January temperatures linked to immigrant entrepreneurship

The slide into the new year can often be measured by the disappearance of string lights on roofs, a resurgence in gym memberships and perhaps most noticeable—colder winter weather. January holds the title as the chilliest ...

Growing algae outside of wastewater

Growing algae in wastewater has been a hot topic in research for years. News reports for decades have touted the latest research as bringing us within reach of new sources of fertilizer or environmentally friendlier biofuel.

California mice eat monarch butterflies

Monarch butterflies possess a potent chemical armor. As caterpillars, they eat plants filled with toxic cardenolides that build up in their bodies and make them unpalatable to most—but not all—predators. In central Mexico, ...

Toward a more inclusive definition of green infrastructure

Green infrastructure has been embraced as a tool to help cities achieve sustainability and resilience goals while improving the lives of urban residents. How green infrastructure is defined guides the types of projects that ...

Matter and antimatter seem to respond equally to gravity

As part of an experiment to measure—to an extremely precise degree—the charge-to-mass ratios of protons and antiprotons, the RIKEN-led BASE collaboration at CERN, Geneva, Switzerland, has found that, within the uncertainty ...

Controlling self-doping in magnetite with temperature

One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...

3D digital holograms on smartphones

3D holograms, previously seen only in science fiction movies, may soon make their way to consumer technology. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized ...

The first topological acoustic transistor

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...
