How operational research-driven differentiated TB care initiative helped reduce TB deaths in Tamil Nadu

Tamil Nadu’s differentiated TB care initiative — Tamil Nadu Kasanoi Erappila Thittam (TN-KET) or TB death-free initiative — was launched for the first time in India in April 2022 to reduce TB deaths. In just six months after launch, early deaths reduced by 20% and overall deaths reduced by 10% at the State level; in 2024, over two-thirds of the districts documented at least 20-30% reduction in TB death rate. The reason: the novel initiative is driven by operational research

Miyawaki forests in urban India are effective for carbon sequestration

While the criticism about high tree density per sq. metre in Miyawaki forests is partly valid, the vertical growth due to high density is not inherently unnatural or detrimental, but rather mirrors early-stage dynamics of natural forest regeneration, and may even enhance carbon sequestration and canopy formation in the short term

Can viral infections lead on to cancer recurrence?

A study suggests that a viral infection such as influenza and SARS/CoV-2 can set off an inflammatory cascade that “wakes up” the sleeping cancer cells located in distant organs such as lungs and bone marrow, leading them to proliferate

No State showed net increase in forest cover between 2015 and 2019

While the loss was in the forest core and bridge areas (corridors connecting different core areas), the increase in forest area was mostly restricted to islets — patches of forest containing no core and representing isolated habitats. Nearly half of newly added forests were islets, while a negligible 6% increase in forest cover was in the core
