Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists from Cracow have proposed their own explanation of this phenomenon and presented predictions related to it, about consequences that are particularly interesting for high-energy neutrino astronomy.
A highly precise method to determine past typhoon occurrences from giant clam shells has been developed, with the hope of using this method to predict future cyclone activity.
A study published in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.
If humanity hopes to make it to Mars anytime soon, we need to understand not just technology, but the psychological dynamic of a small group of astronauts trapped in a confined space for months with no escape, according to a paper published in American Psychologist, the flagship journal of the American Psychological Association.
High above our heads, an unseen traffic jam is occurring as meandering jet streams cause eastward atmospheric circulations to become blocked, a process that can in turn create extreme events such as heat waves.
In the journal Temperature, researchers outline how quickly hot cars become deadly for children.
The oldest ice core so far provides 800,000 years of our planet's climate history. A field survey in Antarctica has pinpointed a location where an entire million years of undisturbed ice might be preserved intact.
Depending on the lighting, the surface of appropriately crafted nanoparticles can change its topography. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have shown that the molecular mechanism they have designed makes it possible, by the use of light, to effectively uncover or hide catalyst molecules. The technique they present leads to qualitatively new possibilities to control the course of chemical reactions.
Streams and rivers could pump carbon dioxide into the air at increasing rates if they continue to warm, potentially compounding the effects of global warming, a new worldwide analysis has shown.
