Designing and re-purposing cell receptors
Designing and re-purposing cell receptors
EPFL scientists have developed a computational method modeling and designing protein allostery that allows the accurate and rational engineering and even re-purposing of cell receptors. The method can be a significant tool for drug development. Called the "second secret of life", allostery is one of the most fundamental processes of biology and has been a central focus among scientists across the life sciences spectrum, from fundamental biology to drug development.

EPFL’s student solves a 100-year-old physics enigma
An EPFL Bachelor's student has solved a mystery that has puzzled scientists for 100 years. He discovered why gas bubbles in narrow vertical tubes seem to remain stuck instead of rising upwards. According to his research and observations, an ultra-thin film of liquid forms around the bubble, preventing it from rising freely.

Controlling the optical properties of solids with acoustic waves
Controlling the optical properties of solids with acoustic waves
Physicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors. One of the main challenges in materials science research is to achieve high tunability of the optical properties of semiconductors at room temperature.

Engineering solutions for kitchen challenges
Crafty engineering can help solve many problems, including those we face in our own kitchens. At EPFL's Institute of Mechanical Engineering, students from three laboratories tackled some of the most common kitchen challenges as part of the first Kitchen-Inspired Engineering contest. Cooking the perfect poached egg is a lot trickier than it looks.

Eliminating cracks in 3D-printed metal components
Researchers at EPFL have developed a new laser 3D-printing technique to manufacture metal components with unprecedented resistance to high temperature, damage and corrosion. The method has applications in fields ranging from aerospace to power-generating turbines. 3D printing, also known as additive manufacturing, has revolutionized the way components are made, setting new standards in terms of production speed when geometric complexity is high.

When grown right, palm oil can be sustainable
When grown right, palm oil can be sustainable
Turning an abandoned pasture into a palm tree plantation can be carbon neutral, according to a new study by EPFL and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). These findings, based on measurements of 56-year-old palm tree plantations in Colombia, suggest we may be able to find sustainable alternatives to deforestation for the production of palm oil - a practice currently under fire by environmentalists.

Stabilizing a cliff using biomineral binders
Stabilizing a cliff using biomineral binders
EPFL spin-off Medusoil has successfully tested its ground-stabilization process on cliffs subject to surface erosion. The company's biomineral-based solution can be used to stabilize sandy and gravelly subsoils to safeguard surrounding infrastructure. It is a long-lasting and easy-to-use alternative to industrial fluids - the production and use of which can be harmful to the environment.

EPFL creates a solar cooker with solid potential in Switzerland
EPFL creates a solar cooker with solid potential in Switzerland
EPFL scientists have developed a glass-paneled solar cooker that delivers exceptional performance. Their patented design can operate an average of 155 days a year in Switzerland's cloudiest regions and up to 240 days in its sunniest. Solar cookers - or solar-powered ovens - can be used to cook foods at low temperatures (60-120°C) for anywhere from 30 minutes up to four hours.

During epidemics, access to GPS data from smartphones can be crucial
A new EPFL and MIT study into the interplay between mobility and the 2013 and 2014 dengue outbreaks in Singapore has uncovered a legal void around access to mobile phone data - information that can prove vital in preventing the spread of infectious diseases. Researchers from EPFL and MIT have shown that human mobility is a major factor in the spread of vector-borne diseases such as malaria and dengue even over short intra-city distances.

Place of residence and sodas, an explosive cocktail
In a groundbreaking study published today, scientists used precision geospatial analysis techniques to show that obesity and the consumption of sugar-sweetened beverages (SSBs) are more prevalent in some parts of Geneva than others. The study, a collaboration between HUG, EPFL, UNIGE and CHUV, is the first of its kind to establish a link between place of residence, SSB consumption and high body mass index (BMI).

A cheaper way to scale up atomic layer deposition
Chemical engineers at EPFL have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply than current approaches, while preserving quality and efficiency. Atomic layer deposition (ALD) involves stacking layers of atoms on top of each other like pancakes.
