It’s the spin that makes the difference
Biomolecules such as amino acids and sugars occur in two mirror-image forms - in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.

A sustainable fuel and chemical from the robotic lab
Artificial intelligence and automated laboratory infrastructure are massively accelerating the development of new chemical catalysts. With these tools, researchers at ETH Zurich are developing catalysts for efficiently and cost-effectively synthesising the energy source methanol from CO2. Catalysts are chemistry's hard-working little helpers.

GPT-3 transforms chemical research
Scientists at EPFL demonstrate how GPT-3 can transform chemical analysis, making it faster and more user-friendly. Artificial intelligence is growing into a pivotal tool in chemical research, offering novel methods to tackle complex challenges that traditional approaches struggle with. One subtype of artificial intelligence that has seen increasing use in chemistry is machine learning, which uses algorithms and statistical models to make decisions based on data and perform tasks that it has not been explicitly programmed for.

How to make bright quantum dots even brighter
Researchers at Empa and ETH have developed methods for making perovskite quantum dots faster and more efficient emitters, thereby significantly improving their brightness. This is relevant for applications in displays as well as in quantum technologies. Quantum dots are a kind of artificial atom: just a few nanometres in size and made of semiconductor materials, they can emit light of a specific colour or even single photons, which is important for quantum technologies.

’Mini-placentas’ shed light on early events that are key for a successful pregnancy
The placenta provides oxygen and nutrients to a growing baby, but its early interactions with a mother's uterus remain an enigma.

New agent blocks stress response
If the body's natural stress response gets knocked off balance, it can result in physical and mental health disorders. Researchers at ETH Zurich have developed an agent capable of selectively inhibiting this response. Stress isn't merely an oppressive feeling we experience when we're overwhelmed; it's the body's natural reaction to acute or persistent strain.

Capturing greenhouse gases with the help of light
Researchers at ETH Zurich are developing a new method to remove CO2 from the atmosphere. It involves molecules that become acidic when exposed to light. Their new process requires much less energy than conventional technologies. If we want to slow down global warming, we need to drastically reduce greenhouse gas emissions.
