Researchers have created tiny, vehiclelike structures that can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room ...
As climate change advances, the ocean's overturning circulation is predicted to weaken substantially. With such a slowdown, scientists estimate the ocean will pull down less carbon dioxide from the atmosphere.
We often hear that Aboriginal peoples have been in Australia for 65,000 years, "the oldest living cultures in the world." But what does this mean, given all living peoples on Earth have an ancestry that goes back into the ...
As predicted by the theory of general relativity, the passage of gravitational waves can leave a measurable change in the relative positions of objects. This physical phenomenon, known as gravitational wave memory, could ...
Imagine being able to watch the inner workings of a chemical reaction or a material as it changes and reacts to its environment—that's the sort of thing researchers can do with a high-speed "electron camera" called the ...
Our clothes are made mainly of plastic.
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up ...
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide ...
A research team from Japan, including scientists from Hitachi, Ltd. (TSE 6501, Hitachi), Kyushu University, RIKEN, and HREM Research Inc. (HREM), has achieved a major breakthrough in the observation of magnetic fields at ...
When radionuclides enter our organism, whether by inhalation, ingestion, or through wounds, they pose a potential health risk. Many previous studies on radionuclide exposure have focused mainly on animal experiments. However, ...
