How high-tech replicas can help save our cultural heritage

A virtual reality project uses 3-D videos to transport elderly survivors of the forced Partition of India and Pakistan to the ancestral homes they haven't seen in over 75 years. Since most survivors are unable to get a visa to return to their original homes, the immersive experience provides an opportunity to intimately experience footage of their villages and hear messages from current residents.

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.

A Nepalese company called Traditional Homes was formed in order to restore traditional Newari homes to prevent them from being demolished. The houses are by the indigenous Newar people of the Kathmandu Valley and boast beautiful latticed windows and courtyards. These small restoration projects have taken off thanks to websites like TripAdvisor and Booking.com. Not only does the money go directly to the locals supporting the new bed-and-breakfasts, but tourists also receive an authentic and homey experience.

In 1890, an anthropologist used an early audio recording device called a phonograph to record three spokesmen for the Passamaquoddy tribe singing songs, telling stories, and pronouncing simple words. After years of efforts to eradicate Native American culture and language, these recordings were found again and shared with modern-day members of the Passamaquoddy tribe, who now use it to transcribe, interpret, and add to their cultural knowledge. The songs and stories have already begun making their way back into tribal events.

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.

An online German museum is collecting and creating access to the sounds of obsolete technology such as portable cassette players, modems, and rotary phones. Through this collection, the museum preserves a tangible physical history that would be otherwise lost.

Untold RVA, a project developed by ‘tactical urbanist’ Free Egunfemi, intervenes in public space to foreground the history of slavery and the lives of the enslaved in Richmond. While work is being done to dismantle Richmond’s commemorations of the Confederacy, Egunfemi and other activists are working to ensure the people survived unimaginably oppression are not forgotten.

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.

In the face of terror and war, art and history needed protection. A group of professors, activists, archeologists, and historians created a network to preserve and protect art and history in Syria.
