8:40 PM | Il razzo che ci porterà su Marte
Astrofili, posticipate il conto alla rovescia. La Nasa ha cambiato programmi, posticipando al 2018 (inizialmente era fissato per il 2017) il decollo dello Space Launch System, il successore dello Space Shuttle, un nuovo sistema di propulsione spaziale basato su una tecnologia a combustibile liquido, più sicuro e meno costoso rispetto al propellente solido. Si tratterà del razzo più potente mai costruito, con ambizioni senza precedenti: portare gli esseri umani su un […]

5:10 PM | Adopting Littermates… (Don’t)
The title of this post is a bit strong, but I do want to caution people from adopting two dogs from the same litter because “it’s easier” to raise two at once (ask someone with twins if it’s easier than having one child) or “we don’t want our dog to be lonely.” (Because you might […]

4:00 PM | Factsheet of the month: September – Bacterial wilt management in tomatoes
Last month, SciDevNet reported on a hybrid tomato variety that is encouraging Nepali farmers back into tomato production after the majority of plantations were wiped out by storms and disease 5 years ago. The variety, known as Shrijana, is high-yielding, wilt and disease-resistant and flavoursome. The higher yields have increased farmers’ incomes, thus raising their […]

3:00 PM | Male and Female Anoles that Look Different: Anolis transversalis
We’ve talked previously about anole species that differ in the color of their dewlaps, but I don’t recall any discussion of species in which the males differ markedly in body patterning. Certainly, that happens a lot. For example, we’ve talked a lot about polymorphisms in female back patterns, but in most of these species, the […]

2:31 PM | In alta quota sale anche la pressione arteriosa
Da oggi, alle raccomandazioni già note per chi soffre di ipertensione se ne dovrà aggiungere una nuova: evitare le camminate ad altitudini estreme. Uno studio dell’Università di Milano-Bicocca e dell’Istituto Auxologico Italiano, pubblicato sull'European Heart Journal, dimostrerebbe infatti che la ridotta disponibilità di ossigeno in alta quota può causare un pericoloso aumento della pressione arteriosa nelle 24 ore, e che ad altitudini superiori […]

1:53 PM | "Every piece of art is a reflection of the everyday world": award winning poet Samuel Peralta talks about physics, art, and science fiction.
I've been doing author interviews for a few years now and I always try to limit my questions to 4-5 because I know writers are busy people and so are blog readers. However, today's guest is such an interesting person that I really couldn't refrain from asking more. Samuel Peralta is a physicist, an award-winning poet, a bestselling author, and just a beautiful person to meet and talk to. His work has been recognized with numerous awards, including from the BBC, the UK Poetry Society, Digital […]

1:16 PM | Sansa Stark's portrait in the Uffizi?
Renaissance art is mostly of a religious theme; the rest is portraits of important people. You don't see landscapes except for background details. Some of the frescos in the Uffizi about which they tell you nothing show you much more about the more ordinary life and times. At any rate, a younger relative began the meme of looking for portraits that resemble friends and family members. Thus while never intending to, portraits were being viewed with a new purpose, and much to TPP's surprise there […]

1:05 PM | Thoughts on travel
The Phactors like travel, but not traveling. To be clear travel is when you are at someplace that is not home; traveling is the act of getting to that someplace. Traveling has become drudgery, a necessary ordeal to get to some place different. Nothing about traveling is fun, and it is often quite stressful. Traveling home is more so because there is no anticipation of going someplace new. Airports must be the most inhumane, uninhabitable, uncomfortable, uninspiring, and ugly places that humans […]

12:12 PM | Ebola: speranze dal siero sperimentale
I numeri e la geografia dell’epidemia di ebola che ha colpito l’Africa continuano a far paura. Dopo la segnalazione di nuovi casi in Congo (sebbene qui il contagio sarebbe dovuto a un diverso ceppo diverso da quello che si è abbattuto sull’Africa occidentale), arriva la conferma anche di un caso in Senegal e si teme anche in Europa, per una possibile infezione in Svezia. E con le morti ormai salite a oltre 1.500 accelera la ricerca a una cura per ebola, che passa anche […]

12:00 PM | Pollination by sexual deception in Pterostylis
A single species of male gnat (Mycetophilidae) visits and pollinates the rewardless flowers of P. sanguinea. The gnats often show probing copulatory behaviour on the labellum, leading to its triggering and the temporary entrapment of the gnat in the flower.

Naked Mole RatCredit: UT Health Science Center at San AntonioThe hairless, odd-looking creature in the photo is a naked mole rat (Heterocephalus glaber).Among many weird traits, the species also holds the record for longest living rodent. For comparison, the house mouse (Mus musculus) has a maximum lifespan of just 2-3 years, whereas naked mole rats have been recorded to live as much as 32 years!The exact mechanisms behind the species remarkable longevity have yet to be clearly unveiled, […]

These days I’m having trouble finding time to write, especially to blog.My colleagues and I are busy building a team and a large network of collaborators for a series of related malaria elimination projects.  Our initial goal in this project is to wipe malaria out in very specific populations.  If this works, and from our initial work at a smaller scale it appears as though it can, it will be vastly scaled up – reaching throughout Southeast Asia. The impetus for this work […]

7:14 AM | Una mappa per le strade del futuro
Sulle strade viaggiano le persone sì, ma soprattutto lo sviluppo socioeconomico dei Paesi. Fare nuove strade però non significa solo creare nuovi collegamenti, e dare nuovo slancio all’economia, soprattutto nei paesi in via di sviluppo, ma anche fare i conti con l’ambiente. Dunque, come e dove realizzarle? Per rispondere alla domanda un gruppo di geologi su Nature ha elaborato delle mappe, con l’intento di fornire un punto di partenza per la pianificazione delle […]

7:10 AM | Così i brutti ricordi diventano belli
Ricordate la trama del film Se Mi Lasci Ti Cancello? Nella storia, Clementine, dopo la turbolenta fine di una relazione, si rivolge a una particolare clinica in grado di rimuovere dalla mente di una persona specifici ricordi. Ebbene, uno studio pubblicato su Nature, mostra come il desiderio di Clementine non sia così irrealizzabile in fondo. Alcuni esperimenti condotti sui topi, infatti, mostrano come i circuiti del cervello sono (e possono essere) coinvolti nella modifica dei ricordi. […]

7:09 AM | How The British Stole Their Way Into The Tea Business
For years, England got their tea from China. With the end of the Opium Wars, though, one of their major trade venues had been shut down. They needed another way to get tea, and they needed to know China's secrets to do it. They sent in Robert Fortune, a Scottish botanist, to tour tea factories, discover just how it was prepared, and steal some seeds---which Europeans had never seen. It worked, and he brought tea seeds to India to start their rise to the top of the tea-producing world, after he […]

7:08 AM | Bad memories made good at the flick of a switch
How quickly our memories of people, things and places can change from good to bad if something like a break up happens. Now scientists have worked out how these memories change. And perhaps more importantly, they have turned bad memories into good memories. This builds on previous work showing it is possible to create and […]
