Ultrasensitive gas detection empowered by synergy of graphene and sub-comb dynamics
Since the inception of microcomb, whose generation relies on Kerr nonlinearity in microresonator, the coherent soliton state has attracted intense research. Although the operation of sub-comb outputs is straightforward, as a noncoherent comb state,.....»»
Chemists develop graphene-based biosensor, paving the way for advanced diagnostics
Two-dimensional materials such as graphene are not only ultrathin, but also extremely sensitive. Researchers have therefore been trying for years to develop highly sensitive biosensors that utilize their properties......»»
The melting of Greenland: A climate challenge with major implications for the 21st century
The melting of Greenland is accelerating, with an estimated loss of between 964 and 1735 gigatons of ice per year by 2100 in a scenario of high greenhouse gas emissions (SSP585), according to three regional climate models. This melting will lead to a.....»»
Fossil fuel supply: The elephant in the room at climate change conferences
"Natural resources … are a gift from God. Every natural resource, whether it's oil, gas, wind, sun, gold, silver, copper, they are all natural resources. Countries should not be blamed for having them, and should not be blamed for bringing these re.....»»
Colorado investigates reports of falsified data on cleanup of about 350 oil, gas sites
State oil and gas regulators are investigating reports that environmental consultants falsified results of tests on soil, groundwater and contamination at about 350 locations in Weld County between 2021 and this summer......»»
Is there enough land on Earth to fight climate change and feed the world?
Capping global warming at 1.5°C is a tall order. Achieving that goal will not only require a massive reduction in greenhouse gas emissions from human activities, but also a substantial reallocation of land to support that effort and sustain the bios.....»»
China experiences reduction in food system inequality and carbon footprint alongside economic development
Humans have persistent food needs that trigger considerable greenhouse gas emissions, varying significantly by region. However, the greenhouse gas (GHG) footprint and inequality in the food system are not well assessed within countries......»»
Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the lowest mass ratio contact bi.....»»
New transformer-based AI model enhances precision in rice leaf disease detection
Rice is one of the world's most essential food crops, but its production is constantly threatened by leaf diseases caused by pathogens such as fungi, bacteria, and viruses. These diseases, which manifest as spots or blotches on leaves, can severely i.....»»
Petrol industry embraces plastics while navigating energy shift
Amid the inexorable shift toward more electric vehicles, oil and gas producers are looking increasingly to plastics to help keep them afloat, even if that sector faces challenges of its own......»»
Scientists seek miracle pill to stop methane cow burps
A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas......»»
In Patagonia, more snow could protect glaciers from melt—but only if greenhouse gas are curbed emissions soon
In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study in Scientific Reports from INSTAAR postdoc Matthias Troch suggests that this protective effect might be pushed up against i.....»»
Nano-patterned copper oxide sensor provides rapid ultra-low hydrogen detection
Hydrogen is becoming an increasingly popular choice as we shift towards cleaner energy. It can be burned like traditional fuels, producing only water as a byproduct, and can generate electricity when used in fuel cells. However, as hydrogen productio.....»»
Veil of fiery gas revealed around the disk of Milky Way
Scientists may have finally hit upon the possible mysterious sources that have pumped heat and kept alive the fiery hot gas that has recently been detected surrounding the Milky Way but has so far remained unexplained......»»
Using gas bubbles to precisely deliver nanomedicines shows promise for lung cancer treatment
The delivery of nanomedicines using gas bubbles has shown itself to be a unique way of transporting cytotoxins to the lungs of cancer patients. The method enables precise and focused treatments, and the local action of the drugs also prevents a range.....»»
Support for carbon pricing higher than expected, finds study
Viewed by many experts as one of the most effective tools of climate policy, carbon pricing seeks to reduce carbon dioxide emissions. Currently, however, only 23% of global greenhouse gas emissions are subject to this climate tax, as it is seen as un.....»»
Geospatial mapping study shows drought trend in ag-dominated Arkansas Delta
The Delta, a regional powerhouse for Arkansas agriculture built by river flows, is showing a trend of increasing droughts. Using satellite imagery, Arkansas Agricultural Experiment Station researchers comprehensively analyzed drought dynamics over fi.....»»
Scientists uncover cross-species neural mechanism for early detection of life motion in visual processing
Visual systems of both humans and animals can detect life motion from the environment at the earliest stage of visual processing, research by scientists from the Chinese Academy of Sciences (CAS) uncovered......»»
AI-assisted sorting system automates detection of aluminum-tolerant microbes in acidic soils
Researchers from the Single-Cell Center at the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences, together with collaborators, developed an artificial intelligence-assisted Raman-activated cell sorting (AI-RA.....»»
