Native bacteria block Wolbachia from being passed to mosquito progeny

Researchers discovered that a type of bacteria called Asaia blocks invasion of Wolbachia into mosquitoes' germlines, stopping the insects from transmitting Wolbachia to their offspring. This finding provides a potential answer to why some insect species are infected with Wolbachia while others are not.

Astrophysicists detect destruction of 3 stars by black holes

Researchers from Moscow Institute of Physics and Technology have reported detecting three possible occasions of star destruction by supermassive black holes at galaxy centers. Using data from X-ray orbiting observatories ROSAT and XMM-Newton, they identified three X-ray sources with significant dimming, suggesting the death of a star i...

Scientists unravel mystery of brain cell growth

Researchers have solved a longstanding puzzle in neuroscience by revealing the three-dimensional atomic structure of netrin-1, a guidance protein that can attract or repel brain cells. By understanding how this protein works, scientists may be able to develop new ways to steer cell behavior and potentially treat diseases such as cancer.
