Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South ...
Multicellular life depends on remarkable acts of cooperation. Every cell in the human body must sense what is happening around it, interpret signals from its neighbors and respond in ways that support the larger tissue. These ...
This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical ...
Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results ...
Mosses are survivors. They can dry into what looks like green dust, only to spring back to life minutes after rain. They can grow on rocks, in deserts, and there's talk of using them to terraform Mars someday. According to ...
Life on our planet began in the water. Eventually, one branch of the fish family tree developed legs and came up on land. These early four-legged animals, the tetrapods, were the forebears of today's mammals, birds, reptiles ...
An international study led by Curtin University has revealed new insights into how an ancient flying reptile was preserved in extraordinary detail for 113 million years, offering a rare glimpse into a vanished world.
In a strong El Niño winter, normally dry regions can suddenly drown in rain. NASA notes that "typically dry regions can experience nearly two times as much rain during a strong El Niño." Indeed, the blockbuster El Niños of ...
For more than a century, chemists have been building complex molecules step by step—bond by bond, atom by atom. But what if, instead of painstakingly reassembling molecules, they could be directly "rewritten"? This is exactly ...
Researchers have found evidence of a previously unknown branch of the marsupial family tree, a discovery that could reshape our understanding of how Australia's unique mammals evolved. Published in the Journal of Paleontology, ...
