Researchers at the University of Bristol found that plant eaters diversified quickly after mass extinctions to eat different kinds of plants, and the ones that were able to chew harsher materials, which reflected the drying conditions of the late Triassic, became the most successful. These tougher herbivores included some of the first dinosaurs.

The international scientific community agrees that the latest findings of an FAU research team will revolutionise the entire chemistry of magnesium. The research team have discovered magnesium, which usually has a double positive charge in chemical compounds, in the elemental zero-oxidation state. They have published their ground-breaking findings in the journal Nature.

High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that hydrogen can bond strongly with iron in extreme conditions. This explains the presence of significant amounts of hydrogen in the Earth's core that arrived as water from bombardments billions of years ago.

A group of scientists at Nagoya University, Japan, have developed an incredibly versatile DNA fluorescent dye, named 'Kakshine' after a former NU student of its members, Dr Kakishi Uno, but it also means to make the nucleus shine brightly, since the nucleus is pronounced 'Kaku' in Japanese.

Organizing functional objects in a complex, sophisticated architecture at the nanoscale can yield hybrid materials that tremendously outperform their solo objects, offering exciting routes towards a spectrum of applications. The development in synthetic chemistry over past decades has enabled a library of hybrid nanostructures, such as core-shell, patchy, dimer, and hierarchical/branched ones.

Nevertheless, the material combinations of these non-van der Waals solids are largely limited by the rule of lattice-matched epitaxy.

Today, the rocks of the Hanna Formation in south-central Wyoming are hundreds of miles away from the nearest ocean. But around 58 million years ago, Wyoming was oceanfront property, with large hippo-like mammals traipsing through nearshore lagoons.

What The Study Did: This survey study examined differences between male and female physicians in the use of social media and reported career and professional benefits.

Authors: Shikha Jain, M.D., of the University of Illinois at Chicago, is the corresponding author.

Cooperation as a successful strategy has evolved in both nature and human society, but understanding its emergence can be a difficult task. Researchers have to abstract interactions between individuals into mathematical formulas to be able to create a model that can be used for predictions and simulations.

New research led by the University of Kent has found that adolescents and older adults pay less attention to social cues in real-world interactions than young adults.

The findings published by Nature Human Behaviour show that social attention undergoes age-related change, which has potential implications for how successfully we can interpret social interactions in daily life and throughout the lifespan.

Numerous compelling evidences from astroparticle physics and cosmology indicate that the major matter component in the Universe is dark matter, accounting for about 85% with the remaining 15% is the ordinary matter. Nevertheless, people still know little about the dark matter, including its mass and other properties. Many models predict dark matter particles could couple to ordinary particle at weak interaction level, so it is possible to capture the signal of dark matter particle in the direct detection experiment.

As we move through the world, what we see is seamlessly integrated with our memory of the broader spatial environment. How does the brain accomplish this feat? A new study from Dartmouth College reveals that three regions of the brain in the posterior cerebral cortex, which the researchers call "place-memory areas," form a link between the brain's perceptual and memory systems. The findings are published in Nature Communications.

Optical imaging systems have been playing an essential role in scientific discovery and societal progress for several centuries. For more than 150 years scientists and engineers have used aberration theory to describe and quantify the deviation of light rays from ideal focusing in an imaging system. Until recently most of these imaging systems included spherical and aspherical refractive lenses or reflective mirrors or a combination of both.

The relevance for radiology applications is probably the most known advantage of X-ray beams (keV energies) with respect to visible radiation (eV energies) and can be traced back to their superior penetration depth. On a more fundamental ground, however, the relevance of this photon energy range relies on the capability of probing inner shell electrons (as they have comparable binding energies) and mapping molecular structures on the atomic-scale (as typical interatomic spacings are comparable to X-ray wavelengths).

The Indian public blamed foreigners, minority groups and doctors for the rapid spread of COVID-19 across the country during the first wave, due to misinformation, rumour and long-held discriminatory beliefs, according to an international study led by Monash University.

This resulted in people refusing to get tested for fear of humiliation or public reprisals, which included attacks on Muslims and health care workers.

Compared with the superresolution microscopy that bases on squeezing the point spread function in the spatial domain, the superresolution microscopy that broadens the detection range in the spatial frequency domain through the spatial-frequency-shift (SFS) effect shows intriguing advantages including large field of view, high speed, and good modularity, owing to its wide-field picture acquisition process and universal implementation without using special fluorophores labeling.
