Non-native plants and animals expanding ranges 100-times faster than native species, finds new research
An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are mo.....»»
Ultrasound beam triggers "nanodroplets" to deliver drugs at exactly the right spot
Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those where it isn't needed—or.....»»
