Published Generating stable qubits at room temperature
(via sciencedaily.com) Original source Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.
Published First direct imaging of small noble gas clusters at room temperature
(via sciencedaily.com) Original source Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to this breakthrough was the confinement of noble gas atoms between two layers of graphene.
Published Discovery of immense fortifications dating back 4,000 years in north-western Arabia
(via sciencedaily.com) Original source The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis -- one of the longest known going back to this period -- was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia.
Published The extinction of the giant ape: Long-standing mystery solved
(via sciencedaily.com) Original source The largest ever primate Gigantopithecus blacki went extinct when other Asian great apes were thriving, and its demise has long been a mystery. A massive regional study of 22 caves in southern China explores a species on the brink of extinction between 295,000 and 215,000 years ago. As the environment became more seasonal, forest plant communities changed Primates such as orangutans adapted their eating habits and behaviors in response but G. blacki showed signs of stress, struggled to adapt and their numbers dwindled.
Published Epic of a molecular ion: With eyes of electrons
(via sciencedaily.com) Original source Researchers have achieved real-time capture of the ionization process and subsequent structural changes in gas-phase molecules through an enhanced mega-electronvolt ultrafast electron diffraction (MeV-UED) technique, enabling observation of faster and finer movements of ions.
Published Observing macroscopic quantum effects in the dark
(via sciencedaily.com) Original source Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.
Published How black silicon, a prized material used in solar cells, gets its dark, rough edge
(via sciencedaily.com) Original source Researchers have developed a new theoretical model explaining one way to make black silicon. The new etching model precisely explains how fluorine gas breaks certain bonds in the silicon more often than others, depending on the orientation of the bond at the surface. Black silicon is an important material used in solar cells, light sensors, antibacterial surfaces and many other applications.
Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com) Original source Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Nine new snail species discovered in Papua New Guinea, a biodiversity hot spot at risk
(via sciencedaily.com) Original source A new study describes nine new species of carnivorous land snails, all of which are so small they could fit together on a U.S. nickel. They present a rare opportunity to study a group that in many other places is disappearing fast. Worldwide, mollusks account for more than 50% of all recorded extinctions since the year 1500, and many of these were land snails from Pacific islands.
Published Cult mentality: Monumental discovery in Italy
(via sciencedaily.com) Original source Researchers have discovered an ancient Roman temple that adds significant insights into the social change from pagan gods to Christianity within the Roman Empire.
Published Using berry phase monopole engineering for high-temperature spintronic devices
(via sciencedaily.com) Original source Spin-orbit torque (SOT), an important phenomenon for developing ultrafast and low-power spintronic devices, can be enhanced through Berry phase monopole engineering at high temperatures. In a new study, the temperature dependence of the intrinsic spin Hall effect of TaSi2 was investigated. The results suggest that Berry phase monopole engineering is an effective strategy for achieving high-temperature SOT spintronic devices.
Published Researchers rely on Earth's magnetic field to verify an event mentioned in the Old Testament
(via sciencedaily.com) Original source A new study scientifically corroborates an event described in the Second Book of Kings -- the conquest of the Philistine city of Gath by Hazael King of Aram. The method is based on measuring the magnetic field recorded in burnt bricks. The researchers say that the findings are important for determining the intensity of the fire and the scope of destruction in Gath, and also for understanding construction practices in the region.
