**1**-**17**of**17**. A key role for quantum entanglement

A method known as quantum key distribution has long held the promise of communication security not possible in conventional cryptography. For the first time, an international team of scientists, including researchers from EPFL, has demonstrated experimentally an approach to quantum key distribution based on high-quality quantum entanglement - offering much broader security guarantees than previous schemes.

Secure cryptography with real-world devices is now a realistic possibility

New research published in Nature explains how an international team of researchers have, for the first time, experimentally implemented a type of quantum cryptography considered to be the 'ultimate', 'bug-proof' means of communication.

Discovered a mathematical principle that explains how cells connect with each other to form tissues and organs

An international team of scientists has discovered a new mathematical principle that explains how cells connect with each other to form tissues, an important step forward in understanding how organs are formed during embryonic development and the pathologies associated with this process. The finding is led by the Institute for Integrative Systems Biology (I2SysBio), a joint center of the Spanish Research Council (CSIC) and the University of Valencia (UV), and the Institute of Biomedicine of Seville (IBiS), the Virgen del Rocío University Hospital, and the University of Seville.

Knots in the resonator: elegant math in humble physics

At the heart of every resonator - be it a cello, a gravitational wave detector, or the antenna in your cell phone - there is a beautiful bit of mathematics that has been heretofore unacknowledged. Yale physicists Jack Harris and Nicholas Read know this because they started finding knots in their data.

As they search for beauty

At its heart, is mathematics an aesthetic discipline? Or what does it mean if someone finds a proof -beautiful- And what does mathematical beauty say about physical connections? To this day, mathematics includes beautiful facts that are also familiar to us in everyday life. The golden ratio, for example, has been revered since antiquity as representing the most aesthetically pleasing proportions.

AI reveals unsuspected math underlying search for exoplanets

Artist's concept of a sun-like star (left) and a rocky planet about 60% larger than Earth in orbit in the star's habitable zone. Gravitational microlensing has the ability to detect such planetary systems and determine the masses and orbital distances, even though the planet itself is too dim to be seen.

How cells correct errors under time pressure

How does a cell balance risk and speed when dividing? scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently. Cells go through a life cycle that includes growing to the right size, being equipped to perform its functions, and finally dividing into two new cells.

Algorithm predicts which students will drop out of Math courses

In the subjects of science and technology, engineering and mathematics - known collectively as STEM subjects - up to 40 percent of students drop out of their studies in the entry phase. A research team from the University of Tübingen's Methods Center at the Faculty of Economics and Social Sciences has now developed a statistical method that can be used to predict on average eight weeks in advance whether students will terminate their studies.

Enhancer-promoter interactions - distance matters

When and where a gene is transcribed in a living organism often depends on its physical interactions with distal genomic regulatory regions called enhancers. Researchers in the group of Luca Giorgetti have thrown light on how such interactions control transcription thanks to a novel ingenious experimental approach combined with mathematical modelling.

Build neurons with mathematics

Researchers from EPFL have found a way to use only mathematics to automatically draw neurons in 3D, meaning we are getting closer to being able to build digital twins of brains. Santiago Ramón y Cajal, a Spanish physician from the turn of the 19 th century, is considered by most to be the father of modern neuroscience.

Mathematics helps AI in biomedicine

"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.

Computer model shows the best ways to slow the spread of COVID-19

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.

A mathematical model may help explain how blood circulates in the brain

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.
