Tracking the pathway to immunity, one cell at a time. Vaccines work their magic by effectively producing immune cells that survive for a long time, often for over decades. These immune cells build a barrier of protection that can prevent or minimize re-infection as well as a memory that enables us to identify [...]
You can easily rotate a baseball in your hand by twisting your fingers. But you need inventive scientists with access to world-class scientific facilities to rotate an object that is only two billionths of a meter wide. That is a million times smaller than a raindrop. Scientists at the U.S. Department of Energy’s (DOE) [...]
In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' – a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen [...]
A concept known as "wave-particle duality" famously applies to light. But it also applies to all matter — including you. In 1905, the 26-year-old Albert Einstein proposed something quite outrageous: that light could be both wave or particle. This idea is just as weird as it sounds. How could something be two things that are [...]
In one of the first large, real-world studies comparing the effectiveness of COVID-19 vaccines versus natural immunity in protecting against death, hospitalizations and emergency department (ED) visits for any cause, including COVID, research-scientists from Regenstrief Institute, Indiana University School of Medicine and Vanderbilt University Medical Center report that people of all age groups benefited [...]
Researchers from Spain and Denmark have discovered a technique for attacking cancer cells in the production of one of the origin-of-life molecules. The molecule that gave rise to life, RNA, has been demonstrated to be important for repairing human genetic material and avoiding mutations that might lead to cancer development. Recent research breakthroughs, such as [...]
It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into a blue device, closes the flap and presses a button. After a few seconds there is a [...]
Researchers have discovered that salen can effectively bind a number of proteins of the coronavirus SARS-CoV-2. CoV-2’s Scientists utilized molecular docking to reveal that salen binds to the non-structural protein nsp14, which prevents the virus from being destroyed. The discovery may aid in the development of novel drugs and coronavirus infection treatments. The study’s findings [...]
Autopsies of 44 people who died from COVID-19 in the first year of the pandemic showed researchers that disease-causing SARS-CoV-2 virus spread throughout the body – beyond just a respiratory disease – and remained in tissue for months. The study, from the National Institutes of Health and published in Nature, helped scientists broaden their [...]
New discoveries about cancer-causing genetic mutations may lead to improved ways of predicting and treating the disease. Cancer is the second-leading cause of death in the world, including in the United States. In fact, according to the CDC 1.7 million Americans are diagnosed with cancer and 600,000 people die from it each year. Moreover, [...]
