, on a regular basis. This brings up important questions for an evolving life form, once they figure out death is coming for them.

The spectre of inevitable extinction, if not our typical, individual deaths, makes important the broader questions of what are we as living things, and what Nature itself is doing with Life. Nature's "big program" could be used to give some context to our individual lives by understanding what IT is doing and where IT is going, contrasted against our behavior.

2016 Costs of Obesity Exceeded $1.7 Trillion

HEALTH, FITNESS, & FAT-ASSEDNESS

Destructive Consumption Destroying Mind & Body of Mankind

Economic impact of excess weight now exceeds $1.7 trillion,
Milken Institute, October 31, 2018.

MAIN POINTS

“The prevalence of obesity in the U.S. population has increased steadily since the 1960s—from 3.4 percent of adults in 1962 to 39.8 percent in 2016”

Nation of Fatties
“In all, 180.5 million people—or 60.7 percent of the population ages 2 and over—were either obese or overweight.”

1.7 Trillion Dollar Overeating Problem
“The impact of obesity and overweight on the U.S. economy has eclipsed $1.7 trillion (a year), an amount equivalent to 9.3 percent of the nation's gross domestic product, according to a new...report on the role excess weight plays in the prevalence and cost of chronic diseases.”

"The estimate includes $480.7 billion in direct health-care costs and $1.24 trillion in lost productivity…" (2016)

Wildlife Conservation Society: 77% of Wilderness Gone

ECO-CRASHING NEWS

Vast Majority of Wilderness GONE

A wilderness 'horror story,'
Wildlife Conservation Society, October 31, 2018.

MAIN POINTS

 

77% of Wilderness Gone
“...conservation scientists...say that just 23 percent of the world's landmass can now be considered wilderness, with the rest - excluding Antarctica - lost to the direct effects of human activities.”

End of Wilderness
“These results are nothing short of a horror story for the planet's last wild places. The loss of wilderness must be treated in the same way we treat extinction. There is no reversing once the first cut enters. The decision is forever."

Last Land & Sea Refuges
“Various analyses reveal that wilderness areas provide increasingly important refuges for species that are declining in landscapes dominated by people. In the seas, they are the last regions that still contain viable populations of top predators, such as tuna, marlins and sharks.”

Picaridin Saving more Skeeters than it’s Killing?

MOSQUITOES, HEALTH, & INSECTICIDES

Picaridin Saving more Skeeters than it’s Killing?

Widely used mosquito repellent proves lethal to larval salamanders,
Cary Institute of Ecosystem Studies, October 31, 2018.

MAIN POINTS

Chemical Defense
“Insect repellents are a defense against mosquito bites and mosquito-borne diseases like dengue, chikungunya, Zika, and West Nile virus.”

Natural Defense
“Salamanders provide natural mosquito control. During their aquatic juvenile phase, they forage on mosquito larvae, keeping populations of these nuisance insects in check.”

The Two Don’t Mix
“Chemicals in repellents enter aquatic ecosystems through sewage effluent and are now common in surface waters.”

More Skeeters?
“The paper is the first to suggest that environmentally realistic concentrations of picaridin-containing repellents in surface waters may increase the abundance of adult mosquitoes due to a decrease in predation pressure on mosquitoes at the larval stages.”

Lyme disease predicted to rise in United States as climate warms

CLIMATE, HEALTH, LYME’S, & TICKS

RED ALERT
20% Higher in 30 Years

Lyme disease predicted to rise in United States as climate warms,
Carnegie Mellon University, October 31, 2018.

MAIN POINTS

LYME DISEASE
“...its incidence has risen sharply in the last decade. Since its progression depends on environmental factors, increases in daily temperatures, a manifestation of climate change, might be contributing to a rise in the number of ticks as well as a greater availability of hosts.”

Already Exploding
“The number of reported cases of Lyme disease in the United States rose from 10,000 in 1991 to about 28,000 annually in the past five years.”

Tick Distribution Mirrors Temp & Humidity
“...ticks spend most of their life cycle outside the host in an environment where temperature and humidity directly affect their development, activity, survival, and host-seeking behavior. In fact, the U.S. Environmental Protection Agency uses the number of cases of Lyme disease as an indicator of climate change.”

eLife, October 30, 2018.

MAIN POINTS

FYI
“...an analysis spanning nearly four decades...”

“In this study, we set out to comprehensively characterise the patterns of death over different time periods and geographical areas to understand when and where death rates are at their highest and lowest.”

“…data on 85,854,176 deaths in the US between 1980 and 2016...”

“...several distinct seasonal patterns in relation to age and gender:”
> Deaths from overall mortality (any cause of death) in men aged 45 years and older and women aged 35 years and older peaked in December, January or February, and were lowest in June to August

Is the Long Valley Caldera Hot-Cold Water Boundary Secure?

MAMMOTH LAKES GEOTHERMAL POWER

Is the Long Valley Caldera's Hot-Cold Water Boundary Secure?

Is former Olympian a bully or savior in geothermal fight?
E&ENews, October 29, 2018.

MAIN POINTS

Not Contained?
“Hayes, a charismatic former Olympian, says data show the deep geothermal reservoirs used for energy production are not completely contained. They are already contaminating the town's shallower groundwater aquifers, he says, and the problem could get worse when the plant expands production.”

“...that's what Pat Hayes, the area's water manager, wants you to think.”

“The problem for Hayes, though, is it's unclear how much validity there is to those claims.”

“His critics note that Hayes has secured few victories. Courts have strongly rejected his claims, siding with regulators who reviewed the relevant scientific data, as well as a robust groundwater monitoring plan they've put in place.”

Contained?
“Judge Stan Eller concluded that "available evidence" indicates the groundwater and geothermal systems are separate.”
