Published Experiment opens door for millions of qubits on one chip
(via sciencedaily.com) Original source Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
Published AI to make crop production more sustainable
(via sciencedaily.com) Original source Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. Researchers are working on driving forward the smart digitalization of agriculture and have now published a list of the research questions that will need to be tackled as a priority in the future.
Published New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
(via sciencedaily.com) Original source Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Sister cities can help communities better navigate the climate crisis
(via sciencedaily.com) Original source Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
Published When injecting pure spin into chiral materials, direction matters
(via sciencedaily.com) Original source The direction in which spin information is injected into chiral materials affects its ability to pass through them. These chiral 'gateways' could be used to design energy-efficient spintronic devices for data storage, communication and computing.
Published Tweaking isotopes sheds light on promising approach to engineer semiconductors
(via sciencedaily.com) Original source Scientists have demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors.
Published Climate change amplifies severity of combined wind-rain extremes over the UK and Ireland
(via sciencedaily.com) Original source Climate change will cause an increase in extreme winter storms combining strong winds and heavy rainfall over the UK and Ireland, new research has shown.
Published New Nevada experiments will improve monitoring of nuclear explosions
(via sciencedaily.com) Original source On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published Physicists arrange atoms in extremely close proximity
(via sciencedaily.com) Original source Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.
Published Cost-effective, high-capacity, and cyclable lithium-ion battery cathodes
(via sciencedaily.com) Original source Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published Scientists test for quantum nature of gravity
(via sciencedaily.com) Original source A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep into the Antarctic glacier at the south pole.
Published Significant new discovery in teleportation research -- Noise can improve the quality of quantum teleportation
(via sciencedaily.com) Original source Researchers succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state.
Published New sensor detects errors in MRI scans
(via sciencedaily.com) Original source A new prototype sensor is capable of detecting errors in MRI scans using laser light and gas. The new sensor can thereby do what is impossible for current electrical sensors -- and hopefully pave the way for MRI scans that are better, cheaper and faster.
Published The big quantum chill: Scientists modify common lab refrigerator to cool faster with less energy
(via sciencedaily.com) Original source Scientists have dramatically reduced the time and energy required to chill materials to temperatures near absolute zero. Their prototype refrigerator could prove a boon for the burgeoning quantum industry, which widely uses ultracold materials.
Published Researchers unlock potential of 2D magnetic devices for future computing
(via sciencedaily.com) Original source A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.
Published Astronomers' simulations support dark matter theory
(via sciencedaily.com) Original source Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.
Published Details of hurricane Ian's aftermath captured with new remote sensing method
(via sciencedaily.com) Original source Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.
Published Atomic nucleus excited with laser: a breakthrough after decades
(via sciencedaily.com) Original source For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
Published Physicists show that light can generate electricity even in translucent materials
(via sciencedaily.com) Original source Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.
