The old adage of the title has a parallel in the scientific world "all research leads to biomedical advances". The fact that research in one discipline contributes to another is well understood by the scientific community. It is not, however, so clear to the public or to public policy-makers. (46)Because public support for funding of biomedical research is strong, the scientific community could build a more effective case for public support of all science by articulating how research in other disciplines benefits biological medicine.The time is ripe to improve public appreciation of science. A recent National Science Foundation survey suggested that Americans continue to support research expenditures. In addition, public opinion polls indicate that scientists and science leaders enjoy enviably high public esteems. (47)Instead of lamenting the lack of public understanding of science, we can work to enhance public appreciation of scientific research by showing how investigations are in many areas close-knit and contribute to biomedical advances.A crucial task is to convey to the public, in easily understood terms, the specific benefits and the overall good that result from research in all areas of science. Take, for example, agricultural research. (48)On the surface, it may appear to have made few significant contributions to biomedical advances, except those directly related to human nutrition.This view is incorrect, however. In the case of nutrition, the connections between agricultural and biomedical research are best exemplified by the vitamin discoveries. (49)At the turn of the century, when the concept of vitamins had not yet surfaced and nutrition as a scientific discipline did not exist, it was in a department of agricultural chemistry that the first true demonstration of vitamins was made.Single-grain feeding experiments documented the roles of vitamins A and B. The essential role of some minerals (iron and copper) was shown later, and these discoveries provided the basis of modern human nutrition research. (50)Despite such direct links, however, it is the latest discoveries that have been made in agricultural research that reveal its true importance to biomedicine.Life-saving antibiotics such as streptomycin were discovered in soil microorganisms. The first embryo transplant was made in a dairy cow, and related research led to advances in the understanding of human reproduction.

There comes a time when all monopolies falter. Think of telecoms operators or utilities, for example. For Google, too, its near-monopoly on search ads will someday end. The company is nowhere near this point yet, of course. But recently there have been signs that Google is no longer quite as untouchable as it once was. Start with online ads. The market for digital advertising has weakened recently. According to IAB, US digital ad spend grew 14 per cent in the second quarter. Not bad. But that was the lowest rate of growth in two years. More concerning still for Google is that search ads" share of the digital advertising pie has been shrinking since 2011. Google is still outgrowing the market —revenues from its own sites, including YouTube, grew 20 per cent in the most recent quarter. But the move away from search is starting to hurt: Bernstein estimates that Google search revenue growth slowed to 17 per cent. Google"s fastest-growing source of revenue has become its lower-margin " other" category, which includes sales from Google Play and is growing at 50 per cent a year. As ad dollars move away from search, Google has been losing share of the overall online advertising market to Facebook. In the US, eMarketer expects Google"s share of digital ads to fall from 40 per cent(2013), to 38 per cent(2014), to 34 per cent(2016). Facebook"s market share is expected to climb from 8 per cent to 11 per cent in the same period. Part of the problem is that search ads do not seem to be quite as successful on mobile(the fastest-growing part of digital ad spend)as on desktop. People do use search on phones—search is about half of mobile ad spending. But these ads appear to have less impact than targeted social media ads, and could fall off quickly as more effective forms of mobile advertising are found. Face-book, which has a higher ad market share on mobile than on desktop, has seen its click-through rate triple over the past year, according to Nanigans. Unfortunately for Google, mobile advertising is getting increasingly crowded. Snapchat, a popular photo-sharing app, is launching ads. And Yahoo is trying to boost its mobile ad offering with its acquisition of Flurry. The search business naturally tends towards monopoly. But the advertising business, ex-search, does not. What does the word "shrink" mean
