As global temperatures rise, disease-carrying mosquitoes are steadily expanding into new regions once thought too cold for them to survive. Scientists have documented the northward spread of species such as Aedes aegypti and Aedes albopictus, which can transmit dengue, Zika, and chikungunya. According to the Centers for Disease Control and Prevention, this shift increases the risk of outbreaks in areas with little prior exposure. While the overall threat varies by region, experts warn that climate change is reshaping where mosquitoes live—and who may now be at risk.

Scientists are beginning to explore what some describe as a “third state” that exists between life and death, where cells remain active even after the body has stopped functioning. Research has shown that certain genes and cellular processes continue for hours, or even days, after death. Some experts suggest this liminal phase could hold clues about consciousness and how life is defined at the cellular level. While highly debated, these findings challenge traditional views of where life ends—and hint at mysteries science is only beginning to uncover.

It may sound tropical and harmless, but the “Pineapple Express” is anything but lighthearted. This atmospheric river channels huge amounts of moisture from near Hawaii all the way to the U.S. West Coast, where it can unleash days of relentless rain and heavy snow. According to the National Weather Service, these events can trigger flash floods, landslides, and widespread damage when conditions align. While the phenomenon is natural, a warming climate is expected to intensify its impacts, making the Pineapple Express a storm pipeline worth watching closely.
