Science has a way of forcing us to reexamine some of our basic assumptions about nature. Consider the following statement: Animals that thrive in high temperatures are more likely to survive global warming than those that are less tolerant to heat. While this conclusion may seem obvious, a new study in the journal Science finds that the opposite may be true.
In an experiment published in the July 4 edition of Science, Stanford University postdoctoral fellow Jonathon H. Stillman examined the effect of climate change on porcelain crabs (genus Petrolisthes) – inch-long invertebrates that inhabit coastal areas throughout the Pacific Ocean. Stillman discovered that porcelain crabs in the cool Pacific Northwest have the ability to adjust to larger increases in habitat temperature than crabs living in the warm coastal waters of Mexico.
The study showed that cold-water crabs have a greater capacity to adjust their heat-tolerance thresholds than warm-water crabs," said Stillman, who conducted the experiment at Stanford’s Hopkins Marine Station in Pacific Grove, Calif. This is definitely counterintuitive. You would expect heat-tolerant organisms to be the most resilient to global warming, but it turns out they may have a harder time surviving as their habitat temperatures increase," he added, noting that a half-degree increase in the Earth’s temperature could be enough to wipe out countless porcelain crabs:

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
