‘Maintain Asian forest diversity to avoid climate change impact’

A team of international scientists found that Southeast Asian forests resisted 'savannisation' during the Last Glacial Maximum, maintaining a mosaic of diverse closed and open forest types. Maintaining forest diversity is key to preventing future 'savannisation' and protecting tropical rainforests in regions like South East Asia.

Anthrax lethal toxin and tumor necrosis factor-α synergize to induce mouse death

Researchers found that anthrax lethal toxin (LT) and tumor necrosis factor-alpha (TNF-α) synergize to induce mouse death, primarily through damage to intestinal epithelial cells. Both necroptosis and apoptosis pathways are involved in this process, which could lead to a new target for preventing anthrax-caused death.

A novel angle on type 1 diabetes: RNA editing disruption mimics early-stage disease with no involvement of virus

A recent study by the Hebrew University proposes a new etiology for early stages of type 1 diabetes, attributing it to disrupted RNA editing within pancreatic beta cells. This perspective challenges long-held beliefs about viral involvement, suggesting potential implications for treatments and cures.
