[Shop Now for $25.99]( Adding to the already huge pile of Boeing’s woes, a new whistleblower has alleged that the airliner lost tracks of damaged parts or those that were not up to the specification, and these “parts are likely being installed on airplanes.” The allegations were released right ahead of Boeing CEO Dave Calhoun’s hearing before the Senate panel on Tuesday. Calhoun is scheduled to face questions from the Senate Permanent Subcommittee on Investigations.

Mohawk has stated that Boeing [tried to hide the parts]( that were not up to the mark from the Federal Aviation Administration (FAA) by falsifying records, according to a report by CNN. As per the report, the whistleblower goes on to mention that the company likely ended up [losing trac](k of the nonconforming parts, and they were installed in some planes. According to another report by CNBC, the parts on which questions have been raised were in Boeing’s Renton plant in Washington. The plant makes the company’s famed 737 Max plane. 🦕 Fossil reveals 246-million-year-old reptile that dominated super-ocean A 246 million-year-old fossil of a [polar sea reptile]( has been discovered on New Zealand’s South Island. An international team of researchers led by Uppsala University studied the fossilized bone, which was recovered from a streambed at the foot of Mount Harper on the South Island of [New Zealand](. The extinct creature belonged to the genus [Nothosaur](. Interestingly, this is identified as the [oldest sea-going reptile](, some 40 million years older than anything previously discovered in the Southern Hemisphere. 🧠AI helps detect Parkinson’s with 100% accuracy 7 years before symptoms Researchers from UCL and University Medical Center Goettingen have developed a [blood test]( that utilizes artificial intelligence ([AI]() to [predict Parkinson’s disease]( up to seven years before symptoms show up. Parkinson’s disease, a neurodegenerative disorder characterized by tremors, stiffness, and slowness of movement, is the f[astest-growing neurological condition globally](. Diagnosing it early has been a challenge, but a new study brings promising news. “As new therapies become available,” says Professor Kevin Mills, a senior author of the study, “we need to diagnose patients [before they develop symptoms](. We cannot regrow brain cells, so protecting existing ones is crucial.” Love what you're reading, but too many emails?
