Next generation of watch springs
Next generation of watch springs
What happens when something keeps getting smaller and smaller? This is the type of question Empa researcher Johann Michler and his team are investigating. As a by-product of their research completely novel watch springs could soon be used in Swiss timepieces. Applied research is not always initiated by industry - but oftentimes it yields results that can swiftly be implemented by companies.

AI and NMR spectroscopy determine atoms configuration in record time
AI and NMR spectroscopy determine atoms configuration in record time
EPFL scientists have developed a machine-learning approach that can be combined with experiments to determine, in record time, the location of atoms in powdered solids. Their method can be applied to complex molecules containing thousands of atoms and could be of particular interest to the pharmaceutical industry.

Making the impossible possible
Making the impossible possible
A new material for energy-efficient data storage reaches computer operating temperature Multiferroics are considered miraculous materials for future data storage - as long as their special properties can be preserved at computer operating temperatures. This task has now been accomplished by researchers at the Paul Scherrer Institute PSI, with colleagues from Institut Laue-Langevin ILL in Grenoble.

Small flying robots able to pull objects up to 40 times their weight
Researchers from EPFL and Stanford have developed small drones that can land and then move objects that are 40 times their weight, with the help of powerful winches, gecko adhesives and microspines. A closed door is just one of many obstacles that no longer pose a barrier to the small flying robots developed jointly by Stanford University and Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

A fine-tuned laser welds more effectively
Using laser technology Empa scientists optimized a technique to weld the electronics of implantable pacemakers and defibrillators into a titanium case. The medtech company Medtronic is now using the method worldwide to produce these devices. In Tolochenaz (Canton of Vaud) the US medtech company Medtronic produces one out of five heart pacemakers available on the global market and one out of four defibrillators.

A type of moss could prove to be more medically effective than hemp
A type of moss could prove to be more medically effective than hemp
Media releases, information for representatives of the media Media Relations (E) In collaboration with colleagues from the ETH Zurich, researchers at the University of Bern have for the first time investigated a substance found in liverwort, which resembles THC. The psychoactive substance, which is consumed as a "legal high", also exerts analgesic and anti-inflammatory effects, which might be superior to that of THC.

Anti-aging molecule NAD+ gets a boost from blocking an enzyme
Scientists at EPFL have found a new way to boost the famous anti-aging molecule NAD+ in the kidney and liver by blocking an enzyme that limits its production. Publishing in Nature, the researchers have also developed two enzyme blockers that are shown to protect against kidney and liver disease. Nicotinamide adenine dinucleotide (NAD+) is a major player in nutrition today.

Air Pollution and Noise Increase Risk for Heart Attacks
Air Pollution and Noise Increase Risk for Heart Attacks
Air pollution and transportation noise are both associated with an increased risk of heart attacks. Studies on air pollution, which do not take into account traffic noise, tend to overestimate the long-term effect of air pollution on heart attacks. These are the results of a study conducted by researchers from the University of Basel and the Swiss Tropical and Public Health Institute, published in the European Heart Journal.

Nerve-on-a-chip platform makes neuroprosthetics more effective
Nerve-on-a-chip platform makes neuroprosthetics more effective
EPFL scientists have developed a miniaturized electronic platform for the stimulation and recording of peripheral nerve fibers on a chip. By modulating and rapidly recording nerve activity with a high signal-to-noise ratio, the platform paves the way to using chips to improve neuroprosthetic designs.  Neuroprosthetics - implants containing multi-contact electrodes that can substitute certain nerve functionalities - have the potential to work wonders.

New technique reveals limb control in flies - and maybe robots
New technique reveals limb control in flies - and maybe robots
A new neural recording technique developed by EPFL bioengineers enables for the first time the comprehensive measurement of neural circuits that control limb movement. Tested on the fruit fly, results from the technique may inspire the development of more sophisticated robotic control approaches. One of the major goals of biology, medicine, and robotics is to understand how limbs are controlled by circuits of neurons working together.

Roche’s Alecensa (alectinib) significantly reduced the risk of disease worsening or death as a first-line treatment in Asian patients with ALK-positive advanced or metastatic non-small cell lung cancer
Roche's Alecensa (alectinib) significantly reduced the risk of disease worsening or death as a first-line treatment in Asian patients with ALK-positive advanced or metastatic non-small cell lung cancer Head-to-head phase III study of Alecensa versus crizotinib in Asian patient population showed a reduction in the risk of disease worsening or death by 78% Alecensa lowered the risk of tumour spread or growth in the brain or central nervous system

Facilitating handwashing where water is scarce
Facilitating handwashing where water is scarce
Even though the water we've used for washing our hands is barely contaminated, it usually disappears down the drain, never to be used again. A newly developed system allows handwashing water to be recycled, thus not only saving water, but also helping to prevent infectious diseases in developing countries.

Biodiversity Can Also Destabilize Ecosystems
Biodiversity Can Also Destabilize Ecosystems
According to the prevailing opinion, species-rich ecosystems are more stable against environmental disruptions such as drought, hot spells or pesticides. The situation is not as simple as it seems, however, as ecologists have now discovered. Under certain environmental conditions, increased biodiversity can also lead to an ecosystem becoming more unstable.

What does graphene do in our lungs?
What does graphene do in our lungs?
Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa and the Adolphe Merkle Institute (AMI) in Fribourg have now conducted the first studies on a three-dimensional lung model to examine the behavior of graphene and graphene-like materials once they have been inhaled.

Why the Little Ice Age ended in the middle of the 19th century
Why the Little Ice Age ended in the middle of the 19th century
Analysis of ice cores delivers continuous data for the first time on industrial soot from 1740 to today In the first half of the 19th century, a series of large volcanic eruptions in the tropics led to a temporary global cooling of Earth's climate. It was a natural process that caused Alpine glaciers to grow and subsequently recede again during the final phase of the so-called Little Ice Age.

A Selfish Gene Makes Mice into Migrants
A Selfish Gene Makes Mice into Migrants
House mice carrying a specific selfish supergene move from one population to another much more frequently than their peers. This finding of a study shows for the first time that a gene of this type can influence animal migratory behavior. It could help in dealing with invasive plagues of mice. Usually the cooperation of genes helps an organism to grow and flourish.

Using mobile data to model the drinking habits of Swiss youth
Using mobile data to model the drinking habits of Swiss youth
Researchers have carried out a study using smartphone data from young Swiss people to better understand the circumstances in which they are most likely to drink. A computer model developed from the data can estimate, with over 75% accuracy, whether alcohol was consumed on a given weekend night. Do young people drink more out on the town or at a friend's place?
