At nearly 100 feet long and weighing as much as 170 tons, the blue whale is the largest creature on the planet, and by far the heaviest living thing ever seen on Earth. So there's no way it could have anything in common with the tiniest fish larvae, which measure millimeters in length and tip the scales at a fraction of a gram, right?
A new, large cohort analysis from the prospective Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, indicates that men who had moderate baldness affecting both the front and the crown of their head at age 45 were at a 40% increased risk of developing aggressive prostate cancer (usually indicates a faster growing tumor resulting in poorer prognosis relative to non-aggressive prostate cancer) later in life, compared to men with no baldness.

The first big revelation in conservation sciences was that studying the people on the scene as well as nature conservation was crucial. Now, as this science matures, researchers are showing that it's useful to compare apples and oranges.

Cognitive neuroscience research has shown that certain brain regions are associated with specific cognitive abilities, such as language, naming, and decision-making.
An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain.
Using advanced computer models, neuroscience researchers at the University of Copenhagen have gained new knowledge about the complex processes that cause Parkinson's disease.
Doctors have discovered that patients with a particular genetic variation are four times more likely to develop pancreatitis if they are prescribed a widely used group of drugs.
Heat shock proteins protect the molecules in all human and animal cells with factors that regulate their production and work as thermostats.
The quest to create artificial "squid skin" -- camouflaging metamaterials that can "see" colors and automatically blend into the background -- is one step closer to reality, thanks to a breakthrough color-display technology unveiled this week by Rice University's Laboratory for Nanophotonics (LANP).
Researchers at Case Western Reserve University School of Nursing, who studied the emotional distress of caring for a family member diagnosed with a mental illness, found anxiety is high for the primary caregiver at the initial diagnosis or early in the course of the illness and decreases over time.
A recent guideline for using statins to reduce atherosclerotic cardiovascular disease has wavered too far from the simple cholesterol goals that have saved thousands of lives in the past decade, and doesn't adequately treat patients as individuals, experts said today in a national report.
Calculating the pros and cons of a potential decision is a way of decision-making. But repeated engagement with numbers-focused calculations, especially those involving money, can have unintended negative consequences, including social and moral transgressions, says new study co-authored by a professor at the University of Toronto's Rotman School of Management.
Despite the significant reduction in the overall incidence and death rates from strokes in the United States over the past twenty years, more attention needs to be paid to specific age groups, a recent study found.
