Artificial intelligence is already upending geopolitics

Posted by in categories: biotech/medical, ethics, law, nanotechnology, robotics/AI, security

The TechCrunch Global Affairs Project examines the increasingly intertwined relationship between the tech sector and global politics.

Geopolitical actors have always used technology to further their goals. Unlike other technologies, artificial intelligence (AI) is far more than a mere tool. We do not want to anthropomorphize AI or suggest that it has intentions of its own. It is not — yet — a moral agent. But it is fast becoming a primary determinant of our collective destiny. We believe that because of AI’s unique characteristics — and its impact on other fields, from biotechnologies to nanotechnologies — it is already threatening the foundations of global peace and security.

The rapid rate of AI technological development, paired with the breadth of new applications (the global AI market size is expected to grow more than ninefold from 2020 to 2028) means AI systems are being widely deployed without sufficient legal oversight or full consideration of their ethical impacts. This gap, often referred to as the pacing problem, has left legislatures and executive branches simply unable to cope.

Swiss Scientists crack muscle recovery, repairing age-related fatigue

Posted by in categories: biotech/medical, chemistry, life extension

A new supplement that stimulates a natural body process also promotes muscle recovery in humans. New research indicates that urolithin A can play an important role in improving muscles and prolonging activity – this is especially important as muscles decline with age, exposing us to the dangers of frailty.

Longevity. Technology sponsored content: As fast as we are unlocking the secrets of urolithin A we are also discovering obstacles. Urolithin A boosts mitochondrial and muscle function for sure, but it’s a metabolite, meaning it is made by the body from raw materials that we get from fruits, especially pomegranates; however, not everyone can make sufficient quantities of this antiaging molecule, and that’s where Mitopure steps in.

It seems to be universally accepted that the older we get, the more easily we get tired and the less energy we have – but perhaps it doesn’t have to be this way. The secret lies in our mitochondria, tiny organelles that pack a mighty punch when it comes to energy production. These minute powerhouses take oxygen and glucose and create a chemical called adenosine triphosphate (ATP) and this is the energy our bodies use for movement, growth and repair.

20 years in, Genentech persists and perseveres in Alzheimer’s with gantenerumab

Posted by in categories: biotech/medical, health, neuroscience

Genentech’s Gregory Rippon, M.D., associates a few different phrases with the challenging nature of Alzheimer’s disease drug development: “cautious optimism,” “steady progress,” “an exercise in per | Genentech has been working on gantenerumab for 20 years, and, while it’s tempting to try to rush the clinical process, the Roche unit is slowly but surely following the evidence.

CMS made the wrong decision on Aduhelm. But there might be a silver lining

Posted by in categories: biotech/medical, neuroscience

CMS officials disagree with the FDA’s reasoning, and are likely worried about the cost of covering a medication for hundreds of thousands of beneficiaries who might seek the treatment if it was broadly covered by Medicare. While CMS’s concern for taxpayers is understandable, it’s the FDA — not CMS — that has the statutory authority and deep medical expertise to assess a drug for approval. And Aduhelm passed the FDA’s assessment.

CMS arguably overstepped the bounds of its authority. Its decision is a huge blow to millions of Americans living with Alzheimer’s and their families. They are the losers in CMS’s decision, not only from the severe restriction on access to Aduhelm but also from its chilling effect on the development of other disease-modifying agents for people with Alzheimer’s. If CMS won’t pay for a treatment after the FDA legally approves it, why should a company bother pursuing this pathway?

CMS’s decision will affect the exploration for new treatments for Alzheimer’s for years, just at the time when new drugs appear to be making progress against this terrible disease.

Over 5,000 Previously Unknown Viruses Have Been Discovered Lurking in The Oceans

Posted by in categories: biotech/medical, genetics

An analysis of the genetic material in the ocean has identified thousands of previously unknown RNA viruses and doubled the number of phyla, or biological groups, of viruses thought to exist, according to a new study our team of researchers has published in the journal Science.

RNA viruses are best known for the diseases they cause in people, ranging from the common cold to COVID-19. They also infect plants and animals important to people.

Brainstem Atrophy Is Linked to Extrapyramidal Symptoms in Frontotemporal Dementia

Posted by in categories: biotech/medical, neuroscience

Summary: Patients who suffer from frontotemporal dementia with extrapyramidal symptoms have brainstem atrophy and reduced metabolic activity in specific brain regions compared to those with FTD without extrapyramidal symptoms.

Frontotemporal dementia patients with extrapyramidal symptoms have brainstem atrophy and reduced metabolism in certain areas of the brain significantly more often than patients without extrapyramidal symptoms, a new study from the University of Eastern Finland shows. This observation can facilitate differential diagnostics in frontotemporal dementia.

42 previously unknown genes discovered for Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

A unprecedented global study of Alzheimer’s disease has uncovered an additional 42 genes that may affect a person’s risk of developing the disorder. Doctors hope to use that information to develop a more precise way to identify risk.
