Graphene plasmonics beats the drug cheats

Graphene plasmonics beats the drug cheats

Jan. 13, 2013 — Wonder material graphene could help detect the presence of drugs or toxins in the body or dramatically improve airport security, University of Manchester researchers have found Continue reading

Tiny machine apes production line

Tiny machine apes production line

11 January 2013 Last updated at 06:40 ET By Jonathan Amos Science correspondent, BBC News Manchester scientists have developed a tiny molecular machine that mirrors the function of the ribosome, which builds the proteins in our body’s cells. Just a few millionths of a millimetre in size, the minute machine resembles a ring threaded on a rod. As this ring moves along the rod, it picks chemical units and assembles them into chains, just as ribosomes join up the building blocks of proteins Continue reading

Modified antibodies trigger immune response, point to novel vaccine design strategies

Modified antibodies trigger immune response, point to novel vaccine design strategies

Jan. 7, 2013 — In an approach with the potential to aid therapeutic vaccine development, Whitehead Institute scientists have shown that enzymatically modified antibodies can be used to generate highly targeted, potent responses from cells of the immune system. The approach, referred to as “sortagging,” relies on the bacterial enzyme sortase A to modify antibodies to carry various payloads, such as peptides, lipids, fluorophores, and proteins Continue reading

Important factor in fat storage and energy metabolism

Important factor in fat storage and energy metabolism

Jan. 6, 2013 — As part of their ongoing research on the physiologic factors that contribute to the development of obesity, Joslin Diabetes Center scientists have identified a cell cycle transcriptional co-regulator — TRIP-Br2 — that plays a major role in energy metabolism and fat storage. This finding has the potential to lead to new treatments for obesity Continue reading
