Fossil footprint discoveries and what they tell us
Footprints on a sandy surface don't usually last long: they're washed away by water, wiped out by wind or covered over by new tracks. At certain sites in southern Africa, though, some traces of animals have lasted for many thousands or even millions.....»»
Research tracks 66 million years of mammalian diversity
When trying to understand the present, it's helpful to look to history. New research from the University of Nebraska–Lincoln examined the fossil record going back 66 million years and tracked changes to mammalian ecosystems and species diversity on.....»»
Brazilian researchers discover dinosaur fossil after heavy rains in Rio Grande do Sul
A team of Brazilian scientists has discovered a fossilized skeleton of what they believe is one of the world's oldest dinosaurs after heavy rains in the southern state of Rio Grande do Sul accelerated the natural process of erosion......»»
North America auto manufacturing footprint unlikely to change through 2029, Chicago Fed says

Cutting-Edge Technology Could Massively Reduce the Amount of Energy Used for Air Conditioning
Roughly 10 percent of the world’s energy is used for cooling, with much of the necessary electricity generated by fossil fuels. Companies need to make AC much more efficient—as soon as possible......»»
Atomically controlled MXenes enable cost-effective green hydrogen production
A total of 137 countries around the world have signed a "net-zero" climate change agreement to end fossil fuel use and achieve zero carbon emissions by 2050. Hydrogen is being touted as the next green energy source because it emits only water and oxy.....»»

Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
To help with climate change, carbon capture will have to evolve
The technologies are useful tools but have yet to move us away from fossil fuels. Enlarge / Bioreactors that host algae would be one option for carbon sequestration—as long as the carbon is stored somehow. (credit: Getty Images.....»»
Researchers demonstrate anomalous Brewster effect in metamaterials
The Brewster reflectionless effect stands out as one of the simplest yet pivotal discoveries in manipulating waves. Initial investigations were limited to isotropic materials, but later, thanks to the advent of metamaterials, the phenomenon was found.....»»
Nanocarbon catalyst design unlocks new avenue for sustainable fuel additive production
Vehicle exhaust from fossil fuel combustion constitutes a main source of air pollutants like carbon dioxide and carbon monoxide. To mitigate air pollution, researchers are looking into additives to fuels like dimethoxymethane (DMM). But DMM productio.....»»
