Cases of missing trans people are rarely solved. A married pair of forensic genealogists is hoping to change that

Genetic genealogy's use in criminal cases has gone mainstream. As the cases of three murder victims in Indiana illustrate, the science of DNA evidence combined with genealogical research and detective work is rapidly ramping up, from a hobby to a curiosity and now to a major commercial and criminal-justice opportunity. Hundreds of missing persons have been identified from decades-old remains, or murder suspects identified from old biological evidence in cold cases. By creating a family tree of the victim or suspect, investigators can zero in on an identity more quickly and inexpensively than ever.

Oregon law enforcement agencies partnered with a Virginia laboratory, Parabon NanoLabs, to use genetic genealogy to learn the identities of people whose remains were found long ago but never identified. To give peace of mind to families who never knew for sure of their loved ones' deaths, researchers use DNA samples taken from the human remains to compare to publicly available DNA profiles shared by people using home DNA tests. This can identify a victim's family tree. So far, Parabon has identified six of the 10 people it has tested for Oregon. The state has more than 150 unidentified skeletal remains.

In 1965 a traveling salesman published a series of travel guides with gay or gay-friendly businesses across the U.S. that became survival guides for the LGBTQ community. “Mapping the Gay Guides” has digitized those collections, allowing users to explore the original descriptions and added historical content written by graduate students. Reasons for why locations appear and disappear from year-to-year are provided, which sometimes intersect with LGBTQ hate crimes. A $350,000 grant from the National Endowment for the Humanities will allow them to continue to preserve and make the forgotten history accessible.

As a way to combat unemployment due to the COVID-19 pandemic and to prevent further deforestation in Kenya, local rangers are using smartphones, satellite feeds, and global mapping to monitor their forests. The project employs more than 250 people and allows them to target vulnerable areas more effectively. Because of their efforts, there have been lower incidences of illegal logging and forest fires from poachers.

The use of genetic genealogy technology has given law enforcement the opportunity to compare DNA that people have tested personally through companies like 23andMe to DNA collected at crime scenes. Recently being used to help free people from prison who have been wrongfully convicted, the technology gives law enforcement insight as to the family tree the DNA is connected to. While showing potential, it has also raised concerns around genetic data privacy, with many companies now requiring permission from users.

Patrick Ball, cofounder of the nonprofit Human Rights Data Analysis Group (HRDAG), has helped use quantitative data to put numbers behind things that were before unprovable — i.e. the difference between genocide and random violence. Ball and HRDAG have analyzed existing data to come up with the "invisible" data, overlaying several sets of statistics with machine learning to come up with stats like the fact that you were eight times more likely to be killed by the army in the Ixil region in the early 1980s if you were indigenous. Ball also advises nine truth commissions, four UN commissions, and more.

GEDmatch started as a "casual side project," but investigators have been using the genealogy website to solve murder and sexual assault cases, opening a new set of both opportunity and ethical questions. The site is free to all, so investigators have used it to match DNA information and find suspects using family connections - a strategy that concerned the founders of the site at first, although they've come around to the idea after seeing the positive impact it has had.

The National Park Service has resorted to microchipping hundreds of saguaro. Despite extensive legal protections, the iconic cacti are going missing. Rangers can only read the microchip by scanning a suspect cactus, but they hope this move will serve as an additional deterrent to would-be thieves hoping to cash in on the demand for saguaro among building owners.

Some German cities have created voucher programs that subsidize the cost of taking a taxi for women who feel unsafe walking or using public transit at night. In Cologne, 1,500 vouchers were used within days of their release, and Munich has more than tripled the number of vouchers it provides due to demand.

The Everywhere Is Queer mobile app houses a directory of over 13,000 LGBTQ+-owned brick-and-mortar and online businesses, services and community groups around the world. The app features a map that highlights LGBTQ+-friendly businesses and safe spaces for members of the community and allies to frequent. The app also features a job board and access to therapists and has been downloaded over 80,0000 times since February.
