A game changer for building robust distributed systems
A game changer for building robust distributed systems
Researchers have developed a new distributed algorithm that, for the first time, solves one of the key performance and reliability problems affecting most of the currently-deployed consensus protocols. Consensus is one of the fundamental problems in distributed systems. It allows a group of machines to maintain multiple copies of data and update them consistently, even when a fraction of the machines might fail.

Rapid early detection of drug resistance in cancer patients
Rapid early detection of drug resistance in cancer patients
Parithera, an EPFL spin-off, has developed a system that lets doctors detect drug resistance in cancer patients early on, saving precious time and preventing the unnecessary use of treatments with onerous side effects. Drug resistance is a major problem in the treatment of cancer. Some cancer cells demonstrate resistance right at the start of a new therapy, while others develop it over the course of several months or years.

Ultrathin films achieve record hydrogen separation
Ultrathin films achieve record hydrogen separation
Scientists at EPFL have synthesized the first ever metal-organic frameworks membrane with thickness of just one unit cell. The ultrathin film yields record-high separation performance of hydrogen-nitrogen. Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores. These pores give MOFs record-breaking internal surface areas, which make them extremely versatile for a number of applications: separating petrochemicals and gases , mimicking DNA , producing hydrogen , and removing heavy metals , fluoride anions , and even gold from water are just a few examples.

2050: 10 billion people need to be fed
When it comes to feeding a growing population at a time of conflict and climate change, Mother Earth has a lot on her plate. To build a sustainable future we'll need to return to a farm-to-table model, and that's opening up vast and exciting avenues of research for scientists in an array of fields. In this special report , we explore some of the developments taking place in research labs and out on the farm.

A deep look into the progression of Parkinson's Disease
A deep look into the progression of Parkinson's Disease
Scientists at EPFL use cutting-edge imaging techniques to shed light on the progression of Parkinson's disease by studying how the main culprit, the protein alpha-synuclein, disrupts cellular metabolism. Parkinson's disease is a complex neurodegenerative disorder that leads to the deterioration of specific types of neurons in the brain, resulting in a number of motor and non-motor symptoms.
