Harnessing magnetic relaxation: 'Pac-Man effect' enables precise organization of superparamagnetic beads

Particles that are larger than regular molecules or atoms yet remain invisible to the naked eye can form a variety of useful structures, including miniature propellers for microrobots, cellular probes, and steerable microwheels ...

Study determines when and how pterosaurs went from tiny tree-climbers to towering terrestrial titans

The evolutionary adaptations that allowed ancient pterosaurs to grow to enormous sizes have been pinpointed for the first time by paleontologists in the Center for Paleobiology and Biosphere Evolution at the University of ...

Phage cocktail shows promise against drug-resistant bacteria

Researchers have a new battle tactic to fight drug-resistant bacterial infections. Their strategy involves using collections of bacteriophages, viruses that naturally attack bacteria. In a new study, researchers at the University ...

Scientists achieve unprecedented control of active matter

An international research team led by Brandeis University has achieved a major breakthrough in the field of active matter physics, as detailed in a study published this week in Physical Review X. This pioneering research ...

How passion drives or derails team innovation

In companies, innovative ideas often come out of teams. That's why it's so important to have team members who are excited and focused on projects that lead to innovation. However, having team members who are too passionate—especially ...

The sun unleashes its strongest flare this cycle

Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.

What's the best material for a lunar tower?

Physical infrastructure on the moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential ...

Gravitational lens confirms the Hubble tension

We've known the universe is expanding for a long time. The first solid paper demonstrating cosmic expansion was published by Edwin Hubble in 1929, based on observations made by Vesto Slipher, Milton Humason, and Henrietta ...

Ants adapt tool use to avoid drowning

Researchers have observed black imported fire ants using sand to draw liquid food out of containers, when faced with the risk of drowning. This is the first time this sophisticated tool use has been reported in animals. These ...

Nanoscale machines convert light into work

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics ...

Perseverance Rover will peer beneath Mars' surface

After touching down on the Red Planet Feb. 18, 2021, NASA's Mars 2020 Perseverance rover will scour Jezero Crater to help us understand its geologic history and search for signs of past microbial life. But the six-wheeled ...

Oldest monkey fossils outside of Africa found

Three fossils found in a lignite mine in southeastern Yunan Province, China, are about 6.4 million years old, indicate monkeys existed in Asia at the same time as apes, and are probably the ancestors of some of the modern ...

California bullet train staff recommend German operator

The agency overseeing California's bullet train project recommended Friday that a U.S. subsidiary of a German rail company design and operate a train segment from the Central Valley to Silicon Valley in its early stages.
