    An international team of astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (here after, exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

    By developing a new method for measuring isotopic ratios of water and carbon dioxide remotely, scientists have found that the water in Saturn's rings and satellites is unexpectedly like water on the Earth, except on Saturn's moon Phoebe, where the water is more unusual than on any other object so far studied in the Solar System. Above image lower left: Cassini VIMS infrared view of Saturn. Blue is infrared light where water ice...

    The research, led by the University of Plymouth, examined the uptake of nanoparticles by a commercially important mollusc, the great scallop (Pecten maximus). After six hours exposure in the laboratory, billions of particles measuring 250nm (around 0.00025mm) had accumulated within the scallop's intestines. However, considerably more even smaller particles measuring 20nm (0.00002mm) had become dispersed throughout the body including...

    Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles. This shape-shifting has served them well, shepherding jellyfish through more than 500 million years of mass extinctions on Earth. Jellyfish are an ancient and successful group of animals. An in-depth look at the genome of the moon jelly, Aurita aurelia, shows that early jellyfish likely repurposed an...

  • 12/03/18--04:30: Life has a new ingredient
  • Our prehistoric Earth, bombarded with asteroids and lightening, rife with bubbling geothermal pools, may not seem hospitable today. But somewhere in the chemical chaos of our early planet, life did form. How? For decades, scientists have attempted to create miniature replicas of infant Earth in the lab. There, they hunt for the primordial ingredients that created the essential building blocks for life. Somewhere in the hostile...

    Argentine and Spanish researchers have used statistical techniques of automatic learning to analyze mobility patterns and technology of the hunter-gatherer groups that inhabited the Southern Cone of America, from the time they arrived about 12,000 years ago until the end of the 19th century. Big data from archaeological sites located in the extreme south of Patagonia have been used for this study. Atlantic Coast of Isla Grande de...

    The Charter for the Protection of the Byzantine Heritage Monuments was uninanimously ratified after a three-day debate held in Thessaloniki over the weekend. The officials agreed on a framework of commonly accepted principles for the protection of the Byzantine heritage monuments for all states which own and manage monuments of the former Byzantine Empire, which spanned 11 centuries and three continents and whose monuments are now...

  • 12/04/18--03:01: The Invisibility of Hi-viz
  • 8478086085_b5a4e7919b_zUrban archaeology with the Origins of Doha Project

    Over the weekend, hundreds of thousands of people protested in France, demanding that French President Emmanuel Macron resign over increased fuel taxes. These protests have become increasingly violent and draw from anarchist and extremist far right factions, all aligned in working class struggle. The banner that these disparate groups have used to signal their solidarity is the gilets jaunes, the “yellow vest,” a ubiquitous piece of clothing worn by those in construction and industrial labor. Also known as high-vis or hi-viz these vests are part of what is called “PPE,” personal protective equipment and is mandated in jobs that deal with heavy machinery and protect the user against hazardous working conditions. In France, it is mandated that drivers carry one in their vehicle.

    Wikipedia states that Scottish railway workers in the 1960s were the first to wear “fluorescent orange jackets, known as ‘fire-flies’” to keep them safe. Since then, motorcyclists, cyclists, cops, hunters, even chickens wear the reflective vests to direct attention to their presence. Which is ironic, as I’ve often noticed an increased invisibility as a result of wearing hi-viz. (Though this invisibility can help, as previously mentioned, with a bit of productive urban exploration.)

    That the protestors are wearing hi-viz is no accident. This uniform codes the wearer as working class, and hides and homogenizes identity. As Elaine Glaser notes, politicians often don hard hats and hi-viz while simultaneously eroding workers rights, but the contrast between the expensive wool jackets of Macron and his colleagues is stark when compared to the black and yellow worn by the protestors. As an archaeologist, I wear hi-viz while working on construction sites that have active, heavy machinery present. Yet this measure of safety while on construction sites can also contribute to a surprising invisibility while wearing hi-viz on the street. I have never felt so reviled as when walking through the City of London, amongst businessmen in suits, as when I was in hi-viz, carrying a hard hat and walking in steel-toed boots covered in Victorian excrement. Okay, being a punk in Texas might have occasionally come close.

    The protests in France continue. The #giletsjaunes have published their list of demands and have been joined by students and ambulance drivers, amongst others. The list is a mixed bag with a bit of racism thrown in for good measure. The protests stay in France, but perhaps people in hi-viz will be a bit more visible in the future.

    Update: I’ve been told that they’ve moved beyond France, so look for a hi-viz jacket in a locality near you.
