A Möbius strip constructed solely of carbon atoms
Obtaining structurally uniform nanocarbons in order to properly relate structure and function, ideally as single molecules, is a great challenge in the field of nanocarbon science. Thus, the construction of structurally uniform nanocarbons is crucial.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Thermal properties of new 2D materials for microchips can now be measured well
Making ever smaller and more powerful chips requires new ultrathin materials: 2D materials that are only 1 atom thick, or even just a couple of atoms. Think about graphene or ultra-thin silicon membrane for instance......»»
Apple touts halving emissions and increased recycling rates in 2024 environmental progress report
Apple has an ambitious goal to create a fully carbon neutral value chain for its products by 2030, and every year it charts its progress in its annual Environmental Progress Report. The 2024 report published today highlights a milestone achievement f.....»»
The Rise of the Carbon Farmer
Farmers around the world are reigniting the less intensive agricultural practices of yesteryear—to improve soil health, raise yields, and trap carbon in the atmosphere back down in the soil......»»
Cheap ransomware for sale on dark web marketplaces is changing the way hackers operate
Since June 2023, Sophos X-Ops has discovered 19 junk gun ransomware variants — cheap, independently produced, and crudely constructed — on the dark web. The developers of these junk gun variants are attempting to disrupt the traditional affiliate.....»»
Soil bacteria link their life strategies to soil conditions: Study
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not f.....»»
Unique field study shows how climate change affects fire-impacted forests
During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team led from Lund University in Sweden has investigated how climate change affects recently burned boreal forests and their ability to absorb carbon dioxide......»»
Understanding climate warming impacts on carbon release from the tundra
The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into carbon sources, exacerbating the effects.....»»
Light pollution affects coastal ecosystems, too—this underwater "canary" is warning of the impacts
In the early 20th century, canaries were used as early warning systems in coal mines to alert miners to rising levels of carbon monoxide......»»
Improved mid-infrared nanoscopy enables 30 times clearer view of the insides of bacteria
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially.....»»
Plant sensors could act as an early warning system for farmers
Using a pair of sensors made from carbon nanotubes, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have discovered signals that reveal when plans are experiencing stresses such as heat, light, or attack from i.....»»
Cold Coulomb crystals, cosmic clues: Unraveling the mysteries of space chemistry
While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at l.....»»
Apple 2030 environmental goals: 95% of suppliers now using clean energy
We’ve today received an update on Apple’s 2030 environmental goals, one of which is for the company’s entire supply-chain to be carbon neutral by that date. The company says more than 320 suppliers – representing 95% of the company’s “.....»»
CO₂ worsens wildfires by helping plants grow, model experiments show
By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a UC Riverside study......»»
Researchers reveal oceanic black carbon sink effect driven by seawater microdroplets
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic bla.....»»
Novel method developed for phosphorescent multi-color carbon dots
A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green......»»
From tape measures to space lasers: Quantifying biomass of the world"s tallest forests
In this era of accelerating climate crisis, accounting for all aspects of Earth's carbon cycle is a crucial task. The magnitude of atmospheric carbon burden means trees and forests are limited but important instruments among a suite of mitigation opt.....»»
How to keep Earth from being cooked by the ever-hotter Sun
Here are two options for future humans to keep us in the habitable zone. I’d wager a guess that we are, as a species, rather fond of our home planet (our wanton carbon emissions notwithstanding). But the ugly truth is that the Eart.....»»
Northern permafrost region emits more greenhouse gases than it captures, study finds
Permafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern permafrost region has.....»»
