The first case of Ebola in the United States was announced today, with a patient in Dallas who traveled to the US from Liberia. The resultant hysteria and xenophobia prompts this reminder. There is NO need to panic.
Ebola is NOT transmitted before a patient develops symptoms. Ebola is transmi... Read More
Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More
Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More
Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... Read More
Different view of an unknown airborne environmental isolate on Bile Esculin Agar (BEA) exhibiting a single circular colony. White hyphal growth with no spore formation. Clear to brownish exudate can be seen throughout the colony. This sample grew at refrigerated temperatures for several months.... Read More

About 6,000 years ago, a bacterium underwent a few genetic changes. These allowed it to expand its habitat from the guts of mice to that of fleas. Such changes happen all the time, but in this particular instance the transformation eventually resulted in the Black Death that wiped out a third of... Read More
BDP FL maleimide
BDP FL maleimide is a bright and photostable thiol-reactive dye for protein labeling, an ideal replacement for fluorescein for microscopy. BDP FL is a borondipyrromethene dye which has absorption and fluorescence spectra similar... Read More
Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.
Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... Read More
A team of scientists, led by researchers at The Wistar Institute, has identified a possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season. The findings, published in the Proceedings of the National Academy of Sci... Read More
Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More
It is universally accepted that the use of antibiotics will lead to antimicrobial resistance. Traditionally, the explanation to this phenomenon was random mutation and horizontal gene transfer and amplification by selective pressure. Subsequently, a second mechanism of antibiotic-induced antimic... Read More
One genome at a time can be exciting, but two even more so. I’m not entirely sure why this is, although it may explain our fascination with sex. And what if more than two entities were involved? What if the intimacy were not just between two individual organisms, but between a greater number of ... Read More

Nearly 40 years ago, a young Belgian scientist travelled to a remote part of the Congolese rainforest - his task was to help find out why so many people were dying from an unknown and terrifying disease.
In September 1976, a package containing a shiny, blue thermos flask arrived at the Instit... Read More
A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.
After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... Read More
A group of researchers at the Max F. Perutz Laboratories has created one of the three world's largest gene libraries for the Candida glabrata yeast, which is harmful to humans. Molecular analysis of the Candida glabrata fungus mutations led to the discovery of 28 new genes that are partly respon... Read More
How often have you heard of two or more bacterial species coexisting within the same cell of a host? It’s known to happen with some frequency in some amebas, insects and other invertebrates (including the strange case of the mealybug bacteria, which have an endosymbiotic bacterium that carries a...

One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
