Teenagers who love chewing, smacking and bubble-popping gum may be giving themselves a headache, according to research by Dr. Nathan Watemberg of Tel Aviv University-affiliated Meir Medical Center. His findings, published in Pediatric Neurology, could help treat countless cases of migraine and tension headaches in adolescents without the need for additional testing or medication.

Dr. Watemberg noticed at Meir’s Child Neurology Unit and clinics that many patients who reported headaches were daily gum chewers. Teenage girl patients were particularly avid chewers — a finding supported by previous dental studies.

He asked 30 patients between six and 19 years old who had chronic migraine or tension headaches and chewed gum daily to quit chewing gum for one month. After a month without gum, 19 of the 30 patients reported that their headaches went away entirely and seven reported a decrease in the frequency and intensity of headaches. To test the results, 26 of them agreed to resume gum chewing for two weeks. All of them reported a return of their symptoms within days.

“Out of our 30 patients, 26 reported significant improvement, and 19 had complete headache resolution,” said Dr. Watemberg. “Twenty of the improved patients later agreed to go back to chewing gum, and all of them reported an immediate relapse of symptoms.”

Aspartame, a common ingredient found in sugarless gum, has long been suspected of causing neurological damage. Prior to the European Food Safety Authority recently declaring the artificial sweetener as safe, studies have suggested it may provoke headaches in susceptible individuals. However, the Israeli researchers believe that the amount of aspartame released in gum is likely to be low because the flavor of gum is typically lost after the first few minutes of chewing. Rather, they believe the likely reason for the link between gum-chewing and headaches is the stress on the TMJ.

“Every doctor knows that overuse of the TMJ will cause headaches,” Dr. Watemberg said in a statement. “I believe this is what’s happening when children and teenagers chew gum excessively.”

A possible explanation for the association that exists between chewing gum and headaches is the stress placed on the temporomandibular joint (TMJ), where the skull and jaw meet. Chewing gum causes unnecessary wear and tear of the cartilage that acts as a shock absorbent in the jaw joints, which can lead to pain and discomfort, Dr. Ben Kim, who is not not involved in the study. told the website Medical Daily.

Gum chewers use eight different facial expression when they chew. If used excessively, this can create chronic tightness in two of these muscles that are located near an individual’s temples. Therefore, the nerves that are on this area of the head feel extreme pressure, which can lead to chronic, reoccurring headaches.

A study of fossil pollen particles in sediments extracted from the bottom of the Sea of Galilee has revealed evidence of a climate crisis that traumatized the Near East from the middle of the 13th to the late 12th century BCE. The crisis brought about the collapse of the great empires of the Bronze Age.

“In a short period of time, the entire world of the Bronze Age crumbled,” explains Tel Aviv University archaeologist Prof. Finkelstein. “The Hittite empire, Egypt of the Pharaohs, the Mycenaean culture in Greece, the copper producing kingdom located on the island of Cyprus, the great trade emporium of Ugarit on the Syrian coast and the Canaanite city-states under Egyptian hegemony – all disappeared and only after a while were replaced by the territorial kingdoms of the Iron Age, including Israel and Judah.”

The researchers drilled through 300 meters of water in the heart of the Sea of Galilee and retrieved a core of sediments 20 meters long from the bottom of the lake. The goal was to extract from the sediments fossil pollen grains.

“Pollen is the most enduring organic material in nature,” explains Finkelstein’s colleague Dr. Dafna Langgut, who carried out the actual work of sampling. “Pollen was driven to the Sea of Galilee by wind and river-streams, was deposited in the lake and was embedded in the under-water sediments. New sediments that are added annually create anaerobic conditions which help preserve the pollen particles. These particles tell us about the vegetation that grew in the vicinity of the lake in the past and therefore testify to the climatic conditions in the region.”

The chronological framework of the sediment core was established by radiocarbon dating organic materials that were preserved in the sediments. The counting and the identification of the pollen grains revealed a period of severe droughts between ca. 1250 and 1100 BCE. A core of sediments from the western shore of the Dead Sea – also studied by the research group – provided similar results.

“The advantage of our study, compared to pollen investigations carried out at other locations in the Near East, is in the unprecedented resolution of a sample about every 40 years,” says Prof. Finkelstein. “Pollen is usually sampled in a resolution of several hundreds of years, and this is indeed logical when one is interested in prehistoric matters and glacial and inter-glacial cycles. Since we were interested in historical periods, we had to sample in denser resolution; otherwise a crisis such as the one at the end of the Bronze Age would have escaped our attention.”

Another novelty in the current research is in the chronological correlation between the pollen results and two other records of the past. At the end of the Bronze Age many Eastern Mediterranean cities were assaulted and destroyed by fire. The dates of these events indeed fall between ca. 1250-1100 BCE. The same holds true for ancient Near Eastern written documents that testify to severe droughts and famine in exactly the same period. Such documents are known from across the entire region – from the Hittite capital in Anatolia in the north, via Ugarit on the Syrian coast and Aphek in Israel to Egypt in the south.

Reduction in precipitation in the “green” areas of the Near East should not be expected to cause the collapse of great empires.

So what had happened?

Prof. Ronny Ellenblum of the Hebrew University in Jerusalem studied written documents that describe similar conditions – of severe droughts and famine – in the 10th‒11th centuries CE. He showed that in the northern parts of the Near East, such as northern Iran and Anatolia, shrinkage in precipitation was accompanied by devastating cold spells that destroyed crops. Langgut, Finkelstein and Litt propose a similar process for the end of the Bronze Age: Severe cold spells destroyed the crops in the northern parts of the ancient Near East and shrinkage in precipitation damaged agricultural output in the eastern steppe parts of the region.

This brought about the droughts and famine so well-described in the ancient texts, and motivated “large groups of people to start moving to the south in search of food,” says Egyptologist Shirly Ben-Dor Evian of the Department of Archaeology at Tel Aviv University.

Tel Aviv University researchers didn’t have an immediate diagnosis for the under-masculinized young man, a former soldier, who walked into their clinic one day.

But they and the soldier didn’t know that they were beginning a years-long medical journey that would lead the researchers to discover a new genetic mutation, bolster the case for a counterintuitive medical treatment, and push the limits of male fertility.

Dr. Karen Tordjman, a senior lecturer at Tel Aviv University’s Sackler Faculty of Medicine didn’t have an immediate diagnosis for the under-masculinized young man who walked into her office.

A 25-year-old university student who had served in an elite commando unit in the Israeli navy, he was handsome in a fashion-model kind of way – rail thin, with a smooth face and delicate, feminine features. Closer inspection revealed no body hair other than sparse patches in his armpits and groin. His genitals were small and heavily scarred.

The young man had reluctantly agreed to visit the medical clinic at the insistence of his girlfriend, who wanted an explanation for his condition. He couldn’t have known he was initiating a years-long medical journey that would lead Dr. Tordjman and a team of physicians to discover a new genetic mutation, bolster the case for a counterintuitive medical treatment, and push the limits of male fertility.

“We offered treatment not for his future reproductive capabilities but for his appearance,” says Dr. Tordjman. “We didn’t guarantee him anything, but we said we’d try.”

Her research, published in the journal Andrologia, will allow future genetic screening for the mutation.

Dr. Tordjman and her colleague Dr. Amnon Botchan, also a Sackler lecturer, began by obtaining the patient’s medical records. The records showed that two of his uncles had been diagnosed with androgen receptor insensitivity — a rare condition that results in the body under-responding to the androgen hormones that drive male sexual development. Usually caused by a mutation in the androgen receptor gene, the condition impairs the development of male genitalia in the womb and of secondary male sexual characteristics during puberty.

In cases of complete androgen insensitivity, no male sexual development takes place. The result is men who look like women on the outside but have testes rather than female genitalia inside their bodies. Such cases are often diagnosed only during puberty, when the individuals develop breasts and other female sexual characteristics but do not start menstruating.

Dr. Tordjman’s patient, who reported a consistent heterosexual orientation, had not had sex reassignment surgery or been given androgen treatments to try to enhance his sexual development at birth. But he had been diagnosed with the same condition as his uncles and undergone operations to correct genital malformations at age three and to remove breast tissue during puberty. Genetic testing, performed with the help of French researchers Dr. Serge Lumbroso and Prof. Charles Sultan, confirmed that he had a mutation of his androgen receptor gene — one that had not previously been reported.

Hoping to masculinize the patient per his wishes, Dr. Tordjman started him on high-dose testosterone therapy. Theoretically, this type of therapy makes little sense for patients with androgen receptor insensitivity, because their bodies create plenty of testosterone — it’s just that they are unable to put it to use. But Tordjman had read about a case in which the therapy had worked and decided to give it a try.

After several months of weekly injections, the patient appeared dramatically more masculine. He gained 18 pounds — mostly of muscle — and grew hair on his face and body, leading him to shave for the first time in his life. His voice, which had always been high-pitched, did not change. The voice, says Tordjman, is stubbornly resistant to hormone therapy.

The treatments continued for four years, during which the patient and his girlfriend got married and eventually began talking about having a baby.

Infertility in men with androgen receptor insensitivity is nearly universal, even in mild cases; and no one with a case as severe as the patient’s was known to have successfully fathered a child. But having seen a significant improvement in his sperm count, Tordjman took another long shot and referred the couple for fertility treatment. When Tordjman next saw the patient several years later, he was pushing a baby girl into her office in a stroller.

Francois Englert, a Belgian Jewish professor at Tel Aviv University and a Holocaust survivor, shared the Nobel Prize in physics Tuesday, the third Jew in two days to win the esteemed award.

The prize for Englert and Peter Higgs of Britain for their discovery of the Higgs particle was announced by the Royal Swedish Academy of Sciences. The Higgs particle, known as the “God particle,” is said to have caused the Big Bang. Scientists confirmed the discovery of the Higgs particle, or Higgs boson, which Higgs first theorized in 1964, while working with the Large Hadron Collider in Geneva, Switzerland.

Englert, 80, has had “close research ties” with Tel Aviv University for 30 years, the university said. He is a Sackler professor by special appointment at its School of Physics and Astronomy.

On Monday,  Jewish Americans James Rothman of Yale University and Randy Schekman of the University of California, Berkeley, joined German-born researcher Thomas Suedhof of Stanford University in winning  the Nobel Prize in medicine.

An offer to advocate for Palestinian refugee rights to cooperate with advocates for the rights of Jewish refugees was rejected at the Zochrot conference. 

The conference went ahead on the supposed site of an Arab village on the Tel Aviv university campus on 29 and 30 September, despite attempts to have it cancelled.  Levana Zamir, the president of the Association of Jews from Egypt in Israel, who made the offer to cooperate,  watched the conference develop into a nightmare – a sick and calculated blueprint for the annihilation of Israel. (One can only marvel at the irony that the bastion of anti-Zionism that is Tel Aviv university, whose staff and students so enthusiastically participated in the conference, should cooperate in their own destruction. )

Here is Levana’s report:

Levana Zamir

This international conference initiated by the Israeli NGO Zokhrot (meaning ‘we remember’),  titled “Realizing the Return of Palestinian Refugees” took place over two days in the Eretz Israel Museum in Ramat Aviv – located on the site of the former Arab village of  Sheikh Mouniss.

It was  a nightmare to me.  Janet Dallal, an Israeli friend from Iraq, was there with me. The other heads of organisations of Jews from Arab countries decided not to come and speak out – saying it would give the conference too much  publicity. Now I can say they were wrong.

The aim of this conference was not to argue whether the Palestinian refugees have a right of return, but the realization of it,  termed ‘decolonization’ by the conference including in parts of north Tel Aviv where small Arab villages were located before 1948.

The conference got off to a slow start, talking about doing justice to the dispossessed and stateless Palestinian refugees, and with a few good words from Leila Hilal, Director of the Middle East Task force of the New America Foundation – the main organisation financing this conference, beside other European organisations.

Leila Hilal said she was embarrassed to open the conference knowing that ‘the right of return’ issue was very delicate for most of Israelis: I liked her opening very much. But she continued saying it was about time to do justice to those politically-displaced refugees and put an end to their suffering. From time to time she talked of “compensation”.

Professor  Dan Rabinovitz of Tel Aviv University (where else?) gave his presentation, saying that the ‘right of return’ would be granted to refugees born in Palestine and are still alive – not to their descendants – i.e. 200, 000 refugees.  A  ‘right of return’ given by Israel to Jews only is discrimination, he said. He asked for recognition and for an apology. The Return would not always be to the original locations, but to alternatives.

After three more presentations about “reconciliation”, the Serbian refugee model, and the research findings of an Arab doctoral student from the UK on displaced Palestinians, it was easy for me at the Q&A to say my few words over the microphone and to ask my question.  I said:
“I came here to give you a hand, to ask you to continue your fight to get back your properties and compensation because I am myself a refugee, a Jewish refugee from Egypt. We were dispossessed of all our family properties, of our identity, then expelled. There are a million Jewish refugees like me from Arab lands – Egypt, Iraq, Libya, Syria, Lebanon, etc.  So I propose to pool our efforts – Palestinian and Jewish refugees – to recover our properties, secure compensation, and not to accept the kizuz (cancelling out) proposed by Israel.

“My question to Leila Hilal was this: “as you represent the New America Foundation, dealing with refugees in the Middle East, would you agree to give us a hand, and deal with Jewish refugees too. Let’s do it together, hand in hand.”

Leila did not answer my question but asked the others to do so.  Prof. Dan Rabinovitz said that my request was absolutely right, but he was an expert on Palestinian refugees and dealt only with them. The doctoral student from the UK, Munir Nuseibah, said he would be ready to develop his research for both sides. But during the coffee break, when I asked him how he would like us to cooperate on his research, he said he could not cooperate. People around us heard his answer very clearly.

When Leila asked the Serbian expert to answer to another question about the success of the ‘right of return’ imposed on Serbia, she said that it was a very bad experience involving killing people, and it had to be stopped.

During the coffe break, the president and founder of Zokhrot, Eitan Bronstein (an Israeli), came to me and said he was ready to see how Zokhrot could cooperate with us to include the Jewish refugees in their themes and activities. At that moment I was really glad to be there, but Leila avoided me and disappeared. I will send her a short message.

Janet Dallal intervened during the afternoon sessions, reminding the audience (all of them leftists) of the existence of the second group of refugees, the Jewish Refugees from Arab Countries, and the role of the Arab League in all this.

The second and last part of the conference became a nightmare.

During the whole next day, the lecturers demonstrated what the Return would be like, geographically – through animated short clips – and practically.

For example, in North Tel Aviv, on Ibn-Gvirol Street and the corner of Arlozorof – a sophisticated Tel-Avivian neighbourhood where an Arab village called Soumayel was located – the ‘Israeli occupiers’ would have the right to decide to leave their homes or stay and pay the ‘Palestinian refugee owner’ the ‘market value’ of their house. Then the ‘Palestinian Refugee owner’ would decide between recovering ‘his’ house or taking the money, with all that entailed. The Israeli ‘occupiers’ could not pass their homes on as inheritance to their descendants, etc. etc.

The Palestinian refugee who did not wish to Return, would get all their rights as Israeli citizens (Bituah Leumi national insurance rights, etc). in the paradise of One state for Two Peoples.  There was never any talk of “two separate nation-states”.

Everything is already settled for the Return to Arab villages too. The speakers planned, for example, how the ‘new’ Arab village of Ladjoun, on the edge of the flourishing kibbutz Meggido in the North,  will look, and under which conditions two Arab buildings still located inside the kibbutz would be incorporated into the village.

All this seemed to me sick and destructive, so the second day I did  not attend the conference but watched via the On-line conference link on the Zokhrot Facebook page.

The conference continued in this vein. Some lecturers even said, “Zionism is a crime” and nobody objected, except one lady who said: ” please respect others’ beliefs”. That was the only moment when I wished I had been there to say that today the word “Zionism” has no meaning any more – because the State of Israel belongs to the people of Israel. We are Am Israel, living in Medinat Israel.

To sum up, I cannot believe this is happening to us, that Israelis could side with our enemies so as to annihilate the State of Israel. This conference came one step closer towards this annihilation. I would like to say to all those who were there, that the creation of the State of Israel after 2,000 years was a miracle, and that the people of Israel on its own land is neither invincible, nor should it be taken for granted.

Tel Aviv University and China’s Tsinghua University have signed a Memorandum of Understanding for strategic cooperation in innovative research and teaching, with an investment of hundreds of millions of dollars.

A new research center in China initially will focus on life sciences and nanotechnology but later will include other sciences and high-tech, Globes reported.

The new “XIN” center will recruit researches and students in Israel and China.

Tel Aviv University president Prof. Joseph Klafter said that founding the new center is a sign of how much China looks to Israel for innovation.

Cinnamon, once thought to have been carried on trade routes in ancient Israel, may have been made along the northern Israeli coast and not just in Africa and India, as previously thought, Israeli researchers told LiveScience.

They analyzed 27 flasks from archaeological sites in Israel dating back 3,000 years and found that the compound that gives cinnamon its flavor was in 10 of the containers.

Cinnamon bark is found in southern India, and another form of the spice is found in China and southeast Asia. It is now yet known the source of the cinnamon in the flasks found in Israel, but the discovery that it probably was made in Israel “raises the intriguing possibility that long-range spice trade from the Far East westward may have taken place some 3,000 years ago,” the Tel Aviv University and Weizmann Institute researchers wrote in a paper to be published in the journal Mediterranean Archaeology and Archaeometry.

“We don’t think they sailed directly [to the Far East]; it was a very hard task even in the 16th century A.D.” Dvory Namdar, a researcher with the Weizmann Institute of Science and Tel Aviv University, told LiveScience in an interview.

Namdar and research colleague Ayelet Gilboa of the University of Haifa said the flasks, which at that time were in area that was part of ancient Phoenicia, feature a narrow opening with thick walls, indicating their contents were highly prized. Flasks with similar shapes previously have been found in temple storerooms and treasuries of ancient kingdoms, the researches added.

They think that the cinnamon bark was brought from the Far East to ancient Israel and mixed with liquids before it was placed in the flasks prior to shipping the spice elsewhere.

Namdar and Gilboa speculate that people of the time mixed the cinnamon in with wine. “If you mix it with a bigger [container of wine], then you get flavored wine,” they said.

These lone soldiers, hailing from countries including the United States, Canada, Great Britain, Turkey and Azerbaijan arrived in Israel without their families to join the Israel Defense Force and help build the Jewish nation.  ’Garin’ means seed in Hebrew but can also refer to a group of people who collectively immigrated to Israel and ‘tzabar’ refers to the ‘sabra’ cactus fruit which is prickly on the outside but soft and sweet on the inside, a euphemism to describe Israelis.

The Garin Tzabar program is in charge of bringing these lone soldiers to a kibbutz or Israeli city, providing them with an adopted family, a Garin community that supports them throughout their army service and Hebrew classes to assist their immersion into the IDF.  Several months from now the new recruits will begin to serve in the Israeli Army.  The Garin Tzabar  ensures lone soldiers receive support and attention on their birthdays, during holidays, Shabbat, and their days off .

The State of Israel officially welcomed this year’s Garin Tzabar participants during a special ceremony held at Tel Aviv University. Prime Minister Benjamin Netanyahu  gave a video greeting praising these young Jewish men and women and  numerous other government officials attended the event.

MK Sofa Landver, who addressed the group, stated, “We are here to receive the immigrants and the soldiers in our country, the most wonderful country in the world. It’s you who have come to serve and defend Israel. You will change the world.” A representative of Nefesh B’Nefesh added, “It’s not just a plane ride, it’s the destination and that’s Israel. Enjoy your new life.”

Netta Gelb, a new Garin Tzabar participant, was born in the Israeli city of Netanya and has spent the past 15 years growing up in Canada. Although she has Israeli relatives,  she is leaving behind her parents and siblings.  Gelb expressed the excitement many Garin members felt when she said, “I have been really looking forward to this for a long time.”

Michael Kosky, another Garin Tzabar participant, added, “We have come here to play our chapter in Jewish history. I am part of this program. Good luck to every one here.”  A lone soldier already serving in the IDF named Ariella, who hails from an Argentine family and grew up in both America and Israel told the audience that she holds dear the “values of loyalty to the state, its people, and the Tzabar members” and said to the new recruits “If you live together, you will learn a lot.”
