NewsScientists discover new phage resistance mechanism in phage-bacterial arms race
Sscientists exploring the complex interactions of microbes in the oral microbiome discovered a new player influencing the phage-bacterial arms race – ultrasmall bacterial parasites, called Saccharibacteria or TM7.
-
NewsScientists link certain gut bacteria to lower heart disease risk
Researchers have identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
-
NewsProcess discovered to undermine bacterial viral Salmonella infection
Study results provide a new understanding of how mammalian hosts defend against pathogenic organisms, as well as implications for better treating Salmonella.
-
NewsSmall protein plays big role in chronic HIV infection
Using a mouse model of neuroHIV, researchers studied the effects of interferon-β (IFNβ), a small protein involved in cell signaling and integral to the body’s natural defense mechanism against viral infections.
-
NewsNew study finds possibility of nitrogen-fixing organelles
Scientists who discovered nitrogen-fixing symbiotic organisms exhibiting behaviors similar to organelles suggest these symbiotic organisms – UCYN-A, a species of cyanobacteria – may be evolving organelle-like characteristics.
-
NewsResearchers develop more broadly protective coronavirus vaccine
Researchers have developed a new vaccine that offers broad protection against not only SARS-CoV-2 variants, but also other bat sarbecoviruses.
-
NewsStudy identifies protein responsible for gas vesicle clustering in bacteria
Scientists have presented the first identification of a protein that can regulate the honeycomb patterning of gas vesicles packed within microbes.
-
NewsWild plants face viral surprise spreading from crops
A new study reveals a previously unknown threat: non-native crop viruses are infecting and jeopardizing the health of wild desert plants.
-
NewsSynthetic material could improve ease and cut cost of gut microbiome research
A team of researchers has developed a new synthetic material that could enable scientists to more easily study how microorganisms interact with the gastrointestinal (GI) system.

NewsMore than 18,000 excess TB cases in the U.S. attributable to structural racism
A robust analysis of national tuberculosis (TB) surveillance data found continuing, persistent disparities in TB incidence among U.S.-born racial and ethnic minorities, despite an overall decrease in cases observed during the analysis period.

NewsProbiotics in kombucha mimic fasting and reduce fat stores in worms
In a new study, researchers found that the microbes in kombucha tea make changes to fat metabolism in the intestines of a model worm species that are similar to the effects of fasting.
-
NewsTB vaccine may enable elimination of the disease in cattle by reducing its spread
Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds.
-
NewsWild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations.
-
NewsA combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis
Scientists repurposed approved drugs that they originally tested to normalize blood vessels surrounding tumors to improve drug delivery to cancer cells.
-
NewsMore older adults being diagnosed with STIs such as gonorrhoea and syphilis
STIs in Americans aged 55 to 64 years have more than doubled over the past decade; in England the number of over 45s diagnosed with gonorrhoea and syphilis doubled between 2015 and 2019.
-
NewsNew enzymatic cocktail can kill tuberculosis-causing mycobacteria
A new study shows that an enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis.
-
NewsResearchers identify microbes that help plants thwart parasite
Researchers have shown that soil microbes induce changes in sorghum roots that make the plant more resistant to infection by witchweed. They identified specific strains of bacteria that trigger these resistance traits and could be applied as a soil ’probiotic’.
-
NewsImplantable device delivers HIV antiviral with more potency than oral drugs
A study shows that a nanofluidic implant delivered an HIV drug that achieved more potency than other forms of drug administration (oral) and other HIV drugs.
-
NewsNew testing approach improves detection of rare but emerging Powassan virus spread by deer ticks
Researchers have come up with a new, more accurate method for detecting in ticks the emerging Powassan virus, which can cause life-threatening neuroinvasive disease, including encephalitis and meningitis.
-
NewsResearchers a step closer to a cure for HIV
A new study demonstrates that a patented therapeutic candidate, an HIV-virus-like-particle (HLP), is 100 times more effective than other candidate HIV cure therapeutics for people living with chronic HIV on combined antiretroviral therapy (cART).
