Gamma rays unlikely to originate from Dark Matter

If we can not use gamma rays to detect Dark Matter what can we use?

Studies by two independent groups from the US and the Netherlands have found that gamma ray signals from the inner galaxy come from a new source rather than from the collision of dark matter particles. The new source is likely to be rapidly rotating pulsars, rather than the as-yet undetected invisible dark matter particles thought to make up 85 percent of the mass in the Universe.

They are not saying you cannot detect dark matter through gamma rays. They are saying that a particular signal, for which DM was a possible explanation, does not originate from DM.

Besides that, there are still many other possible DM signals.

That is the question Orodruin, what can or do we use for detecting DM

Well, so far nothing we have tried has worked (apart from all the gravitational evidence). There are numerous ways of looking for it though. You can look for indirect evidence from DM annihilation products by searching for excesses of positrons, gamma rays, or neutrinos in different cosmic environments. You can look for direct dark matter collisions with matter. You can try to produce it in particle accelerators.
