NEW YORK, July 15 (Xinhua) -- A Gallup survey released on Friday found a total of 59 percent of Americans support a ban on smoking in all public places.The July 7-10 survey among 1,016 national adults showed a change in the public's attitude toward public smoking ban. In 2001, when Gallup first asked about a ban on public smoking, 39 percent were in favor, an attitude that stayed roughly the same through 2007.At the same time, the poll also found that fewer than two in 10 people supported the idea of making smoking totally illegal.According to the American Lung Association, 27 states plus the District of Columbia have passed comprehensive smoke-free laws. A New York City law bans smoking in virtually all public places, including outdoor plazas and beaches.

SINGAPORE, Sept. 7 (Xinhua) -- Singapore scientists have found possible new ways to treat a type of aggressive breast cancer that is unresponsive to current forms of treatment, local broadcaster Channel NewsAsia reported on Wednesday.The team of scientists at the Genome Institute of Singapore ( GIS) and National University of Singapore (NUS), led by GIS senior group leader Qiang Yu, found that the enzyme EZH2 acts by inhibiting genes that stop the growth of tumors in the body.The insights could open the door to developing more effective treatment for fast spreading breast cancers, especially the estrogen receptor-negative breast cancer that is common all over the world.It was also found that through EZH2, cancer is promoted in the body by activating specific genes that impact breast cancer progression and cancer stem cell self-renewal.Yu said the new understanding on how EZH2 works as a cancer- causing gene in breast cancer has important therapeutic implication."The results suggest that small molecule drugs that block enzyme activity of EZH2 may not work for cancers caused by EZH2's activation genes," Yu said.Currently pharmaceutical companies have been developing drugs only to the block EZH2 enzyme activity so that tumor suppressers can perform their protective role in blocking cancer growth.Researchers said the next step would be to develop biomarkers to identify tumors with EZH2.This step would enable better treatment methods, with one of options being the development of therapies that shut down EZH2 completely and not just inhibit its enzymatic function.The findings have been published on the journal Molecular Cell.

MOSCOW, Aug. 26 (Xinhua) -- Russia will carry out two unmanned test launches of Soyuz carrier rockets in the coming fall before delivering crews to the International Space Station (ISS), local media reported on Friday.Citing a source, RIA Novosti news agency said that one of the Soyuz rockets was scheduled to send a new Progress M-13M space freighter to the ISS.On Wednesday, a Progress M-12M cargo ship failed to reach the orbit after the engine of a Soyuz-U carrier rocket turned off during the ascend. Soon after the accident, Russia announced it will temporarily ground all Soyuz rockets.Due to the accident, Russian space authorities have put off Thursday's launch of a Soyuz-2 carrier rocket from the Plesetsk Space Center in northern Russia and a launch of a manned space ship from Baikonur space center in Kazakhstan.After the retirement of the U.S. shuttle fleet, Russia's Soyuz spacecrafts have become the only way for astronauts to reach the ISS until at least the middle of the decade.

BEIJING, June 12 (Xinhua) -- China's Supreme People's Court (SPC) on Sunday publicized a judicial interpretation which sets specific rules for the country's courts to order penalties to criminals sabotaging TV and radio facilities.The interpretation said that criminals, whose sabotage causes information block for disaster early warning, rescue and others concern public security, could be convicted three to seven years of imprisonment on the charge of sabotaging TV and radio broadcast facilities.Other circumstances that could be convicted the imprisonment include sabotage that causes malfunction in the broadcast of TV and radio stations, according to the new law.According to statistics with the SPC, there have been more than 5,000 cases of sabotaging cable TV wires and more than 1,000 cases of sabotaging state-owned fiber optic lines and other cases of stealing broadcast facilities since 2006 in China.

BEIJING, Aug. 12 (Xinhuanet) -- A Connecticut woman who was savagely attacked by a pet chimpanzee and had her face deformed in 2009 was shown on TV with a new face Thursday.TV pictures revealed Charla Nash’s new nose, lips and eyelid, which were transplanted in May by doctors at the Brigham and Women’s Hospital in Boston.Nash said to the viewers that she can move her mouth, smile and smell. Her daughter Brianna added that her mother can even talk and eat better now.Dr. Bohdan Pomanhac led a 30-member surgical team to complete the face transplant in 20 hours. The team also transplanted two hands but these were later removed due to blood flow problem when Nash suffered pneumonia.Nash’s friend Sandra Herold owned a 15-year-old chimpanzee named Travis that attacked without any provocation when Nash was visiting Herold.Travis simply went berserk and could not be stopped even after Herold stabbed it with a kitchen knife. It would only let go of Nash after the police arrived and shot it dead.
