Is life a complex computational process?

Posted by in categories: biotech/medical, chemistry, computing, genetics

However, more recent research suggests there are likely countless other possibilities for how life might emerge through potential chemical combinations. As the British chemist Lee Cronin, the American theoretical physicist Sara Walker and others have recently argued, seeking near-miraculous coincidences of chemistry can narrow our ability to find other processes meaningful to life. In fact, most chemical reactions, whether they take place on Earth or elsewhere in the Universe, are not connected to life. Chemistry alone is not enough to identify whether something is alive, which is why researchers seeking the origin of life must use other methods to make accurate judgments.

Today, ‘adaptive function’ is the primary criterion for identifying the right kinds of biotic chemistry that give rise to life, as the theoretical biologist Michael Lachmann (our colleague at the Santa Fe Institute) likes to point out. In the sciences, adaptive function refers to an organism’s capacity to biologically change, evolve or, put another way, solve problems. ‘Problem-solving’ may seem more closely related to the domains of society, culture and technology than to the domain of biology. We might think of the problem of migrating to new islands, which was solved when humans learned to navigate ocean currents, or the problem of plotting trajectories, which our species solved by learning to calculate angles, or even the problem of shelter, which we solved by building homes. But genetic evolution also involves problem-solving. Insect wings solve the ‘problem’ of flight. Optical lenses that focus light solve the ‘problem’ of vision. And the kidneys solve the ‘problem’ of filtering blood. This kind of biological problem-solving – an outcome of natural selection and genetic drift – is conventionally called ‘adaptation’. Though it is crucial to the evolution of life, new research suggests it may also be crucial to the origins of life.

This problem-solving perspective is radically altering our knowledge of the Universe. Life is starting to look a lot less like an outcome of chemistry and physics, and more like a computational process.

The Moon was once covered by an Ocean of Molten Rock, data from India’s Space Mission suggests

Posted by in category: space

Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature.

On August 23, 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which had been stowed on Vikram, to explore the landing site.

The location where Vikram touched down was further south than any other landing craft had previously been on the moon. It gave scientists an insight into the geology of the moon that had not yet been sampled.

What if everything you thought about coding was wrong?

Posted by in categories: business, government, robotics/AI

Jensen Huang, Nvidia’s visionary CEO, challenges a long-held belief about the future of programming. While everyone has been saying it’s crucial to learn coding, Huang turns that idea on its head. With the rise of AI, we are ALL programmers now – without ever writing a line of code.

The real miracle is here: artificial intelligence. It has closed the gap between humans and technology, making complex computing accessible to all. Whether you’re a professional or someone just dipping their toes into the world of tech, AI is now in your hands. Are you going to let this chance slip by? The time to act is now! 🌍🤖

The technology divide is no more. Every government, industry, and business is investing in AI. Will you get on board, or be left in the dust?

Using sunlight to turn two greenhouse gases into valuable chemicals

Posted by in categories: chemistry, climatology, sustainability

McGill University researchers have harnessed the power of sunlight to transform two of the most harmful greenhouse gases into valuable chemicals. The discovery could help combat climate change and provide a more sustainable way to produce certain industrial products.

“Imagine a world where the exhaust from your car or emissions from a factory could be transformed, with the help of sunlight, into clean fuel for vehicles, the building blocks for everyday plastics, and energy stored in batteries,” said co-first author Hui Su, a Postdoctoral Fellow in McGill’s Department of Chemistry. “That’s precisely the kind of transformation this new chemical process enables.”

The research team’s new light-driven chemical process converts methane and carbon dioxide into green methanol and carbon monoxide in one reaction. Both products are highly valued in the chemical and energy sectors, the researchers said.

Boeing Execs Have Been Suspiciously Quiet Ever Since Starliner Limped Back to Earth

Posted by in category: space

Over the weekend, the aerospace giant’s Starliner softly touched down in the New Mexico desert, bookending a disastrous first crewed test flight.

But NASA astronauts Butch Wilmore and Suni Williams are still stranded on board the International Space Station after the space agency deemed Starliner too dangerous for their return.

And instead of trying to spin the landing into a victory, Boeing executives have been eerily quiet since. Two executives who were scheduled to speak at a post-landing press conference at NASA’s Johnson Space Center, seemingly decided last minute not to show up.

Gravity Mapping Detects Large Hidden Structures Under Surface of Mars

Posted by in categories: government, mapping, space

A new analysis of Mars’ gravitational field has revealed hidden structures buried beneath the remains of an ancient ocean.

The work, which was presented this week at the Europlanetary Science Congress in Berlin, could add to a growing body of evidence that suggests the Red Planet may not be as geologically “dead,” or inactive, as once believed.

Overlaid with a thick and smooth layer of sediment which may have once been a seabed, the structures are significantly denser than their surroundings — though a more precise explanation of what they might be has so far eluded researchers.
