New research identifies ctenophores as the first animals to diverge, reshaping our understanding of evolution and key biological traits.
CycloTech’s all-electric flying vehicle is capable of controlled descents even in stormy weather with motors similar to those used for tug boats.
Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle and condensed matter theories, after proving that any non-invertible symmetry operation in theoretical physics is a quantum operation. The study was published in Physical Review Letters as an Editors’ Suggestion on November 6.
In physics, symmetry provides an important clue to the properties of a theory. For example, if the N-poles in a magnetic field are replaced by the S-poles, and the S-poles by the N-poles all at once, the forces on objects and the energy stored in the magnetic field remain the same, even though the direction of the magnetic field has now become reversed. This is because the equations describing the magnetic field are symmetric with respect to the operation of swapping the N and S poles.
Over the past few years, the concept of symmetries has received generalization in various directions in the theoretical study of particle physics and condensed matter physics, becoming an active area of research. One such generalization is non-invertible symmetry. The operation of conventional symmetries is always invertible. There exists a reverse operation to undo it. Non-invertible symmetry, on the other hand, allows certain non-invertibility in such symmetry operations.
The Space Force’s 45th Weather Squadron pegs the odds of “go for launch” weather at 85%. Chief meteorological risks include thick cloud layers and liftoff winds, coupled with a low-to-moderate risk of upper-level wind shear.

In a commercial warehouse overlooking the ocean in New Zealand’s capital Wellington, a startup is trying to recreate the power of a star on Earth using an unconventional “inside out” reactor with a powerful levitating magnet at its core.
Its aim is to produce nuclear fusion, a near-limitless form of clean energy generated by the exact opposite reaction the world’s current nuclear energy is based on — instead of splitting atoms, nuclear fusion sets out to fuse them together, resulting in a powerful burst of energy that can be achieved using the most abundant element in the universe: hydrogen.
Earlier this month, OpenStar Technologies announced it had managed to create superheated plasma at temperatures of around 300,000 degrees Celsius, or 540,000 degrees Fahrenheit — one necessary step on a long path toward producing fusion energy.
In the study of temporal mechanics, we have to venture beyond the confines of traditional objective science to incorporate the profound role of consciousness in shaping our understanding of time. The evidence and theories discussed throughout my upcoming paper (to be released as a Kindle eBook) suggest that the flow of time is not simply a physical phenomenon dictated by the laws of thermodynamics or the spacetime continuum, but rather a deeply psychological one, intertwined with consciousness itself. Time, as we experience it, emerges from our awareness of ongoing change—a continuous psychological construct that weaves our perceptions into a coherent narrative of past, present, and future.
The implications of this perspective are far-reaching. If the flow of time is indeed a function of consciousness, then time cannot be fully understood without accounting for the observer—the conscious entity whose perception of change gives rise to the experience of time. This challenges the classical notion of time as a separate, objective entity and places consciousness as a central player in the multidimensional matrix of reality.

Emotional body odors may have the potential to enhance the anxiety-reducing effects of mindfulness. This is shown by a pilot study published in the Journal of Affective Disorders, co-authored by researchers from Karolinska Institutet.
Body odors can serve as a means of social communication. Body odors, such as sweat, contain a cocktail of chemical processes (so-called chemosignals), which in turn are influenced by a person’s emotional state. Studies indicate that individuals exposed to chemosignals from a person in a particular emotional state, such as fear or happiness, exhibit a certain replication of this state. This replication occurs unconsciously and has most often been observed through different physiological tests.
As most studies in this area have involved healthy subjects, the overall goal of this project was to study the potential benefit of chemosignals for individuals with psychiatric symptoms. The purpose of this study was therefore to investigate whether emotional body odors can enhance the benefits of a mindfulness-based intervention for individuals with social anxiety or depression.
Artificial intelligence has the potential to improve the analysis of medical image data. For example, algorithms based on deep learning can determine the location and size of tumors. This is the result of AutoPET, an international competition in medical image analysis, where researchers of Karlsruhe Institute of Technology (KIT) were ranked fifth.
The seven best autoPET teams report in the journal Nature Machine Intelligence on how algorithms can detect tumor lesions in positron emission tomography (PET) and computed tomography (CT).
Imaging techniques play a key role in the diagnosis of cancer. Precisely determining the location, size, and type of tumor is essential for choosing the right therapy. The most important imaging techniques include positron emission tomography (PET) and computer tomography (CT).
Colorectal cancer (CRC) remains one of the most clinically challenging malignancies facing our public health system. CRC accounts for the second and third most common cancer in males and females, respectively. In addition, CRC represents one of the most deadly cancers, expected to result in over 50,000 mortalities in 2024.
Hereditary colorectal cancer (HCRC) occurs when a parent passes a cancer gene to a child. Unfortunately, we have not identified a single gene that causes the disease. Hereditary CRC syndromes, such as hereditary non-polyposis colorectal cancer (HNPCC; also known as Lynch syndrome) and familial adenomatous polyposis (FAP), describe a group of genetic diseases that confer a high risk of developing CRC. As our knowledge has expanded, we have learned about a growing number of genetic variants in the genes that predispose carriers to CRC. However, the precise role of some variants in the development of CRC cancer remains unclear. Uncovering more information about these variants, called variants of uncertain significance.
