Horseshoe Crab Blood Powers Every Vaccine and Injection You Have Ever Been Given

The blue blood that guards every hospital on EarthHorseshoe crab blood is blue. Not metaphorically, literally blue, because it uses copper-based hemocyanin to carry oxygen instead of the iron-based hemoglobin that makes human blood red. But the colour is not why the biomedical industry harvests roughly 600,000 horseshoe crabs every…

Why does Salmonella cause serious illness in some people but not others?

For most people, a Salmonella infection causes gastroenteritis, an inflammation of the stomach and intestines that can mean several miserable days of diarrhoea, cramps, fever or vomiting. Most people recover within a week. But severe diarrhoea and dehydration can still be dangerous, even while the bacteria remain confined to the…

Every day, 50,000 litres of polluted water flow from South Africa's Stiebeuel River into natural filter beds, where stones, sand and biochar clean it in 5 days, removing 99% of harmful bacteria and creating water for irrigation

Researchers in South Africa are using a nature-based filtration system to treat polluted water from the Stiebeuel River in Franschhoek. At the Water Hub, old wastewater treatment infrastructure has been adapted with stones, coarse sand, biochar, plants and naturally occurring microbes to remove pollutants. The system treats approximately 50,000 litres…

In 15 days, Cornell-engineered bacterium broke down olivine and extracted 75% of its magnesium, while releasing nickel and cobalt and forming a carbon-storing mineral that could link mine waste to cleaner batteries

A Cornell-engineered bacterium rapidly weathers olivine, extracting magnesium and releasing critical metals. This process also forms a carbon-bearing mineral, offering dual benefits. The bacteria accelerate a natural weathering process, enhancing mineral dissolution significantly. This discovery could combine carbon storage with valuable metal recovery for batteries.

It's harder to poop in space. Scientists may finally know why

Spaceflight can do strange things to the human body — including making it harder for astronauts to poop.

52 astronauts left Earth for months in orbit, and within weeks their gut bacteria changed how they processed food, revealing why spaceflight can trigger constipation and potentially affect brain health

Constipation in space is more than an uncomfortable side effect. Astronauts often face it during long missions, but scientists have not fully understood why. Now, blood tests from 52 astronauts reveal a possible clue. Their gut bacteria began fermenting more protein within weeks of reaching the International Space Station. The…

From gut bacteria to the brain, a chemical, sodium butyrate traveled through the bloodstream after traumatic injury, where 4 months of treatment helped scientists reduce inflammation, protect brain cells and made seizures less frequent

Post-traumatic epilepsy treatment: Researchers are exploring sodium butyrate to prevent post-traumatic epilepsy after brain injuries. This gut-produced chemical reduces brain inflammation and promotes cell survival. Four months of treatment showed fewer and less intense seizures in animal studies.

In 130 days, deep beneath the Ore Mountains bacteria turned uranium-contaminated mine water into a chemical trap, removing 95% of the dissolved metal and forming a rare compound that can remain stable for decades

Deep underground, bacteria may offer a new answer to uranium contamination. In a 130-day laboratory experiment, microbes fed with glycerol removed about 95% of dissolved uranium from contaminated mine water. The bacteria did more than trap the radioactive metal. They helped form FeU(V)O₄, a rare and unusually stable uranium compound.…
