DNA defects are linked to cancer and may be primary reasons for aging. However, scientists argue that protein errors are responsible for some negative health changes as well. Researchers at UCL conducted experiments with simple model organisms and found that correcting protein production errors leads to improvements in both health and lifespan. Fruit flies are often used...

OKINAWA INSTITUTE OF SCIENCE AND TECHNOLOGY (OIST) GRADUATE UNIVERSITY IMAGE: THE GRAPH ABOVE SHOWS THAT THE AGE OF A PERSON CAN BE ROUGHLY IDENTIFIED BY MEASURING ONLY FOUR METABOLITES IN THEIR SALIVA. THE BLUE DOTS EACH REPRESENT ONE PERSON IN THE 27-33 AGE GROUP, WHEREAS THE RED DOTS EACH REPRESENT ONE PERSON IN THE 72-80...
UNIVERSITY OF MÜNSTER IMAGE: DIFFERENT TYPES OF WHITE BLOOD CELLS FOUND IN THE OUTER LAYER OF THE MENINGES OF MICE. EXAMINING AROUND 3,000 CELLS, SCIENTISTS ANALYSED WHICH GENES ARE ACTIVE IN EVERY SINGLE CELL AND IDENTIFIED 19 DIFFERENT CELL TYPES. ONE DOT CORRESPONDS TO AN INDIVIDUAL CELL. THE CLOSER THE DOTS ARE TO EACH OTHER,...
by University of Birmingham Credit: CC0 Public Domain New research led by the University of Birmingham suggests that skin cancer patients could have a better prognosis if their T cells send messages from five specific genes in their immune response to drugs given to treat the disease. The research, carried out in mice, cells in the laboratory, and using...

The findings, which also suggest that positive emotional responses to K448 may contribute...
by Howard Hughes Medical Institute Credit: Pixabay/CC0 Public Domain Hundreds of cancer-linked genes play a different role in causing disease than scientists had expected. So-called tumor suppressor genes have long been known to block cell growth, preventing cancerous cells from spreading. Mutations in these genes, scientists believed, thus allow tumors to flourish unchecked. Now, Howard...

by Brigham and Women’s Hospital Credit: Pixabay/CC0 Public Domain Chronic obstructive pulmonary disease (COPD) is a progressive disorder that is often not diagnosed until a patient is over 60 years old and has substantial airflow obstruction. At this stage, it can be difficult to manage and treat the condition. To identify those at risk and intervene...
