The American Cancer Society has issued new guidelines for lung cancer screening, expanding the criteria beyond just cigarette smokers. The guidelines now recommend that individuals between the ages of 50-80 with a 20-pack-year history or more should receive a yearly low-dose CT scan to screen for lung cancer. This change is estimated to increase the number of eligible individuals by about 5 million and could prevent an additional 21% of lung cancer deaths compared to the current recommendations. However, insurance coverage for these screenings may vary, so it is important to consult with a primary care provider to determine eligibility and coverage.

Forensic artists have created a digital facial approximation of the "old man" Neanderthal, whose nearly complete skeleton was discovered in France in 1908. Using CT scan data and measurements from a human skull, the artists reconstructed the face shape, skin, and muscles of the Neanderthal. The new reconstruction offers a more accurate and humanized depiction of the ancient man, challenging previous exaggerated ape-like portrayals. This advancement in facial reconstruction provides new insight into the anatomy and physiology of Neanderthals, highlighting their similarities and differences to modern humans.

Forensic artists have created a digital facial approximation of a Neanderthal known as the "old man" based on CT scan data of his skull. The Neanderthal, who lived between 47,000 and 56,000 years ago, had hallmark traits such as an oversize brow ridge and large eye orbits. The facial approximation provides a more accurate and humanized representation compared to previous exaggerated reconstructions. This new perspective reflects evolving knowledge about Neanderthals, showing their similarities to modern humans in anatomy and behavior.

A CT scan of the skull of a Thescelosaurus neglectus dinosaur named Willo has revealed that despite its small brain, it possessed unique sensory traits associated with animals that spend time underground, such as a heightened sense of smell and exceptional balance. The dinosaur had limited hearing abilities but compensated with a well-developed sense of smell. These findings suggest that T. neglectus may have engaged in burrowing behaviors or lived underground, similar to its ancestors. The research provides insight into the sensory abilities and potential lifestyles of dinosaurs, expanding our understanding of their ecological adaptations.

New guidelines from the American Cancer Society recommend that even heavy smokers who quit 15 years ago or more should undergo yearly lung cancer screening with low-dose CT scans. The previous guidance, which excluded ex-smokers who quit more than 15 years ago, was based on a flawed premise that the risk of cancer decreased over time. However, data revealed that the risk of lung cancer actually increased with age, even among those who had quit smoking long ago. Currently, only a fraction of high-risk individuals are getting screened, contributing to the abysmally low rates of screening in the United States. The new guidelines will expand eligibility for screening, potentially saving more lives through early detection of lung cancer.

A French angelfish at the Denver Zoo was experiencing buoyancy issues and swimming abnormally, prompting a CT scan that revealed the cause: enteritis, or inflamed intestines, resulting in increased internal gas. The fish was treated with antibiotics and is now swimming normally. The CT scan, which required special accommodations, was shared on Instagram by the zoo. This comes after a recent case where a 376-pound alligator at a Florida zoo was diagnosed with an ear infection after CT scans and X-rays.
