Iron-Sulfur Cluster Research Offers New Avenues of Investigating Disease

1 year ago American Society for Biochemistry and Molecular Biology 0
Many important proteins in the human body need iron-sulfur clusters, tiny structures made of iron and sulfur atoms, in order to function correctly. Researchers at the National Cancer Institute (NCI), the National Institutes of Health (NIH) and the University of Kentucky have discovered that disruptions in the construction of iron-sulfur clusters can lead to the Read More

Researchers Develop Faster Test for Cannabis Quality

1 year ago University of British Columbia Okanagan 0
With the coming legalization of cannabis in Canada, producers are increasingly looking for quick and accurate means of determining the potency and quality of their products. Researchers at UBC’s Okanagan campus have developed a new method of measuring phytocannabinoids–the primary bioactive molecules in cannabis–that will lead to faster, safer and more accurate information for producers, Read More

Insect gene allows reproductive organs to cope with harmful bacteria

A damaging bacteria with an uncanny ability to pass itself from insect mothers to eggs meets its genomic match in a tiny variety of parasitic wasp, a recent discovery by Associate Professor of Biological Sciences Seth Bordenstein and his team has shown. Offspring of insects infected with the bacteria Wolbachia often die or are converted from male to Read More

Research offers new insights into malaria parasite

1 year ago University of California - Riverside 0
A team of researchers led by a University of California, Riverside, scientist has found that various stages of the development of human malaria parasites, including stages involved in malaria transmission, are linked to epigenetic features and how chromatin—the complex of DNA and proteins within the nucleus—is organized and structured in these parasites. “Our results provide Read More

Scientists analyze first ancient human DNA from Southeast Asia

1 year ago Harvard Medical School 0
The first whole-genome analyses of ancient human DNA from Southeast Asia reveal that there were at least three major waves of human migration into the region over the last 50,000 years. The research, published online May 17 in Science, complements what is known from archaeological, historical and linguistic studies of Southeast Asia, defined as the Read More

New lineage of microbes living in Yellowstone sheds light on origin of life

1 year ago Montana State University 0
Montana State University scientists have found a new lineage of microbes living in Yellowstone National Park’s thermal features that sheds light on the origin of life, the evolution of archaeal life and the importance of iron in early life. Professor William Inskeep and his team of researchers published their findings May 14 in the scientific Read More

Jurassic Fossil Tail Tells of Missing Link in Crocodile Family Tree

1 year ago University of Edinburgh 0
A 180 million-year-old fossil has shed light on how some ancient crocodiles evolved into dolphin-like animals. The specimen – featuring a large portion of backbone – represents a missing link in the family tree of crocodiles, and was one of the largest coastal predators of the Jurassic Period, researchers say. The newly discovered species was Read More

Biologists ‘transfer’ a memory

1 year ago University of California, Los Angeles 0
UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. This research could lead to new ways to lessen the trauma of painful memories with RNA and to restore lost memories.  “I think in the not-too-distant future, we could potentially Read More

Protein Clumps, the Culprit in Alzheimer’s, Also Linked to Heart Failure

1 year ago Kenny Walter | Rdmag.com 0
A group from Johns Hopkins Medicine has found that protein clumping in the heart could contribute to the development of heart failure, similar to how protein clumps accumulate in the brain’s of people suffering from neurodegenerative diseases like Alzheimer’s and Parkinson’s. The researchers identified that the protein desmin tends to clump, and then visualized the Read More

Mitochondria and the art of DNA maintenance

1 year ago John Hewitt | Phys.org 0
Humans have 46 chromosomes, and each one is capped at either end by repetitive sequences called telomeres. If you ask a biologist if humans have circular DNA, they are likely to say ‘no.’ That is because eukaryotic cell nuclei have linear chromosomes, while prokaryotes have circular nucleoids and plasmids. However, biologists also know that most Read More
