Sniffing out Parkinson's disease

A team of researchers discovered the chemicals responsible for the distinctive smell of Parkinson's disease using a 'super smeller'. The finding could lead to an early diagnosis and monitoring of the condition. Hippuric acid, eicosane, and octadecanal were identified as biomarkers in sebum samples from patients with Parkinson's.

Solving the 'Catch 22' of rectal cancer

Researchers developed a non-invasive MRI methodology to determine if tumours have invaded lymph nodes prior to surgery. This innovation helps clinicians choose optimal treatment strategies and reduces overtreatment risks. By improving accuracy, SPI may also aid in selecting patients for pre-operative radiation and chemotherapy.

Better water testing, safer produce

Researchers compared two water testing methods to ensure safe irrigation water for leafy greens, finding excellent results when samples were clean. However, discrepancies arose when environmental factors like sediments and salts were introduced, highlighting the need for a user-friendly guide to ensure consistent accuracy.

North Africans were among the first to colonize the Canary Islands

A new study published in PLOS ONE found that people from North Africa were among the first to colonize the Canary Islands, arriving by 1000 CE. The researchers analyzed ancient mitochondrial genomes and identified lineages consistent with radiocarbon dating evidence, suggesting a complex and heterogeneous process of colonization.
