Interstellar Intruder: The Cosmic Event That Rewrote Earth’s Climate History

Posted by in categories: climatology, space travel

New astrophysical research highlights a significant cosmic event two million years ago when the solar system passed through a dense interstellar cloud. This possibly altered Earth’s climate by exposing it to enhanced cosmic radiation, supported by increased isotopes found in geological records.

Earth was a very different place around two million years ago, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice ages coming and going until about 12,000 years ago. Scientists theorize that ice ages occur for a number of reasons, including the planet’s tilt and rotation, shifting plate tectonics, volcanic eruptions, and carbon dioxide levels in the atmosphere.

But what if drastic changes like these are not only a result of Earth’s environment, but also the sun’s location in the galaxy?

AI Used to Predict Potential New Antibiotics

Posted by in categories: biotech/medical, chemistry, robotics/AI

A new study used machine learning to predict potential new antibiotics in the global microbiome, which study authors say marks a significant advance in the use of artificial intelligence in antibiotic resistance research…

For this study, the researchers collected genomes and meta-genomes stored in publicly available databases and looked for DNA snippets that could have antimicrobial activity. To validate those predictions, they used chemistry to synthesize 100 of those molecules in the laboratory and then test them to determine if they could actually kill bacteria, including ‘some of the most dangerous pathogens in our society’, de la Fuente said.

New method could allow multi-robot teams to autonomously and reliably explore other planets

Posted by in categories: robotics/AI, space

While roboticists have developed increasingly sophisticated systems over the past decades, ensuring that these systems can autonomously operate in real-world settings without mishaps often proves challenging. This is particularly difficult when these robots are designed to be deployed in complex environments, including space and other planets.

In a recent study published in the journal Nature Medicine, a team of researchers in China conducted a prospective analysis of metabolic multimorbidity clusters based on 21 metabolic parameters to investigate gut microbiome signatures associated with metabolism and age to better understand the relationship between metabolism, age, and the long term risk of cardiovascular disease.

Scientists find 16 “ultra-black” fish species that absorb 99.9% of light

“But what isn’t absorbed side-scatters into the layer, and it’s absorbed by the neighboring pigments that are all packed right up close to it,” Osborn told Wired. “And so what they’ve done is create this super-efficient, very-little-material system where they can basically build a light trap with just the pigment particles and nothing else.”

The result? Strange and terrifying deep-sea species, like the crested bigscale, fangtooth, and Pacific blackdragon, all of which appear in the deep sea as barely more than faint silhouettes.

Twin Moons of Dinkinesh: NASA’s Lucy Unveils a Surprising Discovery

Posted by in categories: evolution, space

NASA’s Lucy spacecraft’s recent exploration of asteroid Dinkinesh not only highlighted the asteroid’s internal complexities but also led to a fascinating discovery: the formation of a double moon, Selam.

NASA ’s Lucy spacecraft’s November 2023 flyby of asteroid Dinkinesh revealed significant geological features indicating its internal strength and complex history. Images showed a trough, a ridge, and a contact binary satellite, Selam. These findings, suggesting that Dinkinesh responded dynamically to stress over millions of years, help scientists understand the formation and evolution of small bodies in the solar system.
