It found that guidelines and decentralized services were common, but access to testing, affordable medicines and treatment in harm-reduction settings remained uneven. The survey describes health-system practices; it did not measure treatment outcomes in individual patients.

A Mexican shrub can fertilize itself when dry-season pollinators are scarce

The dry-season shrub Wigandia urens can produce seeds through autonomous self-pollination when pollinators are less active. Researchers found that animal pollinators still contributed substantially to seed production, giving the plant both reproductive backup and opportunities for cross-pollination.

Local trust is tied more to results than formal rules, review finds

A systematic review of 18 quantitative studies found that responsiveness was the governance practice most consistently associated with public trust in local governments.

Review compares first treatments for a rare lymphoma, with mixed results

Researchers combined results from seven randomized trials involving 1,334 people with previously untreated peripheral T-cell lymphoma, a rare blood cancer. The analysis found that some regimens produced higher response or disease-control rates than CHOP, but it found no significant differences in overall survival or progression-free survival. Risks of particular blood-related side effects varied among regimens.
