Researchers have developed a way of detecting circulating tumor cells in the bloodstream of pancreatic cancer and lung cancer patients.

Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions.

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Chemistry researchers have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.

Bioengineers have developed a new construction kit for building custom sense-and-respond circuits in human cells. The research could revolutionize therapies for complex conditions like autoimmune disease and cancer.

Hula hooping is so commonplace that we may overlook some interesting questions it raises: 'What keeps a hula hoop up against gravity?' and 'Are some body types better for hula hooping than others?' A team of mathematicians explored and answered these questions with findings that also point to new ways to better harness energy and improve robotic positioners.

Steroid hormones are among the most widespread aquatic micropollutants. They are harmful to human health, and they cause ecological imbalances in aquatic environments. Researchers investigated how steroid hormones are degraded in an electrochemical membrane reactor with carbon nanotube membranes. They found that adsorption of steroid hormones on the carbon nanotubes did not limit the hormones' subsequent degradation.

A research team has shown wearable electronic textiles (e-textiles) can be both sustainable and biodegradable.

Chlorine plays an essential part in daily life, from keeping pools clean to preserving food. Now, a team of chemists developed a more environmentally friendly way to integrate chlorine into chemical building blocks for medications, plastics, pesticides and other essential products while reducing costs.

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components.

A research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials.

Scientists have developed a nanopore-based tool that could help diagnose illnesses much faster and with greater precision than current tests allow, by capturing signals from individual molecules.

Groundbreaking cerium oxide-based thermal switches achieve remarkable performance, transforming heat flow control with sustainable and efficient technology.

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed.
