Large-scale optical programmable logic array can execute complex models like Conway’s Game of Life, marking a significant advancement in optical computing. Researchers have long sought to harness the power of light for computing, aiming to achieve higher speeds and lower energy consumption compared to traditional electronic systems. Optical computing, which uses light instead of electricity to perform calculations, promises significant advantages, including high parallelism and efficiency. However, implementing complex logic operations optically has been a challenge, limiting the practical applications…
UCLA researchers developed unidirectional imaging technology, a crucial capability for applications requiring asymmetric visual information processing and optical communication. Traditional imaging systems are bidirectional—if I can see you, you can also see me. Researchers at UCLA recently developed a new type of imaging technology that could revolutionize how we capture and process visual information: unidirectional imaging. By allowing images to be formed in only one direction, this technology provides an efficient and compact method for asymmetric visual information processing and…
The combination of phototherapy and chemotherapy could offer a more effective way to fight aggressive tumors. Patients with late-stage cancer often have to endure multiple rounds of different types of treatment, which can cause unwanted side effects and may not always help. In hopes of expanding the treatment options for those patients, MIT researchers have designed tiny particles that can be implanted at a tumor site, where they deliver two types of therapy: heat and chemotherapy. This approach could avoid…
University of Texas at Dallas mechanical engineers have designed a 3D-printed femur that could help doctors prepare for surgeries to repair bones and develop treatments for bone tumors. The engineers, who worked in collaboration with UT Southwestern Medical Center orthopedic surgeons, published their first study on the 3D-printed thigh bone online Aug. 5 in the Journal of Orthopaedic Research. The study, which focused on the middle section of the bone, establishes 3D-printing parameters for a femur for use in biomechanical…
Ultrasound, once used almost exclusively to take images of the body, is quickly developing into a targeted therapy that can have a potentially life-changing impact on our brains, according to the authors of a new article. For decades, health professionals across the world have used ultrasound as a means of monitoring the development of unborn babies and assessing the health of patients’ internal organs. But writing in the journal PLOS Biology, researchers from Stanford University, the University of Plymouth, and…
Small drops, big impact: Over time, rain can damage the surfaces of rotor blades. This reduces the efficiency and profitability of wind turbines, especially at sea. Researchers from institutions of the U Bremen Research Alliance are developing repair solutions to extend the service life of rotor blades. Picture a large shower cubicle and you are not far off the test bench at the Fraunhofer Institute for Wind Energy Systems IWES in Bremerhaven. The only difference is that the water comes…
Researchers from Bonn uncover how tiny eye movements and the density of our photoreceptors aid in sharp vision Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details. The density of these cells varies from person to person. Additionally, when we fixate on an object, our eyes make subtle, continuous movements,…
… revolutionizes the diagnosis of head and neck tumors. Head and neck cancers are among the ten most common cancers worldwide. Head and neck tumors account for about 3-5% of all cancers, with squamous cell carcinomas being the predominant form. They occur in areas such as the oral cavity, pharynx and larynx. An international team of researchers led by Sara Wickström has now developed a new technique that allows the properties of cancer cells and their surrounding tissue to be…
…offers new hope in the fight against bacterial infections. Researchers at the University of Chicago and the University of California San Diego have made an exciting breakthrough in the battle against bacterial infections. The Bozhi Tian (UChicago) and Gürol Süel (UC San Diego) labs have developed a cutting-edge bioelectronic device that taps into the natural electrical activity of certain bacteria found on our skin, paving the way for a drug-free approach to managing infections. This groundbreaking study, published in DEVICE, reveals how programmable electrical…
Roughly one third of patients with depressive symptoms have elevated levels of inflammation. Inflammation is however often only measured using very broad and unspecific markers. To better understand the connection between depression and the immune system, researchers at the Max Planck Institute of Psychiatry measured a large amount of different biological factors and identified patterns in the data. In the newly published study, first author Jonas Hagenberg and scientists from the Project Group Medical Genomics, led by Janine Knauer-Arloth, measured…
In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not be disturbed along the way, hypersensitive receivers and noise-free amplifiers are required. Now, researchers at Chalmers University of Technology, in Sweden, have created a system that, with a silent amplifier and record-sensitive receiver, paves the way for faster and improved space communication. Space communication…
…takes sensor technology to extreme conditions. Researchers at Tampere University have developed the world’s first soft touchpad that can sense the force, area and location of contact without electricity. The device utilises pneumatic channels, enabling its use in environments such as MRI machines and other conditions that are unsuitable for electronic devices. Soft devices like soft robots and rehabilitation aids could also benefit from this new technology. Researchers at Tampere University have developed the world’s first soft touchpad that is…
New methods enable complex calculations to be completed extremely quickly. For the first time ever, scientists at Paderborn University have used high-performance computing (HPC) at large scales to analyse a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a quantum detector. This is a device that measures individual photons, i.e. light particles. The researchers involved developed new HPC software to achieve this. Their findings have now been published in the specialist journal ‘Quantum…
… in thunderstorm cloud-top corona discharges. A team of researchers from the University of Science and Technology of China (USTC), led by Professors LEI Jiuhou, ZHU Baoyou, and Associate Professor LIU Feifan, has made significant strides in understanding the mechanisms behind corona discharges at thunderstorm cloud tops, a phenomenon that plays a critical role in the Earth’s atmospheric chemistry. Their findings, published in the prestigious journal Nature Communications on August 26, introduce a new conceptual model that could reshape our…
Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance and helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft. “These flaps can both help the plane avoid stall and make it easier to regain control when stall does occur,” said Aimy Wissa, assistant professor of mechanical and aerospace engineering and principal investigator of the study, published in the Proceedings of the National…
A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies. Extracellular vesicles (EVs) are small ‘delivery trucks’ released by our cells that deliver important materials to other cells to aid cellular communication. This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia. Researchers hope to leverage the…
