Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being compressed. The plant’s hardiness comes from a combination of its hollow, tubular macrostructure and porous, or cellular, microstructure. These architectural features work together to give grass its robust mechanical properties. Harvard SEAS, Wyss Institute and MIT have developed a new method to 3D print materials with independently tunable macro-and microscale porosity using a ceramic foam ink...

Engineering Team finds Green Tea Compound may Halt Molecular Cause of Often-Fatal Condition

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.

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...

Missing Link for Fighting Viral Pneumonia identified

Loss of IL-27 signaling results in increased disease severity and lung immunopathology after SeV.

Loss of IL-27 signaling results in increased disease severity and lung immunopathology after SeV.

Respiratory syncytial virus (RSV) causes ~60,000 hospitalizations of children aged 0 to four, and nearly 200,000 hospitalizations and 14,000 deaths among adults 65 and older. However, there are virtually no vaccines or treatments for these infections. Perelman School of Medicine at the University of Pennsylvania and the University of Pennsylvania School of Veterinary Medicine found evidence that cytokine Interleukin 27 (IL-27), may be the key to fighting and treating these infections.

Working with a mouse-model of parainfluenza virus infection, Sendai virus, which causes similar symptoms and patterns of tissue damage to RSV, researchers found that mice fared much worse in fighting the infectio...
