New viable means of storing information for quantum technologies?

Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit and using it remains complex, and hence limited. In a study published on 3 August 2021 in Physical Review X, an international research team consisting of CNRS...

Volcanic tremor and deformation at Kīlauea

Kīlauea in Hawaii is the best-monitored volcano in the world. The 2018 eruption was the largest in some 200 years, providing researchers with a plethora of new data to understand the volcano's plumbing and behavior. Two new studies dig into data on volcanic tremor and deformation to better characterize the events leading up to and following the 2018 eruption.

Developing Tiny Micro-Shutter Arrays to Answer Big Questions

PROJECT NexGen Micro-Shutter Array (NGMSA) SNAPSHOT Advanced technology micro-shutters enable NASA to study galaxy evolution across cosmic time. Goddard Space Flight Center astrophysicist Matt Greenhouse and lead engineer Mary Li examine a NexGen array prototype containing 282,624 programmable micro-shutters. How did the first stars and galaxies form after the big bang? How did they...

Appearance of cystic fibrosis at the molecular scale

Despite remarkable medical advances over the last years, cystic fibrosis remains the most prevalent lethal genetic disease. It is due to mutations in the CFTR protein which is normally required to maintain proper fluid balances in key organs such as lungs, pancreas or the digestive system.

How the pandemic has impacted environmental field research

Field stations and marine laboratories (FSMLs) serve as great drivers of research, monitoring, and learning about our world. However, FSMLs across the globe are facing major cutbacks and even closure due to COVID-19 pandemic-driven budget cuts. UConn's Gene E. Likens and David L. Wagner, professors in the Department of Ecology and Evolutionary Biology, have written an editorial in Science...

Scientists discover 'bulkheads' between liver cells

Researchers from Skoltech and their colleagues from Germany and the U.S. have discovered structures responsible for the shape of bile canaliculi, a network of canals in the liver. Published in the Journal of Cell Biology, their study also reveals the gene essential for the formation of these structures, which the team compares to boat bulkheads.

Measuring nitrogen in green manures

Both chemical fertilizers and cover crops can help build the nitrogen content in soil. But cover crops come with many other benefits, like improving soil structure and boosting beneficial microbes.

New viable means of storing information for quantum technologies?

Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit and using it remains complex, and hence limited. An international research team used theoretical calculations to show that it is possible to realize a new...

Particles from paints, pesticides can have deadly impact

Hundreds of thousands of people around the world die too soon every year because of exposure to air pollution caused by our daily use of chemical products and fuels, including paints, pesticides, charcoal and gases from vehicle tailpipes, according to a new CU Boulder-led study.

Giraffe grandmothers are high-value family members, say scientists

As with elephants and orcas, worldly wisdom and childcare brings group-survival perks, research suggestsPillars of family life, the community and often the workplace, grandmothers are a crucial component of human society – now researchers say they may also play an important role among giraffes.Experts conducting a review of giraffe social behaviour say female giraffes live for about eight years...
