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)

We now know that the Galaxy is full of potentially habitable planets. So why do we see no signs that any civilizations have come before us? Matt O’Dowd, astrophysicist and host of PBS Space Time, explains why Fermi’s paradox really is so surprising, and he offers a new piece of evidence that may point towards the solution.

Astrophysicist Matthew O’Dowd spends his time studying the universe, especially really far-away things like Quasars, super-massive black holes and evolving galaxies. He completed his Ph.D. at NASA´s Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. Currently he is a professor at the City University of New York´s Lehman College and an Associate at the American Museum of Natural Historys Hayden Planetarium.

This talk dives into four critical dimensions — social, economic, political, and military — to uncover the patterns that led to World War I and II. By comparing those pivotal moments with today’s global dynamics, it reveals troubling signs of growing instability. Are we on the brink of a Third World War? Through the lens of history, this analysis offers a powerful reflection on the present — and a warning to not repeat the mistakes of the past.

Heni Ozi Cukier, widely known as Professor HOC, is an expert in international politics dedicated to making geopolitics more accessible to the general public. He shares his extensive knowledge — and insights into the challenges and dynamics of the contemporary world — through what has become Brazil’s largest geopolitics YouTube channel: PROFESSOR HOC.

He is also behind award-winning documentaries, including Cracol ndia.

In the United States, he worked at the United Nations Security Council, the Organization of American States (OAS), and the Woodrow Wilson Center think tank.

In Brazil, he gained prominence as the founder and coordinator of the postgraduate program in Geopolitics at PUC Paraná, establishing himself as a leading voice in teaching international relations and analyzing global affairs.

He holds a degree in Philosophy and Political Science, and a Master’s in Conflict Resolution and International Peace from the renowned American University in Washington, DC. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Dark energy and dark matter are two placeholders for mysterious forces and substances that expand our universe and make up the majority of its matter, respectively. In a new theory, one physicist says that defects in spacetime explain both of these mysteries at the same time. Let’s take a look.

This video comes with a quiz which you can take here: https://quizwithit.com/start_thequiz/1748971420417x503138930832703500

Correction: I mixed up the gems, sorry. I should have said, defects change the colour of sapphires to red and green, not diamonds.

IN A NUTSHELL 🌞 Solar hydrogen generation could revolutionize clean energy by converting sunlight into hydrogen fuel. 💡 Researchers discovered that elevating electrolyte temperatures boosts bismuth-vanadate electrode activity by 40%. 🔍 The study provides new insights into how temperature affects solar water splitting and metal-oxide cell performance. 🚀 Advancements in this field may accelerate the

When placed under a powerful laser field (i.e., under strong-field ionization), electrons can temporarily cross the so-called quantum tunneling barrier, an energy barrier that they would typically be unable to overcome. This quantum mechanics phenomenon, known as quantum tunneling, has been the focus of numerous research studies.

Precisely measuring the exact time that an electron spends inside a barrier during strong-field ionization has so far proved challenging. In recent years, physicists have developed advanced experimental tools called attoclocks, which can measure the timing of ultrafast electron dynamics and could thus help to answer this long-standing research question.

Despite their potential for measuring the tunneling time of electrons, most attoclocks developed to date have had significant limitations and have been unable to yield reliable and conclusive measurements. In a recent paper published in Physical Review Letters, researchers at Wayne State University and Sorbonne University introduced a new attoclock technique that leverages the carrier-envelope phase (CEP), the offset between the peak of a laser’s pulse’s envelope and its oscillating field, to collect more precise tunneling time measurements.

Social engagement is a vital component of psychological and physical well-being linked to better health and a longer life, yet many older adults struggle to maintain relationships that support these outcomes.

New research from Nanyang Technological University in Singapore finds that changes in the brain’s intrinsic functional connectivity networks fully account for the decline in observed with aging.

Sociability is a trait encompassing communication effectiveness, emotional management, and social assertiveness, that tends to diminish with age. Older adults, particularly those who live alone, are at increased risk of isolation, limiting forms of social participation.
