Phys.org / Fluorescent nanosensor detects key gut biomarker in minutes for faster testing
A research collaboration has developed a novel fluorescent nanosensor capable of rapidly detecting indole-3-propionic acid (IPA), an emerging biomarker linked to gut health and disease. The breakthrough is described in the ...
Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Phys.org / One of our planets may be missing, and it could explain why the solar system looks the way it does
Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions ...
Phys.org / Nanoengineered materials can store and release hydrogen at room temperature
Energy engineers worldwide are working on various new technologies that could help to limit greenhouse gas emissions on Earth and address climate change. One proposed alternative to polluting fossil fuels, such as petrol, ...
Phys.org / Tiny-armed alvarezsauroid dinosaurs might have been insect eaters, fossil scans suggest
Dinosaurs are estimated to have roamed Earth for over 165 million years, gradually evolving over time to survive in changing environments. Among the many fascinating groups of dinosaurs known to have lived on our planet are ...
Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
Phys.org / Atlantic 'cold blob' may be reshaping Indian monsoon, steering rain northwest
The Indian monsoon has shifted over the past quarter century. Northwest India now receives substantially more rain than it once did, while a lack of rain sends the Indo-Gangetic Plain toward drought.
Phys.org / Thirty years at El Mirón cave uncover 40,000 years of Iberian prehistory
For the past three decades, a team of archaeologists have been uncovering some of the field's most recent monumental discoveries, relying on gut instinct, persistent hard work, and cutting-edge methods and technologies.
Phys.org / First direct view tracks planet-forming disk spinning around AB Aurigae
The rotation of a protoplanetary disk (a disk where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains within it. The disk in question surrounds the ...
Phys.org / Student astronomer discovers 'Rosetta Stone' for mysterious cosmic signals
An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that ...
Phys.org / Trees and greenery can cool perceived heat in cities by as much as 18°C—but only if they're the right type
Cities around the world are planting more trees to cope with rising urban heat. But our research shows trees alone are often not enough. In some cases, the wrong kind of greening can even make streets feel less comfortable ...
