The Chinese scientist behind the biggest cloning factory in the world has told AFP that he has technology advanced enough to replicate humans. He said he was just holding off being afraid of the public reaction.

Boyalife Group and its partners are going to build the huge plant in the northern Chinese port of Tianjin, where it will begin production in the coming seven months. The plant is aiming an output of one million cloned cows per year by 2020. However, cattle are just the beginning of ambitions of the chief executive Xu Xiaochun.

There are also thoroughbred racehorses, pet and police dogs, well trained in searching and sniffing, in the factory pipeline.

Paleontologists have discovered a site, which according to them is the largest dinosaur site in Scotland. The site has hundreds of big footprints from plant-eating sauropods, which date back to nearly 170 million years back.

The findings of the footprints and handprints on the Isle of Skye have helped in providing fresh look into the massive, long-necked animals, which were the largest of the dinosaurs. The discovery of a land mammal that fed on plants, has offered the strongest evidence yet that they weren’t afraid to put their toes into the water occasionally.

The Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT researchers have designed and built alterations to the revolutionary CRISPR-Cas9 genome editing system that notably cut down on ‘off-target’ editing errors. The refined technique deals with one of the key technical problems in the use of genome editing.

The CRISPR-Cas9 system functions by bringing an accurately targeted alteration in the DNA of a cell. The protein Cas9 changes the DNA at an area that is specified by a small RNA, with sequence matching the one of the target site.

Though Cas9 is called highly proficient at cutting its target site, the systems main drawback has been that it can attach to and cut extra sites that are not targeted, once it is inside a cell.

When Cho's husband died at his parent's home, shortly after that, his family told her that he had passed away due to AIDS and suggested her to get tested for the same. Cho still remember going to a clinic in heat for getting a blood test done, and breathed a sigh of relief when the test came out negative.

But soon, she began losing weight and started falling sick more often. The former market stallholder has gone for another HIV test in September and it came out positive. While wiping her tears from cheeks, the 43-year-old said that the moment she discovered that she had HIV, she felt very sad.

The biggest manager of prescription drug benefits in the US said that it is going to cover a $1-a-capsule substitute for Daraprim, an anti-parasitic treatment costing $750 per pill, following a hike in the price of the drug by Turing Pharmaceuticals AG from $13.50 this year.

In a statement, Express Scripts Holding Co. said it is going to collaborate with Imprimis Pharmaceuticals Inc., which is a San Diego-based company specialized in compounded drugs.

Imprimis began making a medicine as cheap as $1 per capsule in October. The capsule contains the active ingredient in Daraprim, pyrimethamine, along with a vitamin known as leucovorin that Daraprim is generally taken with.

Scientists are aware of the fact that mutations in the BRCA gene can lead to a higher risk of developing breast and ovarian cancers, since 1994, but this is the first time ever when researchers said that the gene could also play a part in the nerve death that causes Alzheimer’s disease.

Lennart Mucke and his colleagues at the Gladstone institute of Neurological Disease have reported in the journal Nature Communications about their discovery that the BRCA1 gene not just affects the way cells can grow by promoting cancer, but can also interfere with the ability of the nerve cells to repair their DNA.
