• Microplastics are falling from the sky and polluting forests

  Tiny plastic particles aren’t just choking oceans and cities—they’re quietly infiltrating forests too. Scientists discovered that most microplastics arrive through the air, settling onto treetops before being washed or dropped to the forest floor in rain and falling leaves. Once there, natural processes like leaf decay help bury and store these particles deep in the soil. The findings reveal forests as hidden reservoirs of airborne pollution—and potentially a new frontline in the growing microplastics crisis.

• Most people get food’s environmental impact completely wrong, study finds

  People often get the environmental impact of food wrong, according to new research. While many assume processed foods are the worst, they tend to overlook the surprisingly high impact of items like nuts and underestimate how damaging beef really is. These misunderstandings come from relying on simple categories like “animal vs. plant” rather than the full picture.

• This 67,800-year-old handprint is the oldest art ever found

  Researchers have uncovered the world’s oldest known cave art—a 67,800-year-old hand stencil in Indonesia. The unusual, claw-like design hints at early symbolic thinking and possibly spiritual beliefs. This discovery also strengthens the case that humans reached Australia at least 65,000 years ago. It offers rare insight into the creative lives of some of our earliest ancestors.

• Why mosquitoes always find you and how they decide to attack

  Scientists have finally cracked how mosquitoes decide where to fly—and it’s not by following each other. Instead, each insect independently reacts to visual cues and carbon dioxide, zeroing in on humans when both signals align. Dark colors and CO2 together create the strongest attraction, triggering swarming and biting behavior. This insight could reshape how we design traps and prevent mosquito-borne diseases.

• Beavers are turning rivers into powerful carbon sinks

  Beavers may be unlikely climate heroes, but new research suggests they could play a powerful role in fighting climate change. By building dams and transforming streams into wetlands, these industrious animals dramatically reshape how carbon moves and is stored in landscapes. Over just 13 years, a beaver-engineered wetland in Switzerland stored over a thousand tonnes of carbon—up to ten times more than similar areas without beavers.
