The World Health Organization (WHO) has declared the mpox outbreak in parts of Africa a public health emergency of international concern.
The highly contagious disease — formerly known as monkeypox — has killed at least 450 people during an initial outbreak in the Democratic Republic of Congo.
It has now spread across parts of central and east Africa, and scientists are concerned about how fast a new variant of the disease is spreading and its high fatality rate.
University of Exeter scientists found that common antifungals cause pathogens to self-destruct.
The study reveals that the most common anti-fungals prompt pathogens to undergo self-destructive processes.
The white dwarf’s brightness plunges in a mere 30 minutes—faster than any observed before.
Posted in biotech/medical | Leave a Comment on Gramicidin: Interesting Wikipedia article on gramicidin: a non-ribosomal peptide which can be used as a topical antibacterial (against gram positive bacterial)
Gramicidins work as antibiotics against gram-positive bacteria like Bacillus subtilis and Staphylococcus aureus, but not well against gram-negative ones like E. coli. [ 3 ]
Gramicidins are used in medicinal lozenges for sore throat and in topical medicines to treat infected wounds.s are often mixed with other antibiotics like tyrocidine and antiseptics. [ 4 ] s are also used in eye drops for bacterial eye infections. In drops, they are often mixed with other antibiotics like polymyxin B or neomycin. Multiple antibiotics increase efficiency against various strains of bacteria. [ 5 ] Such eye-drops are also used to treat eye infections of animals, like horses. [ 6 ]

The topic is the mysterious Noctis Labyrinthus — Labyrinth of Night — on Mars! Mars Express is one of the spacecraft investigating it.
Discover why Noctis Labyrinthus could be humanity’s future home on Mars! Join aerospace engineer Mike DiVerde as he analyzes groundbreaking research from three Mars orbital missions that revealed extensive water systems in this equatorial region. Using data from Mars Express, MRO, and Mars Global Surveyor, learn how ancient groundwater shaped this mysterious labyrinth of canyons near the massive Tharsis volcanoes. This comprehensive analysis explains why Noctis Labyrinthus, with its potential subsurface water, caves, and strategic location, might be the perfect site for future Mars colonization. Whether you’re passionate about Mars exploration or curious about humanity’s next giant leap, this evidence-based examination of Mars geology and potential habitable zones will change how you think about settling the Red Planet.

Researchers used a refined method of ancestry analysis utilizing ancient DNA. This study represents a significant advancement in our understanding of historical population movements.
Researchers can trace human migration through DNA changes, but it’s challenging when historical groups are genetically similar.
