Human Skin Cells Have Heen Converted into Fertilizable Eggs for The First Time

Biology, Microbiology /

Scientists announced on Tuesday that, for the first time, they have transformed human skin cells into eggs and successfully fertilized them with sperm in a lab—a breakthrough that could eventually help infertile individuals have children. The U.S.-led team of scientists cautioned that the technology is still many years from being accessible to hopeful parents. However, […]

Parasite Hides by Stealing Human Cell Proteins

Microbiology, Science /

Parasites are infamous for their resourceful ways of infecting human cells, often developing complex tactics to slip past immune defenses unnoticed. One particularly crafty organism, Entamoeba histolytica, has evolved a remarkable method to stay hidden: it tears off fragments of human cells and uses their proteins to disguise itself. Life Cycle of a Deadly Parasite

Microplastics May Build Up in the Brain More Than in the Kidneys or Liver

Microbiology /

A recent study reveals that postmortem brain samples collected last year contain significantly more microplastics than those analyzed nearly a decade ago, suggesting these synthetic particles accumulate in vital organs over time. Researchers led by University of New Mexico health scientist Alexander Nihart found higher concentrations of microplastics in brain tissue compared to kidneys and

Oral Microbes Could Influence Your Risk of Cognitive Decline

Microbiology, Uncategorized /

The bacteria in your mouth affect more than just your teeth and gums—they may also play a role in brain function. A study of 55 people with mild cognitive impairment (MCI) found that those with higher levels of Neisseria bacteria performed better on tests of working memory, executive function, and visual attention. Even among 60

How Bacteria Detect Nearby Death and Gear Up for Combat

Microbiology /

Researchers at the University of Basel have uncovered how bacteria sense environmental threats using a universal danger signal. When nearby cells are dying, bacteria detect fragments of their cell walls, called peptidoglycans, and proactively form protective biofilms. This discovery sheds light on bacterial communication and defense mechanisms, offering insights for combating infections. Sensing Danger: The

Microscopic Fossilized Embryos Unveil Fascinating Insights into Life 500 Million Years Ago

Microbiology, Science /

Tiny mineralized spheres are offering fresh insights into the history of life on Earth. These millimeter-sized fossils, over 535 million years old, are the fossilized embryos of early Cambrian animals. Belonging to the Ecdysozoa group—which includes insects, spiders, crustaceans, and worms—the embryos present a fascinating mystery. While researchers cannot definitively identify their adult forms, Mingjin

Pandrug-Resistant Bacteria Emerging From the War in Ukraine are Highly Pathogenic

Microbiology, Science /

Kristian Riesbeck, a professor of clinical bacteriology at Lund University, was approached by Ukrainian microbiologist Oleksandr Nazarchuk for help in assessing antibiotic resistance in bacteria from severely injured, infected war patients. Using samples from 141 individuals, including 133 adults and 8 newborns with pneumonia, the study revealed widespread resistance to broad-spectrum antibiotics. Alarmingly, 6% of
