Scientists to track critically endangered tope sharks in the Solent

One of Britain’s largest and most endangered sharks is to be tracked through the busy waters of the Solent, following a £230,000 research grant awarded to scientists at the University of Portsmouth – part of the largest ever government investment in recovering England’s threatened wildlife.

The tope shark, listed as critically endangered on the IUCN Red List, can grow to nearly two metres in length, yet remains largely invisible to the public despite living in some of the UK’s most heavily trafficked coastal waters.

Facing sustained pressure from overfishing, bycatch, habitat loss and wider environmental change, tope populations have declined significantly across their global range.

NVIDIA Nemotron 3 Ultra is offering leading performance at lower cost than top closed models with the largest and most widely adopted AI agent orchestration platform. LangChain tuned its Deep Agents harness for NVIDIA Nemotron 3 Ultra, achieving the highest accuracy among open models, while completing more tasks at higher throughput and running at 10x

Pioneers of Aeronautical Engineering: Dale Reed — Father of the Lifting Bodies

Dale Reed transformed aerospace research through his pioneering work on lifting bodies and remotely piloted research vehicles. His innovations laid the foundation for the Space Shuttle’s design and advanced unmanned flight testing, making him one of NASA’s most influential flight research engineers.

Extremely Large Telescope reaches a major milestone

The Extremely Large Telescope just passed a serious milestone while coming together. But it’s not done yet; the immense telescope is about to get even larger.

The European Organization for Astronomical Research in the Southern Hemisphere (ESO)’s Extremely Large Telescope is under construction on a mountaintop in Chile.

Coining the Technological Singularity

Everybody writes about the Singularity now. Almost nobody knows where the word was born.

Not in a lab. Not in a think tank. In the January 1983 issue of Omni magazine, where a mathematician and science fiction writer named Vernor Vinge put a name to the thing the rest of us are still trying to survive.

Think about that. Four decades before ChatGPT, before the AI arms race, before every futurist and their algorithm started forecasting the end of the human era, the framework already existed. Vinge saw the curve. He just needed a word for the point where it goes vertical.

Today, that word is inescapable. Write about AI, about the future of work, about what happens to humanity when the machines get smarter than us, and you are writing about the Singularity, whether you use the term or not. Refuse to, and you owe your reader an explanation for why not. So you are still writing about it.

Thanks to Josh Calder, who dug out and scanned the original page, you can see the exact moment the term entered our vocabulary. A little piece of digital history, hiding in plain sight for 40 years.

Where do you think we are on Vinge’s curve right now? #Singularity #ArtificialIntelligence #Futurism.

A blood protein can flag dementia risk decades before symptoms appear

Forgetting the name of a loved one may be one of the first signs people notice of dementia, but it’s rarely the first warning sign your brain gives. Changes in the brain that lead to neurodegenerative diseases like Alzheimer’s and dementia start showing up decades before symptoms arrive, and the chemicals at work inside the body can often tip us off to these changes well ahead of time.

A recent study found that a blood protein called GDF15, which is released when cells are under stress, could serve as one of the earliest warning signs of dementia. After tracking more than half a million people for 15–25 years, researchers discovered that those with higher GDF15 levels before age 55 were significantly more likely to develop dementia later in life. Finding that protein in the blood was a much stronger predictor of vascular dementia than Alzheimer’s disease and related dementia.

This opens the possibility that a simple blood test in midlife, one that checks for GDF15, could help doctors flag who is at higher risk of dementia decades down the line. The findings are published in Science Advances.

Israeli research offers new hope for overcoming one of the deadliest brain cancers

The researchers then tested BA-101 together with temozolomide and found that the combination was more effective than either treatment alone. In experiments using mouse models, the combined therapy significantly reduced tumor growth, suggesting that targeting the cancer cells’ resistance mechanism could make existing chemotherapy more powerful.

“Temozolomide resistance remains one of the biggest obstacles in treating glioblastoma,” said Amal. “Our findings suggest that targeting nitrosative stress can restore the tumor’s sensitivity to treatment. While additional studies are needed before this approach can reach patients, these results open an exciting new direction for developing more effective therapies against one of the deadliest cancers.”

The researchers said their findings could point to a new approach in cancer treatment: instead of replacing existing drugs, future therapies could focus on blocking the mechanisms that allow tumors to resist them. If further studies confirm the findings, disabling these survival pathways could allow treatments that have become less effective to regain their ability to attack cancer cells.
