Lack Of Protein May Trigger DNA Damage And Reduce Lifespans In Females, Finds Study
Findings published in the journal Nature show that 'SIRT7', a protein involved in how cells respond to stress and ageing, plays a critical role in maintaining the health of the X chromosome, one of two sex chromosomes that determine one's biological sex.

Exposure To High Temperatures Linked With Decline In Male Births: Study
Exposure to high temperatures during pregnancy is linked to a decline in male births in India and sub-Saharan Africa, according to new research.

Men Lose Their Y Chromosome As They Age. Scientists Thought It Didn't Matter - But Now We're Learning More
Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health.

Brain Ageing Could Be Fault Of Mothers, Study Suggests
The maternal X chromosome sped up biological ageing in the hippocampus - a brain area crucial for learning and memory.

Y Chromosome's Decline: Can Males Survive Without It in the Distant Future?
The human Y chromosome, crucial for male development in the embryo, has been steadily losing its genes over millions of years. Currently, the chromosome is down to just 45 genes from an original count of 1438, with scientists estimating that it could disappear entirely within 11 million years. This genetic deterioration has raised concerns about th...

Will Men Be Wiped Out By A Fading Y Chromosome? What Current Science Reveals
Y chromosome has significantly reduced in size over millions of years, raising the possibility of evolving new sex-determination systems and the emergence of different human species in the distant future.

Society Must Be Educated That Man's Chromosomes Decide Child's Gender: High Court
Parents who give daughter-in-laws a hard time for not being able to fulfil their desire of "preserving the family tree", need to be educated that it is their son and not his wife whose chromosomes will decide the child's gender, the High Court said.

Meet "Bionic Teen" From UK Who Feels No Pain, Hunger Or Fatigue Due To Rare Disorder
The teenager, Olivia Farnsworth, has a rare chromosome condition known as chromosome 6 deletion, which does not make her feel pain, hunger or fatigue.

Scientists Solve The Genetic Puzzle Y Chromosome
Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that could help guide research on infertility in men.

Children Inherit Intelligence From Mothers, Says Study
Mother's genes may determine how clever the children will be, whereas the father makes no difference to their intelligence levels, a new research suggests.

Male Without Y Chromosome: A Step Towards Better Understanding Sex Differentiation
Taking a step ahead to understand sex differentiation, a recent study has revealed that key sex-determining genes continue to operate in a mammalian species that lacks the Y chromosome.

Loss Of Y Chromosome May Up Alzheimer's Risk: Study
Men with blood cells that do not carry the Y chromosome are at greater risk of developing Alzheimer's disease, according to a new study that may lead to a simple test to diagnose the neurodegenerative disorder.

Lack Of A Gene Copy Can Trigger 25-Point Drop In IQ Levels: Study
Lack of a vital gene copy of Chromosome 16 may cause a 25-point drop in your IQ, a new study has claimed.

What 'Silences' X Chromosome In Girls Decoded
Scientists led by an Indian-origin researcher may have discovered what actually silences the X chromosome in girls, a finding that could lead to ways to counteract X-linked diseases in women.

Scientists create 'designer' chromosome
Scientists have created the first man-made chromosome for a complex-celled organism - a feat hailed on Friday as a big step towards acquiring the controversial ability to redesign plants or animals.
