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,.....»»
Airborne microplastics aid in cloud formation
It turns out microplastics have an effect on the weather and climate. Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such.....»»
Quasiperiodicity changes the ground-state properties of 1D narrow-band moiré systems, study demonstrates
Moiré materials, such as twisted bilayer graphene, are materials generally formed by stacking two or more layers of 2D materials on top of each other with a small lattice mismatch. This slight mismatch creates a unique pattern known as the moiré pa.....»»

Team develops non-invasive biosensor for early kidney disease detection
Traditionally, kidney health has been monitored by measuring blood creatinine levels, which indicate muscle breakdown. High creatinine levels can suggest that the kidneys are not filtering waste efficiently. However, creatinine levels can be affected.....»»
Public pressure found to influence whether companies reduce their environmental impact
The effectiveness of national voluntary programs asking companies to pledge to lower their pollution and greenhouse gas emissions depends on pressure from the public, according to a new study led by a Penn State researcher......»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
Ultrasensitive nanoscale sensors can identify lung cancer through exhaled isoprene
Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses—and improve patients' prospects. In a study in ACS.....»»
New research may lead to potatoes that are less reliant on nitrogen fertilizers
Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that bloc.....»»

Bach, Mozart or jazz: Scientists provide a quantitative measure of variability in music pieces
Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of dif.....»»
Water overuse in Brazil"s MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead......»»
School burnout can be prevented with the right measures, but students" challenges must be acknowledged
School burnout can manifest in students in different ways. Some might feel tired or anxious, while in others, burnout may manifest as a negative attitude towards school. Early detection of the various signs and symptoms of burnout is important, as it.....»»
Study identifies promising materials for fusion reactors
Nuclear fusion could be an ideal solution to mankind's energy problem, guaranteeing a virtually limitless source of power without greenhouse gas emissions. But there are still huge technological challenges to overcome before getting there, and some o.....»»
