Global warming link remains elusive
The first comprehensive study of glaciers on Antarctic Peninsula has uncovered widespread glacier retreat and suggests that recent climate change on the peninsula is responsible. Eighty-seven percent of the 244 marine glaciers have retreated over the last 50 years, a new study says. The widespread glacier retreat began at the northern, warmer tip of the Antarctic Peninsula. As atmospheric temperatures rose along the peninsula -- more than 2.5 degrees Celsius in the last 50 years -- the trend of retreat moved south toward colder mainland Antarctica. The paper appears in the 22 April, 2005 issue of the journal Science, published by AAAS the nonprofit science society
The research highlights the possibility that inland glaciers are accelerating their descent to the ocean and that the rate of sea level rise could be affected if ice shelves on the peninsula continue their retreat. "The widespread retreat of the glaciers on the Antarctic Peninsula over the last 50 years was largely caused by climate change. Are humans responsible? We cant say for sure, but we are one step closer to answering this important question," said Science author David Vaughan from the British Antarctic Survey in Cambridge, UK.

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...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
