A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults
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
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
Why put solar panels on green space when we could put them over car parks?
The long-running series in which readers answer other readers’ questions considers a hot topic within renewable energyThis week’s replies: Are there places on Earth where humans haven’t been?I would like to know why we build solar farms over green space, when we could just put th
Starwatch: Waning crescent moon pairs up with the Seven Sisters
Cluster might look like a mini version of the Plough unless you grab your binocularsIn the early hours of 11 July, the waning crescent moon will be gliding past the beautiful Pleiades star cluster, which is also known as M45 or the Seven Sisters.The chart shows the view looking e
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.
From birdsong to galaxies: Unleashing the potential of citizen science
Everyone could contribute dramatically more to scientific knowledge if given better recognition, administrative support and funding stability, new research has found. An international collaboration of 16 organizations used surveys and group discussions to identify key challenges,

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
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
