On the move ~ Cell motility, cancer and Nano Medicine

Dr. Kinneret Keren – Understanding how cells move.

It’s women’s basketball in Israel and it’s the top league. There is one minute left for the game and tension rises as Maccabi Haifa gets control of the ball. The other players self assemble, knowing spontaneously the correct configuration for success.  

Dr. Kinneret Keren weaves between the opposition and arrives fully alert beneath the net. The ball is launched towards her; is about to be intercepted by Hapoel Tel Aviv, and with a movement of pure elegance, Keren jumps, scoops the ball and drops it into the net. Success.

If a basketball were a living cell, and if the players in a team looked like DNA assembling itself to meet the needs of the moment, then the coexistence of the career of one of RBNI’s top young scientists with an active role in national basketball would seem natural.

Named one of the 100 top young innovators in 2004 by MIT’s Technology Review magazine, Dr. Kinneret Keren is described by Prof. Erez Braun as a “real star” in the Technion Faculty of Physics, where she set up her lab less than three years ago. She is researching biological self-organization, biophysical aspects of actin-based cell motility, biomimetic systems, and artificial cells.

This research will provide insight for medical science; understanding how a cell moves through space and time can provide important information relevant for  diseases as cancer and heart disease.
In one project, Keren’s lab takes the simplest system – fish skin cells – in order to find out how the cells move with consistent speed and shape. They are also taking on the experimental challenge of mimicking a living cell’s capacity of motility with the ultimate goal of creating an artificial crawling cell. “How numerous molecular building blocks self-organize into a cell that moves through space and time is still not really understood,” says Keren, “It is an open question.”

Keren integrates physics and cell biology in her research, alternating between real and artificial cells. “The biophysical aspects of cell biology have been neglected in many areas,” she explains, “Our research will help clarify the biomechanical processes in relatively simple model systems and will be relevant to more complex cells.”

Cells move by projecting filaments forward and disassembling those behind. This allows cells to be highly responsive to their environment as they are not bound by a rigid shape. “Cell structures can be extremely dynamic,” explains Keren. One project in her new lab looks deeply at what happens to the fluid inside the cell as it moves.

Keren found that fluid flows towards the cell’s leading edge and that this can increase cell speed by as much as 20 percent. “And in different cells under different conditions, it can be even greater,” she explains, “Basic cellular processes are highly relevant to understanding normal processes and diseases. 

For example, understanding how and why cells move faster will help us better understand cancer metastasis.” Nano-biological self-organization is a new field. Working with three RBNI graduate students, Keren uses clean rooms to build microfluidic devices, electron microscopy facilities for studying structures and optical tweezers. Nano infrastructure at RBNI is better and more amenable than what she had at Stanford she says.

The third of four children (all scientists), and mother of three, Keren is delighted to have come to be back at Technion after her post-doc at Stanford. “I had a very soft landing here,” she smiles, “It is very welcoming. For interdisciplinary science, Technion is a very good place. It is a fun place to do research.”

Listen to the wind

Viable, cost-effective energy generated by the power of the wind can already be felt from the north of Israel as faculty member Dr David Greenblatt sets up his revolutionary 175 m2 wind tunnel laboratory at the Faculty of Mechanical Engineering. With a background in aerodynamics and patents for industrial fans under his belt, Greenblatt is well set to fix the problems of friction, performance and shelf-life involved in harnessing the awesome power of the wind.

Harnessing the powers that be: Dr. David Greenblatt

Viable, cost-effective energy generated by the power of the wind can already be felt from the north of Israel as faculty member Dr. David Greenblatt sets up his revolutionary 175 m2 wind tunnel laboratory at the Faculty of Mechanical Engineering. With a background in aerodynamics and patents for industrial fans under his belt, Greenblatt is well set to fix the problems of friction, performance and shelf-life involved in harnessing the awesome power of the wind.

“There are many problems with wind turbine blades,” he explains, “You cannot ‘see’ the wind and therefore you cannot appreciate how it hammers the blades and the whole structure. The wind is unsteady and turbulent, which means the performance drops and design life becomes compromised by high loads. I’m developing flow effectors or actuators that are embedded in the surface of the blades. If I can work out how to use them cleverly, then they will reattach unpredictable flow to the blades, increase the performance of the turbine, and extend the design life of the structure. You are squeezing more power out of the wind… and the same structure might last double the time and need much less maintenance.”

The unique tunnel to test the turbine blades has been designed for optical measurements. Transparent, the tunnel allows Greenblatt’s team to simulate the conditions of nature, measure the wind flow around the turbines with a laser, and optically measure the effects.
“I appreciate GTEP because it gives the opportunity to pursue cutting-edge research,” says Greenblatt who joined the Technion in 2007. “For me it’s exciting. You’re looking at new phenomena, learning about things that haven’t been seen before… It was my dream to build and design this flow-control laboratory.”

The Nano Bible

“The fact that the Bible contains a lot of information – approximately 10 million bits – is central. The Nano Bible project demonstrates the miniaturization at our disposal…”
-Prof. Uri Sivan
 
When Pope Benedict XVI visited Jerusalem in May 2009, President of the State of Israel, Shimon Peres, presented him with a very special gift. Scientists of the Russell Berrie Nanotechnology Institute worked around the clock to prepare the exhibition piece of the world’s first Nano Bible.

The over 1.2 million letters of the Hebrew Bible were etched into a silicon chip at Technion’s Zisapel Nanoelectronics Center, using a focused beam of energetic gallium ions. When the ions strike the target, they splash some atoms out of it, thereby etching into it. A holy speck of dust, the Nano Bible was mounted on a one-centimeter thick transparent stage and presented within an authentic leather cover of a full-sized Bible.

The Nano Bible was created and produced by Prof. Uri Sivan and his doctoral student Ohad Zohar

 
“How small can the Bible be?” Technion Nano students heard the call.
 

 

 

 

The Bible is only 0.5 square millimeters – much smaller than the head of a pin. At  the  Zisapel Nanoelectronics Center the text was etched with a focused beam of energetic gallium ions.

Signifying Technion + NANO: Calatrava Kinetic Sculpture




World-renowned architect Dr. Santiago Calatrava has designed a giant obelisk that marks the heart of the Technion campus. The 28-meter high kinetic sculpture is composed of 224 steel ribs on eight levels. The monument moves in a wave-like motion, in which each moving rib induces the sequential motion of the next one level at a time from top to bottom. “I designed this vertical kinetic sculpture, which integrates beauty with technique and mechanics, such that it can be seen from every place.”


Israel Airforce Article on ASRI: Great Q&A on the future in SPACE education.

This week, the “Technion” celebrates its 99th birthday. If, at its inception, they debated whether to teach in Hebrew or German, today they are figuring out how to launch a satellite to space. The IAF website spoke with Professor Ehud Bachar, head of the Space Research Institute at the Technion, concerning what the university is doing in Space research and where the State of Israel finds itself regarding the field of study

Which Satellite projects are on the Technion’s agenda?
“We are the only university in Israel that has built and that intends to continue building satellites. Today we are beginning a nano-satellite program. Nano-satellites are, essentially, small satellites whose main task is technological checking.

Before we build very large satellites with very advanced instrumentation, we check the technology with a small satellite that weighs just a few kilograms. We are going to open a laboratory that will be used to build such satellites. This initiative is unique to the Technion among Israeli universities and is a continuation of the creation of our original satellite, the “TECHSAT2”. Right now we are talking about a project that is still in its planning stages and has yet to have begun being built.

Additionally, students in our space and aeronautics department are doing a final project that deals with the configuration of nano-satellite’s that should be able to identify a source of radiation on the ground, for rescue purposes. The idea is like this: say a man falls from a boat and assume he has a small transmitter the size of a wrist-watch on him. With the help of this transmitter satellites can provide a precise description of his location. Of course we are talking about operations that satellites already do, but I don’t think anyone else is using the satellite like this.

There are other important aspects of Space research that we are dealing with. For example, we have a patent on an engine named Camilla, that we are developing together with the RAFAEL Company. We also have a propulsion laboratory that we use to check electric engines. This is a national infrastructure that the RAFAEL Company also uses to check engines. We also have another great laboratory for various space systems. There we can do a simulation of a group of satellites, that is to say, how satellites work in groups and conduct tasks together autonomously.

We are just beginning to understand the importance of this field. If we can apply the idea of building nano-satellites, I hope that one day we can conduct demonstration missions like that in Space. Today we do everything in the laboratory: we have robots that go around on tables without friction, simulating two dimensional movements in space, and in doing so we are developing the inspection, technology, surveillance and coordination technologies among the satellites. This is a serious technology that has yet to mature which is why we still don’t use it on a routine basis.

There is another worthwhile thing I should remark on, something we sponsorship: the Space IL Group that is representing Israel in the Google “Lunar X Prize” competition. This group is attempting to build a nano-satellite that will reach the moon. Something like this has never been done before. Beyond the fact that the Technion is sponsoring their work, the university is also providing them with technological guidance. It isn’t clear if it will ever be active, but it would be nice if a small Israeli satellite were successful in getting to the moon and sending pictures. We will have a picture of the Israeli flag on the moon”.

What notable collaborations do you have with the defense industries in space?
“Geographically, we are close to the RAFAEL company, with whom we have continuing projects. For example, we are currently building a satellite named Venus. RAFAEL is building for the first time electric motors for the satellite. This type of motor has never been used in Israel. All of the technology centers that for the most part control the motors of the satellites on route are being built by us with RAFAEL and the aircraft industries.

We have another project with RAFAEL in the field of laser communication. Generally, satellites communicate with each other via radio and our project in collaboration deals with developing a small enough laser system, one that can go on a nano-satellite and can pass information from one satellite to another via laser.

This has great potential because the bandwidth is much greater and much more information can be passed with a laser beam. We are now in the final stages of building a ground system and we want to do a ground trial between two of these systems communicating with one another. One day maybe this will be a functional system that we can put on a satellite.

It is necessary to say that our relationship with the industries has always been and remains tight. Beyond the work on propulsion and collaboration with RAFAEL that I mentioned, in the field of optics we are currently collaborating with El-Op, for example, in the field of remote sensing, specifically with regards to photography of the earth from space. At the end of the month there will be an international conference on remote sensing for agriculture, part of which is done from space. The idea is that with the help of satellite photos, we can let farmers know about spots with large water leaks, lack of irrigation or disease”.


Do you have contact with foreign officials in the field of Space research?

“Space is a difficult field because of military issues. It isn’t simple to collaborate with foreign industries because we are generally talking about government industries with security or other orientations. That isn’t to say that we don’t have the motivation, we would be very happy to further develop international connections and we do this wherever possible. For example, we collaborated on the Galileo program: a large European program whose goal is the creation of a satellite infrastructure for ground positioning, just like GPS. GPS is the American system. Israel is a participating member in this consortium, of which our institute had a small portion, for example in planning satellite routes, with very precise control over the route and more.

One of out goals, clearly, is to greaten the collaboration. We are attractive as a place for training for people from overseas, but with regards to legitimate collaborations, we have what to improve. We are working on it”.

Compared to other countries, where does Israel find itself in the field of Space research?
“In terms of ability in relation to size, Israel would be in first place. Nobody launches satellites with higher performance like we do. Israel’s ability to launch is limited. Our need to have westward launches, that is to say against the rotation of the earth, works against us, and dictates very clear size and weight constraints for satellites.

Even with these constraints, I think Israel’s space capabilities are amazing, really unprecedented. Israel’s satellites weigh several hundred kilograms, and in this sense we have no competitors.

On the other hand, make no mistake: size matters. We don’t have the capabilities that the world powers have with regards to size and frequency of launch. We don’t have the ability to compete with the world’s space giants like the ESA or even with the Chinese. But when it comes to maximum performance despite size, I think we are very good.

In general, the mere fact that we have launch capabilities is impressive because if you look at history, the space industry was grown by world powers that had intercontinental missiles. This was the basis upon which began the capability to launch into space. The number of countries in the world that can even get to Space independently is rather small. In this respect we have much to be proud of”.

Where, then, do we have room to improve in the field of Space research?
“If it were possible to improve launch capabilities and there are efforts in that direction, that is always good. However bigger you can go, the better you can achieve higher performance, but Israel has never gone in that direction. Instead, Israel decided to go with being clever. I’ll demonstrate: in optics, the size of the telescope determines your ability to see, but our optics laboratories are working on all kinds of clever things.

One of the ideas we are tossing around is a telescope that can be spread out in Space. You send it to space all folded up and then you open it in Space. This is not something we invented, rather it is something that is talked about a lot in the world. If we can put into practice this kind of technology, we are talking about a breakthrough, because that means that we aren’t limited in the size of the telescope. Despite this, we still are limited by weight and this is also a challenge: building the telescope from light materials, but stable from both mechanical and thermal perspectives. There is no limit to how much you can improve in Space”.

Simple blood test developed that diagnoses cancer

By JUDY SIEGEL-ITZKOVICH  

10/27/2010 05:03 [Jerusalem Post] 

Researchers of the Technion Institute of Technology claim test will be able to differentiate between different kinds of cancers, tumors, diseases.

An innovative, simple blood test that can diagnose a variety of diseases, including cancer, has been developed by researchers at the Technion-Israel Institute of Technology and was just reported in a central article in the Proceedings of the [US] National Academy of Sciences.

The Technion has registered a patent on the development.



Prof. Arie Admon of the biology faculty claims that the test will provide doctors with a rich variety of information that until now has not been available and is suited to the trend of “personalized medicine,” in which treatment is suited to the genetic and other characteristics of the patient. The development was part of the doctoral work of Dr. Michal Bassani- Sternberg and will help suit medication to the patient.

As opposed to current blood tests for cancer which merely note whether cancerous cells are still in the blood stream, the new test will be able to differentiate between different kinds of cancers and tumors as well as other diseases. Scientists are now working on the technique.

Admon said it was known that when the proteins in a cell deteriorate or end their roles, they are broken down into their building blocks of amino acids to create new proteins. Some of the products of this process, however, are not completely broken down and remain as pieces of short proteins called peptides.

Meanwhile, some of these peptides are displayed on the surface of the cells with help from the human leukocyte antigen (HLA) protein. When the peptides from the proteins of the disease “report” their state of health to the immune system, the immune cells kill the sick cells and prevent the spread of the disease.

The body cells not only present the HLA protein on their surfaces but also release part of these protein molecules into the bloodstream with the characteristic peptides. Cancer cells release larger amounts of the HLA protein with the peptides into the blood in an effort to “confuse” the immune system, explained Admon. Thus, the two Technion researchers reached the conclusion that by characterizing the variety of peptides linked to the HLA proteins that were released into the blood, they could diagnose cancer and other disorders.

The researchers separated the HLA proteins from the other blood proteins and then released the linked peptides. Using a mass spectrometer device, they succeeded in identifying the sequence of amino acids of the separated peptides and the original proteins that were in the cells in which the peptides were produced.

In one blood sample, thousands of different peptides can be identified, providing vital information about the disease or the tumor. There are peptides that are not present in healthy people, and when they are found, the patient can be sent for additional tests, the researchers said.

Making armor for the brain (The story of Moussa Youdim)

[Jerusalem Post: 11/13/2010]

Iranian-born Technion pharmacologist Moussa Youdim has worked for decades on drugs for Parkinson’s and Alzheimer’s disease and even ALS. Judy Siegel-Itzkovich interviews him.

  

PROF. MOUSSA YOUDIM and his wife Fruma. ‘The Nobel



His father’s struggle with deep depression over business troubles in 1957 changed the course of Moussa Youdim’s life, from studying in medical school to going into pharmacology and discovering a cure for that psychiatric disorder. Many patients with Parkinson’s and other diseases are grateful for that shift in the life of this 70-year-old Jew, who as a very active emeritus professor at the Technion-Israel Institute of Technology will next week share with seven others the $1 million EMET Prize for Art, Science and Culture.

The EMET Prize, awarded annually since 2002 for excellence in academic and professional achievements that have far-reaching influence, is sponsored by the A.M.N. Foundation for the Advancement of Science, Art and Culture in Israel, under the auspices of the prime minister. Youdim will receive his prize for brain science in the category of life sciences.

With a surname that comes from the Hebrew word yod’im (know) as his family for over 400 years in Persia were known for their intellectual pursuits, Youdim was given the name Moussa after an official in Teheran’s American Hospital who mistook her for Muslim and told his mother that she must call him Ali. When she protested that she was Jewish, he instructed her to name him Moussa. Since then, even though he is sometimes mistaken for being a Muslim (especially by airport security personnel), he has refused to change it to Moshe.

Warm, outgoing, polite and a man of the world, Youdim holds more than 100 international patents in neuropsychiatric drug development and cardiovascular drugs. He acts as a consultant for several major international pharmaceutical companies, and serves on many national and international scientific and grant-giving committees.

Not only have the contributions of the leading pharmacology researcher been included in many standard text books, but he has published a stupendous 800 scientific articles, edited 45 books, served on the editorial boards of 44 international scientific journals, lectured around the globe and received many national and international awards and several honorary doctorates – most recently the European College of Neuropsychopharmacology LifeTime Achievement Award and election to the Leopoldina Germany Academy of Sciences.

HE GOT used to traveling and managing on his own from a young age. Around his 12th birthday, he was sent to a boarding school in the English city of Brighton, and from there left for Canada to study medicine at McGill University – until his businessman father took sick – when there were no safe medications for depression, Youdim recalls in an interview with The Jerusalem Post. His father was given electroshock treatments in England and felt better, but he had recurrent attacks and was never the same.

Youdim’s mother became the family breadwinner.

In 1960, the only existing antidepressant medication, iproniazid, had been meant for treating tuberculosis, but it was found to make people who took it happier. Yet, it killed some people who took it along with cheese or wine, launching a race to find a safe antidepressant.

After taking courses in bio- and neuro-chemistry, he became enthralled with the idea of understanding how the brain works, and wondered how to fix it. Graduating with a BSc and MSc and then his doctoral degree in biochemistry at McGill’s Allan Memorial Psychiatry Institute, he returned to England for post-graduate work at the University of London and taught at Oxford and at the College de France in Paris.

YOUDIM RECALLED that nearly 40 years ago, he heard a lecture by Holocaust survivor Joseph Knoll about work on an antidepressant called deprenyl. Unfortunately, it wasn’t effective, but it also was not harmful to people who drank wine or ate cheese. A few years later, Youdim and Prof. Peter Reiderer of Austria thought and demonstrated that deprenyl was effective in treating Parkinson’s, the degenerative disorder of the central nervous system that impairs motor skills, cognitive processes and other functions, and whose symptoms include tremor, rigidity and unstable posture, along with cognitive and neurobehavioral problems, dementia and sensory and sleep difficulties.

Deprenyl, later named selegiline in the US, became the first monoamine oxidase B inhibitor for the treatment of Parkinson’s disease. But they found that deprenyl may indeed have side effects; Youdim searched for a deprenyl-like drug that would be more effective. He finally stumbled upon a candidate drug that was in his possession; he developed it into rasagiline (now patented as Azilect and sold by the Israeli company Teva Pharmaceuticals).

Margaret Thatcher’s anti-Socialist tenure as British prime minister annoyed Youdim and other scientists no end – “she was called a ‘milk snatcher’ when she took away free milk supplies for schoolchildren – and though he was happy at Oxford, he became alienated from England.

Simultaneously, Youdim visited Israel (although most of his family ended up in Los Angeles) and was invited to see the Technion’s new medical school, where the dean offered him a job to establish and head a pharmacology department; the only one in Israel then was at the Hebrew University in Jerusalem. “I liked Europe, but I thought Israel would be exciting – and indeed it has been.”

ALTHOUGH ACADEMIC pharmacology is necessary to build the pharmaceutical industry, Israel had few prominent people in the field, and the Weizmann Institute of Science in Rehovot never set up its own pharmacology department because it didn’t regard it as pure but rather applied science. It is ironical that many people at Weizmann now consider themselves drug developers, he adds.

Although he had received enticing offers from the US and Iran, Youdim agreed to come to Haifa to live in 1977. “I had to recruit people for the department and was asked to go to ulpan to learn Hebrew, but I taught in English; I didn’t have the time to learn Hebrew. I was given five years, but I still don’t really speak it,” he admits with some amusement.

He and his first wife had three children – Shai, Tal and Avigail, none of whom went into science – and they later divorced. On a blind date 15 years ago, he met Fruma, a high-school English teacher and mother of two whose Holocaust-survivor parents moved from Austria to Israel when she was two years old. Moussa and Fruma married a decade ago, and – speaking Hebrew like a native and feeling “totally Israeli” – she makes up for his lack of fluency in the language. When not flying around the world together, they live in a penthouse on a hill in Haifa that overlooks much of the city and the sea. After chairing the pharmacology department at the Technion’s Rappaport Faculty of Medicine until 1994, he went on to direct the Technion’s Eve Topf and US National Parkinson Foundation Centers of Excellence for Neurodegenerative Diseases Research and Teaching.

ALTHOUGH HE says he has has never regretted becoming an Israeli, Youdim encountered roadblocks in the bureaucracy and the academic establishment.

“It’s a small country, with one pie, and everybody wants a piece of it. If you didn’t grow up here, you may have difficulty. Politics is important and intertwined with other things.” But, he says, all this can be overcome, and his own success story proves it.

Two years after his arrival, he suggested to Teva – then a small generic medicine producer – that they offer a deal for rasagiline, but officials turned him down. But in 1987, as Teva was beginning to develop original drugs such as Copaxone for multiple sclerosis, Youdim got a call, this time to invite him to establish a unit to work on his Parkinson’s drug along with Technion colleague Prof. John Finberg.

Today, approved by the US Food and Drug Administration, it offers hope to millions of Parkinson’s patients (1.5 million Americans and four million Chinese alone). With annual sales worth $400 million and royalties earned by the Technion and the scientists, Azilect is now being marketed worldwide; it is considered the first neuroprotectivedisease modifying drug for Parkinson’s.

Azilect does not cure the disease, says Youdim, but it has been shown to slow the degenerative process in the brain and has been found in lab studies to actually improve damaged neurons. “The jury is still out. I have nothing to do with clinical studies, but all reports show it helps and has no more side effects than a placebo. There are patients who have been taking it for six or seven years and still benefit from it.”

There are also signs, he says, that a derivative of rasagiline named Cardiamit would help patients suffering from cardiovascular disease, and this is about 20 times more common than Parkinson’s; he has conducted research in this with Technion physiologist Prof. Ofer Binah. This drug is being developed at the Technion’s Alfred Mann Institute.

Asked about implants of electrodes in the brain to alleviate tremors, Youdim says those are not the solution for the large numbers of Parkinson’s patients. A drug is their only hope, as you can’t perform such operations on everyone, he adds.

Youdim has an even bigger target – Alzheimer’s disease. Working with Hebrew University pharmacology Prof. Marta Weinstock-Rosin and Teva, he has developed a new type of drug called Ladostigil (TV 3326), which is now entering Phase II clinical trials in Europe. It integrates rasagiline’s anti-Parkinson benefits with the anti-Alzheimer effects of Weinstock- Rosin’s drug rivastigmine. This is natural, he says, as many Parkinson’s patients also suffer from this dementia disease. The exclusive commercial rights for Ladostigil, which is already the first multi-functional anti-Alzheimer’s drug to reach clinical trials, have been granted to Avraham Pharmaceuticals by the technology transfer arms of the Technion and HU. If everything works out, he believes that Ladostigil will be his second original drug to be put on the market.

Youdim has established the importance of monoamine oxidase and brain iron metabolism for brain function that can lead to cognitive impairments and neurodegenerative diseases. Excessive iron produces oxygen free radicals, which cause degeneration and aging, including brain damage.

Alzheimer’s, he notes, is a very complex, multifactorial disease. “It is not purely neurological; there are probably also some psychiatric aspects, as many patients also have a predisposition to depression.”

More recently he has developed with Prof. Mati Fridkin of Weizmann Institute novel multifunctional iron chelators with monoamine oxidase and cholinesterase inhibitory activity for treatment of amyotrophic lateral sclerosis (ALS or Lou Gehrig disease, a form of which afflicts British theoretical physicist Prof. Stephen Hawking and many others around the world) as well as Lewy Body disease and Type 2 diabetes. “We’ve already published a paper on it, and are working on Huntington’s as well – the familial [genetic] degenerative neurological disease that is even more terrible. I work harder than ever before, even though officially I am retired.” He has been invited twice to Beit Hanassi to see President Shimon Peres, who has asked a group of Israeli neuroscientists to advise him on the establishment of a virtual neuroscience institute linking via Internet a number of research institutions that would collaborate on developing novel approaches to treat neuropsychiatric disorders and benefit the Israeli economy.

As for his native country of Persia, Youdim recalls that in 1978, when he was in Israel, the Shah of Iran invited him to Teheran, decorated Youdim on the monarch’s birthday and gave him a royal medal. “The Soviet Union fell, so fundamentalist Iran could as well. If I were one day invited back, I would visit. It’s a beautiful country.”

Youdim says he hasn’t even asked how much money his share of the EMET Prize will be, but “I don’t care about money; we have enough. I have received so many honors in Israel and abroad that a Nobel Prize is not my goal. There are so many brilliant scientists who have not become Nobel laureates. What is important to me are the many e-mails and phone calls I receive from grateful patients who have been helped by rasagiline. One example was a woman who called at 4 a.m. from Dallas to thank me because her husband had responded to the drug.”

But he will be excited and moved at the EMET Prize ceremony, he concludes. “I will surely think of my father and mother, who meant so much to me. They would certainly be proud.”

Benny and the Jets

By Amanda Jaffe-Katz

“The result is a device that gives you more mileage with less fuel”


Prof. Benveniste (Benny) Natan of the Faculty of Aerospace Engineering is improving rocket or ramjet propulsion performance with a jelly-like substance, based on gasoline. “Gel fuel is a liquid fuel to which you add a gelling agent, and you get something that looks like the Jell-O in your kitchen,” he explains. The addition of metal particles to the gel – analogous to the fruit segments added to Jell-O – leads to much better performance than regular fuel. “We’ve calculated that it’s feasible for a ramjet air-breathing engine, using gel and metal particles, to cover large distances.”


“I address the safety of gel propellants, as well as performance issues,” says Natan. “If the fuel storage tank is hit, then the fuel won’t leak because the gel forms a crust and keeps it in place. Even if it does leak, it’s at a reduced rate – so it’s a safer fuel.”

“With the gel alone, you just get the advantage of safety. For performance, you need the metal particles,” he says. Boron and aluminum are the metals of choice. “You get much more from the metals than from the regular hydrocarbon; the problem is that they sink down in a liquid fuel. But with gel, there is no sedimentation. They stay in place, like the banana stays in Jell-O.”

This, Natan maintains, is a unique solution. “It’s important from every aspect, and there is simply no additional damage to the environment. If you compare with regular hydrocarbon,” Natan explains, “the particles can give you 30 to 40 percent more energy per unit mass when they burn, and sometimes three times more per unit volume. This means you get a more compact motor and save space, and thus reduce the aerodynamic drag. The result is a device that gives you more mileage with less fuel.”


Prof. Benny Natan develops a gel fuel, which is
hydrocarbon plus metal particles, to achieve superior
performance in rocket or ramjet propulsion applications
