NewsRising measles cases highlight gaps in vaccination coverage and public health system vulnerabilities
The Global Virus Network (GVN) is closely monitoring a significant resurgence of measles in the United States and globally, reflecting a growing vulnerability in public health systems.

NewsCDI breakthroughs lead to new drug development deal for deadly NTM bacteria
Scientists have developed new compounds against non-tuberculous mycobacteria which are now the subject of a new collaboration and license agreement with the Switzerland-based and publicly listed BioVersys AG.

NewsEarly immune responses linked to protective HIV antibodies
In a new study of broadly neutralizing antibodies and their potential for an HIV vaccine, researchers analyzed fragments of cell-free RNA and DNA circulating in the blood. This makes it possible to track immune responses, viral genetic variation, and other microbes from the same blood sample.

NewsMillions suffering needlessly with curable hepatitis C, new analysis reveals
Millions of Americans are still battling potentially deadly hepatitis C even though they could be cured with antiviral drugs they are not receiving, a new analysis reveals.

NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsConnected habitats help wildlife fight disease, strengthen protective microbes
Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. A new study found that amphibians in connected natural forests and aquatic habitats were more likely to host beneficial skin microbes that inhibit a deadly fungal pathogen.

NewsSome resilient fungi might survive the long voyage to Mars
Researchers recently identified fungi in samples from spacecraft-associated environments, including cleanrooms. Conidia grown from those fungi survived after exposure to simulations of the harsh conditions of Mars and space travel.

NewsScientists map how HIV hijacks human cells—and how cells can fight back
Scientists have opened a new door to understanding HIV by creating the first comprehensive genetic roadmap of how the virus interacts with real human cells. They identified a multitude of hidden players in HIV infection, human proteins that either help the virus thrive or work to stop it.

NewsSevere childhood malaria linked to cognitive impairment later in life
New findings suggest children who survive cases of cerebral malaria and severe malarial anemia experience cognitive and academic impairment that persists into adolescence.

NewsStudying two very different viruses helps to develop new strategies
When the SARS-CoV-2 pandemic began, virologist Theodora Hatziioannou, in conjunction with Paul Bieniasz brought her HIV-honed skills and tools to this new global threat, which made it easier and faster for researchers to gain insights into the virus and test antibodies for potential therapeutic candidates in real time.

NewsResearchers come up with novel strategies for coral restoration
Scientists have discovered a new way to help lab-grown baby corals survive through the early life stage. If young mountainous star corals are grown on cement tiles formulated with sodium carbonate, which raises the alkalinity of the water, they survive much better than the average lab-grown corals.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.
-
NewsEngineered dual-bacterial sensors turn chemical signals into electricity
Most bacterial information transmission is done via electricity. While electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Researchers recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system.
-
NewsSleep deprivation disrupts gut microbiota, worsening colorectal cancer outcomes
Researchers have found that the gut microbiota drives changes to the immune system caused by chronic sleep loss. These changes promote cancer progression, disrupt circadian rhythm and weaken the effectiveness of chemotherapy.

NewsAndes volcanoes – the missing link between algae blooms, whales and climate millions of years ago
Record volcanic eruptions in the Andes could explain the mysterious death of dozens of whales about 5 to 8 million years ago, according to a study. A significant increase in volcanic activity in the Andes peaking between eight and four million years ago likely delivered a significant pulse of nutrients to the Southern Ocean.

News To thwart pathogens, researchers are giving beneficial microbes what they really want
Researchers have developed a new method that allows precise modification of any microbiome with prebiotics, helping beneficial organisms outcompete dangerous pathogens.
-
NewsResearchers uncover a ‘treasure trove’ of bioactive molecules in coral reefs
Researchers have found that coral reefs are home to a vast array of previously unknown bioactive metabolites — small biomolecules that have the biotechnological potential to provide the basis for new drugs, and a host of other products.

NewsSeasonal cycles - even in the depths - sustain ocean microbial biodiversity
Oceanographers discovered that microbial communities–from the sunlit surface to extreme depths–in the North Pacific Subtropical Gyre exhibit robust seasonal cycles. The study provides new insight into how high levels of biodiversity are maintained in the open ocean.
