New 5 year Metvix-PDT data demonstrate long-term efficacy & reliability for NM skin cancer treatment
...dard treatments.1 In addition Metvix-PDT not only meets the efficacy standards of current treatments but also has significant benefits in relation to compliance, re-treatment, high selectivity, cosmetic aspects including healing.2, 3, 4, 5, 6, 7 The 60 month data in two of the main forms of NMSC showed: ...First demonstration of 'teaching' in non-human animals
...may continue." Tandem running in Temnothorax ants meets all these criteria and thus qualifies as teaching. At the start of a tandem run, the leader finds a nave individual who is willing to follow her. But tandem runs are rather slow because the follower frequently pauses to look round for landmarks so t...Tumor cells that border normal tissue are told to leave
The thin, single-cell boundary where a tumor meets normal tissue is the most dangerous part of a cancer according to a new study by scientists at Washington University School of Medicine in St. Louis. The researchers found that tumor cells bordering normal tissue receive signals that tell them to wan...Carnegie Mellon and University of Pittsburgh receive educational grant from HHMI

There's more than meets the human ear when the black-capped chickadee lets its flock mates know a predator is lurking about by giving out its familiar "chick-a-dee-dee-dee" call.
