James Cook University researchers have tested frog housing and nursery preferences in the Wet Tropics rainforest of North Queensland, with frogs finding the thermal regulation of concrete shelters to be the perfect tropical ...

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive ...

A 2,000-year-old papyrus fragment, discovered in the archives of the French Institute of Oriental Archaeology in Cairo, reveals 30 previously unpublished verses by Empedocles, a pre-Socratic philosopher of the fifth century ...

A growing network of meltwater lakes at the edge of the Greenland ice sheet is accelerating the flow of major glaciers, potentially increasing the pace of global sea-level rise. Warmer air and sea temperatures have led to ...

In the search to replace antibiotic growth promoters with effective alternatives in modern swine production, plant-based essential oils are showing potential to provide lasting benefits. In a rare long-term public study that ...

Butterfly fossils are rare, and finds that preserve fine anatomical details and wing patterns are an absolute exception. An international research team from Sweden, the U.S., and Germany, led by Dr. Hossein Rajaei, lepidopterist ...

Researchers at Aarhus University have developed a microscopic DNA needle that can deliver molecules directly into cells—and, crucially, help make sure they remain active once they get there. That addresses a major problem ...

As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 ...

With the arrival of spring a few weeks ago, new buds and colors on the trees started to appear. Along with that new growth, a UBC Okanagan researcher has determined that some trees in spring also provide simple, visual clues—raised ...

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever ...

Rivers are rarely the calm, orderly streams we imagine on maps. Over time, their winding paths—called meanders—shift, bend, and occasionally snap off in sudden "cutoff" events that shorten loops and reshape the landscape. ...

Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails from aircraft contribute ...
