Flathead catfish -- native to the Mississippi River basin -- were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the river basin. The impact of the large predator on the waterway's food webs and ecology was unknown, but now a research team is beginning to understand what Susquehanna flatheads are... Read more ›

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to analyze ulrafast processes which up until now were considered to be 'instantaneous': When a laser pulse hits an atom with two electrons, one electron may be ripped out of the atom, while the other electron stays close to the...

Expanding access to new, highly effective weight-loss medications could prevent more than 40,000 deaths a year in the United States, according to a study. The findings highlight the critical need to remove existing barriers that are hindering people's access to effective weight loss treatments and impeding public health efforts to address the national obesity crisis, the researchers said. According to the U.S. Centers for Disease Control and Prevention, about 74%... Read more ›

Researchers describe the full molecular structure of the phage DEV. DEV infects and lyses Pseudomonas aeruginosa bacteria, an opportunistic pathogen in cystic fibrosis and other diseases. DEV is part of an experimental phage cocktail developed to eradicate P. aeruginosa infection in pre-clinical studies. Bacterial viruses, known as phages, are the most abundant biological entities on the planet and are increasingly used as biomedicines to eradicate antibiotic-resistant pathogenic bacteria.

Having happy intimate partners might not only lift our moods, but it also helps us manage stress, especially as we age, according to new research. When comparing individuals' self-reported emotional states and relationship satisfaction with their levels of cortisol, researchers observed that older couples have lower levels of the stress hormone when their partners feel positive emotions. This effect was even stronger for people who reported higher satisfaction in their... Read more ›

A study investigating the complex evolution of two iconic Western Australian landmarks, has traced their transformation over thousands of years and offers a glimpse into their future. Researchers collected sedimentary samples from multiple locations along Perth's coastline, waterways and even the sea floor to track changes which occurred as the ocean levels rose dozens of meters over thousands of years.

Researchers have discovered that GPR31, found in certain immune cells in the human gut, plays a key role in responding to bacterial metabolites and activating immune responses. Specifically, in the presence of metabolite pyruvate, these cells extend dendrites to sample the gut environment, detect pathogens, and activate T cells through GPR31. This discovery could inform the development of new drugs, vaccines, and probiotics that enhance gut immunity by targeting this... Read more ›

A team of scientists has discovered surprising connections among gene activity, genome packing, and genome-wide motions, revealing aspects of the genome's organization that directly affect gene regulation and expression. The findings bolster our understanding of the mechanics behind transcription-dependent motions of single genes -- the dysfunction of which may lead to neurological and cardiovascular disorders as well as to cancer.
