Land snails are usually preserved as fossilized snail shells or imprints, while preservation of their soft bodies is a rarity. "Our new amber find is truly remarkable for this reason as well," explains Dr. Adrienne Jochum ...

1D model helps clarify implosion performance at NIF

In inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF), a spherical shell of deuterium-tritium fuel is imploded in an attempt to reach the conditions needed for fusion, self-heating and eventual ...

Ancient ammonoids' shell designs may have aided buoyancy control

Ammonoids, ancestors of today's octopus, squid and cuttlefish, bobbed and jetted their way through the oceans for around 340 million years beginning long before the age of the dinosaurs. If you look at the fossil shells of ...
