7:27 PM | A billion-year monument
More than four and a half thousand years ago, a square was marked in the desert a few kilometers west of the river Nile.  It was a blueprint, writ large, for the construction of what would become mankind’s most enduring achievement.  For the next twenty years, large stone blocks would be hauled into place, one every five minutes, day or night.  Six million tons of stone later, the greatest of the pyramids was complete.  (Image […]

7:00 PM | Latest News from the Universe: LambdaWDM, CMB,Warm Dark Matter, Dark Energy, Neutrinos and Sterile Neutrinos
The new concordance model in agreement with observations: ΛWDM (Lambda-dark energy- Warm Dark Matter). Recently, Warm (keV scale) Dark Matter emerged impressively over CDM (Cold Dark Matter) as the leading Dark Matter candidate. Astronomical evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored baryonic cures do not work at galactic and small scales is staggering. […]

4:00 PM | IAU 311: Galaxy Masses as Constraints of Formation Models
In the era of precision cosmology, we think we can accurately predict the distribution of dark matter in the Universe. However the impact of baryonic physics is still largely unknown and our understanding of galaxy formation must rely on observations. A key advance in recent years has been the ability to enrich studies of the […]

1:18 PM | The Last Word
July 14 – 18, 2014 First we domesticated our pets, says guest David Grimm, and then over a long, long period of time, they civilized us.  For which, thank goodness. Christie had a friend who was dying.  In the meantime, how should he stay alive?  Nice answer: by inviting friends over for a Colorado summer […]

11:30 AM | Cruisin’ Over the Bahamas
I just got back from travel, and now I'm deep into planning my panels for San Diego Comic-Con next week, so at the moment I'm enjoying a slow, broiling panic. But I couldn't pass up the chance to post this breathtaking picture of the ocean around the Bahamas taken by an astronaut on the International Space Station as it sailed over on July 15, 2014:* Yegads. You very much want to embiggen that. The bright lights to the upper left outline Florida (the long glow is from Miami), and you can trace […]

9:25 AM | Apollo 11, 45 anni fa sulla Luna
Quel 24 luglio 1969 il cerchio si chiudeva. Ad aprirlo era stato sette anni prima l’allora presidente degli Stati uniti d’America, John F. Kennedy, quando alla Rice University proclamò ILdiscorso. Quello col quale prometteva al suo popolo la Luna.“Abbiamo deciso di andare sulla Luna. Abbiamo deciso di andare sulla Luna in questo decennio e di impegnarci anche in altre imprese, non perché sono semplici, ma perché sono ardite, […]

9:00 AM | Alpine Cosmology Workshop 2014
The concept of the workshop is to combine a scientific part, in which each participant delivers a review on their topic with a group activity in which every participant is engaged. To this end we have selected to conduct the workshop at several huts located in the Alps, connected by hiking trails. Each day has […]

10:03 PM | Will Science Burst the Multiverse's Bubble?
The idea that there are an infinite number of universes beyond our own is assumed impossible to prove or disprove -- but a new computer model might give us hints as to what evidence to look for. Continue reading →

6:48 PM | “How Can You Talk About Space Exploration at a Time Like This?”
That is the question that a colleague of mine posed in response to the horrific events unfolding in Ukraine, Iraq, and Gaza (not to mention Pakistan, Afghanistan, Tunisia, Burma, and many other places that have been pushed out of the headlines in the hierarchy of bad news). In essence she was saying: “Time for some […]The post “How Can You Talk About Space Exploration at a Time Like This?” appeared first on Out There.

2:04 PM | Salute, il Piano della Prevenzione non va bene
“Diritto dell’individuo e interesse della collettività” secondo la Costituzione, e invece nel nostro paese la salute di almeno sei milioni di persone è a rischio a causa dell'inquinamento. Lo dimostrano i risultati del progetto Sentieri, uno studio coordinato dall’Istituto Superiore di Sanità che dal 2010 analizza gli effetti dell’inquinamento ambientale sulla salute delle persone residenti nei pressi di siti contaminati da impianti industriali […]

12:03 PM | La più dettagliata mappa di Marte
In attesa di raggiungere Marte nel 2030 (come previsto dai piani della Nasa), per ora dovete accontentarvi di pianificare il vostro futuro soggiorno sul Pianeta Rosso. E come ogni buon viaggiatore sa bene, per farlo è fondamentale avere una mappa. Una fortuna quindi che lo United States Geological Survey (Usgs) ne abbia appena pubblicata una, e anche la più dettagliata mai realizzata, in cui vengono raccolte le informazioni collezionate da quattro spedizioni spaziali nell'arco di […]

9:30 AM | Cosmic Duckie, You’re the One ...
(With apologies to Ernie.) Right now, in deep space 400 million kilometers from Earth, the European Space Agency probe Rosetta is easing its way toward the comet called 67P/Churyumov-Gerasimenko (which, for obvious reasons, I’ll just call ChuGer). On July 14 it was a mere 12,000 km (7400 miles) from the comet—less than the diameter of the Earth! It took a series of images of the frozen ice ball, and it’s becoming very clear that this comet is really, really weird: It’s […]

8:00 AM | Mouse Medicine to Combat Lyme
Lyme disease is a growing scourge. The Centers for Disease Control and Prevention receives about 30,000 reports of the disease each year, but agency says the number of actual diagnoses could be ten times higher. Once upon a time, we had a safe and effective vaccine to prevent the disease. But this vaccine, called Lymerix, was withdrawn in 2002, just four short […]
