The ancient Egyptians, as described in the Ebers Papyrus, already knew that palpation -feeling for hardened lumps - can help diagnose breast cancer. Palpation is still an important element in early screening for breast cancer. On the other hand, measurements on individual cancer cells show that they are softer than the healthy epithelial cells from which they stem, which probably makes them better able to metastasise in dense human tissue.

Göttingen researchers use laser to reveal that the inside of living cells softens and fluidifies when dividing Living cells are the basic building blocks of all organisms. We, as humans, are essentially a collection of trillions of living cells: and all these cells emerge from a single fertilized egg.

Comparatively, neutrons detect most defects in 3D printed components In the manufacture of turbines conventional processes often reach their limits. Therefore, additive manufacturing is increasingly used to produce complex, curved components with intricate structures. A research team from the Technical University of Munich (TUM) has now examined common methods used to locate defects inside components.

Researchers at Göttingen University use computer simulation to investigate models of living systems Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, demonstrating fascinating properties such as adapting to their environment or repairing themselves.

Date: April 26, 2021, No. DFG approves new priority program coordinated by the University of Stuttgart Design Assistants in Mechanics and Dynamics are the topic of a new priority program (PP) of the German Research Foundation (DFG) that aims to bring more artificial intelligence (AI) into the design process of technical systems.

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.

Computational model of the lung could significantly reduce the number of deaths from Covid-19 and ARDS Computer model enables protective ventilation The use of mechanical ventilation can save lives - and not just for COVID-19 patients who develop severe respiratory problems. But at the same time, the ventilation pressure puts immense stress on delicate lung tissue.

TUM, Oerlikon and Linde develop high-strength lightweight aluminum-based alloy New research alliance for additive manufacturing Together with the Swiss technology group Oerlikon and the industrial gas manufacturer Linde, the Technical University of Munich (TUM) has entered into a research alliance for additive manufacturing (AM).

When an organism develops, masses of cells combine to form different types of tissue, all of which have different functions. In order to be able to form and to move, a cell needs to generate mechanical forces by remodelling its cytoskeleton, which consists of various filaments. Filaments from the actin protein, for example, contract and expand.

A system's state is characterised as entangled or quantum correlated if two or more particles cannot be described as a combination of separate, independent states but only as a whole. Researchers at the Kirchhoff Institute for Physics of Heidelberg University recently succeeded in verifying so-called non-local quantum correlations between ultracold clouds of rubidium atoms.

The world's most powerful aerospace gearbox will go into service in 2025: It is part of the Rolls-Royce UltraFan design and will transfer up to 100,000 hp. In a project supported by the German federal government, scientists at the Technical University of Munich (TUM) are investigating how the gearbox's properties vary according to size and how they can be optimized.

Research news The almost complete silence of the motors used in electric cars may pose a hazard to inattentive pedestrians. As a result, starting in summer 2019 all new electric and hybrid vehicles will have to be equipped with an acoustic warning system. Psychoacousticians at the Technical University of Munich (TUM) are developing the corresponding sounds.

Research news Childhood obesity is often attributed to a lack of exercise. So what about sports among elementary school students' A team from the Technical University of Munich (TUM) pursued this question and collected the results of fitness tests for first-year students over a period of one decade. Their study shows that students did not lose their strength.

Research news More than 125 years ago, Otto Lilienthal laid the foundation for modern aviation with his innovative gliding apparatus, the "Normal Segelapparat". Only four specimens of the gliding apparatus have survived to this day, one of them at home in Deutsches Museum in Munich. Computer tomography investigations carried out by researchers at the Technical University of Munich (TUM) in collaboration with Airbus have for the first time provided a glimpse into the inner workings of the construction design.

Research news After a stroke, many people are unable to successfully perform basic hand movements in everyday life. The reason are symptoms of hemiparesis resulting from damage to the brain. These very frequently affect fine motor skills. A team from the Technical University of Munich (TUM) is now paving the way to better diagnosis and more targeted therapy.

Not only muscle cells, but also all other cell types continually generate forces in the human body. An interdisciplinary cooperation of biologists and physicists including Heidelberg researcher Ulrich Schwarz now succeeded in performing high-resolution measurements of cell forces using light to switch them on and off in a controlled manner.

Scientists from Freie Universität, University of Innsbruck, University of Cologne, and University of Sydney Developed New Method ' 123/2017 from May 17, 2017 Together with colleagues from Germany, Austria, and Australia, scientists from Freie Universität Berlin developed a new method for investigating quantum mechanical processes, and they tested their method experimentally.

Heidelberg Neuroscientists have identified a critical regulator for blood vessel growth in the developing embryonic spinal cord. The research group under the direction of Dr Carmen Ruiz de Almodóvar of the Heidelberg University Biochemistry Center discovered that special nerve cells known as motor neurons control this process.

Based on a study of the optical properties of novel ultrathin semiconductors, LMU researchers have developed a method for rapid and efficient characterization of these materials. Chemical compounds based on elements that belong to the so-called transition metals can be processed to yield atomically thin two-dimensional crystals consisting of a monolayer of the composite in question.

Living cells must alter their external form actively, otherwise functions like cell division would not be possible. At the Technical University of Munich (TUM) the biophysicist Professor Andreas Bausch and his team have developed a synthetic cell model to investigate the fundamental principles of the underlying cellular mechanics.
