Most IVF ‘add-on’ treatments have no effect on fertility or remain unproven, study says
Most IVF ‘add-on’ treatments have no effect on fertility or remain unproven, study says
Review shows majority of procedures offered alongside standard IVF not backed by reliable evidence Most IVF “add-on” treatments sold to people hoping to boost their chances of having children are not backed by reliable evidence, fail to boost fertility and may be a complete waste

Long-lived families reveal a rare genetic clue to healthy aging
A study of long-lived families has identified rare genetic variants that may help people stay healthier for much longer as they age. One standout mutation appears to temper inflammation, potentially delaying disease and extending years of healthy living.
Real-time imaging reveals 'RNA hub' driving adaptive immune response
A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled DNA damage and repair that alter the genetic information
One tiny mutation may explain how bat viruses become human threats
One tiny mutation may explain how bat viruses become human threats
Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune system fights back or gets sup

Why South Africa’s leopards shrank to half their normal size
A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after

Sicily remained a medieval melting pot despite major political and religious upheavals, an
Sicilian populations have been genetically diverse for many centuries, and they have remained that way even through major regime changes and religious transitions, according to a study published in PLOS One by Aurore Monnereau of the University of York, U.K., and colleagues.

Synthetic DNA toolkit expands scientists' ability to recognize genetic targets
A new method for recognizing and targeting DNA that dramatically expands the range of genetic sequences scientists can identify has been developed by experts at the University of Portsmouth. Published this week in Nature Communications, the research opens new possibilities for ge
Nature or nurture: can genes make us behave ‘badly’? – podcast
How much do our genes determine about our lives, and could they influence traits like risk-taking, antisocial behaviour or even violence? Ian Sample talks to Kathryn Paige Harden, a behavioural geneticist and professor of psychology at the University of Texas at Austin who studie

Tiny DNA 'hitchhikers' may be reshaping life in thawing Arctic soils
Amid the peatlands of northern Sweden, billions of microbes are quietly rewriting their genetic playbooks—and doing so far more often than scientists realized.
