The majority of tiny marine plants weathered the abrupt climate changes that occurred in Earth’s past and bounced back, according to a Penn State geoscientist.
"Populations of plankton are pretty resilient," says Dr. Timothy J. Bralower, head and professor of geoscience.
Bralower looked at cores of marine sediments related to thousands of years of deposition, to locate populations of these plankton during three periods of abrupt climate change. These abrupt changes were caused either by Oceanic Anoxic Events during the middle Jurassic to late Cretaceous when the oceans became uniformly depleted of oxygen or by a warming event in the early Paleocene around 55 million years ago.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
