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 High-pressure spectroscopy: Why 3,000 bars are needed to take a comprehensive look at a protein
(via sciencedaily.com) Original source Why 3,000 bars are needed to take a comprehensive look at a protein: Researchers present a new high-pressure spectroscopy method to unravel the properties of proteins' native structures.
Published Improved nutrition, sanitation linked to beneficial changes in child stress and epigenetic programming
(via sciencedaily.com) Original source A new study provides some of the clearest and most comprehensive evidence to date on what is known about stress physiology and 'epigenetic programming.'
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 Aligned peptide 'noodles' could enable lab-grown biological tissues
(via sciencedaily.com) Original source Researchers have developed peptide-based hydrogels that mimic the aligned structure of muscle and nerve tissues, which could enable the development of functional lab-grown tissue.
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 Genomes of 'star algae' shed light on origin of plants
(via sciencedaily.com) Original source Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
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 How E. coli get the power to cause urinary tract infections
(via sciencedaily.com) Original source New research examines how the bacteria Escherichia coli, or E. coli -- responsible for most UTIs -- is able to use host nutrients to reproduce at an extraordinarily rapid pace during infection despite the near sterile environment of fresh urine.
Published Plants utilize drought stress hormone to block snacking spider mites
(via sciencedaily.com) Original source Recent findings that plants employ a drought-survival mechanism to also defend against nutrient-sucking pests could inform future crop breeding programs aimed at achieving better broadscale pest control.
Published Source of pregnancy complications from infections revealed by placenta map
(via sciencedaily.com) Original source The placenta's response to infections from malaria, toxoplasmosis and listeria has been mapped in high resolution, possibly paving the way for new treatment options.
Published New discovery of a mechanism that controls cell division
(via sciencedaily.com) Original source Researchers have discovered that how a special protein complex called the Mediator moves along genes in DNA may have an impact on how cells divide. The discovery may be important for future research into the treatment of certain diseases.
Published Novel chemical tool for understanding membrane remodeling in the cell
(via sciencedaily.com) Original source Researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell. The findings lead to a deeper understanding of how membrane remodeling works in human cells and future development of new drugs.
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 For microscopic organisms, ocean currents act as 'expressway' to deeper depths
(via sciencedaily.com) Original source Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Scientists track 'doubling' in origin of cancer cells
(via sciencedaily.com) Original source Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.
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 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 Deeper understanding of malaria parasite development unlocks opportunities to block disease spread
(via sciencedaily.com) Original source Natural malaria infections have been genetically analysed at a higher resolution than ever before, giving insights that could help understand and block transmission.
