  • Explorers have long known there was more to the 887 statues on Easter Island—some 2,000 miles west of Chile—than just the statue heads made famous in photographs.
  • most people think of the renowned monolithic statues, they think of the heads only
  • October 2011, the Easter Island Statue Project began its Season V expedition, revealing remarkable photos showing that the bodies of the statues go far deeper underground than just about anyone had imagined.

  • Slideshow of the Easter Island excavation photos]
  • technically full-bodied statues have been known to exist on Easter Island for hundreds of years, some of the new petroglyph writings on the recently excavated statues appear fairly unique
  • many statues have individual petroglyphs
  • these and only one other statue—of over 1,000 we have documented—have  multiple petroglyphs carved as a composition on their backs
  • the excavation sites offer some new "strong evidence" of how the Rapa Nui ancestors managed to manipulate the heavy statues into place with limited technological resources
  • wrote that her team has found tuna vertebrae near the bottom of a recent excavation

  • team of Rice University freshmen took a mousetrap and built a better way to treat dehydration among children in the developing world.
  • goal was to regulate the amount of fluid delivered to children so we could prevent over-hydration and under-hydration
  • designed to be used in severely underdeveloped parts of the world, where conditions can be pretty primitive and they may not even have electricity."
  • ...12 more annotations...
  • physicians have mentioned to us that they would like a tool that can better moderate IV-fluid delivery to children, who are often connected to adult IV-bags
  • it is of critical importance that the appropriate amount of fluid is delivered."
  • In understaffed medical settings, monitoring IV-fluid delivery to patients can be a challenge
  • device designed by the IV DRIP team is inexpensive; it costs about $20 to manufacture
  • mechanical, durable, autonomous and simple-to-operate volume regulator that uses a lever arm with a movable counterweight similar to a physician's scale to incrementally dispense IV fluid.
  • uses the change in torque as an IV bag is drained of fluid to set off a mousetrap-like spring that clamps the IV tube and cuts off the flow of saline solution or other prescribed fluids
  • Tests have shown the device dispenses fluid within 12 milliliters of the desired volume in increments of 50 milliliters.
  • device can be mounted on a wall or attached with clamps to a portable hospital IV pole
  • the clamp goes off and it folds the tubing in a V-shape, the way you would crimp a garden hose to make the water stop coming out
  • most time-consuming part of assembling the device was calibrating the counterweight and determining the precise spacing of the notches the counterweight falls into and holds as the fluid drains
  • This summer
  • four of their prototypes to Malawi and Lesotho, respectively, to test them under practical field conditions

Ancient sea reptile with gammy jaw suggests dinosaurs got arthritis too - 0 views

shared by Mars Base on 16 May 12 - No Cached
  • scientists at the University of Bristol has found signs of a degenerative condition similar to human arthritis in the jaw of a pliosaur, an ancient sea reptile that lived 150 million years ago
  • Such a disease has never been described before in fossilized Jurassic reptiles.
  • has been kept since its discovery in the collections of the Bristol City Museum and Art Gallery.
  • ...15 more annotations...
  • 8 metre long pliosaur was a
  • crocodile-like head, a short neck, whale-like body and four powerful flippers to propel it through water in pursuit of prey.
  • huge jaws and 20 cm long teeth
  • this particular individual was the unfortunate victim of an arthritis-like disease.
  • eroded its left jaw joint, displacing the lower jaw to one side
  • evidently lived with a crooked jaw for many years, because there are marks on the bone of the lower jaw where the teeth from the upper jaw impacted on the bone during feeding
  • the animal was still able to hunt in spite of its unfortunate condition.
  • signs on the skeleton to suggest that the animal could have been an old female who had developed the condition as part of the aging process
  • large size, and the fused skull bones
  • possibly female because its skull crest is quite low – presumed males had a higher crest.
  • In the same way that aging humans develop arthritic hips, this old lady developed an arthritic jaw, and survived with her disability for some time
  • unhealed fracture on the jaw indicates that at some time the jaw weakened and eventually broke
  • With a broken jaw, the pliosaur would not have been able to feed
  • They were at the top of their food chains, so there would not have been any predators to take advantage of an aging, disabled pliosaur – except for another pliosaur.
  • You can see these kinds of deformities in living animals, such as crocodiles or sperm whales and these animals can survive for years as long as they are still able to feed

  • new partnership between the European Space Agency and the Faulkes Telescope Project, which will encourage amateur astronomers to look for asteroids
  • providing educational opportunities that will allow students to discover potentially dangerous space rocks, too.
  • ESA’s Space Situational Awareness (SSA) program is part of an international effort to be on the lookout for space hazards – not only asteroids but disruptive space weather and space debris objects in Earth orbit
  • ...14 more annotations...
  • asteroids pose a problem
  • hard to see because they can be very dark
  • can approach rather too close before anyone sees them
  • often spotted only once and then disappear before the discovery can be confirmed.
  • ESA is turning to schools and amateur astronomers to help as part of Europe’s contribution to the global asteroid hunt
  • UK’s Faulkes Telescope Project will become the latest team to formally support the SSA program
  • Spain’s La Sagra Sky Survey, operated by the Observatorio Astronomico de Mallorca, began helping SSA earlier this year
  • The Faulkes project has two telescopes where you can sign up for observing online: Haleakala, Hawaii
  • and Siding Spring, Australia
  • For European students, collaborating on exciting ESA activities and possibly detecting new NEOs is very appealing, as its engagement with one of the world’s great space agencies doing critical scientific work.”
  • While the Faulkes project focuses on schools
  • amateurs will be able to freely access the data archives
  • archives are also open to all, and they work
  • Since starting their SSA-sponsored survey work in January 2010, the TOTAS amateur astronomers have identified hundreds of asteroid candidates, over 20 of which have been confirmed and named.

  • were one spacecraft to fail the entire mission wouldn’t be compromised
  • robots would be deployed from a “mother” spacecraft and spring into action upon landing, tumbling
  • hybrid rovers could also help prepare for future, more in-depth exploration.
  • exploration of small bodies would help unravel the origin of the solar system and its early evolution
  • evaluate the resource potential of small bodies in view of future human missions beyond Earth.”
