Published Modern behavior explains prehistoric economies



What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
Published Bright prospects for engineering quantum light



Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?
Published Researchers develop general framework for designing quantum sensors



Researchers have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.
Published Researchers trap atoms, forcing them to serve as photonic transistors



Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Published Optical fibers fit for the age of quantum computing



A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published The ancestor of all modern birds probably had iridescent feathers



Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Folded peptides are more electrically conductive than unfolded peptides



What puts the electronic pep in peptides? A folded structure, according to a new study. Researchers combined single-molecule experiments, molecular dynamics simulations and quantum mechanics to validate the findings.
Published 'Kink state' control may provide pathway to quantum electronics



The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
Published Quantum sensor for the atomic world



In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Spin qubits go trampolining



Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published New snake discovery rewrites history, points to North America's role in snake evolution



A new species of fossil snake unearthed in Wyoming is rewriting our understanding of snake evolution. The discovery, based on four remarkably well-preserved specimens found curled together in a burrow, reveals a new species named Hibernophis breithaupti. This snake lived in North America 34 million years ago and sheds light on the origin and diversification of boas and pythons.
Published Human occupation in southeast Indonesia dating back 42,000 years



Evidence of human occupation in southeast Indonesia dating back 42,000 years offers fresh clues on the route taken by some of the first humans to arrive in our region, according to a new study.
Published Evidence for butchery of giant armadillo-like mammals in Argentina 21,000 years ago



Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a new study.
Published Ancient microbes offer clues to how complex life evolved



Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts.
Published Insight into one of life's earliest ancestors revealed in new study



Researchers have shed light on Earth's earliest ecosystem, showing that within a few hundred million years of planetary formation, life on Earth was already flourishing.
Published 'A history of contact': Geneticists are rewriting the narrative of Neanderthals and other ancient humans



Using genomes from 2,000 living humans as well as three Neanderthals and one Denisovan, an international team mapped the gene flow between the hominin groups over the past quarter-million years.
Published Unveiling 1,200 years of human occupation in Canada's Arctic



A recent study provides new insights into ancient cultures in Canada's Arctic, focusing on Paleo-Inuit and Thule-Inuit peoples over thousands of years. Researchers detected human presence and settlements on Somerset Island, Nunavut, by analyzing sediment samples.
Published First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin



An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth -- the first time such a feat has been achieved for any ancient DNA sample. The fossilized chromosomes, which are around a million times longer than most ancient DNA fragments, provide insight into how the mammoth's genome was organized within its living cells and which genes were active within the skin tissue from which the DNA was extracted. This unprecedented level of structural detail was retained because the mammoth underwent freeze-drying shortly after it died, which meant that its DNA was preserved in a glass-like state.
Published A breakthrough on the edge: One step closer to topological quantum computing



Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.
Published The plague may have caused the downfall of the Stone Age farmers



Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
