Almost every cell in your body has the same DNA sequence. So how come a heart cell is different from a brain cell? Cells use their DNA code in different ways, depending on their jobs. Just like orchestras can perform one piece of music in many different ways. A cell’s combined set of changes in gene expression is called its epigenome. This week Nature publishes a slew of new data on the epigenomic landscape in lots of different cells. Learn how epigenomics works in this video.
He assumed it was simply a problem of science communication. So, to help remedy the situation, he began giving public lectures on the looming dangers of climate change, and what it could mean for the sustainability of life on this planet. The results weren’t what he expected.
“The audiences would understand it on an intellectual level,” says Davies. “The science is pretty self-explanatory and very compelling.” But they didn’t seem to personally connect with the information. They understood it, but they weren’t feeling it, he says — and weren’t taking any action.
The real question is… can it draw Olaf from Frozen?? After all he loves summer!
Conceived by Disney Research and working in partnership with a student team at ETH Zürich, the Beachbot is a mobile robot that can turn an ordinary beach into an artist’s canvas. Thanks to innovative balloon wheels, the robot is able to traverse sandy beaches without leaving any noticeable tracks. Drawing is achieved using a controllable rake at the rear of the robot, with individually controllable pins that can be raised and lowered to create thick or thin lines in the sand. The drawing area on the beach is defined simply using four vertical poles that define the corners of the desired sand canvas. The Beachbot can then determine its position on the canvas to a high degree of accuracy using depth sensing and IMU (inertial measurement unit) technology. Artwork can be pre-programmed as the robot can draw lines or create block-filled areas. Alternately manual remote can be used to turn a beach into a live sketchpad. Beachbot is just one of Disney Research’s projects in the area of mobile robotics, including work on path-planning, robot choreography, localization, and human-robot interaction.
Recently, the Smithsonian stopped by the White House to take a 3D portrait of President Obama, in what will be be the highest resolution digital model of a head of state. Take a look at the process, and the 3D rendering created from this technology.
It was a tight race among this year’s 21 Ph.D. dance submissions. The previous winners of the contest scored each of them on their scientific and artistic merits, and these 12 finalists made the cut. Now it’s a dance-off between the sciences, including a tango based on robot collision avoidance, an acrobatic spectacle based on soil ecology, and, in one of the most meta Ph.D. dances ever, a hip-hop dance about the anthropology of hip-hop.
Featuring a collection of 10 unique prints, the exhibition is an illustrative autobiography of Dr Dufton’s research over the last five years.
Inspired by the works of Salvador Dali and psychedelic music posters from the 1960s, Dr Dufton’s work blends lively, surreal images with concepts from his scientific research. The artwork draws on various controversial topics, such as animal research and stem cell therapy, as well as portraying scientific techniques, equipment and processes. Through his art, Dr Dufton hopes to open up the scientific debate to the wider public.
