Researchers shrink camera to the size of a salt grain

Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view.


Leading researchers publish new definition of quantum nanoscience

The scale of investment in quantum computation, simulation and sensing is growing at a tantalizing pace. Harnessing the nanoscale to engineer useful quantum effects is a transformative capability of huge relevance to industries ...

Waterfall sounds used as a telltale sign of water loss

Waterfalls have a specific threshold of water flow that must be maintained to preserve their characteristic sound and appearance, according to research that used audio recordings and images to monitor waterfalls in Europe. ...

Molding, patterning and driving liquids with light

Jiming Bao, professor of electrical and computer engineering at the University of Houston, has developed a new fluid that can be cut open by light and demonstrated macroscopic depression of ferrofluid, the kind of fluid ...

New discovery opens the way for brain-like computers

Research has long strived to develop computers to work as energy efficiently as our brains. A study, led by researchers at the University of Gothenburg, has succeeded for the first time in combining a memory function with ...

A new model that automatically generates movie trailers

Trailers, short video clips that introduce new movies, are often crucial elements in the promotional strategies employed by film production companies. To be most effective, trailers should briefly summarize a movie's plot, ...

High-flying morpho butterflies evolved into efficient gliders

Some morpho butterflies live and fly high in the canopy of the Amazonian rainforest, and have evolved into highly-efficient gliding flyers. These results revealed by Wageningen University & Research and published in Science ...

Sparking new insights into dye chemistry

Fluorophores, a chemical compound that can emit light, can be used as fluorescent labels for bioimaging, and fluorescent probes to detect a wide range of chemical species and physical parameters.

Tracking down microplastics in Antarctica

Microplastics are everywhere, even in the most remote places. Where do these tiny pieces of plastic come from? Researchers from the University of Basel and the Alfred-Wegener Institute have shown that it takes precise analysis ...

Biopesticides can be used to degrade aflatoxin in crops

The Food and Agriculture Organization (FAO) estimates that 25% of global food crops are contaminated with different types of fungal toxins, such as aflatoxins, highly toxic and carcinogenic substances produced by certain ...
