Amazon deforestation and number of fires show summer of 2019 not a 'normal' year

The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was 'normal' and 'below the historical average'.An international team of scientists writing in the journal Global Change Biology say the number of active fires in August was actually

Gear up and cook the perfect Thanksgiving dinner

Thanksgiving is just a regular dinner. With a ton more menu options. And your in-laws. And your sister whose political views radically oppose those of your grandfather. What could possibly go wrong?

How nematodes outsmart the defenses of pests

The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become immune against these compounds in turn, which enhances their ability to fight the western corn rootworm, as researchers at the University of Bern show. This mechanism may co
