**1**-**20**of**28**. A new method for boosting the learning of mathematics

UNIGE researchers oversaw a new system of maths learning whose purpose is to promote the use of arithmetic formulas at an early age. After a year, they observed a leap in students' performance. How can mathematics learning in primary school be facilitated? A recent study conducted by the University of Geneva (UNIGE), Switzerland, had shown that our everyday knowledge strongly influences our ability to solve problems, sometimes leading us into making errors.

How stable are ancient structures?

From mobile phone photo to static calculations Cracks in the ankles of Michelangelo's David statue, damaged columns in the cistern of the Hagia Tekla Basilica: Are these ancient structures in danger of collapsing? Researchers at Technical University of Munich (TUM) have developed a new process that makes it possible to assess the mechanical condition of structures based on photographs.

Plundervolt exposes vulnerability in security technology of Intel processors

Computer scientists from imec-DistriNet (KU Leuven), the University of Birmingham, and TU Graz have shown that the possibility to adjust the operating voltage of Intel processors makes them vulnerable to attack. Modern processors are being pushed to perform faster than ever before, and with this come increases in heat and power consumption.

Mathematicians’ Work Helps Change How People Vote

Wes Pegden's expert testimony has changed the future of how states draw electoral districts As U.S. courts debate gerrymandering - the process of carving up electoral districts to disproportionately benefit one political party - Wes Pegden's work is helping to shape redistricting maps more fairly.

Could mathematics help to better treat cancer?

Using the information theory, researchers at UNIGE aim to better understand the cancerous development of cells through a mathematical approach and propose innovative therapeutic strategies. The development and survival of living beings are linked to the ability of their cells to perceive and respond correctly to their environment.

With Giotto, artificial intelligence gets a third dimension

The Giotto project, launched by EPFL startup Learn to Forecast, intends to revolutionize the way we use artificial intelligence. Drawing on the science of shapes, Giotto pushes AI forward by making it more reliable and intuitive in areas such as materials science, neuroscience and biology. Giotto is open-source and available free of charge on GitHub, and it's already being used by some EPFL scientists.

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.

Jeanne Calment was indeed the oldest human being

By combining epidemiology, mathematical modelling and historical investigation, researchers in Geneva, Switzerland and France confirm Jeanne Calment's exceptional longevity, invalidating the conspiracy theories surrounding her. Jeanne Calment, who passed away in 1997 at 122 years and 165 days, still is today the human being who had the longest life.

UQ data scientist cracks near century old crypto-code

One of the most challenging unsolved cryptograms of the Irish Republican Army - created in the 1920s - has been decoded for the first time by a University of Queensland data scientist. The solution to the cipher has evaded cryptologists for years, but through perseverance and skill Dr Richard Bean managed to develop a program to crack the code.

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'.

Expert mathematicians stumped by simple subtractions

UNIGE researchers have shown that our general knowledge about the world interferes with our ability to solve basic mathematical problems, even among experts in the field. Mathematical thought is seen as the pinnacle of abstract thinking.

Simulating quantum systems with neural networks

A new computational method, based on neural networks, can simulate open quantum systems with unprecedented versatility. The method was independently developed by physicists at EPFL, France, the UK, and the US, and is published in Physical Review Letters. Even on the scale of everyday life, nature is governed by the laws of quantum physics.

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 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.

Support for Conservative Party rises with UK house prices

Support for Conservative Party rises with UK house prices, new research reveals The big increase in housing wealth inequality in the UK over the period from 1995 to 2007 increased homeowners' probability of supporting the Conservative party. However, it did not make homeowners more averse to the state's ownership of public services.

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.
