Between your ears lies a miracle of nature, with more connections than our galaxy has stars. In the past, the idea of mapping the connectome—or the interconnected neuronal pathways of the brain (the white matter), was thought impossible. Now, a group of scientists are planning to do just that. How? They plan on using an oncoming supercomputer with tremendous power. Should they be successful, it could stand as one of the greatest achievements in the history of science. And that’s just one of the project's scientists at Argonne National Laboratory are planning, with Aurora 21 (A21).

Healthy sex is good for the body and our psychology, too. It boosts the immune system, lowers blood pressure, improves sleep, and eases stress and anxiety, giving us an overwhelming sense of well-being. In today’s hectic world, it can be hard to find a suitable partner. This is truer for millennials. A 2016 study, published in the journal Archives of Sexual Behavior, finds a surprising fact about the latest adult generation: they’re having less sex than the two previous ones, baby boomers and Gen Xers.

We often think of spirituality as something wholly outside of science. Though they seem diametrically opposed, could there ever be a marriage between the two? Might not science inform spirituality and vice-versa? One problem is, there’s a great range of opinions on what exactly spirituality is. It also varies across cultures and has been interpreted differently at different times in history. Generally speaking, a spiritual experience is one that transcends the self and connects the person to the universe in a profound and meaningful way. This is separate from religion which often includes dogma, religious texts, and some sort of institution.

One in 14 people ages 65 and older develop Alzheimer’s. Experts say we are all at risk, although some of us are far more likely to develop it than others. Its origin is complex. The neurodegenerative disorder is thought to have both genetic and environmental components. New research shows that alcohol consumption is more weighty a cause than first thought, particularly heavy drinking on a consistent basis.
