Gulf War Illness significantly reduces white blood cells' ability to make energy

Gulf War Illness (GWI), which affects approximately 250,000 U.S. veterans, has been found to significantly reduce the ability of white blood cells to make energy and creates a measurable biochemical difference in veterans who have the disease. The finding comes from a physician who noticed GWI symptoms paralleled those of mitochondrial diseases. Analysis revealed significantly lower levels of...

What happens when cats get fat? Scientists weigh in

Cat owners want Kitty to be happy, but providing an abundance of food and snacks can have unintended consequences. Feline obesity is on the rise, impacting the health, longevity, and wellbeing of cats. A new study looks at what happens in the digestive system and gut microbiota when cats eat too much.

Heart-brain link offers new potential explanation for fainting

Fainting, a temporary loss of consciousness, affects almost 40% of people, yet scientists and physicians don’t know exactly why it happens. A drop in heart rate, blood pressure, and breathing rate—a trio of symptoms long known as the Bezold-Jarisch reflex—can contribute to fainting, researchers have hypothesized. Now, neuroscientists have pinpointed a nerve pathway between the heart...

Analysts who disclose company forecasts for a wide range of financial outcomes have better performance, finds study

If you are in search of accurate forecasts on a company's earnings and future stock prices, you could do better turning to analysts who have recently disclosed a wide range of forecasts for the same company—not only earnings and price targets, but also cash flow, dividends, book value, capital expenditure, gross margin, operating income, pre-tax income forecasts and so on, according to a new...

Scientists develop a legged small celestial body landing mechanism for landing simulation and experimental test

Landing stably is a precondition for exploring a small celestial body in situ. The surface of a small celestial body frequently has weak gravity and is irregular, and the surface environment is unknown and uncertain. The landing mechanism tends to rebound and turn over, and the landing stability time is long. However, while most landing performance research has focused on lunar landing, there are...

Reactant enrichment of nanoreactors boosts hydrogenation performance

Hollow-structured supported metal catalysts (i.e. nanoreactor catalysts) with encapsulated active sites and well-defined shells provide an ideal place for multicomponents to react or transform cooperatively in an orderly manner, and efficiently have been recognized as one of the most popular catalyst candidates.
