| Scientists develop new sensor to capture calcium activity in cells Posted: 19 Oct 2021 09:01 AM PDT Researchers have developed a novel approach for detecting the activity of calcium within cells. The study demonstrates the effectiveness of a red biosensor that can directly monitor calcium at specific locations within a cell, a discovery that could aid in better understanding of the molecular basis of human diseases. |
| New study calls for mitigation, monitoring of common grease-proofing food packaging chemicals Posted: 19 Oct 2021 09:01 AM PDT A scientist is calling for a better understanding of the health ramifications of ubiquitous 'grease proofing' chemicals that have been used for decades. A new study based on a symposium involving scientists at public and private institutions strikes an urgent tone on the need for new and better ways to detect and mitigate this class of chemical compounds, collectively known as per- and polyfluoroalkyl substances. |
| Motorized droplets thanks to feedback effects Posted: 19 Oct 2021 08:05 AM PDT Physicists have examined a special system of colloidal particles that they activated using laser light. The researchers discovered that self-propelling droplets, which they have named 'droploids', formed which contain the particles as an internal motor. |
| New technique paves the way for perfect perovskites Posted: 19 Oct 2021 08:05 AM PDT Scientists have developed a new technique that allows researchers to synthesize a perovskite solar material, characterize its crystal structure, and test its response to light at the same time. |
| New model points to solution to global blood shortage Posted: 19 Oct 2021 08:05 AM PDT A mathematical model of the body's interacting physiological and biochemical processes shows that it may be more effective to replace red blood cell transfusion with transfusion of other fluids that are far less in demand. |
| New fibers can make breath-regulating garments Posted: 19 Oct 2021 05:27 AM PDT A new kind of fiber can be made into clothing that senses how much it is being stretched or compressed, and then provides immediate tactile feedback in the form of pressure, lateral stretch, or vibration. Such fabrics could be used in garments that help train singers or athletes to better control their breathing, or that help patients recovering from disease or surgery to recover their breathing patterns. |
| Twelfth century literature and space-age data help map 3,000 years of auroras Posted: 14 Oct 2021 11:20 AM PDT Researchers have published maps indicating how the auroral zone has moved over the last three millennia. |
