Phys.org / How did inbred brown tree snakes take over the island of Guam?
If you look up invasive species in a textbook, there's a good chance you'll find a picture of a brown tree snake. Native to Australia and the South Pacific, the brown tree snake arrived on Guam sometime after World War II, ...
Phys.org / Small tropical islands face dangerous humid heat by end of the century
Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed ...
Medical Xpress / New wearable ring tracks glucose, ketone and other biomarkers in sweat simultaneously
Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor ...
Phys.org / Quantum Zeno effect could freeze computations as qubit systems scale up
The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today's supercomputers—from optimizing logistics to simulating molecules. This goal is coming within reach as the number ...
Phys.org / Quantum dots reveal hidden light waves on metal surfaces
Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging ...
Phys.org / Oxygen collisions at the LHC show new indications of extreme state of matter
All four main LHC experiments have found new signs that oxygen and neon collisions may create the extreme state of matter that existed during the first microseconds after the Big Bang.
Science X / Beneath pale ash, a quantum microscope reveals hidden traces of Neanderthal fire use preserved for millennia
An ancient hearth at El Salt (Spain) is giving up its secrets—not with flames, but with physics. Scientists have already established that Neanderthals used to make fires at this site (spanning from 80,000–45,000 years ago), ...
Phys.org / Can a robot tutor give too much help? Why timing matters
A learner stands in a room with a bottle, a cup and a book. The task is to figure out, step by step, where each object belongs in the room. Under the table? Or perhaps on the chair? A humanoid robot gives the instructions—but ...
Medical Xpress / Spontaneous changes in brain state influence the readiness to form memories, neuroscientists find
Most everyday moments are quickly forgotten, while others stay with us for a lifetime. How the brain determines which memories are retained and which are lost remains an open question.
Phys.org / Why Europa's hidden ocean may be more difficult to reach than scientists thought
Europa, one of Jupiter's icy moons, has long fascinated scientists because of what may lie beneath its frozen shell: a global ocean of liquid water. That hidden ocean has made Europa one of the most compelling places in the ...
Medical Xpress / Large-scale brain analysis reveals multiple pathways to placebo effects on pain
Scientists have long known that expectations can reduce pain. What remained unclear was whether different ways of generating placebo effects rely on the same biological mechanisms. A new study published in Nature Communications ...
Medical Xpress / Death of girl in Chinese gene-editing trial kept secret: Report
A 6-year-old Chinese girl died last year after receiving an experimental gene therapy to correct a non-life-threatening condition, according to an investigation by Science and Retraction Watch.
