Citizen Scientists Help Create 3D Map of Cosmic Neighborhood
Is our solar system located in a typical Milky Way neighborhood? Scientists have gotten closer to answering this question, thanks to the NASA-funded Backyard Worlds: Planet 9 project, a “citizen science” collaboration between professional scientists and members of the public. Scientists tapped into the worldwide network of 150,000 volunteers using Backyard Worlds:...
Specific bacteria in the gut prompt mother mice to neglect their pups
As scientists learn more about the microorganisms that colonize the body—collectively called the microbiota—one area of intense interest is the effect that these microbes can have on the brain. A new study led by Salk Institute scientists has identified a strain of E. coli bacteria that, when living in the guts of female mice, causes them to neglect their offspring.
Dewdrops on a spiderweb reveal the physics behind cell structures
As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that governs the mixing of liquids is not limited to mixing bowls; it...
Turning on the switch for plasticity in the human brain

Scientists describe how glutamate signals are transmitted across synapses to turn on the switch for synapatic plasticity, the ability of synapses to strengthen or weaken over time in response to increases or decreases in their activity.
‘Immunological unicorn’: the Australian lab growing coronavirus – and its startling discovery
Researchers walk through three negative-pressure chambers before entering the submarine-like structureIn a high security laboratory in Sydney, where a select group of researchers go to extreme lengths to work with samples of blood and swabs containing Covid-19, virologist Stuart Turville found a unicorn.“A beautiful, immunological unicorn,” Turville, an associate professor with the Kirby...
Islands without structure inside metal alloys could lead to tougher materials
An international team of researchers produced islands of amorphous, non-crystalline material inside a class of new metal alloys known as high-entropy alloys.
