An international annual climate assessment reports a record gap between energy entering and leaving Earth, with about 90% of excess heat absorbed by the oceans. The authors link this build-up to accelerating sea-level rise and more marine heatwaves, while noting that the faster-than-expected increase is still being investigated.
UCL researchers found that regulatory T cells accumulated before lung tumours developed, while prototype blood tests tracked the signal and targeted drugs reduced tumour formation in mice. The intervention evidence is preclinical and the blood test is not yet a validated screening tool.
A longitudinal analysis of 87,857 UK residents from 2009 to 2024 found psychological distress rose after major political, economic and public-health shocks and often persisted, with young adults and disadvantaged groups most affected. The quasi-experimental study cannot exclude every concurrent influence and did not test positive national events.
Researchers recorded more than 90 hours of behaviour in two South African parks and identified over 40 intentional gesture types. Elephants monitored recipients, changed signals and persisted when ignored. The observations focused on competitive encounters in two populations, so other contexts and populations still need study.
Single-cell mitochondrial DNA sequencing of vulnerable post-mortem brainstem neurons found extensive deletions alongside higher PINK1 expression, especially in people who survived longer after diagnosis. The association suggests a protective quality-control response but does not show that increasing PINK1 will slow disease.
Analysis of primary-care records for 1.4 million women in England linked several pregnancy complications and postnatal depression with later cardiovascular, metabolic and kidney conditions. The large observational study identifies associations and cannot establish that the complications caused the later disease.
