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 […]

Continuano le polemiche sulle sigarette elettroniche. Dopo la notizia delle intossicazioni da liquido di e-cig, il Los Angeles Times racconta oggi di un rapporto firmato da undici politici statunitensi, secondo il quale le aziende di sigarette elettroniche stanno mettendo in atto strategie aggressive di marketing per promuovere i propri prodotti ai più giovani. Minorenni compresi. Secondo lo studio, i produttori mettono nomi cool ai gusti […]

5:00 AM | Comments for first half of April 2014
Impact Story looks at what people consider to be obstacles publishing in “megajournals” like PLOS ONE. Their list is good, but it doesn’t have the number one reason I’ve heard for people not submitting there: $$$Excusion Set looks at cranks and the deficit model of science communication. In other words, how can you communicate with someone who thinks you’re wrong?I make a cameo appearance in this post at The Molecular Ecologist on why people sign their reviews of […]

Este pequeño impostor mide alrededor de 8 centímetros, es de agua dulce y es nativo de la cuenca del río Amazonas, Brasil, América de Sur. Es Monocirrhus polyacanthus y pertenece a la familia Polycentridae, un grupo de peces que está asociado a un comportamiento depredador. Es llamado el “pez […]

2:42 AM | Another Puzzle – about the interaction of host and pathogen
Ok, I realize that some of the past puzzles I’ve made either had errors or were simply too obscure in their clues (again, I’m a crossword novice). I tried to be a little more clear with this puzzle and also did my best to force as many clues into actually ‘crossing’ as possible. Let me […]

Today, a cool assortment of unusual videos of brittle stars digging themselves into the sediment!hmm.. yes, I know that doesn't sound all that special but brittle stars are some of the most abundant animals on the planet. In some settings, such as the deep-sea they are thought to comprise an incredible amount of biomass.  As I've written about before, the Amphiuridae, which often make their home in sediment and hiding in mud are among the most diverse groups of brittle stars.For the topic […]

The surgical site is marked on a patient if such marking is appropriate for the procedure. Check. The probe measuring blood oxygen content has been placed on the patient and is functioning. Check.

12:57 AM | Iowan proclaimation calls for prayer and humble repentance
Dear Pastor Grandstand (Branstad or something like that), Thank you for your invitation to join in thoughtful prayer and humble repentance, but for what exactly?  Yes, your proclamation was for Iowa, but surely it would still count just across the river, or is the God you mention a small one?  Is repentance necessary because Iowa has been wicked? But no, you say our nation has “fallen from her intended purpose”?  Hmm, TPP didn’t even know our […]

At the end of March I attended the SOBEFREE foray with amateur and professional bryologists from across California and beyond. I highly recommend attending this foray, especially if you live in California. This year we went to some really great locations in Santa Cruz county and I learned tons of California mosses. The days are spent hiking and collecting mosses with our permits in hand. Then the
