A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults

Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully grown adults with their mature plumage, all set to find an

Ancient teeth from Siberia rewrite the plague's timeline, dating back to over 5,500 years

Scientists have found the oldest known evidence of the plague, which sparked deadly outbreaks dating back about 5,500 years ago—some 200 years earlier than previously thought.

BC and Alberta fall behind on fracking safety distances for residents

In May, Prime Minister Mark Carney announced plans to double the capacity of Canada's electricity grid by 2050, using natural gas in the name of "powering Canada strong." Almost all Canadian natural gas these days is derived from hydraulic fracturing—known as fracking—an industri

Phylogenomics reveals angel insects' ancestry, resolving century‑old 'Zoraptera problem'

Zoraptera, also known as angel insects or ground lice, are tiny termite-like insects generally found underneath bark or in decaying wood. The Zoraptera group includes a few dozen known insect species that closely resemble each other.

Larger brain, smaller face: Human evolution took a different course than previously though

A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size of the face and jaw—may be far less attributable to directed natural selection than scientists have

Hidden fungal networks deliver carbon to green plants, experiment confirms

Beneath forests, grasslands and wetlands lies a hidden underground network of fungi known as mycorrhizal networks, sometimes nicknamed the "wood-wide web." These fungi live in partnership with plant roots, helping plants absorb nutrients from the soil in exchange for carbon compo

Newly identified marine bacterial enzyme opens new route to building bioactive compound li

Many important medicines and agricultural compounds have origins in natural products made by microorganisms. One such compound is prodigiosin, a vivid red pigment produced by certain bacteria. Beyond its color, prodigiosin and related compounds known as prodiginines have attracte

Researchers break a fundamental rule to create a new concept: Heat that can be directed an

Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, limits the ability to independently control heat absorptio

Isotopic signatures link hot spring magmatic water to the subducting Pacific Plate

Water flowing from hot springs near volcanoes often contains a mixture of meteoric water that has percolated underground and a deeper component known as magmatic water. Researchers at the University of Tsukuba used numerical simulations and isotopic data to show that magmatic wat

Using quantum entanglement to secure ground-to-satellite timing

From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying atomic clocks transmit time-stamped signals to recei

Day-night ocean warming helps explain why El Niño outpaces La Niña in models

Researchers have long known that there is an asymmetry in the El Niño-Southern Oscillation (ENSO), the confluence of wind and water currents that creates warm El Niño events and cooler La Niña events. Large-scale climate models tend to underrepresent this asymmetry for reasons th
