Students discover bright lensed galaxy in the early universe

The night sky is a natural time machine, used by cosmologists to explore the origins and evolution of the universe. Reaching into the depths of the past, a class of undergraduate students at the University of Chicago sought to do the same—and uncovered an extraordinarily distant galaxy in the early cosmos.

Study highlights the role of forest fuels amid a warming climate

California's drought of 2012-2016 killed millions of trees in the Sierra Nevada—mostly by way of a bark beetle epidemic—leaving a forest canopy full of dry needles. A study published from the University of California, Davis, and the U.S. Forest Service helps answer concerns about what effect de

A climate in crisis calls for investment in direct air capture, news research finds

There is a growing consensus among scientists as well as national and local governments representing hundreds of millions of people, that humanity faces a climate crisis that demands a crisis response. New research from the University of California San Diego explores one possible mode of response: a massively funded program to deploy direct air capture (DAC) systems that remove CO2 directly from the ambient air and sequester it safely underground.

Low cost chlorine dispensing device improves tap water safety in low-resource regions

A team of researchers led by engineers at Tufts University's School of Engineering and Stanford University's Program on Water, Health and Development have developed a novel and inexpensive chlorine dispensing device that can improve the safety of drinking water in regions of the world that lack financial resources and adequate infrastructure. With no moving parts, no need for electricity, and little need for maintenance, the device releases measured quantities of chlorine into the water just before it exits the tap. It provides a quick and easy way to eliminate water-borne pathogens and reduce the spread of high mortality diseases such as cholera, typhoid fever and diarrhea.

Honeybees reveal how our floral landscape has changed over the last 65 years

Honeybee historians might seem like a flight of fancy but these tiny pollinators have been helping researchers from the National Botanic Garden of Wales track how the UK's fields, hedgerows, wild spaces and gardens have changed since the 1950s.Using cutting-edge DNA barcoding techniques, scientists at the Botanic Garden identified which plants modern-day honeybees visited most often by looking at the pollen grains trapped within honey.

Concept for a hybrid-electric plane may reduce aviation's air pollution problem

At cruising altitude, airplanes emit a steady stream of nitrogen oxides into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Nitrogen oxides, or NOx, are a major source of air pollution and have been associated with asthma, respiratory disease, and cardiovascular disorders. Previous research has shown that the generation of these chemicals due to global aviation results in 16,000 premature deaths each year.
