Published Golden rules for building atomic blocks


Physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter.
Published New approach to fighting malaria



Findings can open up new avenues for targeted approaches toward therapeutic strategies against the malaria-causing P. falciparum that are aimed at stopping the parasite's life cycle progression and its sexual differentiation, thus blocking the transmission of the parasite into mosquitoes.
Published Quantum computer unveils atomic dynamics of light-sensitive molecules


Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
Published Which radio waves disrupt the magnetic sense in migratory birds?


Many songbirds use the earth's magnetic field as a guide during their migrations, but radiowaves interfere with this ability. A new study has found an upper bound for the frequency that disrupts the magnetic compass.
Published Making the invisible, visible: New method makes mid-infrared light detectable at room temperature


Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.
Published Scientists use quantum device to slow down simulated chemical reaction 100 billion times


Using a trapped-ion quantum computer, the research team witnessed the interference pattern of a single atom caused by a 'conical intersection'. Conical intersections are known throughout chemistry and are vital to rapid photo-chemical processes such as light harvesting in human vision or photosynthesis.
Published Unlocking the secrets of cell antennas



The NSL (non-specific lethal) complex regulates thousands of genes in fruit flies and mammals. Silencing the NSL genes leads to the death of the organism, which gave the complex its curious name. Researchers have now discovered that the genes regulated by the NSL complex also include genes of the intraciliary transport system. This enables different cell types to form cilia on their surface, which are important for cell communication. The study shows that these genes are 'switched on' by the NSL complex, regardless of whether a particular cell has cilia or not. The researchers found that this class of cilia-associated genes is crucial for the function of podocytes. This is a highly specialized cell type of the kidney that, paradoxically, does not have cilia. These findings have important implications for ciliopathies and kidney disease.
Published New quantum device generates single photons and encodes information


A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published Researchers describe rebuilding, regenerating lung cells



Researchers have discovered a novel approach for engrafting engineered cells into injured lung tissue. These findings may lead to new ways for treating lung diseases, such as emphysema, pulmonary fibrosis and COVID-19. The two studies describe the methodologies for engineering lung stem cells and transplanting them into injured experimental lungs without immunosuppression.
Published The 'treadmill conveyor belt' ensuring proper cell division



Researchers have discovered how proteins work in tandem to regulate 'treadmilling', a mechanism used by the network of microtubules inside cells to ensure proper cell division.
Published Do measurements produce the reality they show us?


The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published Researchers target lifecycle of parasite behind Chagas disease



Researchers are studying the signaling pathway that leads the parasite responsible for Chagas disease to transform and reproduce. They follow that pathway from the beginning when an uninfected kissing bug acquires the parasite by biting an infected mammal host all the way to the time the parasite develops in the insect's gut to be spread to people or animals through the bug's poop.
Published Researchers unearth a new process by which algae pass on nurtrients to their coral host


Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Research group detects a quantum entanglement wave for the first time using real-space measurements


A team has created an artificial quantum magnet featuring a quasiparticle made of entangled electrons, the triplon.
Published Scientists develop fermionic quantum processor


Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published High-fat diets alter gut bacteria, boosting colorectal cancer risk in mice



Researchers have discovered how high-fat diets can change gut bacteria and alter digestive molecules called bile acids that are modified by those bacteria, predisposing mice to colorectal cancer. The findings bring scientists closer to understanding the causes of and how to prevent colorectal cancer.
Published Want to know how light works? Try asking a mechanic


Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves.
Published Research team developing a nano-sized force sensor and improving high-precision microscopy technology


Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.
Published 'Viral relicts' in the genome could fuel neurodegeneration



Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers come to this conclusion on the basis of studies on cell cultures.
Published Ancient metal cauldrons give us clues about what people ate in the Bronze Age



Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).
