Cincinnati doctor gets 15 years for lying after DNA solves 1989 rape

Frederick Tanzer, a former Cincinnati physician, was sentenced to 15 years in prison for lying to federal agents after DNA evidence identified him as the perpetrator of a 1989 rape. Although investigators confirmed his guilt through a discarded coffee cup, prosecutors could not charge him for the assault due to expired state statutes of limitations. The case highlights the legal barriers survivors face when time limits bar prosecution, even when modern forensic technology solves decades-old crimes. Tanzer pleaded guilty to false statements after being tricked into denying the attack, while the victim, Dana Beatty, continues to advocate for eliminating such time limits.

DNA Proof Emerges: Jefferson Fathered Hemings Children, Smithsonian Study Finds

DNA Proof Emerges: Jefferson Fathered Hemings Children, Smithsonian Study Finds

A Smithsonian-led team sequenced a lock of Thomas Jefferson's hair and, by comparing its genome to living descendants of Sally Hemings, concludes there is strong evidence Jefferson fathered Hemings's children Madison and Eston. The 15-year project used advanced ancient-DNA sequencing and 20,000 simulations to test paternity. The findings, which align with longstanding speculation, also note a Hemings descendant briefly withdrew from participation; researchers say these techniques have since helped solve cases like the Gilgo Beach murders and the Golden State Killer.

Colorado DNA-Data Analyst Sentenced for Wide-Scale Forensic Manipulation

Colorado DNA-Data Analyst Sentenced for Wide-Scale Forensic Manipulation

Former Colorado Bureau of Investigation forensic analyst Yvonne Woods pleaded guilty to perjury, attempting to influence a public servant, forgery and cybercrime for manipulating DNA data in hundreds of cases. She was sentenced to 10 years in prison, with dozens of other counts dismissed as part of a plea. The misconduct prompted prosecutors to review hundreds of cases, led to at least one murder conviction being vacated, and spurred reforms at the state lab. Officials say concerns about Woods’ work date back to 2014, with the investigation beginning in 2023 and potential retrials in affected homicide cases; the broader response could cost more than $11 million.

Ex-Colorado forensic analyst jailed 10 years for DNA data manipulation

A former Colorado Bureau of Investigation DNA analyst, Yvonne Woods, was sentenced to 10 years after pleading guilty to perjury, attempting to influence a public servant, forgery and cybercrime for manipulating DNA data; her misconduct prompted reviews of hundreds of cases, led to at least one overturned murder conviction, and cost state officials more than $11 million.

Your DNA helps shape personality, but life writes most of the score

A massive study of genetic and personality data from more than a million people finds that DNA accounts for up to about 13% of differences in personality. Thousands of genetic variants each have tiny effects on the Big Five traits (extraversion, openness, conscientiousness, agreeableness, neuroticism). The results show personality is shaped by many genes interacting with environment rather than a single gene, and even link genetic profiles to real-world behaviors like where people live and their COVID-era activity, while non-genetic factors still play a large role.

Bacteria Use Protein as Template to Make DNA Without RNA

Bacteria Use Protein as Template to Make DNA Without RNA

Scientists studying E. coli’s defense system DRT3 found that the enzyme DRT3b can synthesize a repeating C-A-C-A DNA strand using amino acids in the enzyme as a template, effectively translating protein sequence into DNA without an RNA template, while DRT3a still makes DNA from RNA. The two strands form a double helix and together act as an antiviral defense, with RecBCD normally destroying such DNA; when RecBCD is disabled by viruses, accumulating DRT3 DNA halts bacterial growth to stop the virus. The finding, supported by cryo-EM structures and mutational tests, suggests this amino-acid–templating mechanism may be more widespread in nature.

Belgian Prince Laurent Names Former Car Salesman as Secret Son, Grants Inheritance Rights

Belgium’s Prince Laurent has legally recognized Clement Vandenkerckhove, a 26-year-old former Opel car salesman, as his secret son, giving him equal inheritance rights to Laurent’s private estate alongside his half-siblings but without any royal duties, throne rights, or a royal allowance; the revelation followed a TV documentary and echoes past Belgian royal paternity cases.

Bio-Hybrid DNA Memristor Promises Ultra-Low-Power Data Storage

Penn State researchers combined synthetic, silver-doped DNA with perovskite to create a bio-hybrid memristor that stores data with far less energy—about 100 times lower power—while achieving higher storage density than traditional memory, a breakthrough poised to enable neuromorphic, brain-like computing. The device operates at voltages below 0.1 V and remains stable under high temperatures and for weeks at room temperature, highlighting a viable path for low-power, high-density memory in future electronics.

AI designs 16 novel viruses from DNA patterns learned across trillions of nucleotides

Researchers trained Evo, a genomic AI, on more than 9 trillion nucleotide sequences to learn DNA design rules, then used it to generate about 285 candidate viral genomes; 16 of these synthesized genomes assembled into viable bacteriophages that can infect and reproduce in E. coli, demonstrating AI’s potential to design new organisms while highlighting serious biosafety and governance concerns about applying such methods to pathogens.
