Researchers from Universidad Carlos III de Madrid (UC3M) and Hospital Universitario Severo Ochoa in Leganés, part of the public health network of the Comunidad de Madrid, have developed a methodology that uses artificial ...

A new study led by astronomers at The University of Texas at Austin proposes a theory that could solve two astronomical riddles at once: the nature of Little Red Dots and the origin of globular clusters. Rather than representing ...

Along the vast ocean floor lives a species of glass sponge known as Venus' flower basket. Though delicate-looking, its exterior belies an exceptionally strong, lightweight skeleton that has intrigued scientists for the past ...

For decades, scientists have crawled through Bobcat Cave on Redstone Arsenal in Huntsville, searching its dark pools and underground passages for rare life. The cave is home to the endangered Alabama cave shrimp, making it ...

In much of Asia, the effects of climate change are felt through an increased frequency of extreme weather events, especially water-related ones. Droughts are becoming more common in mainland Southeast Asia, while periods ...

Photodynamic therapy (PDT) uses a light-sensitive drug and a specific wavelength of light to destroy cancer cells. The treatment has become an important option for certain skin cancers because it can target diseased tissue ...

A new study found that giant sequoias were nearly four times as likely to survive extreme wildfires in forests managed with prescribed burns, which decrease tree mortality. The work is published in the journal Nature Communications.

Archaeologists have uncovered a rare and intricate polychrome mosaic within the remains of a Roman villa beneath Devon farmland. Made up of thousands of red, white and dark blue-gray cubes, the 12 m2 (129 square feet) mosaic ...
