In an era where biodiversity conservation is increasingly in the spotlight, technological innovation has become a crucial force in protecting endangered species. Recently, the Southeast Asian animal cell “Noah’s Ark,” a project jointly established by Singapore’s Mandai Wildlife Group and scientific research institutions, was officially launched. In this cross-species conservation initiative, specialized cryogenic storage equipment such as the cryo flask plays an essential role, offering core support for the safe handling and transport of cellular samples while setting a new industry benchmark for the application of cryogenic equipment in ecological research. This “treasury of life” is located at the Lee Kong Chian Natural History Museum of the National University of Singapore and the Mandai Wildlife Reserve. Unlike traditional animal conservation methods, it stores not whole animal specimens but cells and tissue samples that carry the core biological information of species. Maintaining the long-term viability of these “sparks of life” requires an ultra-cold storage environment. As the operator of Singapore’s five major wildlife parks, Mandai Wildlife Group has developed specialized cooling technology that allows cells to enter a dormant state under cryogenic conditions. These cells can later be thawed as needed for normal growth and replication, preserving invaluable “biological backups” for...

A recent study published in Nature Biomedical Engineering by a research team from Kyoto University highlights the synthesis of a novel protein named “Crunch,” which can precisely guide phagocytes to remove target waste cells in the body. This breakthrough offers new potential pathways for treating diseases such as cancer and autoimmune disorders. Supporting such cutting-edge biomedical research, essential equipment like the large nitrogen tank—a type of cryogenic storage device—plays a critical role in preserving sample viability and facilitating the translation of scientific results. The study indicates that the human body generates numerous waste cells daily. Under normal conditions, these cells release “clearance signals” during apoptosis, enabling phagocytes to identify and remove them. However, due to aging or environmental factors, some waste cells lose their ability to undergo normal apoptosis. Their accumulation can impair organ function and even lead to malignant tumors. Previous methods for clearing such stubborn cells were limited and risked damaging healthy cells. The advent of Crunch protein has overcome this challenge. This novel protein offers two core advantages: precision and flexibility. On one hand, it specifically binds to target waste cells, guiding phagocytes to remove them accurately and minimizing harm to normal cells. On the other hand,...

Early morning at the Hanji Cattle and Sheep Trading Market in Linxia County is bustling with energy and a sense of industrial progress. While traders like Chen Meo’er still use traditional “sleeve negotiation” gestures to close deals for Qinchuan cattle, the market itself—boasting a 7,000-square-meter trading hall and 24-hour accommodation—has long left behind the days of “weather-dependent trading.” Today, the transformation of Linxia’s livestock industry is not only visible in improved trading conditions but also powered by technological devices such as high-performance cryo shipping containers that enable upgrades across the entire chain—from genetic improvement to product distribution. Market modernization has steadily raised breeder confidence. Young farmer Yang Lelei, who started with just a few heads eight years ago, now runs a herd of 200 cattle. “In the past, we relied solely on manual labor—feeding and cleaning were exhausting. Now, with mechanized equipment, one person can do the work of several.” More importantly, e-commerce channels have significantly expanded his beef and mutton sales from local markets to nationwide customers. Upstream, technology plays an even more essential role. Linxia Longshengyuan Agricultural Technology Co., Ltd. collaborates with scientific institutions to establish advanced breeding systems, introduce automated monitoring equipment, and use high-quality liquid nitrogen...

Organ transplantation serves as a “l(fā)ifeline” for many patients with end-stage diseases, with over 50,000 such procedures performed annually in the United States. However, immune rejection remains a critical challenge—when genetic compatibility between donor and recipient is insufficient, the immune system attacks the transplanted organ as a foreign invader. In areas such as donor organ research and immune cell sample processing, deep-freeze liquid nitrogen storage is often used to maintain cell viability, providing a stable low-temperature environment essential for medical research. Recently, Dr. Leonardo Ferreira and his team at the Medical University of South Carolina (MUSC) published a groundbreaking study in Frontiers in Immunology, developing a novel genetically modified immune cell that opens a new path toward precisely addressing transplant rejection. Led by Dr. Ferreira, assistant professor of pharmacology and immunology, the team successfully created a genetically engineered immune cell (CHAR-Tregs) capable of precisely targeting and inhibiting antibody-producing B cells that trigger organ rejection. While similar genetically modified immune cell strategies have previously been used to activate the immune system against certain cancers, this is the first time such cells have been shown to effectively “quiet” immune responses that cause organ rejection, overcoming limitations of traditional immunosuppressive approaches. Clinicians have...

In the field of cancer therapy, “precisely targeting cancer cells while minimizing damage to healthy tissue” is a core focus of global medical research. In recent years, China’s clinical frontlines have seen multiple independent innovations—such as nanomaterial drug delivery, AI-guided adaptive radiotherapy, and minimally invasive ablation for brain tumors—accelerating the shift toward precision medicine. Behind the development and implementation of these technologies, the role of key cryogenic storage equipment has become increasingly vital. Among these, the storage cryogenic flask, with its stable ultra-low temperature environment, has become essential for preserving research samples and supporting clinical translation. Endometrial cancer, one of the three major gynecological malignancies, continues to rise in incidence, and the limitations of traditional chemotherapy—which often harms healthy tissues—remain a challenge. Recently, a collaborative effort led by Peking University People’s Hospital developed a “synthetic high-density lipoprotein nanodisc carrier,” offering a new solution. These nanodiscs, only 10 nanometers in diameter, act like “artificial cellular couriers” that precisely deliver chemotherapy drugs to cancer cells while activating the immune system. During multi-center clinical trials, the storage cryogenic flask played a critical role: its stable -196°C environment preserved the biological activity of nanodiscs, ensuring sample integrity during transport and storage across institutions, thereby...

In recent years, the global market for veterinary assisted reproductive technologies has shown rapid expansion. According to data, this market is expected to grow from $8.5 billion in 2025 to $18.8 billion in 2035, reflecting a compound annual growth rate of 8.2%. Cattle breeding, which accounts for 38% of the market, serves as a primary driver. The liquid nitrogen small container used to store frozen bovine semen is witnessing rising demand alongside the increasing use of artificial insemination. Long-term preservation of high-quality bull semen plays a crucial role in enhancing reproductive efficiency within the cattle breeding sector. Storage at -196°C suppresses metabolic activity in sperm, allowing it to remain viable for years or even decades. Compared to conventional approaches, modern storage tanks are designed with high-vacuum insulation that minimizes daily evaporation rates. This significantly reduces how often refills are needed, making these containers especially suitable for large-scale breeding centers and farms. As technology evolves, storage dewars for frozen bull semen are incorporating more user-oriented improvements. For instance, the use of organized canisters allows samples to be sorted by bull breed or collection date. Combined with a barcode tagging system, this can improve retrieval efficiency by more than 40%. In addition,...

Cell culture technology serves as a foundational pillar in pharmaceutical production, regenerative medicine, food science, and materials engineering, with its quality directly influencing the outcomes of downstream research and industrial applications. As the “nutritional core” for cell growth, cell culture media provide essential components that maintain cell viability, and optimizing formulations for specific scenarios is crucial for enhancing cultivation efficiency. In recent years, machine learning has become a vital tool in media optimization, yet biological variability in experimental data—such as fluctuations in cell behavior and equipment noise—limits model accuracy. Throughout the entire cell culture process, the liquid nitrogen refrigerator, with its stable -196°C environment, serves as critical equipment for long-term sample storage, ensuring the safety of highly viable cells obtained through optimization and bridging the continuity between cultivation and storage. A recent study successfully applied a machine learning model designed to handle biological variability to optimize serum-free media. Using CHO-K1 cells, commonly employed in pharmaceuticals, cultured in media with different formulations, the research quantified biological variability and integrated data on media composition and cell density into a multi-algorithm machine learning framework. Iterative training and validation improved model reliability. The resulting specialized serum-free media increased cell density to 1.6 times that...

Breakthrough in Stem Cell Meiosis Research Supported by Cryogenic Storage Solutions A joint research team from the Wyss Institute at Harvard University and Harvard Medical School recently published a significant study in Science Advances, demonstrating for the first time the successful induction of meiosis in human induced pluripotent stem cells (iPSCs) in vitro. This breakthrough offers new potential pathways to understanding human reproductive development and addressing infertility challenges. Throughout the study, the reliable preservation of biological samples using ultra-low temperature storage equipment—such as that provided by cryogenic liquid nitrogen tank suppliers—proved essential to supporting these research outcomes. Approximately one in six adults worldwide is affected by infertility. Although assisted reproductive technologies continue to advance, defects in early germ cell development—particularly meiotic abnormalities—remain a major cause. Meiosis is a complex and tightly regulated process essential for the formation of reproductive cells. Even minor deviations can result in embryonic aneuploidy, severely impacting fertility outcomes. Previously, conventional methods required converting iPSCs into primordial germ cells (PGCs) before inducing meiosis, an inefficient and often unsustainable approach that limited research progress. The research team pioneered a new strategy that completely bypasses the PGC stage. By genetically modifying stem cells to emit fluorescent signals upon initiating...

Data from the Irish Cattle Breeding Federation (ICBF) reveals that widespread adoption of portable liquid nitrogen containers is transforming dairy breeding practices. As of August 1, 2025, national artificial insemination (AI) services reached 1,279,357—a surge of 72,818 year-on-year. This growth will directly fuel the recovery of heifer calf births in 2026, reversing current declines. I. Breeding Crisis & Technological Breakthrough Early 2025 confronted Ireland’s dairy sector with critical challenges: Dairy calf registrations fell 1.4% YoY by April 1 (16,000 fewer head) Heifer registrations plummeted 11.5% (38,000 fewer), threatening 2027’s replacement stock First-calving cows decreased by 25,000 (9%) Root cause analysis traced this to three consecutive years of declining AI services (2022: -12%, 2023: -7%, 2024: -14%), directly reducing heifer output. The 14% YoY rebound in 2025 AI services pivoted on scaled deployment of portable liquid nitrogen containers. Their cryogenic stability (-196°C) ensured semen viability, enabling rapid response to breeding demands. II.
