#3d bone marrow made from silk biomaterials successfully generates platelets (Nanowerk News) Researchers funded by the National Institute of Biomedical Imaging
The team knew from their previous work with silk protein scaffolds that silk is a very biocompatible material that is amenable to many manipulations to customize it for a specific use,
They formed silk scaffolds of different thicknesses (ranging from 2 to 5 micrometers) and stiffness combined with growth factors,
the researchers attached the silk scaffolds to a plastic framework to guide the growth of cells.
Next, endothelial primary cells (EPCS) were grown on one side of the silk scaffold and megakaryocytes were seeded on the other side.
the researchers formed silk sponges around porous silk microtubes. The wall thickness of the microtubes was kept below 10 micrometers,
in addition to the EPCS, allowed the resulting silk structure to support the formation of functioning platelets.
Each step of the tissue engineered silk bone marrow development furthered the amount of successful platelet production

alerting the wearer by turning on an LED light("Ultrasensitive and Highly Selective Graphene-Based Single Yarn for Use in Wearable Gas Sensor").
"The researchers, from the Electronics and Telecommunications Research Institute and Konkuk University in the Republic of korea, coated cotton and polyester yarn with a nanoglue called bovine serum albumin (BSA.
The yarns were wrapped then in graphene oxide sheets. Graphene is an incredibly strong one-atom-thick layer of carbon,
and is known for its excellent conductive properties of heat and electricity. The graphene sheets stuck very well to the nanoglueo much
so that further testing showed the fabrics retained their electrical conducting properties after 1, 000 consecutive cycles of bending
Finally, the graphene oxide yarns were exposed to a chemical reduction process, which involves the gaining of electrons.
Exposure of these specially-treated fabrics to nitrogen dioxide led to a change in the electrical resistance of the reduced graphene oxide.
The fabrics were so sensitive that 30 minutes of exposure to 0. 25 parts per million of nitrogen dioxide (just under five times above the acceptable standard set by the U s. Environmental protection agency) elicited a response.
The fabrics were three times as sensitive to nitrogen dioxide in air compared to another reduced graphene oxide sensor previously prepared on a flat material.

#China Will Launch Cap -And-Trade Program To Limit Carbon emissions President Xi Jinping of China announced today during a visit to the White house that China will start a national cap

and then sells permits to companies that want to emit pollutants. Companies can trade their permits,
China cap-and-trade program will help the country reduce emissions from some of its most polluting sectors,
Regional cap-and-trade programs already exist in China. Between 2013 and 2014, the Chinese government launched seven pilot cap-and-trade programs in the cities of Beijing, Shanghai, Tianjin, Shenzen,
and Chongqing, as well as in the provinces of Guangdong and Hubei. But China agreement to a national cap-and-trade program,
which Obama officials said have been in the works since April, represents the country first wide-ranging plan for limiting its emissions.
China has yet to announce specifics about its cap-and-trade plan, leaving some concerned about the political and technical challenges that lie ahead."
what the actual cap is.""If China sets limits that will peak its emissions before 2030,

while others argue that the strategy rewards big polluters that can afford to buy permits. In his first term, President Obama tried to pass a similar cap-and-trade program,
but the measure was rejected by the Senate, in part among concerns from American politicians that setting emissions limits would harm the U s. ability to compete economically with China.
