Environmental molds can cause lung infections in people with vulnerable immune systems. Some molds have developed drug resistance from agricultural exposures, which makes fungal infections more difficult to treat. Researchers from Imperial College…

Saturn’s largest moon, Titan, is surprisingly similar to Earth in landscape formations, according to new models produced by planetary scientists. Seen from space, the moon, larger than the planet Mercury, has other similarities to Earth – including rain-filled rivers, lakes and seas – although on Titan rain is liquid methane , falling through nitrogen winds….

In the animal world, there are examples of creatures that use extremely fast speeds to capture prey – or avoid being captured. Now, for the first time, scientists have observed the use of ultra-fast action in a very specific scenario: as a means of escaping sexual cannibalism. Scientists have discovered male spiders of the species…
