Who is happy?

Who is happy?
Psychology experts have been fond of stating in recent years that human happiness, or what psychology experts call subjective well-being, is largely independent of our life circumstances. The wealthy arent much happier than the middle class, married people arent much happier than single people, healthy people arent much happier than sick people, and so on. One might reasonably conclude, therefore, that changes in life circumstances would not........Go to the Psychology news blog (Added on 3/6/2007 4:57:05 AM)

Measles Virus To Kill Multiple Myeloma

Measles Virus To Kill Multiple Myeloma
Mayo Clinic Cancer Center has opened a new Phase I clinical trial testing an engineered measles virus against multiple myeloma, a cancer of the bone marrow that currently has no cure. This is the third of a series of molecular medicine studies in patients testing the potential of measles to kill cancer. This is the beginning of a long but exciting process, says Angela Dispenzieri, M.D., hematologist and lead researcher on the multiple........Go to the Infectious disease blog (Added on 3/6/2007 4:33:57 AM)

Natural antibiotics yield secrets

Natural antibiotics yield secrets
Frog skin and human lungs hold secrets to developing new antibiotics, and a technique called solid-state NMR spectroscopy is a key to unlocking those secrets. That's the view of University of Michigan researcher Ayyalusamy Ramamoorthy, who will discuss his group's progress toward that goal March 3 at the annual meeting of the Biophysical Society in Baltimore, Md.

Childhood obesity may contribute to earlier puberty

Childhood obesity may contribute to earlier puberty
Increasing rates of childhood obesity and overweight in the United States may be contributing to an earlier onset of puberty in girls, say scientists at the University of Michigan C.S. Mott Children's Hospital. In a new study reported in the recent issue of the journal Pediatrics, the scientists reveal that a higher body mass index (BMI) score in girls as young as age 3, and large increases in BMI between 3 years of age and first grade are........Go to the Weight watcher's blog (Added on 3/5/2007 5:05:10 AM)

MMR, chicken pox vaccines work for preemies

MMR, chicken pox vaccines work for preemies
Vaccines for measles-mumps-rubella and varicella, or chicken pox, are effective in extremely preterm infants, even though preemies' immune systems are not as developed as full-term babies. This confirms a long-held assumption by pediatricians and neonatologists across the country. "The assumption has always been that it would be OK, that very early babies would have enough immunity, but no one had formally researched the subject," said Carl........Go to the Pediatric news blog (Added on 3/5/2007 4:59:25 AM)

A key to male fertility

A key to male fertility
Until now, mutations of the LH hormone receptor were the only explanation known for sexual precocity in boys.

A new study being published by the American Physiological Society (www.The-APS.org) finds that the body responds differently to colitis (inflammation of the colon) based on whether the disease is acute (sharp and brief) or chronic (long-term). Researchers, using an experimental mouse model of colitis, discovered that the effects of acute colitis were linked to decreased body weight, food intake, and body fat content.

Every day for 10 years, a seemingly heart-healthy 53-year-old woman experienced rapid and irregular heartbeats. She had no personal or family history of high blood pressure or hyperthyroidism. She did not suffer from myocardial or coronary artery disease, or any abnormalities of the heart as best doctors and medical science could determine. Yet, she complained of heart palpitations and dizziness nearly to the point of fainting.

Opening And Closing The Genome

Opening And Closing The Genome
At any given time, most of the roughly 30,000 genes that constitute the human genome are inactive, or repressed, closed to the cellular machinery that transcribes genes into the proteins of the body. In an average cell, only about one in ten genes is active, or expressed, at any given moment, with its DNA open to the cell' transcriptional machinery.
