We owe it all to comets

Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. Now Tel Aviv University justifies our fascination --...

Geochemist duo offer new explanation for dearth of xenon in Earth's atmosphere

(Phys.org)—The Earth's atmosphere holds far less xenon than chondritic meteorites, and researchers have sought for years to explain why. Now, geochemists Svyatoslav Shcheka and Hans Keppler of...

Noble gases hitch a ride on hydrous minerals

The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they...

A noble gas cage: New material traps gases from nuclear fuel better

When nuclear fuel gets recycled, the process releases radioactive krypton and xenon gases. Naturally occurring uranium in rock contaminates basements with the related gas radon. A new porous material...
