What is Barmuda Triangle?
What is Barmuda Triangl?
The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean in which a number of aircraft and surface vessels are alleged to have disappeared in mysterious circumstances which fall beyond the boundaries of human error, piracy, equipment failure, or natural disasters. Popular culture has attributed some of these disappearances to the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings.

Unique Volcanic Complex Discovered On Moon's Far Side
ScienceDaily (April 09, 2014) — Analysis of new images of a curious "hot spot" on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon's thermal history.
The hot spot is a concentration of a radioactive element thorium sitting between the very large and ancient impact craters Compton and Belkovich that was first detected by Lunar Prospector's gamma-ray spectrometer in 1998. The Compton-Belkovich Thorium Anomaly, as it is called, appears
Nanoplasmonic 'Whispering Gallery' Breaks Emission Time Record in Semiconductors
ScienceDaily (April 08, 2014) — Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to drastically reduce emission lifetime, a key property of semiconductors, which can lead to the development of new ultrafast photonic devices.
The research was conducted by associate professor Ritesh Agarwal, postdoctoral fellows Chang-Hee Cho and Sung-Wook Nam and graduate student Carlos O. Aspetti, all of the Department of Materials Science and Engineering in Penn's School of Engineering and Applied Science. Michael E
Their research was published in the journal Nature Materials.
