Phys.org / When only the strong shells survive: Archaeology's fresh approach to turn oyster shells into tools of conservation
We've feasted on them, built economies around them and in some places nearly erased them from our coasts. Today, 85% of the world's oyster reefs are gone. Many fisheries are collapsing, and those in Florida are no exception: ...
Phys.org / Genetics may influence our choice of academic field
What we choose to study—whether fine art or finance—is one of the most influential decisions in our lives. It shapes not only career trajectories, but also income, fertility, and well-being. As access to education is ...
Phys.org / AI assistant developed for every step of the scientific process
Researchers have developed an AI-powered 'scientific assistant' designed to accelerate the scientific process by helping them identify new research questions, analyze and interpret data, and produce scientific documents.
Phys.org / Pink sea anemone that 'builds a home' for hermit crabs discovered off Japan's deep-sea coast
Researchers from Kumamoto University and collaborating institutions have discovered a new species of deep-sea sea anemone that builds shell-like "homes" for hermit crabs—an extraordinary case of mutualism and co-evolution ...
Phys.org / Dynamics of Denisovan ancestry in Eurasians over the past 40,000 years revealed
Modern humans inherited part of their ancestry from multiple, genetically distinct Denisovan groups through interbreeding events. However, the history of contact with Denisovans remains unclear.
Phys.org / Scientists uncover key mechanisms that drive an enzyme linked to aging and cancer
Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the Institute of Science Tokyo reveal that a tandem allosteric effect of reactant and product is responsible ...
Phys.org / Physicists achieve high precision in measuring strontium atoms using rubidium neighbor
Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an important property of strontium atoms, a highly useful element for modern applications in atomic ...
Phys.org / Optimizing avalanche photodiode design for photodetection in the ultraviolet wavelength
Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate electron-hole pairs in a process ...
Phys.org / Lost or leading the way? Rare birds may signal shifting migration routes
On a 2009 hike in the Huachuca Mountains of southeastern Arizona, a group of birders heard an otherworldly, ethereal bird song floating, flute-like, through the canyon. The hikers identified the singer as a brown-backed solitaire, ...
Phys.org / Extremely massive stars forged oldest star clusters in the universe, model suggests
An international team led by ICREA researcher Mark Gieles, from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), has developed a model that reveals ...
Phys.org / Tiny, overlooked ponds in the Andes may play an outsized role in climate change
Small mountain ponds high in the tropical Andes may be playing an outsized role in global climate change, according to new research led by scientists at the University of North Carolina.
Phys.org / Infrared sensors gain sensitivity with ultra-thin lens for fire and threat monitoring
Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems.
