Researchers trace evolution to relatively simple genetic changes
In a stunning example of evolution at work, scientists have now found that changes in a single gene can produce major changes in the skeletal armor of fish living in the wild. "Our motivation is to try to understa...MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

Lower bone density appears to recover in adolescent females once they stop using the injected contraceptive depot medroxyprogesterone acetate (DMPA), according to a study funded by the National Institute of Child Health and Human Development of the National Institutes of Health. Previous studies had shown that women who use DMPA, marketed under the brand name Depo-Provera, experience a lo...Of mice and men's (and women's) contraceptives
Mice lacking a special protein found only in germ-line cells results in infertility in both males and females, according to a new study from researchers at the University of Pennsylvania School of Medicine. Norman Hecht, PhD, Professor of Human Reproduction in Penn's Center for Research in Reproduction and Women's Health, and colleagues say that these investigations point the way to a new type of...Critical step traced in anthrax infection
Scientists at Harvard Medical School (HMS) have revealed details of a key step in the entry of anthrax toxin into human cells. The work, which grew out of an ongoing effort to produce a better anthrax therapeutic, shows that the protective antigen component of the bacterial toxin plays an active role in transferring the other two components of the toxin through the cell membrane. The resea...Label IT Tracker CX-Rhodamine Intracellular Nucleic Acid Localization Kit from Mirus Bio Corporation

Lunelle-a monthly injectable contraceptive pill has been approved by the Food and Drug Administration in USA. It is more than 99 percent effective when women get the shot once every month according to the company release marketing the pill. Lunelle is an alternative to another injectable contraceptive called Depo-Provera that lasts three months. It works Like many other birt...Hormone contraceptives lead to bone problems
New research confirms that the main ingredient in the -- depo medroxyprogesterone acetate or DMPA -- can cause significant bone loss when used long term. The younger you are when you begin using this contraceptive, the greater your risk of bone-related problems later in life. // From the time we are born, well into middle age, our bone mass is constantly breaking down and re-buildin...FDA Approves Contraceptive Ring
The U.S. Food and Drug Administration has approved the first hormone-releasing contraceptive implant. NuvaRing, sold by Organon, Inc., effectively blocks conception between 98 percent and 99 percent of the time -- meaning that for every 100 women who use it for a year, only one or two will become pregnant, the FDA says. That rate is similar to both the birth control pill and the yet-unapproved co...Airfuge Ultracentrifuge - For 60 Hz, 120V; with Digital Tachometer
