New research into the anatomy of blue sharks ( Prionace glauca ) reveals a unique nanostructure in their skin that produces their iconic blue coloration, but intriguingly, also suggests a potential capacity for color change.
A 2.35-billion-year-old meteorite with a unique chemical signature, found in Africa in 2023, plugs a major gap in our understanding of the Moon's volcanic history.
A University of Portsmouth student has discovered a new species of prehistoric mammal dating back 145 million years to the Berriasian age, providing fresh insights into the diversity of early mammals that lived alongside dinosaurs.
In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic-crystal surface-emitting laser emitting at room temperature and an eye-safe wavelength. Their findings, published in IEEE Photonics Journal , improve upon current laser design and open new avenues for defense applications.
A fascinating glimpse into how a solar system like our own is born has been revealed with the detection of planet-forming 'pebbles' around two young stars.
Archaeologists from the University of Houston working at Caracol in Belize, Central America have uncovered the tomb of Te K'ab Chaak, the first ruler of this ancient Maya city and the founder of its royal dynasty. Now in ruins, this metropolis was a major political player in Maya history, dominating the southern part of the Yucatan Peninsula from 560 through 680 AD before its abandonment by 900 AD.
Focusing solely on achieving weight loss for people with a high body mass index (BMI) may do more harm than good, argue experts in The BMJ .
Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers to solve a longstanding problem in the materials science and physics worlds known as the polaron problem, giving scientists and engineers a way to predict how electrons will flow in certain materials, both conventional and quantum.
Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cell in the human brain according to the latest calculations. These cell types vary in their function, in the number and length of their cellular appendages, and in their interconnections. They emit different neurotransmitters into our synapses and, depending on the region of the brain - for example, the cerebral cortex or the midbrain - d...
A new kind of cosmic object could help solve one of the universe's greatest mysteries: dark matter.
