A beautifully preserved fossil from Mongolia's Gobi Desert has solved a mystery that puzzled paleontologists for nearly 40 years. Tamirkhan balcarceli shows that zhelestids were not early relatives of modern placental mammals, despite having teeth .. ...

Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for ...

Scientists have streamlined a method for measuring DNA-bound phosphorus in soil, making it cheaper and easier while preserving its accuracy. The technique could reveal how soil microbes help recycle phosphorus and ultimately support more sustainable ...

Scientists studying ancient Australian rocks uncovered more than 12,000 fossils from some of the oldest known eukaryotes on Earth. These early complex cells lived in settings ranging from coastal mudflats to the open sea, but only where oxygen was .. ...

Ancient DNA shows that adults and children buried together in medieval Sweden were often not members of the same immediate family, suggesting that burial choices reflected more than biological kinship. The research also revealed early gender-based .. ...

Scientists have mapped the genetics of cat cancer on an unprecedented scale and found surprising similarities with tumors in humans. The findings could help bring precision cancer treatments to cats while also revealing new clues about how human ...

Scientists have found that a famous 2-billion-year-old chemical signature, once thought to record a massive global change in Earth's carbon cycle, may instead have been produced by local magma, hydrocarbons, and methane-eating microbes. The discovery ...

Scientists discovered that tiny amounts of lead in ancient ink can make writing inside burned papyrus scrolls stand out dramatically in X-ray scans. The technique could help unlock lost Greek and Roman texts preserved by the eruption of Mount ...

Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self ...

Scientists discovered rare flavoalkaloids in Cannabis leaves for the first time, along with dozens of other phenolic compounds that had never been reported in the plant. The findings suggest that Cannabis leaves, often discarded as waste, may contain ...
