Microscopic sensors that are as thin as a strand of hair but capable of taking multiple measurements simultaneously could revolutionize the diagnosis and monitoring of diseases like cancer. Researchers from Adelaide University’s Institute for Photonics and Advanced Sensing and the University of Stuttgart in Germany worked together to develop the tiny sensors using state-of-the-art, ultrafast 3D microprinting technology.

The unique sensors target specific biomarkers and are printed directly onto the tip of optical fibers...

A blood test, combined with an ultrathin material derived from graphite, could significantly advance efforts to detect Alzheimer’s disease at its very earliest stage, even before symptoms appear.

Alzheimer’s disease is the most common form of dementia. For millions of Europeans—and the health services that care for them—it is a ticking time bomb, with still no cure. But EU researchers are developing a simple tool to enable much earlier detection, potentially decades before symptoms appear.

Early detection matters because treatment is most effective when started as soon as possible. This gives people a better chance to slow the progression of the disease and plan for the future...

Hidden ice beneath Mars’ surface may mark the spot where humanity first sets foot on the Red Planet. A newly identified region on Mars may hold the key to future human landings. Researchers found evidence of water ice less than a meter beneath the surface, close enough to be harvested for water, oxygen, and fuel. The location strikes a rare balance between sunlight and cold, helping preserve the ice. It could also offer clues about whether Mars once supported life.

Before humans can make the long trip to another world, scientists must identify a safe and practical place to land. New research led by a University of Mississippi scientist suggests one region on Mars may meet many of the requirements for future human missions.

In the U.S., one in five of the 37 million adults who has diabetes doesn’t know it. Current methods of diagnosing diabetes and prediabetes usually require a visit to a doctor’s office or lab work, both of which can be expensive and time-consuming. Now, diagnosing diabetes and prediabetes may be as simple as breathing.

A research team led by Huanyu “Larry” Cheng, James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, has developed a sensor that can help diagnose diabetes and prediabetes on-site in a few minutes using just a breath sample...
