Title: Japanese researchers break 41 out of 64 steps of SHA256 with preimage attack.
Abstract: In this paper, we propose preimage attacks [...]

sensationalist 6/10
Do you not understand all scientific papers use propose?

Propose as in "You can do it this way that we discovered"

Not propose as in "We think"

I think he means that you should evaluate the actual preimage attack that they propose before saying that they broke it.
I mean i can propose an attack: Search for all the possible keys one by one... This is a nice theoretical attack but has no value in the real world...

You could make a start on this attack by convincing people to pool their resources, perhaps by offering a financial incentive (maybe some bitcoins for contributing computing power)? People could even work on creating some sort of application specific hardware to efficiently search for SHA-256 hash values. You could structure it so that rewards are payed out proportionally to each persons contribution.
