China to release updated climate plans 'in near future': envoy
China's climate envoy on Tuesday said the world's most populous nation would release its updated plans to reduce carbon emissions "in the near future" as nations prepare to meet later this year for a pivotal global conference.
Molecular dance that could eliminate soot pollution
A hidden, newly discovered molecular dance could hold the answer to the problem of soot pollution.
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.

Iraq gets back looted ancient artifacts from US, others
Over 17,000 looted ancient artefacts recovered from the United States and other countries were handed over to Iraq's Culture Ministry on Tuesday, a restitution described by the government as the largest in the country's history.
Making voting easier for previously incarcerated people
In March 2020, 83,000 New Jersey residents who had been ineligible to vote became eligible when a new law took effect restoring voting rights for people on parole or probation who had previously been convicted of felonies.
NASA satellites help plan future for Palau fish stocks
It's the weekend, and freshly caught fish sizzles on the grill. The view: an unforgettable beach and the cobalt blues of the Pacific Ocean in the backdrop.
NASA begins launch preparations for first mission to the Trojan asteroids
NASA's first spacecraft to explore the Trojan asteroids arrived Friday, July 30, at the agency's Kennedy Space Center (KSC) in Florida. It is now in a cleanroom at nearby Astrotech, ready to begin final preparations for its October launch.
Photoirradiation-based super-resolution gene analysis technology developed
A Japanese research group developed a technology termed Photo-Isolation Chemistry (PIC) and successfully detected genes acting in very small cell populations and in intracellular microstructures by photoirradiation.
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.
Researchers are first in the world to watch plants 'drink' water in real-time
The inability to monitor water uptake inside roots—without damaging the specimen—has been a key stumbling block for researchers seeking to understand the motion of fluids in living plant cells and tissues.
Skull of 340 million year old animal digitally recreated, revealing secrets of ancient amphibian
Researchers from the University of Bristol and University College London have used cutting-edge techniques to digitally reconstruct the skull of one of the earliest limbed animals.
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.
Education professor outlines measures for meaningful education reform post-COVID
With Ontario elementary and secondary schools looking at a full return to in-person learning this September, the burden of keeping them open should not just fall on the school boards, according to global education expert Prachi Srivastava.
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.
