Here's what to expect during each phase of this week's total lunar eclipse.
A total lunar eclipse occurs when Earth passes between the moon and sun, temporarily bathing the entire lunar disk in its shadow. This in turn causes our natural satellite to glow a deep red, as the scattered light from every sunrise and sunset on Earth is bent onto the lunar disk.Several distinct phases will be on display during the Sept. 7-8 total lunar eclipse, which will be visible in its entirety across swathes of Asia, western Australia and eastern Europe, while other...
New Blood Group System Discovered: MAL
Top Stories Tamfitronics Blood groups are complex. The two best known blood group systems are ABO and Rh. Within each blood group, red cells can carry surface markers called antigens. For example, within the ABO blood group system, there are the A and B antigens — people with A have the A antigen, people with B have the B antigen, people with AB blood have both and people with O have neither.

The new discovery allows identification and treatment of rare patients lacking this...
