11:00 AM | The Curious Case of a Protein and a Pilus
by Monika Buczek | If you’re like me, every morning you reluctantly roll out of bed and automatically reach for your toothbrush. One of the earliest learned practices of personal hygiene, brushing surely serves more than just preventing daybreak halitosis- but have you ever pondered about the plaque you try to dislodge from your…

10:58 AM | Ebola, nuovi casi in Congo
Dopo Sierra Leone, Guinea, Liberia e Nigeria, l’epidemia di ebola, la più grande che la storia ricordi, è arrivata anche nella Repubblica Democratica del Congo, lì dove il virus causò la sua prima epidemia nel 1976. Dopo l’annuncio di 13 decessi per febbre emorragica sospetta, è arrivata infatti la conferma della presenza di ebola nel paese, con la positività riscontrata nei test effettuati su due persone. Il ministro della salute Felix […]

9:07 AM | Classic Italian botany
Here’s some historical Italian botany; an illustration by Jacopo Ligozzi on display in the Palazzo Pitti and photographed without flash in keeping with museum policy.  Always impressed by how well this camera does in low light conditions. The interesting thing is that this lovely illustration (ca. 1577-1567) of mandrake (Mandragora autumnalis – Nightshade family) is pretty accurate (flowers aren't quite right) while illustrations of an earlier era portrayed this famous toxic […]

7:52 AM | Promiscuity accelerates ageing
Reproduction comes at a cost: animals that reproduce a lot age faster than animals that don’t. There is also a cost associated with sexual interaction itself, not just the resulting reproduction. Promiscuous female fruit flies age faster than their monogamous or celibate friends. This is partly because some of the proteins in male fly semen […]

7:02 AM | La preistoria del sistema solare
Nonostante il Sole sia la stella a noi più vicina, gli scienziati stanno ancora cercando di scoprire con esattezza quali sono i passaggi che hanno portato alla sua origine e alla conseguente formazione del sistema solare. Uno studio, pubblicato di recente suScience, rappresenta oggi un importante passo in avanti, in quanto mostra come il densissimo materiale che ha generato il sistema solare si sarebbe isolato dal resto della materia della galassia circa 30 milioni di anni prima della […]

7:00 AM | Yellowstone National Park Is Not Bringing The Apocalypse
Many mainstream publications recently posited that Yellowstone National Park, which is effectively situated on top of a supervolcano, might soon erupt in a manner which would destroy America and civilization as we know it. The story was widely covered (because fear is easy to sell), but the real story hasn't received the same coverage. Analysis of the seismic activity around the area indicates that there will not be any supervolcanic eruptions for hundreds of millennia. The post Yellowstone […]

6:38 AM | Vanilla for One
More than any other plants orchids are evocative of the exotic. In fact as a family the orchids are highly cosmopolitan, occurring almost everywhere on earth. With more than 20,000 species it is the largest family of flowering plants. In temperate regions most orchids are ground dwelling perennial herbs, however the majority of orchids live […]

6:06 AM | Tortoise Sorting
Indian star tortoise Geochelone elegans, copyright P. G. Palmer.As a whole group, the 'true' tortoises of the family Testudinidae are easily recognised, with a usually terrestrial habitus (though at least one species, the serrated hinge-back tortoise Kinixys erosa, is a capable swimmer), columnar legs with short heavy-clawed feet, and a relatively high carapace. But relationships within the tortoises have seen a bit of shuffling around in recent years, and nowhere has that shuffling been more […]

Un grupo de investigadores estadounidenses ha encontrado a 800 metros de profundidad, bajo el hielo antártico, un verdadero vergel de vida microbiana que sobrevive en un ecosistema de total ausencia de luz y a temperaturas por debajo de los cero grados centígrados. El hallazgo tendrá implicaciones para la búsqueda de vida en ambientes extremos, tanto dentro como fuera de la Tierra. Bajo el espeso hielo de la Antártida bulle la vida microbiana. Así se […]

6:09 PM | Apps for Academia: Let's Talk Tech
A big part of training to be a scientist is training to be productive. Grad students and faculty do a lot of different things in a set amount of time, and that amount of time always stubbornly stays the same or reduces. Improving efficiency not only allows you to have more time for non-work things, but also allows you to devote valuable time to tasks that need creativity instead of efficiency. My advisor often tells us that we are too busy and need more time to sit around and think. As […]

1:31 PM | This Month in Blastocystis Research (AUG 2014)
Some August highlights in Blastocystis research:1) The PRE-IOPCA Molecular Parasitology Workshop took place from the 7-10 August at CINVESTAV, Mexico City. Top-motivated students from some 10-15 countries worked hard from 7 am to 7 pm in dry+wet lab sessions, and we all had a really great time, thanks to both participants and fantastic organisers. There was a 4 h session on Blastocystis molecular epidemiology, and I was pleased to learn that some of the participants currently work with (or plan […]

7:48 AM | The Monster Leech That Will Crawl Right Up Your Nose
Deep in the Amazon rainforest lives a creature that only grows as long as your pinkie . . . yet it’s one of the most monstrous creatures on the planet. Known as the Tyrannobdella rex, this sharp-toothed beast is a leech with disturbingly large fangs (well, for a leech, anyway). And unfortunately, this Peruvian parasite has a really bad habit of climbing up people’s noses. The post The Monster Leech That Will Crawl Right Up Your Nose appeared first on […]
