Coastal chemistry improves methane modeling
Scientists at Oak Ridge National Laboratory are using a new modeling framework in conjunction with data collected from marshes in the Mississippi Delta to improve predictions of climate-warming methane and nitrous oxide emissions from soils in coasta.....»»
New modeling of complex biological systems could offer insights into genomic data and other huge datasets
Over the past two decades, new technologies have helped scientists generate a vast amount of biological data. Large-scale experiments in genomics, transcriptomics, proteomics, and cytometry can produce enormous quantities of data from a given cellula.....»»
Organosilicon chemistry offers options for replacing PFAS in food and medical industries
Due to the unique properties of PFAS, almost no other chemical substances can compete with them. That explains why it is so hard to find a replacement for these toxic "forever chemicals," which accumulate in the environment and do not break down over.....»»
New research estimates carbon emissions from 22 million stream reaches across the US
Using a sophisticated new modeling approach, researchers at the University of Massachusetts Amherst have estimated carbon dioxide emissions from inland waters to 22 million U.S. lakes, rivers and reservoirs. It marks the first time this approach has.....»»
Computer modeling research reveals the changing history of a global ice sheet
Imagine that a massive ice sheet covered Canada and oozed down over a large part of the northern United States, like icing spilling down the side of a cake. That was the situation somewhere between 19,000 and 26,000 years ago. The ice sheet covered l.....»»
The world promised to tame methane: Emissions are still rising
Sitting in his cramped office in Paris, Manfredi Caltagirone admits that one of the world's highest-profile efforts to cut methane emissions so far isn't stopping the gas from escaping and warming the atmosphere......»»
Psychological inoculation: Combining two simple tools could combat election misinformation
A popular new strategy for combating misinformation doesn't by itself help people distinguish truth from falsehood but improves when paired with reminders to focus on accuracy, finds new Cornell University-led research supported by Google......»»
Saturday Citations: On chimpanzee playwrights; the nature of dark energy; deep-diving Antarctic seals
This week, researchers reported the world's second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don't like bees, which.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»
Satellite imagery may help protect coastal forests from climate change
Sea-level rise caused by climate change poses a serious and often unpredictable threat to coastal forests, and new tools are needed to help mitigate damage and allocate conservation resources......»»
Saturn"s moon Titan may have a 6-mile-thick crust of methane ice — could life be under there?

Chemists just broke a 100-year-old rule and say it"s time to rewrite the textbooks
UCLA chemists have found a big problem with a fundamental rule of organic chemistry that has been around for 100 years—it's just not true. And they say, It's time to rewrite the textbooks......»»
Safe, efficient method for synthesizing allenes opens up new possibilities for drug development
A research team jointly led by Professor Sung You Hong and Professor Jan-Uwe Rohde has unveiled a novel method for synthesizing allenes—a series of compounds integral to drug development and synthetic chemistry—without relying on hazardous, highl.....»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Bones from shipwreck suggest right- or left-handedness could affect how clavicle chemistry changes with age
A new study of human skeletal remains from the wreck of the 16th century English warship "Mary Rose" suggests that whether a person is right- versus left-handed may influence how their clavicle bone chemistry changes as they age. Dr. Sheona Shankland.....»»
AI training method can drastically shorten time for calculations in quantum mechanics
The close relationship between AI and highly complicated scientific computing can be seen in the fact that both the 2024 Nobel Prizes in Physics and Chemistry were awarded to scientists for devising AI for their respective fields of study. KAIST rese.....»»
How life began on Earth: Modeling the ancient atmosphere
The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers various atmospheric chemical reactions to estimat.....»»
Experimental setup simulates Arctic methane explosions
Russian researchers have developed an experimental setup that will help simulate gas-dynamic processes and predict explosions in Arctic soils......»»
Modeling study addresses future algal blooms and human impact
What does the future hold for our lakes globally—clear waters or widespread algal blooms? A new study is the first to model and project algal blooms on a global scale under different socio-economic and climate scenarios. Conducted by the UK Centre.....»»
A new app for tracking coastal flooding during hurricanes
A web-based application that gathers crowdsourced data to identify flooding and inform policy in coastal communities provided University of South Florida scientists with essential data from hurricanes Helene and Milton......»»
Is it true that trees pollute the air?
Methane is the most famous volatile organic compound (VOC) in our atmosphere. This week, our host George Zaidan follows up on a Reactions subscriber's question about the 600 teragrams of a less famous VOC released every year: isoprene......»»
