Phys.org / Bacterial invasion proteins could improve detection of live crop pathogens
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published ...
Phys.org / Tiny oyster larvae rely on gravity to feed
Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution ...
Medical Xpress / From 7,000 drugs to one active against resistant strains: AI advances pneumonia drug repurposing
Streptococcus pneumoniae is a bacterial pathogen that causes life-threatening infections, including pneumonia and meningitis. These infections are commonly treated with antibiotics, but antibiotics are becoming less effective ...
Phys.org / First-of-its-kind preventive phage therapy provides promising results against Salmonella
The mammalian gut microbiome teems with a delicate balance of bacteria and the viruses that keep them in check, called bacteriophages, or phages. Each bacterial species usually has its own set of phage partners.
Phys.org / Engineers solve puzzle of Arctic sea ice movement
Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially ...
Phys.org / Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show
When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, ...
Phys.org / Rivers may be carrying more microplastics into the world's oceans than previously thought
Microplastics are a modern environmental menace and a potential threat to human health. These tiny pieces of plastic, measuring from 1 to 5,000 micrometers, come mainly from larger plastics as well as sources such as paints ...
Medical Xpress / Metabolite buildup reveals how aggressive brain tumors activate nearby neurons
Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from ...
Phys.org / A 16-minute train delay shows how a solar storm disrupted Victorian technology
A 178-year-old mystery surrounding one of the earliest recorded examples of space weather affecting technology has been solved by an international team led by Lancaster University.
Medical Xpress / 'Momnesia' is real—scientists find a biological explanation for temporary forgetfulness during pregnancy
Many women say the same thing during pregnancy: They walk into a room and forget why, misplace their keys or struggle to follow a conversation. This phenomenon, often called "pregnancy brain" or "momnesia," has long lacked ...
Phys.org / Ultrathin membranes unlock nano-infrared views of biomolecules in water
Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: ...
Phys.org / A world 20 light-years away reveals surprisingly organized, Jupiter-like weather
Scientists from Trinity College Dublin have developed a way to unravel changing weather patterns on distant worlds. Using this approach, they discovered that the weather on a well-studied brown dwarf, SIMP 0136, previously ...
