Article Synopsis
- Demographic rescue involves adding individuals to endangered populations to boost their numbers and prevent extinction, but its effectiveness is uncertain in the presence of diseases.
- A study was conducted using an aquatic crustacean, Daphnia dentifera, and a fungus pathogen, Metschnikowia bicuspidata, to investigate how pathogens affect demographic rescue outcomes.
- Results showed that while adding healthy individuals temporarily increased population size, populations with infected individuals ultimately had significantly lower abundance compared to those with no intervention, highlighting the risks of introducing diseased organisms during rescue efforts.*
Article Synopsis
- Carriers of BRCA1/2 pathogenic variants were studied to determine their risk of developing cancers during childhood, adolescence, and young adulthood (CAYA).
- Analysis of data from over 47,000 individuals revealed that while young women with BRCA1/2 mutations had a significantly increased risk of breast cancer in their 20s, no increased risk was found for other types of CAYA cancers.
- The study concluded that there's little evidence to support routine genetic testing for children of BRCA1/2 carriers or for young cancer patients, as the overall cancer risk appears low aside from breast cancer in young women.
Strawberry or red leopards are a rare colour morph of leopard () characterised by spot markings that are red or brown instead of black, thought to be a result of a mutation in the tyrosinase-related protein (TYRP1) gene. We report the first record of this phenotype on the African continent outside of South Africa, from Selous Game Reserve in southern Tanzania. One female leopard with strawberry colouration was documented out of 373 individual leopards (0.

For example, we know that brown centres are a major internal discolouration defect in macadamia nuts and are linked to the storage of nut-in-shell under improper conditions at high temperature and humidity. However, key chemical changes in brown centre kernels have not been described.

These alternatives are thought to be less bioaccumulative and, therefore, less toxic than legacy PFAS. Contaminant exposures occur concurrently with exposure to natural stressors, including the fungal pathogen ().
