Cancer Breathalizer Comes out of Technion at Haifa

Wow. These Israeli inventions just keep coming, don’t they? We’ve heard of cancer sniffing dogs, so why not program some artificial intelligence to do the same thing? Revealed this week in Nature Nanotechnology journal, the “cancer breathalyzer” can detect lung cancer with 86 percent accuracy. It can even detect cancers that are not even large enough to show up on X-rays or CT scans. Detecting cancer that early could really save lives. The wonders of affordable technology!

HossamHow does it work? It tests for chemicals that are produced in cancer cells. They are ethylbenzene, decane, heptanol, and trimethylbenzne.

From what I remember from my organic chemistry days, these are all very flammable, but no, the detection does not involve attempting to set a patient’s breath on fire. There isn’t enough of it for that. Decane is a very long chain of hydrocarbons (ten carbons long actually) found in jet fuel, and heptanol is a 7-carbon chain with a hydroxide group at the end, making it an alcohol. Ha, college. The alcohol we drink, ethanol, is a 2-carbon alcohol. Don’t drink heptanol. It won’t make you any more drunk, but it will likely cause you, in drinkable amounts that is, to become dead.

The chemicals are detected using gold nanoparticles and an electric circuit. If the breath contains heptanol etc, the circuit goes off.

The research team was led by Hossam Haick, an Israeli Arab, pictured here, also the inventor of the electric nose.

Haick and his team have patented their device, but will continue to work to perfect it. The device must pass further clinical trials before being put to use. Good job Hossam!

Yosef “Tommy” Lapid dies at 77

Human Narration on

Tommy Lapid - Torch BearerFormer Minister of Justice, Yosef “Tommy” Lapid died this morning from cancer in Tel-Aviv. Lapid was a life-long journalist and publicist. He was a central figure in Israeli media, as is his son, Yair Lapid. In 1999, Tommy Lapid became chairman of Shinui, a political party which acted under the banner of secularism and the rights of the middle class.

Lapid was born in Serbia, and had survived the holocaust. Among his many positions, he served as the chairman of Yad Vashem, the holocaust memorial center. The word Lapid means “Torch” in Hebrew.

As a child, I became familiar with the name Lapid via the travel guides Tommy wrote in his travels around Europe. I remember his books being arranged on my parents’ cupboard. Later, I came to know him as the “loud man” on “Popolitica” — the weekly television panel, hosted by journalist Dan Margalit. Every week, Dan and the panel interviewed political guests and discussed current events, while accompanied by pop performances between the different items.

Later in his life, Lapid became the torchbearer of the secular vendetta. He led Shinui in 2003 when it gained its largest electorate ever, promising to fight religious coercion and to diminish the massive financial support that large parts of the orthodox community receive regularly from the government. As a result, he was accused of being overly divisive.

Whether you endorse Lapid’s doings or not, one thing is certain — his legacy is not one to be overlooked.

Safer Sex: Condoms Found to Block Cancer Causing Viruses

By Maurice Picow

It’s not just HIV/AIDS that people should be concerned about these days, when romantic interludes occur. A recent finding by an independent medical research organization, has found the regular use of condoms during sexual intercourse helps prevent the occurrence of cervical and other kinds of female genital cancers. The research findings concluded that use of these latex protection devices prevented vaginal warts and similar growths from forming as compared to test cases where partners had sex au natural. In fact those using condoms on a regular basis, female partners contracted these vaginal growths less than 50% of the time. The growths, found to be caused by certain viruses, were discouraged from forming due to condoms, proving that rubbers, though less enjoyable, are still one of the best bets for preventing disease, not to mention pregnancy.

The study, conducted among students at the University of Seattle, in the U.S. state of Washington, found that regular use of condoms during sex was even better than a use of recently introduced vaccine alleged to protect women against four different strains of human caused papillomavirus. Mr. James Allen, president of the American Social Health Association, said the “the findings are definite” in regards to the effectiveness of condoms.

Not only do condoms protect women against cancer, but for years now, their use has been proven to not only protect against fatal virus such as HIV/AIDS, but against other types of sexually transmitted diseases as well. Before the outset of AIDs in the early 1980s, use of condoms had already been proven to be invaluable for protection against a variety of diseases, including syphilis, gonorrhea, and others like herpes, a very common sexually transmitted disease which, though not fatal, can stay with those who contract it for life, flaring up from time to time, and making it’s victims literally miserable.

Young, sexually active couples, often think that using birth control pills is enough, if they only practice sex together and not with other individuals. This new study, participated in by female students between the ages of 18 and 22, has put new light in preventing female genital cancers, one of the most deadly cancers in women. While this new study is very reveling, it does contradict earlier studies made in which use of condoms during sex was inconclusive. Use of condoms while reducing the risks of contracting HIV/AIDS, does still not eliminate the possibilities of becoming infected, however, and the research panel still recommends that couples undergo full HIV/AIDs testing before become sexually active.

Israeli youth are at one of the worst risks, due to widespread non-use of condoms, although available virtually everywhere, and in an almost endless array of varieties, including many types that are designed to improve sexual enjoyment; and even some with flavors! And, as the prices for condoms have decreased proportionally in recent years, there’s simply no reason not to use them; except of course, selfish male “machoism”.

The next step, according to the panel, is to induce the U.S. Food and Drug Administration to require condoms sold in America to include warnings that non-use of condoms will increase risks of cancer in women. The bottom line: better be safe than sorry, even if it’s less fun!
