A team of scientists from the Earth Commission has assessed the planet's health against eight key thresholds needed to protect life on Earth and found that human activities have led to seven of the eight boundaries already being breached. The report, published in Nature, assessed each area against two thresholds: whether it remained "safe" and whether the levels could ensure justice between species, current and future generations, and between countries and communities. The scientists describe the eight boundaries as "hard limits." Despite the worrying findings, the scientists are keen to stress that it is not too late for Earth, and they hope their report will galvanize governments and companies to make changes.

Scientists from the Finnish Hub for Development and Validation of Integrated Approaches (FHAIVE) and Tampere University have discovered an ancestral epigenetic defense mechanism related to nanoparticle exposure that is shared across various species. The study sheds light on how various species respond to particulate matter in a similar manner and proposes a solution to the one-chemical-one-signature problem, currently limiting the use of toxicogenomic in chemical safety assessment. The study also uncovers an important link between understanding the basic defense mechanisms in living organisms and their immune functions, which may lead to crucial epidemiological implications.
