Biodegradable bags not currently recommended for recycling organic waste
Bags made from biodegradable materials for collecting organic household waste have been available on the market for several years. Now researchers in a large-scale pilot study have conducted an extensive investigation into whether these bags fully de.....»»
Trio wins Nobel Prize in chemistry for work on quantum dots, used in electronics and medical imaging
Three scientists based in the U.S. won the Nobel Prize in chemistry Wednesday for their work on quantum dots—tiny particles just a few atoms in diameter that can release very bright colored light and whose applications in every day life include ele.....»»
New research shows how companies could be gaming their reported greenhouse gas emissions
New research by academics at King's Business School has shown that companies are able to "game" their reported greenhouse gas emissions to an extent that is both financially and environmentally material because of the discretion they have around the.....»»
Scientists discover a durable but sensitive material for high energy X-ray detection
X-ray technology plays a vital role in medicine and scientific research, providing non-invasive medical imaging and insight into materials. Recent advancements in X-ray technology enable brighter, more intense beams and imaging of increasingly intric.....»»
New method can better identify sneaky sugars on viruses" spiky weapons
To effectively repel an enemy invasion, it helps to have accurate intelligence about that enemy's weaponry and attack plan. Medical scientists laboring to repel infectious viruses, such as those that cause COVID-19 and HIV, now have a better method f.....»»
Capturing carbon dioxide with electricity: A microbial enzyme inspires electrochemistry
Humans continuously emits greenhouse gases, worsening global warming. For example, carbon dioxide (CO2) accumulates dramatically over the years and is chemically very stable. Yet, some microbes capture CO2 using highly efficient enzymes. Scientists f.....»»
As the world warms, intense tropical cyclones are starting earlier, study finds
Intense tropical cyclones have tended to occur around three days earlier per decade since the 1980s, according to a study published in Nature. This seasonal shifting may be related to ocean warming, primarily driven by greenhouse gas emissions......»»
Researchers propose a unified, scalable framework to measure agricultural greenhouse gas emissions
Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, a team led by scientists at the University of Illinois Urba.....»»
Government policies work to reduce greenhouse gas emissions, analysis finds
Policies designed to reduce greenhouse gas emissions have been effective, however more stringent regulations are needed to limit global warming to the Paris temperature goals, finds a new analysis by UCL researchers of international efforts to fight.....»»
Colorado has a new plan to reduce greenhouse gases. Critics say it fails those most impacted by air pollution
Colorado's air regulators have approved a new rule that will require the state's 18 largest manufacturers to reduce their greenhouse gas emissions, but the plan is receiving pointed criticism from environmental advocates who say loopholes will allow.....»»
From seafloor to space: New bacterial proteins shine light on climate and astrobiology
Gigatons of greenhouse gas are trapped under the seafloor, and that's a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice trap methane gas, preventing it from escaping and bubbling up into the atm.....»»
Quantifying national emissions of methane worldwide
Methane (CH4) stands as the second most important greenhouse gas caused by human activities after CO2 and is responsible for 0.6°C global warming since preindustrial times......»»
Scientists marry MRI, ultrasound, and optoacoustics for improved medical exams
Physicians and researchers rely on biomedical imaging to examine the structure and function of living tissue. This enables disease diagnostics and experiments that reveal the mechanisms behind pathologies and ways to treat them. The most popular tech.....»»
Inside the Race to Stop a Deadly Viral Outbreak in India
Quick thinking and medical sleuthing allowed Kerala to contain a potentially disastrous Nipah virus outbreak this month—but with viral spillovers happening more frequently, containment is a fragile shield......»»
Extensive methane gas leakage from the deepest seabed of the Baltic Sea discovered
During a research expedition led by Linnaeus University and Stockholm University to the deepest parts of the Baltic Sea in the Landsort Deep researchers recently discovered an area with extensive emissions of the powerful greenhouse gas methane from.....»»
Diamond materials as solar-powered electrodes: Spectroscopy shows what"s important
It sounds like magic: photoelectrodes could convert the greenhouse gas CO2 back into methanol or N2 molecules into valuable fertilizer—using only the energy of sunlight......»»
Tiny bubbles could reveal immune cell secrets and improve treatments
Macrophages are cells vital to the immune system and could possibly inform cell-based therapies for a variety of medical conditions. However, realizing the full potential of macrophage therapies relies on being able to see what these cellular allies.....»»
Researchers develop biodegradable optical fiber to measure or modulate electrical current in the body
Electrical signals control a vast number of activities in the human body, from exchanges of messages between brain neurons and stimulation of the heart muscle to the impulses that enable hands and feet to move, among many other examples. To monitor o.....»»
