Intricate molecular mechanisms help bacteria evade immune detection

Northwestern Medicine scientists have identified a novel mechanism used by the bacteria responsible for gonorrhea to evade immune detection and achieve widespread infection, according to a recent study published in the Proceedings of the National Academy of Sciences. Neisseria go

Gravitational waves reveal hidden populations within black hole mergers

Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. Yet despite this wealth of data, a fundamental question ha

Machine learning calibration of biosensors for microcystin toxin monitoring in freshwater

Portable screen-printed carbon electrode (SPCE) biosensors offer a rapid, low-cost way to detect microcystin-lysine-arginine (MC-LR), an extremely potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Even at low concentrations, MC-LR can damage the li

Stephen Hawking's black hole laws just got a major upgrade

Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wav

Space jam: astronomers detect ‘raspberry sugar’ on dust cloud in Milky Way

Detection of erythrulose shows compounds that are key to life can form in expanse between starsA natural sugar found in raspberries and used in fake tan lotions has been detected in an enormous cloud of dust and gas that lurks near the heart of the Milky Way.The discovery does no

Widely-used method for assessing stream health doesn't work very well

A new study finds a widely used technique for assessing the health of freshwater streams is not effective at detecting a range of water quality problems, including those related to acidity, oxygen levels and the presence of pathogens.

New 3D thermal cloak hides objects from heat in any direction

Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal detection.

Six massive landslides discovered on icy Pluto

Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in three impact craters.

AI-powered electronic nose can distinguish tens of thousands of odors

A research team has presented a roadmap for developing an "artificial olfactory system" that detects odors like the human nose and analyzes them using artificial intelligence (AI) by leveraging metal-organic frameworks (MOFs). The team systematically organized and reviewed key re

Underwater microphones detect dolphins in Sea of Japan bays about once every ten days

When residents of two coastal communities along the Sea of Japan reported observing dolphins in nearby waters, it caught the attention of some scientists. The marine environment has been changing rapidly in the Sea of Japan, which is partially enclosed by the Japanese archipelago

Magnetic fingerprint of a cosmic explosion detected for the first time

Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is operated by the U.S. National Science Foundation National Radio Astronomy Observat

Roman telescope will spot distant black holes that shred stars

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. New research suggests NASA's Nancy Grace Roman Spac
