"Data is the new oil", it has often been said. Indeed, in the digital age data is the fuel that runs the engines of digital media, advanced informatics (AI, machine learning etc.) and, not least, scientific research. Nevertheless, when facing certain highly complex issues, data-driven approaches may not always be the most effective solutions.

Researchers simulate the transmission of variants and effects of health measures By Researchers at the University of Waterloo created the first computational model that simulates many variables affecting the transmission of COVID-19 to slow the spread of variants. The model takes raw data already in use to forecast case numbers and hospitalizations, and then adds other factors, such as vaccination rates, the use of masks and lockdowns, and the number of breakthrough infections.

Research carried out by the Universidad Carlos III de Madrid (UC3M) may help us better understand oscillations in blood flow that occur in the cerebrovascular network, thanks to a theoretical model that allows the flow and accumulation of fluid (in this case, blood) to be taken into account. Flow networks are made up of a set of connections that carry fluid.

A multidisciplinary team at the University of Geneva has succeeded in explaining the complex distribution of scales in the ocellated lizard by means of a simple equation. The shape-shifting clouds of starling birds, the organization of neural networks or the structure of an anthill: nature is full of complex systems whose behaviors can be modeled using mathematical tools.

Returning to in-person experiences in February: for more information. The computational models will help medical practitioners better understand the physiology of the kidneys during pregnancy Researchers are using computer simulations to better understand the impacts pregnancy can have on kidneys. The new research will help medical practitioners better understand the physiology of the kidneys during pregnancy and develop appropriate patient care and treatments to improve health outcomes.

Sydney researcher Professor Geordie Williamson is working with colleagues at Oxford using DeepMind's artificial intelligence to develop fundamentally new techniques in mathematics. For the first time, computer scientists and mathematicians have used artificial intelligence to help prove or suggest new mathematical theorems in the complex fields of knot theory and representation theory.

For the first time, mathematicians have partnered with artificial intelligence to suggest and prove new mathematical theorems. The work was done in a collaboration between the University of Oxford, the University of Sydney in Australia and DeepMind, Google's artificial intelligence sister company. While computers have long been used to generate data for mathematicians, the task of identifying interesting patterns has relied mainly on the intuition of the mathematicians themselves.

Light is used for various purposes in nowadays applications. For example, data can be transmitted with light and nanoscopic structures can be created by light. To enable such applications, light must be structured. To do this, its properties - intensity (brightness), phase (position in oscillation-cycle) and polarization (direction of the oscillation) - are "tailored".

A team from the University of Geneva has implemented a new way to secure data transfers based on the physical principle of relativity. The volume of data transferred is constantly increasing, but the absolute security of these exchanges cannot be guaranteed, as shown by cases of hacking frequently reported in the news.

An international collaboration with EPFL has developed a method to improve the performance of COVID-19 contact-tracing apps by taking into account a user's recent contacts, risk levels and shared information about tests and symptoms. Contact-tracing apps like SwissCovid have enormous potential to mitigate the spread of the COVID-19 pandemic.

Three-dimensional (3D) configurations of atoms dictate all materials properties. Quantitative predictions of accurate equilibrium structures, 3D coordinates of all atoms, from a chemical graph, a representation of the structural formula, is a challenging and computationally expensive task which is at the beginning of practically every computational chemistry workflow.

An international research team of cryptographers completed a detailed security analysis of the popular Telegram messaging platform identifying several weaknesses in its protocol that demonstrate the product falls short of some essential data security guarantees. Working with only open-source code and without "attacking" any of Telegram's running systems, a small team of international researchers completed a detailed analysis of the company's encryption services.

The term Bose-Einstein condensate describes a state of matter in which atoms or elementary particles combine into a single quantum mechanical object during extreme cooling. Science does not yet fully understand exactly how these macroscopic states - beyond the confines of traditional physics - develop from a thermal atomic cloud in just a few milliseconds and when statistical equilibrium is reached, according to Georg Wolschin.

Researchers from the Universidad Carlos III de Madrid (UC3M) have created a mathematical model and simulated numerically the progression of age-related macular degeneration, one of the main causes of blindness. This model can be used to better understand how this disease appears and assess the most effective treatments.

Engineers at EPFL and École Polytechnique in France analyzed the friction between pages in a book and the mechanical force needed to bend them. Drawing on their experiments, they developed a new theoretical model for predicting the elasto-frictional behavior of stacked layers. It all started with a shaky washing machine.

Study on use of tablets in mathematics Low-achieving pupils benefit more in mathematics lessons from learning materials on tablet PCs than high-achieving children. They are obviously helped by individualized learning paths, immediate feedback and the hands-on processing of interactive content. This conclusion was reached in a study conducted by the Technical University of Munich (TUM) with sixth-grade students.

Mathematicians find core mechanism to calculate tipping points Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers at the Technical University of Munich (TUM) have discovered a universal mathematical structure at these so-called tipping points.

The use of credit cards and other cashless or digital payment methods has become the norm for consumers all over the globe, and the strong surge of online buying during the pandemic has further boosted this decade-long trend. However, behind the convenience of 'click and pay' there are also risks, such as fraud and related losses, which are mostly borne by the card companies.

Mechanical engineers and mathematicians at EPFL have joined forces to gain a better understanding of the geometry and mechanics of two filaments in contact - as in the cases of knots and woven fabrics. Pedro Reis, head of EPFL's Flexible Structures Laboratory, and John Maddocks, head of EPFL's Laboratory for Computation and Visualization in Mathematics and Mechanics, have something in common: a fascination with ropes and knots.
