4:11 PM | ...and then there were two
The tephritid fruit fly genus Bactrocera is very large and contains about 500 described species. One of those, the oriental fruit fly, Bactrocera dorsalis, is considered a very destructive pest of fruit in all areas it occurs. It is established in numerous regions in Asia, and is often intercepted in the United States, sometimes reestablishing infestations that were previously eradicated. The species belongs to a species complex that contains almost 100 morphologically very similar taxa.

4:00 PM | Halloween Special: First record of bat-pollination in Tillandsia
Bats are responsible for pollinating several species of plants. A new paper in Annals of Botany reports for the first time bat-pollination of a species in the genus Tillandsia. Bromeliaceae is a species-rich neotropical plant family, of which Tillandsia is the most diverse genus and includes more than a third of all bromeliad species. The […]

3:14 PM | NS1: It’s all about location, location, location
  Viruses are minimalists when it comes to genomic data. This light packing of genetic information requires that every protein the virus codes for needs to be as versatile as possible. The flavivirus genus is no exception to this; its genome encodes for three structural proteins (capsid, membrane, and envelope) and seven nonstructural proteins (NS1, […]

2:01 PM | Il carisma è nella voce
Tralasciando rare eccezioni, da sempre i grandi capi di stato sono, oltre che acuti strateghi, anche abili oratori. Una recente ricerca della University of California DI Los Angeles (Ucla) presentata al 168° Meeting of the Acoustical Society of America (Asa) ha rivelato le basi scientifiche di questo legame, mostrando come il carisma esercitato dipenda fortemente dalla frequenza della propria voce. Se si pensa a Martin Luther King, si torna subito indietro con la propria mente al 28 agosto […]

12:06 PM | Perché mangiare cachi fa bene
È originaria della Cina, ma pare avere trovato il suo habitat ideale anche sulle sponde del Mediterraneo. Si tratta della pianta di cachi (Diospyros kaki l.) che oggi, non a caso, viene ampiamente coltivata in Spagna: nel 2012 ben 9.560 ettari sono stati dedicati al frutto dal caldo colore rosso aranciato, di cui oltre l’80% coltivati nella regione di Valencia. Forse è per questa ragione che l’Università di Valencia ha condotto uno studio sui benefici del […]

12:00 PM | The Beautiful Monster: Mermaids
In 1492, Christopher Columbus sailed out from Spain with a mission to find a western trade route to Asia. Instead, he found a whole “New World”…and something altogether more mysterious.On January 9, 1493, near the Dominican Republic, Columbus spotted three “mermaids.” How did he describe them? “They are not as beautiful as they are painted, since in some ways they have a face like a man.”The myth of a marine human extends as far back as 5,000 BCE, when […]

11:34 AM | Non perdiamoci la vista. Campagna per le maculopatie
Le maculopatie sono malattie progressive che determinano una gra­ve compromissione della visione centrale fino all’ipovisione e alla ce­cità. La più diffusa è la Degenerazione Maculare Legata all’Età, che generalmente può presentarsi dopo i 55 anni. Rappresenta una delle cause principali di ipovisione e cecità nel mondo occidentale. Già dai primi sintomi è possibile rallentarla. Una diagnosi precoce è di […]

L’artrite psoriasica è una patologia infiammatoria cronica che colpisce le articolazioni, associata alla psoriasi. È una malattia progressiva che porta piano piano al blocco delle articolazioni e alla perdita di tessuto osseo. In Italia colpisce l'1% della popolazione, circa 600mila persone. Che spesso arrivano a essere diagnosticate, e quindi curate, con un ritardo di 3-4 anni rispetto all'esordio dei primi sintomi. Insieme a Ignazio Olivieri, presidente della […]

8:48 AM | C'è un nuovo legame chimico
La sua esistenza era stata ipotizzata quasi trenta anni fa, ma fino ad oggi era considerato una sorta di mito scientifico. Ora invece un team di ricercatori della Freie Universität di Berlino e dell’Università cinese di Shanxi ritiene di averlo finalmente identificato, almeno sul piano teorico: un nuovo tipo di legame tra molecole, che viola alcune delle leggi fondamentali della chimica tradizionale.

8:06 AM | La reazione all'ebola è scritta nei geni
È la peggiore epidemia della storia. 10mila contagi, 5mila morti. Cifre che, purtroppo, sembrano destinate a salire. Ebola fa ancora tanta, tantissima paura. Ma qualcosa, fortunatamente, si muove: gli scienziati italiani di Okairos stanno cercando di mettere a punto un vaccino, e sempre in Italia si sta sperimentando un farmaco per bloccare le terribili emorragie provocate dal virus. Ma non basta. Bisogna conoscere bene il proprio nemico, come ammoniva Sunzi: un'équipe di […]
