Bacteria Use ‘Invisibility Cloak’ To Hide From Human Immune…
Science Daily – Science Daily (press release) – Feb 24, 2008
A multidisciplinary research team from the Departments of Biology and Chemistry at York have been studying how bacteria capture the molecule used to make the ‘cloak’ called sialic acid. The researchers have now discovered an enzymatic activity that helps in the more efficient capture of sialic acids released from our cell surfaces. As well as using the sialic acid to make the ‘invisibility cloak’ other bacteria use similar methods to capture sialic acid as a simple food source so are literally eating us from the inside!Dr Gavin Thomas of the Department of Biology who led the research said: "This novel enzyme as well as other steps required for the formation of the ‘invisibility cloak’ that we have discovered in York now offers the chance to develop novel antimicrobials against these bacteria. "The work which was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) was undertaken by Dr. Emmanuele Severi (Biology – Thomas lab) in collaboration with Dr.

But Tinashe’s dream has been shattered. She returned to her missionary boarding school in Mashonaland East to complete her rdinary Levels to be welcomed by the sad news that she could no longer pursue science subjects her only door to the world of Hippocrates. GA_googleFillSlot( “AllAfrica_Story_Inset” );The reason: biology chemistry and physics teachers had left the school like many other members of their previously hallowed fraternity in search of greener pastures. Now Tinashe is studying Integrated Science. It looks like the country has been robbed of another aspiring doctor. Tinashe said: "I did science subjects the whole of last year but when we came back to school this term we were told that our chemistry physics and biology teachers had left. So we had to drop the subjects.

n the other end of the spectrum are the illnesses we get when we don’t eat certain foods. And here I’m thinking of scurvy which is covered nicely by our final food scholar Pierre Laszlo in Citrus: A History. Laszlo is a chemistry professor who is probably best known for his previous book Salt: Grain of Life and has now moved on to one of the next great essential staples citrus. Laszlo has a truly charming way of telling the story weaving his personal biography into the tale of the migration of various fruits around the world. He is careful though (and tells us he is worried about overstepping his bounds) to never let the personal overshadow the story of lemons limes grapefruits oranges and of course such exotics as ugli fruit kumquats and yuzu. Citrus is a little different than the other books. While there’s still plenty of great history in Laszlo’s account it’s a little more interdisciplinary adding to his personal tale and all that lore discussions on chemistry and three great chapters on the symbolic meanings of citrus and the image of these fruits in poetry and art.

Deng came off the bench for the third straight game since returning from injury and scored 10 points in 24 minutes. Gordon scored five points in 26 minutes and needed a late three-pointer to do that shooting 2-for-11 overall. “We got new guys so there wasn’t much chemistry because they were trying to get acclimated” Gordon said. The rotation will be an adjustment. It’s going to affect everybody on the team. We have to find a way to have chemistry… The rotation will be an adjustment. It’s going to affect everybody on the team. We have to find a way to have chemistry. As for the other new Bulls Cedric Simmons played the final 2:11 of mop-up time and made his only field-goal attempt for two points and Shannon Brown was inactive. Thomas in his second straight strong performance topped the Bulls with 18 points. “You’d always like to get a win” Hughes said. “But we’ll be fine.
