5:03 PM | Traveling off the wheaten path
One thing I discovered pretty quickly is that I am incredibly sensitive to even small amounts of wheat/gluten.  I am finding that this makes traveling with celiac disease a lot more challenging than I ever anticipated.  It is also frustrating as one of my favorite parts of traveling used to be finding all the cool […]

5:00 PM | How to make graphene in a kitchen blender
Don’t try this at home. No really, don’t: it almost certainly won’t work and you won’t be able to use your kitchen blender for food afterwards. But buried in the supplementary information of a research paper published today is a domestic recipe for producing large quantities of clean flakes of graphene.  Read more

7:48 PM | Simulate the transit of extrasolar planets
by @ulaulaman about #exoplanets #planetary_transit #kepler_mission #nasa #astronomy The search for extrasolar planets (or exoplanets) had its first success in 1991 with the discovery of some planets orbiting around the pulsar PSR1257+12(1, 2, 3), measuring the variations of the radio pulses coming from the star. The second important milestone in exoplanet research takes place in 1995, with the discovery around the star 51 Pegasi (a star like our Sun) of a Jupiter-like planet, found at a […]
