In response, The Economist argued that the president should withdraw from the electoral race with a story that used an image of the presidential seal attached to a walker....

New study reveals the icy, cold climate of Mars’ past, with implications for life

If life exists on alien worlds, scientists expect that the worlds in question would have certain basic properties. There would be carbon, an element essential to the creation of organic molecules.

Are the polls even reliable? Experts examine election polling predictions from 1980 to 2024

During the first debate of the 2024 election cycle, President Biden infamously flubbed his words, trailed off mid-sentence, stared off into space and otherwise acted every bit like a mentally incompetent 81-year-old man. With Biden’s fellow Democrats determined to save democracy from an election-denying Republican — former President Trump — who was recently empowered by the Supreme Court to be a dictator, their experts are now turning to one place for information about the future: Polls

Scientists detect rotten egg smell from exoplanet where it rains molten glass

Scientists have discovered thousands of exoplanets in other solar systems and some of them are especially weird compared to our stellar neighborhood.

But it also rains molten glass at extremely hot temperatures, with the scorching shards flying sideways due to winds that reach speeds of up to 5,000 mph (8,046 kph)....

Out-of-control heat is making Earth more “weird” — and more deadly

For the 13th consecutive month, Earth’s average monthly temperature has broken all previous records, continuing a streak that began in June 2023. Significantly, the European climate service Copernicus added that that the world has been 1.5 degrees Celsius (2.7 degrees Fahrenheit) higher than pre-industrial levels for more than a year, pushing the planet up against the threshold established by the 2015 Paris climate agreement....

The surprising link between neck thickness and health

When fitness experts try to assess a person’s health, they usually perform a series of standard measurements. First they measure a human’s height, then compare that with the circumference of their chest, waist, hips and/or thighs. The goal is to help each individual achieve a thickness that suggests the healthiest percentage of body fat — not so low as to be malnourished, nor so high as to put a person at risk of cardiovascular diseases....
