An international team of researchers, led by scientists from GSI/FAIR in Darmstadt, Germany, has studied r-process ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

A significant negative δ 238 U excursion (~0.4‰) starting just prior to the onset of the negative carbon isotope excursion within the Toarcian Oceanic Anoxic Event (T-OAE) has been recorded, followed ...

Here, we report the isotope effect of hydrogen terminations in the layered Ge on lattice vibrations and electronic and atomic structures. We show that the Ge–Ge in-plane vibration responds to the mass ...

To save elephant populations from extinction, the international community banned the sale of their ivory — but selling mammoth ivory remains legal ...

Good afternoon and happy Monday, readers! Tens of millions of Americans are under extreme heat alerts today and into much of the week. If you live in one of the states suffering from the high ...

The Doomsday Clock now stands at 89 seconds to midnight, signalling an unprecedented threat of global catastrophe.

The International Atomic Energy Agency (IAEA) has convened an emergency meeting on Monday in the light of the urgent situation in Iran and has confirmed that ‘’no increase’’ in off-site radiation ...

The IAEA has consistently underlined, as stated in its General Conference resolution, that armed attacks on nuclear facilities should never take place, and could result in radioactive releases with ...

On 18 June, the IAEA said in an update that it had information that two centrifuge production facilities in Iran – the TESA Karaj workshop and the Tehran Research Center – were hit. Both locations ...

We investigated the mechanisms and isotope effects associated with the N-dealkylation and N-atom oxidation of substituted N-methyl- and N,N-dimethylanilines to identify isotope fractionation trends ...
