A new prostate cancer drug, degarelix, has been shown to dramatically reduce testosterone levels in patients as early as three days after treatment. Compared to other treatments, degarelix also resulted in faster declines in prostate-specific antigen (PSA) levels and fewer side effects such as urinary tract infections and joint pains.
A new study reveals that cellular senescence, a natural process for fighting cancer in younger persons, can actually promote cancer in older individuals by triggering the secretion of proteins that cause inflammation. This process is linked to almost every major disease associated with aging, including many cancers.
A Duke University study has found that cats' inefficient gait is actually an adaptation for stealthy stalking, rather than energy efficiency. This means that while dogs rely on efficient four-footed running to catch prey, cats use a slow and deliberate approach to creep up on their unsuspecting victims.
