It’s getting harder to harder to ignore the potential disruptive power of AI in research. Scientists are already using AI tools but could the future lead to complete replacement of humans? How will our scientific institutions transform? These are difficult questions but ones we have to talk about in today’s episode.

Creativity has long been considered one of the most difficult aspect of human intelligence for AI to mimic. However, the rise of Large Language Models (LLMs), like ChatGPT, has raised questions about whether AI can match or even surpass human creativity.

Thirty-five years ago, our Cosmic Background Explorer, or COBE, was launched! The satellite was a crucial stepping stone in understanding the cosmic microwave background — the afterglow of the earliest moments of our universe.

Launched from what’s now Vandenberg Space Force Base on Nov. 18, 1989, COBE carried three instruments to space to measure microwave and infrared light across the whole sky. COBE’s observations helped us learn how our universe started and evolved.

COBE discovered that the oldest light in the universe contained tiny temperature variations (red indicates hotter regions, blue colder). These were the seeds for the gravitational formation of structures of galaxies seen in the universe today.

S James Webb Space Telescope: + There are still many questions we want to answer about the early universe, and our missions continue to study it and refine our understanding.

The concept of vectors can be traced back to the 17th century with the development of analytic geometry by René Descartes and Pierre de Fermat. They used coordinates to represent points in a plane, which can be seen as a precursor to vectors. In the early 19th century, mathematicians like Bernard Bolzano and August Ferdinand Möbius began to formalize operations on points, lines, and planes, which further developed the idea of vectors.

Hermann Grassmann is considered one of the key figures in the development of vector spaces. In his 1844 work “Die lineale Ausdehnungslehre” (The Theory of Linear Extension), he introduced concepts that are central to vector spaces, such as linear independence, dimension, and scalar products. However, his work was not widely recognized at the time.

In 1888, Giuseppe Peano gave the first modern axiomatic definition of vector spaces. He called them “linear systems” and provided a set of axioms that precisely defined the properties of vector spaces and linear maps. Hilbert helped to further formalize and abstract the concept of vector spaces, placing it within a broader axiomatic framework for mathematics. He played a key role in the development of functional analysis, which studies infinite-dimensional vector spaces.

As the global population ages, more of us face frightening cognitive decline, personally or in our loved ones. There are over 10 million new cases of dementia globally each year.

But a study published this year suggests up to 13 percent of people diagnosed with dementia in the US may have a misdiagnosis and are instead left struggling with a condition that can be treated.

“Health care providers [must be] made aware of this potential overlap between dementia and hepatic encephalopathy, which is treatable,” said Virginia Commonwealth University hepatologist Jasmohan Bajaj in July.

Astronomers have discovered a pair of young stars near the supermassive black hole at the heart of our galaxy. Studying them can offer a rare glimpse into how stars can endure — at least briefly — the immense gravity exerted by such cosmic behemoths.
