How To Reproduce With Two Fathers - And No Biological Mother
At the International Summit on Human Genome Editing, held in March 2023 at the Francis Crick Institute in London, Japanese researcher Katsuhiko Hayashi stunned attendees when he explained how he had successfully reproduced mice from two male parents.

In Major Breakthrough, Mice Created With Two Fathers And No Mother Reach Adulthood
By using embryonic stem cell engineering, the researchers were able to reprogram the imprinted genes, effectively allowing the mice to develop with genetic material from two fathers.

Reef Sharks in French Polynesia Suffer Health Consequences From Feeding by Tourists
Blacktip reef sharks in French Polynesia are experiencing significant health issues due to frequent feeding by tourists. Studies show that sharks fed low-quality scraps, such as frozen squid and human leftovers, have altered metabolism, lower red blood cell levels, and reproductive changes. Males showed increased testosterone, while females at feed...

Research Shows Twin Births Were Common in Ancient Primate Evolution
Research suggests that ancient primates, including early humans, typically gave birth to twins, a common trait in their evolutionary history. Over time, singletons became more prevalent due to the survival advantages of larger, more developed offspring. This shift is linked to the evolution of primates' larger brains and bodies, requiring more ener...

Here's How Tibetan Women's Adapts to Thin Air in Extreme High Altitudes
Tibetan women living on the Tibetan Plateau have developed extraordinary adaptations to thrive in extreme high altitudes. New research from Case Western Reserve University highlights unique physiological traits, including blood and heart characteristics that optimise oxygen delivery. These adaptations are linked to the EPAS1 gene, passed down from ...

Human Evolution Unfolding Before Us In The High Altitudes Of Tibetan Plateau
A new study by Cynthia Beall of Case Western Reserve University reveals how Tibetan communities have evolved over 10,000 years to thrive in the low-oxygen environment of the Tibetan Plateau.

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.

Men's Eggs, Women's Sperm: Stem Cell Science May Change How We Reproduce
It may soon be possible to coax human skin cells into becoming functional eggs and sperm using a technique known as "in vitro gametogenesis". This involves the creation (genesis) of eggs and sperm (gametes) outside the human body.

Scientists Create Mice With Two Fathers In Major Breakthrough
The development is being hailed in the scientific community as it can open radical new possibilities for human reproduction.

Green Day's Billie Joe Armstrong To Renounce US Citizenship Over Supreme Court's Abortion Ruling
UN Human Rights chief Michelle Bachelet in a statement described this decision was a "major setback" for sexual and reproductive health across the US.

Scientists Create Albino Lizards To Study Vision Problems In Humans With Albinism
A powerful gene-editing technology known as CRISPR has led to recent breakthroughs in mice, plants and humans, but getting the technology to work on reptiles had proved impossible because of key reproductive differences.

Old Sperm Produces Healthier Offspring, New Study Finds
Study experts say the findings may have important implications for human reproduction and fertility, particularly in the context of assisted fertilisation technologies.

Scientists Create 'Mini Human Placenta' Organoids In A Lab Dish
Scientists in Britain have succeeded in creating mini human placenta organoids which they say will transform scientific understanding of reproductive disorders such as pre-eclampsia and miscarriage.

World Population Day: 10 Facts You Must Know
World Population Day, a United Nations' initiative celebrated every year on July 11 to raise awareness about the exploding world population, focuses on reproductive rights this year to mark 50 years since family planning won recognition as a human right.

World Population Day 2019: What Is The Importance Of Population Day?
World Population Day: The primary aim of this initiative is to increase awareness about reproductive health problems among the people. This is due to the fact that a large number of pregnant women succumb to poor reproductive health.
