Dating Your Blood

The CSI franchise makes it seem like detectives only need a few drops of blood, some saliva, or a strand of hair to close a murder investigation within 24 hours. Some of the techniques on the shows do not exist—or if they do, it takes weeks, not minutes, to get results. But many of these fantasies are tools investigators dream of using, and scientists continue to search for new ways to solve crimes using DNA evidence. Researchers at Erasmus MC University Medical Center Rotterdam in the Netherlands were able to determine a person’s age by running a DNA test on a drop of blood.

Investigator Manfred Kayser designed a test that looks for spliced remnants of T cells in the blood. When bacteria or viruses invade a body, the immune system triggers T cells in the blood. As the T cells activate, they produce small, spherical cells called signal joint TCR excision circles (sjTRECs). Researchers know that sjTRECs decrease at a constant rate each year, making easy to quantify age.

Kayser analyzed 200 blood samples from infants to 80-year-olds.

Using florescent DNA, which binds to sjTRECs, Kayser determined the amount of sjTRECs in the blood, estimating a person’s age within nine years. He notes that this test worked just as accurately on samples, which sat in storage for a year, meaning this could be an affective tool in reducing cold case backlogs. This test is one of the most accurate phenotypic DNA tests. The other frequently noted phenotypic test determines whether a person’s eye color is blue or brown, but is far less accurate.

And while guessing an age within nine years may not seem accurate enough, it can be useful to investigators who have no information about suspects.

The First-Ever Troop of Homeless Girl Scouts Just Crushed Their Cookie Sales Goal

Selling 32,500 boxes of cookies in a single week would be noteworthy for any team of Girl Scouts, but it's an especially sweet achievement for Troop 6000: The New York City-based chapter is the first-ever Girl Scout troop composed entirely of children living in homeless shelters.

According to NBC News, this season marked the first time the troop took part in the organization's annual cookie sale tradition. In early April, they received exclusive permission to set up shop inside the Kellogg's Café in Union Square. They kicked off their inaugural stand sale aiming to sell at least 6000 boxes of cookies: At the end of six days, they had sold more than 32,500.

Some customers waited in line an hour to purchase boxes from the history-making young women. Others gave their money directly to the troop, collectively donating over $15,000 to fund trips and activities. After purchasing their cookies, customers could also buy special Girl Scout cookie-inspired menu items from the Kellogg's store, with all proceeds going to Troop 6000.

The troop formed in 2016 as a collaboration between the Girl Scouts of Greater New York, Mayor de Blasio, and the city Department of Homeless Services. Meetings are held in shelters across the city, and many of the troop leaders, often mothers of the scouts, are homeless women themselves. About 40 percent of New York's homeless population are children, and Troop 6000 had to expand last summer to accommodate a flood of new recruits. Today, there are about 300 girls enrolled in the program.
