Only rarely does dust ever completely break down or go away. However – and like with nearly all types of air pollution – it can be controlled. Indoors we usually go to great lengths to try to corral dust, relying on everything from cloths, filters, vacuum cleaners and wipes to dust pans and brooms and […]

Oceanographers have great difficulty conducting investigations by ship in Antarctic continental shelf areas where ice is attached to the shore, so a team of researchers have replaced these boat-based studies with sensors attached to seals, which have far less trouble navigating such waters. A study describing the animal-born investigation technique and the researchers’ findings appeared in the […]

Via drug repositioning, Osaka City University creates combination of rifampicin and resveratrol and have shown in mouse models that the nasal administration improves cognitive function without the negative liver side effects of rifampicin alone. Dementia is thought to occur when proteins called amyloid-β, tau, and α-synuclein accumulate in the brain and form oligomers. A research […]

The Alpha variant of SARS-CoV-2 – the first variant of concern – evolved mutations that allowed it to more efficiently suppress the immune system’s early response to infection, according to a new study led by scientists at the UC San Francisco’s Quantitative Biosciences Institute (QBI) and University College London. The researchers have discovered that the variant has […]

Emily Setton removes the lid from a small, plastic dish on her lab bench. Within the clear, rectangular plate are half-circle wells containing hundreds of round beads about the color and size of couscous — the large kind. Setton, a graduate student in the lab of Integrative Biology Professor Prashant Sharma, is just back from a field […]

In the summer of 2014 a strange building began to take shape just outside MoMA PS1, a contemporary art centre in New York City. It looked like someone had started building an igloo and then got carried away, so that the ice-white bricks rose into huge towers. It was a captivating sight, but the truly impressive thing about this building […]

More than one in five women experience irregular menstrual cycles that could keep them from learning they are pregnant until it may be too late to access an abortion under some state laws in effect or under consideration, a new study shows. Researchers from the University of Wisconsin–Madison and National Institutes of Health analyzed anonymized […]

All the royal mummies found in the 19th and 20th centuries have long since been opened for study. With one exception: egyptologists have never been bold enough to open the mummy of Pharaoh Amenhotep I. Not because of any mythical curse, but because it is perfectly wrapped, beautifully decorated with flower garlands, and with face and […]

Sediments in which archaeological finds are embedded have long been regarded by most archaeologists as unimportant by-products of excavations. However, in recent years it has been shown that sediments can contain ancient biomolecules, including DNA. “The retrieval of ancient human and faunal DNA from sediments offers exciting new opportunities to investigate the geographical and temporal […]

An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants. These antibodies target areas of the virus spike protein that remain essentially unchanged as the viruses mutate. By identifying the targets of these “broadly neutralizing” antibodies on the spike protein, it might be possible to design vaccines and antibody treatments […]
