Elephants' dietary habits are similar to humans: Study
Updated : 2 years, 8 months ago IST
The findings were reported in the journal Royal Society Open Science. Researchers have found elephants vary their diets based not only on what is available but also on their preferences and physiological needs. Elephants may vary what they eat for dinner every night just like humans.

Study illustrates how cells choose DNA repair methods
Updated : 2 years, 9 months ago IST
DNA is usually regarded as the blueprint for life and is essential for an organism to perform biological tasks. A range of factors, including radical metabolites, radiation, and other hazardous substances, can cause DNA damage. Because DNA is a two-stranded molecule, it can be damaged on eit

Study reveals how cells select DNA damage repair pathways
Updated : 2 years, 9 months ago IST
DNA is widely recognized as the blueprint for life, and it is required for an organism to assist biological functions. DNA may be damaged by a variety of circumstances, including radical metabolites, radiation, and some toxic compounds. Because DNA is a two-stranded molecule, any one or both

Researchers find how liver cells control biological clock
Updated : 2 years, 10 months ago IST
To control their activity according to the time of day, organisms rely on a biological clock known as the 'circadian' clock. A central clock, made up of a collection of brain cells known as suprachiasmatic nuclei (SCN), synchronises the circadian clocks found in all of the body's organs, kno

Nature favours creatures in all sizes: Study
Updated : 2 years, 10 months ago IST
The researchers spent five years compiling and analyzing data about the size and biomass of every type of living organism on the planet -- from tiny one-celled organisms like soil archaea and bacteria to large organisms like blue whales and sequoia trees.

Researchers find how ambrosia beetles identify their food fungi by their s
Updated : 2 years, 11 months ago IST
Active agriculture is practised by several species of ambrosia beetles. They cultivate and look after food fungi in the wood of trees as social groups and control the growth of so-called weed fungi.

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
