Upon learning that all life on Earth is essentially based upon the element carbon, one may be compelled to ask that question "Why couldn't organic life evolve from a different element?" This research project seeks to discover reasons why life favors a carbon base and to determine the ...

A review is given on the recent progress of silicon-based on-chip hybrid multiplexers, which are the key elements to enable more than one (de)multiplexing techniques simultaneously, including wavelength-division-multiplexing (WDM), polarization-division-multiplexing (PDM), and mode-division-multiplexing...
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were...
After a sustained assault from lawmakers, investigators and victims groups, the website Backpage.com agreed early this year to shut down its lucrative adult page, which had become a well-known sex-trafficking hub.
Other silicon-based life forms are said to exist there but few appeared in the books. In the Star Wars universe, at least two life forms are based on silicon, and they live in space: the Mynocks and the Space slugs. A silicon-based life form, the Horta, appears also in the Star ...
Section3begins with an overview of the different characterization techniques that have been applied to the silica bilayer system, both experimentally and theoretically. As silica materials are ubiquitous in everyday life, the ability to obtain structural and chemical information on a silica system in ...
Earth can be reproduced if their growth occurred by a combination of collisions and pebble accretion during the disk lifetime. Irrespective of the model parameters, our results require that Mars and the proto-Earth completed their growth within the 5-Myr disk lifetime (Extended Data Fig.2). ...
Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations. 4.5 DOT Emergency Guidelines /GUIDE 116: GASES - FLAMMABLE (...
