These 3D images are our first ever look at how DNA shapes itself inside cells. For the first time, scientists have been able to model the physical structure of mammalian genomes from individual cells, giving us a unique 3D perspective on how DNA packages itself inside our cells.
Through the new technique, scientists can see how the arrangement of cell chromosomes (DNA strands) are designed to keep some cells active or inactive at any one time. The procedure, which so far has been conducted on mice cells, could help us understand more about how animals grow, as well as how cell malfunction can lead to disease. "Knowing where all the genes and control elements are at a given moment will help us understand the molecular mechanisms that control and maintain their expression," says one of the researchers, Ernest Laue from the University of Cambridge in the UK. Watch Spring Turn Into Summer, One Picture at a Time. The Power of Looking Closely. At least in the US, it’s the start of a long holiday weekend, and elsewhere there are things like the Euros and Brexit to distract people from the internet, alas.
I wanted to share this video by Amy Herman on “Visual Intelligence,” based on her book Visual Intelligence: Sharpen Your Perception, Change Your Life, which in turn was based on a project she used to do at the Frick Collection while she was training medical students how to look at art. The reason I like it is that the single favorite aspect of my son’s education to this point (he starts high school in the fall) is exactly what Herman describes: During his first two years of elementary school, his classmates would sit and look at works of art, describe objectively what they see, and then reason from what they saw.
Even though the program was discontinued (public schools, budget cuts, “that’s not on the Common Core”) it was massively influential on him, especially since he gets dragged to museums everywhere. Growing a 1,223 pound pumpkin from seed to scale in time lapse. Glowing, blooming fungi in time lapse – Planet Earth II Fungi, unlike plants, thrive in the darkness of the forest floor.

Hungry Trees. Introductory plant biology video lecture series. Have you been looking for high-quality, university-level introductory plant biology videos?
There are not many available on topics other than photosynthesis and pollination. The University of California at Berkeley publishes videos from many of its course lectures on YouTube. One course of interest to plant biologists is the Introduction to Biology (Bio 1B) course. The full course is in three parts and covers plant biology, as well as evolution and ecology – a playlist of all 43 recorded lectures is here.
The plant biology lectures feature Professor Lewis Feldman, who has won several awards for teaching excellence. Plantastic! Nature Video Lindau collection. Objectivity: Royal Society Videos. Deep Look. The Best of ScienceTake. We posted our 100th ScienceTake video, on cockroaches and robots, this week.
Since September 2013, ScienceTake videos of apes, bats, water droplets, lassos, popcorn and spider sex have been viewed millions of times. With each ScienceTake, we try to offer compelling (and sometimes creepy) imagery, a glimpse at how science is done and answers to questions that are rarely asked. Self made shape. London's Screen Archives: Kew Herbarium. Animated Life: Coelacanth. Exploding Cucumbers! - Slo Mo #36 - Earth Unplugged. Has Botany got its poster boy? At Plant Science Today Mary Williams is looking forward to the release of The Martian, a film that could have a major effect on the perception of botany.
She notes that it has two major features, botanist as the hero – and the botanical work is a key element of the film. This film provides a rare opportunity for the plant science community to leverage pop culture in order to highlight the importance of the work we do. There is a precedent for this. Archaeology had a big increase in student numbers following the release of Raiders of the Lost Ark. Physics has had an increase in student numbers after The Big Bang Theory made physicists seem likeable. Likeability is often overlooked, but I think it’s crucial.
Plant scientists in contrast have a different image. It would be peculiar if the constant drip of negative role models in popular culture didn’t have an effect on recruitment, so Matt Damon as a botanist is valuable simply as a positive anchor for botany.

Review: ‘The Creeping Garden,’ on the Wonders of the Slime Mold. Photo Tim Grabham and Jasper Sharp’s uncanny documentary “The Creeping Garden” has a way of growing on you.
It begins as an unhurried look at an outlandish organism that’s neither fish nor fowl nor fungus: the slime mold, which resembles an extraterrestrial colony of polyps and appears here in pulsating, wide-screen sports-car-yellow close-ups.
