The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes - microscopically small tubular compounds that emit light in the near-infrared - chemists and materials scientists at Heidelberg University led by Jana Zaumseil have now demonstrated a new reaction pathway to enable such defect control.

Losing weight through exercise
Losing weight through exercise
Why physical activity entices you to eat more - and how to fight it Around two thirds of men and half of women in Germany* are overweight, according to statistics collected by the German Obesity Society. Concurrently millions of people want to lose weight. One way to do this is exercising. But what influence does sport have on (direct) eating habits? Scientists at the Technical University of Munich (TUM) and the University of Nebraska (USA) have now investigated this question for the first time.

Asteroid crater on Earth provides clues about Martian craters
Asteroid crater on Earth provides clues about Martian craters
Research team led by the University of Göttingen discovers crater floor sagging from bowl-shaped volcanic ash layer The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on the rim of the basin, the crater fill is mainly formed by stratified clay deposits.

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.

The egg in the X-ray beam
A team of scientists has been using DESY's X-ray source PETRA III to analyze the structural changes that take place in an egg when you cook it. The work reveals how the proteins in the white of a chicken egg unfold and cross-link with each other to form a solid structure when heated. Their innovative method can be of interest to the food industry as well as to the broad field of research surrounding protein analysis.

Researchers first to link silicon atoms on surfaces
Researchers first to link silicon atoms on surfaces
Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials. So-called conjugated polymers are candidates. These organic macromolecules have semi-conductor properties, i.e. they can conduct electricity under certain conditions.

Strong weld joints for aerospace applications
Strong weld joints for aerospace applications
Measurements at the Research Neutron Source help with the development of intelligent welding equipment When a rocket is launched, the weld seams on the enormous fuel tanks must withstand immense forces. To produce joints with the necessary strength, a process known as "friction stir welding" is used.

Apes constantly reinvent the wheel
Great apes do not pass on their behavior to the next generation. Unlike humans, they do not copy the specific knowledge of those around them, instead learning it anew in each generation. This is shown in a study by Dr. Alba Motes-Rodrigo and Dr. Claudio Tennie of the "Tools and Culture in Early Hominins" research group at the University of Tübingen.

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.

Researchers develop hybrid handbike for the disabled Unlike the classic bicycle, the handbike is powered by the arms and is one of the most popular pieces of sports equipment among paraplegics. But there's one major drawback: While on the go with a handbike, the rider has no wheelchair handy, for example to go shopping or go to a restroom.

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.

Hypnosis is beneficial for surgical patients
Meta-analysis reveals: Hypnosis relieves pain, reduces mental distress and promotes recovery after surgery Hypnosis relieves pain, reduces mental distress and promotes recovery after surgical interventions - this has been shown in a meta-analysis recently published in Clinical Psychology Review. By evaluating 50 individual studies with over 4000 patients, scientists from Jena and Leipzig examined the efficacy of hypnosis in the context of surgical interventions.

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.
