Conspiracy theories meet real news: How QAnon tries to hijack the Internet‎

"When people think of extremists, they tend to think of neo-Nazis," said Francesco Campisi, a lecturer at Université de Montréal's School of Criminology. "But there are many other fringe groups that may not be violent yet can give rise to extremism."

How river DNA can track fish, frogs, fungi and human feces all at once‎

A single scoop of water from an Irish river has revealed evidence not only of Ireland's only frog species—as expected—but also signs of the dreaded B. dendrobatidis fungus, marking the first time this devastating amphibian disease has been spotted in the country and exposing a previously unknown risk to Ireland's frog population.

Communication gaps may hinder social innovation‎

New research from the Durham University Management and Marketing Department shows that misunderstandings between investors and founders are a major reason why social innovation ventures fail to grow. In many cases, they collapse altogether.

'Ghost of the forest' returns to Kenya as conservationists reintroduce rare antelope into the wild‎

The mountain bongo has become the "ghost of the forest," hard to spot amid the dense shrubs due to its ability to camouflage.

CRISPR safeguard changes how engineered microbes can be controlled‎

Engineered microorganisms are widely used in industrial biotechnology and biopharmaceutical applications, including the production of biofuels, sustainable chemicals, and therapeutic compounds. However, concerns remain regarding the unintended environmental release and uncontrolled proliferation of genetically engineered microbes. For this reason, biocontainment technologies, which are designed to prevent microorganisms from surviving outside controlled environments, have become increasingly important in both academia and industry.

Heavy Atlantic rain can block African aerosols from fertilizing Amazon, study finds‎

How are cold air masses advancing in the United States connected to fertilizers carried by "flying rivers" from Africa that nourish the soils of the Brazilian Amazon? An article published in Geophysical Research Letters reveals an atmospheric connection between these distant regions.

Organic luminescent radicals enable bright circularly polarized light in the near-infrared region‎

Circularly polarized light has properties that make it useful in a growing range of technologies, from next-generation 3D displays to bioimaging tools that can detect signals deep within living tissues. One way to produce this kind of light is with the help of chiral molecules—compounds that have a mirror-image form to which they cannot be perfectly superimposed. Among these, small organic molecules (SOMs) offer tunable emission wavelengths.

Scientists trace latest interstellar comet's home to a cold, isolated corner of the Milky Way‎

The comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system, astronomers reported Thursday.

Bee more specific: New radar tech could improve identification and tracking of key pollinators‎

Scientists from Trinity and Technical University of Denmark have developed a new radar-based technique that could address a critical gap in global conservation efforts, by transforming how we identify and track the insects that are actually responsible for pollinating plants.

The ocean is fighting climate change: How people are trying to help it‎

We replaced the stove with plywood, turning the kitchen of the dive boat into an impromptu research lab. Plugging in wires and connecting tubing, we assembled a scientific instrument within the cramped cabin. Then we cast off into Halifax Harbor, Canada, surveying the turquoise waters for signs of an unusual test: could we use the ocean itself to remove carbon dioxide from the air?
