What scientists need is increased scientific understanding in the populace. The whole system screams for this. People need to find science that they enjoy, and keep up on it, and follow it. They need to gain some type of useful knowledge, that they can apply and share.
There're breakthroughs all the time, but most people don't know very much more than adults knew in the 30s or 60s. This really requires that people spend time consuming science literature. What would be nice is if someone was able to read an BBC, FOX, CNN science article (on their topic of interest) and realise that the article was too basic to really explain what was going on.
There's a limit on what people can learn, only so much time to use. The difference between now and the 1930s or 1960s is that the "basics" to start understating any one field of science are now much greater. This serves as a deterrent: why would one invest a lot of time into understanding one field, if that person can only feel some reward (basic understanding of up-to-date science in the field) after months or years of dedication? Few will be inclined to do this - science as an obsessive hobby!
We all know that the jack-of-all-trades renaissance intellectual disappeared a few centuries ago. Some people still mastered several fields, but this kind of people is becoming increasingly rare.
I'll argue that popular science dissipated starting the the 1970s, for the same reason: increased complexity. It's gone, and it's not coming back. Up until then, many separate branches of science still had a small enough corpus of knowledge to allow the dilettante to enter it, understand it, and even add to it. Not so any more. The trend is towards ever-increasing specialization of scientists themselves, and this too is a result of the difficulty of learning all accumulated knowledge. If the scientists themselves must do this, what hope can you hold that the general public can ever be interested in an inevitably frustrating endeavor?
There're many areas of strong debate in society, where people have very strong opinions, but there's almost no one incorporating the scientific information into the debate. Hells, a majority of people seem to be ignorant (in a debate they care about) of simple, foundational stuff.
Areas of strong social debate are usually
political, and the sole requirement to participate in those is the ability to assess our fellow humans. When scientific evidence comes into play it gets presented as an appeal to authority argument. Even in the case of basic stuff like creationism: do you really expect people do do a careful study of the evidence backing evolution, before deciding?
In fact, all science is based to some degree on the appeal to authority argument. Sure, published work is supposed to be testable, but how many people actually test it, and how many just assume that it's right unless
someone else comes up with evidence again it? Several scientific frauds which took years to unmask should answer that.
It's a bit like open-source software: theoretically it's "safer" because you can audit the code, in practice it may well happen that nobody, after the original writer, will even look at it. Certainly the vast majority of users just want something "that works" and couldn't care less about the code.
It's an imperfect world, but we all better get used to it, it's not getting any better.
