However, some individuals with very mild dementia can continue to drive safely for extended periods.
Field mice have sacrificed immunity protection to develop faster fertilization, resulting in instability of the sperm's acrosome. This process may provide insight into human infertility, as humans lack this rapid reaction.
A study found that individuals with fewer years of education are more likely to have a delayed realization of cognitive problems that could be Alzheimer's disease. Patients with lower education levels were also more severely impaired on their first visit, suggesting they may only seek medical attention after symptoms become unbearable.
A Penn State study found that male teenage football players and wrestlers are more likely to get into serious fights compared to non-athletes. The study suggests that the aggressive behavior encouraged by team sports contributes to violence among male peers.
Children as young as 4 years old can use explanation to help them learn and apply what they've learned to other tasks. Listening to an adult's response without providing answers helps children develop critical thinking skills.
Researchers have discovered that cigarette smoke depletes the Sirtuin (SIRT1) gene, which protects against premature aging and inflammation. Testing antioxidant resveratrol may help restore this gene to prevent lung damage and diseases like COPD and lung cancer.
A study by Brown University and Harvard Medical School found that health insurance co-payments significantly reduce mammography use among women. The researchers analyzed data from Medicare managed-care plans and found a 8-11% decrease in breast cancer screening rates among women with co-payments, compared to those with full coverage.
A study by LSU and Yale researchers found that farming practices are responsible for the majority of increased water and carbon in the Mississippi River. The research team analyzed data on precipitation and water export to demonstrate the effects of excess water on river chemistry.
Researchers at Queen's University discovered a genetic link between the nervous system and obesity, shedding new light on the condition's causes. The study found that deleting a specific nerve receptor in worms leads to increased fat accumulation and altered behavior.
A University of Missouri study found that cross-owned television stations produce more local programming news content, with an average of 4-8% more coverage than non-cross-owned stations. Cross ownership also leads to 25% more coverage of local and state politics.
