Neurological conditions leading cause of ill health, disability globally: Lancet

  The analysis suggests that worldwide, the overall amount of disability, illness, and premature death—caused by neurological conditions increased by 18% over the past 31 years NEW DELHI: The number of people living with, or dying from, neurological conditions such as stroke, Alzheimer’s disease, other dementias, and meningitis globally has risen substantially over the past 30 years due to the growth and ageing of the global population as well as increased exposure to environmental, metabolic, and lifestyle risk factors, a new study published in The Lancet Neurology said.In 2021, 3.4 billion people experienced a nervous system condition, according to the analysis from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021.The analysis suggests that worldwide, the overall amount of disability, illness, and premature death—a measurement known as disability-adjusted life years (DALYs)—caused by neurological conditions increased by 18% over the past 31 years, rising from

5 Free Templates for Data Science Projects on Jupyter Notebook

Image
For many professional data scientists, Jupyter Notebook has become their staple working environment. Even for me, it’s always the first place I go to for any data science experiment and workflow. As a data scientist workplace, Jupyter Notebook is a unique IDE as the code can be executed independently in each cell. At the same time, the author could explain each cell. This distinction allows the notebook to be reused by others and become a project template. In this article, we will discuss five free templates for building a data science project on Jupyter Notebook. So, what are these Jupyter Notebook templates? Let’s get into them. The first template that we discuss is not necessarily a complete code project that we can fill in already. The template we would discuss is not only the Jupyter Notebook but also complete projects that support the Jupyter Notebook. What we would have is the Python data science projects by AWS. This template creates a complete data science project structure t

Biophysics: Testing how well biomarkers work

Image
Modern microscopy techniques make it possible to examine the inner workings of cells in astonishing detail. “We can now observe the arrangement and interaction of individual proteins under the microscope,” says Professor Ralf Jungmann, Chair of Molecular Physics of Life at LMU and Max Planck Fellow at the MPI of Biochemistry. The biophysicist’s team recently developed the revolutionary RESI (Resolution Enhancement by Sequential Imaging) method. This technique can be used to improve the resolution of fluorescence microscopy down to the Ångström scale – far below the classical diffraction limit of light. DNA-conjugated marker molecules, which the researchers attach precisely to the molecules they want to understand better, are crucial for this. Jungmann’s team has now presented a technique in the journal Nature Methods that can be used to quantify how well biomarker molecules bind to the target proteins. “This is absolutely crucial if you want to make quantitatively reliable statements,

Could twisted bismuth pave the way to a practical superconductor

Image
A study has found that two atom-thick layers of twisted bismuth might exhibit superconductivity at temperatures significantly higher than the near absolute zero required for a conventional superconductor, like bulk bismuth. “Much has been written about superconductivity on twisted bilayer graphene for certain ‘magic angles’, so it seemed natural for us to investigate the possible existence of superconductivity in other layered materials,” said Ariel Valladares, a professor at the Universidad Nacional Autónoma de México and lead author of the study, in an email. “We were trying to see if this behavior could be considered general or that it only occurs for graphene. Also, new ways to generate superconducting materials have to be explored,” he continued. This would be a remarkable achievement and a significant step, overcoming a major obstacle to practical applications of superconductivity in fields such as computer science, energy, communications, and electronics. Why is creating a supe

Research Insights: Cognitive Dissonance in investor decision-making

Image
It is well established that investors sometimes ignore pertinent information when making decisions about trading stocks. This phenomenon has most often been pinned to bounded rationality, that is, limitations on individuals’ reasoning—for example, due to time constraints or cognitive capabilities. But new research finds that a cause may be cognitive dissonance, the state of holding inconsistent or conflicting thoughts when faced with a behavioral decision. Zhijian Huang, Associate Professor in Saunders College Department of Finance and Accounting, co-authored an article, “Asymmetric response to earnings news across different sentiment states: The role of cognitive dissonance,” published in the Journal of Corporate Finance. Huang and his collaborators tested a hypothesis that earnings announcements contradictory to current market sentiment trigger cognitive dissonance, causing investors to disregard bad news when they are optimistic about the market, and good news when they are pessimi

Thomas Cech’s ‘The Catalyst’ spotlights RNA and its superpowers

Image
The Catalyst is part ode to the oft-overlooked molecule and part detailed history of the scientists who’ve studied it. RNA has clearly ensorcelled Cech. And after reading his book, the molecule may ensorcell you, too. RNA was once considered the “biochemical backup singer” to the diva DNA, Cech writes. But this molecule, a largely single-stranded cousin of DNA, seems to be pretty wondrous all on its own. It can slice, it can splice, it can perform a rollicking array of genetic gymnastics that scientists may still not fully comprehend. Cech, a biochemist at the University of Colorado Boulder, catalogs these abilities in an informative story that offers readers a no-stone-unturned tour of the biochemical basics. Researchers harnessing RNA’s skills have now aimed the molecule at some of medicine’s most pressing problems. Messenger RNA, or mRNA, for example, is the hero of two widely used COVID-19 vaccines and may help scientists rapidly conjure vaccines for other viruses and even cancer (

Lithium-Ion “Traffic Jam” Behind Reduced Battery Performance

This article is part of a series of pieces on advances in sustainable battery technologies that Physics Magazine is publishing to celebrate Earth Week 2024.

Electric vehicles are picking up visibility in the public eye. But their adoption is slowed down by batteries that degrade over time, an issue commercial ventures are especially keen on addressing as they adopt increasingly nickel-rich cathodes—the cathode du jour for high-end electric vehicles. The substitution of nickel for cobalt in earlier versions of these cathodes can improve their performance, but it also accelerates degradation. Earlier this year, Louis Piper, University of Warwick, UK, and his colleagues devised and demonstrated an x-ray technique that can examine industry-grade
