Godartede bakterier kan gøre pesticider overflødige på marken Hvor stort udbyttet af sukkerrørsproduktionen i Brasilien bliver hvert år, afhænger mange steder af små orm kaldet nematoder. Ormene er skadedyr i jorden, og de angriber planters rødder. Omkring halvdelen af Brasiliens sukkerrørsareal på ni millioner hektar er plaget af nematoder, så sukkerrør ikke kan optage næringsstoffer effektivt og i stedet bliver svækket og mere udsat for svampe- og skadedy
Einstein's "Theory of Happiness" Teaches a Profound Truth Albert Einstein is, of course, world famous for coming up with the theory of relativity, which in many ways changed our conception of time and space. Einstein was also not averse to writing on matters other than physics and has offered many a pithy and poignant opinion on topics from love to anti-semitism to god. He also wrote what has been called “the theory of happiness,” which recently sold

Hiding Clear Ideas behind Unclear Words Chances are you know someone who thinks science is simultaneously complicated and boring. What a feat for a subject to be both at once, and what a challenge to convince such a someone that science is worth their time and attention. Some try to overcome these barriers by emphasizing how cool or relevant new results are, but unintended side effects from these approaches can deepen the void rather t
Dark Matter and Dark Energy Don’t Exist. New Theory Says the Universe Works Without Them Before the Hubble Space Telescope (HST), it was thought that the universe was slowing in its expansion and might someday fold back in on itself . In 1998, the HST revealed that rather than slowing, the rate of universal expansion is actually picking up. We still don’t know why. One explanation is dark energy . Rather than allowing the universe to expand at a constant rate, dark energy pushes it
Whose Smarter Cats or Dogs? Science Has Found a Clear Winner Ever wonder about the intelligence of various animals and how they measure up? Researchers at Vanderbilt University decided to find out.
