It has finally been installed at SINTEF after eight years of planning and construction. This mammoth of a device, nicknamed the “Polyax Rocker” is now set to re-create with ultra-high precision the geological stresses acting on oil reservoirs.

Shedding light on zooplankton in the dark

We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.

A “health centre” for juvenile salmon

The condition of the water in salmon hatcheries can tell us a great deal about when and why outbreaks of disease occur. Now, SINTEF researchers are about to expose the water’s secrets, both to prevent suffering in fish and to save the aquaculture industry a great deal of money.

Infidelity can be forgiven – but at a cost

Most people who have been unfaithful do not believe it when their partner says they forgive them. And the fact that men often don’t realize that emotional infidelity is a problem just feeds the conflict.
