Tim Sparks slides a small leather-bound notebook out of an envelope. The book’s yellowing pages contain beekeeping notes made between 1941 and 1969 by the late Walter Coates of Kilworth, Leicestershire. He adds it to his growing pile of local journals, birdwatchers’ lists and gardening diaries. "We’re uncovering about one major new record each month," he says, "I still get surprised." Around two centuries before Coates, Robert Marsham, a landowner from Norfolk in east of England, began recording the life cycles of plants and animals on his estate. Successive Marshams continued recording these notes for 211 years.

Today, such records are being put to uses that their authors couldn’t possibly have expected. These data sets, and others like them, are proving valuable to ecologists interested in the timing of biological events, or phonology. By combining the records with climate data, researchers can reveal how, for example, changes in temperature affect the arrival of spring, allowing ecologists to make improved predictions about the impact of climate change.

But not all professionals are happy to use amateur data. "A lot of scientists won’t touch them, they say they’re too full of problems," says Root. Because different observers can have different ideas of what forms, for example, an open snowdrop. "The biggest concern with ad hoc (临时的) observations is how carefully and systematically they were taken,” says Mark Schwarts of the University of Wisconsin, Milwaukee, who studies the interactions between plants and climate. "We need to know pretty precisely what a person’s been observing—if they just say ‘I noted when the leaves came out’, it might not be that useful.” Measuring the onset of autumn can be particularly problematic because deciding when leaves change color is a more subjective process than noting when they appear.

Overall, most phrenologists arc positive about the contribution that amateurs can make. "They get the raw power of science: careful observation of the natural world," says Sagarin. Others suggest that the right statistics can iron out some of the problems with amateur data. Together with colleagues at Wageoingen University in the Netherlands, environmental scientist Arnold van Vliet is developing statistical techniques to account for the uncertainty in amateur phonological data. Besides, the data are cheap to collect, and can provide breadth in space, time and range of species," It’s very difficult to collect data on a large geographical scale without enlisting an army of observers, says Root.

Phonology also helps to drive home messages about climate change. “Because the public understand these records, they accept them,” says Sparks. It can also illustrate potentially unpleasant consequences, he adds, such as the finding that more rat infestations are reported to local councils in warmer years. And getting people involved is great for public relations. "People are excited to think that the data they have been collecting as a hobby can be used for something scientific—it empowers them” says Root.

Tens of thousands of smartphone applications are running ads from the overwhelming(势不可挡的) advertising networks that change smartphone settings and copy people’s contact information without permission.

Aggressive ad networks can disguise（假扮） ads as text message notifications (通告), and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network’s servers--- information that the ad network can then sell to marketers.

Sounds scary? It’s not a giant problem yet, but it’s a growing one. As many as 5% of free mobile apps use an “aggressive” ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing invasive techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads.

The most popular type of apps that use aggressive ad networks are “Personalisation” apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue(凶猛的) ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn’t easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems.

When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don’t usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints.
