US–Indian space mission maps extreme subsidence in Mexico City‎

One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of the fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth's surface from orbit, unhindered by clouds or vegetation that impede optical sensors and higher-frequency radars.

Overcoming the algorithmic gender bias in AI‑driven personal finance‎

Artificial intelligence is transforming our world and financial services are no exception. AI is reshaping the personal banking sector, but where does it currently stand on gender parity, transparency, and fairness?

From smoking to stigma: How screen stories influence health‎

What people see on screen can shape what they do off it. When actors such as James Dean and Marlon Brando lit cigarettes in 1950s rebel films, smoking came to signify cool, defiance and desire for an entire generation.

Why real-time teamwork dashboards can backfire instead of improving collaboration‎

As digital tools become more common in teamwork, many organizations hope they can help teams collaborate more effectively. But a new study suggests that some uses of tools—such as providing real-time feedback on collaboration via specific metrics—do not necessarily improve how teams work and in some cases may even make performance worse.

Twisting water reveals hidden order across four molecular layers at air-water interface‎

Researchers from the Department of Physical Chemistry at the Fritz Haber Institute and Freie Universität Berlin have revealed the arrangement of water molecules at the interface between liquid water and air. Their findings help to better understand interfacial chemistry, which is largely determined by the specific arrangement of the water molecules. Published in Science Advances, the study shows that one parameter in particular—one that has been neglected until now—is of fundamental importance: the water twist.

Integrated land planning could ease food, energy and biodiversity conflicts worldwide‎

While the world is a big place, humans are making greater and greater demands on the same areas of land. "This means that, unless we use the same land to serve multiple needs and coordinate this effort through planning, it is unlikely that we will have enough land for conservation, food and energy," said Grace Wu, a professor in UC Santa Barbara's Environmental Studies Program.

Heat and cold alter how animals fight disease. As the climate changes, this knowledge may be vital‎

Each animal species has an optimal temperature at which it can metabolize food and its immune system can best fight off pathogens.

DAMPE satellite reveals cosmic rays share spectral break near 15 teravolts‎

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the universe—remain a mystery to scientists. The DAMPE (Dark Matter Particle Explorer) space telescope is tackling this phenomenon, particularly investigating the role that dark matter may play in their formation. This international mission, which includes the University of Geneva (UNIGE), has made a major breakthrough by highlighting a universal feature of these particles. The results are published in the journal Nature.

Drivers help study road-trip mystery: what became of bug splats?‎

Long an emblem of the summer road trip, squashed bugs on the car have become less numerous over the years, many people say—causing concern about the health of the world's insect populations.

How temperature swings impact the growth of young songbirds‎

Climate change threatens to cause increasingly extreme and variable temperature swings, affecting everything from urban infrastructure to global food supplies. In the animal kingdom, the hardest hit may be the youngest and smallest songbirds, according to new research.
