As neuro-ophthalmology educators, we have sought ways to improve the teaching of pupil-related disorder, focusing on incorporating their dynamic aspects and active learning. Our solution is an app for smartphone and tablet devices. The app, Pupil Wizard, provides a digital textbook featuring a dynamic presentation of the key pupillary abnormalities. It allows the users to interact with a digital patient and explore how each condition responds to direct and indirect light stimuli, near focus, and changes in ambient light (Fig. 1). Moreover, the users can test their knowledge in quiz mode, where random pupillary abnormalities must be correctly identified and multiple-choice questions about them answered.

Deep in the swamps of the American Southeast stands a quiet giant: the bald cypress (Taxodium distichum). These majestic trees, with their knobby “knees” and towering trunks, are more than just swamp dwellers—they’re some of the oldest living organisms in Eastern North America. Some have been around for more than 2,500 years, quietly thriving in nutrient-poor, flooded forests where most other trees would wither.

But life isn’t easy for these ancient trees. They’re under siege from a variety of threats: rising seas, insect infestations, wildfires and increasingly erratic weather patterns. Unlike most animals, trees generally don’t die of old age—they succumb to the stresses around them.

A study by Florida Atlantic University, in collaboration with Lynn University, the University of Georgia, the Georgia Department of Natural Resources, and the Georgia Museum of Natural History, reveals how dramatic shifts in climate can have long-lasting effects on even the toughest, most iconic trees—and offers a glimpse into the powerful forces that shape our natural world.

I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors! 1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot). 2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse. 3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect. 4. I said that the Gödel Incompleteness Theorems implied that mathematics is made up by humans, but that is wrong, just ignore that statement. I have learned more about it now, here is a good video explaining it: • Gödel’s Incompleteness Theorem — Numberphile 5. In the animation about imaginary numbers I drew the real axis as vertical and the imaginary axis as horizontal which is opposite to the conventional way it is done.

As research continues, the term “bird brain” no longer carries a negative connotation. Avian researcher John Marzluff showcases a few amazing, problem solving (and sometimes vindictive) feats accomplished by crows in order to break down common misconceptions about avian intelligence.

John Marzluff, Ph.D., is the James W. Ridgeway Professor of Wildlife Science at the University of Washington. His research has been the focus of articles in the New York Times, National Geographic, Audubon, Boys Life, The Seattle Times, and National Wildlife. PBS’s NATURE featured his raven research in its production, “Ravens,” and his crow research in the film documentary, “A Murder of Crows”. His graduate and initial post-doctoral research focused on the social behavior and ecology of jays and ravens. He was especially interested in communication, social organization, and foraging behavior. His current research brings this behavioral approach to pressing conservation issues including raptor management, management of pest species, and assessment of nest predation.

His book, In the Company of Crows and Ravens (with Tony Angell, 2005 Yale U. Press) blends biology, conservation, and anthropology to suggest that human and crow cultures have co-evolved. This book won the 2006 Washington State Book Award for general nonfiction. With his wife, Colleen, he has published Dog Days, Raven Nights (2011 Yale University Press), which combines reflection with biology and the recreational pursuit of dog sledding to show how a life in science blooms. Gifts of the Crow (2012 Free Press) applies a neurobiological perspective to understand the amazing feats of corvids. He is a member of the board of editors for Acta Ornithologica, Landscape Ecology and Ecological Applications. Currently leader of the U.S. Fish and Wildlife Service’s Recovery Team for the critically endangered Mariana Crow, he is also a Fellow of the American Ornithologist’s Union.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Half of all habitable land on earth is now dedicated to supporting human activity. And as of the year 2020, the mass of all man-made materials now outweighs the mass of all life forms on earth.

Despite all this, we are still newcomers – untrained pilots steering an ancient, ever-changing planet. If we want to survive long-term and continue to grow, we will have to make bigger technological leaps than ever before.

This film explores the wildest, most ambitious, most dangerous ideas to keep Earth and humanity thriving, by protecting each of its layers – from the lithosphere to the stratosphere.

Many of our ideas may never materialize, but by dreaming them up, we can open our minds to the full potential of human willpower and intellect. The future is ours to build.

The brainwaves of people with neuropathic pain show a distinct pattern: more slow theta waves, fewer alpha waves, and more fast, high beta waves, co-lead author Sylvia Gustin, a clinical psychologist and UNSW professor, said in the statement. Her research has investigated changes in the thalamus—a central brain structure that relays sensory and motor signals to the cerebral cortex—associated with nerve pain.

The PainWaive system consists of an electroencephalogram (EEG) headset that records brain activity paired with an app that instructs patients on how to control their brainwaves through neurofeedback games, according to a UNSW statement. Four participants who suffer from corneal neuropathic pain—a condition that causes painful hypersensitivity of the eyes, face, or head—underwent 20 PainWaive sessions over the course of four weeks.

This study offers new hope for drug-free pain treatments, but further trials will need to verify its results.

The miracle of life. A 40-week process where you developed from a single cell to fully formed human baby. All within in your mother’s womb. Now, imagine you were born in an artifical womb. How would we benefit from artificial wombs? What would be the downsides?

Is artificial intelligence (AI) capable of suggesting appropriate behaviour in emotionally charged situations? A team from the University of Geneva (UNIGE) and the University of Bern (UniBE) put six generative AIs — including ChatGPT — to the test using emotional intelligence (EI) assessments typically designed for humans. The outcome: these AIs outperformed average human performance and were even able to generate new tests in record time. These findings open up new possibilities for AI in education, coaching, and conflict management. The study is published in Communications Psychology.
