A 50-year-old idea about electromagnetic waves known as the Zel’dovich effect has been tested by physicists in the lab, and proven to be correct. Advertisement The idea behind the Zel’dovich effect came from a strange place. In 1969, British physicist and mathematician Roger Penrose suggested that energy could be extracted from black holes by lowering […]

The species (Gypaetus barbatus) […]
Incredible World-First Footage Shows Elusive Orcas Hunting And Eating Dolphins Near Chile
A little-known population of orcas living off the coast of Chile has been seen hunting and eating dusky dolphins for the first time. The behavior may offer insights into the lives and diets of all orcas in the southern hemisphere, which could help future conservation efforts. Advertisement Off the coast of Chile is the Humboldt […]
COVID-19 Virus Can Develop Drug Resistance – But Not Very Often, And Not For Long
A small study of 156 people with COVID-19 has found that mutations that confer resistance to antiviral drugs were “commonly detected”, especially in immunocompromised patients. The authors stress that most of these mutations were transient and occurred at low frequencies – the results do not mean that drug-resistant strains of SARS-CoV-2 are going to become […]
“Exceptional” 320-Million-Year-Old Fossil Ecosystem Could Hold Earliest Signs Insects Laid Eggs
The Pennsylvanian might make up a hefty chunk of one of Earth’s most important periods, the Carboniferous, but we know relatively little about the land ecosystems that existed in its earliest days. Now, thanks to the discovery of an “exceptionally preserved” fossil site in Massachusetts, researchers are beginning to fill in the gaps. Advertisement The […]
High Above The Amazon Rainforest, A “Shocking” Discovery Of Airborne Forever Chemicals
In the balmy air above the Amazon rainforest, nasty human-made chemicals called PFAS have been discovered for the first time. While it’s known that “forever chemicals” have become ubiquitous in the natural world, the researchers behind the discovery have described it as “shocking”. Advertisement An international team of scientists collected air from a 325-meter-tall (1,066-foot) […]
This Winged Fish Uses Strange Tongue-Like “Legs” To Taste The Seafloor – Yes, Really
Scientists have just discovered the mechanism through which a winged fish uses its “legs” to taste the seafloor. The peculiar fish is so good at tasting the seabed, in fact, that other animals follow it for clues on where to find food. Isn’t the ocean just absurd? Advertisement Every now and then an animal comes […]
Nearly 36 Million Hectares Of US Wetlands Could Be Stripped Of Federal Protections
A recent Supreme Court ruling has seen calls for clarification after a study found that it could result in nearly all of the nontidal wetlands in the conterminous USA being stripped of federal protections. Advertisement The ruling in question was over Sackett v. Environmental Protection Agency, a case that concerned the scope of the 1972 […]
California’s 2014 Plastic Bag Ban Flopped, So They’re Trying Again With A New One
A decade ago, California became the first US state to ban single-use plastic bags. It proved to be a massive failure. Hoping to rectify the problem, the Golden State is doubling down with a new, even bigger plastic bag law. Advertisement The initial 2014 ban prohibited grocery stores from distributing free single-use plastic bags for […]
World-First Ruby Grown In-Situ From A “Ruby Seed” Planted In A Platinum Ring
For the first time, a ruby has been grown in situ by planting a “ruby seed” in a platinum ring. The novel approach could transform the jewelry industry as it demonstrates that, theoretically, we no longer need to mine to get great gemstones. The ruby seed used to grow the stone in situ can be […]
Fossils Of Mars’ Climate Show A Different World 2 Billion Years Ago
We know that Mars was different in the past. Flowing water, abundant ice, and a denser atmosphere were the main features of the ancient Red Planet. All of that is gone, but the evidence remains. Planetary scientists have conducted an in-depth analysis of the various terrains present on Mars and found fossilized evidence of the […]

We Need More Rare Earth Elements – Extinct Volcanoes May Be The Place To Find Them
Minerals formed from iron-rich magma contain concentrations of so-called rare earth elements. Identifying deposits formed from this magma around extinct volcanoes could be the path to ensuring these elements are widely available, and heading off potential global conflicts and shortages.
