Mars Caves, Paracast, Oregon Vortex

Some interesting links I've found this week:
• Cave Skylights on Mars – Images released from the Mars Reconnaissance Orbiter HiRISE team included a black spot, one of seven possible entrances to subterranean caves identified on Mars.
• The Paracast – This webcast, hosted by Gene Steinberg and David Biedny, covers the world beyond science – UFOs, poltergeists and strange phenomena – in a refreshingly level-headed, no-nonsense manner. Many archived shows available online for free.
• Mystery of the Oregon Vortex – Vortexes are one of many secrets of this planet. One of them is the Oregon Vortex which has many paranormal effects. Naturally the phenomenon has been debunked and declared a hoax and an illusion. However, don't believe everything they tell you!
