Scientists discovered how ecdysone initiates a biochemical cascade controlling genes that destroy salivary gland tissues during Drosophila metamorphosis. The study reveals key components of the 'death cascade' and suggests potential connections to mammalian cell death programs.
The Drosophila melanogaster fruit fly genome has been sequenced in full, with a focus on physical maps to ensure accuracy. The completion of the genome sequence is significant, as it reveals connections between fruit fly and human genes, offering insights into diseases such as cancer, kidney disease, and metabolic disorders.
Researchers at the University of Glasgow have identified a complex of proteins that activate cell growth and division protein E2F, leading to excessive cell division and cancer. This breakthrough provides an opportunity to develop small molecule drugs that can arrest E2F activity and prevent tumour cell proliferation.
The Drosophila genome sequence has been completed, providing valuable insights into human diseases and animal development. The sequence data reveals homologues for 60% of known genetic flaws causing disease in humans and 70% of genes involved in human cancers.
Researchers at Virginia Tech found that the amount of lead in the environment from bullets on battlefields is not a significant concern for water quality, with no contamination detected off range. However, they discovered that shot impacts cause significant damage to trees up to 140 meters beyond the range.
The Manatee Protection System uses acoustic sensors to detect manatees in the Port Canaveral locks, preventing collisions and saving their lives. The system's advanced technology, developed by ONR-supported scientists, has already saved five manatees during installation and early testing.
A new study suggests that mothers' depression may cause their daughters to enter puberty earlier. Researchers found a correlation between maternal depression and the timing of puberty in adolescent girls. The study also discovered a link between exposure to unrelated adult men, such as stepfathers, and early puberty in girls.
Researchers studying clumsy fruit flies have identified a central component of the sensory machinery that underlies balance, touch and hearing. They discovered a molecule called an ion channel, which is pried open when a bristle is deflected, triggering a nerve impulse.
