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

Study finds that bats experience hearing loss in older age
Updated : 2 years, 11 months ago IST
Many mammals suffer from hearing loss as they age, but bats were thought to be immune due to the importance of hearing for echolocation. However, Israeli researchers discovered that bats, like humans, lose their hearing as they age

Study reveals influence of krill availability on humpback whale pregnancie
Updated : 3 years, 1 month ago IST
Scientists show reduced krill supplies lead to fewer pregnancies in humpback whales, a finding that could have major implications for industrial krill fishing. Data from Antarctica show more humpback whales get pregnant after years with abundant krill than after years when krill were less pl

Study concludes evolution of uniquely human DNA was a balancing act
Updated : 3 years, 2 months ago IST
The difference between humans and chimpanzees lies in only one per cent of their DNA. Human accelerated regions (HARs) are parts of the genome with an unexpected amount of these differences. HARs were stable in mammals for millennia but quickly changed in early humans.

Study finds how high-energy X-rays trace destruction in bone samples
Updated : 3 years, 2 months ago IST
X-rays cause damage to living tissue, there are clear medical reasons to limit your exposure to radiation. Researchers use increasingly powerful X-ray sources in basic research on the properties and characteristics of mineralised tissue samples such as bone.
