Octopus suckers don’t just feel — they sense microbiomes. Distinct microbes on eggs, prey and other objects trigger chemotactile receptors, prompting reflexive movements in the suckers and arms.

Scientists say these microbial cues help guide key survival behaviors.
Octopuses use their arms to sense and respond to microbiomes on the seafloor
From the beginning of life on Earth, microbes, small but influential single-celled organisms, have shaped the environment that animals must adapt to in order to survive. Distinct microbial…

We can't recycle out of the problem.
Most plastics are hard to recycle or have no viable market after recycling.

This doesn’t mean we shouldn’t have tried, it’s just that even success required overshoot (ie, missing the target). And because it’s been framed as a “game over” threshold, media coverage of 1.5 has contributed to the idea that climate action is now pointless. That is not, and will never, be true.

The thing is, 1.5 degrees was was an unrealistic target from the start. The only way earth system models could make it work was by overshooting the target, getting to 0 emissions, and then devoting 2-3x the land area of India to carbon removal later in the century. We’d already warmed 1.2 degrees C.
Humanity has failed to limit global heating to 1.5C and must change course immediately, the secretary general of the UN has warned. 🔗👉 www.theguardian.com/environment/...

Scientists in Japan made a plastic that dissolves in seawater within hours and biodegrades in dirt in 10 days.

It’s made from food additives, releases nutrients like plant vitamins, and doesn’t leave behind any nasty microplastics.😎👏💙

Most plastic items are too small for recyclers to bother sorting and processing, or they're assembled in such a way that it's less expensive to just make new plastic.

In fact, only 5% of Americans’ plastic finds new life.
