1:13 PM | Sesso, le posizioni migliori contro il mal di schiena
Il suo nome scientifico è dorsopatia ma ai più è noto come mal di schiena e, secondo le statistiche, colpisce l’80% delle persone almeno una volta nella vita, rendendo ardue e dolorose le azioni più semplici e naturali: come camminare, stare seduti o fare l’amore. A causa del dolore provato durante l’atto sessuale (provocato dalle posizioni assunte della colonna vertebrale), circa l’84% degli uomini e il 73% delle donne con mal di schiena […]

12:55 PM | Chatbots are boring. They aren’t AI.
You know I’m a bit sour on the whole artificial intelligence thing. It’s not that I think natural intelligences are anything more than natural constructions, or that I think building a machine that thinks is impossible — it’s that most of the stories from AI researchers sound like jokes. Jon Ronson takes a tour of…

12:30 PM | BHL Valued by Historians
Many people tend to think of BHL as a resource for scientists. While it’s true that scientists use BHL to find species descriptions and data about earth’s flora and fauna, they are not the exclusive beneficiaries of this wealth of knowledge.BHL contains more than half a millennia's worth of records about the discovery of life on our planet. It is valuable both for the raw data it provides and for the context and history it relates. It is not just a repository of biodiversity […]

12:00 PM | Diversity in STEM: it matters
Diversity in the sciences is a recurrent topic on this blog (and – well – basically everywhere). Scientific American has an excellent overview on what “diversity” is and why it matters to the STEM fields. So whether you think about these issues a lot or a little, I highly recommend reading “Diversity in STEM: What […]

11:54 AM | Russians save cat stuck in car springs (Video)
Every cat-owner knows that our furry friends tend to get trapped in all kinds of obscure places, but very few have probably survived a ride like the one you are about to read.About four months ago, Vitaliy Bouranin left with his Toyota Land Cruiser for a business trip somewhere in Russia. After about 50 miles, running at speeds of over 120 km/hour, he made a stop to get a refill. Until then, he had noticed nothing strange with his car. But this is when things started to get weird. As he […]

Symmetry seen in a butterflyImage source: www.vicvapor.com Have you ever wondered why you are sometimes attracted to some piece of art, and not to the other? Or why you find something visually appealing while another almost repulsive. Well next time, you do find yourself in such a situation, just take a moment, and see if what you are staring at, is symmetric or not. If you like it, chances

9:44 AM | Star Performance Staying connected is vital for our brain cells....
Star Performance Staying connected is vital for our brain cells. Across a mass of 100 trillion bridges, called synapses, neurons combine to give our brain an unrivalled computing power. But there can be too much of a good thing, and too many active synapses can cause damage to the nervous system. The cognitive and muscular problems caused by Huntingdon’s disease are thought to be triggered in this way. Sufferers produce an abnormal version of a protein, a defect that causes the brain to […]

8:19 AM | Cosmesi, lo squalano è ecosostenibile
Lo squalene è un idrocarburo scoperto originariamente (il nome in effetti potrebbe suggerirlo) all'interno dell'olio di fegato degli squali. Dalla sua lavorazione si ottiene invece lo squalano, ingrediente fondamentale di prodotti cosmetici come creme idratanti, olii per bambini e detergenti per il viso. Sulla rivista ChemCatChem, un team di ricercatori dell’Istituto per lo studio dei materiali nanostrutturati (Ismn) del Cnr di Palermo, coordinati da Mario Pagliaro, in […]

8:00 AM | Genome downsizing and karyotype constancy in diploid and polyploid congeners: a model of genome size-variation
In several genera evolutionary chromosome change involves variation in DNA amount in diploids and genome downsizing in polyploids. In a new study in AoB PLANTS, Poggio et al. analysed the genome size and karyotypical parameters of Hippeastrum species with different ploidy levels.The constancy of bimodal karyotypes, even with changes in ploidy level, and DNA content […]

7:56 AM | Young blood cures aged hearts
Young blood can reverse age-related heart disease in mice. Maybe vampires had the right idea. As we age, the chance of developing heart disease gets much higher. Heart disease is the number one killer worldwide. Older people are much more likely to have thickened hearts with bigger cells, a process that is called hypertrophy. Hypertrophied […]

7:00 AM | The Tragic Tale Of Victor Jara’s Last Song
On September 11, 1973, residents of Santiago, Chile awoke to chaos. Fighter jets were bombing the president’s palace, tanks had taken to the streets and ordinary Chileans were being rounded up and tortured in the city’s sports stadiums. One of those detained was folk singer Victor Jara, whose incarceration, mutilation, and brutal murder would come to symbolize the tragic cruelty of the Pinochet regime.

6:38 AM | La storia nascosta di Stonehenge
Stonehenge è un monumento simbolo dell’Inghilterra. Eppure sembra che dopo secoli di ricerche siano ancora molti i segreti nascosti tra le sue pietre megalitiche. Un recente studio dell’Università di Birmingham ha analizzato infatti il terreno che circonda il complesso, scoprendo che nel lontano passato il circolo di pietre non era il monumento solitario che possiamo osservare oggi, ma rappresentava invece il fulcro di un complesso sistema architettonico, che […]

3:34 AM | Of Terms in Biology: Metagenomic Binning
by Christoph Weigel | Summer's almost gone. Imagine you're strolling along the shores of a lake enjoying nature's colors during sunset. Sparkle catches your eyes where the lake languidly laps against the shore. You start pondering whether microbes — and if so which ones, and how many different — cause these glistening, somewhat slimy foam flakes at the shore. Sure enough, you take samples!

9:43 PM | The solution to the research funding problem is simultaneously obvious and nigh impossible
American National Public Radio has been running a series about the state of funding for basic medical research. Today’s entry was When scientists give up.Scientists hear these sorts of stories routinely. What bugs me about them is their faux simplicity.American federal government reduces money for research.Scientists issue dire warnings of bad effects of cuts.Most articles stop there. The implication always seems to be, “More money will fix everything! So give us more!” I am […]

9:17 PM | Soggy September weather
Usually September is a fairly dry, fairly nice weather month. August had above average rainfall, so things entering September were not too dry. TPP made the observation 3 days ago that some rain would be nice or a few things would need some watering.  Hoo boy!  With a total rainfall approaching 4" in the past 48 hours, everything is well watered now OK. Usually this time of year the lily pond needs some topping up, but now a couple of inches will have to be drained off. […]

4:00 PM | Oxidative Stress and Epigenetics: a Novel Link Established Through Histone Adduction
Damage to cellular macromolecules caused by reactive oxygen species (ROS) produced during oxidative stress contributes to the pathogenesis of many disease states. One target of ROS is the 1,4-diene structure of polyunsaturated fatty acids (PUFAs), which is highly susceptible to peroxidation. An important outcome of lipid peroxidation is the generation ...

  Last month I was lucky enough to attend the Xenopus meeting, which took place at the Asilomar conference grounds, close to Monterey, California. This meeting was fantastic, combining great science with a great venue. As there is already someone lined up to write about the scientific aspects of the meeting, I thought I would focus here instead on the […]

2:49 PM | Una terapia precoce contro l'autismo?
La cautela è d’obbligo, considerando la complessità del disturbo così come quella della sua diagnosi. Ma la ricerca, e soprattutto i risultati dello studio dell’University of California Davis Mind Institute, sono di quelli che fanno riflettere, discutere, e anche sperare. Gli scienziati hanno infatti osservato che identificando molto precocemente i bambini a rischio di sviluppare disturbi dello spettro autistico (Dsa) – già intorno ai sei mesi in […]
