NEWS RELEASE: Freudenberg Medical launches CleanAssure, an ISO class 5 controlled cleanroom for sterile single-use assemblies New controlled cleaning and sterilization service supports biopharma customers with ready-to-use single-use assemblies Kaiserslautern, Germany — Freudenberg Medical, a global contract design and manufacturing partner to the medical device and biopharma industry, announced the launch of CleanAssure, a new ISO…
In the past, even with an icebreaker and during peak melt season, getting to the North Pole wasn’t a sure bet. It took favorable winds to crack the frozen ocean surface, and ships had to fight through ice that had grown many meters thick over several winters. In the summer of 2025, though, Jochen Knies from the Arctic University of Norway, Tromsø, and his team met little resistance on their way to 90 degrees North with the research vessel Kronprins Haakon. The geologist “didn’t hear the usual grinding of ice” against the hull that he remembered from 1996, when he first reached the pole by ship. Instead, thin floes and large stretches of open water made for an easy, quiet passage. To him, it was “a reminder of how quickly the Arctic is changing.”
Since the late 1970s, when satellite observations of the polar seas began, summer ice cover of the Arctic Ocean has declined by more than 40%. In less than half a century, a frozen area the size of the Mediterranean Sea has turned into blue open water with the rapid warming of the high northern latitudes. If this trend continues, there could soon be summers at the North Pole with no sea ice whatsoever. The last time this happened may have been some 120,000 years ago. But no one knows for certain.
That’s why Knies and his colleagues, a team of researchers from Norway and Germany, set out from Svalbard to the central Arctic last August. The aim of their five-week mission was to determine whether this region had been ice-free in recent Earth history—and if so, when. As part of a €12.5 million project financed by the European Union, they also came to answer some questions about the future of the Arctic and beyond: How does the loss of sea ice affect the marine ecosystem? What are the consequences for ocean circulation and global climate?
In search of clues, the expedition collected sediment cores up to 22 meters in length at different locations across the Arctic seafloor. Marine sediments are valuable climate archives that give scientists a window into bygone eras. Like diligent record keepers, they can log past water temperatures, sea-ice coverage, and the strength of ocean currents. These data are encrypted in the chemical and physical properties of the plankton remains and weathered rock deposited on the seabed.
The ship’s crew and researchers recover the sediment corer, a 25-meter-long steel pipe that is driven into the seafloor using a top weight of more than three metric tons.

Together, the scientists pull out long plastic pipes filled with precious deep-sea mud.

The pipes are cut into shorter pieces and split in half before being processed in the ship’s laboratories. Each of these one-meter sections covers several tens of thousands of years of Earth’s history.

While sediment cores several meters long had been recovered on earlier expeditions in the central Arctic, there is no scientific consensus on how old the deposits actually are or whether sea ice ever completely disappeared in summer.
To decode the Arctic’s climate archive, Knies brought a team of experts from various disciplines onboard the Kronprins Haakon to dig deeper and obtain fresh samples they could subject to the latest analytical techniques.
Samples await paleomagnetic dating. Like tiny compass needles, iron-rich particles align with Earth’s shifting magnetic field as they settle on the seabed. By measuring their orientation, researchers can estimate the age of the different sediment layers.

Under the microscope, PhD student Paulina Romel picks shells of unicellular foraminifera from a sample. The chemical composition of these microfossils can give clues about the age of the sediment and the surface water temperature when the organisms were still alive. “These are really cool creatures!” says Romel.

Agathe Ollive, a geochemist from the Alfred Wegener Institute in Germany, takes water samples from a CTD rosette, an instrument package that measures conductivity (salinity) and temperature at various depths. She uses certain elements to trace the inflow of fresh water and seawater from rivers and adjacent ocean basins into the Arctic. “I didn’t expect there to be so little ice up here,” Ollive says. She is worried about how the Arctic will look 20 years from now.
TIM KALVELAGE
Some of this work was done while the researchers were still at sea. Now, at their home laboratories, they are finalizing their analysis of the seafloor samples. One important task is dating the sediments, which may be up to 2 million years old. The team uses a combination of methods to do this, including measuring magnetization, the decay of radioactive elements, and the exposure of mineral grains to sunlight before sinking to the depths. Once they can place them on a timeline, the materials in the cores will help researchers paint a picture of what the Arctic Ocean looked like in times that were warmer than today. For example, the presence or absence of the molecule IP25, which is produced exclusively by ice algae, could tell them how far the sea ice receded at a given time.
Toward the end of the expedition, the Kronprins Haakon passes this iceberg near the northeast coast of Greenland.
TIM KALVELAGE
At the end of the study, the team hopes to have data that could improve climate projections for a future ice-free “blue Arctic,” helping us understand how it could affect marine life and carbon storage, Atlantic Ocean circulation, or extreme weather events in Europe and North America.

Freudenberg Medical, a Kaiserslautern, Germany-based contract design manufacturing partner, launched CleanAssure, a new ISO Class 5 controlled cleanroom designed to deliver clean and sterile single-use assemblies for biopharmaceutical customers, according to the company.
Freudenberg Medical manufactures silicone and thermoplastic elastomer (TPE) tubing for bioprocessing and critical fluid transfer. The company specializes in seamless, overmolded single-use assemblies used in vaccine production, cell cultivation, fluid transfer, and fill-finish operations.
The controlled cleanroom enables customers to receive ready-to-use washed, dried, and gamma sterilized single-use assemblies with the highest product quality, sterility, and process consistency, noted Rudi Gall, vp, global pharma, Freudenberg Medical.
“CleanAssure allows us to support our customers beyond component manufacturing,” he said. “By integrating controlled cleaning and sterilization into our single-use assembly services, we help reduce contamination risk, streamline validation activities, and support a reliable supply for our customers. We can now support customers with their entire component value chain and allow them to focus on their core manufacturing capability.”
Freudenberg’s cleaning process uses ultrapure water and air, operating within ISO 5 conditions. The water is produced using a multi-stage filtration process, resulting in high-purity water specifically suitable for pharmaceutical applications.
Key biopharma industry challenges
Biopharmaceutical manufacturers increasingly rely on single-use systems but face ongoing challenges related to cleaning validation, contamination risk, and production downtime. Customer-managed cleaning processes are often time-intensive, costly, and require additional resources while directly impacting supply reliability, according to Gall.
The company explained that its controlled cleaning environment addresses these challenges by reducing cross-contamination risk through tightly controlled ISO Class 5 processing; alleviating customer cleaning validation burden by delivering assemblies washed and sterilized under cGMP, validated conditions; minimizing production downtime by removing cleaning as a process step; and supporting a consistent, reliable supply of high-quality single-use assemblies.
Freudenberg will be attending INTERPHEX New York, April 21–23, Booth 1673, to exhibit its new products and services.

No one’s sure if synthetic mirror life will kill us all
In February 2019, a group of scientists proposed a high-risk, cutting-edge, irresistibly exciting idea that the National Science Foundation should fund: making “mirror” bacteria.
These lab-created microbes would be organized like ordinary bacteria, but their proteins and sugars would be mirror images of those found in nature. Researchers believed they could reveal new insights into building cells, designing drugs, and even the origins of life.
But now, many of them have reversed course. They’ve become convinced that mirror organisms could trigger a catastrophic event threatening every form of life on Earth. Find out why they’re ringing alarm bells.

NASA
The great commercial takeover of low Earth orbit
The International Space Station will be decommissioned as soon as 2030, but the story of America in low Earth orbit (LEO) will continue.
Using lessons from the ISS, NASA has partnered with private companies to develop new commercial space stations for research, manufacturing, and tourism. If they are successful, these businesses will bring about a new era of space exploration: private rockets flying to private destinations.
They will also demonstrate a new model in which NASA builds infrastructure and the private sector takes it from there—freeing the agency to explore deeper and deeper into space. Read the full story.

We can still have nice things
A place for comfort, fun and distraction to brighten up your day. (Got any ideas? Drop me a line.)
Research presented at ESCMID Global 2026 in Munich has shown that antibiotic resistance genes (ARGs) can be present in newborns within the first hours of life, with the newborn gut becoming colonized before, during, or recently after delivery.
Meconium, the first stool passed by newborns, was traditionally thought to be sterile, explained study lead Elias Iosifidis, MD, PhD, from Aristotle University of Thessaloniki in Greece. However, recent molecular studies have detected microbial genetic material in meconium samples, indicating that the neonatal gut may be exposed to bacteria during pregnancy.
It has been suggested that this early microbial exposure could contribute to the development of antibiotic resistance. Indeed, ARGs have been detected in meconium samples, and their presence at this early stage may facilitate the spread of resistance through horizonal gene transfer between bacteria.
To investigate further, Iosifidis and colleagues screened 105 meconium samples that were collected from newborns admitted to a neonatal intensive care unit within 24 hours of birth for 56 different resistance genes associated with commonly used antibiotics.
“This is the largest study of its kind exploring the effect of hospital environment on the collection of ARGs in the neonatal gut,” said lead author Argyro Ftergioti. “We analyzed meconium samples within the first 72 hours of life to capture the earliest snapshot of microbial and genetic exposure in newborns. At this stage, the collection of resistance genes is mainly shaped by maternal transmission, delivery mode, and very early hospital exposures.”
The most frequently detected ARGs were oqxA, a gene that causes resistance to fluoroquinolones (like ciprofloxacin), olaquindox, chloramphenicol, and tigecycline, and qnrS, which contributes to decreased susceptibility to quinolones. These were found in 98% and 96% of samples, respectively.
The study also identified several genes encoding beta-lactamases, enzymes that cause resistance to beta-lactam antibiotics such as penicillins and cephalosporins. Among these, the most prevalent were blaCTXM (55%), blaCMY (51%), and blaSHV (39%). Genes linked to carbapenem resistance (KPC/NDM/GES/VIM), a last-line class of antibiotics, were detected in 21% of samples.
Each sample contained a median of eight resistance genes.
“This finding suggests that a pattern of ARGs is already established at this stage. The neonatal gut harbors a diverse resistome, and the presence of clinically important ARGs so early in life is concerning,” said Ftergioti. “Although some ARGs were expected, their high prevalence across the majority of samples was striking—particularly for clinically critical genes offering carbapenem resistance.”
The team also found associations between resistance genes and several maternal and neonatal factors. The presence of the msrA (macrolide-streptogramin resistance) gene was linked with maternal hospitalization during pregnancy, while a higher number of resistance genes was associated with central venous catheter placement within the first 24 hours of life. Both findings likely reflect exposure to healthcare-associated microbes in hospital settings.
“Surprisingly, resuscitation shortly after birth was associated with fewer resistance genes,” noted Ftergioti. He cautioned, however, that “this finding should be interpreted carefully, as it may reflect differences in early microbial exposure or other clinical factors.”
Overall, the data suggest that both maternal transmissions and early exposure to the hospital environment may contribute to the establishment of ARGs in the neonatal gut.
“While further research is needed to understand how early carriage of resistance genes affects microbiome development and infection risk, these findings highlight the importance of surveillance, infection prevention and control in neonatal care,” Ftergioti concluded.
The genomics community’s long wait for 10x Genomics’ highly anticipated news is finally over. On Saturday night, at the Hard Rock Café Hotel in San Diego—across the street from the American Association for Cancer Research (AACR) conference—the company hosted the “Impossible” party to announce its new spatial instrument—the Atera.
Serge Saxonov, PhD, CEO of 10x Genomics, walking onto the stage to thunderous applause, noted that there is “a gap between what we need to see and what we have been able to measure.” The Atera, which enables whole-transcriptome spatial biology at scale, “obliterates the typical trade offs” that come with existing spatial tools, he said.
“This is the biggest launch in our history. I am the most excited I’ve ever been about any product, or any product category, across the board,” Saxonov told GEN. “It has been a long time in development, and it is what we have known the world needs for a long time. I think it will fundamentally change how we measure and understand biology, and it really puts research on a new trajectory. It is really exciting to be at a place now where we can deliver it to the world.”
Nuts and bolts
Atera offers more plex, throughput, and sensitivity than 10x Genomics’ Xenium—enabling whole-transcriptome at scale. More specifically, when compared to Xenium, Atera has four times the throughput, six times higher plex capacity for targeted assays, 3.6x higher plex, and 2–3x sensitivity for whole transcriptome assays.
10x Genomics Atera
The price for Atera is $495,000, and the instrument measures roughly 53” x 36” x 64” or (4.42 ft × 3 ft × 5.33 ft). Orders are currently being taken, and the instrument will be available in the second half of this year.
The instrument can run up to 800 1 cm2 whole transcriptome samples (FFPE and fresh frozen) per year, with flexible run configurations, and a greater than 5 cm² imageable area per slide (for greater than 2,000 mm² total tissue per run when using all four slides.)
There are 18,000-genes on the Atera WTA (whole transcriptome) with stackable customization of 1,000-gene Atera Select panels available now, and optional stacking of up to three 1,000-gene panels coming in the future.
“Spatial genomics with whole-transcriptome profiling capabilities is the ultimate approach to measure single cells in their tissue context,” Holger Heyn, PhD, ICREA professor at the Centro Nacional de Análisis Genómico (CNAG) and member of the Human Cell Atlas, added. “All other lower-plexity approaches have been just a warm-up phase leading to this application.”
Jasmine Plummer, PhD, associate member of the St. Jude Faculty and director of the Center for Spatial OMICs points out that the whole transcriptome, while exciting, can bring a big “sticker shock” for many researchers because it will require a lot more probes in contrast to a sequencing-based platform, where a library accesses all of the genes.
The instrument uses standard glass microscopy slides, which is exciting to Plummer. In the past, she said, slides have posed a challenge when coordinating with other researchers, and using regular slides will be more “pathology friendly.”
An end to tradeoffs?
Existing spatial technologies, which are still relatively nascent in genomics, have been constrained by tradeoffs between plex, resolution, and throughput. Researchers have had to make choices and prioritize.
“In general, with the landscape as it is today, there is a tradeoff,” Nick Banovich, PhD, VP of scientific development at TGen, and professor of bioinnovation and genome sciences division and director of the Center for Spatial Multi-Omics (COSMO), told GEN. “The closer you walk toward whole transcriptome, the lower the per gene sensitivity.”
“The most exciting thing [about Atara],” he continued, “is that there is still quite good sensitivity with whole transcriptome breadth. That’s the huge advantage of this system; there is no tradeoff anymore.”
However, this launch comes just over three years after Xenium’s launch. Purchasing a new instrument so soon may pose a challenge. Plummer notes: “In this economy, with the uncertainty of scientific funding, it is concerning to ask customers—many of whom just landed a machine—to spend another several hundred thousand dollars.”
Why AACR?
Oncology is one of the most exciting, most promising applications of spatial, especially in the near term, noted Saxonov. This is, in large part, because the work exists across the spectrum—from basic discovery to translation to clinical applications. Spatial is unambiguously important, he asserted.
Unveiling at AACR “just made a lot of sense.”
In addition to the party, the company will host a digital launch event on Tuesday, April 21. Within the AACR program, a presentation from the German Cancer Research Center (DKFZ) will include data generated on the platform, highlighting Atera’s ability to uncover cancer biology not accessible with legacy approaches. Researchers distinguished multiple malignant and stem cell states across disease stages, within a single colorectal tumor sample, and mapped how these populations interact with the surrounding immune microenvironment. The data reveal a more complex immune landscape that could inform future therapeutic strategies and drug development. In addition, two posters (#7116, #6216) will include data from Atera.
The future
10x Genomics said that Atera will play a role in advancing large data studies. For example, the company noted that Atera will enable the goal of the Human Cell Atlas (HCA) as it continues its mission to map every cell type in the human body.
“With the Human Cell Atlas entering its next phase of generating spatially resolved atlases, whole-transcriptome approaches will be the workhorse for data generation,” Heyn told GEN.
“I am excited to see the Atara platform being launched now,” he added. “It is very timely as we ramp up production for the Human Cell Atlas 2.0 phase.”
Atera’s future
The company presented a roadmap with future plans at the AACR event, highlighting spatial proteomics, automation, base by base sequencing (a de novo sequencing assay) and software improvements.
Atera, Saxonov told GEN, is a fundamental platform that the company will continue enabling. It lays the groundwork for the next decade of research and work. This point in time, he said, feels similar to the early days of next generation sequencing (NGS). And although the company will continue to develop its other platforms and product lines, Atera has “massive amounts of headroom to keep building on top of it. It is the convergence of all these different technology stacks and different fields onto one.”
“What the platform can do right out of the gate is exciting. And all the things that it can do in the future will be really, really exciting,” he asserted.
Results from a large U.K. study show that vaccination against respiratory syncytial virus (RSV) at least two weeks before giving birth has a significant protective effect against hospitalization for this infection in babies born to these mothers.
As reported at the congress of the European Society of Clinical Microbiology and Infectious Diseases in Munich this week, the researchers found that vaccination reduced a baby’s risk of being admitted to hospital with serious RSV lung infections in the first months of life by around 80% versus no vaccination.
Notably, the benefit from vaccination increased if mothers were vaccinated at least four weeks before the baby was born, although even if they received the vaccine 10-13 days before delivery the risk of hospitalization for their babies in subsequent months still went down by 50%.
“As the largest study to date examining the impact of this vaccine on infant hospitalization, these findings provide robust evidence that vaccination offers substantial protection against severe illness in young infants,” commented lead author and UK Health Security Agency epidemiologist Matt Wilson in a press statement.
“We found a clear relationship between timing and protection, with effectiveness increasing as the interval between vaccination and birth lengthens, reaching close to 85% when vaccination occurs at least four weeks before delivery.”
After a national RSV vaccination campaign for pregnant women began in the U.K. in September 2024, around 55% coverage was reached by December of the same year. In total, 289,399 infants born between September 2024 and March 2025 were included in the cohort of which around 55% were vaccinated via maternal exposure. Vaccination was considered ‘full’ if mothers received it at least 14 days before giving birth.
The team followed up the babies for around three months after birth to monitor for RSV-associated lower respiratory tract infections requiring hospitalization, which affected a total of 4,594 babies.
Overall, unvaccinated babies had around seven times the rate of RSV‑related hospital admissions compared with babies whose mothers were vaccinated during pregnancy. Preterm infants also benefitted significantly from the vaccine.
“These findings are particularly important for preterm infants, who are among the most vulnerable to severe RSV infection,” said Wilson. “With sufficient time between vaccination and birth, we saw good levels of protection in these babies. Giving the vaccination early in the third trimester, as recommended by the World Health Organization, could protect most preterm infants.”
SPT Labtech and the European Molecular Biology Laboratory’s Genomics Core Facility (EMBL GeneCore) in Heidelberg, Germany, agreed to collaborate to advance fully walkaway automated genomics workflows. As part of the collaboration, SPT Labtech’s firefly®+ all-in-one liquid handling platform has been installed at EMBL GeneCore.
Officials at EMBL GeneCore say they will expand the facility’s capacity to develop new protocols and further validate and optimize existing workflows for challenging applications such as low-input and metagenomics samples to support the broader genomics community. The SPT platform is designed to simplify complex genomics workflows, combining pipetting, dispensing, incubating, and shaking technologies into a single instrument.
The automated protocols use New England Biolabs (NEB) library preparation kits, NEBNext®, to generate libraries from a wide input range. According to a SPT spokesperson, the installation of the company’s firefly+ platform at EMBL GeneCore, combined with NEB kits, creates strong foundation for fully walkaway automation, enabling more streamlined, end-to-end workflows and supporting labs to scale automation more easily.
“The installation of SPT Labtech’s firefly+ platform as part of our collaboration underscores our commitment to remain at the forefront of scientific innovation. Fully walkaway automation will address key bottlenecks in genomics workflows, helping us develop high-quality, scalable NGS protocols,” says Vladimir Benes, head of EMBL GeneCore.
“Our latest collaboration with EMBL GeneCore marks a significant step towards advancing fully walkaway automation, providing end-to-end genomics workflows for a much wider range of applications, including environmental and rare species research,” adds Morten Frost, CCO, SPT Labtech.
“Integration of our library prep kits with SPT Labtech’s firefly+ platform at EMBL GeneCore creates a compelling opportunity for faster, scalable DNA and RNA-Seq workflows,” notes Bjoern Textor, PhD, sales and senior applications manager, New England Biolabs.
A single infusion of zorpocabt agene-autoleucel (Zorpo-cel), an autologous CAR T-cell therapy, has led to a rapid and sustained remission in a patient with multiple life-threatening autoimmune disorders, according to a newly reported case published in Med.
Researchers from the University Hospital of Erlangen at Friedrich-Alexander-Universitat Erlangen-Nürnberg in Germany describe how a CD19-targeting CAR T-cell therapy successfully treated a 47-year-old woman suffering from severe autoimmune hemolytic anemia (AIHA), along with immune thrombocytopenia (ITP) and antiphospholipid antibody syndrome (APLAS). All three conditions are driven by malfunctioning B cells that produce harmful autoantibodies attacking the body’s own tissues.
The patient’s condition had proven exceptionally difficult to manage. Over nearly a decade, she had undergone nine different treatment regimens, including steroids, immunosuppressants, and antibody-based therapies, without lasting success. Her AIHA was particularly severe, leaving her dependent on daily blood transfusions and at risk of organ damage due to chronic anemia and iron overload.
With no effective options remaining, the clinicians, under compassionate use, turned to the CAR T-cell therapy developed by Miltenyi Biomedicine. This technique involves collecting a patient’s own T cells, genetically modifying them to target the B cell marker CD19 and reinfusing them to eliminate the dysfunctional immune cells.
The results were striking. Within just seven days of treatment, the patient no longer required blood transfusions. By day 25, her hemoglobin levels had returned to normal, indicating a complete resolution of the hemolytic anemia. Laboratory markers of red blood cell destruction also normalized rapidly.
Equally notable was the therapy’s broader impact. The patient’s elevated antiphospholipid antibodies—responsible for dangerous blood clots in APLAS—fell to normal levels and remained undetectable through 11 months of follow-up. Meanwhile, her platelet counts stabilized, indicating improvement in ITP without the need for additional treatment.
Researchers attribute this success to a “reset” of the patient’s B cell population. Unlike conventional therapies such as rituximab, which partially deplete B cells, CAR T cells appear to achieve deeper and more durable elimination. When B cells eventually returned months later, they were predominantly naïve, suggesting a reprogrammed and healthier immune profile.
Importantly, the treatment was well tolerated. The patient experienced none of the serious side effects commonly associated with CAR T therapy in cancer patients, such as cytokine release syndrome or neurotoxicity. Some mild liver enzyme elevations and blood count abnormalities were observed, likely related to prior treatments and iron overload rather than the therapy itself.
This is the second clinical win for Zorpo-cel in the treatment of autoimmune diseases this year. In January, the Phase I/II basket trial known as the CASTLE trial reported encouraging early results of Zorpo-cel administration in 24 patients with treatment-resistant autoimmune diseases, including systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and idiopathic inflammatory myopathies (IIM). The therapy showed a favorable safety profile, with no cases of severe cytokine release syndrome or neurotoxicity observed. Efficacy outcomes were strong: 22 of 24 patients met predefined endpoints, including remission in most SLE patients, halted disease progression in all SSc patients, and meaningful clinical responses in the majority of IIM cases.
The case highlights the growing potential of CAR T therapy beyond oncology. Previous studies have shown promising results in systemic autoimmune diseases like lupus, but evidence in hematologic autoimmune disorders such as AIHA has been limited. While the findings are encouraging, researchers caution that this is a single case report. Larger, controlled clinical trials will be necessary to confirm safety, effectiveness, and long-term outcomes across diverse patient populations.
Georg Schett had two things: a young patient deathly ill with lupus, and a couple of mouse studies raising the possibility that special T cells could tame the condition.
The German physician-scientist could produce the cells — chimeric antigen receptors, or CARs — at his institution, which was half the battle. Another hurdle: The patient’s parents. “They were like, ‘Don’t do that. You’re crazy,’” recalled Fabian Müller, Schett’s collaborator at the University of Erlangen-Nuremberg. A widespread fear at the time was that T cells would trigger or worsen autoimmune disease.
The rest of the story is the rare scientific fairy tale: The patient got better. Five years on, she is still in remission, and working in the very clinic where she was treated. Her case upended the world of autoimmune disease, driving a flood of experimentation and investment and offering new hope to millions of patients.
