Nature-strip gardens are a paradise for pollinators in your street‎

In front of most Australian houses, between the sidewalk and the road, runs a strip of land most people never really think about. In Australia, it's called the nature strip, but it goes by other names in other regions, including a verge, parkway or tree lawn.

A climate threat may lurk beneath Antarctica's last great unknown‎

A region of Antarctica with some of the greatest potential to reshape the natural world and human society is also the least scientifically understood and explored.

Nanoneedle arrays map RNA in fresh tissue without sequencing or amplification‎

Recently, spatial omics has become a powerful tool, enabling researchers to see not only what molecules are present in a tissue, but also where they are located and how they are organized across cells, tissue structures and local microenvironments. This spatial context has deepened our understanding of cancer, neurobiology and immunology. Yet as the field advances, an important question remains: How many of these powerful technologies are ready for routine clinical use?

Informal businesses belong in entrepreneurial ecosystems, review argues‎

A systematic review of informal businesses published in the International Journal of Entrepreneurship and Small Business argues that they should be treated as part of the larger entrepreneurial ecosystem rather than as a peripheral feature of the economy.

Gamma-ray search sets new limits on dark matter annihilation in the inner Milky Way‎

Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects attributed to dark matter, they have not yet been able to determine what it is made of.

Taste shapes support for climate-friendly school meals‎

Students in a new study were neither clearly positive nor negative about more climate-friendly school meals. Whether the food tasted good, was filling and felt familiar played an important role. Students were somewhat more positive about reducing the amount of meat in recipes than about having more all-vegetarian days.

One giant clam contains a month‑by‑month diary of the Great Barrier Reef's climate 200 years ago‎

When you swim through the azure waters of the Great Barrier Reef, there is one creature on the seafloor that's almost impossible to miss: the giant clam. Its huge, fluted shell frames a soft mantle shimmering with electric blue, green and gold.

Hidden X-ray phase revealed in likely neutron star merger‎

An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for Astronomy and Astrophysics (HKIAA) at The University of Hong Kong (HKU), has discovered a previously hidden phase of high-energy activity following the merger of compact stars.

Heat-trapping gas once frozen in Arctic ground is slowly leaking and warming the planet‎

As Ted Schuur stepped along the edges of Smith Lake, a bubble surfaced from the muck underfoot. And then another. They're bubbles of methane, a potent heat-trapping gas made from decomposing plants and animals that had once been stuck in Alaska's frigid permafrost. But that frozen ground is thawing because the Arctic is warming four times faster than the rest of the globe. For thousands of years that frozen ground stored dead plants and animals, but the accelerating thaw is allowing them to decay into methane and carbon dioxide.
