Plant study hints evolution may be predictable
Updated : 3 years, 3 months ago IST
Evolution has long been viewed as a rather random process, with the traits of species shaped by chance mutations and environmental events and therefore largely unpredictable.

Cellular secrets of aging unlocked by researchers
Updated : 3 years, 3 months ago IST
New research has uncovered how genetic changes that accumulate slowly in blood stem cells throughout life are likely to be responsible for the dramatic change in blood production after the age of 70.

Research: Enzymes could be key to understanding how DNA mutates
Updated : 3 years, 3 months ago IST
Enzymes, which are crucial to controlling how cells replicate in the human body, could be the very ingredient that encourages DNA to spontaneously mutate - causing potentially permanent genetic errors, according to new research from the University of Surrey.

Study finds how Error-prone DNA lead to BRCA1 related cancer
Updated : 3 years, 3 months ago IST
Researchers have identified that people who inherit a faulty copy of the BRCA1 gene may develop mutations and cancer due to error-prone DNA replication and repair. When these individuals' cells are under stress, replication of the normal BRCA1 gene stalls because of the highly repetitive DNA

Rare mutations may have big impact on schizophrenia pathology
Updated : 3 years, 4 months ago IST
Researchers have long searched for genetic influences in schizophrenia, a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. However, the disease's genetic mutations have been identified in only a small fraction few

Study suggests key protein can predict survival of lung cancer patients
Updated : 3 years, 4 months ago IST
A group, led by researchers from the University of Edinburgh, discovered that TLR2 helps control some of the body's defense mechanisms when cancerous mutations occur in cells.

Research: Growing motor neurons guided by 'love-hate relationship' with bl
Updated : 3 years, 4 months ago IST
When neurons involved in movement called motor neurons form, they must build connections that reach from the brain, brainstem, or spinal cord all the way to the head, arms, or the tips of the toes. How neurons navigate these systems and "decide" where and how to grow has largely been a myste

Researchers discover mutations linked to increase risk of ovarian cancer
Updated : 3 years, 4 months ago IST
Study discovered four new areas of the human genome that contain genetic variations or mutations that enhance women's chance of getting epithelial ovarian cancer, the most frequent kind of ovarian cancer.

Study sheds light on new clues into a serious neurodegenerative disease
Updated : 3 years, 4 months ago IST
Dementia encompasses a range of neurodegenerative conditions that lead to memory loss and cognitive deficiencies and affect some 55 million people worldwide. Yet despite its prevalence, there are few effective treatments, in part because scientists still don't understand how exactly dementia

Findings create new model for investigating diseases related to circadian
Updated : 3 years, 4 months ago IST
Washington [US], October 21 (ANI): Research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical treatments.
