Chromosomal instability is a phenomenon characterised by rapid changes in the number and structure of chromosomes during cell division. It is very common in solid tumours and it is linked to the aggressive spread of cancer, that is to say, metastasis.

Fly Toolkit Created for Investigating COVID-19 Infection Mechanisms
Researchers have created a resource for analyzing how viruses infect human cells. The fruit fly-based toolkit provides a shortcut for assessing SARS-CoV-2 genes and understanding how they interact with human proteins, offering researchers a resource for new COVID-related drug therapies.
The feeling of hunger itself may slow aging
While it has been long understood that limiting the amount of food eaten can promote healthy aging in a wide range of animals, including humans, a new study from University of Michigan has revealed that the feeling of hunger itself may be enough to slow aging.
How fruit flies feast for pleasure as well as necessity
Researchers have begun to explore the underlying neural activity of eating behaviours in fruit flies to better understand the motives that drive feeding.
Researchers identify the neurons that synchronise female preferences with male courtship songs in fruit flies
When it comes to courtship, it is important to ensure that one is interacting with a member of the same species.
When bugs swipe left
Vinegar flies use pheromones to ensure that they court and mate with members of the same species. As new fly species split off from a common ancestor, but continue to share the same environment, they need a way to rapidly diversify their pheromones to suppress inter-species mating. New research identifies a link between the genetic instructions for the production and perception of sex pheromones.
New Approach Methodologies, Single Cell RNAseq, and More Featured in 2021 Toxicological Sciences
Toxicological Sciences delivers cutting-edge research in toxicology in the areas of clinical and translational toxicology, emerging technologies, and more in the August 2021 issue.
Research suggests fly brains make predictions — possibly by using universal design principles
New research in flies indicates that prediction may be a universal principle among animal nervous systems to enable rapid behavioral changes.
Study shows how some neurons compensate for death of their neighbors
By studying several neuron pairs that innervate distinct muscles in a fruit fly model, researchers found that some neurons compensate for the loss of a neighboring partner.
Scientists Use Geometry to Track Cell Migrations
A team of physicists and biologists investigate the effect that the geometry of the biological environment has on cellular movement. Their findings are published in the journal Science.
Fruit flies reveal new insights into space travel’s effect on the heart
Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that fruit flies that spent several weeks on the International Space Station (ISS)—about half of their lives—experienced profound structural and biochemical changes to their hearts.
Twisting and Turning: Unraveling What Causes Asymmetry
Chirality is a type of asymmetry where something can’t overlap with its mirror image, like our hands. Michael Ostap, Ph.D., is researching what causes chirality on a molecular level to better understand embryonic development and how it can go wrong.
What Induces Sleep? For Fruit Flies It’s Stress at the Cellular Level
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body.
