The tail fibre of an extracellular contractile injection system (eCIS) from Photorhabdus asymbiotica recognizes targets expressed on eukaryotic host cells, and can be reprogrammed to target specific organisms and cell types for delivery of novel protein payloads.

Researchers uncover a new attack technique involving malicious SFX files! These files can hide hidden functionality, enabling persistent backdoor.
The World Health Organization confirmed an outbreak of the deadly Marburg virus disease in the central African country of Equatorial Guinea on February 13, 2023. To date, there have been 11 deaths suspected to be caused by the virus, with one case confirmed. Authorities are currently monitoring 48 contacts, four of whom have developed symptoms and three of whom are hospitalized as of publication. The WHO and the U.S. Centers for Disease Control and Prevention are assisting Equatorial Guinea in its efforts to stop the spread of the outbreak.
Marburg virus and the closely related Ebola virus belong to the filovirus family and are structurally similar. Both viruses cause severe disease and death in people, with fatality rates ranging from 22% to 90% depending on the outbreak. Patients infected by these viruses exhibit a wide range of similar symptoms, including fever, body aches, severe gastrointestinal symptoms like diarrhea and vomiting, lethargy and sometimes bleeding.
We are virologists who study Marburg, Ebola, and related viruses. Our laboratory has a long-standing interest in researching the underlying mechanisms of how these viruses cause disease in people. Learning more about how Marburg virus is transmitted from animals to humans and how it spreads between people is essential to preventing and limiting future outbreaks.

A new spin behavior has been found in the light-induced electron emission of tungsten ditelluride.
Through global-scale seismic imaging of Earth’s interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published today in Science Advances.
Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Subducted underground long ago as the Earth’s plates shifted, this ultra-low velocity zone, or ULVZ, is denser than the rest of the deep mantle, slowing seismic waves reverberating beneath the surface.
“Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought,” said Dr. Samantha Hansen, the George Lindahl III Endowed Professor in geological sciences at UA and lead author of the study. “Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet.”
“Are we predisposed to religion because it is hardwired in our genes?”
Does a predisposition to’religiosity’ or ‘belief’ provide humanity with survivor advantages? Does that mean there is a God gene?
