VLITE 340 MHz image of GLIMPSE-C01 from February 27, 2021. Credit: McCarver et al., 2023. Using the Karl G. Jansky Very Large Array (VLA), astronomers have discovered a millisecond pulsar in the globular cluster GLIMPSE-C01 as part of the VLA Low-band Ionosphere and Transient Experiment (VLITE). This is the first pulsar ever detected in this … Read more
Travel deep enough below Earth’s surface or inside the center of the sun, and matter changes on an atomic level. The mounting pressure within stars and planets can cause metals to become nonconducting insulators. Sodium has been shown to transform from a shiny, gray-colored metal into a transparent, glass-like insulator when squeezed hard enough. Now, … Read more
Schematic image of NK cell-engaging nanodrones (NKeNDs). Credit: UNIST A study led by Professor Sebyung Kang and Professor Sung Ho Park in the Department of Biological Sciences at UNIST has unveiled a remarkable breakthrough in cancer treatment. The research team has successfully developed unprecedented “NK cell-engaging nanodrones” capable of selectively targeting and eliminating cancer cells, … Read more

A graphic illustrating the four possible interactions between two particles, where the arrows indicate the force experienced by the particle of that color due to the gradient surrounding the particle of the other color. The interactions shown in the upper left-hand and lower right-hand corners illustrate reciprocal interactions where the two particles attract each other … Read more

The South Coast Air Quality Management District has extended a no-burn order for much of Southern California through Thursday amid poor air quality. The agency chalks up the bad air to—coincidentally— residents enjoying holiday fires as well … Read more
Dramatic plumes spray water ice and vapor from many locations along the famed “tiger stripes” near the south pole of Saturn’s moon Enceladus. The tiger stripes are four prominent, approximately 84-mile- (135-kilometer-) long fractures that cross the moon’s south polar terrain.

Credit: Unsplash/CC0 Public Domain Florida has long been home to an unnatural assortment of creatures from faraway lands and habitats, and these tourists turned permanent residents have wreaked havoc on the natural ecosystem. You can thank the Burmese pythons slithering around the Everglades for the lack of marsh rabbits, and the Asian swamp eels are … Read more
