Billions of years ago, Venus may have harbored life-giving habitats similar to those on the early Earth. Today, Earth's twin is a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists are now unveiling daring new strategies to search for clues from a time when the planet was alive.
Employing methods of direct cinema–observation, limited stylization, and non-intervention–this stark look into the State Prison for the Criminally Insane in Bridgewater, Massachusetts shows its denizens, who were often kept in barren cells and infrequently bathed, forced to strip naked publicly, force feeding, and the indifference and bullying by many of the hospital's staff.
The Grand Canyon is a breathtaking natural monument. It's one of the planet’s best-known landscapes, yet we often forget that it tells two billion years of the Earth's history. Geologists Karl Karlström and Laurie Crossey are the leading experts on this. Over the course of 8 days, they descend the Colorado river and tackle hundreds of rapids to unveil the mysteries held in the Grand Canyon, and the place that humans occupy within it.
On Easter Sunday 2012 the UK's Channel 4 showed a programme entitled Crucifixion in which Gunther von Hagens created his interpretation of the crucifixion of Jesus. The documentary examined the enduring iconic image of the Crucifix. A number of donors were used for the plastination of blood vessels to create the main structure of the body. At the end of the programme von Hagens announced that he did not expect to see the final work of art due to his ill health.
From the far north of Canada to the southern tip of Chile, through the southern United States, central Mexico and the Brazilian Mato Grosso, new concordant but still controversial archaeological discoveries have brought a new paradigm to the archaeology of American prehistory: the appearance of the first humans on the continent could date back to nearly 30,000 years before our era, that is to say, about 15,000 years earlier than the commonly accepted and taught thesis. Although there were a few mavericks in the past who disputed the scenario according to which the first ancestors of Americans arrived on foot through the Bering Strait 16,000 years ago, they were long kept out of the scientific community.
Black holes stand at the limit of what we can know. To explore that edge of knowledge, the Event Horizon Telescope links observatories across the world to simulate an earth-sized instrument. With this tool the team pursues the first-ever picture of a black hole, resulting in an image seen by billions of people in April 2019. Meanwhile, Hawking and his team attack the black hole paradox at the heart of theoretical physics—Do predictive laws still function, even in these massive distortions of space and time? Weaving them together is a third strand, philosophical and exploratory using expressive animation. “Edge” is about practicing science at the highest level, a film where observation, theory, and philosophy combine to grasp these most mysterious objects.
They have no roots, no seeds, no flowers, but mosses show immense survival capacities and can suspend their biological activity for long periods. Today, researchers are exploring the exceptional resistance of these archaic organisms. British ecologists have even resurrected a "zombie" moss that has been trapped in the permafrost for 1,500 years. Associated with decay and disliked in Europe, mosses are deified in Japan. With 25,000 species worldwide, bryophytes - their scientific name - are the seat of real ecosystems, and can develop in inhospitable landscapes, through an extravagant reproduction cycle.
The daughters of Title IX discover that pervasive gender-based stereotypes and discrimination persist within the high stakes professional world of surgery - a workplace designed for and and still controlled by men. Since 2003, half of medical students in the US have been women. Women remain in the minority in most surgical fields but their proportion is increasing. Leadership and culture in surgery remain disproportionately and persistently male despite ample evidence that women are just as good (and possibly better) at delivering care. Systemic barriers to success for women surgeons must be confronted and addressed for the surgical workforce to stay healthy and for patients to stay safe. We’ve interviewed dozens of surgeons who are women about their experiences, hopes, dreams and careers. This is a group of extraordinarily dedicated physicians who work every day to improve the health and lives of others despite untold challenges.
