A new study led by University of Maryland physicists sheds light on the cellular processes that regulate genes. Published in the journal Science Advances, the paper explains how the dynamics of a polymer called chromatin—the ...

Researchers characterize tardigrade species richness in Denmark

They're found on Mount Everest, in the deep seas, aboard the International Space Station and thousands of them have even crash landed and been spilled onto the moon. The microscopic water bear has a nearly unfathomable ability ...

Biologists find what colors a butterfly's world

As butterflies flit among flowers, they don't all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. ...

Researchers engineer bacteria that can detect tumor DNA

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of ...

Researchers identify peptides for pollen tube growth in rice

Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, hydrate, and germinate ...
