Back to the Dead (Sea, That Is)

Unprecedented TAU climate change study digs into half a million years of history

They'll drill through four ice ages, epic sandstorms, mankind's migration from Africa to the New World, and the biggest droughts in history. Tel Aviv University is heading an international study that for the first time will dig deep beneath the Dead Sea, 500 meters (about a third of a mile) down under 300 meters (about a fifth of a mile) of water. Drilling with a special rig, the researchers will look back in time to collect a massive amount of information about climate change and earthquake patterns.

The study, led by Prof. Zvi Ben-Avraham of Tel Aviv University's Minerva Dead Sea Research Center, "aims to get a complete record in unprecedented resolution — at one year intervals — of the last 500 thousand years,” says Prof. Ben-Avraham.

A crazy sandstorm 365,250 years ago?

Looking at the core sample to be dug about five miles offshore near Ein Gedi, the researchers hope to pinpoint particular years in Earth history to discover the planet's condition. They'll be able to see what the climate was like 365,250 years ago, for instance, or determine the year of a catastrophic earthquake.

This is by far the largest Earth sciences study of its kind in Israel. The evidence will help the world's climatologists calibrate what they know about climate change from other geological samples — and may lead to better predictions of what's in store for Middle East weather. For example, are currently increasing dry and hot periods in the region something new, or are they part of some larger cyclical pattern? What they find should also shed light on earthquake patterns — important information for Israelis, Jordanians and Palestinians who live on or around the fault line that passes through the Dead Sea region.

Slicing through a geological cake

"The sediments provide an 'archive' of the environmental conditions that existed in the area in its geological past," Prof. Ben-Avraham says. While the sample being collected isn't as deep as oil explorers drill to look for oil, the core will be something special: it will be kept in an unbroken piece so that records can be traced more accurately.

The study is being supported by the Israel Sciences Academy and includes dozens of scientists from America, Germany, Switzerland, Norway, Japan, and Israel. Scientists from Jordan and the Palestinian Authority are also cooperating on this unique event. The researchers come from a variety of disciplines, from environmental science to chemistry, and each will get different parts of the core to analyze.

Prof. Ben-Avraham himself is particularly interested in chemical changes to the sediment in the Dead Sea over the last half million years. The study, he adds, will shed light on human migration patterns through the region.

At 423 meters, or a quarter of a mile, below sea level, the Dead Sea is the lowest place on earth. Today it draws millions of tourists from around the world to enjoy its legendarily healing properties.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
