Most people don’t think about microscopic remnants of their comfy jeans and other clothing that are shed during laundering. Now, researchers have detected indigo denim microfibers not only in wastewater effluent, but also in lakes and remote Arctic marine sediments.

Stanford engineers have genetically reprogrammed the cellular machinery of yeast to create microscopic factories that convert sugars and amino acids into plant-based drugs.

Memory cells remember previously encountered pathogens and help the body to react quickly and strongly when exposed to them again. However, the developmental process of strong immune cells that make these memory cells in advance without having to encounter the pathogens has now been discovered.

A team has developed novel imaging contrast agents using common dyes such as tattoo ink. When these dyes are attached to nanoparticles, they can illuminate cancers, allowing scientists to better differentiate between cancer cells and healthy cells.

Scientists studying life on the surface of glaciers in the Arctic and Alps have shown that, contrary to expectations, the viruses on glaciers in the Alps, Greenland and Spitsbergen are remarkably stable in the environment, challenging assumptions on virus evolution.

The combination of a biomolecule and a metal complex can target, bind, mark and damage cancer cells. A research team has manufactured such a theranostic agent that visualizes tumor cells by irradiation with visible light, and have demonstrated its effectiveness using lung cancer cells.

Asphalt is found in roads, on roofs and in driveways but its chemical emissions rarely figure into urban air quality management plans. A new study finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days.

By shining light pulses onto a needle, scientists have been able to transform it into an ultrafast “atomic hand”, enabling them to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second.

Researchers at the Smart-Aging Research Center (IDAC) at Tohoku University have developed an innovative training protocol that, utilizing immersive virtual reality (IVR), leads to real physical and cognitive benefits.

An experimental study suggests that sleep restriction may hinder information disclosure during criminal interviews, contradicting widespread assumptions about the effectiveness of sleep deprivation as an interrogation tool.
