The Earth is 4.565 billion years old, give or take a few million years. How do scientists know that? Since there's no "established in" plaque stuck in a cliff somewhere, geologists deduced the age of the Earth thanks to a ...

Radiation hotspot detected in Tokyo: reports

A radiation hotspot has been detected in Tokyo, reports said Thursday as researchers carry out stringent tests to map how far contamination has spread from the crippled Fukushima nuclear plant.

Simulating the three-dimensional morphology of kilonovae

An advanced new three-dimensional (3D) computer simulation of the light emitted following a merger of two neutron stars has produced a similar sequence of spectroscopic features to an observed kilonova.

Fukushima's water release: what we know

Japan has announced plans to release wastewater from the stricken Fukushima-Daiichi nuclear plant into the ocean starting Thursday.

New results on geo-neutrinos from Borexino

(Phys.org) —Borexino is a liquid scintillator detector mainly built for solar neutrino searches. Due to its high level of radiopurity, a worldwide record, Borexino can also detect rare events such as electron-antineutrinos ...

Study shows bacteria can survive on radioactive elements

Bacteria that feed on methanol are able to grow on certain rare earth elements as well as their radioactive relatives. These findings suggest a possible role for such bacteria in the decontamination of areas where actinides ...

Filtering radioactive elements from water

The nuclear accident in Fukushima remains etched into many people's memories. It was a catastrophe that caused huge amounts of radioactively contaminated water to be released, which the operators of the nuclear power plant ...
