Numbers limit how accurately digital computers model chaos
Numbers limit how accurately digital computers model chaos
Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find UCL and Tufts University scientists. The study, published today in Advanced Theory and Simulations , shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread.

Shows we like our math like we like our art: beautiful
Shows we like our math like we like our art: beautiful
A beautiful landscape painting, a beautiful piano sonata - art and music are almost exclusively described in terms of aesthetics, but what about math? Beyond useful or brilliant, can an abstract idea be considered beautiful? Yes, actually - and not just by mathematicians, reports a new study in Cognition.

Thriving animal collectives like ants should move through their environment like ‘savvy gamblers’
Many animals have to move around in their environment to find resources to live and reproduce. Scientists have studied particular examples of this for many years but there are not many unifying frameworks to understand the general organising principles of animal movement. This is especially true for animal collectives like ant colonies, whose individual routes as they search for food can look rather like a 'random walk'.

Common scents don’t always make the best perfumes, suggests mathematical study
Perfumes that use the most popular scents do not always obtain the highest number of ratings, according to an analysis of online perfume reviews. A study of 10,000 perfumes and their online ratings reveals which odours are likely to bring success, with some surprising combinations providing a boost to ratings.

New technique will help experts make heads or tails of male fertility
A new way of analysing sperm that tracks the movement of the sperm tail could enable substantial improvements to male fertility testing. The technique measures the speed and action of the sperm flagellum, or tail, which provides vital information for understanding whether sperm in an ejaculate have the potential to reach and fertilise the egg.

Researchers crack an enduring physics enigma
Researchers crack an enduring physics enigma
Researchers from EPFL have found the mechanism that lies behind a mysterious physics phenomenon in fluid mechanics: the fact that turbulence in fluids spontaneously self-organizes into parallel patterns of oblique turbulent bands - an example of order emerging spontaneously from chaos. In so doing, they solved a problem that had stumped generations of physicists.

From "counting words" to the Digital Humanities
Nowadays, Digital Humanities is a booming subject, but it has a long history. "Quantitative Literary Studies" at the University of Stuttgart investigates how computational methods have been used for the analysis and interpretation of language and literature since the early 19th century. The German Research Foundation (DFG) has now approved the continuation of the project.

Challenges claim that 2-million-year-old fossil is human ancestor
Statistical analysis of fossil data shows that it is unlikely that Australopithecus sediba , a nearly two-million-year-old, apelike fossil from South Africa, is the direct ancestor of Homo , the genus to which modern-day humans belong. The research by paleontologists from the University of Chicago , published this week in Science Advances , concludes by suggesting that Australopithecus afarensis , of the famous "Lucy" skeleton, is still the most likely ancestor to the genus Homo .

Opportunistic cancer cells ’slip through the gaps’ to spread through blood vessels
Cancer cells may rely on opportunism, as well as chemical signalling, to spread through the body, according to new findings by mathematicians at the University of Birmingham. Cancer spreads by sending cells out from the primary tumour to travel through the vascular or lymphatic system to colonise other organs in a process called metastasis.

Bristol mathematician cracks Diophantine puzzle
A mathematician from the University of Bristol has found a solution to part of a 64-year old mathematical problem - expressing the number 33 as the sum of three cubes. Since the 1950s, mathematicians have wondered if all whole numbers could be expressed as the sum of three cubes; whether the equation k = x³+ y³+ z³ always has a solution.

One term - three different interpretations
One term - three different interpretations
As different as the term "dynamic" is used and understood in science, so diverse are the research areas of the University of Münster, in which dynamic even plays a central role in the title. Prof. Christopher Deninger and Prof. Mario Ohlberger from the Cluster of Excellence "Mathematics Münster", the lawyer Prof. Nils Jansen from the Cluster of Excellence "Religion and Politics" and the biochemist Prof. Lydia Sorokin from Cells-in-Motion Cluster of Excellence explain what they understand by the term in their research.

Swimming microbes steer themselves into mathematical order
For News Media FOR IMMEDIATE RELEASE × A sheet of tiny swimming organisms that "push" themselves through fluid with, say, flagella, create forces in the liquid that bend the sheet in asymmetric, shrinking folds. Image courtesy of Saverio Spagnolie Freeing thousands of microorganisms to swim in random directions in an infinite pool of liquid may not sound like a recipe for order, but eventually the swarm will go with its own flow.
