Researchers find how to compensate for loss of gene function
Updated : 3 years ago IST
Living organisms have a knack for persisting in the face of challenges. For instance, when genes malfunction, organisms may be able to compensate by activating redundant genes with similar functions, called paralogs.

Here's why microbes in the deep ocean live without sunlight
Updated : 3 years, 1 month ago IST
A new study reverses the idea that the bulk of life in the ocean is fueled by photosynthesis via sunshine, revealing that many ocean microbes in fact get their energy from hydrogen and carbon monoxide. It has always been a mystery as to how microbes growing in deepest parts of the sea surviv

Aquatic organisms respond to flooding, drought disturbance in different wa
Updated : 3 years, 1 month ago IST
Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new Penn State-led study that employed a novel method to assess the stability of stream ecosystems.

How species adapt: Ancestral variation guides future environmental adaptat
Updated : 3 years, 1 month ago IST
The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity.

Research shows that exercise promotes a molecular profile in muscle
Updated : 3 years, 1 month ago IST
A recent paper published in the Journal of Physiology deepened the case for the youthfulness-promoting effects of exercise on ageing organisms, building on previous work done with lab mice nearing the end of their natural lifespan that had access to a weighted exercise wheel.

New study explores circadian clock of fruit fly
Updated : 3 years, 2 months ago IST
The higher the temperatures, the faster physiological processes are. However, there is an exception: the so-called circadian clock, which regulates the sleep-wake cycle in organisms.
