Published New conductive, cotton-based fiber developed for smart textiles



A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.
Published Non-invasive technology for the high-throughput characterization of cancer cells



The electrical properties of cancer cells can provide information on their cancer type, state, and drug resistance. However, conventional platforms to measure these properties are complex and can only analyze a few cells. Researchers have successfully developed a high-throughput device that measures the electrical properties of cancer cells through continuous flow electrorotation. The new platform offers a high degree of automation and can simultaneously analyze several cells.
Published Nanoparticle-delivered RNA reduces neuroinflammation in lab tests



In mice and human cell cultures, researchers showed that novel nanoparticles can deliver a potential therapy for inflammation in the brain, a prominent symptom in Alzheimer's disease.
Published Researchers combine biopolymers derived from the ocean to replace synthetic plastic films



Crustacean and seaweed materials combined in a unique way could provide a sustainable alternative to plastic films.
Published Conjoined 'racetracks' make new optical device possible



Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem.
Published Veins of bacteria could form a self-healing system for concrete infrastructure



In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been around since the first masons were mixing horsehair into their mud. But this research team is taking this method to the next level by turning reinforcing fibers into a living tissue system that rushes concrete-healing bacteria to the site of cracks to repair the damage.
Published Immersive VR goggles for mice unlock new potential for brain science



New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published First observation of structures resulting from 3D domain swapping in antibody light chains



Antibodies hold promise as therapeutic agents. However, their tendency to aggregate poses significant challenges to drug development. In a groundbreaking study, researchers now provide novel insights into the structure formed due to 3D domain swapping of the antibody light chain, the part of the antibody contributing to antigen binding. Their findings are expected to lead to improvements in antibody quality and the development of novel drugs.
Published Breakthrough nanobody technology against liver inflammation



Researchers have developed a technique based on nanobody technology to prevent liver inflammation. Nanobodies, or single-domain antibodies, are fragments of antibodies that can selectively bind to a specific antigen. Because they are simple to produce and react in very specific ways, they are often used in various biotechnological, therapeutic and diagnostic applications.
Published A fork in the 'rhod': Researchers unveil comprehensive collection of rhodamine-based fluorescent dyes



After more than a decade of developing fluorescent probes, a research team has now released the culmination of their years of work: A comprehensive collection of rhodamine-based dyes, the novel chemistry they developed to synthesize them and insights that provide a roadmap for designing future probes.
Published Training algorithm breaks barriers to deep physical neural networks



Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware.
Published Study: International scientists believe lack of women in physics tied to personal preference, but viewpoint ignores gender norms



Fewer women pursue careers in physics than biology, and scientists from around the world believe these differences come down to personal preferences, according to a new study of international scientists. The study's researchers warn that merely chalking this imbalance up to individual choice may diminish the push for gender equality in the sciences.
Published Chemists create organic molecules in a rainbow of colors



Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.
Published Artificial intelligence makes gripping more intuitive



Artificial hands can be operated via app or with sensors placed in the muscles of the forearm. New research shows: a better understanding of muscle activity patterns in the forearm supports a more intuitive and natural control of artificial limbs. This requires a network of 128 sensors and artificial intelligence based techniques.
Published From infamy to ingenuity: Bacterial hijack mechanisms as advanced genetic tools



Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in plants.
Published Exposure to soft robots decreases human fears about working with them



Seeing robots made with soft, flexible parts in action appears to lower people's anxiety about working with them or even being replaced by them. A study found that watching videos of a soft robot working with a person at picking and placing tasks lowered the viewers' safety concerns and feelings of job insecurity. This was true even when the soft robot was shown working in close proximity to the person. This finding shows soft robots hold a potential psychological advantage over rigid robots made of metal or other hard materials.
Published New wearable communication system offers potential to reduce digital health divide



Researchers developed a wearable device that can transmit health data 2,400 times the distance of Wi-Fi without significant network infrastructure.
Published Needle-free ultrasound vaccine delivery



Researchers are investigating the potential of a painless, needle-free vaccine delivery by ultrasound. The method uses cavitation, which is the formation and popping of bubbles in response to a sound wave. Though initial in vivo tests reported 700 times fewer vaccine molecules were delivered by the cavitation approach compared to conventional injection, the cavitation approach produced a higher immune response. The researchers theorize this could be due to the immune-rich skin the ultrasonic delivery targets. The result is a more efficient vaccine that could help reduce costs and increase efficacy.
Published Snail-inspired robot could scoop ocean microplastics



Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
Published Quantum physics: Superconducting Nanowires Detect Single Protein Ions



An international research team has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% quantum efficiency and exceed the detection efficiency of conventional ion detectors at low energies by a factor of up to a 1,000. In contrast to conventional detectors, they can also distinguish macromolecules by their impact energy. This allows for more sensitive detection of proteins and it provides additional information in mass spectrometry.
