To this day, the biopsy is still the gold standard for diagnosing cancer. But there are definite limits to the procedure, one being that you only get a measurement at the time you extract the tissue. A group of scientists at MIT are developing a device that could modernize the way we detect and track the advancement of the deadly class of diseases.

MIT Professor Michael C. Fima and his team have created a prototype of a monitoring chip the size of a grain of rice that would be slipped into the site of the tumor with the same needle that administers biopsies. Once inside the body, the device would monitor tumor activity, as well as the effects of chemotherapy, by creating tiny clumps that can be detected by an MRI. So far, the scientists have tested the prototype on mice; the results are promising.

Gentlemen, put down those blunts. Could it be? A new study suggests that men who smoke marijuana daily are four times more likely to have trouble reaching orgasm than men who don’t. Smokers experience premature ejaculation at almost three times the rate of non-smokers. The experiment, conducted by scientists at La Trobe University in Melbourne, tested 8,656 Australians.

On the bright side, even though male smokers appear to have more problems in bed, they don’t have much problem getting to bed. Pot users were twice as likely to have had two or more sex partners in the previous year than non-smoking men. Female performance doesn’t appear to be affected by the drug.
