Researchers wanted to know if the Clean Air Act is capable of reducing air pollution disparities or if a new approach would be needed. The team compared two approaches that mirror main aspects of the Clean Air Act and a third approach that is not commonly used to see if...
Fossil bird’s skull reconstruction reveals a brain made for smelling and eyes made for daylight
Piecing together the crushed skull of a fossil bird that lived alongside the dinosaurs helped researchers extrapolate what its brain would have looked like: big olfactory bulbs would have meant that this bird, the earliest known animal to eat fruit, had a better sense of smell than most modern birds....
The Environmental Footprint of Food
In an age of industrialized farming and complex supply chains, the true environmental pressures of our global food system are often obscure and difficult to assess.
Evidence for new theory of genetic recombination
New findings suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction.
Laying geological groundwork for life on Earth
New research analyzing pieces of the most ancient rocks on the planet adds some of the sharpest evidence yet that Earth's crust was pushing and pulling in a manner similar to modern plate tectonics at least 3.25 billion years ago. The study also provides the earliest proof of when the...
Bumblebees Revisit Favourite Flowers as Sun Sets
As the sun sets, bumblebees revisit "profitable" flowers they encountered during the day, new research suggests.
Discovery of New Ecosystem – ‘the Trapping Zone’ – Creating Oasis of Life in the Maldives
The Nekton Maldives Mission, involving researchers from the University of Oxford, has found evidence of a previously undescribed ecosystem - ‘The Trapping Zone’ - that is creating an oasis of life 500 metres down in the depths of the Indian Ocean.
The Lightness of Water Vapor Adds Heft to Global Climate Models
Clouds are notoriously hard to pin down, especially in climate science.
Tandem solar cells with perovskite: Nanostructures help in many ways
By the end of 2021, scientists had presented perovskite silicon tandem solar cells with an efficiency close to 30 percent. This value was a world record for eight months, a long time for this hotly contested field of research. Scientists now describe how they achieved this record value with nanooptical...
UK’s oldest human DNA obtained, revealing two distinct Palaeolithic populations
The first genetic data from Palaeolithic human individuals in the UK -- the oldest human DNA obtained from the British Isles so far -- indicates the presence of two distinct groups that migrated to Britain at the end of the last ice age, according to new research. Published today in...
