Published Can pigeons match wits with artificial intelligence?
(via sciencedaily.com) Can a pigeon match wits with artificial intelligence? Researchers tested pigeons' learning abilities and concluded the birds employ the same basic process, called associative learning, as the most advanced AI technologies.
Published Passive radiative cooling can now be controlled electrically
(via sciencedaily.com) Energy-efficient ways of cooling buildings and vehicles will be required in a changing climate. Researchers have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure.
Published New approach to 'punishment and reward' method of training artificial intelligence offers potential key to unlock new treatments for aggressive cancers
(via sciencedaily.com) A new 'outside-the-box' method of teaching artificial intelligence (AI) models to make decisions could provide hope for finding new therapeutic methods for cancer, according to a new study.
Published To know where the birds are going, researchers turn to citizen science and machine learning
(via sciencedaily.com) Computer scientists recently announced a new, predictive model that is capable of accurately forecasting where a migratory bird will go next -- one of the most difficult tasks in biology. The model is called BirdFlow, and while it is still being perfected, it should be available to scientists within the year and will eventually make its way to the general public.
Published Smart stitches could reduce infection and simplify post op monitoring
(via sciencedaily.com) A new antimicrobial suture material that glows in medical imaging could provide a promising alternative for mesh implants and internal stitches.
Published Researchers take a step toward novel quantum simulators
(via sciencedaily.com) If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Published Transforming the way cancer vaccines are designed and made
(via sciencedaily.com) A new way to significantly increase the potency of almost any vaccine has been developed. The scientists used chemistry and nanotechnology to change the structural location of adjuvants and antigens on and within a nanoscale vaccine, greatly increasing vaccine performance in seven different types of cancer. The architecture is critical to vaccine effectiveness, the study shows.
Published Artificial intelligence aids discovery of super tight-binding antibodies
(via sciencedaily.com) Scientists developed an artificial intelligence tool that could accelerate the development of new high affinity antibody drugs.
Published This groundbreaking biomaterial heals tissues from the inside out
(via sciencedaily.com) A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.
Published New method to control electron spin paves the way for efficient quantum computers
(via sciencedaily.com) Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.
Published Will machine learning help us find extraterrestrial life?
(via sciencedaily.com) Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.
Published Quantum physicists make major nanoscopic advance
(via sciencedaily.com) Original source In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Published Researchers demo new type of carbon nanotube yarn that harvests mechanical energy
(via sciencedaily.com) Nanotechnology researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters.
Published Transistors repurposed as microchip 'clock' address supply chain weakness
(via sciencedaily.com) A new technique uses standard chip fab methods to fabricate the building block of a timing device, critical to all microprocessors. Currently, this timing device, known as an acoustic resonator, must be produced separately, often overseas, creating a supply chain and security weakness. The technique would allow for this timing device to be integrated with the microprocessor using standard CMOS processing, rather than later bunded with the microprocessor.
Published Color images from the shadow of a sample
(via sciencedaily.com) A research team has developed a new method to produce X-ray images in color. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole sample. This is time-consuming and expensive. Scientists have now developed an approach that allows an image of a large area to be produced from a single exposure, without the need for focusing and scanning.
Published Spin transport measured through molecular films now long enough to develop spintronic devices
(via sciencedaily.com) Original source A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
Published First computational reconstruction of a virus in its biological entirety
(via sciencedaily.com) A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.
Published Incorporation of water molecules into layered materials impacts ion storage capability
(via sciencedaily.com) Researchers have experimentally detected the structural change of hydration water confined in the tiny nano-scale pores of layered materials such as clays. Their findings potentially open the door to new options for ion separation and energy storage.
Published 'Smart' walking stick could help visually impaired with groceries, finding a seat
(via sciencedaily.com) For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.
