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.....»»
Study presents a taphonomic-forensic analysis of the skulls from the Sima de los Huesos site
Nohemi Sala, a researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has just published a paper in the journal The Anatomical Recordthat catalogs the modifications to the largest known collection of skulls and jaws.....»»
Capturing the many facets of evolvability
All life evolves: microorganisms can become resistant to drugs, viruses evade our vaccines, and species may adapt to climate change. Even the ability to evolve can evolve. If we were to understand how this happens and which mechanisms play a role, it.....»»
Microsoft destroys AltspaceVR community to focus on live events
Microsoft said that as platforms like AltspaceVR evolve, it’s important to look at existing experiences and evaluate whether they are properly serving the needs of customers today and in the future. Shielding users from inappropriate behavior and h.....»»
Plant smoke detectors evolve as hormone sensors
Wildfires are devastating, but they can also bring new life by clearing existing vegetation and allowing new plants to spring up. Many plants in fire-prone areas actually require exposure to fire for seeds to germinate. In the past decade, scientists.....»»
Primate proteins evolve to guard against pathogens, study finds
Proteins on the surface of cells act as sentries—and microbes hoping to invade will evolve tricks to evade these front-line defenses. But the host cell's proteins don't sit back helplessly. They, too, can evolve in ways that makes it harder for mic.....»»
The Gmail You Use for Work is Getting a Refresh Thanks to Chat and Meet
Google is continuing to evolve Gmail as we know it, especially for those who use it within a Workspace account, which used to be GSuite and is the version of Gmail used by work professionals. In a note posted yesterday, Google laid out upcoming plans.....»»
Myelin is a gift from retroviruses
A viable molecular explanation for the origin of compact myelin of vertebrates has been a long time coming. While many invertebrates are certainly capable of wrapping their axons with crude glial extensions, none can manage anything like the massive.....»»

Measuring medicine use in livestock supports the fight against antimicrobial resistance
Measuring how much antimicrobial medication is given to food animals is key to understanding how to slow antimicrobial resistance, when dangerous microbes get so used to antimicrobials that they evolve stronger defenses against them. However, measuri.....»»
New spheres of knowledge on the origin of life
The shape of a cell affects its physical and chemical properties. Different cell types have developed different shapes to enable effective functioning. But what shape were the very first cells, as life began to evolve?.....»»
How animals repurpose genes to develop both limbs, eyes
The last common ancestor of cephalopods and vertebrates existed more than 500 million years ago. In fact, a squid is more closely related to a clam than it is a to a person. Even so, the two lineages independently evolved camera-lens-style eyes with.....»»
A crowning achievement in understanding head development
Cranial neural crest cells, or CNCCs, contribute to many more body parts than their humble name suggests. These remarkable stem cells not only form most of the skull and facial skeleton in all vertebrates ranging from fish to humans, but also can gen.....»»
Researchers combine paleontology and fluid physics to uncover Ediacaran nurseries
Knowing how life worked on Earth 550 million years ago can give perspective on how life could evolve on other planets. And geobiologist and assistant professor of Earth and environmental sciences Simon Darroch and postdoctoral researcher Brandt Gibso.....»»
Our galaxy"s most recent major collision
One of the characteristic features of modern cosmology is its description of how galaxies evolve: via a hierarchical process of colliding and merging with other systems. Nowhere in the universe do we have a clearer view of this buildup than in our ow.....»»
Elon Musk reveals who bitcoin"s creator Satoshi Nakamoto might be
Musk.MARK RALSTON/AFP via Getty ImagesElon Musk seems to agree with many that hyper-secret cryptocurrency expert Nick Szabo could be Satoshi Nakamoto, the mysterious creator of the digital currency Bitcoin. "You can watch ideas evolve befo.....»»
Drunken solution to the chaotic three-body problem
The three-body problem is one of the oldest problems in physics: It concerns the motions of systems of three bodies—like the sun, Earth, and the moon—and how their orbits change and evolve due to their mutual gravity. The three-body problem has b.....»»
Your seat on public transportation determines level of exposure to exhaled droplets
The COVID-19 pandemic has revealed the urgency of understanding how public transportation ventilation systems transmit viruses and how exhaled droplets evolve in ventilated spaces. Researchers have wondered if those ventilation systems can be improve.....»»
Theropod dinosaur jaws became stronger as they evolved, study finds
Theropod dinosaurs evolved more robust jaws through time allowing them to consume tougher food, a new study reveals......»»
