Published New quantum sensing technique reveals magnetic connections


A research team demonstrates a new way to use quantum sensors to tease out relationships between microscopic magnetic fields.
Published Climate: Lessons from the latest global warming


56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming. This episode saw global temperatures rise by 5-8°C. It was marked by an increase in the seasonality of rainfalls, which led to the movement of large quantities of clay into the ocean, making it uninhabitable for certain living species. This scenario could be repeated today.
Published Engineers discover a new way to control atomic nuclei as 'qubits'


Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors.
Published Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon


Tenacity has taken a roadblock and turned it into a possible route to the development of quantum computing.
Published Securing supply chains with quantum computing


New research in quantum computing is moving science closer to being able to overcome supply-chain challenges and restore global security during future periods of unrest.
Published When the light is neither 'on' nor 'off' in the nanoworld


Scientists detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
Published Oldest spinosaur brains revealed


Researchers have reconstructed the brains and inner ears of two British spinosaurs, helping uncover how these large predatory dinosaurs interacted with their environment.
Published Researchers solve a 150-year-old mystery: Aetosaur find involves juveniles


Aetosaurs had a small head and a crocodile-like body. The land dwellers were up to six meters long and widely distributed geographically. They died out about 204 million years ago, at the end of the Triassic. In Germany, an assemblage of 24 Aetosaurus ferratus individuals, only between 20 and 82 centimeters long, was discovered in 1877. Since then, scientists have been puzzling over whether they were juveniles or small adults. A team has now solved the mystery: Bone examination of two specimens shows that they are juveniles.
Published Researchers detail never-before-seen properties in a family of superconducting Kagome metals


Researchers have used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of Kagome superconductor RbV3Sb5 at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.
Published Record low sea ice cover in the Antarctic



There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometers of the Southern Ocean were covered with sea ice.
Published Fossil discovery reveals complex ecosystems existed on Earth much earlier than previously thought



About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers.
Published 2.9-million-year-old butchery site reopens case of who made first stone tools


Along the shores of Africa's Lake Victoria in Kenya roughly 2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, according to new research. The study presents what are likely to be the oldest examples of a hugely important stone-age innovation known to scientists as the Oldowan toolkit, as well as the oldest evidence of hominins consuming very large animals. Excavations at the site, named Nyayanga and located on the Homa Peninsula in western Kenya, also produced a pair of massive molars belonging to the human species' close evolutionary relative Paranthropus. The teeth are the oldest fossilized Paranthropus remains yet found, and their presence at a site loaded with stone tools raises intriguing questions about which human ancestor made those tools.
Published Scientists boost quantum signals while reducing noise


Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
Published Scientists develop new index based on functional morphology to understand how ancestors of modern birds used their wings


Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such as the Pteranodon.
Published Distortion-free forms of structured light


Research offers a new approach to studying complex light in complex systems, such as transporting classical and quantum light through optical fiber, underwater channels, living tissue and other highly aberrated systems.
Published Scientists make major breakthrough in developing practical quantum computers that can solve big challenges of our time


Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
Published A fossil fruit from California shows ancestors of coffee and potatoes survived cataclysm that killed the dinosaurs



The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple crops like coffee, tomatoes, potatoes and mint.
Published Changing climate conditions likely facilitated early human migration to the Americas at key intervals, research suggests



Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.
Published Entangled atoms cross quantum network from one lab to another


Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
Published Researchers devise a new path toward 'quantum light'


Researchers have theorized a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale.
