The big clean up after stress

Toxic substances, nutrient shortage, viral infection, heat and many other events trigger stress responses in cells. In such cases, the affected cells launch a programme which tries to protect them against stress-related damages. ...

The mechanisms of plant aging

European researchers investigated the molecular mechanisms that drive stress-related responses that cause aging and death in plants. The goal is to generate resilient crop varieties.

New method to replicate harsh conditions for materials

Confining a plasma jet can be stress-inducing, especially on the shielding materials. Noting the limits inherent in the test methods currently used for such materials, Professor Patrizio Antici and his colleagues have proposed ...

Can models predict grid tolerance to environmental extremes?

Understanding the environmental conditions associated with stress on the electric grid has important practical considerations, but also represents a complex scientific and modeling challenge. A research team led by scientists ...

Hibernating ribosomes help bacteria survive

In the second of two high-profile articles published in recent weeks, Saint Louis University scientist Mee-Ngan F. Yap, Ph.D., in collaboration with the laboratories of 2009 Nobel laureate in chemistry Ada Yonath at the Weizmann ...

Stressed lemurs have worse chances of survival

High levels of hair cortisol—a sign of long-term stress—are associated with reduced survival in wild grey mouse lemurs (Microcebus murinus), according to a study published in the open access journal BMC Ecology.

What it takes to recover from drought

Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.
