Higher egg and cholesterol consumption hikes heart disease and early death risk

Cancel the cheese omelet. A large, new study of nearly 30,000 people reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of cardiovascular disease and death from any cause. People need to consume lower amounts of cholesterol to have a lower risk of heart disease, the study authors said.


For older adults, sense of control tied to feeling younger

A recent study finds that older adults feel younger when they feel that they have more control over their daily lives, regardless of stress or health concerns. However, stress and health -- not a sense of control -- play a significant role in how old younger adults feel.


With single gene insertion, blind mice regain sight

People left blind by retinal degeneration have one option: electronic eye implants. Neuroscientists have now developed an alternative: gene therapy that, in tests, restored vision in blind mice. A gene for green opsin delivered via virus gave blind mice enough sight to discern patterns on an iPad at a resolution sufficient for humans to read. Given existing AAV eye therapies already approved, this new therapy could be ready for clinical trials in three years.


Having great-grandparents, cousins with Alzheimer's linked to higher risk

Having a parent with Alzheimer's disease has been known to raise a person's risk of developing the disease, but new research suggests that having second- and third-degree relatives who have had Alzheimer's may also increase risk.
