The persistent danger after landscape fires

Reactive oxygen species (ROS) cause oxidative stress at the cellular level. Research shows that this way, amongst others, they inhibit the germination capacity of plants, produce cytotoxins or exert toxic effects on aquatic ...

What causes algal blooms, and how we can stop them?

Outbreaks of algae have killed up to a million fish in the Murray Darling Basin over the last two weeks. The phenomena of "algae blooms", when the population of algae in a river rapidly grows and dies, can be devastating ...

Underwater defense: New ways to protect divers in the deep

Special Operations divers like Navy SEALs take on life-threatening risks such as enemy combatants and harsh environments. But another hazard is silent and unseen—oxygen toxicity, the result of breathing lethal levels of ...

Worm sugarcoats bacterial toxins to stave off death

(Phys.org)—Pathogenic bacteria kill their animal or plant hosts through the production of toxic molecules. But how do animals and plants defend themselves against these toxins? Researchers from the Boyce Thompson Institute ...

Unraveling plant reactions to injury

Better understanding of plant defense systems, and the potential to generate stress-tolerant plants and even new malaria drugs, may all stem from the documentation of a molecular mechanism that plays a significant role in ...
