Wild baboons not capable of visual self-awareness when viewing their own reflection

Researchers at UCL conducted a study on wild Chacma baboons, finding they didn't recognize themselves in mirrors. The baboons showed curiosity with laser marks on visible body parts but not when the mark appeared in their mirror reflection. This strengthens evidence that monkeys do not recognize their own reflections.

War and climate crisis drive transformation of fertiliser industry

A team from the Research Institute for Sustainability finds that supply structure changes, geopolitical competition, and decarbonization drive fertiliser market shifts. To address these challenges, coordinated measures are needed, including promoting sustainable fertiliser management practices and reducing synthetic fertiliser use.

Enhancing patient activation: A controlled implementation study of an interprofessional evidence-based counseling program for complementary and integrative healthcare in cancer patients ('CCC-Integrativ')

A controlled implementation study found that an interprofessional evidence-based counseling program significantly enhanced patient activation among cancer patients. The program showed a positive effect on patient activation, with improved scores on the Patient Activation Measure questionnaire.

Anti-correlation between KLRG1 and PD-1 in tumor CD8 T cells

A new study published in Oncotarget discovered an anti-correlation between PD-1 and KLRG1 expression in human tumor infiltrating CD8 T cells. This finding suggests the potential for combination therapy to enhance cancer treatment by targeting both markers simultaneously, which could lead to more significant and long-lasting benefits.

Empty headed? Largest study of its kind proves ‘bird brain’ is a misnomer

Scientists discovered that dry museum skulls of long-dead birds can provide surprisingly detailed information on their brain structures. The study found a nearly 1:1 correlation between the brain's volume and digital imprints, allowing researchers to gather insight into elusive species without seeing their brains.

Effect of gamma-rays on recombination dynamics and defect concentration in a wide bandgap perovskite

A new study reveals that gamma-ray exposure can passivate some defects while activating others, leading to improved recombination dynamics. The concentration of dominant 0.5 eV defects decreases with increasing dose, while the diffusion coefficient increases by orders of magnitude.

Childhood poverty and/or parental mental illness may double teens’ risk of violence and police contact

Research from the UK Millennium Cohort Study finds that children exposed to poverty and family adversity are more likely to carry or use a weapon and get in trouble with the law by age 17. These factors account for nearly a third of teen weapon issues and over a quarter of police contact cases.
