Creative Thinking in both Science and the Arts Is Not for the Faint of Heart

Posted by in categories: media & arts, science

Both arts and sciences advance through open-minded iterations. The alternative of staying within traditional boundaries suppresses the exploration of new territories. As Oscar Wilde said: “Consistency is the last refuge of the unimaginative.”

Recognizing the crucial role that imagination plays in advancing both arts and sciences would translate to a culture that fosters innovation by rewarding creativity. Conventional groupthink could be circumvented by populating selection committees of funding agencies with creative individuals rather than with traditional thinkers. A culture of innovation would also benefit from overlap spaces where scientists and artists interact. In deriving his theory of gravity Albert Einstein was inspired by the philosopher Ernst Mach, and Einstein’s new notions of space and time inspired Picasso’s paintings.

Creativity in arts and sciences establishes a backdrop for human existence, as the content it invents gives pleasure and meaning to our lives. The human act of creation is an infinite-sum game, from which all of us benefit. And we can all participate in the creative process, as long as we follow Wilde’s advice: “Be yourself; everyone else is already taken.”

Ultra-thin lithium offers a solid platform for high-capacity batteries

Posted by in categories: energy, materials

Scientists in South Korea have made a breakthrough in battery research that could help us bust through a key bottleneck in energy storage. The team’s advance overcomes a technical issue that has held back highly promising lithium-metal battery architecture and could pave the way for batteries with as much as 10 times the capacity of today’s devices.

The reason lithium-metal batteries hold so much promise is because of the excellent energy density of pure lithium metal. Scientists hope to swap out the graphite used for the anode in today’s lithium batteries for this “dream material,” though this comes with some complicated problems to solve.

One of the key issues relates to needle-like structures called dendrites, which form on the anode surface as the battery is charged. These penetrate the barrier between the anode and the battery’s other electrode, the cathode, and quickly cause the battery to short-circuit, fail, or even catch fire.

Google and Harvard map brain connections in unprecedented detail

Posted by in categories: information science, mapping, robotics/AI

The researchers started with a sample taken from the temporal lobe of a human cerebral cortex, measuring just 1 mm3. This was stained for visual clarity, coated in resin to preserve it, and then cut into about 5300 slices each about 30 nanometers (nm) thick. These were then imaged using a scanning electron microscope, with a resolution down to 4 nm. That created 225 million two-dimensional images, which were then stitched back together into one 3D volume.

Machine learning algorithms scanned the sample to identify the different cells and structures within. After a few passes by different automated systems, human eyes “proofread” some of the cells to ensure the algorithms were correctly identifying them.

A Massive New Gene Editing Project Is Out to Crush Alzheimer’s

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

The idea is simple: decades of research have found certain genes that seem to increase the chance of Alzheimer’s and other dementias. The numbers range over hundreds. Figuring out how each connects or influences another—if at all—takes years of research in individual labs. What if scientists unite, tap into a shared resource, and collectively solve the case of why Alzheimer’s occurs in the first place?

The initiative’s secret weapon is induced pluripotent stem cells, or iPSCs. Similar to most stem cells, they have the ability to transform into anything—a cellular genie, if you will. iPSCs are reborn from regular adult cells, such as skin cells. When transformed into a brain cell, however, they carry the original genes of their donor, meaning that they harbor the original person’s genetic legacy—for example, his or her chance of developing Alzheimer’s in the first place. What if we introduce Alzheimer’s-related genes into these reborn stem cells, and watch how they behave?

By studying these iPSCs, we might be able to follow clues that lead to the genetic causes of Alzheimer’s and other dementias—paving the road for gene therapies to nip them in the bud.

How Going to Mars Could Save Earth

Posted by in categories: 3D printing, nuclear energy, space travel

Article I just wrote about how going to Mars is actually good for protecting life on Earth, too.


People often lump going to Mars or the Moon into a this/that fight when it comes to bettering the life of the Earth and its inhabitants. But, it’s not that simple.

The technology we master in the pursuit of space colonization (starti n g at the Moon and Mars / space stations) will serve to advance that on Earth. The things we learn will help provide a guide for what to do on this future planet, and not just life beyond it. Sure, in-situ resource utilization/production will generate rocket fuel on extraterrestrial bodies. But, things like the NASA Kilopower nuclear reactor can lay the groundwork for alternative energies deployed on Earth at scale. I imagine thorium reactors will follow suit while we still try to deploy fusion at a consumer scale and not just a research basis.

Electrons Waiting Their Turn: New Model Explains 3D Quantum Material

Posted by in categories: chemistry, quantum physics

Scientists from the Cluster of Excellence ct.qmat – Complexity and Topology in Quantum Matter have developed a new understanding of how electrons behave in strong magnetic fields. Their results explain measurements of electric currents in three-dimensional materials that signal a quantum Hall effect – a phenomenon thus far only associated with two-dimensional metals. This new 3D effect can be the foundation for topological quantum phenomena, which are believed to be particularly robust and therefore promising candidates for extremely powerful quantum technologies. These results have just been published in the scientific journal Nature Communications.

Dr. Tobias Meng and Dr. Johannes Gooth are early career researchers in the Würzburg-Dresdner Cluster of Excellence ct.qmat that researches topological quantum materials since 2019. They could hardly believe the findings of a recent publication in Nature claiming that electrons in the topological metal zirconium pentatelluride (ZrTe5) move only in two-dimensional planes, despite the fact that the material is three-dimensional. Meng and Gooth therefore started their own research and experiments on the material ZrTe5. Meng from the Technische Universität Dresden (TUD) developed the theoretical model, Gooth from the Max Planck Institute for Chemical Physics of Solids designed the experiments. Seven measurements with different techniques always lead to the same conclusion.

Somehow This Robot Sticks to Ceilings

Posted by in category: robotics/AI

It’s either some obscure fluid effect or black magic.


Just when I think I’ve seen every possible iteration of climbing robot, someone comes up with a new way of getting robots to stick to things. The latest technique comes from the Bioinspired Robotics and Design Lab at UCSD, where they’ve managed to get a robot to stick to smooth surfaces using a vibrating motor attached to a flexible disk. How the heck does it work?
