4:38 PM | How a plant molecule is a “superb” sunscreen
    Like us, plants worry about sunburn. Research now shows that a molecule called sinapoyl malate found in plants is one hardworking sunblock. It captures some of the most damaging radiation from the sun. Ultraviolet radiation is split into nine groups. One of the groups is UV-B radiation in the 280 to315 nm range. […]

4:13 PM | "an awesome woman"
Been away from this blog and quite out of touch for a while, but did get the shocking news two weeks ago of the passing of prior NC Zoo Society colleague Kerry Sparks. Can't think of better words than these from another former colleague of Kerry's: "We lost an awesome woman yesterday. Kerry Sparks was a dedicated Mom, beloved daughter and girlfriend. She was the friend you wanted in your corner the colleague you wanted on your team. She juggled any ball we threw at her at Habitat with grace, […]

4:07 PM | Stress, ansia e depressione danneggiano il Dna
Lo stress fa male, si sa. Fino ad oggi però non era chiaro in che modo stress e disturbi collegati, come ansia e depressione, influenzassero il nostro organismo e riuscissero a peggiorare il nostro livello di salute. A fare chiarezza arriva un nuovo studio pubblicato sulla rivista Psychotherapy and Psychosomatics dai ricercatori delle università tedesche di Konstanz e di Ulm, che dimostra come i disturbi da stress creino danni al livello del Dna, peggiorando inoltre la […]

4:03 PM | Funding crisis in basic research
The editorial in our November issue discusses the shortage of funding for basic science in the US and how the ramifications of funding shortfalls on society at large can be measured.  But the US is not alone in facing a much tightened research budget.  Read more

3:28 PM | Pronti per l'arrivo delle gru?
Un appuntamento importante per tutti gli appassionati di ornitologia: le gru sono in arrivo nei nostri cieli. Gli stomi di questi uccelli migratori dal lungo collo, composti da decine, a volte centinaia di esemplari, passeranno infatti nei prossimi giorni sull'Italia lungo la rotta che li porterà a svernare in Francia, Spagna e nell'Africa del Nord. Anche se non siamo la destinazione finale del loro viaggio, anche da noi gli appassionati sono già pronti: Ornitho.it, il più […]

3:26 PM | The 100 most highly cited papers of all time: Tools, not ideas
A rather obscure paper by biochemistOliver Lowry is the most highly citedscientific paper of all time(Image: beckerarchives)Nature has published a comprehensive list of the top 100 most highly cited papers of all time and the list is well worth a look for what it reveals about what's really important in science, what people perceive as being important and in fact how science progresses.I like the list because it confirms something that I have written about on the blog a few times: science is as […]

3:05 PM | One more thing to worry about
That's just swell! The universe could end any time, although the odds are rather low really, but still what a thing to stay awake at night worrying about. After figuring out that the universe was expanding, cosmologists wondered if the universe would end in a Big Crunch, sort of a reverse of the Big Bang, or in a Big Chill, expanding outward forever.  Then the discovery, sort of, of Dark Energy suggested that the universe would end in some sort of particle decay, a Big Rip, something that […]

2:44 PM | Peritoneal Carcinosis and HIPEC: A second chance for patients, thanks to animal research
When we hear the phrase ‘animal research’ we tend to think about the development of new drugs for the clinical practice, or studying molecular pathways involved in the progression of disease; but we must also remember that the techniques used … Continue reading →

2:30 PM | Con la matematica si corre meglio
Un runner che punti sull’allenamento e su una dieta sana ha indubbiamente già adottato dei validi metodi per migliorare le proprie prestazioni sulla pista. Ma potrebbe considerare anche dell'altro per raggiungere un'ottima performance: la matematica. È quanto suggeriscono, in uno studio pubblicato su Siam Journal on Applied Mathematics, due ricercatori del Centre national de la recherche scientifique (Cnrs) di Parigi, secondo i quali le equazioni differenziali […]

1:57 PM | Resourceful Crustaceans Turn Invasive Seaweed into Homes
When a new developer comes to town and starts aggressively building up the empty property around your home, you can get mad—or you can move in. That’s what tiny crustaceans in the Georgia mudflats have done. Facing an invasive Japanese seaweed, they’ve discovered that it makes excellent shelter, protecting them from all kinds of threats. […]The post Resourceful Crustaceans Turn Invasive Seaweed into Homes appeared first on Inkfish.

1:48 PM | Metabarcoding soil and leaf-litter
Today I came across a new very interesting paper published in Ecological Indicators. An international group of researchers used established metabarcoding protocols to compare soil and leaf-litter samples with malaise trap samples in southern China and to compare leaf-litter samples with canopy-fogging and morphologically identified spider samples in central Vietnam.For those that are not so familiar with the term metabarcoding here a text fragment from my most successful blog post ever (sic!): […]

12:00 PM | Release the Kraken!
“Architeuthis, the giant squid, is the quintessential sea monster, probably responsible for more myths, fables, fantasies, and fictions than all other marine monsters combined…[It] surely is the most remarkable unscheduled arrival in the history of zoology, crypto or otherwise. An animal that was believed by many to be mythological verified its existence…” (Ellis, 122, 133-34). Science knows it by the name Architeuthis dux. For centuries, however, it was known by […]

Pale Male is a red-tailed hawk that has lived in New York City for 24 years. He’s managed to survive in the dangerous and poisoned rat--infested environment while seven of his mates have died or disappeared. His hardiness, beauty, and uniqueness have made him a local icon and arguably the most well-known hawk in the world. The post New York City’s Resident Raptor appeared first on KnowledgeNuts.

10:17 AM | Creato il primo mini-stomaco umano
Dopo il rene, il cervello e la vagina, il pool degli organi ricreati in laboratorio si allarga. A partire dalle cellule staminali sono stati infatti prodotti in laboratorio i primi “organoidi gastrici”, riproduzioni tridimensionali e in scala ridotta dello stomaco umano. Secondo gli scienziati del Cincinnati Children’s Hospital Medical Center che lo hanno realizzato - come raccontano in uno studio pubblicato su Nature - questi stomaci in miniatura potranno […]

10:16 AM | Helder en leuk vertellen over ingewikkelde wetenschap – zo doe je dat
Het gaat niet altijd goed: ingewikkelde concepten toegankelijk maken voor een breed publiek. Als wiskundige die werd afgeleid door de wetenschapsjournalistiek, schreef Ionica Smeets een boek over hoe je exacte wetenschap aantrekkelijk kunt presenteren, om zo een breder publiek te bereiken dan alleen vakgenoten. Eerder was Smeets met name bekend als schrijvend wiskundemeisje of getallendiva, maar... Lees meer op www.sciencepalooza.nl

9:36 AM | Pay what you want
Verschillende Nederlandse ondernemers experimenteren met pay-what-you-want betalingssystemen. Een sympathiek concept, maar loont het ook? In Rotterdam opende deze zomer het Geefcafe haar deuren, een Pay-What-Yo-Want (PWYW) restaurant waar je zelf kiest hoeveel je betaalt voor je eten: 20 euro, 10 euro, of gewoon helemaal niets. PWYW is een idee dat langzaam aan populariteit wint, nadat Radiohead... Lees meer op www.sciencepalooza.nl

Nel mare nostrum il pesce spada è ancora pesantemente minacciato. Già sovrapescato, continua a essere un protagonista dello sbarco e della vendita illegale nei mercati italiani e, ancor peggio, paga le conseguenze della mancata azione di recupero da parte dell’Unione Europea. A puntare il dito contro l'Europa e l'Italia in particolare è l'organizzazione internazionale per la protezione degli oceani, Oceana, forte dell’accesso ad alcuni documenti della […]

9:00 AM | Belowground legacies of Pinus contorta invasion and removal result in multiple mechanisms of invasional meltdown
Invasive plants alter plant communities and transform landscapes aboveground, but also have strong belowground effects that are potentially even more important to ecosystem outcomes. In a new study published in AoB PLANTS using management treatments of the widespread invasive tree, Lodgepole Pine, Dickie et al. found that pines and pine removal transform belowground ecosystems, increasing […]
