Scientists make a surprising discovering while studying hundreds of bird species.


How do you like your eggs? Scrambled, sunny side up, hard-boiled, over easy?

If you're one of the distinguished scientists studying the diversity in shapes and sizes of eggs, your answer might be somewhere in the area of "pointy, oblong, asymmetrical, coneheaded."

Those scientists – who hail from the U.K., the U.S., Israel and Singapore – have hatched some pretty revealing conclusions from studying more than 1,400 species of birds to determine how their eggs developed their unique shapes and sizes. For example, why are the eggs of brown hawk owls almost perfectly spherical, while those of the common murre and sandpiper are shaped more like teardrops?

Plants have been used for their medicinal powers for centuries. Now a farm in Zippori is cultivating these plants for sale all over the world.


Plants have been utilized for their medicinal powers since ancient times. Today such plants are shedding their “alternative healing” label, as researchers are analyzing and quantifying their properties, and as more and more allopathic medical doctors are incorporating them into their healing practices. 

Roni and Peretz Gan run the SupHerbs farm in Zippori, not far from Nazareth. Established in 1986, the company has been cultivating medicinal plants for Israel and for export since 1990.

Turns out humans have been harming the planet for a very, very long time.


Long before industrialization and fossil fuels and ocean acidification, humans were undergoing an epic transition from hunting and gathering to agriculture and settlement, the result of which was a massive increase in population.

It was 11,500 years ago, according to Israeli researchers who just conducted a major geological study of the Dead Sea and found erosion rates that they call "dramatically incompatible with known tectonic and climatic regimes of the period recorded."

In other words, humans have been destroying the environment a whole heckuva lot longer than we thought.

A new dig made some fascinating discoveries about the menus of a 2,000-year-old civilization.


Thanks to a huge discovery in Jerusalem, we now know what members of an ancient Mediterranean civilization ate for dinner.

A massive archaeological dig at the site of an ancient landfill in Israel turned up thousands of animal bones believed to have come from sheep and goats, Tel Aviv University archaeologists said. In all, 12,000 bones were found, and they were able to identify 5,000 of them. They also found smaller amounts of chicken and cow bones, in addition to remnants of figs and dates.

Israeli and American researchers develop novel membrane filtration methods to fill a critical need worldwide.


A team of Israeli, German and US researchers have developed novel ultrafiltration membranes that significantly improve the process of removing viruses from treated municipal wastewater used as drinking water by cities suffering water shortages.

The new approach for virus pathogen removal was developed by a team from Ben-Gurion University of the Negev (BGU), University Duisburg-Essen, Germany, and the University of Illinois at Urbana-Champaign (UIUC).

“This is an urgent matter of public safety,” the researchers said. “Insufficient removal of human adenovirus in municipal wastewater, for example, has been detected as a contaminant in US drinking-water sources, including the Great Lakes and worldwide.”
