Cambridge University has achieved a new stem cell research that could allow the first fully "manufactured" baby to be created from the skin cells of two adults of the same gender, opening the door to same-sex couples having their own biological babies.

Researchers from Cambridge University working together with Israel's Weizmann Institute of Science, have paired stem cell lines from embryos with the skin of five different adults, according to the study published in the journal Cell.  The medical experiment had previously succeeded in creating live baby mice, but this is the first study on humans in which the engineered cells created in the laboratory were compared to aborted fetuses to determine an identical match.

In a remarkable new advance against the virus that causes AIDS, scientists from the Scripps Research Institiute in Jupiter, Florida have announced the creation of a novel drug candidate that is so potent and universally effective, it might work as part of an unconventional vaccine.

The research, which involved scientists from more than a dozen research institutions, was published February 18, 2015 online ahead of print by the journal Nature.  The study shows that the new drug candidate blocks every strain of HIV-1, HIV-2 and SIV (simian immunodeficiency virus) that has been isolated from humans or rhesus macaques, including the hardest-to-stop variants. It also protects against much-higher doses of virus than occur in most human transmission and does so for at least eight months after injection.

The World Health Organization(WHO) is to "ramp up" efforts to prevent Ebola spreading beyond the three countries most affected by the deadly virus. Fifteen African countries are being prioritized, top WHO official Isabelle Nuttall told a Geneva news conference. They will receive more help in areas including prevention and protection.

The transmission of the Ebola virus remains intense in Liberia, Sierra Leone and Guinea, the WHO's Dr Nuttall said. There was a "spike" in the Guinean capital, Conakry, said Dr Nuttall, and "intense transmission" in Freetown, the capital of Sierra Leone. In the Liberian capital, Monrovia, she spoke of "significant underreporting" and problems with data-gathering making it hard to reach firm conclusions. But there was a drop in the number of cases in Lofa district.

Scientists believe the findings have finally nailed the origin of AIDS Pandemic to a single source.

A "perfect storm" of factors that came together in colonial Africa early last century led to the spread of Aids in the human population and eventually a full-blown pandemic infecting more than 75 million people worldwide, a study has found. A genetic analysis of thousands of individual viruses has confirmed beyond reasonable doubt that HIV first emerged in Kinshasa, the capital of the Belgian Congo, in about 1920 from where it spread via the colonial railway network to other parts of central Africa.

Yes, dogs can smell cancer. They can even smell it on site and/or at stage zero of the disease.  Why would a dog be interested in smelling cancer? There has to be something in it for them.

Dogs have lived side by side, co-evolving with man for well over 100,000 years. Man provided shelter and food for the dog, and in turn, the dog warned man against impeding danger, pointed towards prey and food, and eventually guarded our livestock and crops. We provided for the dog, and the dog used his nose to help provide for, and protect, us. The key here is that the dog used his nose for our benefit.
