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.”

Life affects friendships. As we grow, marry, fight in wars, move across the country or change jobs, old friendships fall away and new ones form. As long as we live, the things around us change, and as long as things change, friendships are affected.

The London Underground (The Tube)
The main source of public transport in London revolves around the Underground (or the Tube as it is known to Londoners). This network of 12 lines can get you to most places in the center of the city quickly.
It’s almost necessary to get an Oyster Card or a Travelcard. Single tickets are priced starting at the intentionally absurd price of £4.80 (Zone1-3), if you pay cash. Using an Oyster Card, a single fare is £2.30 if you are traveling within the central Zone 1.
On hot days it is also advisable to take a bottle of water with you as Underground trains are not air-conditioned.
Last trains leave central London at around 00:30 weekdays, 23:30 Sundays. First trains leave the suburbs at around 5:00.
The Bus System
Outside the center of London, Tube Stations are farther apart, so buses help fill the gaps. Also, the bus offers a cheaper alternative, even if it is a slower journey.
Cash fares for London buses have been abolished — you cannot pay cash. A bus fare costs £1.50 if people only use buses, and the fare is capped at £4.40 per day for Oyster or contactless card users.
Light Rail and Trains
You can think of the Docklands Light Railway (DLR) and the Tramlink as extensions of the Underground, Travelcards purchased at Tube Stations in East London. The DLR connects with a number of the other train services (including connections at Tower Hill or Bank Stations) and can be used to reach Greenwich, Canary Wharf, and Stratford.
River Services
There are a number of different routes along the River Thames. The faster commuter services operate all day from Greenwich Pier to Embankment and from Putney and Chelsea harbour to Blackfriars during Peak Hours only. These routes will pass a number of places of interest including the Houses of Parliament and London Bridge. A return fare from Putney to Blackfriars will cost about 12 pounds.
National Rail
Once you leave Central London or if you are traveling South of the River Thames, the best public transport option will often be National Rail. There are numerous connections to the Rail System from the Tube. Travelcards can be used for travel on the National Rail (but not the Heathrow Express). Oyster cards can be used up to Zone 6 except certain services including Heathrow Express, Heathrow Connect and HS1.

A funny thing happened to Arthur when he was on the way to work one day. As he walked along Park Avenue near the First National Bank, he heard the sound of someone trying to start a car. He tried again and again but couldn’t get the car moving. Arthur turned and looked inside at the face of a young man who looked worried. Arthur stopped and asked, “It looks like you’ve got a problem,” Arthur said.
I’m afraid so. I’m in a big hurry and I can’t start my car.”
“Is there something I can do to help?” Arthur asked. The young man looked at the two suitcases in the back seat and then said, “Thanks. If you’re sure it wouldn’t be too much trouble, you could help me get these suitcases into a taxi.”
“No trouble at all. I’d be glad to help.”
The young man got out and took one of the suitcases from the back seat. After placing it on the ground, he turned to get the other one. Just as Arthur picked up the first suitcase and started walking, he heard the long loud noise of an alarm.
It was from the bank. There had been a robbery!
Park Avenue had been quiet a moment before. Now the air was filled with the sound of the alarm and the shouts of people running from all directions. Cars stopped and the passengers joined the crowd in front of the bank. People asked each other, “What happened?” But everyone had a different answer.
Arthur, still carrying the suitcase, turned to look at the bank and walked right into the young woman in front of him.
She looked at the suitcase and then at him. Arthur was surprised. “Why is she looking at me like that?” He thought. “The suitcase! She thinks I’m the bank thief!”
Arthur looked around at the crowd of people. He became frightened, and without another thought, he started to run.
Para 1:
As he was running, Arthur heard the young man shouting behind, “Stop, stop!”
