Scientists have developed a way to identify the beginning of every gene -- known as a translation start site or a start codon -- in bacterial cell DNA with a single experiment and, through this method, they have shown that an individual gene is capable of coding for more than one protein.
An interdisciplinary team of scientists has identified a new mobile DNA element in the Wolbachia parasite, which may contribute to improved control strategies for mosquito vectors of diseases such as Dengue and West Nile virus.
Meadows adjacent to high-intensity agricultural areas are home to less than half the number of butterfly species than areas in nature preserves. The number of individuals is even down to one-third of that number.
In nature, males eager attempts to mate with females can be so extreme that they will harm females.
