Wa hoo! Our paper in Science is out today, revealing why some prey use conspicuous warning colouration while others use camouflaging colours. A huge global collaboration under incredible leadership by Iliana Medina and @wlallen.bsky.social www.science.org/doi/10.1126/...

Global selection on insect antipredator coloration
Natural selection has repeatedly led to the evolution of two alternative antipredator color strategies—camouflage to avoid detection and aposematism to advertise unprofitability—but we lack understand...

How long will you live? New evidence says it’s much more about your choices than your genes
Is our lifespan primarily dictated by our genetics, or do our behaviour and environment play the more important role?

Scientific misconduct is on the rise. But what exactly is it?
In 2023, more than 10,000 research papers were retracted because of scientific misconduct. But it’s not always deliberate.

Lethal second-generation rat poisons are killing endangered quolls and Tasmanian devils
Second generation rat poisons are so potent that they’re banned for home use in Europe and North America. But here, you can pick them up at Bunnings or Coles.

There is declining trust in Australian unis. Federal government policy is a big part of the problem
According to some observers, the ‘hottest topic’ for 2025 is whether universities have lost the public’s support to operate.

Australia spends $714 per person on roads every year – but just 90 cents goes to walking, wheeling and cycling
Walking and cycling get 90c per person each year from the Australian government. What if that figure rose to $5, $10 or $15?

New review paper! @1jonevans.bsky.social @pacogarciagonzalez.bsky.social and I ask whether mature sperm cells might actively express genes. Really proud to see this one out - has been a long, difficult journey through much skepticism to publication. royalsocietypublishing.org/doi/10.1098/...

Silent cells? Potential for context-dependent gene expression in mature sperm | Proceedings of the Royal Society B: Biological Sciences
Sperm are traditionally viewed as transcriptionally and translationally silent cells. However, observations that components of the cellular machinery of gene expression are maintained in ejaculated sp...

A Perspective explores the consequences of bypassing natural selection in assisted reproduction—including the filtering of sperm for quality inside the female reproductive tract—and options to mimic such selection to reduce risks to offspring. In PNAS Nexus: academic.oup.com/pnasnexus/ar...
Assisted reproductive technologies (ART) can bypass female-modulated sperm selection (top of figure) that ensure that genetically compatible or competent sperm are used for fertilization. ART can also introduce a range of novel environmental stressors (bottom of figure) that generate epigenetic modifications in offspring. Failure to design procedures that both mimic natural conditions and mitigate the harmful effect of unnatural environmental conditions during ART can impact the health trajectories of ART offspring and potentially their descendants.

ARC says they’ll release the Discovery Projects 2025 outcomes tomorrow. Recently, outcomes announcements have tended to happen at/around 11am Canberra time. My bot will pick up the announcement in RMS’s database and post immediately. Good luck!
