Why Ho Chi Minh City's pollution sources may have been misread for years

Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution is tracked by looking at levels of levoglucosan, a chemic

New Horizons tracks solar wind slowdown as interstellar atoms add drag

A new Southwest Research Institute (SwRI) study based on data from NASA's New Horizons spacecraft has uncovered insights into why the solar wind gradually slows as it moves toward the edge of the solar system and the boundary with interstellar space. The study "The Gradual Slowin

Mice actively seek better views to make visual decisions, virtual reality experiments show

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version of active sensing is infotaxis, which describes how an

Sound waves reconstruct Alaska fireball path after cameras miss key details

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of

400-year-old painting reveals a bat's secret diet

Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As technology has advanced, these methods have grown far more

Nautilus array to track missing exoplanet atmospheres

Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can't be directly imaged yet, so astronomers must get creative in how they search for signs of life, also called biosignatures. Presently, p

AI could bring satellite crop monitoring to the world's most vulnerable farms

Small farms grow much of the world's food, but from space they are nearly invisible. Their fields are tiny and ill-defined, and the satellite tools built to track crops were designed for the large, uniform fields of industrial agriculture, not the sub-hectare plots that feed many

Natural born killers—tracking immune cells as they cluster around cancer

There is a constant war going on in your body. Working against you are viruses and cancer cells growing uncontrollably, threatening your tissues and organs. Fighting on your side are immune cells such as lymphocytes, a type of white blood cell that includes T cells and B cells. B

Alpine butterflies track warming uphill, but habitat loss may pose bigger risk

A new study published in the journal Alpine Entomology has found that alpine butterflies in the Swiss National Park are closely matching the pace of local warming in their range shift to higher elevations.

Tracking your employees doesn't make them more productive

In June, TD Bank told staff that it would begin running software called WorkiQ on their work computers, tracking time spent in browsers, internal chat and meeting apps. The rollout has revived public debate about workplace surveillance. But the issue extends well beyond one bank.

Deep learning reveals nanoparticle shape from routine tracking analysis without new hardwa

Researchers at the University of Tokyo and the Innovation Center of NanoMedicine (iCONM) have developed an artificial intelligence (AI) approach that identifies the morphology of nanoparticles in liquid using data from standard nanoparticle tracking analysis (NTA), a widely used

Making the 'invisible' visible: How high-speed movies could change the way scientists stud

High-speed movies of microscopic worms may sound like a dull night at the cinema, but this advanced imaging capability could help scientists better understand how diseases begin and progress, track subtle changes in cells and study how the body responds to treatments.
