How did vertebrates first evolve jaws?
Five-hundred million years ago, it was relatively safe to go back in the water. That's because creatures of the deep had not yet evolved jaws. In a new pair of studies in eLife and Development, scientists reveal clues about the origin of this thrilli.....»»

Surprise COVID discovery helps explain how coronaviruses jump species
Unexpected new insights into how COVID-19 infects cells may help explain why coronaviruses are so good at jumping from species to species and will help scientists better predict how COVID-19 will evolve......»»
Scientists discover how parasites of viruses drive superbug evolution
In a study published in Cell, scientists from the National University of Singapore (NUS) and Imperial College London have discovered a new way by which bacteria transmit their genes, enabling them to evolve much faster than previously understood......»»
DNA decodes the dining preferences of the shell-shucking whitespotted eagle ray
With mighty jaws and plate-like teeth, the whitespotted eagle ray (Aetobatus narinari) can pretty much crunch on anything. In fact, hard clam farmers in Florida's Indian River Lagoon have considered this species a threat to their production efforts a.....»»

Competition for food? Jaw analyses show what cave bears and brown bears ate
The differences are in the details: Special 3D shape analyses of the jaws and dentitions of cave bears and brown bears living at the same time from the fossil site in the caves of Goyet in Belgium show their clearly different food spectrum......»»
Dark energy camera captures galaxies in lopsided tug of war, a prelude to merger
Galaxies grow and evolve over billions of years by absorbing nearby companions and merging with other galaxies. The early stages of this galactic growth process are showcased in a new image taken with the US Department of Energy's (DOE) Dark Energy C.....»»
Galaxy mergers shed light on galactic evolution model
An Australian astronomer has solved a century-old mystery regarding how galaxies evolve from one type to another. The same study shows that the Milky Way, the galaxy we live in, was not always a spiral......»»
New research suggests ways to improve underpass design for freshwater turtles
Freshwater turtles are among the most threatened groups of vertebrates globally and in the modern world of highly urbanized wetlands, they fight a constant battle for survival once they leave the safety of their aquatic home to nest on land......»»
Dolphins and Whales Will Never Evolve Back into Land Animals
Scientists have discovered that once mammals, such as dolphins or orcas, have become fully aquatic, they pass a threshold that makes a return to terrestrial landscapes almost impossible.....»»
Phylogenetic analysis suggests fully aquatic mammals are unlikely to evolve back into terrestrial creatures
A trio of biologists and environmental scientists, two with the University of Fribourg and the third with the Swiss Institute of Bioinformatics, has found that fully aquatic mammals, such as whales and porpoises, are very unlikely to evolve back into.....»»
Astronomers discover striking evidence of "unusual" stellar evolution
Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve......»»
How fish evolved their bony, scaly armor
About 350 million years ago, your evolutionary ancestors—and the ancestors of all modern vertebrates—were merely soft-bodied animals living in the oceans. In order to survive and evolve to become what we are today, these animals needed to gain so.....»»
"Evolving" and 3D printing new nanoscale optical devices
A new technology being pioneered at Caltech is allowing researchers to "evolve" optical devices and then print them out using a specialized type of 3D printer. These devices are made of so-called optical metamaterials that derive their properties fro.....»»

Dynamical dark energy might explain strange 21-cm signal
Dark energy may evolve in time, and it may even connect through a new force of nature with dark matter. A researcher believes that we may have already seen evidence for this. Their findings have been reported on the preprint server arXiv......»»
AMP biosynthesis key to longevity and metabolic health in vertebrates, study finds

Pace off: NASA Goddard acoustics chamber and US marine band turn up the volume
With a light flick of the conductor's baton and a unified breath from each member, the band started playing the two deep and ominous notes easily recognized as the theme of "Jaws." The sounds echoed off the walls of the acoustics chamber at NASA's Go.....»»
A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
From the 20-foot-long jawbones of the filter-feeding blue whale to the short, but bone-crushing, jaws of the hyena and the delicate chin bones of a human, the pair of lower jawbones characteristic of mammals have evolved with amazing variation......»»
