SELECTION LIMITS: HAVE THEY BEEN REACHED WITH PIGS?

Stars ’ - Have They Been Discovered ?

Recently there is a suggestion about the star RXJ1856.5−3754, being a possible candidate for quark star. While from the estimates of the radiation radius, given by the authors, it does not seem to fit with any of the known models for such stars, the mass radius diagram admits the possibility of this being a quark star of mass M ⊙ < M < 1.4M ⊙ , provided the radius mentioned is the actual radius...

Strange Stars ’ - have they been discovered ?

Recently there have been controversial claims about the nature of the isolated compact star RXJ1856.5−3754, with one group claiming it to be a strange star (Drake et al., 2002) while the other asserting it to be a normal neutron star (Walter & Lattimer, 2002). The controversy arises mainly due to the distance estimate, which in turn is used to resolve the measured angular diameter, and thus the...

Asking photons where they have been.

We present surprising experimental evidence regarding the past of photons passing through an interferometer. The information about the positions through which the photons pass in the interferometer is retrieved from modulations of the detected signal at the vibration frequencies of mirrors the photons bounce off. From the analysis we conclude that the past of the photons is not represented by c...

Have the “mega-journals” reached the limits to growth?

A "mega-journal" is a new type of scientific journal that publishes freely accessible articles, which have been peer reviewed for scientific trustworthiness, but leaves it to the readers to decide which articles are of interest and importance to them. In the wake of the phenomenal success of PLOS ONE, several other publishers have recently started mega-journals. This article presents the evolut...
