Insecticides containing flupyradifurone and sulfoxaflor can have devastating effects on honey bee health. The substances damage the insects' intestinal flora, especially when used in conjunction with a common fungicide, making them more susceptible to disease and shortening their life span. The two insecticides were considered harmless to bees and bumblebees...
Lack of access to healthy food may raise risk of death from heart failure
A study reviewing data from nearly 3,000 U.S. counties has found an association between lack of access to healthy food and increased rates of death from heart failure. Living in a community with access to more grocery stores and local, healthy food resources was significantly associated with lower rates of...
Research shows care from an allergist results in lower health care costs for children with peanut allergy
Care from an allergist is associated with a reduction in total health care costs for U.S. children with peanut allergy, new research finds.
Real-time air quality data ‘life saving’
Research has found sharing real-time air quality readings in developing countries can reduce air pollution and lead to lower mortality rates.
A new approach, not currently described by the Clean Air Act, could eliminate air pollution disparities
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....
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...
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...
