If humans ever live on Mars or the Moon long-term, they'll need to grow their own food, but the soil there presents a serious problem. Lunar and Martian regolith, the loose dust and rock covering both surfaces, is nearly nutrient-free, lacks the microbiome Earth soil relies on, and doesn't let water filter through easily.
Researchers reviewing recent space agriculture studies suggest the fix might be surprisingly low-tech: fungi. Arbuscular mycorrhizal fungi (AMF) naturally form partnerships with plant roots on Earth, acting like an extended root system that helps plants pull locked-away nutrients from soil and access water more efficiently. Scientists believe introducing AMF into regolith could essentially jump-start it into something closer to living soil.
This isn't just theory. In one related study, chickpeas grown in lunar soil simulant mixed with AMF and worm compost were able to flower and produce seeds, something they couldn't do in untreated regolith. Other fungi, like Trichoderma, are also being studied for reducing plant stress in these harsh conditions.
It's early-stage research, but it points to biology, not just engineering, as key to sustainable space farming.

Some of the most interesting anti-aging research doesn't come from drugs at all, it comes from bacteria.

Researchers at the Hefei Institutes of Physical Science, Chinese Academy of Sciences, studied a magnetotactic bacterium called Magnetospirillum magneticum AMB-1, a microbe that naturally builds tiny internal magnets called magnetosomes. When they exposed C. elegans worms to this bacteria, the worms lived 43% longer on average, while also showing better neurological function and healthier intestinal tissue in old age.

The key seems to be the bacteria's magnet-making ability specifically. A genetically modified version that couldn't form magnetosomes properly showed no lifespan benefit at all, while the fully magnetic strain performed best.

Digging into the mechanism, researchers found the bacteria reduced iron buildup and a type of cell damage called lipid peroxidation in the worms, both of which drive a form of cell death called ferroptosis that's linked to aging and iron overload. By suppressing ferroptosis, the bacteria appeared to protect the worms' cells from age-related decline.

This is early-stage research in worms, not humans, but it opens an interesting new direction for anti-aging science.

Muscle weakness in older adults is usually blamed on losing muscle mass, but researchers at the University of Missouri think that's only part of the story.

Their team, led by Dr. W. David Arnold, found that age-related weakness, known as sarcopenia, may have less to do with losing motor neurons (the nerve cells that tell muscles to contract) and more to do with those neurons losing their ability to fire repeatedly and reliably. It's less about losing the wiring and more about the signal getting weaker.

To test this, researchers gave aged mice a single dose of a drug called lorcaserin, which targets a specific serotonin receptor known to boost motor neuron excitability. The results were striking: motor neuron signal strength increased by over 50%, motor coordination improved by more than 20%, and grip strength rose by around 12%.

This is the first time a drug has been shown to directly improve motor neuron firing and translate that into measurable strength gains. It's still early, preclinical research in mice, but researchers believe it could eventually lead to human clinical trials for sarcopenia, a condition affecting nearly half of adults over 80.

Around the year 1800, explorer Alexander von Humboldt made a strange observation: he dipped a tropical leaf in water and noticed no oxygen bubbles formed in sunlight, when they normally would. That small mystery pointed to something remarkable happening inside the plant.

Researchers at the University of Vienna have now traced the evolution of this trait using the tree genus Clusia, the only known tree genus that performs CAM photosynthesis, a water-saving strategy where plants absorb CO2 at night instead of during the day. This lets them keep their pores closed during the hot daylight hours, dramatically reducing water loss through evaporation.

By comparing the genomes of three Clusia species, ranging from regular daytime photosynthesis to strong CAM, the team found this trait didn't evolve through one simple change. Instead, ancient genome duplications, followed by millions of years of genetic reshuffling, gene loss, and gene repurposing, produced several different water-saving strategies within the same genus.

Understanding this genetic pathway could eventually help scientists engineer more drought-resistant crops, an increasingly important goal as water scarcity grows worldwide.

Cement production is one of the biggest sources of CO2 emissions worldwide, so researchers have been looking for ways to make concrete part of the solution instead of the problem.

A team led by Srinivasan Revathi tested adding two natural materials, zeolite (a porous mineral) and bamboo biochar (a carbon-rich material made by heating bamboo), into concrete mixes. Both materials have large pore volumes and surface areas, which makes them good at trapping gas molecules, including CO2.

After testing different ratios, they found an optimal mix: 50% zeolite replacing fine aggregate and 1% bamboo biochar replacing cement. This mix increased compressive strength by 7.48% and split tensile strength by 15% compared to regular concrete, while also absorbing about 1.2 grams of CO2 per day in lab testing.

That means this concrete isn't just carbon-neutral, it's actively pulling carbon dioxide out of the surrounding air while being structurally stronger, not weaker, than what's currently used.

The researchers suggest it could be used in pavements, sewer pipelines, and walls, especially in areas with higher CO2 concentrations.

Most brain implants can only do one job at a time, either record activity, stimulate tissue, or deliver medication, and usually only at a single point. A new implant developed at the Technical University of Denmark, with University of Copenhagen and University College London, does all three at once.

Called the microfluidic Axialtrode, it's a needle-thin, flexible fiber less than half a millimeter wide, made from soft polymer instead of rigid silicon. Its angled tip and internal design let it deliver light-based stimulation, record electrical activity, and inject drugs at different depths along a single fiber, rather than just at the tip.

In mouse testing, the implant stimulated neurons with light, recorded activity from both surface and deep brain layers like the cortex and hippocampus, and delivered substances at depths nearly three millimeters apart, all through one lightweight fiber the animals wore without visible discomfort.

Because it's soft and flexible, it also appears to trigger less inflammation than rigid implants. The technology is currently aimed at basic brain research, but the team sees potential for future use in conditions like epilepsy.

Would multi-function implants like this speed up brain research?

Most plastic recycling barely makes a dent because the process is expensive and energy-hungry. Researchers at Oak Ridge National Laboratory may have found a cheaper way around that problem.

Their target is polyethylene, the plastic used in shopping bags and cutting boards, and one of the most common plastics in the waste stream. Normally, turning it back into fuel requires pyrolysis, heating it to 450–500°C to break the long molecular chains apart. That takes a lot of energy and cost.

The ORNL team found they could do the same job using a molten salt made with aluminum chloride, at temperatures below 200°C, roughly what a kitchen oven reaches. The charged aluminum atoms create acidic sites that snap the long plastic chains into shorter, fuel-sized molecules, with no precious metal catalysts, solvents, or added hydrogen needed. About 60% of the output came out gasoline-like.

There's still a hurdle: the molten salt is sensitive to moisture, which researchers are working to solve before this could scale up commercially. But it's a promising step toward making plastic waste genuinely valuable instead of just a problem to store.

What do you think, could this actually make a dent in plastic waste?

The Dead Sea Scrolls have puzzled scholars for decades over one specific detail: a strange 364-day calendar used by the Qumran sect, the desert community believed to have written or collected the scrolls. Was it ever actually used, or just a theoretical ideal?

A new study from Tel Aviv University, led by Prof. Eshbal Ratzon, argues the calendar was real and used in daily religious life, at least at first. Because 364 is divisible by seven, every year had exactly 52 weeks, meaning holidays always landed on the same weekday. For a community focused on divine order, that mattered deeply.

But the calendar had a built-in flaw: it was shorter than the true solar year, so it slowly drifted out of sync with the seasons, similar to a clock losing a minute a day. Ratzon suggests this drift, combined with shifting political relationships with the Hasmonean leadership, eventually pushed the sect to abandon the calendar in practice, even as it stayed important symbolically.

Nearly 20 scrolls found at Qumran deal with calendars and astronomy, showing just how central this topic was to the community.

Preservatives are in nearly everything packaged, from bread to frozen meals to canned goods. A large new study suggests some of them may come with a hidden cost to heart health.

Researchers followed more than 112,000 adults in France for close to eight years, tracking detailed dietary intake including specific food additives. People with the highest intake of non-antioxidant preservatives, the kind used to prevent mold and bacteria, had a 29% higher risk of developing high blood pressure and a 16% higher risk of cardiovascular disease. Those eating more antioxidant preservatives, used to stop food from browning, had a 22% higher risk of high blood pressure.

Out of 17 commonly consumed preservatives, eight were linked to higher hypertension risk, including sodium nitrite, potassium sorbate, and citric acid. One additive, ascorbic acid (vitamin C's food-additive form), was linked to cardiovascular disease specifically, though researchers note that doesn't mean dietary vitamin C is the problem.

This is observational research, so it can't prove these additives directly cause heart issues. But the researchers say it supports leaning toward fresh, minimally processed foods where possible.
