This as a fundamental study that comprehensively examines the roles of nine structural proteins in herpes simplex virus 1 (HSV-1) viral assembly. They say the thoroughly executed research yields compelling data that explain previously unknown functions of HSV-1 structural proteins.
HSV-1 is a large virus that infects the mucous membranes of the mouth and genitals, causing life-long latent infections. The virus is composed of three layers – a capsid that contains the viral DNA, a protein layer called the tegument and an outer envelope that is studded with viral glycoproteins (proteins with a sugar attached). During replication, newly copied viral genomes are packaged up into this three-layer structure in a process called viral assembly. While some drugs can block the virus’ DNA replication and alleviate symptoms, there is no permanent cure. A deeper understanding of the assembly process could inform the design of novel treatments or cures that inhibit virus formation.. But until now, pinpointing the role of different HSV-1 components in the viral assembly process has proved challenging.
Viral assembly involves a multi-step process, starting in the cell’s nucleus with assembly of capsids, packaging of the DNA to form ‘nucleocapsids’, and transport of these nucleocapsids out of the nucleus via a process of primary envelopment and de-envelopment to travel across the nuclear envelope. This is followed by a secondary envelopment in the cellular area surrounding the nucleus, called the cytoplasm (cytoplasmic envelopment). Imaging methods that maintain the HSV-1-infected cells as close to physiological conditions as possible are needed to fully understand this complex, three-dimensional (3D) assembly process.
The authors used an emerging 3D imaging approach to study the envelopment mechanism and investigate the importance of different HSV-1 genes for viral assembly by investigating the impact of specific mutation of these viral genes. Their new approach combined two methods – cryo-structured illumination microscopy (cryoSIM) to detect fluorescently labelled capsid or envelope components, and cryo-soft-X-ray tomography (cryoSXT) to identify the cellular substructure in the same infected cells. Together, this ‘correlative light X-ray tomography’ (CLXT) approach makes it possible to identify specific structural components within the viral assembly process, allowing the team to visualise exactly where the assembly process stalls for each mutant virus, and providing insights into the unmutated gene’s usual role in viral assembly.
The authors captured different assembly stages during cytoplasmic envelopment using their mutant viruses and showed that – contrary to previous theories – cytoplasmic envelopment is caused by the budding of a capsid into an intracellular membrane ‘sack’ or vesicle, and not by the capsid being ‘wrapped’ by the vesicle membrane. A further new finding is that this budding is asymmetric; the team observed several instances of stalled viral assembly where groups of capsids were gathered at one region, or side, of a spherical vesicle.

Metrology is the science of measurement and forms an excellent basis for scientific and technological advancements. That is where the application of measurement standards for diversified fields originates, with requirements of accuracy, precision, and reliability. The topic involves three main streams: scientific metrology, which is concerned with the development and maintenance of measurement standards universally; industrial metrology, which deals with the accuracy of measuring manufactured goods and their related processes; and legal metrology, which involves regulated measurements within a country for consumer protection and to promote fair trade practices. These three combined allow the various industries and countries to represent consistent, readable measurements.
Scientific Methods in Metrology
Scientific methods coupled with metrology provide the backbone and standardized tracks upon which measurement accuracies are attained and verified. One of the central aspects of metrology is defining measurement standards, such as the International System of Units. These have been upgraded to newer and more state-of-the-art research, such as the redefinition of the kilogram based on the Planck constant in 2019.
Other critical processes include calibration, which tests the precision of measuring instruments against known standards by traceability, linking all the measurements with international references. Uncertainty analysis also plays a vital role in metrology. It presents any measure's possible mistakes and limitations, turning it into a transparent and reliable one. Inter-laboratory comparisons give further validity to the measurement methods and help reach coherence among different institutions.
The Role of Metrology in Science
High-end instruments and techniques grafted onto metrology form its identity. Atomic clocks, interferometers, and spectrometers have been devised based on state-of-the-art scientific ideas promising unprecedented accuracy. Theoretical models have also been proposed to foresee the effects arising in measurement. Quantum mechanics provided a proper basis for these latest steps forward in timekeeping and electrical resistance standards. These techniques and technologies describe in detail the processes that constitute the work of metrology in science and technology. Thus, metrology is central in science.
Proper and consistent measurement is the backbone of experimental research by which scientists can study and understand many diverse aspects of nature. High-precision metrology has discovered many things in quantum physics, cosmetology, and material sciences, hence innovation in nanotechnology and biotechnology. It finds essential applications in semiconductor manufacturing, where finished products have micro-measurements.
Beyond driving innovation, however, metrology assures the quality and safety of everything medical that rely on the dependability of MRI scanners and blood pressure monitors to monitor environmental pollutants, measure climate variables, and follow the use of natural resources.
It has also led to the introduction of international cooperation. Metrology provides the basis for measurement, upon which all communication and collaboration among researchers and industry, or even governments, rests worldwide. Whether it involves vaccine development or space missions, consistency and accuracy of measurement are indispensable for the successful execution of global efforts.
Metrology supportively contributes to economic integrity through its assurance of fair trade and commerce dealing right from the much-used weighing and measuring in market transactions. The legal and regulatory systems that draw from this measurement create trust and build confidence in trade and consumer practices.
Indeed, metrology has proven to be a very important contributor to the sustainability journey toward the fight against global challenges.

Understanding the Significance of Additives in Blood Collection Tubes
Image: Kaustubh Ravan
Blood tests are a cornerstone of medical diagnostics. Whether you're checking for infections, monitoring chronic conditions, or assessing overall health, blood collection plays a critical role. However, what happens after a blood sample is taken is just as important as the collection itself. Blood collection tubes with specific additives are essential for maintaining the integrity of the sample and ensuring accurate test results. Here's why they matter.
Overview of Blood Collection Tubes
Blood collection tubes have revolutionized lab testing by simplifying how samples are prepared for analysis. These tubes are designed to preserve the sample, enabling laboratories to process and investigate blood components effectively. They come in various types, each tailored to specific testing requirements.
Types of Blood Collection Tubes
Different types of tubes are used depending on the test being performed. Here are some of the most common ones:
• Serum Tubes: Used for chemistry tests, these tubes often contain a clot activator to speed up the coagulation process. After centrifugation, serum is separated for analysis.
• Plasma Tubes: These contain anticoagulants like heparin or EDTA, preventing blood from clotting. Plasma, the liquid portion of blood, can be extracted for various tests.
• Anticoagulant Tubes: These are used in tests like CBC (Complete Blood Count) and coagulation studies. Common additives include EDTA, sodium citrate, and potassium oxalate.
Each tube serves a specific purpose, making it essential to choose the right one for accurate diagnostics.
Color-Coding and Its Significance
Ever noticed those bright-colored tops on blood collection tubes? That color isn't just for looks—it serves as a critical guide. Each color indicates the specific additive inside the tube. For example:
• Red: No additive or a clot activator for serum collection.
• Purple/Lavender: EDTA for hematology tests like CBC.
• Light Blue: Sodium citrate for coagulation studies.
• Green: Heparin used for plasma tests in chemistry.
This universal color-coding system eliminates confusion and ensures that healthcare professionals handle each sample correctly, minimizing errors.
What Are Additives in Blood Collection Tubes?
Additives are substances included in blood collection tubes that either preserve the sample or prepare it for testing. Without these additives, blood samples could degrade quickly or fail to meet the lab's specific needs.
Common Additives and Their Functions
Here’s a closer look at some of the most widely used additives and how they work:
1. EDTA (Ethylenediaminetetraacetic Acid)
o Function: Prevents clotting by binding calcium in the blood.
o Common Use: Hematology tests (e.g., Complete Blood Count).
2. Heparin
o Function: Inhibits thrombin to prevent clot formation.
o Common Use: Plasma separation for chemistry tests.
3. Sodium Citrate
o Function: Prevents coagulation by binding calcium.
o Common Use: Coagulation studies (e.g., PT/INR).
4. Clot Activators
o Function: Speeds up clotting for serum collection.
o Common Use: Chemistry panels, hormone testing.
5. Gel Separators
o Function: Keeps different components of blood separate after centrifugation.
o Common Use: Serum or plasma-based tests.
These additives are purpose-built to address specific laboratory needs, ensuring results you can trust.
How Additives Affect Test Results
The additive inside the tube can directly impact test outcomes. For instance, using the wrong anticoagulant may alter the blood's chemical composition, leading to unreliable results. That’s why it's crucial to use the correct tube type and additive. Even small errors, like underfilling a tube, can throw off the delicate balance of additives and blood, compromising the results.
Best Practices for Handling Blood Collection Tubes with Additives
Proper handling of blood collection tubes is essential to safeguard sample quality and, ultimately, patient care. From collection to analysis, every step matters.
Mixing and Storage Guidelines
Once a sample is collected, tubes should be gently inverted several times to ensure the additive is evenly mixed with the blood. Vigorous shaking should be avoided, as this can damage cells or lead to hemolysis (the breaking down of red blood cells).
Storage is another crucial factor. Most samples should be processed quickly or stored at specific temperatures. Always follow the recommendations for each type of tube to prevent degradation.
Avoiding Contamination
Cross-contamination poses a major risk during blood collection. To prevent it, healthcare professionals must use separate tubes and needles for each patient, keeping workspaces clean and organized. Labeling each tube accurately and immediately after collection reduces errors and ensures proper sample identification.
Blood Collection Tubes Industry
The global blood collection tubes market was valued at approximately USD 2.3 billion in 2023 and is expected to grow at a compound annual growth rate (CAGR) of 5.4% from 2024 to 2032, reaching an estimated USD 3.6 billion by 2032.
Several factors are driving this growth:
• Rising demand for diagnostic tests due to aging populations and chronic diseases like diabetes and cardiovascular conditions.
• Advancements in healthcare infrastructure in developing countries.
• Innovations in blood collection tubes, such as improved materials and safety designs, reducing the risk of contamination or injury.
As healthcare continues to advance, the demand for high-quality blood collection tools will only get stronger.

5 Ways for Pharmaceutical Cleanrooms to Achieve New GMP Standards
As the pharmaceutical industry faces tightening regulations and potential supply chain disruptions, both domestically and internationally, manufacturers must prioritize maintaining Good Manufacturing Practices (GMP) to ensure continued success and differentiation in a highly competitive market.
Achieving GMP-compliant cleanrooms is vital for ensuring the highest standards of product safety, quality, and efficacy. However, compliance is just the starting point—these cleanrooms must also be designed to optimize performance, minimize contamination risks, and enhance operational efficiency. With ongoing regulatory updates, particularly around Annex 1, pharmaceutical companies need to stay ahead of the curve by implementing strategies that prevent disruptions to production while meeting the ever-evolving compliance requirements. Here are five key cleanroom considerations to ensure regulatory changes do not disrupt operations.
1. Cleanroom Materials and Construction
Achieving GMP compliance begins long before cleanroom construction starts. It begins with selecting a cleanroom manufacturer partner who provides certificates of compliance and ensures that materials used in construction are free from contaminants. Proper handling of materials is crucial to avoid cross-contamination during manufacturing. Non-porous surfaces and chemical-resistant materials should be chosen to ensure the durability and ease of sterilization needed in pharmaceutical production environments.
"The choice of materials and how components are sealed is essential," says Mark Zabala, expert in cleanroom design, regulatory compliance and senior sales manager of modular cleanroom, SERVICOR™, by Nortek Air Solutions CleanSpace. "Any gaps or seams left during construction can introduce potential contamination and structural risks." Cleanrooms designed with steel modular components, like SERVICOR, ensure that the structure is sound and allows for a custom fit to meet the unique needs of each facility. These features are particularly critical for pharmaceutical manufacturing where contamination control is paramount.
2. Flush Walls and Flush Ceilings: A Foundation for GMP Pharmaceutical Cleanrooms
A key feature in GMP-compliant pharmaceutical cleanrooms is the removal of surfaces that could harbor contaminants or complicate cleaning processes. Flush walls and ceilings are essential to maintaining a contamination-free environment, as they are much easier to clean and maintain.
"Flush surfaces minimize the potential for microbial growth or particle generation, which is vital for processes like aseptic filling or sterile drug production," Zabala explains. "Eliminating joints, seams, and fixtures that are difficult to clean significantly reduces the areas where contaminants can accumulate."
This design not only makes cleaning more efficient but also ensures the integrity of the cleanroom environment is upheld, especially for critical pharmaceutical applications where sterility and minimal contamination are non-negotiable.
3. Airflow and HVAC Systems: Controlling Contamination at the Source
Airflow and HVAC systems are fundamental to maintaining GMP cleanroom standards. These systems regulate air change rates and filter airborne particles, ensuring minimal contamination. Pharmaceutical cleanrooms typically use high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filters to capture airborne particles and microorganisms that could compromise product quality. "The HVAC system must maintain specific airflow rates and pressures while ensuring uniform air distribution," says Zabala. "This is crucial to preventing cross-contamination and ensuring that the air in critical areas remains uncontaminated."
Well-designed airflow systems prevent contaminants from circulating within the cleanroom by pushing them toward escape or return vents. Proper placement of equipment, workstations, and technology is key to not obstructing this critical airflow, which is designed to maintain the cleanroom’s stringent requirements. Additionally, pressure differentials—positive pressure in sterile zones and negative pressure in hazardous areas—are essential to controlling the flow of air and ensuring containment where needed.
4. Advanced Monitoring and Data Logging Challenge
As technological advancements continue to evolve, monitoring systems in pharmaceutical cleanrooms must become more sophisticated to ensure consistent compliance with GMP guidelines. These systems track critical environmental parameters, including temperature, humidity, particle counts, pressure differentials, and access control. "Real-time monitoring is vital for maintaining GMP standards," says Zabala. "Automated monitoring systems provide continuous data logging, allowing operators to track trends and take proactive steps if any environmental parameters go out of specification."
These systems trigger alarms if particle counts or other conditions exceed predefined thresholds, enabling rapid corrective actions. Beyond regulatory compliance, data logging is critical for traceability during inspections and ensures transparency and accountability.
A recent study found that information management already takes up nearly 30% of staff time. Digital twin technology, applied to Automated Material Handling Systems (AMHS), allows for a virtual replica of the cleanroom logistics to be created. With an expected increase in the number of organizations using these twins for data logging, pharmaceutical manufacturers can streamline and continue to innovate to increase speed to market.
5. Validation and Continuous Improvement
Validation is the final step in ensuring that a pharmaceutical cleanroom is fully GMP-compliant. This process involves rigorous testing and measurements to confirm that the cleanroom’s environmental conditions are within acceptable parameters and that all systems are functioning correctly.
"Validation ensures the cleanroom supports the production of high-quality, safe pharmaceutical products," Zabala explains. "It’s not just a checkbox to get up and running, it’s about verifying that the environment is continuously controlled and monitored."
Once operational, ongoing monitoring, regular maintenance, and requalification are essential to maintaining compliance. This continuous improvement process ensures that the cleanroom adapts to evolving industry standards and remains efficient, reducing the risk of non-compliance or production delays.
A Holistic Approach to GMP Pharmaceutical Cleanroom Compliance
To meet GMP standards, pharmaceutical cleanrooms require a holistic approach that includes cutting-edge design features, continuous monitoring, rigorous material selection, and thorough validation processes. Critical elements such as flush walls and ceilings, advanced airflow systems, and real-time data logging all contribute to a sterile environment capable of meeting the exacting requirements of pharmaceutical production.
Additionally, comprehensive Standard Operating Procedures (SOPs) are essential. The perfect cleanroom design will only be effective if backed by SOPs that govern gowning, cleaning, maintenance, and behavior within the cleanroom. Working with professionals to create robust SOPs will ensure the cleanroom operates as intended, further supporting GMP compliance.
As regulatory requirements continue to evolve globally, pharmaceutical cleanroom design must be treated as an ongoing process that demands attention to detail, regular reassessment, and operational excellence. By integrating the latest technologies, materials, and monitoring systems, pharmaceutical manufacturers can ensure their cleanrooms not only meet current GMP standards but also provide a foundation for future innovation and growth.

ASM Calls for Reinstatement of CDC Public Health Resources
On behalf of the American Society for Microbiology (ASM), which
represents over 37,000 scientists and health professionals dedicated to
advancing the microbial sciences, I write to express our deep concern
regarding the recent removal of critical public health resources from
the Centers for Disease Control and Prevention (CDC) website. These
actions threaten access to essential scientific data and public health
information, which are vital for research, disease prevention and
evidence-based policymaking.
Recent reports
indicate that more than 3,000 pages of CDC public health content have
been taken down, including diagnostic and treatment guidelines and
information on certain vaccines. These resources serve as a cornerstone
for health care providers, researchers and public health officials in
their efforts to prevent and control infectious diseases, reduce chronic
disease burdens and respond to public health emergencies.
The removal of this content significantly hinders scientific progress
and weakens the ability of medical professionals to provide timely,
evidence-based care. For instance:
- Research Loss: The deletion of more than a thousand research articles limits the ability of scientists to build on existing findings, develop new interventions and address pressing public health challenges.
- Removal of Datasets: Datasets facilitate timely reporting of infectious diseases and epidemiologic research. These are critical for monitoring and responding to national, state and local outbreaks and public health needs.
- Health Care Disruptions and Negative Impact on Patient Care: Without access to up-to-date diagnostic and treatment guidelines and vaccine information, health care providers face unnecessary barriers in managing and mitigating the spread of infectious diseases. As a result, patients will suffer.
Scientific progress and effective public health interventions rely on
accurate and timely information including high-quality, peer-reviewed
research and clinical guidelines. Removing these resources not only
disrupts ongoing research but also undermines the ability of medical
professionals to respond to public health threats. We urge your
leadership in ensuring that these vital resources remain available to
the scientific and health care communities.
Thank you for your attention to this critical issue. ASM stands ready to
assist in efforts to restore access to these essential public health
materials. If you have any questions, contact JR Kane, Government
Relations Manager, at jkane@asmusa.org.
