Alzheimer’s diagnosis revamp embraces rating scale similar to cancer

July 16 (Reuters) — Alzheimer’s disease experts are revamping the way doctors diagnose patients with the progressive brain disorder — the most common type of dementia — by devising a seven-point rating scale based on cognitive and biological changes in the patient.

The proposed guidelines, unveiled by experts on Sunday in a report issued at an Alzheimer’s Association conference in Amsterdam, embrace a numerical staging system assessing disease progression similar to the one used in cancer diagnoses. They also eliminate the use of terms like mild, moderate and severe.

The revamp — replacing guidelines issued in 2018 — was prompted by the increased availability of tests detecting key Alzheimer’s-related proteins such as beta amyloid in the blood and new treatments that require confirmation of disease pathology prior to use.

WEBB telescope finds 13 billion year-old active black hole

The James Webb Space Telescope has delivered yet another astounding discovery, spying an active supermassive black hole deeper into the universe than has ever been recorded.

The black hole lies within CEERS 1,019 — an extremely old galaxy likely formed 570 million years after the big bang — making it more than 13 billion years old. And scientists were perplexed to find just how small the celestial object’s central black hole measures.

“This black hole clocks in at about 9 million solar masses,” according to a NASA news release. A solar mass is a unit equivalent to the mass of the sun in our home solar system — which is about 333,000 times larger than the Earth.

Today we’re going explore the unthinkable: How would the United States respond during a Nuclear conflict?

When we first came up with this concept, we aimed to cover the America’s Nuclear Triad and it’s Russian Nuclear War Plan in one concise video, but one video turned into three. So here’s full version of “How Would the United States Fight a Nuclear War?” as it was originally intended. Enjoy!

A world-first spacecraft reentry to Earth is approaching

To avert the extremely remote risk that debris poses to life, ESA is targeting the reentry at a vast expanse of ocean far away from land.

If the manoeuvres are successful, ESA expects to complete the journey in late July or early August. However, as a first-ever attempt at an assisted reentry, it’s not guaranteed to work. If the plan has to be aborted, Aeolus’ natural descent will continue.

But if the mission is accomplished, it will set a new standard for satellite reentry and space junk mitigation.

From Sci-Fi to Reality: Addressing AI Risks — with David Brin

AI had its nuclear bomb threshold. The biggest thing that happens to human technology maybe since the splitting of the atom.

A conversation with Science Fiction author and a NASA consultant David Brin about the existential risks of AI and what approach we can take to address these risks.


David Brin’s advice for new authors.

David Brin’s new WIRED article appraises the chances (nil) of an ‘AI moratorium.’ It then breaks down the three standard ‘AI-formats’ implicitly assumed by almost everyone in the field – corporate puppet, invasive blob, or ‘Skynet’. Formats that can only lead to disaster.
He propose instead a 4th — that AI entities just might be held accountable if they have individuality… even ‘soul’… https://www.wired.com/story/give-ever… Brin’s related NEWSWEEK op-ed (June’22) dealt with ‘empathy bots” that feign sapience. https://www.newsweek.com/soon-humanit… Here also is a YouTube pod where I give an expanded version: • AI is Alive!

Pulsar Fusion has begun development of the largest fusion engine in history, which will allow rockets to reach speeds of more than 800,000 kilometres per hour

Pulsar Fusion has begun construction of the world’s largest rocket engine, which will be fuelled by fusion. Within four years, the British company intends to create an 8-metre-long combustion chamber.

Here’s What We Know

The fusion engine will be based on a very hot plasma trapped inside an electromagnetic field. Now scientists are working on how to keep the plasma in the electromagnetic field. The announcement was made by James Lambert, CFO of the UK-based company.
