Scientists mapped genomes of bed bug strains, identifying 729 mutations linked to insecticide resistance, offering insights for improved pest control. Scientists have successfully mapped near-complete and highly accurate genomes for two strains of bed bugs: one highly susceptible to insecticides and another “superstrain” that is roughly 20,000 times more resistant. This achievement provides the most comprehensive view yet of the genetic mutations behind insecticide resistance. The findings were published in the journal Insects. While bed bugs are not known to transmit diseases to humans, their bites can cause itchy rashes and secondary infections. Insecticide use, including the now-banned DDT, nearly...

The remains of a burnt beetle found in a grain of wheat about 3,500 years old provided a group of researchers from Bar-Ilan University with a key to a question the Bible left without a definite answer: How did Joseph the Dreamer, who became the viceroy to the king of Egypt, succeed in preserving the grain during the seven lean years and prevent Egypt's population from starving? According to the description in the book of Genesis, during the seven years of plenty in Egypt, Joseph had all the wheat collected in silos. "And he gathered up all the food of...
