Tapping into the molecular fountain of youth

Posted by in categories: biotech/medical, life extension

At just 40 years old, Kristen Fortney has spent more than half of her life thinking about the science of aging. But why?

“When I get asked this question I usually blame it on reading too much science fiction,” the CEO and co-founder of the clinical-stage biotech BioAge Labs said with a laugh. “My co-founder, Eric Morgen, and I have been talking about aging since high school.”

First measurements of hydrogen-boron fusion in a magnetically confined fusion plasma

Posted by in categories: nuclear energy, particle physics, sustainability

As fusion developers around the world race to commercialize fusion energy, TAE Technologies has pioneered the pursuit of the cleanest and most economical path to providing electricity with hydrogen-boron (also known as p-B11 or p11 B), an abundant, environmentally sound fuel. Today the company is announcing, in collaboration with Japan’s National Institute for Fusion Science (NIFS), a noteworthy research advancement: the first-ever hydrogen-boron fusion experiments in a magnetically confined fusion plasma.

In a paper published by Nature Communications, scientists explain the outcome of the nuclear reaction of hydrogen-boron in an experiment in NIFS’ Large Helical Device (LHD). This paper describes the experimental work of producing the conditions necessary for hydrogen-boron fusion in the LHD plasma and TAE’s development of a detector to make measurements of the hydrogen-boron reaction products: helium nuclei, known as alpha particles.

The finding reflects years of collaborative international scientific fusion research, and represents a milestone in TAE’s mission to develop commercial fusion power with hydrogen-boron, the cleanest, most cost-competitive, and most sustainable cycle for fusion.

Robots let ChatGPT touch the real world thanks to Microsoft

Posted by in categories: drones, robotics/AI

Last week, Microsoft researchers announced an experimental framework to control robots and drones using the language abilities of ChatGPT, a popular AI language model created by OpenAI. Using natural language commands, ChatGPT can write special code that controls robot movements. A human then views the results and adjusts as necessary until the task gets completed successfully.

In a demonstration video, Microsoft shows robots—apparently controlled by code written by ChatGPT while following human instructions—using a robot arm to arrange blocks into a Microsoft logo, flying a drone to inspect the contents of a shelf, or finding objects using a robot with vision capabilities.

Molecular atlas of spider silk production could help bring unparalleled material to market

Posted by in categories: biotech/medical, materials

Researchers from Southwest University in China have constructed the entire chromosomal-scale genome assembly and complete spidroin gene set of the golden orb-weaving spider, Trichonephila clavata, known for its especially strong, golden-colored webs.

They attest that their work “Provides multidimensional data that significantly expand the knowledge of spider dragline silk generation…” and the researchers plan on using this new “molecular atlas” to better understand how spiders manufacture their silk.

Published in the journal Nature Communications, the paper details the steps the researchers took, from wild spider capture to multiomic analysis, in revealing the interplay of genes within the spider’s major ampullate gland, the gland responsible for producing dragline silk.

Most detailed geological model reveals Earth’s past 100 million years

Posted by in category: climatology

Climate, tectonics and time combine to create powerful forces that craft the face of our planet. Add the gradual sculpting of the Earth’s surface by rivers and what to us seems solid as rock is constantly changing.

However, our understanding of this dynamic process has at best been patchy.

Scientists today have published new research revealing a detailed and dynamic model of the Earth’s surface over the past 100 million years.
