Study: Ancient enzymes can contribute to greener chemistry
A research team at Uppsala University has resurrected several billion-year-old enzymes and reprogrammed them to catalyse completely different chemical reactions than their modern versions can manage. The method can be used to develop sustainable...
Study: How nutrient-starved cells recycle internal components
The idea of the cell as a city is a common introduction to biology, conjuring depictions of the cell's organelles as power plants, factories, roads, libraries, warehouses and more. Like a city, these structures...
Researchers use artificial intelligence to strengthen power grid resiliency
America's power grid system is not only large but dynamic, which makes it especially challenging to manage. Human operators know how to maintain systems when conditions are static. But when conditions change quickly, due...
Study: 40% of O’ahu, Hawai’i beaches could be lost by mid-century
The reactive and piecemeal approach historically used to manage beaches in Hawai'i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O'ahu, Hawai'i could be...
Study: Income, race are associated with disparities in access to green spaces
Access to green spaces in metro areas--parks, trails, even the tree cover in a neighborhood - is largely associated with income and race, new research indicates.
Researchers combined census-block-group demographic and socio-economic data with satellite...
Researchers carry out first space-based measurement of neutron lifetime
Scientists have found a way of measuring neutron lifetime from space for the first time - a discovery that could teach us more about the early universe.
Knowing the lifetime of neutrons is key to...
Study: Snapshot of exploding oxygen
"The smaller the particle, the bigger the hammer." This rule from particle physics, which looks inside the interior of atomic nuclei using gigantic accelerators, also applies to this research. In order to "X-ray" a...
Study: Dragonflies reveal mercury pollution levels across US national parks
A citizen science program that began over a decade ago has confirmed the use of dragonflies to measure mercury pollution, according to a study in Environmental Science & Technology.
The national research effort, which grew...
Research reveals plunge in lithium-ion battery costs
Analysis quantifies a dramatic price drop that parallels similar improvements in solar and wind energy, and shows further steep declines could be possible.
The cost of the rechargeable lithium-ion batteries used for phones, laptops, and...
Scientists a step closer to eco-friendly hydrogen fuel production
Griffith University researchers are aiming to unlock a catalytic process that will enhance the breakdown of water, into hydrogen and oxygen and bring Australia a step closer to creating clean efficient hydrogen fuel.
Australia’s National...
