Citizen scientists have documented over 160 sea slug species across habitats extending from northern mangroves to southern coral reefs. Dedicated trackers find these shell-less creatures, some no larger than a jelly bean, by identifying their preferred food sources. Their ongoing work submits vital field records to the Lee Kong Chian Natural History Museum, establishing baseline data as major coastal developments loom.

Off the busy coast of Pulau Hantu, one of Singapore’s southern islands, exists a tiny marine slug that resembles a cluster of iced doughnuts.
The doughnut doto (Doto greenamyeri), as it is known, is one of more than 160 species of sea slugs that have been recorded in Singapore’s waters.
They can be found in a wide range of marine habitats around Singapore’s islands, from coral reefs in the waters south of the country to the mangroves in Kranji.
Not all of them have been formally inducted into Singapore’s halls of science and many are still considered undescribed species.
These sea slugs can be as small as a jelly bean, and the process of searching for and finding these gem-like creatures has fascinated marine enthusiasts.
Their vibrant colours and slow movements also make them a favourite for scuba divers looking for an easy subject to photograph.
The doughnut doto, for instance, is so alluring that divers have travelled the world for a chance to spot it.

Facing systemic discrimination and repeated corporate rejections despite holding advanced degrees, Riyana Suree turned her personal hardships into community support across Tamil Nadu. Through her Thiru Aval Trust, the 36-year-old activist provides vital shelter, academic sponsorships, and sustainable career guidance to marginalized transgender individuals. Her journey from low-wage outreach work to national advocacy highlights the transformative impact of grassroots empowerment.
Scientific interest is turning toward the skeletal system as an active contributor to longevity rather than just a structural framework. Initial indications suggest that certain biological factors originating from skeletal tissue could influence how organisms age. A full understanding of the underlying physiological impact remains limited due to scarce initial data.
Researchers analyzing the universe's accelerating growth have identified structural instabilities within the prevailing cosmological model that could eliminate the requirement for hypothetical forces. By applying combined principles of general relativity and fluid dynamics, the analysis reveals that small cosmic disturbances naturally generate acceleration on their own. This mathematical framework challenges long-held assumptions regarding cosmic mechanics and offers a simpler explanation grounded entirely in stan…
