Biodegradable medical gowns may add to greenhouse gas
The use of disposable plasticized medical gowns—both conventional and biodegradable—has surged since the onset of the COVID-19 pandemic. Landfills now brim with them......»»
Recent advances in built-in electric-field-assisted photocatalytic dry reforming of methane
Methane (CH4) and carbon dioxide (CO2) are the two main greenhouse gases that cause global warming. Dry reforming of methane (DRM) technology can simultaneously utilize two greenhouse gases to produce hydrogen (H2) and carbon monoxide (CO), meaning D.....»»
Ultralight ultrafast enzymes: Isotopes more powerful than previously thought
In a recently published study in Angewandte Chemie International Edition, researchers at the Department of Medical Biochemistry and Biophysics (MBB) at Karolinska Institutet have questioned the old paradigm surrounding isotopes of light elements—ca.....»»
Carbon dioxide becomes more potent as climate changes, study finds
A team of scientists found that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere......»»
Taking climate action with Earth observation
As global temperatures records are smashed and greenhouse gas emissions reach new highs, a new report from the UN Environment Programme finds that current pledges under the Paris Agreement put the world on track for a 2.5°C–2.9°C temperature rise.....»»
Study shows Black households pay higher heating costs, seek cold-related medical care more often
Ticking up the thermostat a degree or two is going to cost anyone more money, but a new study from UConn researchers suggests Black households pay more to keep their homes comfortable, in part due to increased cold sensitivity......»»
The big emitters: the United States
The United States, the world's second largest emitter of greenhouse gases, has pledged to halve its emissions by 2030 compared to 2005 levels—but so far is failing to stay on target, analysts say......»»
Healthcare changes can slash climate impact: global health agency
Global healthcare has a significant impact on the environment but there are ways it could slash its greenhouse gas emissions without increasing production costs, the international health agency Unitaid said Tuesday......»»
Cybellum achieves significant market share growth among leading medical device manufacturers
Cybellum announced that Cybellum has significantly increased its market share amongst leading medical device manufacturers (MDMs). Working with companies across the industry, Cybellum’s approach provides risk visibility throughout the full product.....»»
Researchers triple carbon nanotube yield for LEDs, solar cells, flexible and transparent electronics
Skoltech scientists have found a way to improve the most widely used technology for producing single-walled carbon nanotube films—a promising material for solar cells, LEDs, flexible and transparent electronics, smart textiles, medical imaging, tox.....»»
Compact accelerator technology achieves major energy milestone
Particle accelerators hold great potential for semiconductor applications, medical imaging and therapy, and research in materials, energy and medicine. But conventional accelerators require plenty of elbow room—kilometers—making them expensive an.....»»
Researchers develop coating process for fabrics that kills or inhibits growth of pathogens
Countless times a day, patients, visitors and medical staff in hospitals touch surfaces of all kinds. Door handles, railings or elevator buttons can serve as transport vehicles for pathogens such as hospital germs or viruses. Smooth surfaces are comp.....»»
Extreme rainfall increases exponentially with global warming: Study
State-of-the-art climate models drastically underestimate how much extreme rainfall increases under global warming, according to a study published Monday that signals a future of more frequent catastrophic floods unless humanity curbs greenhouse emis.....»»
Scientists "fingerprint" methane to track a climate change culprit
Methane is the second-most abundant greenhouse gas in Earth's atmosphere, and its emissions have been rapidly—and mysteriously—rising since 2007. Though pervasive, the origin of the colorless compound is tricky to trace, complicating efforts to c.....»»
Human rights law demands climate change adaptation, researchers say
Continued high emissions of greenhouse gases mean the well-being of all people now depends on profound changes in policies and practices to effect climate change adaptation......»»
5,200 years of migrations from Mexico to California may be the origin of a mystery language
Research led by Nathan Nakatsuka of the Department of Genetics at Harvard Medical School, Boston, has found evidence supporting migrations into California from Mexico and the presence of Mexican-related ancestry in Central and Southern California sta.....»»
Carbon neutrality likely to increase extreme weather events by 2050, finds study
Climate modeling based upon Earth's current greenhouse gas emissions trajectory predicts a worst-case scenario of 4.3°C warming of the planet by 2100 if sufficient measures are not implemented. While the Paris Climate Agreement has been adopted by 1.....»»
Mind the gap: Study shows estimates of current land-based emissions vary between models due to differing definitions
A new study published in Nature demonstrates that estimates of current land-based emissions vary between scientific models and national greenhouse gas inventories due to differing definitions of what qualifies as "managed" land and human-induced, or.....»»
U.S. finalizes rule requiring states to set transportation emission targets
The Federal Highway Administration, part of the U.S. Department of Transportation, said the rule adds a new method for measuring and reporting greenhouse gases associated with transportation and allows states to track performance......»»
