mar 11 \ jeanne van heeswijk \ fields of interactions
Jeanne van Heeswijk (Bard College, Keith Haring Fellow in Art and Activism), is a visual artist who facilitates the creation of dynamic and diversified public spaces in order to “radicalize the local.” Van Heeswijk embeds herself as an active citizen in communities, often working for years at a time. These long-term projects, which have occurred in many different countries, transcend the traditional boundaries of art in duration, space and media and questions art’s autonomy by combining p

Are Flowers Smelling You Back?w
Animals utilize their sense of smell to explore their surroundings. But
what about plants? When you smell a flower, is it smelling you back? Is
it trying to figure out if your nose would make a good pollinator?
Chemical ecologist Consuelo De Moraes shows us a parasitic vine that
uses smell to find its preferred host—the tomato.  (02:48)

Usman Riaz and Preston Reed: A young guitarist meets his hero
Usman Riaz is a 21-year-old whiz at the percussive guitar, a style he learned to play by watching his heroes on YouTube. The TED Fellow plays onstage at TEDGlobal 2012 -- followed by a jawdropping solo from the master of percussive guitar, Preston Reed. And watch these two guitarists take on a very spur-of-the-moment improv.Preston Reed’s hands have an otherworldly coordination. The fingers, nails, thumbs, and palms of both left and right dance, pluck, strum, and slap his guitar, which bur

Excitonics

An exciton is an excitation that mediates the absorption and emission of light, especially in low-cost disordered solar cell and LED materials. In the Center for Excitonics, we seek to supersede traditional electronics with devices that use excitons to mediate the flow of energy. In my presentation, I’ll describe two applications of excitonics in devices: high-brightness quantum dot-based LEDs, and exciton fission in high efficiency solar cells.

8.2 Chromosome scaffolds

Most of the chromosomal DNA chains within the interphase nucleus are believed to be held on a scaffold or backbone structure made from various proteins, with loops of between 20 and 200 kb extruding from attachment sites. This chromosome structure is shown schematically in Figure 40. The scaffold, as well as permitting further compaction, serves to bring the DNA together in organised regions. There are many different protein components of these scaffolds, amongst them DNA topoisomerases.

Nucleosomal DNA packaging into a 30 nm fibre: the role of histone H1

When chromatin is isolated from the nucleus and examined under the electron microscope, it can be seen as a 30 nm fibre. This fibre is formed through the action of the histone H1 on the nucleosomal DNA in the 10 nm fibre. In contrast to the other histone proteins, H1 does not contain the histone fold motif.

Compaction of the 10 nm fibre to give the 30 nm fibre is achieved by interaction of the H1 protein with both the linker DNA and the histone octamers, as shown in Figure 31

The histone fold and formation of the nucleosome

We have seen how in the eubacterial chromosome, bending DNA serves to facilitate its compaction. A similar process occurs in eukaryotic cells in that DNA is bent and wrapped around a protein unit. In this case, the core unit is a protein–DNA complex termed a nucleosome. The nucleosome comprises the core histone proteins H2A, H2B, H3 and H4 arranged in a structure known as the core histone octamer, with an associated length of DNA. In order to understand how the nucleosome is a

2.6 Obesity and ageing

So, it seems that a part of the explanation for Ron's obesity, and the health problems that have led him to seek medical advice, may relate to the environment in which he is living, and more specifically the diet that he has chosen. It may also be a diet that is especially effective in activating the reward circuits in Ron's brain. However, Ron is also in his later middle age. A longitudinal study of people of this age in the USA suggests that average body weight increases by 1–2 kg per dec
