Singapore scientists crack the genome of Singapore's national flower

The genome of Singapore's National Flower, Papilionanthe Miss Joaquim, has been decoded by a collaboration between A*STAR and SingHealth Duke-NUS Institute of Biodiversity Medicine. The study reveals the presence of natural products with antioxidant properties, flavonols, and anthocyanins, which could be used for healthcare purposes.

Morning blue light treatment improves sleep in patients with PTSD

Researchers at the University of Arizona Health Sciences found that morning blue light therapy improved sleep quality and reduced PTSD symptom severity in patients. The study's results suggest a potential non-invasive treatment approach for retaining benefits of therapy long after treatment ends.

Half of the data deficient species may be threatened with extinction

A recent study predicts that over half of lesser-known species are in danger of disappearing. The researchers used machine learning to calculate the risk of extinction for thousands of data-deficient species, finding that as many as 85% of amphibians and around half of mammals and reptiles face an uphill battle.
