Un estudio de modelización sugiere que los organismos especulares se enfrentarían a graves obstáculos para sobrevivir en entornos naturales. Otros investigadores sostienen que el análisis subestima los riesgos potenciales y la adaptabilidad evolutiva.

Investigadores dirigidos por Ricard Solé en el Instituto Santa Fe utilizaron modelos informáticos para explorar si la vida especular podría establecerse de forma autónoma en la Tierra. El estudio, publicado como preimpresión en bioRxiv con el DOI 10.64898/2026.05.07.723461, concluye que la falta de alimento con quiralidad especular adecuada dificultaría la supervivencia a largo plazo sin una infraestructura industrial dedicada.

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

23 de marzo de 2026 Reportado por IA

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

15 de abril de 2026 Reportado por IA

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.
