Reversing age-related fertility decline in male fruit flies: the crucial role of seminal fluid

University of Oxford
Peer-Reviewed Publication

As males age their reproductive success typically declines. A study in fruit flies, led by University of Oxford researchers has found that while old males do produce fewer offspring than young males, this is not because they have fewer sperm, but it is due to seminal fluid limitation. This study highlights the importance of the seminal fluid in reproductive success and may have crucial implications for improving animal fertility and IVF.

Cycle of coral bleaching on the Great Barrier Reef now at ‘catastrophic’ levels

University of Sydney
Peer-Reviewed Publication

The research by University of Sydney marine scientists highlights the complex interplay between heat stress, disease onset and coral mortality. It found that 66 percent of the colonies were bleached by February 2024 and 80 per cent by April. By July, 44 percent of the bleached colonies had died, with some coral genera, such as Acropora, experiencing a staggering 95 percent mortality rate.

Ancient viral DNA shapes early embryo development

Helmholtz Munich (Helmholtz Zentrum München Deutsches Forschungszentrum für Gesundheit und Umwelt (GmbH))
Peer-Reviewed Publication

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the genome, researchers at Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) have now revealed their crucial role in early embryo development.
