NEW HYDE PARK, NY – A recent study by investigators from LIJ Medical Center demonstrated that using magnetic resonance imaging (MRI) in men with an elevated prostate specific antigen (PSA) resulted in a prostate cancer detection rate that was twice as high as data reported in the March 1999 Prostate journal that analyzed men undergoing the standard 12-core biopsy with an elevated PSA. Physicians in the recent trial used a targeted approach to evaluate prostate cancer that combines MR imaging and transrectal ultrasound fusion guided prostate biopsy.

Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System's total mass; it generates about 400 trillion trillion watts of power per second; and it has a surface temperature of about 10,000 degrees Celsius. Yet for a star, it's a lightweight.

Drug-resistant bacteria annually sicken 2 million Americans and kill at least 23,000. A driving force behind this growing public health threat is the ability of bacteria to share genes that provide antibiotic resistance.

Bacteria that naturally live in the soil have a vast collection of genes to fight off antibiotics, but they are much less likely to share these genes, a new study by researchers at Washington University School of Medicine in St. Louis has revealed. The findings suggest that most genes from soil bacteria are not poised to contribute to antibiotic resistance in infectious bacteria.

Researchers have uncovered how proteins found in our blood can reduce damage caused to blood vessels as we age, and in conditions such as atherosclerosis and arthritis.

Calcification is a major risk factor for heart attack and stroke. Blood vessels can harden as calcium phosphate (CaP) crystals, normally found in bones and teeth, build up in soft tissue as we age or as a result of illness. This can lead to complications in patients with atherosclerosis, a major cause of death in the UK whereby arteries thicken and are at risk of becoming blocked.

However a team of scientists at the BBSRC-funded Babraham Institute has discovered how CaP damages vessels, and how proteins normally found in our circulation can help prevent this process.

Counterfeit medicines have skyrocketed in recent years and the gullibility of the public has been bolstered by conspiracy theories about profits by pharmaceutical companies - they believe that every country must be making the same products free, or at least subsidizing it to get costs down. A $1 Viagra pill is believable if you want to believe.

A new genetic study has revealed that populations of humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought, and should be recognised as separate subspecies. Understanding how connected these populations are has important implications for the recovery of these charismatic animals that were once devastated by hunting.
