NewsScientists fight drug-resistant parasites with nature-inspired drugs
As parasites become increasingly resistant to existing drugs, researchers are working to develop a new generation of treatments for two serious infectious diseases: malaria and babesiosis.

NewsRedistributing sunlight boosts algae biomass productivity sixfold
Researchers have developed a low-energy way to distribute sunlight more evenly throughout algae cultivation systems. The technology increased algae biomass productivity by as much as six times in outdoor testing.

NewsBioactive metabolite boosts HIV treatment response, reverses gut dysfunction
Scientists have identified a naturally occurring metabolite that repairs gut damage caused by HIV infection and significantly improves the effectiveness of antiretroviral therapy in the nonhuman primate model of HIV/AIDS.

NewsGeology: Antarctica’s Blood Falls reveals an ancient marine community
Salty water flowing through Antarctica’s Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin.

NewsTwo deadly flowers have big medical potential
Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests. For the first time, researchers have discovered a way to recreate these powerful compounds in the lab - with the help of yeast.

NewsThe amino acid arginine helps the body fight tumors and viral infections
Scientists have discovered that an arginine-deficient diet impacts the immune system by stalling the production of the MHC-1 protein, which alerts the immune system to dangers such as a mutating cell or an invading virus.

NewsScientists bring Florida high school students to the front lines of pandemic preparedness
Thirty outstanding high school students from 18 communities across Florida arrived in Tampa last week for the Global Virus Network (GVN) Global Guardians for Pandemic Preparedness Program, curious about viruses and considering careers in science.

NewsTuberculosis drug discovery gets smarter with AI
Scientists have built an artificial intelligence tool to help scientists focus their efforts after initial screening of potential tuberculosis drugs. The team is also using AI to organize years of collaborative data into a searchable form.

NewsLeaky gut might make food allergies worse
A “leaky gut” might increase the severity of food allergies, according to new research conducted in mice and published in The Journal of Immunology. The researchers found that changes to the gut microbiome in mice were linked to increased intestinal permeability (leaky gut), and an increase in food allergy severity. ...

NewsRock-eating fungi flourish deep below our feet
A new study is believed to be the first time fungal abundance has been successfully quantified in a deep subsurface site. It identified 689 unique species of fungi, including 13 species that have not been described before, in water samples drawn from gas well sites.

NewsHow bats tolerate viruses: study sheds light on one of nature’s biggest immune mysteries
Researchers have found that the world’s largest family of bats has two distinct copies of the genes that produce antibodies, the specialized proteins that help the immune system recognize and fight infections. Every other known mammal has only one such set.

NewsClimate change is redrawing the malaria map in Africa, study finds
A study quantifying climate change’s historical and future impact in sub-Saharan Africa’s children finds that climate change has slightly increased malaria overall. Rising temperatures could increase the malaria risk in southern and East Africa while reducing it where it is most rampant today.

NewsResearch study investigates how maternal viral infections shape lifelong immune health in offspring
A $2.4 million grant will support research that aims to uncover how viral infections during pregnancy reprogram the developing immune system of the fetus, influencing susceptibility to infectious diseases throughout life.

NewsNIH grants $2.8M to develop tools for study of mosquito-microbe interactions
Researchers will use the funding to develop new tools to investigate the genetics underpinning the relationships between mosquitoes and various microbes.

NewsElephant vaccine shows first signs of protection against deadly virus
Scientists have published the first peer-reviewed evidence that an experimental mRNA vaccine may help protect young Asian elephants from elephant endotheliotropic herpesvirus, one of the deadliest diseases facing the species.

NewsTissue-resident immune cells defend human lungs from viral, bacterial, and fungal infections
A study shows that human lung tissue serves as a “reservoir” for a large number of tissue-resident memory T cells.. These cells stand ready to combat a surprising range of viruses, bacteria, and even deadly fungal pathogens.

NewsRemdesivir for COVID-19 linked to better outcomes for adult kidney transplant recipients
Adults with kidney transplants who were treated for COVID-19 with the antiviral remdesivir within a week of diagnosis were less likely than kidney transplant recipients who did not receive the antiviral to experience cardiovascular or kidney problems up to a year later.

NewsBugs as drugs: Engineered gut bacteria show promise against pancreatic cancer
Cancer immunotherapies have transformed treatment for many cancers, but pancreatic cancer remains especially difficult to treat. One major reason is that pancreatic tumors often create a “cold” tumor microenvironment, where the tumor prevents immune cells from mounting a strong attack. In a new study published in Science ...

NewsResearch on foul odors and open wounds targets flesh-eating screwworm
Scientists are studying foul-smelling substances to figure out what attracts the New World screwworm to its favorite meal – open wounds – to develop better lures for trapping this serious threat to the livestock industry.

NewsAI and robotics accelerate search for better gut microbiome therapies
Biomedical engineers have demonstrated a method for systematically developing novel, complex combinations of probiotics and prebiotics to more effectively maintain gut health and treat various gastrointestinal diseases.
