2:49 PM | Embrioni scambiati, cosa dice la legge
Il caso del presunto scambio di embrioni avvenuto al centro di procreazione medicalmente assistita dell’ospedale Pertini di Roma, su cui il ministero della Salute, tramite il Centro nazionale trapianti, ha già avviato un ispezione, è del tutto eccezionale. Non è disciplinato né previsto dalle legge, in quanto stiamo parlando di un errore umano – e per il quale le responsabilità andrebbero ricercate nello […]

2:11 PM | The Genetic Legacy of Interbreeding with Neandertals
Publishing a draft of the Neandertal genome (1) opened up whole new avenues to understanding the ancestry of modern humans. No longer constrained to comparing the morphology of fossilized remains, scientists can now delve into the genetic differences between anatomically modern humans and our close relative Homo neanderthalensis. From these genetic studies, we are learning […]

1:38 PM | Emma Castelnuovo, la matematica che vedeva con la mente
Emma Castelnuovo, insegnante e matematica italiana, figlia del celebre Guido, è scomparsa pochi giorni fa nella sua casa di Roma all'età di cento anni. Dopo la laurea, nel 1936, non potè lavorare a causa delle leggi razziali: solo nel dopoguerra riuscì a ottenere la cattedra di matematica al liceo Torquato Tasso di Roma, dove insegnò fino al 1979. Rivoluzionò completamente la didattica, in particolare della geometria euclidea, mettendo "fantasia e […]

1:37 PM | Video Tip of the Week: NaviCell for custom interaction maps for systems biology
The onslaught of sequence data from a whole range of species and tissues continues, and certainly will for a long time. But moving from there to the level of understanding the interactions among the genes that contribute to the structures, behaviors, and phenotypes of the systems requires other types of supporting software. NaviCell is a […]

12:30 PM | Flippase recognition target: orientation matters, so why care?
FRT sites are used often (at least in Drosophila) for inducing deletions or “flipping out” of markers in transgenic constructs. When there are two FRTs sequences in tandem, after inducing flippase the DNA sequence that is between these two sites will be deleted. If two FRT sites are facing each other (or looking away), the […]

12:00 PM | Using Pain To Stop Pain
Biology concepts – desensitization, habituation, counter irritation, cautery, heat sensing, pain, chronic, acute, analgesiaGout usually attacks middle-aged men and the big toe joint is a favorite spot. But it can occur anywhere and in anyone. The accretions or urates build up and clog the joint, causng poor function and intense pain, painful enough that even the weight of a sheet on it at night is too much. Usually the acute attacks are far worse, and become less painful gouty arthritisas […]

11:37 AM | How Anoles Sense Heat
We all know that many anoles species are very good at behaviorally regulating their body temperature by moving from an area that is too hot or too cold to another area that is just right. But how do they actually judge the thermal properties of a particular microsite? There’s been a lot of work on […]

11:17 AM | New agricultural trends to feed the world
The agriculture sector needs to double food production by 2050 to meet growing global populations – a tremendous feat considering the challenges posed by climate change, water shortage and how the increase in farming land is not catching up with demand. That’s why scientists are up to their ears looking for ways to sustainably increase production of crops capable of withstanding different environmental stresses.  Read more

11:15 AM | Spazio, la pipì come fonte di energia elettrica?
Spedire rifonimento nello Spazio, agli abitanti della Stazione spaziale internazionale, è costoso. Tanto costoso: servono fino a 33mila dollari per spedire un chilo di acqua o altri rifornimenti nella bassa orbita. E il costo lievita al lievitare delle distanze dalla Terra, così che future missioni spaziali lontane da queste orbite (basti pensare a una diretta su Marte) dovranno trovare sistemi alternativi per sopravvivere. Un sistema è quello del riclico. Ma come si […]

7:42 AM | Q&A on dynamic documents
At GigaScience one of our major goals is to take the scientific publishing beyond dead trees and static PDFs to a more dynamic and interactive process, much like science itself has embraced the Internet to become more networked and data driven. One way we have done this is by enabling the histories and analyses from papers to be visualized and executed through our GigaGalaxy server (see our recent posting on this), but on top of integrating workflows into our papers through citable DOIs, the […]

7:00 AM | The Cartoon That Launched A Raccoon Invasion
Baby raccoons might look cute, but when they grow up, they start getting a tad unruly. After all, they're wild animals. That's something the Japanese learned the hard way after a popular cartoon encouraged kids to adopt the little critters as pets. When the families tired of them, many were released into the wild although they are not native to Japan. They have been wreaking absolute havoc on the ecosystem ever since. The post The Cartoon That Launched A Raccoon Invasion appeared first on […]

6:16 AM | Confermato il legame tra rame e Alzheimer
Da uno studio targato Fatebenefratelli – Isola Tiberina arriva oggi la conferma del legame tra rame e Alzheimer. La ricerca, pubblicata sulla rivista Annals of Neurology, dimostra che nei pazienti con demenza cognitiva lieve (uno dei fattori di rischio per l'Alzheimer), la presenza di alti livelli di rame non-ceruplasminico nell'organismo aumenta dal 20 al 50% la probabilità che la patologia evolva in malattia di Alzheimer. I risultati aprono ora le porte allo sviluppo di nuove […]
