6+ hour, 5+ min ago   (288+ words) The curious case of the solar system's missing silver has had scientists scratching their heads for years....

1+ week, 4+ day ago   (482+ words) There are certain laws of physics that heat must follow. Take Kirchhoff's law of thermal radiation, for example, which applies the idea of reciprocity to heat, and dictates that a surface's ability to absorb heat at a specific angle and…...

2+ mon, 2+ week ago   (292+ words) There could be nearly 330 years' worth of lithium hiding beneath the Appalachian Mountains, which stretch like a stony spine across the eastern United States....

3+ mon, 3+ week ago   (464+ words) Scientists are always pushing the boundaries of solar cell efficiency – how much of the available sunshine gets turned into electricity – and a new approach to the technology has resulted in an astonishingly high 130 percent 'quantum yield'. It's a process known…...

5+ mon, 5+ day ago   (687+ words) Space junk returning to the Earth is introducing metal pollution to the pristine upper atmosphere as it burns up on re-entry, a new study has found. Published today in the journal Communications Earth & Environment, the study was led by Robin…...

6+ mon, 2+ week ago   (959+ words) In recent years, the way drivers interact with cars has fundamentally changed. Physical buttons have gradually disappeared from dashboards as more functions have been transferred to touchscreens. Touchscreens in vehicle dashboards date back to the 1980s. But modern cars consolidate functions…...

8+ mon, 3+ week ago   (536+ words) For decades, scientists have tried to understand how the Sun's corona (outer atmosphere) gets so blisteringly hot while its surface stays relatively balmy – and now a new study has delivered a big clue. An international team of scientists reports the…...

8+ mon, 4+ week ago   (499+ words) An object that struck an Australian man's Tesla as he was traveling along a highway may have been a meteorite. Andrew Melville-Smith, a veterinarian from Whyalla in South Australia, told the Australian Broadcasting Corporation (ABC) that the object hit his…...

9+ mon, 6+ day ago   (600+ words) It rains on the Sun, the gigantic thermonuclear orb that burns with the multi-million-degree 'fires' of fusion. This rain is made of superheated plasma, and researchers might have discovered its secret: quickly shifting flows of elements such as iron, silicon,…...

9+ mon, 3+ week ago   (1116+ words) A proposed constellation of satellites has astronomers very worried. Unlike satellites that reflect sunlight and produce light pollution as an unfortunate byproduct, the ones by US startup Reflect Orbital would produce light pollution by design. The company promises to produce…...
