The recent pandemic brought about by COVID-19 has left a lot of people to rethink the way we conduct our daily lives. From people in authority to the common person you see in the street, no one has not made some acclimation to the new normal in response to the virus. But at the forefront in the battle against the pandemic, the people in the sciences have worked tirelessly in the past months to promote the continuity and normalcy in our day-to-day enterprise. Here are the areas in science that have stepped into the spotlight because of the virus:
The UK is home to some of the most advanced research facilities in the world, many of them housed within the nation’s many world-renowned universities. These facilities aren’t just there for the benefit of students and staff; they are also regularly open to academics and representatives of commercial businesses. Many excellent facilities in the country will be of interest to any science researcher. No matter what your chosen field of academic study is or where your research interests lie, there are lab facilities in the UK that are worth seeing. Below, we have listed just some of the world-class lab facilities that UK universities have to offer.
Laboratory tools and equipment don’t come cheap. And making sure your machines are all in top shape is a must, whether you’re managing a science lab at school or a clinic. Yes, availing of routine maintenance for your facilities is the key to preserve your devices. But giving relevant training to your staff on how to handle the equipment effectively is equally important. Doing this is worth it for a lot of reasons.
In September of this year, a sudden and unexpected explosion at a vast Soviet-era virology campus in Siberia (called Vector) caused widespread panic, as various buildings were set ablaze and windows were torn from their frames. At the heart of the most immediate concerns was the potential spread of dangerous viruses, and while it’s still not clear whether or not the explosion was the result of a deliberate attack, there has been a renewed focus on reinforcing safety structures and minimising the impact of future breaches. Make no mistake; the creation of safe and secure science laboratories is crucial to the environment and the general public as a whole, while this also guarantees the accuracy of findings and drives numerous, high-profile industries.
Most proteins become functional once they acquire their native three-dimensional structure, which is dictated by the primary amino acid sequence of the protein. Denaturation is the process in which proteins, or more specifically, nucleic acids, lose their three-dimensional structure. The occurrence of denaturation can be due to many external factors and subsequently, this event can irreversibly disrupt the protein’s functionality1. Forces Involved in Protein Stability In the cell, linear polypeptides are synthesized from a sequence of mRNA, through a process known as translation. As the polypeptide is synthesized, it begins to fold into its three-dimensional structure in a process known as protein folding. The secondary structure, which includes the alpha helices and beta sheets, is stabilized by intramolecular hydrogen bonds between the amide hydrogen and carbonyl oxygen of the peptide bond that links the amino acids of the primary structure. Interactions between side chains of amino acids that comprise the protein determine the tertiary structure. The structure is firmly maintained due to the strength of hydrophobic interactions and the disulfide that bridges between the cysteine residues of the amino acids.
When you start doing more serious research, you will need to conduct a statistical test. It helps you to determine whether your hypothesis is significant or can be rejected. If you start browsing for statistical analyses online, you will find a large number of possible test that can be chosen depending on your task. In this post, let us focus on a simple example of statistical analysis that would allow us to understand what is statistical significance and what is confidence interval. Building a test scenario To understand the matter lets use some random data which is distributed normally. For this, we can use 100 casual observations of the price tag for the new Nokia 3310 from different sources. The average price is around 50€ with a standard deviation of 10€ Now lets plot how those samples are distributed along with the standard distribution graph:
The term STEM refers to an education that is focused on four specific areas. These areas of study are science, technology, engineering and mathematics. STEM education is supposed to help students uniquely learn these topics, focusing on interdisciplinary studies and applying the knowledge that has been learned. The interest in STEM has changed over time, but here are four reasons to study STEM. Job Opportunities When choosing a career, it is important to consider if there are jobs available in that particular field. In the case of the STEM subjects, this is not a worry. There are a wide variety of jobs available in these four fields. If a person is not interested in working in the STEM fields, specifically, the skills learned in STEM classes can be transferred to most other jobs. This includes skills like innovation and creativity, as well as other skills. Many jobs are STEM-related but are found in other fields.
Artificial Intelligence is part of a computer science program that deals in making machines behave and perform operations that a human being can commit. People have been trying to make devices behave like humans for a very long time, and today, with the help of advanced computing, people can achieve it. Artificial Intelligence, in short, is termed AI. There are various departments where Artificial Intelligence can be extensively used. Out of all departments, the defense is one area where the artificial department has been widely used. Gaming is another department where artificial intelligence is getting used. Gaming is prevalent among youngsters, and when these machines start responding to human beings’ requests, people get more excited. There is both advantage and disadvantage in Artificial Intelligence. One of the significant benefits is that by using artificial intelligence technology, we can make machines perform human activities, thus minimizing human labor. You can use devices to perform work that human beings found difficult. Nowadays, human beings can sit in their office and control their house computer. Not one researcher can invent an artificial intelligence system, and it takes years to build a proper and advanced artificial intelligence system.
Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind, and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time, and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek could emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object. He also quoted that German scientists have found that a meta-material can make the red light around the object.
