Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2...
New high-performance solar cell material
A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly...
AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production
An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.
Vehicle brakes produce charged particles that may harm public health
Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.
New study quantifies health impacts from oil and gas flaring in U.S.
A new study finds that pollution from oil and gas venting and flaring results in $7.4 billion in health damages, more than 700 premature deaths, and 73,000 asthma exacerbations among children annually. Researchers also conclude that emissions are underreported and controlling emissions is not only profitable for operators, but also...
Alaska dinosaur tracks reveal a lush, wet environment
A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.
Scientists propose new theory that explains sand ripples on Mars and on Earth
Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one...
Range-shifting fishes are climate-change losers, according to new research
Fish populations that experience rapid-range shift decline noticeably, up to 50 per cent over a decade. The populations affected most are those living on the northern poleward edges of their species' range. Researchers combined data from two large databases to examine the population numbers of range-shifting species. Their analysis revealed...
Higher carnivorous dinosaur biodiversity of famous Kem Kem beds, Morocco
An international team of palaeontologists applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.
Cheetahs’ unrivalled speed explained by their ‘sweet spot’ size, finds Imperial study
A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.
