Clear-cutting can make catastrophic floods 18 times more frequent with effects lasting more than 40 years, according to a new UBC study.

At the forefront of discovery, where cutting-edge scientific questions are tackled, we often don't have much data. Conversely, successful machine learning (ML) tends to rely on large, high-quality data sets for training. So how can researchers harness AI effectively to support their investigations?

An international team of astronomers has performed multi-band radio observations of diffuse radio emission in a galaxy cluster known as Abell 3558. As a result, the observational campaign detected that the cluster hosts a peculiar mini-halo. The finding was detailed in a paper published July 10 on the arXiv preprint server .

An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee-ring effect." As a droplet evaporates, the edges dry faster than the center, pulling fluid—and suspended particles—outward. This creates a dense ring of material at the periphery of the droplet. It's a familiar sight to anyone who's spilled tea or coffee, but for scientists working on coatings and inks, this effect can be frustrating. In many applications, a uniform deposit is far more useful than a ring.

Polyester plastics, commonly found in synthetic textiles and plastic components of home appliances, are notoriously difficult to recycle. In a study recently published in the Proceedings of the National Academy of Sciences, researchers from France unveiled a clever method for breaking down polyester waste into reusable building blocks using heat and leveraging the residual catalysts embedded within the plastic during the manufacturing process, eliminating the need for tedious sorting.

Researchers have developed a novel copper-based alloy that exhibits a special shape memory effect at temperatures as low as -200°C. The work has been published in the journal Communications Engineering.

Oregon State University pigment researchers are using a rare mineral discovered in Norway more than a century ago as a road map for creating new yellows, oranges and reds that are vibrant, durable, non-toxic and inexpensive.

A research team led by Associate Professor Boon Siang Yeo from the Department of Chemistry at National University of Singapore (NUS) has developed a new way to turn carbon dioxide, a greenhouse gas, into valuable liquid hydrocarbons, which are the main components of fuels like gasoline and jet fuel.

Three stories above the Field Museum's exhibits, rows and rows of taxidermied chipmunks filled a tray in the museum's mammal archives. Pointing to two of the oldest critters, mammalogist Stephanie Smith picked up the pair of chipmunks off the tray, balancing them in the palm of her hand.

An ancient leg bone uncovered in Africa might provide a step forward in understanding how dinosaurs and their close relatives evolved.
