| Fiber tracking method delivers important new insights into turbulence Posted: 17 Sep 2021 09:20 AM PDT A new technique for measuring turbulent flows has been developed. By using fibers rather than particles -- the usual method of measurement -- the researchers could get a more detailed picture of turbulent flows. |
| Researchers improve optical tissue clearing method to diagnose cancer Posted: 16 Sep 2021 02:34 PM PDT The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly remove fats from tissues, which are a factor in tissue opacification, without losing their structure. The material is used in several biomedical devices, including contact lenses. |
| Discovery of liquid directional steering on a bio-inspired surface Posted: 16 Sep 2021 11:28 AM PDT Inspired by a kind of tree leaf, scientists discovered that the spreading direction of different liquids deposited on the same surface can be steered, solving a challenge that has remained for over two centuries. This breakthrough could ignite a new wave of using 3D surface structures for intelligent liquid manipulation with profound implications for various scientific and industrial applications, such as fluidics design and heat transfer enhancement. |
| The first glimpse of hydrodynamic electron flow in 3D materials Posted: 16 Sep 2021 11:28 AM PDT A team of researchers has developed a theory to explain how hydrodynamic electron flow could occur in 3D materials and observed it for the first time using a new imaging technique. |
| Finding new alloys just became simpler Posted: 16 Sep 2021 11:27 AM PDT In metal alloys, behavior at the atomic scale affects the material's properties. However, the number of possible alloys is astronomical. Scientists developed a theoretical model that allows him to rapidly determine the strength of millions of different alloys at high temperatures. |
| Microneedles pierce biofilm for more effective topical delivery of antibiotics to infected wounds Posted: 16 Sep 2021 10:13 AM PDT An engineer has developed a microneedle array that punctures biofilm covering ulcerated cells and tissues. The needles deliver antibiotics to the wounds by absorbing liquid underneath the biofilm and then dissolving. |
| Pyrrole chemistry: Good things come in threes Posted: 16 Sep 2021 08:46 AM PDT A new approach leads to the long-awaited formation of rings made of three pyrroles, which could be used to produce compounds with a host of interesting properties, and explains why they have not been observed before. |
| New technology makes it possible to see clearly through murky water Posted: 16 Sep 2021 08:46 AM PDT Researchers overcome the limitations of traditional polarimetric underwater imaging by developing a new method that can automatically produce clear images through murky water. The new technology could be useful for searching for drowning victims, documenting submerged archaeological artifacts and monitoring underwater farms. |
| PFAS exposure can affect women’s ability to breastfeed Posted: 16 Sep 2021 08:45 AM PDT Women with higher levels of PFAS in their system may be 20% more likely to stop breastfeeding early, according to a new study. |
| As a population gets older, automation accelerates Posted: 16 Sep 2021 08:45 AM PDT Economists authored a new study showing that aging populations lead to greater implementation of robots in workplace settings. |
| AI system identifies buildings damaged by wildfire Posted: 16 Sep 2021 08:45 AM PDT A deep learning approach to classifying buildings with wildfire damage may help responders focus their recovery efforts and offer more immediate information to displaced residents. |
| A statistical fix for archaeology's dating problem Posted: 15 Sep 2021 01:14 PM PDT Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there's never been a statistical fix that works -- until now. |
| Finding a metal-oxide needle in a periodic table haystack Posted: 14 Sep 2021 03:47 PM PDT Engineers develop a way to streamline complex material discovery. |
| A super material applicable to batteries and other energy conversion devices Posted: 14 Sep 2021 09:50 AM PDT Researchers have discovered a material that is only four atoms thick and allows for the study of the motion of charged particles in only two dimensions. Such studies could lead to pivotal discoveries in solid electrolytes for batteries and other applications. |
| Cylindrical phononic crystals sense physical, chemical properties of transported liquids Posted: 14 Sep 2021 08:13 AM PDT Phononic crystals are an innovative resonant platform for sensing and understanding the volumetric properties of liquids, attracting a growing interest from researchers. Researchers propose the design of a tubular phononic crystal for the purpose of sensing the biochemical and physical properties of a liquid filling the hollow part of the tube. |
| Algorithm finds personalized sound zones in cars for driver, passengers Posted: 14 Sep 2021 08:12 AM PDT Researchers outline an algorithm that adapts personalized sound zones within a car to changes in seat position, allowing riders to listen to their own audio without headphones and interruption. |
