The star marking true north is a good deal heavier than we thought. The North Star is 5.1 times as massive as the sun, astronomers report in work submitted July …
The North Star is much heavier than previously thought Read More
To expand the periodic table, it might be time to go titanium. A new study lays the groundwork to expand the periodic table with a search for element 120, to …
A new element on the periodic table might be within reach Read More
A mind-bending parasite may one day deliver drugs to the brain. Toxoplasma gondii is a single-celled parasite that famously makes mice lose their fear of cats, but also can cause …
Getting drugs into the brain is hard. Maybe a parasite can do the job Read More
NASA’s Perseverance rover has bagged its first hint of ancient microbes on Mars. “We’re not able to say that this is a sign of life,” says Perseverance deputy project scientist …
NASA’s Perseverance finds its first possible hint of ancient Mars life Read More
The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, built …
Dark matter experiments get a first peek at the ‘neutrino fog’ Read More
People with advanced cancers often feel like their bodies are wasting away. That’s because of cachexia, a condition in which impaired metabolism leads to muscle wasting and drastic weight loss …
Stopping cachexia at its source could reverse wasting from cancer Read More
A new look at decades-old data from the Apollo missions has uncovered evidence of tens of thousands of previously unrecognized moonquakes. The results could reveal details about the moon’s inner …
Moonquakes are much more common than thought, Apollo data suggest Read More
Any way you slice it, a paper cut is painful. Magazines, letters and books harbor a devious potential for minor self-induced agony. But other types of paper — like thin …

Forever chemicals are everywhere. They’re in school uniforms, food packaging, cosmetics and personal care products (SNE: 11/18/22; SN: 6/4/19; SN: 6/15/21). They seep into our food and drinking water. And …
Some ‘forever chemicals’ maybe absorbed through our skin Read More
The rotation of the Earth has been measured many times – but never like this. At first, scientists used entangled quantum particles called photons to detect the speed at which …
