David Attenborough Netflix documentary: Australian scientists break down in tears over climate crisis One of Australia’s leading coral reef scientists is seen breaking down in tears at the decline of the Great Barrier Reef during a new Sir David Attenborough documentary to be released globally on Friday evening. Prof Terry Hughes is recounting three coral bleaching monitoring missions in 2016, 2017 and 2020 when he says: “It’s a job I hoped I would never have to do because it’s actually very confronting …” before tears cut him short. The emotional scene comes during the new Netflix documentary, Breaking Boundaries: The Science of Our Planet, and shows the toll the demise of the planet’s natural places is having on some of the people who study them.

Cell kinetics of auxin transport and activity in Arabidopsis root growth and skewing Auxin production in certain cell types significantly affects root growth To understand how localized auxin production affects auxin movement and activity, we generated constructs that express YUC1 and TAA1 under the control of several different cell-type-specific inducible (estradiol) promoters and introduced them into plants expressing the auxin reporter DR5:VENUS27,28 (Fig. 1a, b). Simultaneous expression of YUC1 and TAA1 results in IAA synthesis from tryptophan12,14,15. Expression of GFP driven by each promoter showed the expected expression patterns: pWER – epidermis, pSCR – endodermis, pSHR – stele, pAPL – phloem (protophloem, companion cells, and metaphloem sieve elements29), and pWOX5 - QC10,30 (Fig. 1d).

I grew up in an off-the-grid Christian commune. Here's what I know about America's religious beliefs The only time I saw Brother Sam in person, he was marching like a soldier as he preached, with sweat running like tears from his temples and the Bible a heavy brick in his right hand. It was 1978, I was five, and my family had traveled to Lubbock, Texas, for a Body Convention, which was what we called the semi-annual gatherings of hundreds, sometimes thousands, of members of The Body, or Body of Christ, an expansive network of charismatic communities created almost singlehandedly by Brother Sam. My family lived on a Body Farm, a mostly off-grid outpost on the northern shore of Lake Superior, where I grew up singing, clapping, hollering and dancing in the Tabernacle aisles as shamelessly as King David.

A pioneering study: Plant roots act like a drill In an interdisciplinary research project carried out at Tel Aviv University, researchers from the School of Plant Sciences affiliated with the George S. Wise Faculty of Life Sciences collaborated with their colleagues from the Sackler Faculty of Medicine in order to study the course of plant root growth. The plant researchers were aided by a computational model constructed by cancer researchers studying cancer cells, which they adapted for use with plant root cells. The fascinating and groundbreaking findings: For the first time in the world, it has been demonstrated, at the resolution of a single cell, that the root grows with a screwing motion - just like a drill penetrating a wall. In the wake of this study, the cancer researchers conjecture that cancer cells, too, are assisted by a spiral motion in order to penetrate healthy tissue in the environment of the tumor, or to create metastases in various organs of the body. The research was led by Prof.

Pocket - Poor teeth click 2x I am bone of the bone of them that live in trailer homes. I grew up next to Tiffany ‘Pennsatucky’ Doggett, the hostile former drug addict from the prison TV drama Orange Is the New Black. I know her by her teeth. Pennsatucky – a scrappy slip of a woman menacing, beating and proselytising to fellow inmates – stole the show during the first season of the Netflix prison series. But amid an ensemble cast of similarly riveting, dangerous characters, it was her grey, jagged teeth that shocked viewers into repulsed fixation.

Plant Architecture and Its Evolutionary Implications Another interesting finding borne from these models is that there doesn't seem to be strong correlations between architecture and phylogeny. Although species within a specific genus often share similar architecture, there are plenty of exceptions. What's more, the same form can occur in unrelated species. For instance, Aubréville's model occurs in at least 19 different families. Similarly, the family Icacinaceae, which contains somewhere between 300 and 400 species, exhibits at least 7 of the different models. Can Religion Guide the Ethics of A.I.? “Alexa, are we humans special among other living things?” One sunny day last June, I sat before my computer screen and posed this question to an Amazon device 800 miles away, in the Seattle home of an artificial intelligence researcher named Shanen Boettcher. At first, Alexa spit out a default, avoidant answer: “Sorry, I’m not sure.” But after some cajoling from Mr.

Plant Point of View: Orchids This series is the exploration of plants that are notable for various reasons: e.g., by producing specialized metabolites, by illuminating evolution, by serving as genetic models, or by their contributions towards practical applications. Orchids The orchid family (Orchidaceae) is the second largest plant family, comprising nearly 1000 genera.

Woman Gets Shamed For Breastfeeding Son In Public, Thousands Of People Stand Up For Her It is not uncommon for a natural activity to be turned into a social taboo. In many ways, the female body is particularly laden with rules and regulations attempting to control our life experiences. Often we must oblige, or we are viewed as “divergent,” “rebellious,” or even “disobedient.” Well, one woman had just about enough of the breastfeeding shaming from both a specific woman, and society, so she decided to do something about it. Ashley Kaidel was enjoying a meal at a restaurant when her baby starting showing signs of hunger.

The Mesmerizing Microscopy of Trees: Otherworldly Images Revealing the Cellular Structure of Wood Specimens After a recent march in D.C., where I walked Walt Whitman’s love of democracy and his conviction that “America, if eligible at all to downfall and ruin, is eligible within herself, not without,” I set out to temper the tumult of the human world with an immersion in Whitman’s other great love — the natural world. Visiting the National Museum of Natural History’s Objects of Wonder exhibition, a splendid embodiment of Whitman’s admiration of the character of trees stopped me up short: a display of slides revealing the cellular structure of trees and shrubs seen under a microscope — stunning images that occupy the lacuna between art and science, resembling ancient tapestries and Klimt paintings and galactic constellations. The slides, photographed by The Smithsonian’s Stanley Yankowski, are drawn from the 4,637 specimens amassed by the prolific wood collector Archie F. HT Smithsonian Magazine

US Olympian Simone Biles' withdrawal from the team final reminds us that she's human On Tuesday, though, Biles "looked like she got lost" somewhere in the air, CNN sports analyst Christine Brennan said. She nearly landed on her knees and left the field of play close to tears. Minutes later, word came that Biles would not compete with the team. Her departure stunned the sports world and her many fans in the US who've seen her repeatedly make the most difficult moves in gymnastics look like standard playground stunts. Biles' talent and charisma has catapulted her to a pedestal so high and seemingly untouchable that any mistake is magnified, and it's all the more devastating -- to Biles and to her many fans -- when she falls.

The Seedy World of Plant Poaching In September 2012, two conservation officers with the Ontario Ministry of Natural Resources were waiting along a dirt road in rural south-central Ontario for the poachers to emerge from the forest. The summer before, officers patrolling the area had stumbled upon a poached patch of wild American ginseng after noticing shallow holes pockmarking the ground next to discarded plants torn of their roots. In some spots, though, the stems and leaves had been neatly tucked back into the soil as if to cover up the massacre. The plants were now the standing dead. Simone Biles and the Weight of Perfection Mentally, the past five years have been what she called “a long journey.” When the Olympics were postponed from 2020 because of the coronavirus pandemic, Biles curled up in a corner of the gym’s locker room and cried. She didn’t want to be associated with U.S.A. Gymnastics any longer than she had to. Cecile Landi — who is serving as her personal coach in Tokyo — coaxed Biles to take time off: go on vacation, look for a bigger house, get a hot tub, relax.
