Are these magical powers real? My interest was caught by an article talking about the mundane and supermundane powers which are mentioned in the Samaññaphala Sutta (The Fruits of the Contemplative Life,  DN 2):

The first five mundane powers: (can be attained through perfection of samādhi)


Supranormal powers 



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, he directs and
  inclines it to the modes of supranormal powers. He wields manifold supranormal
  powers. Having been one he becomes many; having been many he becomes
  one.  He appears. He vanishes. He goes unimpeded through walls, ramparts, and
  mountains as if through space.



Clairaudience



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, he directs and
  inclines it to the divine ear-element. He hears -- by means of the divine ear-element, purified and surpassing the human -- both kinds of sounds: divine and human, whetever near or far.



Mind Reading



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, he directs and
  inclines it to knowledge of the awareness of other beings. He knows the
  awareness of other beings, other individuals, having encompassed it with his
  own awareness.



Recollection of Past Lives



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, he directs and
  inclines it to knowledge of the recollection of past lives. He
  recollects his manifold past lives, i.e., one birth, two births, three births, four, five, ten, twenty, thirty, forty, fifty, one hundred, one thousand, one hundred thousand,
  many aeons of cosmic contraction, many aeons of cosmic expansion, many
  aeons of cosmic contraction and expansion, [recollecting], 'There I had such a
  name, belonged to such a clan, had such an appearance.



The Passing Away &amp; Re-appearance of Beings



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, he directs and
  inclines it to knowledge of the passing away and re-appearance of beings.


One supermundane power (Can be attained through Vipassana): 


The Ending of Mental Fermentations



  With his mind thus concentrated, purified, and bright, unblemished, free from
  defects, pliant, malleable, steady, and attained to imperturbability, the monk
  directs and inclines it to the knowledge of the ending of the mental fermentations.


However, the Buddha emphasized to attain only the last through the realization of Arahatship. It might be unfair to ask for scientific proof, but is there any backup for the first five supposedly attainable powers, any personal experiences maybe?
Some of these have been actively researched in Parapsychology. The Wikipedia link directs you to research efforts around this subject.

If you are skeptical of what others have to say you can verify your self by developing the Jhanas. Also keep in mind more you long for these powers more further it becomes so your practice should be very diligent with strong sense of equanimity through out the practice. Once you see for yourself (Ehipassiko) your doubts and skepticism will disappear.
