To collect a saliva sample, technicians instruct a person to tilt their head for two to five minutes and spit the accumulated saliva into a sterile tube. The saliva-filled tube is kept on ice and sent to the laboratory to test for the presence of biomarkers for cancer or other diseases.

Is Saliva the Next Frontier in Cancer Detection?

Scientists are finding tumor signals in spit that could be key to developing diagnostic tests for various types of cancer

The adaptive lighting cooked up by Camilla Rathsach and Mette Hvass would automatically adjust to the availability of moonlight, tweaking this church’s lighting automatically to balance visibility and darkness. This mock-up shows how the church would be lit under a full moon.

In anticipation of future demand, several projects are underway in the region to produce this clean energy source

Whales are tricky to see from a satellite. Belugas, with their light skin standing out against the water, are a bit easier to spot.

Can Satellites Really Detect Whales From Space?

Distant identification of whales is improving rapidly, but finding the behemoth creatures is still surprisingly tricky

Over several decades, researchers have identified more than 140 active compounds, called cannabinoids, in the cannabis plant.
