Dragon’s solar arrays have deployed and the spacecraft is safely in orbit following a launch on the SpaceX Falcon 9 rocket at 6:01 p.m. EDT from Cape Canaveral Air Force Station in Florida, carrying more than 5,000 pounds of research, hardware and supplies to the International Space Station. Dragon is scheduled to arrive at the orbiting laboratory Saturday, July 27. Details: https://go.nasa.gov/2GwcjjF

Though some computer engineers claim to know what human consciousness is, many neuroscientists say that we’re nowhere close to understanding what it is — or its source.

In this video, bestselling author Douglas Rushkoff gives the “transhumanist myth” — the belief that A.I. will replace humans — a reality check. Is it hubristic to upload people’s minds to silicon chips, or re-create their consciousness with algorithms, when we still know so little about what it means to be human?

You can read more about Rushkoff’s perspective on this issue in his new book, Team Human.

The thing that Carl Sagan did better than anybody else was connecting to the science through emotion and stories, says NASA’s Michelle Thaller. Watching him when growing up formed Thaller’s vision of what an astronomer could be and inspired her for the rest of her life.

Restless rapid eye movement (REM) sleep impedes emotional processing, which may contribute to mood and anxiety disorders, new research suggests.

A team of Dutch investigators used fMRI to scan the brains of participants who underwent a stressful experience — in this case, hearing themselves sing out of tune. Brain activity was measured using electroencephalography (EEG).

The next morning, after spending the night in a sleep laboratory, participants were subjected to the same unpleasant experience. Those who had experienced REM sleep were less distressed, whereas those with restless REM sleep were once again upset.

CANCER patients with previously incurable tumours have been given hope by a life-extending treatment which can double the length of time a person can live cancer-free.

The new worldwide medical trial involving the Beatson Cancer Centre in Glasgow has discovered a high-precision radiation treatment which can extend a patient’s lifespan by more than a year. Patients diagnosed with metastatic tumours – cancer which had spread to other parts of the body – were thought to be incurable, but researchers on the clinical trial have found that aggressive radiation therapy can increase life expectancy.

Hailing the research as a “game-changer”, scientists gave almost 100 cancer patients from Scotland, Canada, the Netherlands and Australia “substantially higher doses of radiation” to areas where their cancerous tumours had spread. Patients receiving the treatment, known as stereotactic ablative radiotherapy, lived 13 months longer on average.
