Pipetting all those well-plates, baby, sends your thumbs into overdriveAnd spending long nights in the lab makes it hard for your love to thriveWhat you need is automation, girl, something easy as 1 2 3So put down that pipette, honey, I got something that will set you freeAnd it’s called epMotion (whisper: ‘cause you deserve something really great)Girl you need epMotion (whisper: yeah girl it’s time to automate)It’s got to be epMotion (whisper: no more pipetting late at night)Only for you epMotion (whisper: girl this time we got it right) DNARNAProteinsCell CulturesLess reagentsFaster workflowSaves you moneyWell, well, wellAnd it’s called epMotion (whisper: ‘cause you deserve something really great)Girl you need epMotion (whisper: yeah girl it’s time to automate)It’s got to be epMotion (whisper: no more pipetting late at night)Only for you epMotion (whisper: girl this time we got it right) Nebioq_UP...promovendo a Bioquimica e os Bioquimicos...

Nearly a century after the 1918 influenza pandemic claimed 50 million lives, survivors continue to produce powerful antibodies against the virus, researchers have found.These antibodies have now been isolated from their nonagenarian hosts and could be exploited to defend against future outbreaks. In work published this week in Nature

Short strands of RNA can help to dramatically suppress HIV infection in mice, according to scientists who have developed a method that uses antibodies to deliver the RNA directly into immune cells.Combinations of anti-retroviral drugs have made great strides in controlling HIV infections, but these drugs come with drawbacks. Unpleasant side effects, and the difficulties of sticking to complicated drug regimes, can all too often lead to treatment failure. Using RNA interference (RNAi) methods that target particular viral genes has seemed like a promising, less toxic alternative. But research has been hampered by the limitations of the small-animal models of HIV infection. Now proof-of-concept studies using newer mouse models have shown that it is possible to use short interfering RNAs (siRNAs) to combat HIV. Priti Kumar of Harvard Medical School, Boston, and her colleagues used mice lacking their own immune systems and into which researchers had introduced human haematopoietic stem cells – which give rise to all the different types of blood cell – to reconstitute an immune system closely resembling our own. The research, published this week in Cell



A British judge has ruled that a terrorism suspect cannot take secondary-school level courses in chemistry and human biology. In a first-of-a-kind ruling, High Court judge Stephen Silber said that the courses would put the suspect — who is referred to as A.E. for privacy reasons — in a “substantially stronger position” to carry out chemical and biological attacks. But scientists are unconvinced. An AS level in human biology is unlikely to provide much in the way of skills to a potential terrorist, says Charles Penn, a molecular microbiologist at the University of Birmingham. “I'm pretty sceptical that this is a real, tangible risk,” he says. The ruling paints a “misleading image of school chemistry being a subject of particular value to potential terrorists”, says Richard Pike, chief executive of the Royal Society of Chemistry. “There is nothing on the AS-level chemistry course that cannot be found easily on the web and through other means,” he says. A.E. is an ...

Um grupo de investigadores do Instituto de Biologia Molecular e Celular (IBMC) descobriu que uma estirpe de um fungo, a Neurospora crassa, é um potencial modelo biológico para estudar a morte celular programada. Entender o fenómeno da morte celular programada é considerado essencial para a compreensão de várias doenças como Alzheimer ou cancro e, por isso, todos os modelos que surgem são uma ferramenta importante. A descoberta, resultante de uma colaboração com a Universidade de Berkeley (EUA), foi hoje (11 de Julho) publicada na revista Journal of Biological Chemistry (factor de impacto 5,8). O grupo liderado por Arnaldo Videira, investigador do Instituto de Biologia Molecular e Celular (IBMC), descobriu que uma estirpe mutante de Neurospora crassa era mais resistente que a estirpe selvagem (não-mutante) a uma droga que induz a morte celular programada. Ao aprofundarem os estudos, os investigadores verificaram que a resistência resultava de uma menor produção de radicais livres. A falta de modelos biológicos era um grande entrave à investigação e por isso o artigo hoje publicado representa “uma nova possibilidade para a investigação ...
