Researchers at the University of Tübingen have shown that the shape of human teeth can be used to reconstruct genetic relationships. Dr. Hannes Rathmann and Dr. Hugo Reyes-Centeno of the University of Tübingen's Humanities Center for Advanced Studies have...
Researchers from the Max Planck Institute for Marine Microbiology in Bremen have discovered a microbe that feeds on ethane at deep-sea hot vents. With a share of up to 15%, ethane is the second-most common component of natural gas....
Scientists are one step closer to adapting the bacteria-killing power of a naturally occurring nanomachine, a tiny particle that performs a mechanical action. In a study published in Nature, a UCLA-led team of researchers describe how the nanomachine recognizes and kills...
Porphyromonas gingivalis is a major bacterial pathogen that leads to periodontitis, also known as gum disease. In Japan, 80% of adults aged 35 and over suffer from this disease. What's more, P. gingivalis has also been linked to rheumatoid...
Scientists believe about 25 percent of the differences in human life span is determined by genetics—with the rest determined by environmental and lifestyle factors. But they don't yet know all the genes that contribute to a long life. A study...
Cells in some of the body's most vulnerable entry routes to bacterial infection buffer themselves when the immune system detects danger by reorganizing the cholesterol on their surfaces, a new study led by UTSW scientists suggests. The findings, published...
Before new drugs can be administered to people, researchers first have to investigate their effects using cell cultures and animal testing. Human cell cultures are increasingly being used as a model system for this purpose. At the Max Planck...
The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the process by looking at...
Research led by the University of Southampton has revealed the fundamental features of the SARS-CoV-2 coronavirus that causes COVID19. The researchers have produced the first model of a spike of the virus which shows how it disguises itself to...
There is plenty of scientific evidence that the health of a mother can impact the health of her child. Now a Northwestern University study flips that relationship around: Researchers have discovered the health of the fertilized embryo determines the...
Timing is everything. A fresh example supporting the old saying has been found in connection with the systems regulated by biological clocks. Research on circadian rhythms, our internal 24-hour patterns that affect sleep-wake and metabolic cycles, has shown that timing is...
