How Can the Enantiomers of a Chiral Molecule be Separated More Effectively?
See details
(Germany: Latest Thinking, 2017), 20 mins
Chiral molecules are molecules that behave as image and mirror image to each other; these are also called enantiomers. There is a demand in pure enantiomers, which can be created for the use of a variety of industries, such as drugs for the pharmaceutical industry or herbicides for agrochemistry. ANDREAS SEIDEL-MO...

How Can the Statistical Properties of a Turbulent Flow Be Calculated?
See details
(Germany: Latest Thinking, 2017), 12 mins
For more than one hundred years, scientists are working to uncover how turbulent flows occur. This would enable them among others to predict how pollutants spread in water or how pollen travel in air. As EBERHARD BODENSCHATZ explains in this video, new insides are offered by an approach based on Lagrangian Particl...

How Can the Statistical Properties of Cosmic Structures Be Calculated with Simple Physical Laws?
See details
(Latest Thinking, 2017), 12 mins
So far, the understanding we have of cosmic structures comes from numerical simulations. As MATTHIAS BARTELMANN explains in this video, his research group has developed a different method to calculate the statistical properties of cosmic structures in order to better understand why they evolve in the way they do....

How Can We Experimentally Determine Why Hydrogen Atoms Are Absorbed on Metal Surfaces?
See details
(Germany: Latest Thinking, 2017), 12 mins
Although very light weight, hydrogen atoms have a high probability to be absorbed by a metal surface upon collision. In this video, OLIVER BÜNERMANN explains collision experiments carried out to determine why this is the case. During the experiment, they shot a hydrogen atom beam at a gold surface and at an insul...

How Can We Find the Cause of the Accelerated Expansion of the Universe?
See details
(Latest Thinking, 2017), 11 mins
Galaxies keep drifting apart from one another. This is because the universe is expanding in an accelerated way. It is mostly composed of matter and thus the acceleration should slow down because matter carries gravity and gravity is a force which pulls, but does not push, if one neglects the cosmological constant....

How Can We Historically Describe the Evolution of Knowledge and How Can We Account for It?
See details
(Latest Thinking, 2017), 11 mins
The history of science traditionally focuses on specific time periods or on scientists that made important discoveries. The research presented in this video by JÜRGEN RENN broadens the perspective and looks at the history of knowledge more generally. With the goal to investigate how knowledge evolves historically...

How Can We Predict What Happens at an Event Horizon?
See details
(Latest Thinking, 2017), 9 mins
Every galaxy seems to have a supermassive black hole in its center. A black hole is defined as such because nothing can escape from a certain point inside, not even light. There is, however, a last stable orbit which is called the event horizon outside of which gas can still radiate away. This event horizon might...

How Can We Prevent Network Security Problems in Smartphone Apps?
See details
(Latest Thinking, 2017), 9 mins
Many android apps that try to use SSL to secure network communication fail in doing so and are insecure. By detecting such security flaws and interviewing the developers, the study presented in this video shows the necessity of rethinking how developers interact with security code. As shown, developers are not, as...

How Can We Use Machine Learning in the Search for Exoplanets?
See details
(Germany: Latest Thinking, 2018), 14 mins
Exoplanets are planets beyond our own solar system. Since they do not emit much light and moreover are very close to their parent stars, they are difficult to detect directly. When searching for exoplanets, astronomers use telescopes to monitor the brightness of the parent star under investigation: Changes in brig...

How Could the Modern Human Succeed over Other Hominids?
See details
(Latest Thinking, 2017), 11 mins
Modern humans colonized the whole planet and replaced all other hominids, such as Neanderthals. This evolvement raises interesting evolutionary questions concerning both species. The paleoanthropological research presented in this video looks at a moment in time when both co-existed. In order to find out about the...
