Published Unconventional interface superconductor could benefit quantum computing



A multi-institutional team of scientists has developed a new superconductor material that could potentially be used in quantum computing and be a candidate 'topological superconductor.'
Published Toward a code-breaking quantum computer



Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography.
Published Qubit coherence decay traced to thermal dissipation



Hitherto a mystery, the thermal energy loss of qubits can be explained with a surprisingly simple experimental setup, according to new research.
Published To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say



Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.
Published Fossil hotspots in Africa obscure a more complete picture of human evolution



A new study shows how the mismatch between where fossils are preserved and where humans likely lived may influence our understanding of early human evolution.
Published Scientists harness quantum microprocessor chips for revolutionary molecular spectroscopy simulation



Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules.
Published Tracking down the asteroid that sealed the fate of the dinosaurs



The asteroid that led to the extinction of the dinosaurs 66 million years ago probably came from the outer solar system.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth'



The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published Quantum pumping in molecular junctions



Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Advancing modular quantum information processing



A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published Giant fossil seeds from Borneo record ancient plant migration



Ancient fossil beans about the size of modern limes, and among the largest seeds in the fossil record, may provide new insight into the evolution of today's diverse Southeast Asian and Australian rainforests, according to researchers who identified the plants.
Published Millions of years for plants to recover from global warming



Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Achieving quantum memory in the hard X-ray range



Physicists have used Doppler-shifted nuclear resonant absorbers to form a nuclear frequency comb, enabling a quantum memory in the notoriously difficult X-ray range.
Published Early mammals lived longer



What distinguishes the growth and development patterns of early mammals of the Jurassic period? Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached maturity, by studying growth rings in fossilized tooth roots.
Published When mammoths roamed Vancouver Island



Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing



Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis



A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe



Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published Physicists develop new method to combine conventional internet with the quantum internet



Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time.
Published Fossil shows how penguins' wings evolved



A tiny fossil penguin plays a huge role in the evolutionary history of the bird, an international study shows.
