Study Shows Last-Minute Role of Protein Named ALIX
University of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or “budding” from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously. (more…)
Could a common sexually transmitted infection boost a man’s risk for prostate cancer?
In a new study, Patricia Johnson, a professor of microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA, explored the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.

A man with almost no hair on his body has grown a full head of it after a novel treatment by doctors at Yale University. (more…)
A class of drug currently being used to treat leukaemia has the unexpected side-effect of boosting immune responses against many different cancers, reports a new study led by scientists at UCL and the Babraham Institute, Cambridge.
The drugs, called p110δ inhibitors, have shown such remarkable efficacy against certain leukaemias in recent clinical trials that patients on the placebo were switched to the real drug. Until now, however, they have not been tested in other types of cancer. (more…)
June is National Men’s Health Month and CPR and AED Awareness Month.
Heart disease is the No. 1 killer of men, and the hearts of one of eight men over age 40 will at some point suddenly stop beating – an event known as sudden cardiac arrest.
June is both National Men’s Health Month and CPR and AED Awareness Month, making it a good time to revisit ways to prevent heart disease. (more…)
Men who keep a mobile phone in their trouser pocket could be inadvertently damaging their chances of becoming a father, according to a new study led by the University of Exeter.
Previous research has suggested that Radio-frequency electromagnetic radiation (RF-EMR) emitted by the devices can have a detrimental effect on male fertility. Most of the global adult population own mobile phones, and around 14% of couples in high and middle income countries have difficulty conceiving. (more…)
UCLA researchers say finding could lead to strategies to reduce risky sex
Like most things, sex requires motivation. An attractive face, a pleasant fragrance, perhaps a sexy image. Yet people differ in their response to sex cues, some react strongly; some don’t. A greater responsiveness to sexual cues might provide greater motivation for a person to act sexually, and risky sexual behaviors typically occur when a person is motivated by particularly potent, sexual reward cues.

“Where does it hurt?” is the first question asked to any person in pain.
A new UCL study defines for the first time how our ability to identify where it hurts, called “spatial acuity”, varies across the body, being most sensitive at the forehead and fingertips.
Using lasers to cause pain to 26 healthy volunteers without any touch, the researchers produced the first systematic map of how acuity for pain is distributed across the body. The experiment, conducted in the group led by Dr Giandomenico Iannetti (UCL Neuroscience, Physiology and Pharmacology), is published in the journal Annals of Neurology and was funded by the Wellcome Trust.
