Researchers from University of Southern Denmark analyze fragments of a tibia, femur, and mummified foot attributed to the apostles, finding the femur dates back to AD 214-340, not St. James' time, casting doubt on their authenticity. The study sheds light on early Christian traditions and practices surrounding relic movements.
Researchers at Vanderbilt University found that wearable sensors measure the wrong thing, focusing on foot impact rather than muscle contraction forces. They discovered a strong correlation between ground reaction forces and tibial bone loading was false, and only combined data from multiple sensors can estimate bone stress accurately.
Researchers found an association between lead levels in the shin bone and treatment-resistant high blood pressure in men. The study suggests that cumulative lead burden may be an overlooked risk factor for drug-resistant hypertension.
Researchers found that smoking significantly delays bone healing and increases risk of nonunion among women aged 30-49. The study analyzed patient records over 20 years and revealed a significant delay in bone healing among smokers, with implications for treatment and prevention strategies.
A researcher re-examined seven bone measurements from 1940 and found they were more similar to Amelia Earhart than 99% of individuals in a large reference sample. The study concluded that the bones belonged to Earhart, citing evidence including her humerus and radius lengths.
A recent study reveals prehistoric women performed intensive manual labor for thousands of years, surpassing modern female athletes. This finding highlights the crucial role of women's labor in agriculture's development and underscores the importance of using female comparative data to interpret past behavior.
Scientists have discovered fossilized damselflies in Burmese amber that display ancient courtship behaviors, including elaborate leg structures and wing-like features. The findings suggest that damselfly mating rituals may have occurred as far back as the dinosaur era.
A large international study led by McMaster University researchers found that low-intensity ultrasound treatment after surgical repair of a bone fracture has no effect on recovery time or quality of life. The study involved 501 patients and showed that using either an active or placebo device did not improve outcomes.
A study found that insect tibias are best suited for high-stress activities like jumping and righting when overturned, with similar strength across desert locust, American cockroach, and Death's Head cockroach species.
A frozen mammoth carcass with signs of weapon-inflicted injuries suggests human occupation of the Eurasian Arctic at 45,000 years ago. This finding challenges previous estimates and highlights advancements in mammoth hunting that enabled human survival and spread across northernmost Arctic Siberia.
A team of international scientists has dated a species of extinct monkey found in the Dominican Republic to over 1 million years old. The discovery sheds light on primate evolution in the region and provides evidence for the long-term survival of endemic native monkey species.
A team of scientists, including a GVSU professor and alumni, discovered a 1-million-year-old monkey fossil in the Dominican Republic. The species, Antillothrix bernensis, was found to be morphologically consistent with previously collected material but dated to 1.3 million years ago.
A study at Loyola University Medical Center found that knee replacements can treat degeneration caused by Blount disease, resulting in stable knees and no pain medications. Researchers used a scoring system to evaluate the success of the surgery, with mean scores indicating excellent range of motion and low disability.
A new study found that administering antibiotics within the first hour of injury can significantly reduce infection rates in trauma patients. The study, published in the Journal of Orthopaedic Trauma, included 137 patients with open fractures and found that those who received antibiotics early had much lower infection rates.
Research suggests that humans became less mobile and physically active after the transition to agriculture in Central Europe around 5300 BC. Male bones show a decline in strength and rigidity, indicating reduced mobility and heavy physical work, while female bones exhibit more inconsistent trends.
Researchers at Cambridge University have finally resolved the debate on how fleas jump, discovering that they push off with their toes. The team used high-speed cameras and mathematical modeling to analyze flea jumps, finding that both the tarsus and trochanter were involved in the jumping process.
After 15 years, 82 of 90 patients with ACL knee reconstruction still exhibit stable knees and minimal osteoarthritis. Eighty-four percent of males continue at a high level of activity, participating in strenuous sports like soccer and basketball.
