Lower-than-normal zinc levels may contribute to high blood pressure (hypertension) by altering the way the kidneys handle sodium. The study is published ahead of print in the American Journal of Physiology--Renal Physiology.
By studying the phenomenon of contagious yawning, the researchers learned that people's reactions in virtual reality can be quite different from what they are in actual reality. They found that contagious yawning happens in VR, but people's tendency to suppress yawns when they have company or feel they're being watched don't apply in the VR environment. Further, when people immersed in VR are aware of an actual person in the room, they do stifle their yawns. Actual reality supersedes virtual reality.

In a Journal of Orthopaedic Research study, scientists used 3D printing to repair bone in the joints of mini-pigs, an advance that may help to treat osteoarthritis in humans.
Migraine with aura was associated with an increased risk of ischemic stroke in the Atherosclerosis Risk in Communities study, but a recent post-hoc analysis published in Headache reveals unexpected results suggesting that onset of such migraines before age 50 years is not associated with such risk. Later onset of migraine with aura was linked with a higher risk, however.
In an International Journal of Geriatric Psychiatry study of individuals diagnosed with dementia in the United Kingdom, people from minority ethnic backgrounds (Asian and black patients) had lower cognitive scores and were younger when they were diagnosed with dementia than white patients.
