Harmful fungi cause enormous agricultural losses. Conventional techniques for combating them involve the use of poisonous fungicides. Researchers at Karlsruhe Institute of Technology (KIT), working with partners from Germany, France, and Switzerland on the DialogProTec project, have developed environmentally safe alternatives that trick the pathogens’ chemical communication with plants. Now that the research has been completed, the new technology is ready for use.

Johns Hopkins Medicine scientists report they have probed the atomic structure of proteins to add to evidence that the wobbles, shakes and quivers of proteins play a critical role in their ability to function. The findings of the research may help scientists design new drugs that can modify or disrupt the intricate “dances” of proteins to alter their functions.

Researchers reporting in ACS Central Science have used lasers to precisely control neutrophils — a type of white blood cell — as a natural, biocompatible microrobot in living fish. The “neutrobots” performed multiple tasks, showing they could someday deliver drugs to precise locations in the body.

To develop new COVID-19 medications, researchers are working to target nsp13, a protein coronaviruses need to replicate. In ACS Infectious Diseases, researchers describe a new approach to identifying molecules that interfere with this protein, a step toward developing pan-coronavirus antivirals.

Helical nucleocapsids in infected cells are composed of Marburg viral genomic RNA and nucleoproteins, or NPs, that are structurally similar to those of the Ebola virus. Future drug development may be possible based on the targeting of nucleocapsid formation, which may inhibit the Marburg virus' ability to replicate.

After almost two decades of synchrotron experiments, Caltech scientists have captured a clear picture of a cell’s nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell’s nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions.

Scientists suggest that water’s so-called “proton quantum effect” may be at the heart of many of the liquid’s strange properties. In this experiment with ultrafast electron diffraction, scientists observed how the hydrogen atoms in water molecules tug and push neighboring molecules when water is excited with laser light. This marks the first time that scientists have directly observed this effect in water.
