Atomic 'mismatch' creates nano 'dumbbells'

Like snowflakes, nanoparticles come in a wide variety of shapes and sizes. The geometry of a nanoparticle is often as influential as its chemical makeup in determining how it behaves, from its catalytic properties to its ...

Some plants evolve tolerance to deer

Rampant deer have long been munching away on forest plants and altering ecosystems, but new evidence suggests some plants are evolving tolerance to being eaten.

Condors with greater independence have higher lead levels

Power generation technology for ammonia combustion in a gas turbine

Researchers have successfully generated 21 kW of power using a gas turbine driven by bifuel where kerosene equivalent to 30 % was replaced by ammonia in a commissioned research under the Energy Carrier project of the Cross-Ministerial ...

'Sleeping dogs' threaten the genome as we age

The genomes of many organisms, humans included, are littered with repetitive sequences of DNA called retrotransposons. In a new "Perspective" in the journal Science, four biologists write that while most retrotransposons ...
