BERKELEY, Calif.--All per- and polyfluorinated substances (PFAS) should be treated as one class and avoided for nonessential uses, according to a peer-reviewed article published today in Environmental Science & Technology Letters.
The team was co-led by May Griffith, a researcher at Maisonneuve-Rosemont Hospital Research Centre, which is affiliated with Université de Montréal and is part of the CIUSSS de l'Est-de-l'Île-de-Montréal.
The results of this multinational project have just been published in the journal Science Advances.
"Our work has led to an effective and accessible solution called LiQD Cornea to treat corneal perforations without the need for transplantation," said Griffith. She is also a full professor in the Department of Ophthalmology at Université de Montréal.
Micro - nano Optics and Technology Research Group led by Prof. LU Yonghua and Prof. WANG Pei from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) realized nanometric displacement measurement through the interaction between the illumination optical field and the optical antennas. This study was published on Physical Review Letters.
A team led by Prof. NI Yong and Prof. HE Linghui from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) designed a discontinuous fibrous Bouligand (DFB) architecture, a combination of Bouligand and nacreous staggered structures. Systematic bending experiments for 3D-printed single-edge notched specimens with such architecture indicated that total energy dissipations are insensitive to initial crack orientations and show optimized values at critical pitch angles. The study was published in PNAS on June 22.
A collaborative research team from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) and China Geological Survey (CGS) have succeeded in obtaining a high-resolution 3D resistivity model of approximately 20 km depth beneath the Weishan volcano in the Wudalianchi volcanic field (WVF) for the first time. The study, published in Geology, revealed the image of potential magma chambers and the estimated melt fractions.
As the COVID-19 pandemic spreads around the world, masks have become an essential personal hygiene product as the first line of defense to protect one's respiratory system against the viruses and germs that spread through droplets in the air. It's a waste to dispose the masks after single use but troubling to reuse them. In light of this, a Korea-Japan research team recently released findings that compare and analyze the performance and functional differences of the filters used in masks after they are cleaned with ethanol.
Artificial intelligence (AI) improved skin cancer diagnostic accuracy when used in collaboration with human clinical checks, an international study including University of Queensland researchers has found.
The global team tested for the first time whether a 'real world', collaborative approach involving clinicians assisted by AI improved the accuracy of skin cancer clinical decision making.
A new study illustrates the potential impact of recurrent heatwaves on coral species collected by the Australian aquarium coral industry.
The study's lead author, Professor Morgan Pratchett from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU), says there are active and expanding aquarium coral fisheries operating across the country in Western Australia, the Northern Territory and Queensland.
Before a drug can be used to treat patients, it goes through several rounds of testing for efficacy and toxicity, which begin in animal models. Zebrafish, a tiny species of fish native to South Asia, are cheaper to maintain and easier to breed than laboratory mice or other animal models. They also share many disease-related genes with us, particularly those involved in neurological disorders. This makes them a great model for drug development.
TALLAHASSEE, Fla. -- Thank goodness for the Earth's crust: It is, after all, that solid, outermost layer of our planet that supports everything above it.
But much of what happens below that layer remains a mystery, including the fate of sections of crust that vanish back into the Earth. Now, a team of geochemists based at the Florida State University-headquartered National High Magnetic Field Laboratory has uncovered key clues about where those rocks have been hiding.
Workplace gender bias is being kept alive by people who think it's no longer an issue, new research suggests.
In the study, managers were given identical descriptions of a worker - the only difference being either a male or female name.
Most managers rated the male worker as more competent, and recommended a higher salary - an average 8% pay gap.
The "key drivers" of this gap were managers who thought bias no longer existed in their profession, while those who believed bias still existed recommended roughly equal pay.
Fires have spread across the majority of the landscape in Angola and the Democratic Republic of the Congo in this NOAA/NASA Suomi NPP satellite image using the VIIRS (Visible Infrared Imaging Radiometer Suite) instrument from June 25, 2020. Fires of this number are not uncommon at this time of year in Africa. During the agricultural season of clearing field and planting new ones, farmers set fire to the remains of old crop fields to rid them of the leftover grasses and scrub. This action also helps return nutrients to the soil to ensure a good crop during the next planting season.
CAMBRIDGE, MA -- When neurons fire an electrical impulse, they also experience a surge of calcium ions. By measuring those surges, researchers can indirectly monitor neuron activity, helping them to study the role of individual neurons in many different brain functions.
The brain analyses spoken language by recognising syllables. Scientists from the University of Geneva (UNIGE) and the Evolving Language National Centre for Competence in Research (NCCR) have designed a computational model that reproduces the complex mechanism employed by the central nervous system to perform this operation. The model, which brings together two independent theoretical frameworks, uses the equivalent of neuronal oscillations produced by brain activity to process the continuous sound flow of connected speech.
A new function-based sequencing technique using optical tweezers and taking advantage of the properties of gravity is letting researchers analyze bacteria cells one by one. The study, conducted by researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, was published in Small on June 9.
