Updated : 3 years, 1 month ago IST
Scientists from the Institut Pasteur, Universite Paris Cite, the CNRS and the College de France have used paleogenomics to trace 10,000 years of human immune system evolution. They analyzed the genomes of more than 2,800 individuals who lived in Europe over the past ten millennia. They were

Study explains why older fathers pass on more genetic mutations to their o
Updated : 2 years, 4 months ago IST
The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn't, however, clarify why older fathers pass on more mutations than younger ones do. The mechanisms that might un

Researchers discover a dependency of glioblastoma on biotin distribution
Updated : 3 years, 2 months ago IST
Glioblastoma is the most lethal and malignant adult brain cancer that may arise from the neuroglial stem or progenitor cells. Certain gene mutations or those with a known history of other cancers and radiation therapy may predispose patients to develop brain cancer. Tumour relapse is invaria

Updated : 3 years, 2 months ago IST
According to the CDC, the XBB.1.5 omicron subvariant as of this week has pushed out the BQ.1 and the BQ.1.1 subvariants from their previous positions as the most detected coronavirus mutations.

Research: Enzyme that protects against viruses could fuel cancer evolution
Updated : 3 years, 2 months ago IST
An enzyme that defends human cells against viruses can help drive cancer evolution towards greater malignancy by causing myriad mutations in cancer cells, according to a study led by investigators at Weill Cornell Medicine. The finding suggests that the enzyme may be a potential target for f

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.

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
