How do you know when it's time for an older adult with mild dementia to stop driving? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. It can impact a person's ability to drive safely. Although all people with dementia will have to stop driving eventually, each case can be unique based on the individual. According to a new study published in the Journal of the American Geriatrics Society, we still need to explore mental or physical tests that can best predict when people with dementia should stop driving.

Highly caffeinated energy drinks (EDs) have been of concern to the public-health community for almost a decade. Many young people consume EDs with alcohol to decrease alcohol’s sedative effects and stay awake longer, enabling them to drink more alcohol. Adding to the growing body of research linking ED consumption with risk-taking and alcohol-related problems, this study examined its relationship with drunk driving. Importantly, the researchers differentiated between the different ways in which EDs are consumed: exclusively with alcohol, exclusively without alcohol, or both with and without alcohol depending on the occasion.

The global aviation industry has pledged that by 2050, it will reduce its net carbon emissions to half its 2005 levels. Achieving this will require not only improved engine efficiency and aerodynamics, but also a turn to renewable jet fuel. The transition has begun, but biofuel makers need more funds and policy support to ramp up production, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Beginning in 2008, Volkswagen installed software to circumvent emissions testing by turning off the nitrogen oxides (NOx) emissions control system in real-world driving in nearly half a million cars. A new analysis using a tool developed and used by the U.S. Environmental Protection Agency to assess the health and economic impacts related to air quality calculates that a single year of elevated emissions from the affected VW vehicles could lead to as many as 50 premature deaths, 3,000 lost workdays, and $423 million in economic costs.
