New Giant Virus Group Reported
Diana Kwon | Apr 6, 2017
A genomic analysis of “Klosneuviruses” suggests that they evolved from small viruses that accumulated genetic material over time, but not all virologists are convinced.
Anti-Flavivirus Antibodies Enhance Zika Infection in Mice
Anna Azvolinsky | Mar 30, 2017
Researchers report evidence of antibody-dependent enhancement in a Zika-infected, immunocompromised mouse model.
Experimental MERS Treatments Target Host Cell Receptor
Ashley Yeager | Mar 30, 2017
Researchers are searching for ways to prevent the coronavirus from attaching to DPP-4 receptors, blocking it from invading and replicating within host cells.
Study: Diet Contributes to Brain Size
Diana Kwon | Mar 29, 2017
The results of a historical primate behavior analysis suggest that species with fruit-filled diets evolved larger brains.
Dinosaur Phylogenetic Tree Shake-Up
Jef Akst | Mar 24, 2017
An analysis of 74 dinosaur species leads a group of researchers to reorganize the extinct animals’ evolutionary history.
Sharks May Have Evolved from Acanthodians
Joshua A. Krisch | Mar 14, 2017
Analysis of an ancient shark fossil provides the strongest evidence to date that modern sharks derive from a class of 400 million–year-old bony fish.
Vision Helped Ancestral Fish Adapt to Life on Land
Diana Kwon | Mar 8, 2017
“Buena vista” hypothesis suggests that changes in the sizes of eyes, rather than a shift from fins to limbs, led fish to transition to land more than 300 million years ago.
Understanding the Roots of Human Musicality
Catherine Offord | Mar 1, 2017
Researchers are using multiple methods to study the origins of humans’ capacity to process and produce music, and there’s no shortage of debate about the results.
Study: Zika Shrinks Testicular Tissue in Mice
Bob Grant | Feb 23, 2017
The virus may persist in testes even after the infection is no longer detectable in blood, leading to sexual transmission of the disease and fertility impairments.
Ancient Marine Reptile Birthed Live Young
Bob Grant | Feb 15, 2017
Researchers have described a pregnant
, and the fossilized remains suggest that the massive animal did not lay eggs, as previously suspected.
