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.

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.

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.

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.

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.

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.

Researchers have published maps indicating how the auroral zone has moved over the last three millennia.
