Study reveals new information about how to prevent chronic inflammation from zombie-like cells that accumulate with age In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way. Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as senescence where they persist but no longer divide to make new cells. Our bodies can remove…
University of Arizona neuroscientists studying the brains of songbirds have found that aging alters the gene expressions that control the birds’ song. The finding could lead to earlier diagnoses and better treatments for human neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, which are known to hinder vocal production in their early stages. The study, published in the journal Neurobiology of Aging, found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically…
A new type of antibody which stimulates the immune system to target cancer cells slows tumor growth, according to new research Antibody treatment which activates the patient’s own immune system against cancer, known as immunotherapy, is increasingly being investigated as an alternative for chemotherapy and radiotherapy. This is because it specifically targets the cancer cells, which reduces the side effects seen with more conventional therapies. Tumours, such as some breast and ovarian cancers, can express the marker HER2. HER2 is…
Gemini North’s MAROON-X instrument finds evidence for four mini-Earth exoplanets around our famous cosmic neighbor Barnard’s Star For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth [1]. Barnard’s Star is classified as a red dwarf — low-mass stars that often host closely-packed planetary systems, often with multiple rocky planets. Red dwarfs are extremely numerous in the Universe, so scientists…
