20 Minute Contact with Nature Reduces Stress Hormone Cortisol






The data revealed that just a twenty-minute nature experience was enough to significantly reduce cortisol levels. But if you spent a little more time immersed in a nature experience, 20 to 30 minutes sitting or walking, cortisol levels dropped at their greatest rate. After that, additional de-stressing benefits continue to add up but at a slower rate. The image is in the public domain.

2,000 Atoms Exist in Two Places at Once in Unprecedented Quantum Experiment

The new experiment demonstrated a bizarre quantum effect from the double-slit experiment at an unprecedented scale.

Giant molecules can be in two places at once, thanks to quantum physics.

That’s something that scientists have long known is theoretically true based on a few facts: Every particle or group of particles in the universe is also a wave — even large particles, even bacteria, even human beings, even planets and stars. And waves occupy multiple places in space at once. So any chunk of matter can also occupy two places at once. Physicists call this phenomenon “quantum superposition,” and for decades, they have demonstrated it using small particles.

But in recent years, physicists have scaled up their experiments, demonstrating quantum superposition using larger and larger particles. Now, in a paper published Sept. 23 in the journal Nature Physics, an international team of researchers has caused molecule made up of up to 2,000 atoms to occupy two places at the same time.

Novo estudo questiona: será que devemos substituir antidepressivos por exercícios físicos?








Um novo estudo sugere que os exercícios físicos são tão eficazes em aliviar os sintomas de problemas de saúde mental e transtornos de humor, como ansiedade, depressão e esquizofrenia, quanto os medicamentos tradicionais. Se confirmada, essa pode ser uma excelente notícia para pacientes que sofrem com este tipo de problema, uma vez que isso pode significar menos tempo em instalações psiquiátrica e menos probabilidade de dependência de medicamentos psicotrópicos.
