Scientists are now planning to ‘grow’ ice and ‘refreeze’ Arctic Sea

Posted by in categories: climatology, sustainability

An innovative way is being created by scientists which will help them in “growing” ice and doing the impossible job of “refreezing” the Arctic Sea as initial tests prove promising.

Scientists are aiming at pumping seawater over the frozen Arctic Ocean. They have carried out trials in the Canadian Arctic which have seen sea ice getting thickened successfully.

According to a report published in New Scientist, if no action is taken right now, the accelerating climate change will make the Arctic “ice-free in the summer in the 2030s” which will be disastrous for the planet.

Revolutionizing Lunar Exploration: Inside NASA’s New Moon Rover

Posted by in category: space travel

NASA is developing a new Lunar Terrain Vehicle (LTV) for the Artemis missions to the Moon, enabling astronauts to explore more expansively and conduct in-depth scientific research.

The Ground Test Unit (GTU), a prototype, is being tested on Earth to evaluate different rover concepts and ensure reliability and functionality before deployment. This initiative includes collaborations with three vendors and aims to bolster technological advancements for future lunar and Martian explorations.

Gut Microbiome Influences Location of Immune Cells, study finds

Posted by in category: biotech/medical

Researchers at the Experimental and Clinical Research Center of Max Delbrück Center and Charité — Universitätsmedizin Berlin (ECRC) have found that different anatomical sections of the gastrointestinal tracts of mice carry different compositions of microbial communities. Moreover, the specific makeup of the microbiota can influence the type and abundance of immune cells in any particular region. The study, which was published in Gut Microbes, maps the complex spatial organization of immune cells and microbial communities, providing a tool for studying the interaction between gut microbes and inflammatory diseases.

Previous research has hinted at the existence of “hotspots” along the GI tract where specific immune cells and microbes might interact more intensely.

But no one had systematically investigated this across the entire gut, says Dr. Hendrik Bartolomaeus, in the Immune-Microbial Dynamics in Cardiorenal Disease lab of Dr. Nicola Wilck, and an author of the study.

Invisibility cloaks? Wave Scattering Simulation Unlocks Potential for Advanced Metamaterials

Posted by in categories: materials, particle physics

New software simulates complex wave scattering for metamaterial design. Could invisibility cloaks become a reality? New research brings this science fiction concept a step closer, with a breakthrough software package that simulates how waves interact with complex materials.

A new software package developed by researchers at Macquarie University can accurately model the way waves — sound, water or light — are scattered when they meet complex configurations of particles.

This will vastly improve the ability to rapidly design metamaterials — exciting artificial materials used to amplify, block or deflect waves.

It’s Just an Anomaly: New Study Challenges Decades-Old Theory of Rapid Evolution

Posted by in categories: asteroid/comet impacts, evolution, existential risks

For decades, researchers have noticed that the pace of evolution tends to speed up over shorter time frames, such as five million years compared to fifty million years. This general trend indicates that “younger” groups of organisms, in evolutionary terms, tend to exhibit higher rates of speciation, extinction, and body size evolution, among other differences from older groups.

Evolutionary processes appear to operate at different time scales, perhaps necessitating the need for a new theory linking microevolution and macroevolution. The larger question has tantalized scientists: why?

There are plausible explanations. A new species may inhabit a new island chain, allowing for more variation as it spreads into new niches. An asteroid may hit the earth, increasing extinction rates. Perhaps species evolve to an “optimal” trait value and then plateau.

WATCH LIVE: The winner of the 2024 Nobel Prize in physics is … | PBS News

Posted by in category: physics

The recipient of the 2024 Nobel Prize in physics will be announced Tuesday, Oct. 8.

The winner will be announced no earlier than 5:30 a.m. EDT. Watch the event live in the player above.

Three researchers won the honor last year for making advances in the field of studying electrons. The prize went to French-Swedish physicist Anne L’Huillier, French scientist Pierre Agostini and Hungarian-born Ferenc Krausz, who used attosecond-long flashes of light to illuminate molecules and provide brief glimpses of how fast-moving electrons travel.
