Scientists have discovered a low-cost method to significantly reduce this pollution from hydrogen internal combustion engines by improving the efficiency of their catalytic converters. The researchers found that infusing platinum in catalytic converters with a highly porous material called Y zeolites greatly enhances the reactions between nitrogen oxides and hydrogen, converting unhealthful nitrogen oxides into harmless nitrogen gas and water vapor.

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have now provided new insights into the process, emphasizing the critical role of both chaos and order. Read more ›

Researcherers say a pair of experiments with children ages 4 to 7 shows that, given children's natural skepticism and early exposure to the internet's boundless misinformation, it is crucial for adults to teach them practical fact-checking skills. Instead of attempting to completely sanitize their online environment researchers argue adults should focus on equipping children with tools to critically assess the information they encounter.

Smiling during conversations often elevates the experience of knowing someone, but this understanding has been subjective. A new study investigated the reciprocal relationship between people who indulge in smiling during face-to-face conversations. The researchers found that speakers smile more when listeners smile more, particularly in paired individuals of the same biological sex. These findings provide evidence of synchronized smiling behavior, highlighting the influence of facial expressions on interper Read more ›

Studying microscopic layers of dirt dug from the Tam Pa Ling cave site in northeastern Laos has provided a team of archaeologists further insights into some of the earliest evidence of Homo sapiens in mainland Southeast Asia. The site, which has been studied for the past 14 years, has produced some of the earliest fossil evidence of our direct ancestors in Southeast Asia but now a new study has reconstructed...

Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises -- especially when NASA's Hubble Space Telescope takes a close-up look at it. Hubble's new observations of the famous red storm, collected 90 days between December 2023 to March 2024, reveal that the GRS is not as stable as it might look. The... Read more ›

A new study has found some cancers to be slightly more frequent in people with multiple sclerosis (MS) than in people without MS. Types of cancers found to have a small increased risk include bladder, brain and cervical cancers. The study does not prove that MS increases a person's risk of cancer. It only shows an association.

Cerebral adrenoleukodystrophy (CALD) is a rare progressive, genetic brain disease that primarily presents in young boys, causing loss of neurological function and ultimately leading to early death. Researchers have shown that six years after treatment with the first gene therapy approved for CALD, 94 percent of patients have had no decline in neurological functioning, with over 80 percent remaining free of major disability.

Researchers have discovered new understanding of bacterial photosynthesis. Using cutting-edge techniques, investigators have unveiled intricate detailed images of the key photosynthetic protein complexes of purple bacteria. These images shed new light on how these microorganisms harness solar energy. Read more ›
