Anxiety over academics. Post-lockdown malaise. Social media angst.

Study after study says American youth are in crisis, facing unprecedented mental health challenges that are burdening teen girls in particular. Among the most glaring data: A recent Centers for Disease Control and Prevention report showed almost 60% of U.S. girls reported persistent sadness and hopelessness. Rates are up in boys, too, but about half as many are affected.              Continue reading

TECHNOLOGY: Why OpenAI’s ChatGPT Is Such A Big Deal – video

OpenAI, which Elon Musk helped to co-found back in 2015, is the San Francisco-based startup that created ChatGPT.

The company opened ChatGPT up for public testing in November 2022. In under a week, the artificial intelligence model amassed over a million users, according to OpenAI’s CEO, Sam Altman. By the end of January, ChatGPT was averaging about 13 million visitors per day. Users have had ChatGPT write everything from essays, to lyrics and even correct computer code. ChatGPT is part of a growing field of AI known as generative AI, which allows users to create brand new content including videos, music and text. But generative AI still faces a number of challenges, such as developing content that is inaccurate, biased or inappropriate.

Now enterprises and the public are wondering what wide access to AI will mean for businesses and society. Chapters: 00:00 — Intro 01:36 — Chatting with ChatGPT 03:03 — Understanding ChatGPT 06:39 — Use cases and limitations 10:09 — Future implications

Ian on Sunday – The unrelenting hustle of life – By Ian McDonald

Our lives of such infinite value come and go in a whirl of busyness.  We hasten and hustle and there is never enough time and always too much information.  The hours trip over themselves as they pass into eternity.  You will never have them back so regret every one not spent as you would really wish them to be spent.

SCIENCE: ‘Bees are really highly intelligent’: the insect IQ tests causing a buzz among scientists

We all know these busy insects are good for crops and biodiversity, but proof is emerging that they are also clever, sentient and unique beings

They have been revered by the ancient Egyptians, lauded by Shakespeare, feared by Winnie-the-Pooh and, most recently, battled by Rowan Atkinson in the new Netflix hit Man vs Bee. But love or loathe them, you may be surprised to discover just how much bees know.

“We now have suggestive evidence that there is some level of conscious awareness in bees – that there is a sentience, that they have emotion-like states,” says Lars Chittka, professor of sensory and behavioural ecology at Queen Mary University of London.        Continue reading

USA: How the US could lose the new Cold War – By Joseph E. Stiglitz

By Stabroek News –  June 27, 2022

 By Joseph E. Stiglitz

NEW YORK – The United States appears to have entered a new cold war with both China and Russia. And US leaders’ portrayal of the confrontation as one between democracy and authoritarianism fails the smell test, especially at a time when the same leaders are actively courting a systematic human-rights abuser like Saudi Arabia. Such hypocrisy suggests that it is at least partly global hegemony, not values, that is really at stake.

For two decades after the fall of the Iron Curtain, the US was clearly number one. But then came disastrously misguided wars in the Middle East, the 2008 financial crash, rising inequality, the opioid epidemic, and other crises that seemed to cast doubt on the superiority of America’s economic model. Moreover, between Donald Trump’s election, the attempted coup at the US Capitol, numerous mass shootings, a Republican Party bent on voter suppression, and the rise of conspiracy cults like QAnon, there is more than enough evidence to suggest that some aspects of American political and social life have become deeply pathological.                Continue reading

ENERGY: SOLAR: Journey to the Sun with me – By Dave Rohee

Journey to the Sun with me – By Dave Rohee

Solar Panels

This is a fascinating trip and definitely worth your time! In this time of uncertainty regarding climate change, historic wildfires, relentless hurricanes, and devastating floods, we need to be more aware of our dangerous situation caused by weather.

By that, I mean, we have squandered our planet’s resources and hastened its demise to an uncertain future. It may be well beyond our imagination to even comprehend the challenges the future generations will face. But that is a discussion for another time.

You do not have to believe in climate change to understand the recent weather-related phenomena that have gripped our small part of the planet.

What I want to talk about today is our primary source of light and heat – The Sun!          Continue reading

USA: Expose the racism of the fig leaf which covers up ‘replacement theory’ – By Mohamed Hamaludin

U.S. — Time to rip away the fig leaf of ‘replacement’ and expose the racism which it covers up

By MOHAMED HAMALUDIN

The 18-year-old European American male who killed 10 African Americans on May14 at a Buffalo, New York, supermarket surveyed the store located more than 200 miles from his hometown to be sure he could kill the largest number of African Americans. He posted a 180-page manifesto which cited the “replacement theory” – a belief that there is a plot to replace European Americans with people of other races — and 672 texts indicating that he decided since February to kill “replacers.”

How could such a young man, not yet out of his teens, son of two New York transit department engineers, be filled with such venom? Take your pick:            Continue reading
