Imaging the proton with neutrinos

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured experimentally. Neutrino experiments use targets that are nuclei made of many protons and neutrons bound together. This complicates interpreting those measurements to infer proton structure. By...

Weight stigmatizing experiences associated with disordered eating behaviors

Researchers have found positive parenting and family factors were associated with reduced risk for disordered eating behaviors but did not lessen the influence of weight-stigmatizing experiences on disordered eating in young people. Weight stigmatizing experiences -- like weight teasing and hurtful weight-related comments -- were associated with higher prevalence of disordered eating behaviors.

Candida auris: deadly fungal infections spreading across US at ‘worrisome’ rate

Between 2020 and 2021 cases of Candida auris doubled, with symptoms including antibiotic-resistant high fever with chillsPotentially deadly fungal infections with Candida auris are spreading rapidly in US healthcare facilities, with cases nearly doubling between 2020 and 2021, the US Centers for Disease Control and Prevention said on Monday.The number of cases rose by 44% to 476 in 2019, up from...

Developing smart light traps inspired by photosynthesis

Plants use photosynthesis to harvest energy from sunlight. Now researchers at the Technical University of Munich (TUM) have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

Watch a spider show off some fancy footwork—and footwear—to woo a mate

If the 1980s taught us anything, it’s that a pair of legwarmers is a surefire way to get attention. That’s a lesson male wolf spiders appear to have taken to heart. The arachnids are far more likely to score a mate if they sport fuzzy appendages when they do their mating dance, assuming the lighting is just right. Researchers ran courtship trials withmembers of the diverse,...

Be a Solar Active Region Spotter!

Want to help unravel the Sun’s secrets? Come track sprawling magnetic fields as they rotate across the Sun! (Credit: Emily Mason/NASA) “Active regions” are large concentrations of magnetic field on the Sun, home to dramatic phenomena such as solar flares that can affect the Earth and other planets. Scientists need your help tracking these active regions as they return from their...

Research team finds indirect evidence for existence of dark matter surrounding black holes

Dark matter does not emit or reflect light, nor does it interact with electromagnetic forces, making it exceptionally difficult to detect. Nevertheless, a research team from The Education University of Hong Kong (EdUHK) has proven that there is a substantial amount of dark matter surrounding black holes. The study results are published in the journal The Astrophysical Journal Letters.

To ward off aging, stem cells must take out the trash

In humanity's ongoing quest for the elixir of life, the science keeps pointing to stem cells. Research increasingly shows that maintaining stem cell fitness promotes a long healthspan, and new findings show keeping stem cells clean and tidy is an integral step.

Seeing through sediment reveals Red Sea tectonics

Geologists have long contested the structure of the Red Sea. Many regard it as an extended rift basin where two continental plates are actively moving apart, while others see it as a fully developed ocean with a mid-ocean ridge and seafloor spreading.

Galaxy changes classification as jet changes direction

A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise. The work is published in Monthly Notices of the Royal Astronomical Society.

Headlines with a negative twist boost the consumption of online news, demonstrates study

If it bleeds, it leads. The old newspaper adage tells us that gory headlines are good for sales. It is a tactic that tabloid newspapers have long exploited in their battle against dwindling circulation. Today's news market is no longer determined by print sales, but by the range offered by online media and social networks. However, this has made the fight for attention all the more intense. There...

Have your cake and print it: the 3D culinary revolution is coming

Engineers show 3D printing’s potential by turning cartridges of paste and powder into cheesecakeIt was perhaps no surprise, when researchers set out to push the boundaries of 3D printing, that their attempts to rattle out cheesecakes were not immediately successful.The first trial started well enough, but as the printer gradually built up the dessert, squirting one layer and then the next, the...

New species of trapdoor spider confirmed in Australia

A trio of arachnologists at Queensland Museum Collections and Research Center, has described the rediscovery of a species of giant trapdoor spider believed to live in hidden parts of Queensland, Australia. In their study, reported in Journal of Arachnology, Michael Rix, Jeremy Wilson and Paul Oliver conducted a four-year field study looking for evidence of the spider and conducted a DNA analysis...

RNA molecule uracil found in asteroid Ryugu samples

Researchers have analyzed samples of the asteroid Ryugu collected by the Japanese Space Agency's Hayabusa2 spacecraft and found uracil, one of the informational units that make up RNA, the molecules that contain the instructions for how to build and operate living organisms. Nicotinic acid, also known as Vitamin B3 or niacin, which is an important cofactor for metabolism in living organisms, was...
