Analysis by assistant professor of environment and society and sociology at Brown found that press releases expressing opposition to climate action were twice as likely to receive news coverage as those supporting action.
The cost of lithium-ion batteries for phones, laptops, and cars has plunged over the years, and an MIT study shows just how dramatic that drop has been. The change is akin to that of solar and wind energy, and further declines may yet be possible, the researchers say.
VTT has successfully produced coffee cells in a bioreactor through cellular agriculture. The innovation can help to make the production of coffee more sustainable. The first batches produced by VTT in a laboratory in Finland smell and taste like conventional coffee.
A largely overlooked space between cells in women’s brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.
Every day is different when you work on a nature reserve, but nothing could have prepared our reserves team at Rutland Water Nature Reserve for the day when they made the palaeontological discovery of a lifetime.
What’s really happening when we see earthworms on a soggy sidewalk? It's probably not what you think.
The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a…
The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources.
The origin of the term is credited to Dr Gary L. Henderson, of the University of California at Davis. A designer drug is based on the structure of an existing drug – which may be naturally sourced from a plant (like cocaine or morphine ) or be synthetic (like amphetamine ) - but with a slightly different structure…

The risk of Lyme disease has increased due to climate change and warmer temperature. A rheumatologist offers advice on how to best avoid ticks while going outdoors.
COLLEGE PARK, Md. – In a head-to-head comparison of masks worn by people with active COVID-19, the inexpensive “duckbill” N95 came out on top, stopping 98% of COVID-19 particles in the breath of infected people from escaping into the air. Led by researchers from the University of Maryland School of Public Health…
UChicago breakthrough creates methane fuel from sun, carbon dioxide and water
See how OpenAI, PerturbAI, and Scripps Research used distributed AI agents to uncover promising research leads in data from millions of brain cells.
Researchers at ETH Zurich are using iron to store hydrogen safely and for long periods. In the future, this technology could be used for seasonal energy storage.
How exactly does the antiviral drug remdesivir counter SARS-CoV-2 - the coronavirus strain responsible for COVID-19? And how well?
Gland, Switzerland, 9 April 2026 (IUCN) – The emperor penguin and Antarctic fur seal are now both Endangered, according to The IUCN Red List of Threatened Species™. Climate change in Antarctica is leading to changes in sea-ice that are projected to cause the emperor penguin population to halve by the 2080s, while…
The Nobel Prize in Physiology or Medicine 2026 was awarded jointly to Karl Deisseroth, Peter Hegemann and Georg Nagel "for their discoveries concerning light-gated ion channels and optogenetics"
Light can transmit more data while consuming far less power than electricity, and an engineering feat brings optical data transport closer to replacing wires.
