The riddle of the icy droplets

In order to understand atmospheric processes, it is necessary to discover how ice nuclei form within clouds. This is the task of the INUIT research group, to which Johannes Gutenberg University Mainz (JGU) is contributing. A team in the laboratory of the Institute of Atmospheric Physics is working with small drops, a wind tunnel like no other in the world, and a special cold chamber that will help find answers to these fundamental questions.

Tracking the climate by airplane

Professor Peter Hoor and his Airborne Measurements and Transport Processes work group at the Institute of Atmospheric Physics at Johannes Gutenberg University Mainz (JGU) are studying the processes that occur in the tropopause. The events that take place in this boundary layer between the stratosphere and the troposphere are still puzzling scientists but have significant effects on the climate of our planet.

Not everything in the universe is symmetrical

Research into fundamental symmetries and a unique nationwide cooperation between Johannes Gutenberg University Mainz (JGU) and the Helmholtz Association have brought Professor Dmitry Budker to Mainz. He will be heading up the Matter Antimatter Symmetry section at the JGU-based Helmholtz Institute Mainz, which collaborates with the GSI Helmholtz Center for Heavy Ion Research in Darmstadt.

What holds matter together?

Subatomic particles, muons, quarks, gluons, and their cousins: Physicists working with the MAMI electron accelerator at Johannes Gutenberg University Mainz (JGU) are also playing an important role in the BESIII Experiment in Beijing in China. They are on the trail of the basic building blocks of matter and are thus hoping to pave the way for a New Physics.

Research at the interface of disciplines

Thirty years ago the first Professor of Computer Science was appointed at Johannes Gutenberg University Mainz (JGU). A lot has since changed in this relatively recent field. This special anniversary is a good reason to take a quick look back, despite the fact that the professors at the Institute of Computer Science prefer to talk about their current work and projects. After all, the present and future are far more interesting to them than a brief history of their discipline.

Hunting neutrinos in the Antarctic

Over the past three years, the IceCube neutrino observatory at the South Pole has managed to detect extreme high energy neutrinos originating from the depths of the universe. Even experts doubted for a long time whether the idea would work, but reports of success came in 2013. Professor Lutz Köpke of the Institute of Physics at Mainz University and his work group are involved in the international research project.

Cattle, milk, and Europeans

With their article on "The milk Revolution," Professor Joachim Burger and his work group at the Institute of Anthropology at Johannes Gutenberg University Mainz (JGU) managed to catapult themselves into the media headlines. But milk in fact only represents an incidental aspect of their research. Their real concern is the history of the settlement of Europe.

A journey through 470 million years of plant history

There is hardly any other place at Johannes Gutenberg University Mainz (JGU) that is as inviting to relax or take a stroll as the Botanic Garden. However, it is much more than simply a recreational facility. The garden is a place of research and teaching while it also provides a storehouse of rare plants, which is the largest of all the collections present on campus.

History in skulls

Over the past three years, PD Dr. Holger Herlyn of the Institute of Anthropology at Johannes Gutenberg University Mainz (JGU) has assembled a modern teaching collection of replica skulls that document the development of human beings and their relationship to other primates. The exhibits in the collection's display cabinets are ready to be investigated by the probing hands of the students.

The climate remains a mystery

In his book Geschichte des Klimas (A history of the climate), one of the leading paleoclimate researcher takes us on a journey through the geological eras. Professor Dr. Frank Sirocko of the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU) provides insight into the past while also venturing to forecast the future.

The collection is growing and growing

The herbarium at Johannes Gutenberg University Mainz (JGU) is hardly known – although it includes a number of rare plants and fungi, some of which are still awaiting proper classification. In addition to the extensive array of fungi and plants native to the Rhineland-Palatinate region and gathered from the Mainz Sand Dunes nature reserve, there are also exotic specimens from Costa Rica and Rwanda. Dr. Gudrun Kadereit shows what the herbarium has in store.

Hunting down clouds in a spy jet

Two of the most important factors influencing climate events are still a mystery: The clouds and the aerosols in the Earth's upper atmosphere. Professor Dr. Stephan Borrmann is tracking them both down. A new, large-scale project is ready to start in the skies above India. The European Union is providing EUR 2.75 million in financial support.

Mollusks chronicle the climate

Mammoths and mussels, dragonflies and corals: the Paleontology Collection at the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU) is incredibly diverse. What's missing is a proper curator. Because the million or so specimens in the collection are too much for anyone to manage on a part-time basis.

When ants stir up a rebellion

It has long been known that certain ants keep other ants as slaves. However, Professor Dr. Susanne Foitzik of the Institute of Zoology at Johannes Gutenberg University Mainz (JGU) has discovered that these slaves have what it takes to rebel. And she can explain how this ability has developed during the course of evolution.

Finnish trees tell the story of 2,000 years of climate history

Over the past 2,000 years, the climate in northern Europe has cooled more than previously assumed. This is the conclusion drawn by an international group of researchers following the examination of the growth rings of fossilized pines from Finnish Lapland. Scientists from Johannes Gutenberg University Mainz (JGU) also took part in this major project, most notably the climate geographer Professor Dr. Jan Esper.

Renewable resources

The magic word that promises to facilitate energy transition is "renewable resources". They seem like the perfect solution: environmentally neutral, versatile, and constantly replenishing themselves. But are they really a panacea? Dr. Ralf Omlor, custodian of the Botanic Garden at Johannes Gutenberg University Mainz (JGU), is using the occasion of the "Renewable Resources – Plants, Products, Perspectives" Week to put his case that we need to take a more critical approach to this complex aspect.

Immortal minerals

The Mineralogical Collection of the Institute of Geosciences is housed in a simple room with 60s charm. Here, rubies, emeralds, gold, and much more sparkle in plain glass cabinets. Professor Dr. Wolfgang Hofmeister guards these treasures and is responsible for adding new items – sometimes even vaporizing a diamond in the service of science.

A molecule folds itself into a solar sail

Professor Dr. Harald Paulsen and his team are researching the characteristics of the light-harvesting protein LHCII. The protein and its unusual self-organization skills have fascinated biologists for twenty years. It plays an important role in photosynthesis and may one day majorly increase the efficiency of solar cells.

Higgs boson electrifies Mainz physicists

Matthias Neubert and his team are elated since scientists at Geneva's CERN research center found the first indications of the existence of the Higgs boson. This is the last building block missing from the standard model of physics. The head of the Theoretical Elementary Particle Physics unit at Johannes Gutenberg University Mainz (JGU) now expects his area of research to take off.
