From a pile of seaweed to a packet of soy sauce.
The London startup Notpla has created a plastic alternative from seaweed that’s biodegradable — and even edible. And it’s hoping it could put a dent in the 300 million tons of plastic waste humans generate each year.
Notpla’s natural plastic-like casing is biodegradable within four to six weeks, the company says, compared to the several hundred years it takes synthetic plastics to biodegrade.
The technology doesn’t seem to be here yet; obviously, the ice on Mars will be harvested to provide drinking and irrigation water.
If we ever intend to send crewed missions to deep-space locations, then we need to come up with solutions for keeping the crews supplied. For astronauts aboard the International Space Station (ISS), who regularly receive resupply missions from Earth, this is not an issue. But for missions traveling to destinations like Mars and beyond, self-sufficiency is the name of the game.
This is the idea behind projects like BIOWYSE and TIME SCALE, which are being developed by the Centre for Interdisciplinary Research in Space (CIRiS) in Norway. These two systems are all about providing astronauts with a sustainable and renewable supply of drinking water and plant food. In so doing, they address two of the most important needs of humans performing long-duration missions that will take them far from home.
Even though the ISS can be resupplied in as little as six hours (the time between launch and the time a supply capsule will dock with the station), astronauts still rely on conservation measures while in orbit. In fact, roughly 80% of the water aboard the ISS comes from airborne water vapor generated by breathing and sweat, as well as recycled shower water and urine—all of which is treated with chemicals to make it safe for drinking.

With fall and winter holidays coming up, many will be pondering the relationship between food and sleep. Researchers led by Professor Masashi Yanagisawa at the University of Tsukuba in Japan hope they can focus people on the important middlemen in the equation: bacterial microbes in the gut. Their detailed study in mice revealed the extent to which bacteria can change the environment and contents of the intestines, which ultimately impacts behaviors like sleep.
The experiment itself was fairly simple. The researchers gave a group of mice a powerful cocktail of antibiotics for four weeks, which depleted them of intestinal microorganisms. Then, they compared intestinal contents between these mice and control mice who had the same diet. Digestion breaks food down into bits and pieces called metabolites. The research team found significant differences between metabolites in the microbiota-depleted mice and the control mice. As Professor Yanagisawa explains, “we found more than 200 metabolite differences between mouse groups. About 60 normal metabolites were missing in the microbiota-depleted mice, and the others differed in the amount, some more and some less than in the control mice.”
The team next set out to determine what these metabolites normally do. Using metabolome set enrichment analysis, they found that the biological pathways most affected by the antibiotic treatment were those involved in making neurotransmitters, the molecules that cells in the brain use to communicate with each other. For example, the tryptophan–serotonin pathway was almost totally shut down; the microbiota-depleted mice had more tryptophan than controls, but almost zero serotonin. This shows that without important gut microbes, the mice could not make any serotonin from the tryptophan they were eating. The team also found that the mice were deficient in vitamin B6 metabolites, which accelerate production of the neurotransmitters serotonin and dopamine.
Artificial intelligence is being applied to virtually every aspect of our work and recreational lives. From determining calculations for the construction of towering skyscrapers to designing and building cruise ships the size of football fields, AI is increasingly playing a key role in the most massive projects.
But sometimes, all we want to do is move a can of beans.
According to a recently published abstract by researchers at the University of California, Berkeley, they have developed a mechanism that “couples a perception pipeline predicting a target object occupancy support distribution with a mechanical search policy that sequentially selects occluding objects to push to the side to reveal the target as efficiently as possible.”

Ira Pastor ideaXme life sciences ambassador interviews Dr. Angela Hughes, the Global Scientific Advocacy Relations Senior Manager and Veterinary Geneticist at Mars Petcare.
The global petcare industry is significantly expanding, with North America sales alone expected to hit US $300 billion by 2025. And while we may associate the Mars Corporation, the world’s largest candy company, with leading confectionary brands like Milky Way, M&M’s, Skittles, Snickers, Twix, etc. They also happen to be one of the world’s largest companies in pet care as well.
Dr. Angela Hughes, is the Global Scientific Advocacy Relations Senior Manager & Veterinary Geneticist at Mars Petcare. Dr. Hughes is both Doctor of Veterinary Medicine, and a PhD with a focus in Canine Genetics, both from the University of California, Davis. Dr. Hughes also serves as Veterinary Genetics Research Manager of Wisdom Health, a business unit of Mars Petcare, which has developed state-of-the-art genetic tests for companion animals, leading to revolutionary personalized petcare. She also serves as a Veterinary Geneticist of Hughes Veterinary Consulting, focused on small animal and equine genetics and with a special interest in small animal reproduction and pediatrics.
Dr Hughes is published in multiple academic journals, including the Journal of the American Veterinary Medical Association and has contributed chapters for publication in Veterinary Clinics of North America Small Animal Practice: Pediatrics and Large Animal Internal Medicine.
Scientists find that A. echinatior ants have biomineral armour to help them in battle with other ants and protect them from pathogens. 😃
Ants are pretty organised little creatures. Highly social insects, they know how to forage, build complicated nests, steal your pantry snacks, and generally look after the queens and the colony, all by working together.
Leaf-cutter ants turn that cooperation up several notches. Leaf-cutter ant colonies like Acromyrmex echinatior can contain millions of ants, split into four castes that all have different roles to maintain a garden of fungus that the ants eat.
These farming ants might make a top-tier team of gardeners, but that doesn’t mean they don’t get into the occasional scrap, and living in such large groups usually also means facing an increased risk of pathogens.
