He Was Expected To Get Alzheimer's 25 Years Ago. Why Hasn't He?

2 months 3 weeks ago
Doug Whitney carries a genetic mutation that guaranteed he would develop Alzheimer's disease in his late forties or early fifties. His mother and nine of her thirteen siblings died from the disease. His oldest brother died at 45. The mutation has decimated his family for generations. Whitney is now 76 and remains cognitively healthy. The New York Times has a fascinating long read on Whitney and things happening around him. Scientists at Washington University School of Medicine in St. Louis have studied Whitney for 14 years. They extract his cerebrospinal fluid and conduct brain scans during his periodic visits from Washington State. His brain contains heavy amyloid deposits but almost no tau tangles in regions associated with dementia. Tau accumulation correlates directly with cognitive decline. Whitney accumulated tau only in his left occipital lobe, an area that does not play a major role in Alzheimer's. Researchers identified several possibly protective factors in Whitney's biology. His immune system produces a lower inflammatory response than other mutation carriers. He has unusually high levels of heat shock proteins, which prevent proteins from misfolding. Scientists believe his decade working in Navy engine rooms at temperatures reaching 110 degrees may have driven this accumulation. He also carries three gene variants his afflicted relatives lack. His son Brian inherited the mutation and remains asymptomatic at 43. Brian received anti-amyloid drugs in clinical trials. Researchers published their findings on Whitney in Nature Medicine. They described the study as a call for other scientists to help solve the case.

Windows Product Activation Creator Reveals Truth Behind XP's Most Notorious Product Key

2 months 3 weeks ago
Dave W. Plummer, the Microsoft developer who created Task Manager and helped build Windows Product Activation, has revealed the origins of Windows XP's most notorious product key. The alphanumeric string FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 was not cracked through clever hacking but leaked as a legitimate volume licensing key five weeks before XP's October 2001 release. A warez group distributed the key alongside special corporate installation media. Windows Product Activation generated hardware IDs from system components and sent them to Microsoft for validation. The leaked volume licensing key bypassed this entirely. The system recognized it as corporate licensing and skipped phone-home activation. Users could install XP without activation prompts or 30-day timers. Microsoft later blacklisted the key.
