We humans benefit from the oceans' tremendous capacity to absorb greenhouse gases. Due to the low temperature of the water, the Arctic Ocean absorbs an especially large amount of CO2 in relation to its size. Due in part to climate change, this effect will be less pronounced in the future. A new study released by Universität Hamburg's Cluster of Excellence CLICCS shows how much CO2 is released into the atmosphere in the Arctic Ocean by the erosion of coastal permafrost.

A team of scientists headed by Professor Ingo Krossing from the Department of Inorganic Chemistry at the University of Freiburg has succeeded in significantly increasing classic reagents' potential for oxidation. A team of scientists headed by Professor Ingo Krossing , Professor of Molecular and Coordination Chemistry at the University of Freiburg's Institute of Inorganic and Analytical Chemistry, has succeeded in significantly increasing the potential for oxidation of  and  positive ions.

Aerobic methane-oxidizing bacteria are also permanently active in oxygen-free water Methane-oxidizing bacteria could play a greater role than previously thought in preventing the release of climate-damaging methane from lakes, researchers from Bremen report. They also show who is behind the process and how it works.

Further action needed according to a University of Bonn study on child and adolescent nutrition A high-sugar diet is seen as a risk factor for obesity and chronic illness. University of Bonn researchers have analyzed data on sugar intake among children and adolescents in a long-term study, finding that intake has been declining steadily since 2010-but is still above the level recommended by the World Health Organization (WHO).

Nanotubes can serve as biosensors. They change their fluorescence when they bind to certain molecules. Until now, it was unclear why. Researchers have gained new insights into the cause of the fluorescence. Researchers from Bochum and Texas have discovered why carbon nanotubes fluoresce when they bind to certain molecules.

Heidelberg researchers successfully develop a new generation of biocompatible materials for additive manufacturing Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as "biofactories" for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments.

A new combination of single infrared light measurement and machine learning can be used to detect metabolic disorders and high blood pressure Some common diseases could be easier and quicker to diagnose in future. A team from the Max Planck Institute of Quantum Optics, the Ludwig Maximilian University of Munich and the Helmholtz Zentrum München has demonstrated in a representative study that infrared light measurements of blood plasma when combined with machine learning can be used to detect various metabolic disorders such as type-2 diabetes and high blood pressure.

Memory loss, confusion, speech problems - Alzheimer's disease is the most common cause of dementia, affecting about 35 million people worldwide, and the number is growing. The protein amyloid beta, which occurs naturally in the brain, plays a central role in the disease: It accumulates in patients in insoluble clumps that form plaques between neurons in the brain, damaging them.

Prerequisite for protective effects of fasting is an increase in the concentration of the endogenous substance spermidine in the organism / international study involving the team of Stephan Sigrist from Freie Universität According to the results of an international study involving the Freie Universität Berlin, fasting can prolong life and increase the health span.

As summer temperatures rise, the health risks caused by heat increase. This particularly affects urban areas and cities such as Heidelberg with a high building density and limited green spaces. The heat island effect, which describes the higher temperatures in inner-city areas compared to the surrounding area, leads to an increase in heat-related illnesses, especially among vulnerable population groups such as the elderly, children and people with pre-existing conditions.

The protective effects of fasting depend on an increase in the concentration of spermidine, according to an international study involving a team led by Professor Stephan Sigrist from Freie Universität Berlin According to the findings of an international study, fasting can extend people's lifespan and increase overall health.

University of Bonn researchers are studying the lifespan and growth patterns of early mammals What distinguishes the growth and development patterns of early mammals of the Jurassic period? This is the question jointly investigated by researchers of Queen Mary University of London and the University of Bonn.

Geological studies of a drill core combined with computer models show that large ice sheets first formed only in East Antarctica The glaciation of the Antarctic began approximately 34 million years ago, but the initial phase of glaciation did not encompass the entire continent - as previously assumed.

Mast cells trap and use living neutrophils during allergic reactions Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation.

Research team including Göttingen University develops high-resolution fluorescence microscope What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers from the Universities of Göttingen and Oxford, in collaboration with the University Medical Center Göttingen (UMG), have succeeded in developing a microscope with resolutions better than five nanometres (five billionths of a metre).

The brain is constantly storing new experiences that it has to integrate into the jumble of existing memories. Surprisingly, it does not overwrite previous memory traces in the process. The first day of school: entering the classroom for the first time, the excited feeling in your stomach and the joy of having a school bag - these are all typical examples of memories from our episodic memory.

In young planetary systems, gas giants form more efficiently and faster than previously assumed as shown by new computer simulations. Ring-shaped perturbations in disks of gas and dust orbiting young stars can trigger the formation of several gas giants, as researchers from the ORIGINS Cluster of Excellence, Ludwig-Maximilians-Universität in Munich and the Max Planck Institute for Solar System Research (MPS) in Göttingen report in the current issue of the journal Astronomy and Astrophysics.

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the University of Münster have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils.

Researchers from the University of Münster analysed 202 fragments At the beginning of this year, on 21 January, a huge fireball was visible over the German state of Brandenburg. It was the result of a small celestial body entering the Earth's atmosphere, bursting and falling to the ground in numerous fragments near Ribbeck in the Havelland.

Research team led by Göttingen University expands the applications of oxygen isotope measurements   Measuring temperatures from Earth's past is important for understanding the development of its climate. Ancient ocean temperatures are most commonly reconstructed by analysing the ratio of different oxygen atoms in the calcium carbonate remains of fossils.
