Where do elbows and knees come from? Biologists track them back to our boneless, sharklike ancestors
Ask an older person where painful arthritis strikes and most will point to their joints—knees, hips, and fingers. That’s because as people age, those joints lose the cartilage and viscous fluid, known as synovial fluid, that keeps them supple. Sharks and skates have no bones—and no arthritis—but they apparently have the same kind of joints we do. Once thought to exist only in bony vertebrates, these so-called
synovial joints actually evolved in the much older ancestor of cartilaginous and bony fish
, researchers reported earlier this month in a preprint on bioRxiv.
“They very convincingly show tha...

Laser technology offers breakthrough in detecting illegal ivory
A new way of quickly distinguishing between illegal elephant ivory and legal mammoth tusk ivory could prove critical to fighting the illegal ivory trade. A laser-based approach developed by scientists at the Universities of Bristol and Lancaster, could be used by customs worldwide to aid in the enforcement of illegal ivory from being traded under the guise of legal ivory. Results from the study are published in PLOS ONE today [24 April]. (Source: University of Bristol news)

How Do You Treat Nasal Fractures?
Discussion
Facial trauma is common and accounts for about 11% of all pediatric emergency room visits. Nasal fractures are fewer in younger ages but increase in incidence as children age because of increased opportunity for trauma (e.g. playing, sports, car accidents, etc.). Anatomy also plays a part as young children have more cartilaginous structures and the nose does not protrude as much as an older child or adult who also have more osseous structures. The nasal structures have 2 bigger growth phases from 2-5 years and also at puberty. Adult size is reached in 16-18 years for females and about 2 years later for males (18...

Is your equipment helping or hurting patient communication?
Brian Bradfield.With existing scheduling backlogs, radiology technologists are feeling the pressure to move fast. While patient volumes have swelled, staffing challenges have left a less-than-optimal workforce with a bigger workload. A critical element of care can suffer on account of this pressure: patient communication.
Effective patient communication is already a topic of concern in radiology. While there's a case for providing more training opportunities to support good patient communication, there's also a conversation to have about how the equipment used by a facility can impact patient communication and, ultimately...
