| Sugar-coated nanoparticles target macrophages, reverse pulmonary fibrosis Posted: 05 Apr 2022 11:35 AM PDT Scientists have developed a treatment for pulmonary fibrosis by using nanoparticles coated in mannose -- a type of sugar -- to stop a population of lung cells called macrophages that contribute to lung tissue scarring. The cell-targeting method holds promise for preventing this severe lung scarring disease, which can result in life-threatening complications like shortness of breath. |
| 'Ears' for rover Perseverance's exploration of Mars Posted: 05 Apr 2022 09:39 AM PDT Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as well. |
| The relationship between active areas and boundaries with energy input in snapping shells Posted: 05 Apr 2022 08:52 AM PDT New research looks at how the geometry of shells relates to the energy input required to actuate snap-through instability. |
| Investigating newly synthesized thallium compounds for optoelectronic devices Posted: 05 Apr 2022 08:52 AM PDT The burgeoning field of optoelectronic devices is driving the development of new alkali metal-based chalcogenides with qualities that have to be robustly investigated. |
| Astrophysical plasma study benefits from new soft X-ray transition energies benchmark Posted: 05 Apr 2022 08:52 AM PDT The analysis of astrophysical plasmas is vital in the quest to learn about some of the Universe's most powerful and mysterious objects and events such as stellar coronae and winds, cataclysmic variables, X-ray binaries containing neutron stars and black holes, supernova remnants, or outflows in active galactic nuclei. The success of such research will lead to future astrophysical X-ray observatories enabling scientists to access techniques that are currently not available to X-ray astronomy. A key requirement for the accurate interpretation of high-resolution X-ray spectra is accurate knowledge of transition energies. |
| Solar cell keeps working long after sun sets Posted: 05 Apr 2022 08:52 AM PDT Researchers have constructed a photovoltaic cell that harvests energy from the environment during the day and night, making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperatures a few degrees below the ambient air. The device under development uses a thermoelectric module to generate voltage and current from the temperature gradient between the cell and the air. The setup is inexpensive and, in principle, could be incorporated within existing solar cells. |
| Scientists develop a recyclable pollen-based paper for repeated printing and ‘unprinting’ Posted: 05 Apr 2022 06:27 AM PDT Scientists have developed a pollen-based 'paper' that, after being printed on, can be 'erased' and reused multiple times without any damage to the paper. |
| Honey holds potential for making brain-like computer chips Posted: 05 Apr 2022 05:46 AM PDT Honey might be a sweet solution for developing environmentally friendly components for neuromorphic computers, systems designed to mimic the neurons and synapses found in the human brain. Hailed by some as the future of computing, neuromorphic systems are much faster and use much less power than traditional computers. Engineers have demonstrated one way to make them more organic too by using honey to make a memristor, a component similar to a transistor that can not only process but also store data in memory. They created the memristors by processing honey into a solid form and sandwiching it between two metal electrodes, making a structure similar to a human synapse. They then tested the honey memristors' ability to mimic the work of synapses with high switching on and off speeds of 100 and 500 nanoseconds respectively. The memristors also emulated the synapse functions known as spike-timing dependent plasticity and spike-rate dependent plasticity, which are responsible for learning processes in human brains and retaining new information in neurons. |
| New non-destructive DNA method opens opportunities Posted: 05 Apr 2022 05:45 AM PDT A new method of obtaining ancient genomic data without damaging source material has been developed, creating new opportunities for museum and archaeological collections worldwide. |
| ‘Freeze-thaw battery’ is adept at preserving its energy Posted: 05 Apr 2022 05:45 AM PDT Scientists have created a battery designed for the electric grid that locks in energy for months without losing much storage capacity. It's a step toward batteries that can be used for seasonal storage: saving renewable energy in one season, such as the spring, and spending it in another, like autumn. |
| Posted: 04 Apr 2022 12:01 PM PDT As the demand for home deliveries from online purchases continues to increase, researchers recently published research showing that some -- but not all -- consumers will accept going to alternate delivery locations to get their packages rather than having them delivered directly to their front door. |
| Solar hydrogen: Better photoelectrodes through flash heating Posted: 04 Apr 2022 09:05 AM PDT Producing low-cost metal-oxide thin films with high electronic quality for solar water splitting is not an easy task. Especially since quality improvements of the upper metal oxide thin films need thermal processing at high temperatures, which would melt the underlying glass substrate. Now, a team has solved this dilemma: A high intensity and rapid light pulse directly heats the semiconducting metal-oxide thin film, allowing it to reach the optimal temperature without damaging the substrate. |
| Dual-mode endoscope offers unprecedented insights into uterine health Posted: 04 Apr 2022 09:05 AM PDT A new endoscope design that combines ultrasound with optical coherence tomography can assess the structural features of the endometrium with unprecedented detail. This dual-mode endoscope could help doctors diagnose infertility problems that are related to endometrial receptivity with greater accuracy than current imaging technologies. |
| Chemical data management: an open way forward Posted: 04 Apr 2022 09:04 AM PDT Scientists propose an open platform for managing the vast amounts of diverse data produced in chemical research. |
| Making a ‘sandwich’ out of magnets and topological insulators, potential for lossless electronics Posted: 04 Apr 2022 07:57 AM PDT A research team has discovered that sandwiching a topological insulator between two 2D ferromagnetic insulators provides a quantum avenue towards ultra-low energy future electronics, or topological photovoltaics. |
| Using gene scissors to specifically eliminate individual cell types Posted: 04 Apr 2022 07:57 AM PDT With the help of the CRISPR/Cas molecular scissors, genetic information in a plant can be modified to make the latter more robust to pests, diseases, or extreme climatic conditions. Researchers have now developed this method further to eliminate the complete DNA of specific cell types and, thus, prevent their formation during plant development. This will also help researchers better understand development mechanisms in plants. |
| The material that could save industries heat Posted: 04 Apr 2022 07:57 AM PDT Scientists have found a common substance that can reversibly and rapidly store and release relatively large amounts of low-grade heat without decomposing.

| Understanding the use of bicycle sharing systems with statistics Posted: 04 Apr 2022 07:56 AM PDT Though bicycle sharing systems (BSSs) are popular in many big cities, it is necessary to actively rebalance the number of bicycles across the various ports with optimization algorithms. In a recent study, researchers statistically analyzed the bicycle usage patterns in four real-world BSSs to obtain realistic benchmarks for testing these algorithms. Their findings can make BSS rebalancing more efficient through an understanding of the social dynamics of human movement. |
| Posted: 04 Apr 2022 06:30 AM PDT Researchers have introduce a new path towards superior organic thermoelectric devices: highly efficient modulation doping of highly ordered organic semiconductors under high doping concentrations. |
| Quantum 'shock absorbers' allow perovskite to exhibit superfluorescence at room temperature Posted: 31 Mar 2022 12:15 PM PDT Semiconducting perovskites that exhibit superfluorescence at room temperature do so due to built-in thermal 'shock absorbers' which protect dipoles within the material from thermal interference. |
