A new, Yale-led study suggests the 21st century will see an expansion of tropical storms — hurricanes, cyclones, and typhoons — into mid-latitude regions, which includes major cities such as New York, Boston, Beijing, and Tokyo. Writing in the journal Nature Geoscience, the study’s authors said tropical storms could migrate northward and southward in their respective ...
Playing is important for the development of complex social, emotional, physical, and cognitive skills. Play provides young individuals with a safe space to practice new behaviors without grave repercussions. While most animals engage in play, only humans engage in rule-based games. Which kinds people play — competitive or cooperative — may depend on their cultural ...
Something big happened to the planet about a million years ago. There was a major shift in the response of Earth’s climate system to variations in our orbit around the Sun. The shift is called the Mid-Pleistocene Transition. Before the MPT, cycles between glacial (colder) and interglacial (warmer) periods happened every 41,000 years. After the MPT, ...
The universe was created about 13.8 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to traverse space freely. That light, the cosmic microwave background (CMB) radiation, comes to us from every direction in ...
Habitability on Mars may be limited because it is too small to hold onto large amounts of water, new research from Washington University in St. Louis suggests. Water is essential for life on Earth and other planets, and scientists have found ample evidence of water in Mars’s early history. But Mars has no liquid water ...
Researchers used computer modeling to study potential new phases of matter known as prethermal discrete time crystals (DTCs). It was thought that the properties of prethermal DTCs were reliant on quantum physics, the strange laws ruling particles at the subatomic scale. However, the researchers found that a simpler approach, based on classical physics, can be ...
Is the Standard Model of particle physics incorrect at key points? Recently, there has been an increase in experimental observations that deviate from the predictions of this widely accepted physical theory. A current study by the University of Bonn now provides even stronger evidence for the existence of “new physics.” The final version of the ...
A combination of a once-debunked 19th-century identification of a water-carrying iron mineral and the fact that these rocks are extremely common on Earth, suggests the existence of substantial water hidden on Mars, according to a team of geoscientists. Peter J. Heaney, professor of geosciences, said: “One of my student’s experiments was to crystalize hematite. She ...
In archaeometallurgy, the study of ancient metal artifacts, archaeologists have historically taken a top-down approach, meaning that the jewelry, tools, weapons, and other metal artifacts they discover have come to signify a dominant ruling group that exerted overarching control over how to use such resources. The Penn Museum’s Joyce White and Elizabeth Hamilton have a different idea. In ...
An international study of 55 countries has shown a marked increase in the number of overweight women globally, with wealthy, educated, and urban women heavier than their counterparts. Ph.D. candidate Md. Mehedi Hasan from The University of Queensland’s Institute for Social Science Research (ISSR) said the number of overweight women increased in 50 countries from 1990 to 2018, while ...
