Loss of oxygen in bodies of water identified as new tipping point
Oxygen concentrations in our planet's waters are decreasing rapidly and dramatically—from ponds to the ocean. The progressive loss of oxygen threatens not only ecosystems, but also the livelihoods of large sectors of society and the entire planet,.....»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
Respiratory bacteria "turn off" immune system to survive, study finds
Researchers from The University of Queensland have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The research was published in PLOS Pathogens......»»
Stellantis recalls 332,000 vehicles over airbag activation concerns
Stellantis is recalling 332,000 vehicles in the U.S. for an issue with the seat belt connector that could prevent airbag deployment in the event of a crash......»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»

New incompletely rifted microcontinent identified between Greenland and Canada
Plate tectonics are the driving force behind Earth's continental configurations, with the lithosphere (oceanic and continental crusts and upper mantle) moving due to convection processes occurring in the softer underlying asthenospheric mantle. Many.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Newly identified enzyme helps pathogenic fungus build protective cell wall
Researchers at the School of Medicine have identified a novel enzyme involved in building the cell wall of Cryptococcus neoformans, a fungus that causes lung infections and potentially deadly cases of meningitis, primarily in people with AIDS. About.....»»
