SAN FRANCISCO, Oct. 5 (Xinhua) -- Google announced Wednesday that Google Earth, the tech giant's virtual globe, map and geographical information program, has been downloaded more than one billion times since it was first introduced in 2005.According to Google's official blog, there have been more than one billion downloads of the Google Earth desktop client, mobile apps and the Google Earth plug-in. To celebrate the milestone, Google is aggregating all the interesting ways people have used Google Earth around the world and posting them on "www. OneWorldManyStories.com.""We never imagined our geospatial technology would be used by people in so many unexpected ways," said Google in the blog post.Google Earth maps the Earth by images obtained from satellite imagery, aerial photography and GIS (geographic information system) 3D globe. It also has versions of Moon, Mars and Sky, enabling users to see images and videos of the planets and distant galaxies.It is currently available in Google Earth, a free version with limited function, as well as Google Earth Pro and Google Earth Enterprise, subscription services with additional features intended for commercial use.

WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

VIENNA, Dec. 10 (Xinhua) -- China is one of the active supporters of the international community to European crisis settlement, Chinese Vice Foreign Minister Fu Ying said here on Saturday.Attending the fourth World Policy Conference, she voiced the hope that Europe could expand the mutually beneficial cooperation between Europe and China, and create a favorite condition for attracting investment from developing countries including China.In the afternoon, Fu attended a seminar with the topic of "Europe as a laboratory for global governance" and answered questions from the attendants.Asked if China and other BRICS countries should "rescue" Europe or not, she said that the word "rescue" often used by the European media could be misleading.She said that as the world's largest economy, the European Union (EU) has strong real economy and much higher living standard than developing countries. Europe does not need a "savior" but international partners with a win-win relationship.Currently, Europe is facing severe challenges such as the debt crisis and is actively seeking solutions. The EU is China's largest trading partner and one of the main sources of technology and investments. The settlement of crisis in Europe is closely related with not only the world but also China.China has been expressing its confidence in the European economy and the euro, believing that Europe is able to find out solutions to the problems, she said.She also pointed out that the current financial cooperation between Europe and China was mentioned in the same breath with the European financial expansion in Asia in the early 20th century by some European media, which was really a tale of a tub.China sticks to the foreign policy of promoting peace, development and cooperation, and has no intention to control European countries through financial tools, she said.Regarding to the role China played in the settlement of the current European debt crisis, Fu pointed out that China has been an active part of the international community supporting Europe to overcome its crisis.In addition to the cooperation in the financial sector, China also expands its imports, exploring ways to strengthen the investments in Europe and helping create jobs and restore economic growth, according to her.In her speech, she also said that in the process of industrialization, technological innovation, as well as in the fields such as green economy, Europe has always been a leading player in the world.After World War II, European countries learned from their mistakes and started the integration process to create lasting peace. The EU has been successful in maintaining regional peace and promoting economic prosperity. The governance experience in Europe is useful to other regions of the world.However, the European experience should not be completely copied by other regions due to their unique history and real situations.

JINAN, Oct. 24 (Xinhua) -- Chinese scientists have made a breakthrough that could lead to more effective treatments for leprosy.A team from Shandong Provincial Institute of Dermatology and Venereology in east China has identified two new risk variants near IL23R and RAB 32 genes that are responsible for the disease, according to a report published online Monday in the scientific journal Nature Genetics.Knowing that the two gene variants influence susceptibility to leprosy could allow doctors to diagnose the disease in sufferers earlier in its outset, as well as to develop new treatments. A genetic database could now be built up to predict those people particularly susceptible to leprosy, said Zhang Furen, the leader of the research team.The study involved more than 10,000 samples being taken from leprosy sufferers and healthy test subjects and analysed.Leprosy is a chronic nerve-killing disease that leads to problems with patients' skin, feet, hands, legs and eyes. More than 200,000 newly-contracted leprosy cases are reported worldwide every year, and China has around one tenth of the world's sufferers.
