The fossil bird that choked to death on rocks, and no one knows why

The fossil bird that choked to death on rocks, and no one knows why

A fossil only tells part of the story. When an animal's body is preserved as a fossil, there are often pieces missing, and even a perfectly preserved body doesn't tell the whole story of how that animal behaved, how it lived, and how it ultimately died.

Extremely rare 'dinosaur mummy' makes its way to Minnesota for study

Extremely rare 'dinosaur mummy' makes its way to Minnesota for study

The fossil called "Medusa" could be a dinosaur mummy—the remains of an Edmontosaurus about 66 million years old that researchers believe contains a significant amount of skin and tendon tissue.

Probing the existence of a fifth force via neutron star cooling

Probing the existence of a fifth force via neutron star cooling

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into space.

Physicists provide key mass data for determining X-ray burst reaction rate

Physicists provide key mass data for determining X-ray burst reaction rate

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27. These precise measurements provide crucial information for determining the nuclear reaction rate during X-ray bursts, advancing our understanding of how elements are synthesized under such extreme conditions.

Yeast cell factory converts methanol into L-lactate for biodegradable plastics

Yeast cell factory converts methanol into L-lactate for biodegradable plastics

Methanol is an ideal feedstock for bio-manufacturing. Converting it into lactate, a monomer for biodegradable plastic, offers a promising strategy for addressing the challenge of white pollution. However, it remains difficult to engineer microbes to produce lactate from methanol due to methanol toxicity and strong competition between product synthesis and cell growth.

Shaping quantum light unlocks new possibilities for future technologies

Shaping quantum light unlocks new possibilities for future technologies

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and time to create high-dimensional and multidimensional quantum states. Their work highlights how structured photons—light whose spatial, temporal or spectral properties are deliberately shaped—offer new pathways for high-capacity quantum communication and advanced quantum technologies.

X-ray spikes reveal electron beam size

X-ray spikes reveal electron beam size

While synchrotron radiation is often thought of as "stable," the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about the electron beam that produces the X-rays.

Decoding dark matter's imprint on black-hole gravitational waves

Decoding dark matter's imprint on black-hole gravitational waves

A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on Einstein's theory of general relativity, that tracks in detail how a black hole interacts with the surrounding matter.

The hexatic phase: Ultra-thin 2D materials in a state between solid and liquid observed for the first time

The hexatic phase: Ultra-thin 2D materials in a state between solid and liquid observed for the first time

When ice melts into water, it happens quickly, with the transition from solid to liquid being immediate. However, very thin materials do not adhere to these rules. Instead, an unusual state between solid and liquid arises: the hexatic phase. Researchers at the University of Vienna have now succeeded in directly observing this exotic phase in an atomically thin crystal.

Chameleon-like nanomaterial can adapt its color to mechanical strain

Chameleon-like nanomaterial can adapt its color to mechanical strain

Inspired by the Japanese art of kirigami, a team of scientists from the University of Amsterdam have developed a material that can reflect different colors of light, depending on how it is stretched. The results were recently published in the journal ACS Photonics.
