Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to adverse respiratory effects and devastation due to global warming.

A University of Central Florida researcher and his team have developed an advanced new rocket-propulsion system once thought to be impossible.

The system, known as a rotating detonation rocket engine, will allow upper stage rockets for space missions to become lighter, travel farther, and burn more cleanly.

The result were published this month in the journal Combustion and Flame. “The study presents, for the first time, experimental evidence of a safe and functioning hydrogen and oxygen propellant detonation in a rotating detonation rocket engine,” said Kareem Ahmed, an assistant professor in UCF’s Department of Mechanical and Aerospace Engineering who led the research.

The rotating detonations are continuous, Mach 5 expl...

Study shows low intake of flavonoid-rich foods linked with higher Alzheimer’s risk over 20 years. Older adults who consumed small amounts of flavonoid-rich foods, such as berries, apples and tea, were two to four times more likely to develop Alzheimer’s disease and related dementias over 20 years compared with people whose intake was higher, according to a new study led by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.

The epidemiological study of 2,800 people aged 50 and older examined the long-term relationship between eating foods containing flavonoids and risk of Alzheimer’s disease (AD) and Alzheimer’s disease and related dementias (ADRD)...
