Rumbles detected deep inside Mars have promoted speculations over volcanic activity on the red planet from “possible” to “likely”. After studying a cluster of marsquakes detected by NASA’s InSight lander, researchers have concluded that molten magma is probably still present beneath the crust of Mars – meaning that the surface of Mars continues to be

Using non-invasive techniques to manipulate our emotions, it might be possible to curtail the screaming horrors that plague our sleep. A study conducted on 36 patients diagnosed with a nightmare disorder showed that a combination of two simple therapies reduced the frequency of their bad dreams. Scientists invited the volunteers to rewrite their most frequent

Commonly assumed to be silent, 53 animals have had their ‘voices’ added to a family tree of vocalizations in an effort to determine when acoustic communication emerged in evolutionary history. The species that are finally being heard come from four different animal clades, including 50 turtle species, the South American lungfish (Lepidosiren paradoxa), a limbless

NASA scientists, using a tool designed to study how dust affects climate, have identified more than 50 spots around the world emitting major levels of methane, a development that could help combat the potent greenhouse gas. ​”Reining in methane emissions is key to limiting global warming,” NASA Administrator Bill Nelson said in a press release

Scientists continue to blow through data transmission records, with the fastest transmission of information between a laser and a single optical chip system now set at 1.8 petabits per second. That’s well in excess of the amount of traffic passing across the entire internet each second. Here’s another comparison: the average broadband download speed in

Plastic recycling rates are declining even as production shoots up, according to a Greenpeace USA report out Monday that blasted industry claims of creating an efficient, circular economy as “fiction.” Titled “Circular Claims Fall Flat Again,” the study found that of 51 million tons of plastic waste generated by US households in 2021, only 2.4

Scientists can now “decode” people’s thoughts without even touching their heads, The Scientist reported. Past mind-reading techniques relied on implanting electrodes deep in peoples’ brains. The new method, described in a report posted 29 Sept. to the preprint database bioRxiv, instead relies on a noninvasive brain scanning technique called functional magnetic resonance imaging (fMRI). fMRI

Researchers at Europe’s science lab CERN, who regularly use particle physics to challenge our understanding of the universe, are also applying their craft to upend the limits to cancer treatment. The physicists here are working with giant particle accelerators in search of ways to expand the reach of cancer radiation therapy, and take on hard-to-reach

Teeny tiny jumping spiders, with their wondrous eyes, seem to be able to do something we’d only ever seen before in vertebrates: distinguishing between animate and inanimate objects. In a 2021 test, wild jumping spiders (Menemerus semilimbatus) behaved differently when presented with simulated objects of both kinds, in ways that indicated an ability to discern

When lightning flashes above, plants on the ground may respond in kind. Scientists have long been aware that plants and trees can emit small, visible electric discharges from the tips of their leaves when the plants are trapped beneath the electrical fields generated by thunderstorms high overhead. These discharges, known as coronas, are sometimes visible

Millions of people are now suffering from long COVID, which presents with a staggering array of possible symptoms that can linger for months, or even years. To provide more answers to this frustratingly relentless condition, researchers have tested an association between mental stresses and long COVID. These stressors include depression, anxiety, and types of distress

Pure water is an almost perfect insulator. Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a

After generations of speculation, scientists have finally managed to track European eels the entire way back to their breeding grounds in the Sargasso Sea – following their movements thousands of kilometers along what is considered one of the most impressive animal migrations in nature. Scientists are gushing with excitement because this is the first direct
