Published Spin qubits go trampolining



Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published Research sheds light on the role of PTPRK in tissue repair and cancer



New research has advanced our knowledge of multiple roles for PTPRK, a receptor tyrosine phosphatase linked to the regulation of cell-cell adhesion, growth factor signalling and tumor suppression. Through a characterization of the function of PTPRK in human cell lines and mice, the team distinguished catalytic and non-catalytic functions of PTPRK. The findings extend what is known about the signalling mechanisms involving PTPRK as a phosphatase and its role in colorectal health but also shed new light on the extent of its function via non-catalytic signalling mechanisms.
Published Under pressure: How cells respond to physical stress



Cell membranes play a crucial role in maintaining the integrity and functionality of cells. However, the mechanisms by which they perform these roles are not yet fully understood. Scientists have used cryo-electron microscopy to observe how lipids and proteins at the plasma membrane interact and react to mechanical stress. This work shows that, depending on conditions, small membrane regions can stabilize various lipids to trigger specific cellular responses. These discoveries confirm the existence of well-organized lipid domains and begin to reveal the role they play in cell survival.
Published New video test for Parkinson's uses AI to track how the disease is progressing



An automated assessment technique that uses artificial intelligence could revolutionize the management of Parkinson's disease.
Published Dual action antibiotic could make bacterial resistance nearly impossible



New drug that disrupts two cellular targets would make it much harder for bacteria to evolve resistance.
Published New rapid method for determining virus infectivity



A new method that can rapidly determine whether a virus is infectious or non-infectious could revolutionize the response to future pandemics, researchers report.
Published Fruit fly post-mating behavior controlled by male-derived peptide via command neurons, study finds



Scientists have succeeded in pinpointing the neurons within a female fruit fly's brain that respond to signals from the male during mating.
Published Exposing dengue's invasion strategies



Mosquito-borne viral infections once confined to tropical regions are spreading. Dengue virus infects up to 400 million people worldwide each year according to World Health Organization estimates, and no available treatments exist for this disease. Now, research uncovered surprising strategies for how dengue and hundreds of other viruses replicate in their hosts, with the potential to aid in developing novel antiviral treatments and vaccines.
Published Not everything that tastes bitter is potentially harmful: But why? Study provides an explanation



A bitter taste is traditionally considered a warning sign of potentially toxic substances. But not all bitter substances are harmful. For example, some peptides and free amino acids taste bitter, even though they are non-toxic, nutritious and sometimes even vital for humans. A new study now offers an explanation for this seemingly paradoxical phenomenon.
Published Are AI-chatbots suitable for hospitals?



Large language models may pass medical exams with flying colors but using them for diagnoses would currently be grossly negligent. Medical chatbots make hasty diagnoses, do not adhere to guidelines, and would put patients' lives at risk. A team has systematically investigated whether this form of artificial intelligence (AI) would be suitable for everyday clinical practice. Despite the current shortcomings, the researchers see potential in the technology. They have published a method that can be used to test the reliability of future medical chatbots.
Published Transient structure in fly leg holds clue to insect shape formation



A little leg may reveal something big about how closely related insect species can drastically differ in body shape, according to a new study. The team imaged live cells of fruit flies in the last stages of development over several days and found a new structure that appears to help guide a section of the leg into its final shape.
Published Scientists use AI to predict a wildfire's next move



Researchers have developed a new model that combines generative AI and satellite data to accurately forecast wildfire spread.
Published Revolutionizing the abilities of adaptive radar with AI



Engineers have shown that using a type of AI that revolutionized computer vision can greatly enhance modern adaptive radar systems. And in a move that parallels the impetus of the computer vision boom, they have released a large dataset of digital landscapes for others to build on their work.
Published Can consciousness exist in a computer simulation?



A new essay explores which conditions must be met for consciousness to exist. At least one of them can't be found in a computer.
Published Want privacy? You're just a stick figure to this camera



A new camera could prevent companies from collecting embarrassing and identifiable photos and videos from devices like smart home cameras and robotic vacuums. It's called PrivacyLens.
Published Secrets behind viral precision



New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.
Published Does the type of workstation you use make a difference in your health and productivity?



Although devices such as standing desks have been found to alleviate physical symptoms and increase worker productivity, questions remain regarding the best use of the primary types of workstations -- stand-biased, sit-stand or traditional -- for increasing workers' physical activity and preventing health problems. To answer these questions, researchers measured the computer usage and activity levels of 61 office workers for 10 days to evaluate any discomfort and develop possible remedies.
Published Ant insights lead to robot navigation breakthrough



Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
Published Paleolithic diets are not without risks



High-protein diets, known as 'Paleolithic diets', are popular. Using mouse models, scientists have studied their impact. While effective in regulating weight and stabilizing diabetes, these diets are not without risks. Excess protein greatly increases ammonium production, overwhelming the liver. Excess ammonium can cause neurological disorders and, in severe cases, lead to coma. These results suggest caution when following these diets.
Published Paving the way to extremely fast, compact computer memory



Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
