11:30 AM | Did a Meteorite Impact in Nicaragua over the Weekend?
Stories are coming out of Managua, Nicaragua, that a large bang was heard by residents there Saturday evening, and it registered on seismic detectors as well. A crater was found in the woods measuring something like 12 meters (40 feet) across. Claims are being made that this was a meteorite impact, a space rock a meter or so across slamming into the ground at high speed. … but I’m unconvinced. Reports are still a bit sketchy, but my biggest doubts come in two parts: 1) In a city of […]

10:30 AM | Week 16: Into Washington State
A waxing gibbous moon rises over the fields at Cherrywood Vineyards. Think Washington is exclusively rainy skies, overpriced coffee and grunge rock? Think again… Well, this past week we’ve wrapped up our Idaho adventures after a brief journey eastward to Wallace and the Center of the Universe and crossed the Evergreen State.  And while Seattle [...]

9:54 AM | Prove tecniche di telepatia
La chiamano telepatia e finora è stata un miraggio. In realtà lo è ancora, ma secondo un esperimento presentato sulle pagine di Plos One, è possibile far comunicare direttamente e a distanza (5 mila miglia) due cervelli – umani – trasmettendo informazioni tramite internet. È la prima volta che gli scienziati riescono a realizzare questo tipo di comunicazione cervello-cervello in modo non invasivo, senza dover parlare o scrivere. Come spiega Alvaro […]

8:00 AM | Why Archeologists Hate Indiana Jones
The jungles of the Peten are hot and sweaty. Most of the best places for archeology are. Field seasons are especially hot, since they are always during the driest time of year so that the site doesn’t get flooded. Howler monkeys boom from the parched trees, which barely twitch during the windless days. Meanwhile, pasty grad […]

6:43 AM | Scoprire il tumore al polmone dalla temperatura del fiato
Il cancro al polmone è uno dei cosiddetti “big killer”, cioè i tumori che ogni anno fanno più vittime a livello mondiale. In Europa si stima ad esempio che ogni due minuti qualcuno muoia di tumore al polmone, mentre in Italia ogni anno la malattia colpisce circa 38.000 persone, provocando 34.000 decessi. Una mortalità altissima, dovuta almeno in parte alla mancanza di programmi di screening (ancora in fase di approvazione sia in America che in Europa) che […]

5:00 AM | L’origine del flusso X nella ‘Bolla Locale’
In media, una volta ogni 100 anni nella Via Lattea accade che una stella massiccia esploda, dando luogo ad una supernova. Si tratta di un evento estremamente energetico che sprigiona in un uno o due secondi una enorme quantità di energia, superiore a quella che il Sole emette nel corso di un milione di anni. […]

4:24 AM | Growth. Peak. Collapse. Planetary exploration from 1959 - 1989
The first three decades of planetary exploration tell a story that sounds all-too-familiar to modern day space advocates. Growth, peak, and then collapse of hard-earned capability. This is the story of planetary science for the first half of its existence.

10:25 PM | Messier Monday: The Teapot-Dome Cluster, M28 (Synopsis)
“The most difficult thing is the decision to act, the rest is merely tenacity. The fears are paper tigers. You can do anything you decide to do. You can act to change and control your life; and the procedure, the process is its own reward.” -Amelia Earhart While the summer may be coming to an…

10:00 PM | Time Limit In Trade Secret Theft Case Results In Dismissed Charges Against Raytheon.
Like most causes of action, trade secret theft has a statute of limitations.  This means that you must file a lawsuit before the time expires. For example, a federal district court judge in Arizona dismissed most of the trade secret theft claims made by Ordnance Technologies Inc. against Raytheon Co. because OTS did not sue … Continue reading →

6:29 PM | Rosetta Reveals Tip of the Comet 67P Knowledge Iceberg
Mapping Comet 67P/Churyumov-Gerasimenko If you’ve ever wondered about the surface of a comet — and why not? — wonder no more. The Rosetta mission has figuratively ripped the fuzzy veil away from Comet 67P/Churyumov-Gerasimenko (Comet 67P for short) mapped its surface, and done preliminary analysis of what that surface is like. That’s just for starters! It turns […]

4:00 PM | Can You Get My Satellite Down From There….Please.
With the ever growing commercial/private space operations, it was inevitable that someone would start talking about salvaging some of the space junk orbiting the Earth. Israeli startup Effective Space Solutions (EFS) has an idea on how to help stranded satellites either getting back up into space, or coming down for the fall. Creidt EFS The … Continue reading →

1:13 PM | Stasera torna la superluna
Sapevate che il termine Lunedì deriva dal latino “lunae diem”, che significa “giorno della Luna”? Non poteva quindi capitare in data migliore la terza superluna dell'estate che, nei cieli italiani, sorgerà stasera, lunedì 8 settembre 2014, intorno alle 19 (l'ultima l'avevamo osservata nella notte di San Lorenzo). Quella di oggi però sarà particolare visto che raggiungerà il perigeo (fase in cui è più vicina al […]

11:30 AM | When Will Betelgeuse Explode?  
If there’s one star in the sky people know about, it’s Betelgeuse*. Marking the right shoulder of the hunter Orion — remember, he’s facing us, so it’s on our left — this orange-red star is one of the brightest in the night sky. It’s been studied for as long as we’ve had telescopes, yet for all our advanced technology and knowhow, details about it are maddeningly vague. We don’t even have a good determination of how far away it […]

10:12 AM | Scuola: troppe diagnosi di disturbi dell'apprendimento
“Oltre 90 mila alunni con DSA tra gli anni scolastici 2010/ 2011 e 2011/2012, 24.811 certificazioni in più (+37 per cento). L’incremento più significativo alle superiori, il numero più alto di studenti alle medie”. Un trend in salita come si evince anche dall’allarme che è stato lanciato a Pisa: “… la dislessia rischia di diventare un’emergenza sociale ... nel 2013 all’ ASL 5 sono arrivate 530 richieste di valutazione […]

8:41 AM | È di un coleottero il bianco più bianco
Dopo il nero più nero (di cui abbiamo parlato in questo articolo), ecco il bianco più bianco: quello del coleottero del sud-est asiatico Cyphochilus. Una ricerca pubblicata su Scientific Reports ha infatti individuato le ragioni del bianco brillante di questi insetti nel modo in cui la luce è riflessa e diffusa dalle sottili scaglie che li rivestono, grazie a una peculiare geometria molecolare. La percezione dei colori dipende dal modo in cui l'oggetto che stiamo osservando […]

This was first published in Dec 6, 2011, and Cameron wasn’t yet an LWONer, she was a guest. She was like those few rare house guests who are so congenial and charming you wish they would just move in, and luckily, she agreed to.  Also her mom sounds like a doll. I’m not sure exactly […]

7:19 AM | Sei mosse per ridurre il consumo di acqua
Avete mai pensato a quanta acqua si risparmierebbe chiudendo il rubinetto ogni volta che ci si lavano i denti? Se non lo avete mai fatto questo è il momento giusto. Secondo una ricerca pubblicata su Nature Geoscience, un utilizzo più parsimonioso nel consumo domestico di acqua, unitamente ad altre “piccole” accortezze, permetterebbe di soddisfare il bisogno idrico globale entro il 2050. Sì, ma come? La scarsità d'acqua non è un problema che […]

4:01 AM | Talk : Living on frack-tured Earth
A recent Nottingham Skeptics event featured a fascinating talk by Dr Hazel Gibson. The talk was entitled "Living on frack-tured Earth" and looked at Dr Gibsons research into the public perception of geology - or, more specifically, hydraulic fracturing (fracking). This post begins with a summary, so far as NSB's notes and Tweets allow, of what Hazel said -and then continues with a bunch of stuff the NSB dug up while reading around the subject:HAZEL'S TALK Hazel began by pointing out that while […]

4:00 AM | I ‘sapori’ della materia scura
Secondo i dati più recenti, sappiamo che oltre l’80% della materia presente nell’Universo è sconosciuta. Ad essa, gli astronomi danno il nome di materia scura che finora nessuno è mai stato in grado di rivelarla nemmeno con i migliori rivelatori a terra. Nonostante ciò, l’unica risorsa che ci permette di determinare la sua presenza è […]
