NewsAndelyn Biosciences launches LVV Curator® Platform
Andelyn Biosciences has announced the launch of its LVV Curator® Platform, a standardized lentiviral vector (LVV) manufacturing solution built on the same proven modular approach that supports clinical and commercial adeno-associated virus (AAV) programs.

NewsFDA approves early warning system for sepsis
An early warning system for sepsis, one of the deadliest infections for hospital patients, has been approved for use by the FDA, one of the first AI-based medical tools to get clearance. The tool detects sepsis hours faster than doctors and has reduced deaths by nearly 20%.

NewsStudy reveals how strawberries and raspberries were ambushed by fungal parasites
Plant diseases often arise when the pathogens that cause disease are introduced into new territories where native plants don’t recognize the pathogen and therefore may have minimal defenses against it. But how often does the reverse happen?

NewsSelf-renewing bacteria offer new hope for heavy metal cleanup
Scientists have revealed a powerful bacterial defense strategy against Cd toxicity. The team found that Stenotrophomonas sp. H225 sheds Cd-laden cell wall fragments and rebuilds new protective layers through a process involving the mtgA gene.

NewsWhat the Andes hantavirus outbreak reveals about pandemic risk
The outbreak of Andes hantavirus aboard the international MV Hondius cruise ship underscores how little scientists still know about the viruses circulating silently in wild rodent populations before they spill into humans.

NewsStudy reveals common mutation linked to autoimmune diseases may protect people from viral infections
New research shows a “risk gene” linked to higher odds of developing autoimmune diseases such as diabetes or lupus may also provide a survival advantage fighting viral infections like coronavirus. The gene PTPN22 carries a mutation, 1858C>T (R620W), found in roughly one in 10 people in North America.

NewsData hidden in tuberculosis screening tests sheds light on patients’ overall mortality
Researchers have uncovered a tool to study immune function of larger populations of patients, using a lab test that physicians already use regularly: tuberculosis screening tests called interferon gamma release assays (IGRAs). It could indicate how well an immune system can mount a response to an array of threats.

NewsResearchers track the mutations that allow HIV-1 to escape broadly neutralizing antibodies
Scientists have established the most comprehensive view to date of how HIV-1 can escape broadly neutralizing antibodies. They have discovered viral mutations that make HIV-1 strains resistant to two bNAbs, 3BNC117 and 10-1074.

NewsThawing Arctic soil awakens only half of soil microbes, new study reveals
A study shows that even after months of thawing, around half of the microorganisms in High Arctic soils remain dormant. This challenges the assumption that warming uniformly boosts microbial activity and carbon release from thawing permafrost.

NewsAnti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA, but viruses can fight back with a molecular trick that stops the scissors from ever being made. A viral “anti-CRISPR” protein sits on the ribosome and jams it as a CRISPR protein named Cas12 begins to form.

NewsMouse study suggests high-fat diets during pregnancy worsen severe GI illness in preterm babies
A new mouse study suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies.

NewsScientists take crucial step in developing world’s first measles treatment
Scientists have characterized human antibodies capable of neutralizing measles virus. These antibodies bind to key sites on measles virus and prevent the virus from entering host cells.

NewsGlobal outbreaks may fuel violence against women — but most cases go unmeasured
Violence against women and girls may increase during infectious disease outbreaks — as economic strain, isolation and disrupted services reshape daily life — yet those impacts remain largely unmeasured, according to a new study.

NewsScientists discover how gut bacteria toxin invades colon cells to trigger cancer
A common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. Researchers have now shown that the B. fragilis toxin BFT must first bind host receptor claudin-4 before it can cause damage.

NewsBoyce Thompson Institute names Dr. Natalie Hoffmann inaugural Jane Silverthorne Postdoctoral Fellow
How do beneficial fungi grow into and through plant cells without destroying them in the process? That question sits at the center of Dr. Natalie Hoffmann’s research – and it’s what earned her the inaugural Jane Silverthorne Postdoctoral Fellowship at the Boyce Thompson Institute (BTI).

News‘Atomic snapshots’ of proofreading enzyme could lead to better COVID-19 drugs
A research team used images generated by a cryogenic electron microscope (cryo-EM) to observe the interplay between SARS-CoV-2 proofreading enzyme exoribonuclease (ExoN) and RNA incorporated with antivirals such as remdesivir, sofosbuvir and bemnifosbuvir.

NewsSeasonal COVID-19 vaccination in 2025/26 reduced risk of illness by half in Canada
An interim analysis estimates that the COVID-19 vaccine for the 2025/26 season reduced the risk of illness in Canada by about half at about 9 weeks after vaccination, offering protection beyond the vaccine’s target strain.

NewsResearchers find diagnostic delays are common for US pediatric patients with malaria
Researchers found that more than one in four pediatric patients treated for malaria in the United States had a delay in their initial diagnosis, increasing the risk of more severe infection.

NewsThe Nexus of Food Systems, Ecosystems and Human Health: Sign up for our fascinating free webinar!
What if health is not produced by humans alone, but co-created with the ecosystems, organisms, and food systems we depend on? A fascinating free webinar will explore how microbes connect people to food systems and the ecosystems that undergird food production.

NewsLight without electricity? Glowing algae could make it possible
Researchers successfully turned on the “light switch” in algae and kept them lit up using simple chemical solutions. The finding opens the door for future technologies such as autonomous robots that can operate in dark environments and living sensors for water quality.
