Tumors actively prevent the formation of immune responses by so-called cytotoxic T cells, which are essential in combating cancer. Researchers at the Technical University of Munich (TUM) and the Ludwig-Maximilians-Universität München (LMU) Hospital have now uncovered for the first time how this exactly happens. The study in the journal Nature provides rationales for new cancer immunotherapies and could make existing treatments more effective. A second paper in Nature confirms the findings. In cancer, tumors often impair the body's immune response. For example, they can prevent immune cells from perceiving cancer cells as a threat or render them inactive. Immunotherapies aim ...

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called “bands” and the space between them, the forbidden energies, are known as “band-gaps”. Both of them together constitute the “band structure” of the material, which is a unique characteristic of each specific material. When physicists plot the band structure, they usually see that the resulting curves resemble mountains and valleys. In fact, the technical term for a local energy maximum or minimum in the bands is called a “valley”, and the field which studies and exploits how electrons in the material ...

As our battle against cancer rages on, the quest for more sophisticated and realistic models to study tumor development has never been more critical. Until now, research has relied on animal models and simplified cell culture methods, which are valuable but cannot fully capture the complex interplay of factors involved in tumor development. Even newer, more advanced models for studying cancer, such as organoids – tiny, lab-grown versions of organs – do not faithfully replicate the cell behaviors and tissue architectures seen in actual tumors. This gap has significantly hindered our understanding ...

Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building quantum systems. In the case of quantum networks, color centers in diamond, which are defects intentionally added to a diamond crystal, are crucial for generating and maintaining stable quantum states over long distances. When stimulated by external light, these color centers in diamond emit photons carrying information about their internal electronic states, especially the spin states. The interaction between the emitted photons and the ...

A new study, led by the University of Oxford and MIT, has recovered a 3.7-billion-year-old record of Earth’s magnetic field, and found that it appears remarkably similar to the field surrounding Earth today. The findings have been published today in the Journal of Geophysical Research. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged particles emitted by the Sun (the ‘solar wind’). But up to now, there has been no reliable date for when the modern magnetic field was first established.    In the new study, the researchers examined ...

DURHAM, N.C. – The unique circumstances arising from the COVID-19 pandemic altered a long-held convention that doctors provide care regardless of personal risk. In a study assessing doctors’ tolerance for refusing care to COVID-19 patients, Duke Health researchers identified a growing acceptance to withhold care because of safety concerns.  “All the papers throughout history have shown that physicians broadly believed they should treat infectious disease patients,” said the study’s lead author, Braylee Grisel, a fourth-year student at Duke University ...

Estuaries — where freshwater rivers meet the salty sea — are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, “blue” osmotic energy. Researchers in ACS Energy Letters report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations. Osmotic energy can be generated anywhere salt gradients are ...

In February, OpenAI released videos created by its generative artificial intelligence program Sora. The strikingly realistic content, produced via simple text prompts, is the latest breakthrough for companies demonstrating the capabilities of AI technology. It also raised concerns about generative AI’s potential to enable the creation of misleading and deceiving content on a massive scale. According to new research from Drexel University, current methods for detecting manipulated digital media will not be effective against AI-generated video; but a machine-learning approach could be the key to unmasking these synthetic creations. In a paper accepted ...

PULLMAN, Wash. – Political conservatives who watched a documentary on Syrian refugees with a virtual reality headset had far more sympathy for the people depicted in the film than those who viewed the same film on a two-dimensional computer screen.  Higher sympathy levels among the conservatives who watched the VR version of the documentary, “Clouds over Sidra,” resulted in a greater willingness to donate to the crisis, according to a study on the research published in New Media & Society.   Liberal participants in the study reported high levels of sympathy and ...

Setting the stage for a new era of immersive displays, researchers are one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images, according to a study led by Princeton University researchers. Holographic images have real depth because they are three dimensional, whereas monitors merely simulate depth on a 2D screen. Because we see in three dimensions, holographic images could be integrated seamlessly into our normal view of the everyday world. The result is a virtual and augmented reality display that has the potential to be truly immersive, the kind where you can move your head ...
