One of the most concerning outcomes following surgery and anesthesia among older adults is a condition known as postoperative cognitive dysfunction (POCD). Often, patients and their family members report feeling very fearful that the patient will suffer permanent cognitive deficits after anesthesia. Unfortunately, this pre-emptive fear may contribute to the complex array of symptoms associated with POCD and further complicate the ability to fully understand the subjective experience of this postoperative complication.

About the study

The current study published in the British Journal of Anesthesia involved the collection of data from the comments section of the published article titled ‘The hidden long-term risks of surgery.’ The comments were given an alphanumeric code to maintain chronological order and structure, while the username, submission date, and time were kept anonymous.

To ensure your survival, your brain evolved to avoid one thing: uncertainty. As neuroscientist Beau Lotto points out, if your ancestors wondered for too long whether that noise was a predator or not, you wouldn’t be here right now. Our brains are geared to make fast assumptions, and questioning them in many cases quite literally equates to death. No wonder we’re so hardwired for confirmation bias. No wonder we’d rather stick to the status quo than risk the uncertainty of a better political model, a fairer financial system, or a healthier relationship pattern. But here’s the catch: as our brains evolved toward certainty, we simultaneously evolved away from creativity—that’s no coincidence; creativity starts with a question, with uncertainty, not with a cut and dried answer. To be creative, we have to unlearn millions of years of evolution. Creativity asks us to do that which is hardest: to question our assumptions, to doubt what we believe to be true. That is the only way to see differently. And if you think creativity is a chaotic and wild force, think again, says Beau Lotto. It just looks that way from the outside. The brain cannot make great leaps, it can only move linearly through mental possibilities. When a creative person forges a connection between two things that are, to your mind, so far apart, that’s a case of high-level logic. They have moved through steps that are invisible to you, perhaps because they are more open-minded and well-practiced in questioning their assumptions. Creativity, it seems, is another (highly sophisticated) form of logic. Beau Lotto is the author of Deviate: The Science of Seeing Differently.

A NASA-led research team used satellite imagery and artificial intelligence methods to map billions of discrete tree crowns down to a 50-cm scale. The images encompassed a large swath of arid northern Africa, from the Atlantic to the Red Sea. Allometric equations based on previous tree sampling allowed the researchers to convert imagery into estimates of tree wood, foliage, root size, and carbon sequestration.

The new NASA estimation, published in the journal Nature, was surprisingly low. While the typical estimation of a region’s carbon stock might rely on counting small areas and extrapolating results upwards, the NASA demonstrated technique only counts the trees that are actually there, down to the individual tree. Jules Bayala and Meine van Noordwijk published a News & Views article in the same journal commenting on the NASA team’s work.

FULL AudioBook | GreatestAudioBooks | Science Fiction / Fantasy — Early victories by the USSR in a global nuclear war cause the United Nations government to retreat to the moon leaving behind troops and fierce autonomous robots called “Claws”, which reproduce and redesign themselves in unmanned subterranean factories. After six bloody years of conflict the Soviets call for an urgent conference and UN Major Joseph Hendricks sets out to meet them. Along the way he will discover what the Claws have been up to, and it isn’t good… — Second Variety was first published in the May 1953 edition of Space Science Fiction Magazine. (Summary by Gregg Margarite)

About the Author, Philip K. Dick:
Philip Kindred Dick (December 16, 1928 – March 2, 1982) was an American writer notable for publishing works of science fiction. Dick explored philosophical, social, and political themes in novels with plots dominated by monopolistic corporations, authoritarian governments, alternate universes, and altered states of consciousness. His work reflected his personal interest in metaphysics and theology, and often drew upon his life experiences in addressing the nature of reality, identity, drug abuse, schizophrenia, and transcendental experiences.
