DNA analysis and a digital facial reconstruction of a 3,500-year-old Mycenaean burial reveal the woman buried beside a man with three swords was his sister, not his wife. The reconstruction shows a young woman; bone and artifact evidence suggest she wielded or owned weapons and endured labor, prompting a rethink of gender roles in Late Bronze Age Mycenae.
At the 100-day mark in Nancy Guthrie’s disappearance, investigators say the case could hinge on a strand of DNA being analyzed by the FBI at Quantico; the DNA was recovered from Guthrie’s Tucson home and initially tested at a private Florida lab before being sent to Quantico, with experts stressing that forensic DNA work— including potential family-tree analyses—takes time. A prior DNA lead from gloves yielded a dead end confirming no connection to the case. Authorities continue pursuing doorbell footage, tips, and digital data, while rewards totaling over $1 million are offered for information leading to Guthrie’s recovery or the arrest of those involved.
South African authorities euthanised a large crocodile and retrieved a Portuguese businessman’s remains from its stomach, confirming the victim as Gabriel Batista, 59, who disappeared after his vehicle was swept away while crossing a partially submerged bridge over the Komati River. The crocodile, about 600 kg and five metres long, was airlifted for examination and its stomach also contained several clothing items; identity was confirmed by DNA analysis as the investigation continues.
Louisiana police arrested four men in the 1982 murder of Roxanne Sharp, aided by new DNA testing and a revived investigation sparked by a podcast; the case, long tracked by former Covington officer Herbie Joiner who died before arrests, underscores persistent collaboration and technological advances in solving cold cases.
Researchers analyzing dust and fibers from the Turin Shroud identified plant DNA—carrot, bread wheat, maize, peanuts, and various fruits—suggesting contamination over time rather than revealing the cloth’s age; metagenomic DNA cannot confirm origin, while radiocarbon dating in 1988 placed the cloth at 1260–1390 AD and a 2024 analysis hinted at a date closer to 2,000 years, with the final results not yet published.
Researchers analyzing dust and fibers from the Shroud of Turin report plant DNA—carrot, bread wheat and other crops—signalling contamination over time rather than confirming the relic’s age; they caution metagenomics can’t reliably date the cloth, even as radiocarbon dating in 1988 placed it medieval (1260–1390 AD) and 2024 WAXS results broadly align with a two-millennium history.
DNA analysis of the Beachy Head Woman, a Roman-era skeleton found near Beachy Head, shows she was likely local to the Roman Britain population, revising earlier guesses of Sub-Saharan African or Mediterranean ancestry; improved DNA techniques also updated her facial reconstruction to reflect light skin, blue eyes, and fair hair, placing her life along the Roman coastal landscape (129–311 AD) and underscoring how genetics can revise archaeological narratives.
DNA testing identified the remains found in a car in the Columbia River as Kenneth, Barbara, and Barbie Martin, the Oregon family missing since 1958. Authorities said there was no evidence of foul play and closed the case, with the car having been recovered from the river years after their disappearance.
DNA analysis confirmed the remains in a car submerged in the Columbia River are Kenneth Martin, Barbara Martin, and their daughter Barbie, the Oregon family who vanished in December 1958; authorities found no evidence of foul play. The Ford wagon was located in 2024 and recovered in following years, with Othram handling the forensic work, and two of the family’s children had been found years earlier while the other members never turned up.
DNA analysis identified the remains found in a car wreck in the Columbia River as Kenneth, Barbara, and Barbie Martin, solving the Oregon family’s 1958 disappearance. Two of the children had been found earlier; the car was recovered after sediment encasement made retrieval partial. Investigators found no evidence of foul play after the identification.
Artemis II completes its lunar flyby with a record-setting Pacific splashdown, while New Zealand’s kakapo marks a major breeding season as part of its recovery effort. In archaeology/ancient DNA news, the Shroud of Turin DNA analysis reveals human and non-human DNA (including carrots and red coral), fueling ongoing debate about its origin. The week also highlights progress toward a functional cure for type 1 diabetes in a Science Spotlight.
Repair workers uncover skeletal remains beneath an altar in Maastricht’s church during tile repairs; early indicators—a French coin and a chest wound—point to Charles de Batz de Castelmore, Count d’Artagnan, the real-life inspiration for The Three Musketeers, with DNA testing underway to confirm the identity.
DNA from a black glove found near Nancy Guthrie's Arizona home has been traced to a local restaurant worker and is not connected to the investigation; the FBI database did not yield a match, though other DNA analysis is underway at a private Florida lab, and investigators collected about 16 gloves total (mostly from searchers) as they continue to pursue leads.
Genetic and isotopic data from the Beachy Head Woman, a 2,000-year-old skeleton, show she grew up locally in southern Britain during Roman Britain, contradicting earlier skull-based theories of African or eastern Mediterranean ancestry and highlighting the value of multi-method approaches over cranial traits alone.
Recent analysis of fossils housed in Alaska's University of Alaska Museum revealed that what were thought to be mammoth bones from the Ice Age are actually from two ancient whales, a discovery confirmed through isotope and DNA analysis, challenging previous assumptions about the fossils' origins and highlighting the importance of modern scientific techniques.
