Black holes' magnetism surprisingly wimpy

Scientists have discovered black holes have significantly weaker magnetic fields than previously thought, with measurements about 400 times lower than estimated. This finding deepens our knowledge of how matter behaves under extreme conditions and could impact nuclear fusion power and GPS systems.

Go with the flow (or against it)

Researchers at Queen's University have successfully used magnetic fields to direct magnetotactic bacteria against strong currents, opening up the potential for these microbes to deliver pharmaceuticals directly to tumors. The team aims to bind therapeutic drugs to the bacterial bodies and release them once they reach their destination.

Identifying individual atmospheric equatorial waves from a total flow field

Researchers developed a new approach to identify individual equatorial waves in wind and geopotential height fields using classical equatorial wave theory. This allows for the temporal and spatial evolution characteristics of equatorial waves, including their initiations, propagations, and interactions with tropical convections.

Gender norms are still important for women's choice of college major

A study suggests that women's conformity to traditional feminine norms affects their choice of college majors. Women conforming more closely to these norms are less likely to pursue STEM fields or arts/humanities, while those who align with caregiving and domesticity norms are more likely to choose STEM or clinical fields.

New and novel technologies successfully demonstrated in soilborne disease study

Researchers have successfully developed a new method to analyze soil microbial communities and their role in the development of Sudden Death Syndrome (SDS) disease in soybean. By profiling microbes, scientists found significant differences between healthy and diseased areas, suggesting that biological factors play a key role in determi...

Drivers of insecticide use

A new study by UC Santa Barbara scientists has found that landscape characteristics, such as crop diversity and field size, affect insecticide use. Crop diversity was shown to reduce insecticide use by 8kg per hectare in table grapes, while larger fields use more insecticide.

With magnetic map, young eels catch a 'free ride' to Europe

Researchers discovered that young European eels detect subtle differences in the earth's magnetic field, helping them swim towards the Gulf Stream, a conveyor belt transporting them to Europe. The findings reveal that juvenile eels use their magnetic map sense to increase their chances of catching a free ride to their destination.

Steering towards grazing fields

A 16-year Nebraska study found minimal negative impacts of grazing cattle on corn stubble on soil properties, except for slight compaction. Grazing may even have a slightly positive effect on soil microbial community structure due to the addition of nutrient-rich manure.
