Ryan Ickert, senior research scientist with Purdue EAPS, is a co-author of the paper. He uses heavy radioactive and stable isotopes to study the timescales of geological processes. He demonstrated that other isotope data (previously used to estimate the timing of water-rock interaction on Mars)...
EARTH excepted, the most probed and prodded planet in the solar system is Mars. Besidesthe assortment of craft that have flown by it or gone into orbit around it, three roboticbuggies equipped with cameras and scientific instruments have roamed the Martian surfaceon behalf of NASA, America's s...
The research team used data from the Chinese Chang'E lunar orbiters to find extra heat below the surface of a region thought to once host an ancient volcano. The source may have been granite's high levels of radioactive elements, such as uranium and thorium, according to the new paper. ...
Decaying radioactive materials inside laptops, phones and other electronic devices, such as packaging material for integrated circuits that emits alpha particles, can also cause an SEU, Bhuva says. Frequently Answered Questions What computer error is caused by cosmic rays? Cosmic rays can cause single...
Additionally, 89Zr doesn't require highly enriched targets, has lower production energy, and doesn't cause radioactive uptake in non-targeted organs compared with 124I [40]. Table 1 PET/CT radiotracers in oncology: Full size table Applications for fibrosis imaging While the utility of PET is ...
We find that heat flowing out of the silicate mantle can melt an ice layer from below (in some cases episodically), depending mainly on the thickness of the ocean-ice shell, the mass of the planet, the surface temperature and the interior parameters (e.g. radioactive mantle heat sources)...
Marsinum is a new crystal being found on Mars for the first time. It is made up of radioactive isotopes forming a crystal structure, never seen before. Its structure allows it to concentrate huge amounts of energy in its crystal lattice, making it not only radioactive but highly unstable ...

Human hunger is stimulated by the hormone ghrelin, which is produced mainly by the stomach, but also in the brain, small intestine and pancreas, according to theCleveland Clinic. This hormone is released when the stomach is empty so it can alert the brain that it's time to eat. ...
