3D dynamic model offers more accurate hazard assessments for earthquakes

An international study published in Communications Earth & Environment has advanced earthquake simulations to better anticipate the rupture process of large earthquakes.

Using data for the Turkey earthquake of February 2023, the scientists have developed a detailed 3D dynamic model that provides a more accurate understanding of the strong shaking during this earthquake and hence information for future seismic hazard assessments. The research was led by King Abdullah University of Science and Technology (KAUST) Professor Martin Mai and scientist Bo Li.

The Turkey earthquake was responsible for the death of tens of thousands of people. It was marked by a doublet, which describes two separated by a short time. The first fractured a long stretch of the fault approximately 350 km long, breaking different sections in succession. Just hours later, a second massive rupture followed, amplifying the destruction. Doublets do not show typical aftershock behavior and are a challenge to mathematically describe.

Finding friendship at first whiff: How scent influences our choice of friends

The room is crowded and noisy. There are conversations all around, and the residual smell of popcorn and beer hangs in the air. Yet two women meeting for the first time can judge within minutes whether they have the potential to be friends—guided as much by smell as any other sense, according to new Cornell psychology research.

“People take a lot in when they’re meeting face to face. But , which people are registering at some level, though probably not consciously, forecasts whether you end up liking this person,” said Vivian Zayas, professor of psychology in the College of Arts and Sciences (A&S). “It’s amazing, our attunement to other people, even without being consciously aware of how in tune we are.”

In a study of heterosexual women, Zayas and first author Jessica Gaby, Ph.D., found that personal, idiosyncratic preferences based on a person’s everyday scent, captured on a T-shirt, predicted how much women liked their interaction partner following four-minute chats across a table in a crowded room. These face-to-face conversations, in turn, influenced how participants later judged the T-shirt scent alone.

Researchers discover new third class of magnetism that could transform digital devices

A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times.
