We estimated key epidemiological parameters for scabies, a disease affecting 400M people globally that's been rising across Europe. These are the first estimates of serial interval, R0 and Rt.

Long-sought environmental law reform is finally here. But will the compromise deal actually protect nature?
After years of failed attempts, Australia’s environmental laws are finally getting an overhaul. But will they stop the damage done to nature?

We have no answers from our institutions as to why Go8 universities endorsed BCA's regressive EPBC recommendations

But 90 of us have signed an 'Independent statement on the Group of Eight’s position on EPBC Act reforms'

🙏 Prof Justine Bell-James for writing & coordinating the independent statement
Independent statement on the Group of Eight’s position on EPBC Act reforms The federal Parliament is currently considering amendments to the flagship federal environmental legislation, the Environment Protection and Biodiversity Conservation Act 1999 (‘EPBC Act’). This is a once-in-a-generation opportunity to strengthen environmental protections to reverse Australia’s current trajectory of extinctions and biodiversity loss. We are academics at the institutions in the Group of Eight (Go8), with expertise in biodiversity conservation science, climate science, policy, economics and law. We support amendments to the EPBC Act to strengthen protections for biodiversity and remove ministerial discretion and legal loopholes, in order to create a level playing field for businesses, and make environmental protection and recovery central to all decision-making processes under the Act. We note that the Go8 has signed a statement by the Business Council of Australia endorsing amendments that will weaken the Act’s protection for the environment. This statement does not reflect the world leading conservation research being carried out at our institutions. It also does not reflect the extensive evidence-based advice provided by experts based at Go8 institutions during the review and consultation processes over the past five years. We disagree with this statement, and the Go8’s endorsement of it.

Half the breeding population of Elephant Seals on South Georgia lost to H5N1 (bird flu). The impact this will have on the species, the local food web, and even ocean fertilization is hard to comprehend.

Wetlands are rare and exceptional, even small ones.

Intrinsically valuable, they also:
🌱 Offer habitat for plants, insects, amphibians and birds
🌊 Absorb stormwater, buffering against floods
🌍 Filter and reduce pollutants, improving water quality

The CDC updated its vaccine page to claim "vaccines do not cause autism" is "not evidence-based" and studies were "ignored." This is an outrage. Decades of research have found no link. This isn't science, it's RFK Jr. using the CDC as propaganda. Children will die because of this.
