Although it is expected that populations of many organisms will move away from the equator and toward the poles to stay cool during global warming, researchers have found that the intertidal zone does not exactly fit this pattern. A study published in this week’s Science Magazine indicates that there may be "hot spots" at northern shoreline sites within the next three to five years. This is partly due to the timing of the tides.
"Because they are assumed to live very close to their thermal tolerance limits, organisms inhabiting the rocky intertidal zone have emerged in recent years as potential harbingers of the effects of climate change on species distribution," explain the authors, three of whom are from the University of California, Santa Barbara.
Coauthor Carol Blanchette, a researcher with the Marine Science Institute at the University of California, Santa Barbara, says that neither air nor water temperatures alone are good proxies for body temperatures in intertidal organisms. Multiple climatic factors drive body temperature and the pattern of exposure to these conditions is influenced by shifts in the tidal cycle with latitude.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
