The adult human heart is about the size of a large fist, divided into four chambers that beat in precise harmony about 100,000 times a day to circulate blood throughout the body. That’s a very dynamic system, and also a very challenging one to study in real-time in the lab. Understanding how the heart forms within developing human embryos is another formidable challenge. So, you can see why researchers are excited by the creation of tiny, 3D heart chambers with the ability to exist (see image above) and even beat (see video below) in a lab dish, or as scientists  say “in vitro.”

BBC censors ‘Jewish’ from IS affiliate’s claim of missile attacks

BBC Watch

Despite its defined purpose of building “understanding of international issues”, the BBC has to date done little to inform its audiences on the topic of the approach to Israel prevalent among the Middle East’s rising force of Islamist Jihadists. Hence, one feature of an article which appeared on the BBC News website’s Middle East page on July 4th under the headline “IS affiliate in Egypt claims rocket attack on Israel” is particularly notable.Sinai attacks

Readers were told that:

“A group affiliated with Islamic State has said it fired three rockets into Israel from Egypt’s Sinai peninsula.

The affiliate, which calls itself Sinai Province, said it had acted in retaliation for what it says is Israeli support for the Egyptian army.

Israel said two rockets landed in the south of the country, causing no casualties or material damage.”

Although the third missile was also found in Israeli territory on July…

Translators to Arabic and Korean

The Temple Mount Sifting Project

In about two weeks we are going to launch a new crowd funding website to support the research and publication of the more than half a million archaeological finds from the Temple Mount that we have uncovered so far. In addition to the funding goal; this website will also tell the world the story of the Temple Mount Sifting Project. So far we have translated this website into 13 languages! We are now searching for translators into Arabic and Korean. If you know any suitable translators for this task we’ll appreciate references to
