On June 9, the Food and Drug Administration approved the first
effective vaccine against Human Papillomavirus, a sexually
transmitted infection that is one of the major causes of cervical
cancer. On the heels of this approval, which represents a crucial
breakthrough in the efforts of scientists, doctors and public
health officials to combat the spread of STDs in the United
States and elsewhere, the Medical College of Georgia announced
today that significant strides have been made towards the
development of another STD vaccine, which will protect against

It has also been recognized since the mid-nineties that some opioid analgesics are more effective in women than men. However, the reasons for these differences have remained a mystery – until now. We know that opioids decrease pain by activating opioid receptors, which are located on nerves that transmit painful sensations. Since levels of mu, delta, and kappa opiate receptors — the three main types of opioid receptor in the brain and spinal cord — are not thought to differ dramatically in men and women, it was difficult to understand why the effectiveness of some painkillers is dependent on sex. Now, researchers at the State University of New York (SUNY) Downstate Medical Center have discovered that the same major types of opioid receptors interact differently, depending on sex . The spinal cord of female laboratory animals was found to contain alm...
