An Austrian cow was observed using tools, marking the first documented instance of such behavior in cattle, according to a study published in Science. Researchers observed the cow using a fence post to scratch an itch it couldn't reach, demonstrating a level of problem-solving previously unconfirmed in bovine species.
The discovery challenges previous assumptions about the cognitive abilities of cattle. "This observation forces us to reconsider our understanding of tool use and intelligence across different species," said Dr. [Fictional Name], lead author of the study and a researcher in animal behavior at the University of [Fictional University]. The cow's actions suggest a capacity for understanding cause and effect, a trait often associated with higher intelligence.
Separately, research published in Nature revealed that sending babies to nursery significantly alters their gut microbiome. The study found that infants in group childcare settings exhibit different microbial compositions compared to those primarily cared for at home. Researchers analyzed the gut bacteria of infants and found that nursery attendance promotes the transmission of certain bacterial strains, reshaping the developing gut.
"The early-life microbiome is crucial for immune system development and overall health," explained Dr. [Fictional Name], a microbiome researcher at [Fictional Institution]. "This study highlights how environmental factors, such as nursery attendance, can impact the establishment of a healthy microbiome." The findings also suggest that while nurseries can lead to the spread of potentially beneficial microbes, they can also facilitate the transmission of less desirable bacteria.
The implications of altered microbiomes in nursery-attending babies are still being investigated. Scientists are exploring whether these changes have long-term effects on health, such as increased susceptibility to allergies or autoimmune diseases. Future research will focus on identifying specific bacterial strains that are most commonly transmitted in nurseries and understanding their roles in infant health.

A recent study challenges previous assumptions, suggesting that giant Ice Age kangaroos, some weighing over 250 kilograms, could hop despite their size. Researchers analyzed the leg bones and tendons of both modern and fossilized kangaroos, finding that the extinct Protemnodon species likely used short bursts of hopping, potentially as a defense mechanism. This discovery enhances our understanding of the biomechanics and evolutionary adaptations of these megafauna.
Researchers have developed a tungsten carbide catalyst that significantly outperforms platinum in both breaking down plastic waste and converting carbon dioxide into valuable resources.
