NewsBat viruses similar to MERS have potential to jump to humans
A group of bat viruses closely related to the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) could be one small mutation away from being capable of spilling over into human populations and potentially causing the next pandemic.

NewsAirborne disease detection made easier with new, low-cost device
A new, small, low-cost device, nicknamed ABLE, could make the collection and detection of airborne hazards much more efficient. ABLE has immediate applications in hospitals, where viruses, bacteria and nanoplastics can be detected directly from the air.

NewsResearch reveals that probiotics slow spread of deadly disease decimating Caribbean reefs
Scientists with the Smithsonian’s National Museum of Natural History have discovered that a bacterial probiotic helps slow the spread of stony coral tissue loss disease (SCTLD) in already infected wild corals in Florida. The findings, published today in the journal Frontiers in Marine Science, reveal that applying the probiotic treatment ...

NewsBacteria hitch a ride on yeast puddles to zoom around
Researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.

NewsStudy resolves diatom tree of life - and could offer clues to Earth’s puzzle
A new study finds that diatoms evolved slowly for the first 100 million years of their existence. Then, 170 million years ago, they reached an inflection point characterized by a burst of rapid speciation orders of magnitude faster than anything that had preceded it.

NewsLarge-scale immunity profiling grants insights into flu virus evolution
A new study has shown that person-to-person variation in antibody immunity plays a key role in shaping which influenza (flu) strains dominate in a population.

NewsStudent discovers long-awaited mystery fungus sought by LSD’s inventor
A student has found a long sought-after fungus that produces effects similar to the semisynthetic drug LSD, which is used to treat conditions like depression, post-traumatic stress disorder and addiction.

NewsNew mRNA vaccine is more effective and less costly to develop, Pitt study finds
A new type of mRNA vaccine is more scalable and adaptable to continuously evolving viruses such as SARS-CoV-2 and H5N1, according to a study.

NewsDNA floating in the air tracks wildlife, viruses — even drugs
A new study reveals the power of DNA, vacuumed up from the air, which can track everything from elusive bobcats to illicit drugs. A simple air filter running for hours, days or weeks can pick up signs of nearly every species that grows or wanders nearby.

NewsNew data shows MMR vaccination rate decline across US
A new county-level dataset reveals a national decline in the measles-mumps-rubella (MMR) vaccination rate among U.S. children since the start of the COVID-19 pandemic.

NewsNew study reveals bats are key players in cross-species spread of morbilliviruses
Researchers studying the spread of morbilliviruses in bats and monkeys in Brazil and Costa Rica have discovered new virus species and host switches from bats to other mammalian species.
-
NewsStudy uncovers how certain antibodies help fight tuberculosis
Researchers collected the largest library of monoclonal antibodies to Mycobacterium tuberculosis (Mtb) and identified specific antibody features that significantly limit its growth.

NewsCotton virus circulated undetected in US fields for nearly 20 years, study finds
A virus responsible for damaging cotton crops has been lurking in U.S. fields for nearly 20 years – undetected. Cotton leafroll dwarf virus (CLRDV), thought to be a recent arrival, was infecting plants in cotton-growing states as early as 2006.

NewsHIV discovery could open door to long-sought cure
Scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding.
-
NewsRock record reveals oxygenation of ocean may have happened earlier than we thought
Researchers uncover evidence that oxygenation in the ocean—crucial for life as we know it—may have occurred earlier than previously thought, offering new insights into the evolution of our planet.

NewsNew diagnostic tool uses bioluminescence to detect viruses
Researchers are shining a powerful new light into the viral darkness with the development of Luminescence CAscade-based Sensor (LUCAS), a rapid, portable, highly-sensitive diagnostic tool for processing complex biological samples.

NewsHow the plague bacillus became less virulent, prolonging the duration of two major pandemics
Scientists have discovered that the evolution of a gene in the bacterium that causes bubonic plague, Yersinia pestis, may have prolonged the duration of two major pandemics. Modifying the copy number of a specific virulence gene increases the length of infection.

NewsResearchers engineer a herpes virus to turn on T cells for immunotherapy
Researchers have identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival - a promising tool in the fight against cancer.
