Eliminating senescent cells could prevent or delay onset of age-related disorders

Researchers at Mayo Clinic have shown that eliminating cells that accumulate with age could prevent or delay the onset of age-related disorders and disabilities. The study, performed in mouse models, provides the first evidence that these "deadbeat" cells could contribute to aging and suggests a way to help people stay healthier as they age.

Regular physical activity associated with lower risk of depression in old age

Regular physical activity is associated with a lower risk of suffering depression in old age. This is shown by one of the largest studies on elderly Europeans to have been carried out, by researchers at the University of Gothenburg, Sweden, among others. Research also shows that self-determined motivation and perceived competence are important factors in persuading elderly people to exercise more.

China's 'one-child policy' delayed world's reaching population of 7 billion; China to maintain policy

"The world's population is expected to hit seven billion around October 31," CNN's Jaime FlorCruz reports in his column, "Jaime's China." This is a number that would have been reached five years earlier were it not for China's family planning policy, according to Zhai Zhenwu, a professor at Renmin University School of Sociology and Population. FlorCruz writes that experts at the National Population and Family Planning Commission of China say "the policy has prevented more than 400 million births in the country."

Scientists discover additional Alzheimer's proteins in the tangles

Scientists from the National Institutes of Health in the United States have made an important discovery that should forever change the scope and direction of Alzheimer's research. Specifically, they have discovered that the protein tangles which are a hallmark of the disease involve at least three different proteins rather than just one.

Adiponectin linked to osteoporosis and increased risk of fractures

While obesity is a well-known cause of cardiovascular disease, research from the Sahlgrenska Academy at the University of Gothenburg, Sweden, has now revealed that the body's obesity hormones - adiponectin - are also linked to osteoporosis and an increased risk of fractures.

Peroxiredoxin enzyme holds key to ageing process

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

Seven billion humans and counting

According to the United Nations Population Fund, the seven-billionth child is most likely to be a boy born in India or China, this week.

New top-down method can quickly separate, identify thousands of protein molecules

A team led by Northwestern University chemical biologist Neil Kelleher has developed a new "top-down" method that can separate and identify thousands of protein molecules quickly. Many have been skeptical that such an approach, where each protein is analyzed intact instead of in smaller parts, could be done on such a large scale.

Study: Many fetal expression changes are reversed immediately after birth

The "switching on" or expression of specific genes in the human genome is what makes each human tissue and each human being unique. A new study by researchers at the Johns Hopkins Bloomberg School of Public Health, the Lieber Institute for Brain Development, and the National Institute of Mental Health found that many gene expression changes that occur during fetal development are reversed immediately after birth.

Higher testosterone levels may reduce loss of lean muscle mass in older men

A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that higher levels of testosterone were associated with reduced loss of lean muscle mass in older men, especially in those who were losing weight. In these men, higher testosterone levels were also associated with less loss of lower body strength.
