Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread



Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard



Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.
Published Visual explanations of machine learning models to estimate charge states in quantum dots



To form qubit states in semiconductor materials, it requires tuning for numerous parameters. But as the number of qubits increases, the amount of parameters also increases, thereby complicating this process. Now, researchers have automated this process, overcoming a significant barrier to realizing quantum computers.
Published Last surviving woolly mammoths were inbred but not doomed to extinction



The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic diversity but not to the extent that it can explain their ultimate (and mysterious) extinction.
Published Characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films



If there's one thing we humans are good at, it's producing heat. Significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, our factories, even our electrical grid.
Published Prehistoric 'Pompeii' discovered: Most pristine trilobite fossils ever found shake up scientific understanding of the long extinct group



Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and are being referred to by scientists as 'Pompeii' trilobites due to their remarkable preservation in ash.
Published Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds



We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
Published Understanding quantum states: New research shows importance of precise topography in solid neon qubits



A new study shows new insight into the quantum state that describes the condition of electrons on an electron-on-solid-neon quantum bit, information that can help engineers build this innovative technology.
Published A chip-scale Titanium-sapphire laser



With a single leap from tabletop to the microscale, engineers have produced the world's first practical Titanium-sapphire laser on a chip, democratizing a once-exclusive technology.
Published Precision instrument bolsters efforts to find elusive dark energy



Dark energy -- a mysterious force pushing the universe apart at an ever-increasing rate -- was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion. Physicists combined an optical lattice with an atom interferometer to hold atoms in place for up to 70 seconds -- a record for an atom interferometer -- allowing them to more precisely test for deviations from the accepted theory of gravity that could be caused by dark energy particles such as chameleons or symmetrons. Though they detected no anomalies, they're improving the experiment to perform more sensitive tests of gravity, including whether gravity is quantized.
Published Almonds, pottery, wood help date famed Kyrenia shipwreck



Researchers have identified the likeliest timeline of the famous Hellenistic-era Kyrenia shipwreck, discovered and recovered off the north coast of Cyprus in the 1960s.
Published Shocked quartz reveals evidence of historical cosmic airburst



Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.
Published Researchers discover new flat electronic bands, paving way for advanced quantum materials



Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
Published Study challenges popular idea that Easter islanders committed 'ecocide'



Some 1,000 years ago, a small band of Polynesians sailed thousands of miles across the Pacific to settle one of the world's most isolated places -- a small, previously uninhabited island they named Rapa Nui. Eventually, their numbers ballooned to unsustainable levels, they wrecked the environment, and their civilization collapsed. At least that is the longtime story, told in academic studies and popular books. A new study challenges this narrative of 'ecocide' saying that Rapa Nui's population never spiraled to unsustainable levels.
Published New study finds dinosaur fossils did not inspire the mythological griffin



For centuries, scientists thought they knew where the griffin legend came from. A new study takes a closer look at the data and folklore's influence on science.
Published Newly discovered dinosaur boasts big, blade-like horns



A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published New NOvA results add to mystery of neutrinos



The international collaboration presented their first results with new data in four years, featuring a new low-energy sample of electron neutrinos and a dataset doubled in size.
Published The world's oldest wine discovered



A white wine over 2,000 years old, of Andalusian origin, is the oldest wine ever discovered.
Published Breakthrough may clear major hurdle for quantum computers



The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published New material puts eco-friendly methanol conversion within reach



Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
