Even though we are led to believe that during the Cretaceous the Earth used to be an exclusive home for fearsome giants, including carnivorous velociraptors and arthropods larger than a modern adult human, it turns out that there...
Most of the fauna in the Arctic region take part in pollinating, yet during the busiest flowering weeks, there's a shortage of such services. A recent study indicates that the pollination services provided to plants and, thus, the...
More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice -- ice that was...
A University of Kansas geologist's work in the remote High Arctic of Norway has exposed the startling global spread of antibiotic-resistant microbes -- including multidrug-resistant "superbugs" -- that could have dire implications for human health worldwide. Jennifer Roberts, professor...
Two humongous asteroids, each capable of annihilating an entire city, are approaching our planet, NASA reported. The agency’s Centre for Near-Earth Objects, tasked with monitoring celestial objects that may pose a danger to the Earth, reported that the two...
For decades, scientists have searched for effective ways to remove excess carbon dioxide emissions from the air, and recycle them into products such as renewable fuels. But the process of converting carbon dioxide into useful chemicals is tedious,...
An enzyme-blocking molecule can extend the lifespan of Caenorhabditis elegans roundworms by as much as 45 percent, largely by modulating a cannabinoid biological pathway, according to a study from scientists at Scripps Research. The scientists, whose work is published...
Water fleas of the genus Daphnia detect via chemical substances if their predators, namely Chaoborus larvae, are hunting in their vicinity. If so, they generate defences that make them more difficult to consume. The signalling molecules that enable...
Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers at Uppsala University have, for the first time, sequenced (or...
In a study with significant implications for human organ transplantation, researchers have successfully grown functional mouse kidneys inside rats from just a few donor stem cells. The results of the study, led by researchers from the National Institute for...
