Crystals may help reveal hidden Kilauea Volcano behavior — ScienceDaily

Scientists striving to understand how and when volcanoes might erupt face a challenge: many of the processes take place deep underground in lava tubes churning with dangerous molten Earth. Upon eruption, any subterranean markers that could have offered clues leading up to a blast are often destroyed. But by leveraging observations of tiny crystals of […]

Hidden structure found in essential metabolic machinery

Membrane-separated compartments are visible inside the peroxisomes of 4-day-old Arabidopsis thaliana plant cells in this image from a confocal microscope. The cells were genetically modified to produce fluorescent proteins in both the membranes (green) and lumen (magenta) of the peroxisomes.

A Cretaceous-age, crow-sized bird from Madagascar would have sliced its way through the air wielding a large, blade-like beak and offers important new insights on the evolution of face and beak shape in the […]

Plant evolves to stay hidden from harvesting humans — ScienceDaily

A plant used in traditional Chinese medicine has evolved to become less visible to humans, new research shows. Scientists found that Fritillaria delavayi plants, which live on rocky slopes of China’s Hengduan mountains, match their backgrounds most closely in areas where they are heavily harvested. This suggests humans are “driving” evolution of this species into […]

Hidden world of bacteria and fungi discovered on Leonardo da Vinci’s drawings

Leonardo da Vinci is famous for his elaborate, nuanced artworks and advanced technological ideas. But new research has revealed another level of complexity to his drawings: a hidden world of tiny life-forms on his artwork. The findings, the researchers said, could help build a microbiome “catalogue” for artwork. Each of the pieces had a unique […]

Germanium telluride’s hidden properties at the nanoscale revealed

The Fermi surface of multidomain GeTe (111) bulk single crystal measured with high-resolution angle-resolved photoemission at BESSY II. Credit: HZB Germanium telluride (GeTe) is known as a ferrolectric Rashba semiconductor with a number of interesting properties. The crystals consist of nanodomains, whose ferrolectric polarization can be switched by external electric fields. Because of the so-called […]

Has the hidden matter of the universe been discovered? — ScienceDaily

Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d’Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis […]

Germanium telluride’s hidden properties at the nanoscale revealed — ScienceDaily

Germanium telluride (GeTe) is known as a ferrolectric Rashba semiconductor with a number of interesting properties. The crystals consist of nanodomains, whose ferrolectric polarization can be switched by external electric fields. Because of the so-called Rashba effect, this ferroelectricity can also be used to switch electron spins within each domain. Germanium telluride is therefore an […]
