Now, for the very first time, it has also been scientifically proven that this principle of bicycle stability can also be used to maintai

:: Does metal use slow when a country's wealth grows? Maybe not, study showsIt is widely believed that a nation's metal use plateaus when that country's gross domestic product (GDP) reaches a threshold of $15,000 per person; with rising affluence, the theory goes, nations achieve a new level of resource efficiency.
:: Does metal use slow when a country's wealth grows? Maybe notIn a new study, a Yale-led team of researchers found that GDP remains intrinsically linked with metal use even as affluence grows — a relationship that might threaten long-term global access to critical metals and hopes for a low-carbon future.

:: Does physical activity influence the health of future offspring?Physical and mental exercise is not only beneficial for your own brain, but can also affect the learning ability of future offspring — at least in mice. Researchers from the German Center for Neurodegenerative Diseases (DZNE) report these findings in the journal Cell Reports.

:: Does physical activity influence the health of future offspring?Physical and mental exercise can affect the learning ability of future offspring, at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate in both the brain and germ cells following physical and mental activity. Prof. André Fischer and colleagues from the German Center for Neurodegenerative Diseases (DZNE) i

:: Dog breath and stinky studies: Do pets need to be knocked out for dental care?Most professional veterinary organizations recommend anesthesia to ensure thorough dental care for pet dogs and cats. Despite this, some companies are trying to mislead the pet-owning public by claiming they have high quality evidence showing they provide the same benefit without the risks. Their research smells worse than old chihuahua breath.
