Mayo Clinic researchers say senolytic drugs can boost a key protein in the body that protects older people against aspects of aging and a range of diseases. Their findings, which are published in eBioMedicine demonstrate this in mice and human studies. Senolytics developed at Mayo Clinic and given once clear the bloodstream of senescent or "zombie" cells. These cells contribute to multiple diseases and negative aspects of aging. This study shows that the removal of senescent cells significantly boosts the production of a protective protein called a-klotho.

In AVS Quantum Science, scientists in Germany review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity. The team examined recent gravitational wave experiments, showing it is possible to shield large objects from strong influences from the thermal and seismic environment to allow them to evolve as one quantum object. This decoupling from the environment enables measurement sensitivities that would otherwise be impossible.

In the Journal of Renewable and Sustainable Energy, 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.

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. In Applied Physics Reviews, 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.

Natural microbial communities contain multiple species of bacteria, making it difficult to isolate and culture individual bacterial species. Two new tools allow researchers to genetically manipulate distinct bacterial species within their communities. Combined, these tools give researchers the ability to track genetic modifications as the community grows and to examine gene function in microorganisms that cannot be grown in the lab.
