1:50 PM | Looking back on 2013: Plantwise brainstorm
Last year, 2013, was a productive year for Plantwise. There were over 120,000 visits to the online knowledge bank, with over 250,000 page views. This is great news because there were over 15,000 views per month, with people exploring distribution maps, browsing the image-led diagnostic tool, and looking at factsheets on treatment of pests and […]

1:47 PM | Seconda edizione della Scuola di Neuroetica della SISSA

1:45 PM | Some Bees Are Busier Than Others
It may be time to leave “busy as a bee” with other dubious animal similes like “happy as a clam” and “drunk as a skunk.” That’s because some bees, it turns out, aren’t all that busy. A small group of hive members do the bulk of the foraging, while their sisters relax at home. But […]The post Some Bees Are Busier Than Others appeared first on Inkfish.

1:15 PM | WIPP fire, great heat produced
There was a recent report produced by the experts at Los Alamos  about the fire at the WIPP facilities: Based solely on the photographic information it appears that some surfaces on the LANL drum may have reached temperatures of up to 700-870°C10 and the waste in a large portion of the room reached temperatures up to […]

12:50 PM | Friday SNPpets
Welcome to our Friday feature link collection: SNPpets. During the week we come across a lot of links and reads that we think are interesting, but don’t make it to a blog post. Here they are for your enjoyment… RT @kbradnam: Yesterday I blogged about another example of multiple bioinformatics tools that share the same […]

12:47 PM | Scrawny Wonderpus Puts Stranglehold on Mightier Mimic Octopus
Earlier this week, we learned that female octopuses sometimes strangle—and then possibly eat—their male mates. For a cannibalistic animal with long arms, perhaps we—and the male—should have seen that... -- Read more on ScientificAmerican.com

12:09 PM | Gaza, i bombardamenti visti dallo Spazio
“La mia foto più triste. Dalla Stazione spaziale internazionale riusciamo a vedere le esplosioni e i razzi che volano sopra Gaza e Israele”. È l’amaro commento di Alexander Gerst, astronauta tedesco dell’Agenzia spaziale europea, che correda la foto – altrettanto amara – da lui scattata e pubblicata mercoledì scorso. Il nostro Luca Parmitano ci aveva abituato a fotografie ben più amene: questa volta si tratta di un’immagine […]

12:00 PM | Where’s the site for the parasite?
I’ve had the good fortune to have a glut of papers appear, thanks in part to the publication of symposium proceedings I helped organized with Kelly Weisnersmith. One of the papers in the symposium proceedings is the follow-up to Carreon and colleagues (2011), which I described here. (My goodness, was that three years ago already?)In our previous paper, we showed that living inside the neural tissue of shrimp were these little baby tapeworms:After Nadia Carreon (pictured) finished her […]

11:49 AM | New Special Issue on Morphology and Evolution of Lizards
Juan Daza asks: Can you identify this lizard? He continues: If you have no idea, it’s not because it’s not an Anolis; in fact, this is an imaginary lizard that was reconstructed based on the remains of a 110 my old fossil from the Gobi Desert and a mosaic of features from different living geckos such […]

10:11 AM | Simulare il viaggio nel tempo con un fotone
Cosa succederebbe se tornaste indietro nel tempo, e uccideste vostro nonno prima che incontrasse la nonna? Si tratta del cosiddetto paradosso del nonno, uno scenario ipotetico proposto per la prima volta dallo scrittore francese René Barjavel, che è stato spesso utilizzato per sottolineare l’impossibilità dei viaggi nel tempo (ma anche come spunto per girare classici della fantascienza come Ritorno al Futuro). La teoria delle relatività e la fisica quantistica […]

10:11 AM | Americans and Math
From the current issue of The New York Times Magazine: One of the most vivid arithmetic failings displayed by Americans occurred in the early 1980s, when the A&W restaurant chain released a new hamburger to rival the McDonald’s Quarter Pounder. With a third-pound of beef, the A&W burger had more meat than the Quarter Pounder;…

9:36 AM | Image of the Week: Aspergillus fumigatus
The image above is an artistic impression of a microscopic view of the fungus Aspergillus fumigatus, a common organism in the environment typically found in compost heaps and decaying vegetation. The green flower-like structure is the conidial head that produces thousands of spores (conidia), which can be released into the atmosphere. It is estimated that […]

9:27 AM | L'età del primo ciclo è controllata da oltre 100 geni
Fra i 10 e i 15 anni: è questo l’intervallo di età in cui compare il primo ciclo mestruale (almeno nella maggior parte delle ragazze europee). E il meccanismo che regola questa “sveglia” è molto più complicato di quanto non si immaginasse finora. Sono più di 100, infatti, i geni coinvolti nel controllo di questo fenomeno, e alcuni sono sottoposti a “imprinting genomico”, cioè hanno un effetto diverso a seconda che siano […]

9:00 AM | On the mythology of natural selection. Part IX: What would it mean if selection really were deterministic?
Today's post will have to do with the question, "What is cause?". This will be a bit abstract, but I hope it will be at least somewhat understandable.We have been writing about the subject of genetic determinism and its twin, deterministic natural selection.  Pure determinism means that when I know an organism's genotype I can perfectly predict its traits and that given different organisms' genotypes I can perfectly predict their relative fitness (reproductive success).  It's one […]

7:08 AM | Cosa guida i movimenti degli storni?
Anche per chi vive in città non è difficile osservare nel cielo le coreografie disegnate dagli stormi di storno (e perdonateci il Calembour), un uccello gregario diffuso in quasi tutto il mondo. Ma cosa guida gli storni nei loro movimenti? Come si coordinano con i compagni di volo? In uno studio pubblicato di recente sui Proceedings of the National Academy of Science, tre ricercatori inglesi dell’Università di Warwick suggeriscono che questi uccelli si muovono in modo […]

7:00 AM | The Difference Between Teenage Brains And Adult Brains
Teenagers can look like adults, dress like adults, and even act like adults at times; sometimes, it might be hard to tell the teenagers from adults (and other times it isn't hard at all). But it's also crucial to remember that their brains are wired completely differently. It's long been known that at the end of the day, teenagers just don't think like adults, and that's because the different sections of their brains aren't connected the way they will be once they've matured a little more. Most […]

5:29 AM | Waarom een academicus geen freelancer is, en andersom
Het is zomer: de tijd van festivals, maar ook van wetenschappelijke congressen. Op het Lowlands van mijn vakgebied stippel ik mijn route uit, van grote naam naar veelbelovende nieuwkomer, onderweg vrienden tegenkomend en samen de reeds geziene acts besprekend. Boeiende visualisaties werken inspirerend, en de alcohol vloeit rijkelijk. Behalve dat er niet geheadbangd wordt is het verschil tussen... Lees meer op www.sciencepalooza.nl

3:53 AM | Viral diary: The global rise and near demise of polio
For most places in the world, the sight of children in leg calipers has been relegated to the pages of history. The paralysing effects of the poliovirus have become a thing of the past. The advent of the polio vaccine in the 1960s has seen polio progressively extinguished in well-off regions like North America, Australia […]

1:16 AM | Genius and Einstein: From 'Great Man' to 'Every Man'?
Einstein is the poster child for genius because he was a geniusThe American organic chemist Robert Burns Woodward was a genius; the craft at which he excelled better than anyone else was making molecules, some of which were so complex that nobody before him thought they could be made. While little known to the general public, the perception of Woodward as an authentic genius was widely shared by his students and colleagues, several among whom counted themselves among the leading chemists of […]
