With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown between theory and experiment that may uncover new particles or forces.

Random telegraph noise (RTN) in semiconductors is typically caused by two-state defects. Two-dimensional (2D) van der Waals (vdW) layered magnetic materials are expected to exhibit large fluctuations due to long-range Coulomb interaction; importantly, which could be controlled by a voltage compared to 3D counterparts having large charge screening. Researchers reported electrically tunable magnetic fluctuations and RTN signal in multilayered vanadium-doped tungsten diselenide (WSe2) by using vertical magnetic tunneling junction devices. They identified bistable magnetic states in the 1/f2 RTNs in noise spectroscopy, which can be further utilized for switching devices via voltage polarity.

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.

Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.

Researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior of the material, rather than at the edges, as scientists had long assumed.

New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and many other domains of radar applications. It addresses a nine decades-old problem that requires scientists and engineers to sacrifice detail and resolution for observation distance -- underwater, underground, and in the air.

A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations show that the up quark is more symmetrically distributed and spread over a smaller distance than the down quark.

Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.
