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.....»»
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.....»»
Bizarre ancient sea creature brings evolution mystery to the surface
A new tunicate fossil, a close relative of vertebrates, is half a billion years old. Enlarge / That blue tube is actually a very close relative of vertebrates. (credit: Gerard Soury) Beneath the waves, there are strange,.....»»
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
A recent study led by Dr. Itamar Harel from the Silberman Institute at the Hebrew University of Jerusalem has revealed new insights into the role of AMP biosynthesis in the lifespan and metabolic health of vertebrates......»»

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......»»
Facial tumors evolve to coexist with Tasmanian devil populations, shows new study
Research led by the University of Tasmania has found that the deadly devil facial tumor disease (DFTD) responsible for wiping out two-thirds of the species over the last 30 years is evolving to coexist with devil populations......»»
Climate change could lead to "widespread chaos" for insect communities
New species continue to evolve the world over, as different groups of organisms separate and take divergent paths. What happens when you add climate change to the mix?.....»»
The world"s fish are shrinking as the climate warms. Researchers are trying to figure out why
Fish are the most diverse group of vertebrates, ranging from tiny gobies and zebrafish to gigantic tunas and whale sharks. They provide vital sustenance to billions of people worldwide via fisheries and aquaculture, and are critical parts of aquatic.....»»
China"s Yanliao Biota offers a new window into mammal evolution since the Triassic
China's Yanliao Biota, an assembly of fossils preserved in northeastern China dating from the Middle to Late Jurassic (174 to 145 million years ago), offers an important window into the evolution of vertebrates. With exceptional preservation of insec.....»»
Researchers develop universal MHC molecules that can be produced rapidly at scale
Class I major histocompatibility complex (MHC-I) proteins play an essential role in the immune system of all jawed vertebrates. The MHC-I displays peptide fragments of proteins from within the cell on the cell surface, "presenting" them to the immune.....»»
Sonic Superstars found great new ways to freshen up the classic 2D formula
