BEIJING, Nov. 9 (Xinhuanet) -- Kids with a depressed father tend to have more behavior issues than those with a happy father, a latest US study shows.The study, published in the journal Pediatrics, used data from home interviews with almost 22,000 families. All of them had a child aged between five and 17, and both a mother and father living at home, according to a Reuters report Tuesday.After analyzing the data, researchers found 11 percent of the children with a depressed father had problems at home or at school, whereas only six percent of those with a happy father had such problems.This is one of the first large-scale studies focusing on the connection between depressed fathers and children's behavior, said study author Michael Weitzman from the New York University School of Medicine.In addition, the study echoed the previous finding that mothers' depression could increase children's emotional and behavior problems.It was reported that 19 percent of the children in the study struggled emotionally and behaviorally if their mother was depressed."Parents who are depressed tend to engage less with their children, tend to display less positive behaviors, and display more harsh, negative and critical behaviors," said Jeremy Pettit, a psychologist not involved in the study, cited by Reuters.

BEIJING, Sept. 30 (Xinhuanet) -- Miners, construction workers and people in hotel and food service industry are most likely to smoke in the U.S., according to new research finding.The finding was contained in a report released Thursday by the U.S. Centers for Disease Control and Prevention (CDC).According to the finding, miners and people in hotel and food service have a cigarette smoking rate of 30 percent, followed closely by construction workers' 29.7 percent.Both rates are much higher than the average smoking rate of 19.6 percent among all U.S. working adults.Workers in the education services industry have the lowest smoking rate, with 9.7 percent, followed by the 10.9 percent of workers in company management, the report said.Low education levels are a factor in high smoking rates, along with poverty and gender, said Ann Malarcher, senior scientific adviser at the CDC."Although some progress has been made in reducing smoking prevalence among working adults," the report wrote, "additional effective employer interventions need to be implemented."Smoking kills an estimated 443,000 each year in the U.S., costing about 193 billion U.S. dollars annually in direct health care expenses and productivity loss.

HAIFA, Israel, Oct. 5 (Xinhua) -- "It's a big day, a celebration shared by Israel, science and the entire world," Israeli researcher Daniel Shechtman, who won the 2011 Nobel Prize in chemistry, said here at a press conference at the Technion- Israel Institute of Technology.Shechtman, 70, has spent the past five decades at Technion. He is also an associate at the Ames Laboratory of the U.S. Department of Energy and has lectured at universities abroad."Thousands of scientists are currently researching the subject I developed and I'm sure that all of them view the prize as their accomplishment too," he told Xinhua, adding that, "Science (in general) wouldn't be here and be as prosperous and intricate as it is if not for the work of thousands of others around the world."The Swedish Royal Academy of Sciences on Wednesday announced Shechtman as the winner of this year's Nobel chemistry prize for his cutting-edge research on quasicrystals, a type of atom form that for decades was considered impossible by the global scientific community.The award panel explained that Shechtman's work, launched in early 1980s, has revolutionized the perception of solid matter.His work forced crstyallographers to revamp their basic conception that atoms inside crystals only have repeating and symmetrical patterns.Shechtman is the 10th Israeli scientist to win the Nobel Prize and the fourth to win the prize in chemistry.Ada Yonat, a researcher at the Weizmann Institute near Tel Aviv, received the chemistry prize in 2009.The announcement from Stockholm captured headlines in Israel, drawing praise from the country's leadership, who said Shechtman's achievement is a testament to the Jewish state's stature as a technological powerhouse.Israeli Prime Minister Benjamin Netanyahu said the winning of the Nobel Prize "expresses our people's intellect.""Every Israeli citizen is happy today and every Jew in the world is proud," a statement issued by Netanyahu's office quoted him as telling the scientist in a telephone call.Israeli President Shimon Peres, who is also a Nobel laureate, later called to congratulate Shechtman."You demonstrate that a thinking person who is hardworking and brave can make groundbreaking scientific discoveries," he said.

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.
