3:04 PM | Synchronizing mitochondrial metabolism
Mitochondria are fidgeters. That’s what researchers discovered in a recent study. The organelles undergo waves in ATP production. Furthermore, the mitochondria, like synchronized dancers, work in a coordinated fashion. A team at the National Institute of Dental and Craniofacial Research report in a paper just out in the journal Cell Reports that mitochondria in the […]

2:42 PM | Il pericolo di giudicare gli altri dal loro aspetto
"Anche se ci piace pensare che i nostri giudizi e le nostre scelte siano razionali, imparziali, coerenti e basati unicamente su informazioni pertinenti, la verità è che sono spesso influenzati da fattori superficiali e irrilevanti", afferma Christopher Olivola della Carnegie Mellon University's Tepper School of Business di Pittsburgh, negli Stati Uniti, commentando la sua ultima ricerca. In […]

2:25 PM | New Phylogeny for Amazonian Dactyloa Anoles: Multiple Evolution of Horns, Dewlap Color Evolution, New Divergence Time Estimates
In a fascinating new paper, Ivan Prates and colleagues report on a phylogenetic analysis of Amazonian Dactyloa clade anoles with implications for a number of important topics in anole evolution. The authors generated new mitochondrial and nuclear gene data for many Amazonian Dactyloa and combined those data with existing data from previous studies. Of particular note […]

2:17 PM | Wildlife Photography of the Year 2014: gli scatti vincenti
Si stringono gli uni agli altri per superare il freddo della notte i babbuini gelada ritratti in questa foto premiata come “Winning Images” dal Wildlife Photography of the Year2014.

2:12 PM | Paralisi, primi passi dopo un trapianto di cellule
Diverse coltellate sferrate alla schiena nel 2010. Midollo spinale lacerato. Conseguenza: paralisi totale dal torace in giù. La vita di Darek Fidyka, quarantenne polacco, sembrava destinata a proseguire su una sedia a rotelle. Ma un’équipe di scienziati polacchi e britannici è riuscita, sorprendentemente, a ridargli speranza: come raccontano su Cell Transplantation, hanno eseguito un trapianto di cellule dalla cavità nasale di Fidyka al suo midollo […]

2:07 PM | Curiosity Unleashed: Wisconsin Science Festival 2014
“Oh wait Mom, look, bugs!” And she was off. The next thing I knew she had a pale greenish-blue tobacco hornworm caterpillar in her hand. “I’ve never seen anything like this before.” Nor had I. She turned it upside down and started tickling its legs with a finger of her free hand. “What does it […]

2:00 PM | The Art of Science: Claire Moynihan’s Beautiful Bugs
British textile artist Claire Moynihan riffs on traditional insect collections with her “bug balls” – tiny hand-embroideries of insects on felted wool balls. Moynihan uses a variety of embroidery techniques and materials which allow her to produce highly dimensional effects. … Continue reading →

1:46 PM | Video Tip of the Week: SeqMonk
Always on the lookout for effective visualization tools, I recently came across a series of videos about the SeqMonk software. It’s not software that I had used before, so I wanted to look at the videos, and then try it out. It downloaded quickly, offered me an extensive list of genomes to load up, and […]

12:01 PM | Coelopleurus! The most gorgeous urchin you never heard of!
This week, I thought I'd share some gorgeous sea urchin love! Behold Coelopleurus! What's that? You've never HEARD of Coelopleurus??  Well, that's about right, I suppose. Its a distinctive looking enough species but it lives in slightly deeper water than is typical for most casual SCUBA divers or vacationing snorkelers..Described by Louis Agassiz in 1840, Coelopleurus is a genus in the family Arbaciidae. There are about 14 known species. Eleven living species and four fossils. […]

12:00 PM | Should you reply to spamming students?
A colleague, who is a new assistant professor, asked on Facebook, if he should reply to an “endless” stream of emails from international students.I know the kinds of letters this person is asking about. Many show the candidate has extremely limited ability to express him or herself in written English, the tone is often obsequious, and the letters are often clearly “form” letters send to who knows how many institutions.What’s the right course of action? On the one […]

Vi ricordate le secchiate d’acqua dell’Ice Bucket Challange? Bene, dopo la campagna per la raccolta fondi a favore della ricerca sullasclerosi laterale amiotrofica, è di nuovo tempo di sfide virali sul web.

9:17 AM | Viagra: un toccasana anche per il cuore?
La famosissima pillolina blu (il Sildenafil o meglio noto Viagra) utilizzata per risolvere problemi di impotenza, potrebbe rivelarsi utile non solo nell’intimità. Infatti, assumere questo farmaco giornalmente farebbe bene anche al cuore nelle persone che soffrono di ispessimento dei muscoli del ventricolo sinistro o di insufficienza cardiaca precoce. Quasi un ritorno alle origini potremmo dire, per il farmaco inizialmente pensato per il trattamento di problemi cardiovascolari […]

9:00 AM | Was John Snow more of an empiricist than the miasmatists?
If you know anything about epidemiology, you know that the iconic Broad Street pump in the Soho district of London is the site of what is considered to have been the first modern, epidemiological study.  This is where the man remembered as the first epidemiologist, John Snow, in the first empirical study of its kind, demonstrated that cholera is a waterborne disease.  Or at least that's the legend. John SnowThe story is well-known in the field of epidemiology, but also beautifully […]

8:46 AM | Al Gran Sasso il metro cubo più freddo dell'Universo
Ai Laboratori Nazionali del Gran Sasso è record del mondo. L'esperimento Cuore dell'Infn ha infatti portato una struttura di rame di un metro cubo alla temperatura di 6 millikelvin, guadagnando il podio per la massa più grande e voluminosa mai portata ad una temperatura così prossima allo zero assoluto (0 Kelvin). La struttura di rame, del peso di circa 400 kg, è stata dunque per 15 giorni il metro cubo più freddo dell’Universo. Cuore (acronimo per […]

7:00 AM | Why Early Christians Revered Pontius Pilate As A Saint
Calling Pontius Pilate a saint would sound incongruous to modern Christian ears. How can this man, the Roman prefect who ordered Jesus to be flogged and handed him over to be crucified, be considered a saint? Yet, that was exactly how some early Christians viewed him---a Christian convert who was ultimately martyred for his faith. The post Why Early Christians Revered Pontius Pilate As A Saint appeared first on KnowledgeNuts.

5:05 AM | No, Drinking Your Own Urine Will Not Cure Ebola (Or Anything Else)
Fear does strange things to people. The fear du jour currently permeating the US is, of course, the Ebola virus disease. Despite the august efforts to reassure and educate from CDC and the WHO, there has spread a modicum of panic (often with tragic results); we have seen Ebola response become a political issue, and as pointed out recently by that redoubtable scienceblogger, Orac, a ghastly profusion of conspiracy theories and quackery has crawled out of nooks and crannies, feeding...

Gatos negros, serpientes, lechuzas, búhos, ratas, lobos, animales teratológicos, murciélagos, insectos y arañas han despertado sentimientos negativos a lo largo de los siglos y han sido vinculados con las brujas, el mal y el mundo misterioso de la noche.
