Why suicide is falling around the world, and how to bring it down more

Posted by in categories: biotech/medical, health

For a few people—those who are terminally ill, in severe pain and determined to die—suicide may be the least terrible option. In such circumstances, and with firm safeguards, doctors should be allowed to assist. But many of the 800,000 people who kill themselves each year act in haste, and more could be saved with better health services, labour-market policies and curbs on booze, guns, pesticide and pills. America, in particular, could spare much pain by learning from the progress elsewhere.

Urbanisation, fewer forced marriages and more curbs on the means of self-destruction.

Sluggish Brain Waves May Be Early Sign of Dementia

Posted by in categories: biotech/medical, neuroscience

Tracking brain wave activity in individuals at high risk for Alzheimer’s disease may be a promising new method for early detection, according to a new Canadian study by researchers at Baycrest Centre for Geriatric Care in Toronto, Ontario.

This is possible because brain waves tend to slow down in certain regions likely to be affected by the disease next, even before neurons have been lost.

The findings, published online in the journal Human Brain Mapping, show that individuals potentially in the early stages of Alzheimer’s disease (mild cognitive impairment) and those with a rare form of language dementia (primary progressive aphasia) exhibited sluggish brainwaves and subtle signs of damage in the brain regions responsible for memory and planning.

Elon Musk says there’s a 70% chance he’s going to move to Mars

Posted by in categories: climatology, Elon Musk, engineering, habitats, space travel

Elon Musk wants humans to make it to Mars. With his company SpaceX at his back, he’s pushed forward with some incredibly bold claims about what is possible for mankind on the Red Planet. He’s shown off concepts for Mars settlements and even called out scientists who say climate engineering on the planet is impossible.

Now, in an interview with HBO’s Axios, Musk doubles down on one of the more off-the-wall claims he’s made during his years in the spotlight. Mars, he says, will be his eventual home, and he estimates his odds of moving to the planet at a generous 70%.

People can sustainably share resources, under some conditions

Posted by in category: futurism

That’s why freedom of movement is one of the key conditions necessary to successfully share resources. Other necessary conditions include low population densities, low market value of the resources, variability in resource distribution and an ethos of sharing.

Sometimes, there is no “tragedy” in the tragedy of the commons, according to a new analysis that challenges a widely accepted theory.

Scientists have long believed that when there is to a shared resource, people will inevitably overuse it, leading to ruin for everyone—an idea known as the “ of the commons.”
