Detecting Odors on the Edge: Researchers Decipher How Insects Smell More with Less
While humans feature a sophisticated sense of smell, insects have a much more basic olfactory system. Yet they depend upon smell to survive. Scientists have figured out how fruit flies use a simple but efficient system to recognize odors, and the answer lies at the edges of their antennae.
How the Brain’s Internal Compass Guides the Body
A study in fruit flies reveals how the brain’s compass and steering regions make course corrections
Genetics of attraction: mate choice in fruit flies
Genetic quality or genetic compatibility? What do female fruit flies prioritize when mating? Researchers at the University of Zurich show that both factors are important at different stages of the reproductive process and that females use targeted strategies to optimize the fitness of their offspring.
Gene links exercise endurance, cold tolerance and cellular maintenance in flies
As the days get shorter and chillier in the northern hemisphere, those who choose to work out in the mornings might find it harder to get up and running. A study in PNAS identifies a protein that, when missing, makes exercising in the cold that much harder—that is, at least in fruit flies.
Mating causes ‘jet lag’ in female fruit flies, changing behavior
An innovative technique from Cornell University researchers finds seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly’s circadian clock.
How a SARS-CoV-2 Virus Protein Damages the Heart
Researchers at the University of Maryland School of Medicine’s (UMSOM) Center for Precision Disease Modeling identified how a specific protein in SARS-CoV-2, the virus responsible for COVID-19, damages heart tissue. They then used a drug to reverse the toxic effects of that protein on the heart.
Research News Tip Sheet: Story Ideas from Johns Hopkins Medicine
During the COVID-19 pandemic, Johns Hopkins Medicine Media Relations is focused on disseminating current, accurate and useful information to the public via the media. As part of that effort, we are distributing our “COVID-19 Tip Sheet: Story Ideas from Johns Hopkins” every other Tuesday.
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.
Sleep, Death and … the Gut?
A new study finds in sleep-deprived fruit flies, premature death is always preceded by the accumulation of reactive oxidative species in the gut. Antioxidant compounds that neutralize ROS allow sleep-deprived flies to have normal lifespans.
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.
Flyception 2.0: New Imaging Technology Tracks Complex Social Behavior
An advanced imaging technology developed at UC San Diego is allowing scientists unprecedented access into brain activities during intricate behaviors. The “Flyception2” has produced the first-ever picture of what happens in the brain during mating in any organism.
