Washington, D.C.— Meteorites hold a record of the chemicals that existed in the early Solar System and that may have been a crucial source of the organic compounds that gave rise to life on Earth. Since the 1960s, scientists have been trying to find proof that nucleobases, the building blocks of our genetic material, came to Earth on meteorites. New research, published next week in the Proceedings of the National Academy of Sciences, indicates that certain nucleobases do reach the Earth from extraterrestrial sources, by way of certain meteorites, and in greater diversity and quantity than previously thought.(more…)
So you’re planning a trip to the ‘city of lights’, Europe’s most romantic city! Although the prospect of seeing famous sights such as the Louvre, Eiffel Tower, Notre Dame and Sacré Coeur is an exciting one, here are a few tips to keep in mind both before setting off and during your stay in Paris.(more…)
The NASA Mars rover Opportunity has gained a view of Endeavour crater from barely more than a football-field’s distance away from the rim. The rim of Endeavour has been the mission’s long-term goal since mid-2008.
Endeavour offers the setting for plenty of productive work by Opportunity. The crater is 14 miles (22 kilometers) in diameter — more than 25 times wider than Victoria crater, an earlier stop that Opportunity examined for two years. Observations by orbiting spacecraft indicate that the ridges along Endeavour’s western rim expose rock outcrops older than any Opportunity has seen so far. The selected location for arrival at the rim, “Spirit Point,” is at the southern tip of one of those ridges, “Cape York,” on the western side of Endeavour. (more…)
Animal’s brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain’s ‘map’ of space is surprisingly flat, according to new research.
In a study published online in Nature Neuroscience, scientists studied cells in or near a part of the brain called the hippocampus, which forms the brain’s map of space, to see whether they were activated when rats climbed upwards. (more…)

*The first Microsoft Home was built in 1994 to show people how technology could transform everyday experiences, and now years later, the reinvented full-scale model home continues imagine a future in which interacting with computers is as comfortable as coming home.*
REDMOND, Wash. – Aug. 8, 2011 – If there’s no place like home, there’s definitely no place like the Microsoft Home.
There’s a doorbell, but a palm-scan or mobile phone will also open the front door. Sensors let you know your plants need watering. You can check the inventory of your fridge and pantry via your phone while you’re out shopping. Grace, the home’s computer, will even help you check on your grandmother, remember to take your medicine, study up for a big anatomy test, or make focaccia without the need for a recipe book.
“Grace, what’s up?” asks Microsoft Home tour guide Jonathan Cluts once inside the front door. A pleasant-voiced computer responds with updates about appointments, messages, and even information about the weather, traffic and the electric scooter that is charging outside the front door. (more…)
Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others, according to a study by scientists at Woods Hole Oceanographic Institution (WHOI).(more…)
Organisms discovered by Yale undergraduates growing within fungi in the Amazon Rainforest can degrade polyurethane, a findings that may lead to innovative ways to reduce waste in the world’s landfills.
The paper, accepted for publication in July by the journal Applied and Environmental Microbiology, is the work of undergraduates who participated in Yale’s Rainforest Expedition and Laboratory course, funded by the Howard Hughes Medical Institute. (more…)
