Global warming hit 1.37°C in 2025, with Earth accumulating heat at an accelerating rate
Global warming reached 1.37°C above pre-industrial levels in 2025, with the 1.5°C threshold now projected to be crossed within four years, according to the latest Indicators of Global Climate Change report. The findings carry particular alarm not just for current temperatures but for the accelerating rate at which heat is building across Earth's entire climate system — a signal of intensified warming to come. Scientists warn this accumulation dynamic points to future conditions more severe than the headline temperature figure alone suggests.

Scientists propose a radical new theory for how life began on Earth
Mineral nanoparticles may hold the answer to one of science's oldest questions: how did life actually begin? Researchers propose that these microscopic structures acted as primitive catalysts, driving the chemical reactions needed to assemble life's earliest building blocks without any biological machinery in place. If confirmed, the theory could reshape our understanding of life's origins — and where else in the universe it might emerge.

Scientists shut down cancer DNA repair to overcome drug resistance
Cancer cells frequently evade treatment by repairing the very DNA damage that drugs are designed to inflict. A compound called UNI418 disrupts this repair mechanism, stripping cancer cells of a key survival advantage. Paired with a PARP inhibitor, it restored drug sensitivity in resistant cells — offering a promising new approach to one of oncology's most persistent problems.

Novel nanowire device offers rapid, noninvasive cancer detection
Researchers in Japan have engineered a cancer detection device using zinc oxide nanowires capable of selectively capturing extracellular vesicles from bodily fluids — biological markers closely linked to tumor activity. The technology offers a faster, noninvasive alternative to traditional biopsies, potentially transforming how early-stage cancers are identified. If validated at scale, it could significantly lower the barrier to routine cancer screening.
