Parasitic wasps use calcium pump to block fruit fly immunity
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
Nanosuits help small creatures survive a vacuum
Finding Nematostella: An ancient sea creature
A study of tentacle-formation in a sea anemone shows how epithelial cells form elongated structures and puts the spotlight on a new model organism.
Prehistoric bugs from 230 million years ago found in amber (Update)
(Phys.org)—An international team of scientists has discovered the oldest record of arthropods—invertebrate animals that include insects, arachnids, and crustaceans—preserved in amber. The specimens, ...
Sex-deprived fruit flies drink more alcohol: New study could uncover answers for human addictions
Sexually deprived male fruit flies exhibit a pattern of behavior that seems ripped from the pages of a sad-sack Raymond Carver story: when female fruit flies reject their sexual advances, the males are driven ...
Fruit flies use alcohol as a drug to kill parasites
Fruit flies infected with a blood-borne parasite consume alcohol to self-medicate, a behavior that greatly increases their survival rate, an Emory University study finds.
Fruit flies medicate their larvae with alcohol
Sex chromosome evolution tracked in fruit fly
500 years ago, yeast's epic journey gave rise to lager beer
(PhysOrg.com) -- In the 15th century, when Europeans first began moving people and goods across the Atlantic, a microscopic stowaway somehow made its way to the caves and monasteries of Bavaria.
Discovery of wound-healing genes in flies could mitigate human skin ailments
Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.
New species appear to arise from sudden changes
(Phys.org)—Folmer Bokma, researcher at Umeå University, explains that living species have a limited ability to adapt to the environment. His results suggest that species do not change gradually, as the modern evolutionary ...
New study strengthens olfactory vibration-sensing theory
Reproductive tract secretions elicit ovulation
Eggs take a long time to produce in the ovary, and thus are one of a body's precious resources. It has been theorized that the body has mechanisms to help the ovary ensure that ovulated eggs enter the reproductive tract at ...
Researchers identify genetic sequence that helps to coordinate synthesis of DNA-packaging proteins
Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils. When these spool-like proteins ...
