NewsTeam discovers gene pattern that could help doctors identify Ebola faster and more accurately
Researchers have made an important discovery that could help doctors tell Ebola apart from other infections more quickly. The overlap of response by Ebola and other pathogens had made it difficult to find markers that are truly unique to Ebola.

NewsYour nose is a battlefield
Scientists have discovered that FluMist can trigger an immune response directly in nasal tissue in adults. The vaccine trains immune cells in the upper nasal passages to recognize and fight influenza virus infection. This immune response stays in the upper airways and can’t be detected via blood samples.

NewsPortable TB test matches lab accuracy in just minutes
A portable device called MiniDock MTB can deliver accurate TB test results in less than half an hour. Researchers show the device is as effective as a laboratory test and can detect cases even among people who have trouble producing phlegm samples from deep within their lungs.

NewsSimple new system keeps microscopes in focus automatically
Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Now a team of scientists has developed an inexpensive robust fix for this problem that involves little more than a couple of LED lights and some physics-based processing.

NewsNew study suggests seasonal flu vaccines may reduce severity of H5N1 bird flu infections
Researchers have found that seasonal influenza vaccines in routine global use may significantly reduce the risk of death from H5N1 infection. The findings that readily available tools may offer protection while the world races to develop more targeted solutions.

NewsScientists source anti-cancer treatment in bacteria
Researchers have developed an anti-cancer therapy inspired by bacteria found in cancer tumors. The therapy is made from a fragment of a bacterial protein, a peptide called aurB. In cancer tumors in the animal models, aurB prevented energy production in the tumor cells’ mitochondria, essentially cutting off the tumor’s fuel.

NewsDecades-long study finds ‘stable’ soil carbon degrades
After nearly four decades, the world’s longest-running soil warming experiment is revealing a surprising result: even ‘stable’ carbon in forest soils can break down as temperatures rise, releasing more CO₂ into the atmosphere.

NewsLifestyle, diet, and clinical factors shape the gut microbiome in cancer patients
Lifestyle factors, such as physical activity and dietary modifications can beneficially modulate the gut microbiome of cancer patients - however their effects are often shaped by non-modifiable variables.

NewsStick-on gel offers new way to treat and monitor plants
Scientists have developed an adhesive gel that can be loaded with substances, such as small molecule drugs or nanoparticles, and applied directly onto a plant to deliver those materials into its tissues. In tests, a gel loaded with antibiotics cleared a bacterial infection in a plant within about 48 hours.

NewsBeyond outbreaks: zoonotic disease prevention at the human–animal interface in China
A study synthesizes evidence on 93 zoonotic diseases currently monitored by China’s public health, agricultural, and forestry sectors, and argues that meaningful risk reduction will require shifting from reactive outbreak response toward earlier prevention at the human–animal–environment interface.

NewsNew study suggests reduced newborn hepatitis B vaccination coverage may increase infant infections
Researchers found that lower vaccination coverage among infants born to unscreened mothers was associated with a substantial increase in HBV infections.
-
NewsWhere people get their news influences their beliefs about vaccines
People who follow “new right” media outlets are more than twice as likely to be vaccine-hesitant compared to those who never engage with those outlets, a new study finds. Hesitant adults were more likely to rely on non-authoritative sources for health information.

NewsGlobal Virus Network statement on H5N1 vaccine developments
The new vaccine momentum reflects the growing urgency of avian influenza (H5N1) threat and reinforces the need for coordinated global preparedness.

NewsResearchers discover new mosquito-specific viruses
A new study looked at mosquitoes’ immune response to discover many more insect viruses. Researchers hope to someday use the mosquitoes’ own immune system to battle some of the most pervasive and antagonistic human viruses.

NewsAssociation of changes in portal insulin with immunometabolism during and after hepatitis C virus infection
A new study aims to investigate the relationship between insulin, the gut-liver axis, and immunometabolic changes in patients with hepatitis C virus. Lower portal insulin during HCVi is associated with changes consistent with altered pancreatic insulin secretion and decreased hepatic insulin extraction.
-
NewsScientists highlight the cost of delaying childhood vaccination
Delaying hepatitis B vaccination after birth increases infections among newborns and decreases their survival rates and quality of life. A new study found that the longer the delay, the higher the cost in human life and health care.

NewsA universal toolkit for editing bacterial DNA
A major collaboration involving nine labs has transferred a particularly useful DNA editing system from E. coli into 14 new species of bacteria, spanning three major branches of the bacterial family tree.

NewsHow AI can help us count the ‘good’ viruses used in biopharmaceuticals
Researchers have developed a new methodology that uses artificial intelligence (AI) tools to identify and count target viruses more efficiently than previous techniques. The new approach can be used in applications such as pharmaceutical biomanufacturing.

NewsGut microbiota impacts resistance to bacterial pneumonia: Study
A gut-lung connection influences susceptibility to infection by Acinetobacter baumannii, according to a new study. Investigators found that antibiotics disrupt the gut microbiota, suppress protective immune system pathways in the lungs; and increase the severity of pneumonia.

NewsStudy of influenza D in human cells and tissue hints at spillover potential
The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.
