An engineering team at Washington University in St. Louis says a compound found in green tea may be of particular benefit to patients struggling with multiple myeloma and amyloidosis. Aggregation of Full Length Immunoglobulin Light Chains from AL Amyloidosis Patients Is Remodeled by Epigallocatechin-3-gallate. Journal of Biological Chemistry, 2016; jbc.M116.750323 DOI: 10.1074/jbc.M116.750323

Epigallocatechine-3-gallate (EGCG), a polyphenol found in green tea leaves, may be of particular benefit to patients struggling with multiple myeloma and amyloidosis. These patients are susceptible to a frequently fatal condition called light chain amyloidosis, in which parts of the body’s own antibodies become misshapen and can accumulate in various organs, including the heart and kidneys...

The concept behind microbial fuel cells, which rely on bacteria to generate an electrical current, is more than a century old. But turning that concept into a usable tool has been a long process. Microbial fuel cells, or MFCs, are more promising today than ever, but before their adoption can become widespread, they need to be both cheaper and more efficient. Researchers at the University of Rochester have made significant progress toward those ends. In a fuel cell that relies on bacteria found in wastewater, Kara Bren, a professor of chemistry, and Peter Lamberg, a postdoctoral fellow, have developed an electrode using paper.

Until now, most el...

Terahertz wireless links to spaceborne satellites could make gigabit-per-second connection speeds available to anyone anytime, anywhere on the face of the earth, on the ground or in flight.

A Terahertz (THz) transmitter capable of transmitting digital data at a rate >100 gigabits (= 0.1 terabit) per second over a single channel using the 300-GHz band has been developed. This technology enables data rates 10X or more, faster than that offered by the fifth-generation mobile networks (5G), expected to appear around 2020. The THz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications.

The research group has developed a transmitter that achieves a communication speed of 10Gb/s using the frequency range from 290 – 315 GHz...

A team with the University of Hawaii, Ponta Grossa State University in Brazil and Stanford University has found what they believe is the reason that the surface of the sun rotates more slowly than its core. They used a new technique to measure the speed of the sun’s rotation at different depths and what it revealed about the speed of the sun’s outer 70km deep skin. Scientists have known that the surface of the sun spins more slowly than its interior but have no good explanation for it. In this new effort, the researchers were able to take a better look at what was occurring and by doing so discovered what they believe is the source of the slowdown.

To gain a better understanding of what is happen...
