Global climate change means that recently discovered ancient forests in Canada's extreme north could one day return, according to Alexandre Guertin-Pasquier of the University of Montreal's Department of Geography, who is presenting his findings at the Canadian Paleontology Conference in Toronto today.

"According to the data model, climate conditions on Bylot Island will be able to support the kinds of trees we find in the fossilized forest that currently exist there, such as willow, pine and spruce. I've also found evidence of a possible growth of oak and hickory near the study site during this period.," Guertin-Pasquier said. "Although it would of course take time for a whole forest to regrow, the findings show that our grandchildren should be able to plant a tree and watch it grow."The fossilized forest found on Bylot Island in Nunavut is between 2.6 and 3 million years old according to estimations based on the presence of extinct species and on paleomagnetic analyses. Paleomagentic analysis involves looking at how the Earth's magnetic field has affected the magnetic sediment in rocks – like a compass, they turn to follow the magnetic poles. Scientists can use this information to date rocks as the history of the movement of the magnetic poles is relatively well known.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
