Dr. Stefania Pellegrinelli, the first graduate of the joint double-Ph.D. track at the Technion and the Politecnico di Milano addressed the gathering on behalf of the graduating students. Throughout her studies, whose curriculum was established as part of the cooperation between the Technion and the Italian university, Dr. Pellegrinelli was advised by professors from both institutions and spent a year at each of them, ultimately receiving a Ph.D. from both universities. Dr. Pellegrinelli, who spoke in both Hebrew and Italian, specializes in planning the robotic assembly in production lines, and during her Ph.D. studies designed a robotic production line for a subsidiary of the Italian car manufacturer Fiat. Her advisor at the Technion was Prof. Anath Fischer of the Faculty of Mechanical Engineering.

“I attended a high school that focused on academic studies and my favorite subject was math,” recalled Dr. Pellegrinelli after the ceremony. “For my Ph.D. studies at the Technion I decided to specialize in robotics. The relationship between lecturers and students at the Technion is much more personal and I really enjoyed my studies here.”

Texas & Technion join forces for Water

Texas and Israel’s Technion team up to build water system

California could learn a thing or two about innovative water technologies from university researchers in Israel and Texas, whose joint desalination project won the Honorable Mention award in a USAID competition. A prize of $125,000 grant will be used in the near future to build a groundwater treatment plant in Jordan.

Driven perhaps by a common pioneering spirit or the aridness of their land, researchers at the Technion-Israel Institute of Technology in Haifa, Israel and the University of North Texas teamed up to enter the competition held by USAID— the United States Agency for International Development. The competition’s goal was to develop innovative technology for producing food and potable water in the Third World, using sustainable alternative energy. “By 2050, global water demand is expected to increase by 55%, and 70% of global water use occurs in food production,” said Christian Holmes, USAID Global Water Coordinator.

Researchers at the Technion’s Stephen and Nancy Grand Water Research Institute joined the competition at the request of researchers from the electrical engineering department at the University of North Texas. The American researchers, who focused on developing a solution to the alternative energy aspect of the competition, asked Prof. Carlos Dosoretz and Prof. Ori Lahav, researchers from the Technion Faculty of Civil and Environmental Engineering, to design a solution for the desalination aspect, and to submit a joint proposal. Other researchers from universities in Jordan, Nepal and Brazil also participated in this project.

“Hundreds of proposals from around the world were submitted in this competition,” explains Prof. Ori Lahav, who heads the Stephen and Nancy Grand Water Research Institute, where the desalination system was designed. “At the end of 2014 our proposal advanced to the semi-final stage, along with the proposals of seven other groups.” Six groups participated in the final round, which was held last month in the deserts of New Mexico. The participating teams were given two days to set up a complete, fully operational pilot system, and operate it autonomously for 48 hours to demonstrate its effectiveness in the field.

“The water treatment process was based on an innovative combination of three technologies – reverse osmosis, ion exchange and nano- filtration,” explains Prof. Lahav. “The challenge was to find a solution for problematic water characterized by particularly high concentrations of dissolved calcium and sulfate.” University of North Texas researchers used a combination of wind and solar energy to power the system.

The group in which the Technion participated included the engineer Ran Nahir and Dr. Liat Birnhack, of the Faculty of Civil and Environmental Engineering. The group was placed among the top three winners, making it eligible for $125,000 in financing for the implementation of innovative technologies in the Third World. Massachusetts Institute of Technology (MIT), jointly with Jain Irrigation Systems, won first place.

USAID is a division of the U.S. State Department with financial aid from Sida, the Swedish International Development Cooperation Agency and The Ministry of Foreign Affairs of the Kingdom of the Netherlands.

Harvey Prize Laureate Lectures

Distinguished Professors James P. Allison and Reinhard Genzel awarded Technion’s prestigious Harvey Prize.

Technion President, Prof. Peretz Lavie, awarded the Harvey Prize to Professor James P. Allison, prominent cancer researcher, and Professor Doctor Reinhard Genzel, internationally acclaimed astrophysicist, at a festive awards ceremony held at the Technion. Professor Allison, an immunologist from the University of Texas MD Anderson Cancer Center in Huston, Texas, was awarded the Harvey Prize in Human Health, and Professor Doctor Reinhard Genzel, an infrared and submillimeter experimental astrophysicist from the Max Planck Institute for Extraterrestrial Physics in Germany, was awarded the Harvey Prize in Science and Technology.

The Harvey Prize named after the late Leo M. Harvey (1887-1973), awards each year a sum of $ 75,000 to outstanding individuals who have made significant contributions in the fields of science and technology, human health, and the furtherance of peace in the Middle East. This prestigious prize is considered by many a precursor to the Nobel Prize; 13 Harvey Prize winners went on to win the Nobel Prize. Among them is esteemed Professor Shuji Nakamura who was awarded the Nobel Prize in Physics last December for inventing the blue LED, a major breakthrough in lighting technology.

Professor James P. Allison, who is the Chairman of the Department of Immunology at the MD Anderson Cancer Center, received the Harvey Prize for developing a new paradigm for cancer treatment and for his theoretical and practical contributions to cancer treatment, which transformed the fields of basic and tumor immunology. The MD Anderson Institute, affiliated with the University of Texas, is ranked as one of the nation’s best hospitals for cancer care in the United States.

Prof. Allison, who was born in Texas in 1948, specializes in the field of immunotherapy – treatment by means of strengthening the immune system – particularly in the context of cancer treatment. Allison has a longstanding interest in T cells, which play an important role in the immune system, and his research led him to discover a T-cell inhibitory molecule (known as CTLA-4) which can prevent them from attacking tumors. Following this discovery, Alison developed an antibody to block this inhibitory molecule in the hope that it will enhance anti-tumor immune responses and tumor rejection. His research led to the clinical development of Ipilimumab (Yervoy™), which was approved in May 2011 by the FDA for the treatment of metastatic melanoma. Today, Allison investigates possibilities for applying Ipilimumab and similar inhibitory drugs-treatments in treating other forms of cancer, such as lung, kidney, prostate, intestinal and breast cancer.

In his opening speech, Professor Pertz Lavie described Professor Allison as, “A person of courage and independence, who is not afraid of going against conventional wisdom. In the 1990’s, after the scientific community had all but given up on the idea of cancer immunotherapy – it was Prof. James Allison who kept the flame alive, and eventually succeeded.”

“As a kid I was very curious and always wanted to solve puzzles,” began Prof. Allison in his acceptance speech. “I wanted to be the first to know something that no one else did. I taught myself many subjects and so I got a lot of experience solving puzzles. This is my first visit to Israel and to the Technion, and I was amazed at the high scientific level of researchers and students that I met here. My research stems from my desire to better understand the immune system, and I am very pleased to have developed a drug to help people while on this quest. Doctors tend not to talk about cancer treatment in terms of ‘healing,’ because conventional treatments are always temporary, with cancer having a way of ‘stalking’ a person later on in life. However, there is justification in likening immunotherapy to ‘healing.’ Patients who were treated using our method have reached the 10 year mark, living far longer than the prognosis of a few short months.”

Professor Doctor Reinhard Genzel received the Harvey Prize for showing irrefutable evidence of a massive black hole in the center of the Milky Way (our galaxy) through his development of many nobel ground, airborne and space based instruments that enable the tracking of the motion of stars with unprecedented precision extremely close to the Galactic Center.

Prof. Genzel, who was born in 1952 in Bad Homburg v.d.H., Germany, is a faculty member at the University of California, Berkeley and is the Director at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany. In 2002, Genzel discovered, along with research colleagues in Germany and California, a massive object at the center of the galaxy whose size was smaller than that of the solar system, yet its mass was more than 3 or 4 million than the mass of the sun, in other words, a very massive black hole. This determination was based on the exceptional acceleration of stars surrounding the Galactic Center. Genzel used innovative optical methods and infrared photography to overcome atmospheric disturbances and particles floating in space.

In his opening address, Professor Pertz Lavie shared an excerpt he found to best describe his achievements, “’Prof. Genzel developed instrumentation which enabled him to make outstanding discoveries, including evidence for a massive black hole in the center of our galaxy.’ Think of how amazing that is. We have with us today a scientist who not only made great and important discoveries, but also an innovator who has invented the tools he needed to make those discoveries. A real, twenty-first century Galileo Galilei.”

In his acceptance speech, Prof. Genzel thanked the Technion for this important prize and said, “This is a very meaningful event for me, and I am deeply moved to receive this prize on the year marking the 50th anniversary of diplomatic relations between Germany and Israel. I say this not only because of the past, but also because of the high quality of research and researchers coming out of Israel.

Astronomy is considered to be one of the most ancient sciences, yet the modern tools at our disposal today are expanding our expertise in this field, while pushing forward the frontiers of human knowledge. They allow us to observe, analyze and understand phenomena in space that were previously hidden from our view.”

The Harvey Prize awarded by the Technion was first given in 1972, through the foundation established by Leo M. Harvey from Los Angeles, in order to recognize significant contributions in the advancement of humankind in the areas of science and technology, human health and peace in the Middle East. This prestigious prize has been awarded to scientists from the United States, Britain, Russia, Sweden, France and Israel, among them Nobel Laureate Mikhail Gorbachev, former leader of the USSR, awarded the Harvey Prize in appreciation of his seminal initiatives and policies to lessen regional tensions; Nobel Laureate in Medicine, Professor Bert Sakmann; Nobel Laureate in Physics, Professor Pierre-Gilles de Gennes, Professor Edward Teller for his discoveries in solid state physics, atomic and nuclear energy; and Professor William J. Kolff  for his invention of the artificial kidney.

Learning the Language of Proteins

Assistant Professor Reut Shalgi returned from MIT to Israel thanks to the Technion, where she currently investigates regulatory mechanisms of protein synthesis at the Rapapport Institute of Medical Research.

“As a scientist, I have access to an endless world of research topics. Science leads you in directions you hadn’t initially thought of, and you have to navigate your way through it, but at the same time to let it lead you.”

Assistant Professor Reut Shalgi, who this week was awarded the prestigious Alon Fellowship for Outstanding Young Faculty, joined the ranks of the Technion faculty last year. Currently, as a member of the team at the Technion’s Rapapport Institute of Medical Research, she investigates the mechanisms of translational control by the ribosomes.

She graduated cum laude from Tel Aviv University in 2002, with a double major in Biology and Computer Science. Her final project explored what was back then the emerging field of Bioinformatics, which applies tools from statistics and computer science to biological and pharmacological research.

Thanks to her computer science skills Prof. Shalgi began, while still an undergraduate, to work in the hi-tech company of RadVision. But the search for new challenges led her to enroll in the Life Sciences Master’s degree program at the Weizmann Institute. With the guidance of Prof. Yitzhak Pilpel and Prof. Ron Shamir she used bioinformatical methods to study mechanisms that regulate gene expression – and was captivated by the world of scientific research. “During my Masters I realized I wanted to be a scientist – to understand how cells function, investigate the ways in which they can malfunction and find ways of correcting them.

“We work in the new and fascinating field of systems biology, increasingly integrating biology and computer science, and using genome-wide data and bioinformatical tools,” Assistant Professor Shalgi explains. “Systems biology gives us an broad view of the biological processes taking place inside the cell, whereas classic biology examines these processes in depth.” She went on to undertake her PhD at the Weizmann Institute, with Prof. Pilpel and Prof. Moshe Oren as her advisors. “My research focused then on the regulation mechanisms of micro-RNA – small molecules that are genes but that do not encode proteins. Every stage in protein synthesis is controlled by numerous factors inside the cell. I investigated the interrelationships and the coordination between different levels in this network.”

In 2009, after she completed her Ph.D., Assistant Professor Shalgi went to pursue her post-doctoral studies at MIT. Under bioinformatics expert Prof. Chris Burge and Prof. Susan Lindquist, a world leader in the field of  chaperones (specialized proteins that facilitate the correct folding of other cellular proteins, which is essential for their proper function), Shalgi studied translation control mechanisms in cells under stress, as well as the interrelationship between chaperones and the ribosome. It was at this time that she discovered a previously unknown mechanism of translation control: chaperone-mediated ribosome pausing during the translation process. She continues to research this mechanism in her own lab.

The pausing occurs in response to extreme environmental conditions, and is mediated by the chaperones and their interaction with the ribosome. Upon relief from stress, the essential process of protein synthesis resumes.

“We think that this mechanism is also involved in neurodegenerative diseases, such as ALS, Alzheimer’s, Parkinson’s and Huntington’s diseases, among others,” she adds, “conditions in which proteins misfold and aggregate [accumulate and clump together]. We are currently studying how ribosome pausing is linked to these pathologies.”

She has very good memories of her five post-doctoral years in Boston, during which her first daughter was born – but “I really wanted to come back to Israel, to my family and friends. The Technion gave me a very warm welcome, and last October we returned to Israel – thanks to the Technion. I came back from MIT with several cutting-edge research methodologies, which I brought with me to my new lab at the Faculty of Medicine.”

One of these methods involves high throughput screening of protein-protein interactions performed by a robot, which can screen thousands of protein pairs per day and produce quantitative information on the interactions between each pair of proteins. Assistant Professor Shalgi analyses this data using bioinformatics tools, and maps the control network that governs the cell’s translation system and the interactions among the proteins: “The robot enables me to map out entire protein networks rapidly, and I use bioinformatics tools to analyze the cross-talk between the components in this network, and translation regulators.

“In my lab we integrate biology with genome-wide methodologies and bioinformatics to study the cell as a system. Our unique approach is to look at the cell as a system in which every component must not only function properly on its own but also be coordinated with all other components.”

She never felt that she had to compromise her scientific or research excellence with the move from MIT to the Technion. “The Faculty and the Technion offer me the highest standards possible. It’s a very diverse faculty with a good, strong interface between clinical and scientific research. The Technion’s new major in Medical Sciences offers the Faculty’s students an opportunity to get to know the science and possibly become researchers. Everyone knows what a medical doctor does, but not everyone understands what it means to be a researcher, what it is that researchers actually do on a day-to-day basis. An M.D. treats patients with the tools available to them, but the development of a new drug or treatment requires in-depth understanding of the mechanisms that lead to the disease, and that’s what we as researchers aim for. Some medical doctors manage to do research alongside the clinic, but it’s the full-time researchers who can delve deeply into the processes that cause the disease.”
