Is it Possible to Slow Down Age-Related Memory Loss?
A team of researchers from Berlin, Dortmund, and Graz are investigating how the substance spermidine can protect aging brain cells. No 062/2021 from Apr 13, 2021 According to a recent study, age-related memory loss may be preventable. Researchers from Freie Universität Berlin, the NeuroCure Cluster of Excellence, the Leibniz-Institut für Analytische Wissenschaften (ISAS) in Dortmund, and the University of Graz found that the substance spermidine - something that is present in all human cells - can protect the mitochondria found in aging brain cells.

Junctions between three cells enable the transport of substances
Researchers at the University of Münster discover how cell contacts are dynamically remodelled during egg development in fruit flies / Study published in "Developmental Cell" Within multicellular organisms, cells build connections with each other forming cell layers that cover the surfaces of tissues and organs and separate structures in the body.

Using AI to Diagnose Neurological Diseases Based on Motor Impairment
New Heidelberg approach: analysing movement patterns through machine learning The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications.

Neanderthal Ancestry Identifies Oldest Modern Human Genome
In an article published in Nature Ecology & Evolution , an international team of researchers sequence the genome of an almost complete skull first discovered in ZlatÃoe Kůň, Czechia in the early 1950s and now stored in the National Museum in Prague. The segments of Neanderthal DNA in its genome were longer than those of the Ust-Ishim individual from Siberia, the previous oldest modern human sequenced, suggesting modern humans lived in the heart of Europe more than 45,000 years ago.

Analysis of ancient bones reveals Stone Age diet details
Fish was not on the menu of the hunter-gatherers of southern Europe 27,000 years ago. Surprisingly, people on the Iberian Peninsula in the Late Gravettian period mostly ate plants and land animals such as rabbits, deer and horses. An international team of researchers has been able to determine this for the first time on the basis of an isotope study of human fossils from the Serinyà caves in Catalonia.

A more effective production of therapeutic antibodies
A more effective production of therapeutic antibodies
Immunoglobulins are antibodies that are generated by the immune system in answer to the sudden emergence of macromolecules. For example, these might be on the cell surface of bacteria that have infiltrated the body, or they are found in abnormal somatic cells. These play an important role in the identification and suppression of infections, such as Hepatitis A/B or Rabies, and in controlling cancer cells.

How activated T cells destroy the liver
How activated T cells destroy the liver
Auto-aggressive immune cells cause fatty liver hepatitis Non-alcoholic steatohepatitis (NASH), often called 'fatty liver hepatitis', can lead to serious liver damage and liver cancer. A team of researchers at the Technical University of Munich (TUM) has discovered that this condition is caused by cells that attack healthy tissue - a phenomenon known as auto-aggression.

How Grasslands respond to climate change
How Grasslands respond to climate change
Effects of CO2 increase were already apparent in the past century The rise in atmospheric carbon dioxide concentration and concurrent climate change has led to yield reductions of grass-rich grassland vegetation in the past century. This observation was made by researchers at the Technical University of Munich (TUM) who, working jointly with colleagues from Rothamsted (U.K.), conducted a study on the world's oldest permanent ecological experiment there.

Cephalopods: Older Than Was Thought?
Cephalopods: Older Than Was Thought?
Fossil find from Canada could rewrite the evolutionary history of invertebrate organisms The possibly oldest cephalopods in the earth's history stem from the Avalon Peninsula in Newfoundland (Canada). They were discovered by earth scientists from Heidelberg University. The 522 million-year-old fossils could turn out to be the first known form of these highly evolved invertebrate organisms, whose living descendants today include species such as the cuttlefish, octopus and nautilus.

Where and how plants detect the nutrient potassium
Where and how plants detect the nutrient potassium
Newly discovered group of cells in the root tip reacts to potassium deficiency and directs signalling pathways mediating plant adaptation Potassium is an essential nutrient for all living things. Plants need it in large quantities, especially for growth and in order to withstand stress better. For this reason, they absorb large quantities of potassium from the soil.

Cells On the Rack
Device the size of a few micrometres provides insight into how cells respond to mechanical stress Cell behaviour - for instance during wound healing - is controlled by biological factors and chemical substances, with physical forces such as pressure or tension also playing a role.

Eagle Shark Flew Through the Ocean 93 Million Years Ago
Eagle Shark Flew Through the Ocean 93 Million Years Ago
New insights into the history of shark evolution are offered by the fossil of a hitherto unknown primeval fish. It was discovered in a quarry in Mexico by a European-Mexican paleontological team, of which Wolfgang Stinnesbeck from Heidelberg University is a member. The find is a type of shark from the Cretaceous Period.

How gamblers plan their actions to maximize rewards
A study in biological psychology has shown that habitual gamblers use strategies during reinforcement learning that differ from those of the control group. This difference could be caused by changes in the dopamine system that influence strategic planning. In their pursuit of maximum reward, people suffering from gambling disorder rely less on exploring new but potentially better strategies, and more on proven courses of action that have already led to success in the past.

Cancer therapy: How our cells are becoming resistant to medication
New study gives hope for more effective therapies Human cells are constantly changing shape. Biologists know that these morphological changes reflect changes in a cell's function but our ability to understand the meaning behind a cell's shape has, to date, been limited. In their new study Rune Linding from Humboldt-Universität zu Berlin (HU) and his colleagues have utilized artificial intelligence to learn, and interpret, changes in the morphology of cancer cells in order to understand how these cells are becoming resistant to cancer medication.

The astonishing self-organization skills of the brain
A team of researchers from Tübingen and Israel uncovers how brain structures can maintain function and stable dynamics even in unusual conditions. Their results might lay the foundations for better understanding and treating conditions like epilepsy and autism. The neurons in our brains are connected with each other, forming small functional units called neural circuits.

New proteins
New proteins "out of nothing"
Proteins are the key component in all modern forms of life. Haemoglobin, for example, transports the oxygen in our blood; photosynthesis proteins in the leaves of plants convert sunlight into energy; and fungal enzymes help us to brew beer and bake bread. Researchers have long been examining the question of how proteins mutate or come into existence in the course of millennia.
