First discovered in the 1950s, transmission electron microscopy (TEM) is now one of the most widely used techniques to resolve cellular structures. It bombards a specimen with an electron beam, which is focused with magnetic lenses to give an extremely high-resolution image, making it possible to view subcellular organelles—and sometimes full atoms and molecules—with much more precision than either light or confocal microscopes can provide.
Lab security is critical no matter what kind of lab you work in. Medical labs need to keep patient identities confidential, while pharmaceutical labs and clinical trials face potential risks of theft or tampering. Even academic labs work with sensitive samples that need to be properly secured. Here, we’ll review some of the ways you can safeguard your samples and data from being meddled with by outside parties.
BarTender is the most versatile label printing software available on the market. BarTender 2019, the software’s first full update since 2016, was released this year with changes that yield additional functionality and a more streamlined database creation process. Here, we review the top 4 new additions that will improve how you manage databases and print labels with BarTender.
In 2018, the term “Blockchain” was one of the most searched terms by scientists on Google.1 This technology first appeared ten years earlier as the driving force behind the cryptocurrency, Bitcoin. Since then, many have followed suit, creating more than 2000 different cryptocurrencies worth hundreds of billions of dollars.2 Blockchain is now being implemented in the healthcare industry, with the opportunity to solve many issues currently plaguing healthcare institutions and companies alike.
When you hear 3D printing, what do you think of? Perhaps you imagine creating inanimate objects like chairs, wrenches, or toys out of construction materials (e.g. plastic, ceramic, or metal). The uses of additive printing have evolved way past that and now serve an important role in medicine and research.
The main purpose of any vaccine is to stop the spread of communicable diseases from one person to another and, where possible, to abolish the disease outright from the general population. There are many commercially available vaccines for a variety of viral and bacterial diseases, including diphtheria, tetanus, whooping cough, measles, polio, tuberculosis, hepatitis, human papillomavirus, and influenza. To develop these and other vaccines, three things are required: research to find an antigen (usually a protein produced by the pathogen) that produces a protective immune response against the disease, a platform in which to produce the vaccine, and clinical testing.
Science has recently begun to establish some of the tools that might let us develop a form of synthetic life. Developing cells from scratch ought to let us understand a whole lot more about what actually constitutes a living organism, while making it possible to generate simpler (yet no less sophisticated) life-like organisms that can be more predictably manipulated.1
Cryogenics is one of the most important fields that has been integrated into biomedical research. It’s employed to store a variety samples, including human tissue specimens, blood samples, and primary cells, making cryogenic storage an essential tool for hospitals and research facilities alike. Here, we’ll briefly explore how the field of cryogenics has developed within the last century to produce the storage equipment used throughout the world to perform ground-breaking research and to discover new medical advances.
Climate change is a global phenomenon with wide-ranging and potentially disastrous effects for the entire human population. The consumption of fossil fuels (e.g. coal, oil, and gas) combined with mass deforestation has led to exorbitantly high atmospheric CO2 levels that were only last recorded 800,000 years ago. These high CO2 levels have resulted in a significant increase in the average global temperature, a key factor that has led to the polar ice caps melting at an accelerated pace, making the seas warmer and sea levels higher.1 Heat waves are much stronger than they used to be, record-breaking hurricanes occur much more frequently than before, and we’ve lost nearly 60% of the world’s wildlife.2 It’s been well-documented that these changes are a result of human activities, as worldwide economic and technological progress has led to a consistent increase in the amount of CO2 in the atmosphere. Altogether, this has led to a rise in the average global temperature of nearly one degree Celsius since 1901, with the rate of global warming having doubled since 1975.3
Many industries require barcodes to track their inventory, samples, and equipment. To integrate the data from the barcodes into a tracking system, the barcodes must be scanned when each item is processed. So, how do scanners relay the information from barcodes to a computer?
