From heroin addiction to alcohol-related problems
From heroin addiction to alcohol-related problems
Around 3,000 heroin addicts currently receive opioids such as methadone, buprenorphine or morphine as part of their treatment in the Canton of Zurich.

Cells adapt ultra-rapidly to zero gravity
Cells adapt ultra-rapidly to zero gravity
Mammalian cells are optimally adapted to gravity. But what happens in the microgravity environment of space if the earth‘s pull disappears' Previously, many experiments exhibited cell changes – after hours or even days in zero gravity. Astronauts, however, returned to Earth without any severe health problems after long missions in space, which begs the question as to how capable cells are of adapting to changes in gravity.

Using magnetic gates to track slalom skiers' performance
Using magnetic gates to track slalom skiers' performance
EPFL researchers can now measure a slalom skier's exact time at each gate all the way down the slope. Their system also calculates the skiers' speed and trajectory more accurately than GPS. Whether they're racing the slalom or giant slalom, skiers all face the same imperative: to round the gates as fast as possible.

Rare proteins collapse earlier
Rare proteins collapse earlier
Some organisms are able to survive in hot springs, while others can only live at mild temperatures because their proteins aren't able to withstand such extreme heat. ETH researchers investigated these differences and showed that often only a few key proteins determine the life and heat-induced death of a cell.

New computer model shows how proteins are controlled
New computer model shows how proteins are controlled "at a distance"
EPFL scientists have created a new computer model that can help better design of allosteric drugs, which control proteins ‘at a distance'. Enzymes are large proteins that are involved in virtually every biological process, facilitating a multitude of biochemical reactions in our cells. Because of this, one of the biggest efforts in drug design today aims to control enzymes without interfering with their so-called active sites - the part of the enzyme where the biochemical reaction takes place.

Prospect for more effective treatment of nerve pain
Prospect for more effective treatment of nerve pain
The sharp pain shoots to the face or teeth and seriously torments patients. Known as trigeminal neuralgia, it is one of the worst chronic nerve pains. The bouts are triggered by touch, such as shaving, putting on make-up, showering, talking and tooth brushing, or even a gust of wind. The cause is usually an irritation of the trigeminal nerve, the cranial nerve responsible for the sensory innervation of the facial area, parts of the scalp, and the oral cavity.

Less snow and a shorter ski season in the Alps
Less snow and a shorter ski season in the Alps
After long-awaited snowfall in January, parts of the Alps are now covered with fresh powder and happy skiers. But the Swiss side of the iconic mountain range had the driest December since record-keeping began over 150 years ago, and 2016 was the third year in a row with scarce snow over the Christmas period.

Laissez-faire is not good enough for reforestation
Laissez-faire is not good enough for reforestation
If degraded and logged areas of tropical forests are left to nature, the populations of certain endangered tree species are not able to recover. This applies in particular to trees with large fruit where the seeds are distributed by birds, as ETH scientists have shown in a rainforest in India. In order to restore tropical rainforests, it is not enough to simply set up protected areas and leave them to their own devices.

Frequency combs: on-chip integration on track
Frequency combs: on-chip integration on track
EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits. A compact, precision tool for counting and tracking laser frequencies may improve atomic clocks and optical data transmission devices.

Measuring entropy
Measuring entropy
A scanning-tunneling microscope (STM), used to study changes in the shape of a single molecule at the atomic scale, impacts the ability of that molecule to make these changes - the entropy of the molecule is changed and, in turn, can be measured.

Success by deception
Success by deception
Theoretical physicists from ETH Zurich deliberately misled intelligent machines, and thus refined the process of machine learning. They created a new method that allows computers to categorise data - even when humans have no idea what this categorisation might look like. When computers independently identify bodies of water and their outlines in satellite images, or beat the world's best professional players at the board game Go, then adaptive algorithms are working in the background.

Tapping into underground urban heat islands
Cities are heat islands - not only above ground but below ground too, and therein lies the enormous potential to better harness this energy through geothermal heat exchangers.

Explosion in species diversity due to hybridization
No less than 500 new species of cichlids, brightly coloured perch-like fish, evolved in Lake Victoria (East Africa) over the past 15,000 years - a record in the animal and plant world.

Taming complexity
Taming complexity
Quantum systems consisting of many particles are a major challenge for physicists, since their behaviour can be determined only with immense computational power. ETH physicists have now discovered an elegant way to simplify the problem. Classical physics offers a relatively easy approach to describing how objects move in our everyday world.

Measuring time without a clock
EPFL scientists have been able to measure the ultrashort time delay in electron photoemission without using a clock. The discovery has important implications for fundamental research and cutting-edge technology.

Genetic defects in tooth enamel conducive to development of caries
Why do some people develop caries even though they always brush their teeth carefully while others are less stringent regarding dental hygiene yet do not have any holes' Ultimately, both have bacteria on the surface of their teeth which can attack the enamel. Enamel forms via the mineralization of specific enamel proteins.

New study into leukemia offers clearer understanding of its biology
New study into leukemia offers clearer understanding of its biology
EPFL scientists have made an extensive study in the cause of leukemia that could greatly improve the way we treat the disease. Leukemia affects 350,000 people worldwide. It is a cancer of the white blood cells, which are the cells of the immune system and are produced by stem cells in the bone marrow. There are two types of chronic and two types of acute leukemia.
