NewsResearchers uncover what could make some bacteria-killing viruses more effective than others
Bacteriophages — or phages, for short — are viruses that kill bacteria, and scientists have been studying them for decades as a possible solution to antibiotic-resistant infections. But phages are notoriously picky eaters — a phage that can eradicate one bacterial strain is often powerless against others, even if the ...

NewsResearchers reveal snapshots of a key molecular machine in tropical parasites
A study reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid parasites, which cause serious diseases in humans, animals and plants.

NewsA shorter, better-tolerated treatment for chagas disease is possible
A 30-day course of benznidazole taken once a day could offer people with chronic Trypanosoma cruzi infection a safer and more practical option than the current standard treatment, taken twice a day for 60 days.

NewsTarget identified in treatment of neuroHIV
NeuroHIV occurs when HIV infection affects the function and structural integrity of the brain and, to some extent, the spinal cord and peripheral nervous system. New research has identified a brain protein driving this damage, pointing toward a possible treatment.

NewsHot spring organism breaks record for heat tolerance of complex life
Scientists describe a new species of amoeba that can eat and reproduce in hot spring water as warm as 63°C (145°F) in California’s Lassen Volcanic National Park. The amoeba can protect itself at temperatures up to 70°C (158°F) by changing shape and forming a protective outer layer.

NewsCould these pills help people with anorexia? A new study aims to find out
A new clinical trial is recruiting people diagnosed with anorexia nervosa as researchers hope to discover if fecal microbiota transplant (FMT) capsules could help better manage this eating disorder.

NewsDirect rescue of segmented negative-sense RNA viruses from complementary DNA in monkey kidney Vero cells
This technology enables the direct rescue of segmented negative-sense RNA viruses from complementary DNA in monkey kidney Vero cells, facilitating safer and more efficient live-attenuated vaccine production.

NewsScientists reveal tissue culture-free (“ex vitro”) transformation method for trees
This technology introduces a novel “ex vitro” transformation method that utilizes Agrobacterium rhizogenes to genetically modify the roots of woody plants without the necessity for tissue culture.

NewsCyanobacterium found in clean lakes shows little toxic potential
Scientists have assembled the first complete genomes of Gloeotrichia echinulata, comparing DNA of samples from both West Coast and Northeast lakes. They found no evidence of the machinery required to produce the toxins commonly associated with cyanobacteria.

NewsHospital expands newborn screening to identify virus that can lead to hearing loss and developmental delays
Researchers have developed a new screening program for congenital cytomegalovirus, the most common infection passed from mothers to babies during pregnancy. While many babies with congenital cytomegalovirus have no obvious symptoms, some can develop hearing loss, developmental delays or other medical complications as they grow.

NewsResearch could lead to better prevention for a common cause of newborn meningitis
A new research project will investigate how Strep B bacteria attach to the vaginal tract and the mechanisms they use to stay there. In newborns, Strep B infections can kill and the study will look at how Streptococcus agalactiae comes to colonize the birth canal in the first place, which may lead to improved preventative measures.

NewsNabsys announces first publication showcasing CRISPR/Cas9 mediated approach to expand the capabilities of electronic genome mapping
This study is the first to demonstrate the potential of combining Electronic Genome Mapping (EGM) with CRISPR/Cas9 to both characterize CRISPR/Cas9 activity and enhance the capabilities of genome mapping.

NewsGut microbiome development may help predict type 1 diabetes in children at high risk
A new prospective study found that children at high genetic risk of type 1 diabetes whose gut microbiome development plateaued early had about three times the risk of developing the disease compared with children whose microbiomes continued to mature.

NewsHow a single viral protein hijacks immune cells to supercharge COVID-19 infection
A new discovery reveals how a SARS-CoV-2 protein reprograms immune cells to accelerate viral spread—and points to a new strategy for therapeutic intervention.

NewsBoosted BCG vaccine strategy significantly reduces tuberculosis relapse
A new study reveals that combining an immunotherapy with the traditional Bacille Calmette-Guérin (BCG) vaccine drastically lowers the risk of TB relapse in preclinical models.

NewsNew sepsis guidelines seek to reduce infection’s deadly toll
Experts have developed important new guidelines to improve care for patients who develop sepsis, a dangerous full-body infection that kills at least 350,000 Americans every year.

NewsLong-acting antibodies may work with the immune system to control HIV and help reduce the reservoir
Results from a clinical trial have offered a new HIV strategy, suggesting that just one or two doses of broadly neutralizing antibodies (bNAbs) can suppress the virus long-term, keeping it at undetectable levels for months and even years.

NewsUS officials suppressed warnings over flawed covid vaccine safety algorithm
US health officials knowingly relied on a compromised algorithm to detect signals of harm from mRNA covid-19 vaccines and silenced efforts to fix it, finds an investigation.

NewsNew test could dramatically speed diagnosis of hard-to-detect lung infections
Nontuberculous mycobacteria can cause chronic, tuberculosis-like lung infections. Researchers have developed a new diagnostic platform that can identify the precise species of bacteria causing a patient’s infection in just a few hours — a dramatic improvement over the current standard, which can take four to six weeks.
