Scientists clash over threat of mirror life bacteria

Kiswahili

A modeling study suggests mirror organisms would face severe barriers to survival in natural environments. Other researchers argue the analysis underestimates potential risks and evolutionary adaptability.

Researchers led by Ricard Solé at the Santa Fe Institute used computer models to explore whether mirror life could establish itself autonomously on Earth. The study, posted as a preprint on bioRxiv with DOI 10.64898/2026.05.07.723461, concludes that a lack of suitable mirror-chiral food would make long-term survival difficult without dedicated industrial infrastructure.

Octopuses learn to use mirrors to locate hidden food

Researchers at Dartmouth have shown that octopuses can learn to use mirrors to find food they cannot see directly. The study, published in Current Biology, marks the first time this ability has been documented in invertebrates.

Researchers create 'zombie' cells from dead bacteria

Imeripotiwa na AI

Scientists have produced the first living synthetic bacterial cells by transplanting a synthetic genome into bacteria whose own genomes were destroyed. The team at the J. Craig Venter Institute calls these revived cells 'zombie cells'. The method addresses challenges in synthetic biology by ensuring control over the new genome.

Study uncovers squid survival during Earth's mass extinction

Researchers at the Okinawa Institute of Science and Technology have revealed how squid and cuttlefish survived the Cretaceous-Paleogene mass extinction by retreating to oxygen-rich deep-sea refuges. Their analysis of newly sequenced genomes shows these cephalopods originated in the deep ocean over 100 million years ago, followed by rapid diversification into shallow waters. The findings, published in Nature Ecology & Evolution, provide the first comprehensive evolutionary tree for decapodiform cephalopods.

Social bonds shape gut bacteria in Seychelles warbler birds

Imeripotiwa na AI

Researchers at the University of East Anglia have found that Seychelles warblers with closer social ties share more similar gut microbes, particularly anaerobic types spread through direct contact. The study on Cousin Island suggests social interactions drive this microbial exchange. Similar effects likely occur among humans living together.
