Bella moths use poison to attract mates: Scientists are closer to finding out how
Researchers sequence the bella moth genome, which they used to pinpoint specific genes that may confer immunity to noxious alkaloids.
The spiciness of mustard may depend on soil microbes
New study finds microbes may influence the taste of mustard seeds.
AI tool creates ‘synthetic’ images of cells for enhanced microscopy analysis
Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as ‘synthetic data’ to train an AI model to better carry out single-cell segmentation.
World’s oases threatened by desertification, even as humans expand them
Oases are important habitats and water sources for dryland regions, sustaining 10% of the world’s population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases’ fragile existence. N…
Eye-opener: Pupils enlarge when people focus on tasks
Normally, a person’s pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person’s pupils also dilate when they are concentrating on tasks. In particular, th…
Liquid droplets shape how cells respond to change
New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to hyperactive signaling a…
Life goals and their changes drive success
Though life goals change over time, a study of teen goals indicates that goals of education and high prestige can drive success.
This alloy is kinky
Researchers have uncovered a remarkable metal alloy that won t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy keeps its shape and resists cracking at both hig…
To find life in the universe, look to deadly Venus
Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.
Everest mountaineer’s letters digitized
Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
3 in 5 parents play short order cook for young children who don’t like family meal
While most parents of preschool and elementary aged children strive to give their children a balanced, nutritional diet, some of their strategies to promote healthy eating may backfire, a national poll suggests.
Study explores possible future for early Alzheimer’s diagnostics
Digital memory test and a blood sample — this combination will be tested for its potential to identify early Alzheimer’s disease in a new research study. Over a hundred healthcare centers are part of the study that is now inviting participants to sign…
Giant galactic explosion exposes galaxy pollution in action
Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
Switching off the light to see better
Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limi…
