JERUSALEM, Oct. 24 (Xinhua) -- A recent study carried out by Israeli researchers showed that the experience of motherhood is caused by alterations in the brain functions that help mothers locate and communicate with their offspring, especially if they are in distress.Researchers at the Hebrew University of Jerusalem said the results provide insight into how neural changes in response to odors and sounds help maternal behaviors develop in mothers."We know that distinct brain changes are linked with motherhood, " Dr. Adi Mizrahi, who conducted the research, said, "but the impact of these changes on sensory processing and the emergence of maternal behaviors are largely unknown."Mizrahi and his colleagues examined whether the primary auditory cortex -- a region in the brain that is involved in the recognition of sounds -- might serve to process the responses to their offspring's specific smell and voice.The research proved that the olfactory and auditory senses of female mice with their pups were triggered immediately after they gave birth, with especially strong responses to cries of distress."These processes help to explain how changes in the cortex in the brain facilitate efficient detection of pups," Mizrahi said.

ZHENGZHOU, Oct. 21 (Xinhua) -- A leading Chinese producer for quick-frozen snacks Thursday apologized for the production and sale of bacteria-contaminated dumplings and said that a recall was underway.A spokeswoman from Zhengzhou Sinian Food Co., Ltd. said they had confirmed the contamination of staphylococcus aureus, or golden staph, in its quick-frozen seafood and pork-stuffed dumplings.The company had started the recall and destruction of the contaminated products, said Lin Xiaohong, a marketing executive of the company, adding that an investigation into the source of the contamination was underway.The statement came after authorities in Beijing announced they had detected golden staph from one batch of dumpling products by the Henan-based company.

BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.

MOSCOW, Oct. 3 (Xinhua) -- A Soyuz-2.1B rocket carried a Glonass-M navigation satellite into orbit early Monday after a two-day delay caused by high winds, a Russian Space Forces spokesman said."The launch of the booster rocket is as scheduled. The satellite Glonass-M was put into the orbit under control at 03:55 Moscow time (2355 GMT on Sunday)," said Colonel Alexei Zolotukhin.Zolotukhin told reporters that the rocket was launched at 0:15 Moscow time (2015 GMT, Sunday) from the Plesetsk Space Center in northern Russia.The Russian Space Forces said the launch was initially scheduled for Saturday but was postponed due to high winds.Glonass is the Russian equivalent of the U.S. Global Positioning System (GPS), which is designed for both military and civilian use. The system requires 24 operational and 2-3 reserve satellites in orbit to ensure global coverage.In December 2010, a malfunction of the booster resulted in a loss of three Glonass satellites.

MINSK, Oct. 11 (Xinhua) -- Chinese telecommunications firm Huawei on Tuesday showcased its latest solutions in mobile broadband at an exhibition in Belarus.Focusing on the possibilities of expanding the capacity of mobile operators' networks, the solutions propose to use fourth-generation network standards and introduce elements of intelligent network resources.The exhibition also presented the latest generation of radios, transportation equipment, and terminal solutions."Mobile traffic is constantly increasing, but profit is not growing so fast - about 20 to 30 percent," Xu Zhidong, general director of Bel Huawei Technologies, said during the opening ceremony of the exhibition."We need to provide more services. In addition, the market should be presented by more terminal devices. The decisions, which are displayed at the exposition, will not only increase the volume of Internet traffic, but also increase average profit per subscriber," he added.Lu Guicheng, China's ambassador to Belarus, said Huawei has seen a very successful development, including in the Belarussian market.Huawei, China's largest telecommunications company, which began investing in Belarus in 2003, signed an agreement with the Eastern European nation last month to set up a network technology training center in Belarus for telecommunications technology research and training.It also agreed last month to help more than 300 Belarussian companies with their information technology construction over the next four years.
