The quantum nature of interactions between elementary particles allows drawing non-trivial conclusions even from processes as simple as elastic scattering. The ATLAS experiment at the LHC accelerator reports the measurement of fundamental properties of strong interactions between protons at ultra-high energies.   The physics of billiard ball collisions is taught from early school years. In a good approximation, these collisions are elastic, where both momentum and energy are conserved. The scattering angle depends on how central the collision was (this is often quantified by the impact parameter value – the distance between the centres of ...

With just a few clicks of a mouse, you can purchase your very own redtail garra, a type of fish that feeds on algae. Information about the fish’s biology, however, is much less easily obtained. That’s because redtail garra, although popular in the aquarium trade since the early 2000s, has until now been unknown to science. Researchers were peripherally aware of the fish’s existence, but “discovering” a new species requires scientific description based on specimens collected in their natural ...

PHILADELPHIA (July 10, 2023) – A unique collaborative study on hospital clinician wellbeing by teams at 60 of the nation’s best hospitals, defined by Magnet Hospital Recognition, was published today in JAMA Health Forum. The study found that physicians and nurses, even at hospitals known to be good places to work, experienced adverse outcomes during the pandemic and want hospital management to make significant improvements in their work environments and in patient safety. The solutions to high hospital clinician burnout and turnover, they say, are not resilience training ...

Two drugs commonly used to treat inflammatory diseases such as rheumatoid arthritis and psoriasis did not shorten recovery time for patients hospitalized with severe COVID-19 but did reduce the likelihood of death when compared with standard care alone, according to a national study led by Washington University School of Medicine in St. Louis. The study was funded by the Biomedical Advanced Research and Development Authority (BARDA) of the Administration for Strategic Preparedness and Response within the U.S. Department of Health and Human Services (HHS). The study was coordinated by the National Center for Advancing Translational Sciences (NCATS) of the National Institutes of Health ...

Movement in the Earth’s tectonic plates indirectly triggers bursts of biodiversity in 36‑million-year cycles by forcing sea levels to rise and fall, new research has shown. Researchers including geoscientists at the University of Sydney believe these geologically driven cycles of sea level changes have a significant impact on the diversity of marine species, going back at least 250 million years. As water levels rise and fall, different habitats on the continental shelves and in shallow seas expand and contract, ...

Silence might not be deafening but it’s something that literally can be heard, concludes a team of philosophers and psychologists who used auditory illusions to reveal how moments of silence distort people’s perception of time. The findings address the debate of whether people can hear more than sounds, which has puzzled philosophers for centuries. “We typically think of our sense of hearing as being concerned with sounds. But silence, whatever it is, is not a sound — it’s the absence of sound,” said lead author Rui Zhe Goh, a Johns Hopkins University graduate student in philosophy and psychology. “Surprisingly, ...

Researchers at The University of Queensland have discovered the venom of a notorious caterpillar has a surprising ancestry and could be key to the delivery of lifesaving drugs. A team led by Dr Andrew Walker and Professor Glenn King from UQ’s Institute for Molecular Bioscience found toxins in the venom of asp caterpillars punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. “We were surprised to find asp caterpillar venom was completely ...

Research led by the Milner Centre for Evolution at the University of Bath looking at the evolution of terrestrial orchid species has found that global cooling of the climate appears to be the major driving factor in their diversity. The results help scientists understand the role of global climate on diversity of species, and how our current changing global climate might affect biodiversity in the future. One of the largest families of plants, there are around 28,000 species of orchids growing across the world. These plants are known for their huge variety of different sized and shaped flowers, so why are there so many species Climate change driving speciation Charles ...

Human memory is fundamental to everything we do. From remembering the faces of someone you just met to finding your cell phone that you just left on a table, one's "visual working memory"— the core cognitive system that retains visual information in an active state for a short period of time, plays a vital role. Prior work has found that visual working memory capacity is well correlated with other important cognitive abilities such as academic performance, and fluid intelligence, which includes general reasoning and problem solving, so understanding its limits is integral to understanding how human cognition works. In the past, theories have proposed that an individual’s ...
