| Treating cancer with light-sensitive nanoscale biomaterials Posted: 15 Mar 2022 08:29 AM PDT Treating cancer and other diseases with laser light is not currently considered routine, but new approaches using nanoparticles show some promise in improving existing techniques. Researchers review the status of the field and by combining photothermal therapy or photodynamic therapy with nanomaterials, they have been able to apply these types of phototherapies while also delivering drugs to sites in the body that are otherwise inaccessible. It is also possible to combine PTT and PDT into a single treatment, creating an even more powerful treatment method. |
| Optimizer tool designs, evaluates, maximizes solar-powered cooling systems Posted: 15 Mar 2022 08:29 AM PDT Researchers have developed an optimizer tool to design, evaluate, and maximize the performance of different types of solar-powered adsorption under various operating scenarios. The tool was created using Visual Basic programming language that is easy to learn and enables rapid application development and predicted the proper material mass concentration ratios. The method calculated the cooling load, predicted maximal performance, and conducted the overall performance analysis of the cooling system. |
| Models for molecules show unexpected physics Posted: 14 Mar 2022 12:44 PM PDT Engineers discover unusual properties in magnetized colloids that surprisingly adhere to the physics described by Kelvin's equation, which models the thermodynamics of molecular systems. |
| Meteorites that helped form Earth may have formed in the outer solar system Posted: 12 Mar 2022 07:30 AM PST Earth is believed to have formed partly from carbonaceous meteorites, which are thought to come from outer main-belt asteroids. Telescopic observations of outer main-belt asteroids suggest that they formed with ammonia ice which is only stable at very low temperatures. A new study suggests these materials may have formed very far out in the early Solar System then been transported into the inner Solar System by chaotic mixing processes. |
| Scientists make leap forward for genetic sequencing Posted: 11 Mar 2022 03:25 PM PST Researchers reveal new details about a key enzyme that makes DNA sequencing possible. The finding is a leap forward into the era of personalized medicine when doctors will be able to design treatments based on the genomes of individual patients. |
