Phys.org / Cracking a 16-year proton mystery as ultra-precise hydrogen measurements confirm a smaller-than-expected core
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...
Phys.org / In Arizona's desert, tiny ants turn into living hygienists, climbing inside bigger ants' mandibles and cleaning them
Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.
Phys.org / 'Ghost tunnels' guide sound waves in one direction while staying invisible to others
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, ...
Phys.org / A new fruit wash removes pesticides and extends shelf life
University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and ...
Phys.org / Revived Nubian royal robes shed light on prestige and authority in a lost Christian kingdom
A recent archaeological project has physically reconstructed the ceremonial dress of medieval Nubian royalty and clergy, offering a rare glimpse into how clothing shaped and communicated authority in Christian Nubia. The ...
Phys.org / Powerful imaging pulls lost ocean life from 445-million-year-old stone and exposes a hidden extinction record
New technology has helped a team of scientists uncover more than 20 microscopic fossils, including a species previously unknown to science. The discovery may provide us with fresh insights into the Late Ordovician, one of ...
Phys.org / Mount Etna breaks volcano rules, tapping 80-kilometer-deep magma in a rare fourth category of eruption
Located in Sicily, Mount Etna is Europe's most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from the University of Lausanne ...
Phys.org / The sun is tearing an asteroid to pieces, and Earth is now flying through the fallout
Across Earth, every night, thousands of automated stargazers are waiting to take pictures of shooting stars. I am one of the scientists who study these meteors.
Phys.org / Lost seal of Edward the Confessor resurfaces after going missing for 40 years
An 11th-century Anglo-Saxon seal belonging to Edward the Confessor has been rediscovered more than 40 years after being declared lost. The wax impression of the "Saint-Denis seal" disappeared without official explanation ...
Phys.org / Date palm waste yields bio-oil, unlocking energy use for 150 million trees
Researchers have developed a method to extract bio-oil from the surface fiber waste of date palm trees, an abundant, low-cost, and sustainable biomass resource generated by an estimated 150 million date palm trees worldwide. ...
Phys.org / Low-cost robotic chemistry system can be built and deployed in any lab
In a paper just out in Nature Synthesis, researchers led by Prof. Timothy Noël of the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences presented a breakthrough in autonomous laboratory systems for synthesis ...
Phys.org / Ultrasound creates light inside the body, opening a new path to targeted treatments
Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers—but it doesn't easily pass through tissue. Most methods to ...
