A new study examines how much of the nation's population lives within a certain distance of each county's center, revealing that areas in the South and West are making inroads. The leading edge of top-tier accessibility has inched southward from the Midwest and Northeast to include significant portions of North Carolina and Tennessee.
A new study reveals that modern humans originated from a small ancestral population in sub-Saharan Africa, with genetic splits occurring between hunter-gatherer populations and African farming people around 70,000-140,000 years ago. This finding supports the 'out-of-Africa' theory and provides insights into human migration patterns.
The world's population is aging rapidly, with a quarter of the US population expected to be over 65 by 2030. Various models of care are discussed, including those in the UK, USA, Germany, and Italy. Governments must take initiative to configure or restructure long-term care, examining social and ethical values and public policies on el...

The study suggests that these disease-causing mutations were present in the ancestors of Ashkenazi Jews and were passed down through generations.
A study by American College of Emergency Physicians found that only half of emergency department visits are paid, with payments decreasing from 60.3% to 53% between 1996 and 1998. The decline threatens the ability of emergency departments to provide care to all patients regardless of ability to pay.
