Specific bacteria in the gut prompt mother mice to neglect their pups
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:...
Dewdrops on a spiderweb reveal the physics behind cell structures
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.
Turning on the switch for plasticity in the human brain
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...

‘Immunological unicorn’: the Australian lab growing coronavirus – and its startling discovery
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.
Islands without structure inside metal alloys could lead to tougher materials
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...
Accurate drug dosages with proton traps
An international team of researchers produced islands of amorphous, non-crystalline material inside a class of new metal alloys known as high-entropy alloys.
Genes that dance to the circadian rhythm
Researchers at Linköping University, Sweden, have developed a proton trap that makes organic electronic ion pumps more precise when delivering drugs. The new technique may reduce drug side effects, and in the long term, ion pumps may help patients with symptoms of neurological diseases for which effective treatments are not available. The results have been published in Science Advances.
Lewis Wolpert obituary
Scientists at EPFL have made breakthrough discoveries on the circadian clock and how it affects gene expression. Some of the findings suggest a biological underpinning for different behaviors in people, such as morning people, nappers, evening people, night owls etc.
By changing their shape, some bacteria can grow more resilient to antibiotics
Developmental biologist and science communicator with an enduring fascination for the beginnings of lifeHow does a single fertilised egg divide and morph into an embryo with head, tail, limbs and organs? That question was an inexhaustible source of fascination to the biologist Lewis Wolpert, who has died aged 91. With a twinkle in his eye, he told audiences it was not birth, marriage or death, but...
Oxford/AstraZeneca Covid vaccine given full approval by EU regulator
New research led by Carnegie Mellon University Assistant Professor of Physics Shiladitya Banerjee demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape. The work was published in the journal Nature Physics.
Startup develops yeast-based COVID-19 diagnostic test
European Medicines Agency approves jab for use in all age groups above 18, despite German doubtsCoronavirus – latest updatesSee all our coronavirus coverageThe European Medicines Agency has authorised the Oxford/AstraZeneca Covid-19 vaccine for use in all adult age groups after days of doubt.A month after it received approval in the UK, the EU’s regulator declared the vaccine safe for general...
Scientists look to soils to learn how forests affect air quality, climate change
Incubated at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and supported by São Paulo Research Foundation- FAPESP's Innovative Research in Small Business Program (PIPE), BIOinFOOD is a startup that is developing a rapid COVID-19 diagnostic test based on a patent application filed by students at UNICAMP's Genomics and Bioenergy Laboratory.
UK vaccine strategy 'paying off' as latest trials boost stockpiles
Trees are often heralded as the heroes of environmental mitigation. They remove carbon dioxide from the atmosphere, which slows the pace of climate change, and sequester nutrients such as nitrogen, which improves water and air quality.

New study investigates photonics for artificial intelligence and neuromorphic computing
Nearly nine out of 10 Americans say they enjoy sports at least a little, but heterosexual men more commonly identify as passionate sports fans, a new study suggests.
How is human behavior impacting wildlife movement?
Scientists have given a fascinating new insight into the next steps to develop fast, energy-efficient, future computing systems that use light instead of electrons to process and store information—incorporating hardware inspired directly by the functioning of the human brain.
Coiling them up: Synthesizing organic molecules with a long helical structure
For species to survive in the wild, maintaining connectivity between populations is critical. Without 'wildlife corridors,' groups of animals are isolated, unable to breed and may die out. In assessing wildlife connectivity, many aspects of the landscape are measured, but the impact of human behavior has largely been overlooked. Now, an international team led by the University of Göttingen and...
Scientists at Tokyo Institute of Technology (Tokyo Tech) produced and extensively characterized novel organic molecules with a long helical structure. Unlike previous helical molecules, these longer compounds exhibit special interactions between coils that could give rise to interesting optical and chemical properties with applications in light polarization, catalysis, and molecular springs.
