Swirlonic super particles baffle physicists
We report a novel state of active matter--a swirlonic state. It is comprised of swirlons, formed by groups of active particles orbiting their common center of mass. (2021-02-11)

Zebra stripes, leopard spots: frozen metal patterns defy conventional metallurgy
''Stripy zebra, spotty leopard...'' Pattern formation and pattern recognition entertains children and scientists alike. Alan Turing's 1950s model explaining patterns in two-substance systems is used by metallurgists to explain microscopic internal stripes and spots. A study out today explains exotic patterns, counter to Turing's theory, forming on the liquid metal gallium, which melts in the hand. The previously ignored surface-solidification phenomenon improves fundamental understanding of liquid-metal alloys, with a potential patterning tool, and advanced applications in future electronics and optics.

Study reveals jellyfish create a 'virtual wall' to enhance performance
New discovery finds that Jellyfish create a ''ground effect,'' similar to how air squeezes between an airplane and ground during take-off, which builds pressure and a force that boosts performance. Never before has it been proven that an animal can create this phenomenon away from a solid boundary, let alone the open ocean. (2021-01-08)

Monkeys, like humans, persist at tasks they've already invested in
Humans are generally reluctant to give up on something they've already committed time and effort to. It's called the ''sunk costs'' phenomenon, where the more resources we sink into an endeavor, the likelier we are to continue--even if we sense it's futile. A new study shows that both capuchin monkeys and rhesus macaques are susceptible to the same behavior and that it occurs more often when the monkeys are uncertain about the outcome. (2020-12-18)

Male weeds may hold key to their own demise
Scientists are getting closer to finding the genes for maleness in waterhemp and Palmer amaranth, two of the most troublesome agricultural weeds in the US. Finding the genes could enable new 'genetic control' methods for the weeds, which, in many places, no longer respond to herbicides. (2020-12-11)

Science of sandcastles is clarified, finally
Capillary condensation is a textbook phenomenon and omnipresent in our world. For example, children playing on the beach rely on this universal process to hold their sandcastles together. Despite its importance scientists have had to rely on an equation first set by the great Victorian physicist Lord Kelvin 150 years ago - but for the first time a Manchester team led by Nobel laureate Andre Geim can explain how the microscopic process actually works. (2020-12-09)

Experiment to test quantum gravity just got a bit less complicated
Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could settle the issue. However, it requires studying two very large entangled quantum systems in freefall. In a new paper, Mazumdar presents a way to reduce background noise to make this experiment more manageable. (2020-12-08)

A new beat in quantum matter
Oscillatory behaviors are ubiquitous in Nature, ranging from the orbits of planets to the periodic motion of a swing. In pure crystalline systems, presenting a perfect spatially-periodic structure, the fundamental laws of quantum physics predict a remarkable and counter-intuitive oscillatory behavior: when subjected to a weak electric force, the electrons in the material do not undergo a net drift, but rather oscillate in space, a phenomenon known as Bloch oscillations. (2020-11-23)

Analysis paves way for more sensitive quantum sensors
Theoretical researchers at Pritzker Molecular Engineering have found a way to make quantum sensors exponentially more sensitive by harnessing a unique physics phenomenon. (2020-11-16)

Babies' random choices become their preferences
When a baby reaches for one stuffed animal in a room filled with others just like it, that random choice is very bad news for those unpicked toys: the baby has likely just decided she doesn't like what she didn't choose. Researchers have known that adults build unconscious biases over a lifetime of choosing between things that are essentially the same, but finding that even babies do it demonstrates this way of justifying choice is fundamental to the human experience. (2020-10-02)

Earthquake lightning: Mysterious luminescence phenomena
Photoemission induced by rock fracturing can occur as a result of landslides associated with earthquakes. Factors involved in such earthquake lightnings were studied with granite, rhyolite, pyroclastic rock and limestone. (2020-09-28)

Embryos taking shape via buckling
The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures. Although buckling could be the dominant mechanism that triggers invagination, it has never been possible of measuring the tiny forces involved. This gap has finally been filled thanks to a study carried out by scientists from the University of Geneva. (2020-09-14)

More small-scale dark matter gravitational lenses than expected in galaxy clusters
The gravitational pull of cold dark matter in galaxy clusters can distort or bend the light coming from distant background galaxies, in a phenomenon called gravitational lensing. (2020-09-10)

To make a better sensor, just add noise
Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now Penn State researchers have added a small amount of background noise to enhance very weak signals in a light source too dim to sense. (2020-09-03)

Surface deep: Light-responsive top layer of plastic film induces movement
Scientists show that only a thin, topmost layer of the light-dependent azobenzene-containing plastic film needs to be light-sensitive, rather than the entire film, opening up new ways to potentially reduce production costs and revolutionize its use. (2020-08-22)

A stepping stone for measuring quantum gravity
A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves.

(2020-07-10)

Like humans, rats are less likely to help victims in the presence of unhelpful bystanders
A study in rats demonstrates that the bystander effect - a phenomenon in which individuals are less likely to help someone in need with other bystanders around - exists in a non-human species. Furthermore, while rats were less likely to rescue a rodent in need when surrounded by unhelpful bystanders, John Havlik and colleagues also observed that they were more likely to take action when their fellow bystanders were willing helpers. (2020-07-08)

Behind the dead-water phenomenon
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this ''dead water'' being understood. A French team has explained this phenomenon for the first time. (2020-07-06)
