1 . Parents who want their kids to succeed more than anything are now being sold a high-tech solution. Class 120 is $199-a-year smartphone app that tracks teenagers and alerts parents if the kid isn’t in his or her scheduled class.

Is it a good idea for parents to track whether their young adults are in class? In short: No. This is a terrible idea.

One of the fundamental purposes of a college is learning to be an independent person. That means learning how to do what needs to be done, whether one particularly feels like doing it or not.

It’s easy to see why parents are keen on tracking their kids. A student is admitted to college by a process that focuses mainly on grades and scores. Monitoring grades and scores is easy. The parents may think that:

“Our child is succeeding. We are good parents. We are happy.” But grades and scores can’t tell everything.

They don’t take into account whether their kids have the strength of self-discipline (自律) and the skill needed to care for himself or herself.

Monitoring the development of character is much harder for parents. Character growth happens through encountering (遇到) and learning to deal with disappointments and failure. You never know which problem will be the point for growth.

However, letting kids fail can be really difficult for anxious parents. They believe that success means being perfect and never failing. The truth is that kids need to learn to fail.

College is an ideal place to practice adults’ responsibility and independence. Students need to make their own decisions about whether to get out of bed and go to work in the morning.

Maybe your child hasn’t learned this lesson by now, but he or she has to learn it sometime. An alarm clock’s job is to wake you up, but it does not provide a reason.

3 . Police recently caught the suspected Golden State Killer using a tool they could only have dreamed of decades ago, when a shocking series of murders shook California: a database filled with people’s genetic data (基因数据).

Police used an open-source database called GEDmatch to find relatives who matched genetic material taken from an old crime scene, then worked backward to identify and catch 72-year-old former police officer Joseph James DeAngelo.

GEDmatch’s 950, 000 users voluntarily upload and share their genetic information, making it accessible to others who share their own data—including law enforcement (执法). More than a dozen other similar platforms also exist. “If your relatives have contributed and you are part of even a family tree that appears online in one of these shared resources, you can be indirectly tracked through the combination of their DNA and the publicly available family history,” says Dr. Robert Green, a medical geneticist at Harvard Medical School.

Data sent to commercial companies like 23andMe, which has over 5 million customers, is much tougher for outsiders to access, but the case has still highlighted the issue of genetic privacy.

Although many genetic-testing companies have been asked to cooperate with legal investigations (调查), and clearly warn customers of this possibility, not all requests are honored. “23andMe has never given customer information to law-enforcement officials, ” a company representative told TIME.

The risks of keeping such sensitive data private are high. The potential for abuse exists; for example, insurance companies could theoretically use genetic data to refuse coverage (保险项目), Green says. But the systems in place to prevent misuse appear to be working. One is the Genetic Information Nondiscrimination Act, a 2008 law that protects consumers from employment and insurance discrimination related to genetics. As long as that’s the case, Green says, the good of genetic tests outweighs the bad.

Sharon Zehe, a lawyer for the department of laboratory medicine and pathology at the Mayo Clinic, takes a more cautious approach. “Family tree services can be fun, but make sure you are using a reputable organization that has strong privacy policies in place,” she says. “Genetic data is biologically as important as a fingerprint.”
