New era of space research launched by IceCube Observatory and global team of astronomers
A flaring supermassive black hole 3.7 billion light-years from Earth in the constellation Orion is the suspected source of a super-high-energy subatomic particle -- a neutrino -- that has launched a new era of space research. Credit: Nate Follmer, Penn State
The hidden complexity underlying a common cause of autism: Uncovering genetic interactions responsible for neurodevelopmental disorders
Illustration of chromosome 16 showing the 14 fly counterparts of the 25 human genes located in a deletion on the chromosome that is associated with autism risk. Researchers used RNA interference (RNAi) to the reduce the expression of these genes individually and in tandem to test how the interactions of these genes modulate neurodevelopmental symptoms associated with the deletion. Interactions between genes that either enhance or suppress the affect of reduced expression are shown by red or blue lines.
'Nuru' becomes African farmers' newest ally against fall armyworm
Fall armyworm larvae have caused an estimated $2.5 billion to $6.2 billion in damage annually to maize in sub-Saharan Africa since the pest arrived there in 2016. Image: John C. French Sr., Bugwood.org
Compound made inside human body stops viruses from replicating
A structural model of viperin, a naturally occurring enzyme in humans that is known to have antiviral effects on viruses such as West Nile, hepatitis C, rabies, and HIV. A new study led by researchers from Penn State and the Albert Einstein College of Medicine reveals the mode of action of viperin, which facilitates an important reaction that results in the production of ddhCTP, a molecule that prevents viruses from copying their genetic material.

Mechanical force controls the speed of protein synthesis
Researchers discovered that proteins, represented by the black line, exert a mechanical force as they exit the molecular machine where they are synthesized, represented in red. That force moderates the speed of protein synthesis. Image: Benjamin Fritch
Altered body odor indicates malaria even if microscope doesn't
An Anopheles stephensi mosquito is obtaining a blood meal from a human host through its pointed proboscis. Note the droplet of blood being expelled from the abdomen after having engorged itself on its host’s blood. This mosquito is a known malarial vector with a distribution that ranges from Egypt all the way to China. Image: Jim Gathany / CDC
