Plant disease primarily spreads via roadsides

An analysis based on mathematical statistics more precise than those previously carried out uncovered the reason why powdery mildew fungi on Åland are most abundant in roadsides and crossings. The specific cause was the ...

Polymer films pass electron gun test

HSE researchers, jointly with colleagues from the RAN Institute of Organoelement Compounds and the RAN Institute of Physical Chemistry and Electrochemistry, have studied the properties of a polyarylene ether ketone-based ...

Condensins mutually interact to fold DNA into a zigzag structure

DNA in a cell is comparable to tangled spaghetti strands on a plate. To be able to divide DNA neatly between the two daughter cells during cell division, the cell organises this tangle into tightly packed chromosomes. A protein ...

New version of Earth model captures detailed climate dynamics

Earth supports a breathtaking range of geographies, ecosystems and environments, each of which harbors an equally impressive array of weather patterns and events. Climate is an aggregate of all these events averaged over ...

Electric solid propellant: Can it take the heat?

Electric solid propellants are being explored as a safer option for pyrotechnics, mining, and in-space propulsion because they only ignite with an electric current. But because all of these applications require high heat, ...

Current model for storing nuclear waste is incomplete

The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

Insect bites and warmer climate means double-trouble for plants

Recent models are telling us that, as our climate warms up, herbivores and pests will cause increased damage to agricultural crops. One study predicted that crop yield lost to insects increases 10 to 25 percent for every ...

Battling longer, more intense fire seasons

Fires in Australia have been burning for months. At least 28 people and hundreds of thousands of animals have died, and more than 15 million acres have been destroyed as firefighters work to squelch the blaze. Penn doctoral ...

Study finds salt nanoparticles are toxic to cancer cells

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles—more commonly known as salt—are toxic to cancer cells and ...
