WELLINGTON, Oct. 26 (Xinhua) -- New Zealand's geothermal scientists will be collaborating with the world's leading geothermal researchers after the country joins an elite international group next month.New Zealand would be admitted to the International Partnership for Geothermal Technology (IPGT) in Melbourne, Australia, on Nov. 16, Science and Innovation Minister Wayne Mapp announced Wednesday."Geothermal energy is one of our most important renewable energy resources with huge potential for growth," said Mapp."This recognition of our geothermal research programs will allow our scientists to collaborate with an elite group of researchers in the United States, Australia, Switzerland and Iceland."Scientists from New Zealand research organizations were committed to finding new ways to harness the country's extensive geothermal fields, said Mapp."Innovation and clean energy is a big part of enabling New Zealand to grow the economy," said Mapp."This new international partnership will help keep us at the forefront of technology developments such as enhanced geothermal systems."Established in 2008, the IPGT seeks to develop advanced, cost- effective geothermal energy technologies through international research co-operation.New Zealand's geothermal electricity generation rose by 21 percent last year and accounted for 13 percent of total electricity generation, its highest recorded level.The government is aiming to expand geothermal energy with three large geothermal projects in the pipeline by 2020.The country's biggest geothermal project is to be Contact Energy's 250-megawatt Tauhara II geothermal project.The project, being developed northeast of the central North Island town of Taupo, is expected to produce enough electricity to meet the needs of around 270,000 homes when it becomes fully operational in 2015.

BEIJING, Nov. 20 (Xinhua) -- Chinese Vice Premier Li Keqiang visited HIV/AIDS medical personnel, volunteers of non-government organizations (NGOs), and people living with HIV ahead of the World AIDS Day which falls on Dec. 1.In the voluntary testing clinic of the Beijing Diseases Prevention and Control Center (CDC), Li said counseling and testing are crucial to the early detection and early treatment of HIV/AIDS, and encouraged the clinic staff to work hard on the very front-line of HIV prevention and control.While visiting NGOs situated in the Beijing CDC, Li greeted people living with HIV and volunteers, shaking hands with them. He recognized the role of NGOs in keeping the disease at bay, particularly in terms of HIV/ AIDS awareness education and intervention.Chinese Vice Premier Li Keqiang (C) talks with a HIV/AIDS medical personnel as he visits the voluntary testing clinic of the Beijing Diseases Prevention and Control Center (CDC), in Beijing, China, Nov. 18, 2011.Li said HIV prevention and control is a systemic project that takes the entire society to carry out, calling for establishing a mechanism to involve "social forces" into HIV prevention and control.Li asked health authorities at all levels to keep close contact with HIV-related NGOs, providing assistance needed to these organizations and their volunteers."Care, respect and assistance are the best pain relievers for people living with HIV," Li said, calling upon the entire society to pay greater attention and care to this group of people.

COPENHAGEN, Oct. 1 (Xinhua) -- Denmark implemented a tax on foods high in saturated fat from Saturday, the first of its kind in the world, which will affect products containing more than 2.3 percent saturated fat.Butter, cream, cheese, meat, cooking oil and processed foods like pizza and dark chocolate are among thousands of products affected. The so-called fat tax is pegged at 16 Danish kroner (2.87 U.S. dollars) per kilo of saturated fat.Thus, a 250-gram packet of butter, which previously cost 15.5 Danish kroner (2.78 dollars), will now cost 18.10 Danish kroner (3.25 dollars). And the cost of a liter of olive oil has risen from 38.95 Danish kroner (7 dollars) to 41.60 Danish kroner (7.48 dollars), for example.Some Danes began hoarding the affected products ahead of Saturday's deadline, while stores across Denmark rushed to mark-up prices of these goods.Although the new tax will mean higher costs for consumers and many food product manufacturers, the Danish government believes the tax is a good way of reducing Danes'consumption of fatty foods.Local producers are worried the tax will give an unfair advantage to manufacturers from neighboring countries who, they say, can now sell their products more cheaply in the Danish market.However, tax authorities here said imported food products will also be subject to the tax.

BEIJING, Oct. 11 (Xinhuanet) -- For women, chocolate consumption needs to be high, which can lower stroke risk, researchers from the Karolinska Institute, Sweden, reported in the Journal of the American College of Cardiology. The consumption of chocolate has been demonstrated to reduce diastolic and systolic blood pressure in randomized, short-term trials. Chocolate has also been shown to improve endothelial and platelet function, and to improve insulin resistance.Susanna Larsson Ph.D. and the team conducted the research on the Swedish Mammography Cohort's 33,372 adult females aged from 49 to 83 years without history of stroke, coronary heart disease, stroke, or diabetes.They found those who ate at least two chocolate bars each week appeared to have a 20 percent lower risk of stroke, compared to those of the same age and weight who rarely or never ate chocolate. But, they found, it was only those in the highest quartile of chocolate consumption who had a significant drop in stroke risk.The researchers explained that cocoa has flavonoids - powerful antioxidants that can suppress LDL, low-density lipoprotein, that can cause stroke and other cardiovascular diseases.

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.
