New Memorial

For nearly 100 years, Robert E. Lee's 10,000-pound monument rode high over the city of Charlottesville, Virginia. Now, it's been melted into bronze slabs and another memorial in town has risen to national prominence.

It's on the University of Virginia campus, titled the Memorial to Enslaved Laborers. It stands as the antithesis to the Confederacy, honoring the slaves forced to work at the university in the 1800s as carpenters, blacksmiths, roofers, stone carvers and other back-breaking trades.

"All these men, women, and children lived with dignity, resisted oppression, and aspired for freedom. For more than four decades, the entire University was a site of enslavement," according to the UVA President's Commission on Slavery. "Now, we’re confronting our past, uncovering new knowledge, and using that knowledge to teach, heal, and shape the future."     READ MORE...

Electricity From Thin Air

Sure, we all complain about the humidity on a sweltering summer day. But it turns out that same humidity could be a source of clean, pollution-free energy, a new study shows.

"Air humidity is a vast, sustainable reservoir of energy that, unlike solar and wind, is continuously available," said the study, which was published recently in the journal Advanced Materials.

“This is very exciting,” said Xiaomeng Liu, a graduate student at the University of Massachusetts-Amherst, and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

In fact, researchers say, nearly any material can be turned into a device that continuously harvests electricity from humidity in the air.


Air 'contains an enormous amount of electricity'

“The air contains an enormous amount of electricity,” said Jun Yao, assistant professor of electrical and computer engineering at the University of Massachusetts-Amherst and the paper’s senior author.  READ MORE...

Research Under the Water

Imagine working aboard a research station on the ocean floor, watching sea creatures swim past, then venturing out to explore the ocean’s surface. Or being able to examine the impact of climate change on coral reefs from the windows of your undersea research station.

Such facilities have so far been limited, but the National Oceanic and Atmospheric Administration and developers of a proposed new “first of its kind” research laboratory hope to expand the opportunities and help humans learn more about the ocean.

Proteus Ocean Group – co-founded by Fabien Cousteau, grandson of the late ocean exploration pioneer Jacques Cousteau – is developing an “underwater space station of the ocean.” The group plans to build the station nearly 60 feet deep off the coast of Curaçao in the Caribbean by 2026.

NOAA and the ocean group announced this month they will partner to identify research opportunities as plans to build the station move forward, sharing information and scientific expertise.

The research facility would give scientists and the public a rare window on life under the ocean, the partners said. Much like the International Space Station and earlier versions of marine laboratories, aquanauts will live aboard the station as they conduct research and exploration beneath the sea.  READ MORE...

Wildfires Wipe Out 20 Years of Greenhouse Emissions Reductions

California's catastrophic wildfires in 2020 put twice as much greenhouse gas emissions into the air as the state's reductions in those same gases over nearly 20 years – erasing gains going back to 2003, according to a new study.

It's part of a positive feedback loop that's very negative, say the researchers.

"Climate change is creating conditions conducive to larger wildfires. And the wildfires are adding to the greenhouse gases that cause climate change," said lead author Michael Jerrett, a professor in the Department of Environmental Health Sciences at the University of California, Los Angeles.

The historic megafires of 2020 released an estimated 127 million metric tons of carbon dioxide into the air. That compares to the 65 million metric tons of greenhouse gas emissions California was able to reduce between 2003 and 2019, the study, published in this month's edition of the journal Environmental Pollution, showed.  READ MORE...

The Nation's Highest Court

WASHINGTON – Even as the fallout continues over its controversial abortion ruling in June, the Supreme Court is gearing up for a new term in which its conservative majority will wade into questions about race, LGBTQ rights and federal elections.

The nation's highest court has agreed to hear 27 arguments so far – roughly half its expected caseload for the term that will likely end in June 2023.

This guide will be updated throughout the nine-month term.

Affirmative action
Background: Perhaps the most closely watched cases at the Supreme Court this term involve race-conscious admissions policies at Harvard College and the University of North Carolina. Those schools consider race as one of many factors in deciding whether to accept prospective students, a policy that is consistent with current Supreme Court precedent. But an anti-affirmative action group has argued the policies discriminate against Asian American and white candidates in violation of federal law and the Constitution.  READ MORE...

Alcohol in Your Body

The Centers of Disease Control and Prevention says two-thirds of adults in 2018 drank alcohol. How much obviously varies, but no one wants to end the day with a DUI because they mistakenly believed they were sober when that was not the case.

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), an abundance of factors contributes to how long alcohol stays in your system. Misunderstanding these factors makes it difficult to tell whether you’re legally safe to be behind the wheel and can lead to tragic consequences.

How long does alcohol stay in your system?

Healthline.com says how long alcohol stays in your system is dependent upon age, weight, whether you’ve eaten food recently, medications, liver disease and the time between drinks. One cup of beer may stay in one person’s system longer than it will for someone else with a different weight.

The ability to metabolize alcohol slows as you age, health.clevelandclinic.org says. Alcohol will have heightened effects on those with lower weights and smaller body sizes. If you’re drinking on an empty stomach, then the effects of alcohol may be enhanced. Different medications can have dangerous side effects when paired with alcohol. Any present liver conditions can harm your ability to handle alcohol and process it. Binge drinking in a short period will also increase the effects of alcohol, all according to health.clevelandclinic.org and healthline.com.

A shot of liquor is estimated to metabolize in an hour, a pint of beer in two, a glass of wine in three, and several drinks could take multiple hours, according to healthline.com.

The NIAAA estimates that one drink would be metabolized and out of your system after three hours, two drinks after slightly over four hours, three drinks by six hours and four drinks by seven. The NIAAA goes on to state that this is, again, dependent on the factors above.

As for driving, healthline.com advises: "The safest thing you can do is not get behind the wheel after you’ve been drinking."  READ MORE...

Ruining Your Devices

How many smartphones have you dropped and shattered? It’s an awful feeling – seeing it falling to the ground and knowing there’s nothing you can do.

Years ago, I put a tempered glass screen protector on my phone. The best part is when you drop your phone, and the glass gets nicked, you simply remove the protector, and it's good as new. Here’s a link to the brand I have used for years, ESR.

Our devices are big investments. You need to treat your tech well to get your money's worth. Regular maintenance is one way to stay ahead of the game. Tap or click for six checkups to do now to avoid a hefty repair bill later.

Based on calls to my show, emails, and questions posted on my website’s tech support forum, here are five common mistakes that could cost you:

1. You’re charging too much
Do you keep your phone plugged in all the time? Apple says that when your iPhone “remain(s) at full charge for prolonged periods of time, battery health can be affected.”

Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.”

The official word is to keep your phone charged – but not fully charged. Get in the habit of unplugging your tech after it is fully charged.

2. You wait too long to charge your laptop
Laptop batteries have a finite number of charge-discharge cycles. If you frequently let your battery entirely run out of juice, it affects the charge-discharge cycle and diminishes its intended lifespan.

Your laptop battery can also lose efficiency another way. Let’s say you regularly charge your laptop from 30% to 50%, or about 20% each time you charge it. Well, do that five times and you’ll have completed one battery cycle because you’ve charged your laptop 100% in total.

A good rule of thumb is to keep your battery charged to at least 40% most of the time. Tap or click here to check your laptop’s battery health.

3. You go with the cheapest option
If you lose your charger or a USB cable gets frayed, resist the temptation to buy the cheapest replacement. The few dollars you save on a low-cost substitute may very likely negatively affect your device’s performance.

One-size-fits-all charger and cable makers don’t want you to know that often their products do not have the proper voltage needed to work with your specific device. Why does that matter? Your battery may end up not getting the juice it needs to charge fully. Worse, it may erode the battery’s life.  READ MORE...

China Surprises USA With Hypersonic Missiles

China’s recent test of a hypersonic missile – a weapon described as faster, more maneuverable and a greater threat to air-defense systems than a conventional intercontinental ballistic missile – has increased tension between the U.S. and China.

It’s “a very significant event of a test of a hypersonic weapon system, and is very concerning,” Gen. Mark Milley, chairman of the Joint Chiefs of Staff, said in a Bloomberg TV interview Oct. 28. Milley's statement was the first official U.S. acknowledgement of the test.

Hypersonic missiles travel at Mach 5, five times the speed of sound while maneuvering in the atmosphere. That's faster than 3,800 mph. Ballistic missiles can reach 15,000 mph while ascending into space. Warheads travel at about 2,000 mph once they re-enter the Earth's atmosphere.

China's test in August was initially reported by the Financial Times on Oct. 16. The Times said the missile circled the Earth at a low altitude before descending to its target, which it missed by about 19 miles.

Trajectory of China's hypersonic and ballistic missiles


The test is significant because it shows China has made unexpected progress on its hypersonic weapons systems and may initiate a new arms race, the Guardian reported.

The test prompted comparison of a "Sputnik moment," an historical reference to the 1957 launch of the Sputnik satellite by the Soviet Union. That was a shock to Americans who were forced to realize the U.S. was being challenged for technological superiority.

“I don’t know if it’s quite a Sputnik moment, but I think it’s very close to that. It has all of our attention,” Milley told Bloomberg.

However, it's not just the hypersonic vehicle and its maneuverability that has attracted attention, as Foreign Policy reports: It's how the vehicle entered orbit.

It used a version of the Fractional Orbital Bombardment System, a low-orbit missile delivery method developed by the Soviets during the Cold War. A missile descending from low orbit gives less time to be detected.

That method of delivery also means the U.S. could be attacked by flights over the South Pole. American defense systems concentrate on missile attacks from the north.  READ MORE...

The Day Before Thanksgiving and All Is Not Well

We refer to our country as AMERICA and to its citizens as AMERICANS and while that is partially true, it is also wrong because being an AMERICAN refers to both the North, Central and South America continents...  North America is the United States and Canada.  Then we have Central America, and last but not least is South America all of whom are technically considered to be AMERICANS...

Is it not a tad ARROGANT to think of US citizens as the only AMERICANS or is it because we are a tad ignorant and don't know our history as well as we thought we did when graduating from high school?

AND...  now we are at the day before Thanksgiving and we are going to over eat and over indulge in alcohol and in those states where marijuana is legal we are going to over indulge in that as well, without the slightest consideration for the history of the holiday for the most part.

US American citizens care more about what their country can do for them rather than caring about what they can do for their country...  The more we have social programs the less that our citizens do for their country and the more we expect the wealthy to pay for our THANKSGIVING DINNERS....  which is actually a metaphorical statement as to what is happening in the US of A.

AND...  as a senior citizen...  one could say that I don't much care because of what is going to happen to you alone because by then I will be dead...  but, the more we expect our country through the wealthy to do for us, the WEAKER we as a people become.  Not weaker in terms of money or technology or healthcare but weaker MENTALLY and that MENTAL WEAKNESS will start to erode and lessen our LOYALTY to the country that gave us all we have.

ALL IS NOT WELL IN THE US of A not because we do not have the natural resources, the technology, the innovations, the freedoms, and the WEALTH but because we are losing sight of our EDUCATION and KNOWLEDGE and will soon lose our freedoms because of our bliss and military weaknesses.

• CHINA has the largest military in the world today...   the USA is second...
• INDIA has the next largest military and then there is
• NORTH KOREA...
• RUSSIA is in there somewhere but because it is no longer the USSR it is much smaller and then there is the
• MIDDLE EAST and all the rag heads in that area as US American military personnel calls them

AND...  while we think our economy is the largest in the land, we have been fooled again but our insightful leaders and the media they control because in terms of PURCHASING POWER PARITY, the largest economy in the land is now CHINA...

Please pass me another joint to have with my beer or wine or alcohol as the combination is mind blowing...  as I have been told...  and, after we finish our Thanksgiving Meal, lets ride to a fast food and get us a burger...  or, maybe some ice cream...

AND...  if that isn't enough...  check our where the USA ranks globally in terms of education K-12 and it will surprise you that we are number 15th.

AND...  if you really want another surprise and cannot wait for CHRISTMAS do a google search my friends on the FREEST COUNTRIES in the world and you will see that the USA is no longer at the top...  and yet, we are supposedly the ones who have all these freedoms...  well...  guess again...  your liberal government has gradually taken them away from you...  but go ahead and enjoy your thanksgiving...

Check out the CATO INSTITUTE and the PEW RESEARCH CENTER and articles that have been published in the CHICAGO TRIBUNE and USA TODAY and US NEWS and WORLD REPORT if you think my words are deceiving...  and, find out for yourself...  the state our States are in while we over eat, over drink, and get chilled out on marijuana...  the more we give US citizens in the way of social programs, the more the lull them to sleep in beds of ignorance.
