Gently rocking embryos while they grow during in vitro fertilization (IVF) improves pregnancy rates in mice by 22 percent, new University of Michigan research shows. The procedure could one day lead to significantly higher IVF success rates in humans. Researchers built a device that imitates the motion that embryos experience in the body as they make their way down a mammal's oviduct (a woman's Fallopian tube) to the uterus. Currently in IVF, eggs are fertilized with sperm and left to grow...

The development of a bionic eye that will restore vision to someone who is completely blind is a step closer after the research team working on the project detected signals in the brain from electrodes implanted in the retina of a living eye. The project, led by Associate Professor Michael Ibbotson from The Vision Centre and The Australian National University, has been investigating how artificial electrical signals can be converted into meaningful biological signals in the eye. It uses a...

The use and control of fire are behavioral characteristics that distinguish humans from other animals. Now, a new study by Iowa State University anthropologist Jill Pruetz reports that savanna chimpanzees in Senegal have a near human understanding of wildfires and change their behavior in anticipation of the fire's movement. An ISU associate professor of anthropology, Pruetz and Thomas LaDuke, an associate professor of biological sciences at East Stroudsburg (Pa.) University, co-authored the...

An overwhelming majority of people who have periodontal (gum) disease are also at high risk for diabetes and should be screened for diabetes, a New York University nursing-dental research team has found. The researchers also determined that half of those at risk had seen a dentist in the previous year, concluded that dentists should consider offering diabetes screenings in their offices, and described practical approaches to conducting diabetes screenings in dental offices. The study, led by...

In era of minimalist therapy, some mucinous carcinoma patients may need more, not less treatment In a large review of breast cancer patients with mucinous carcinoma, researchers at The University of Texas M. D. Anderson Cancer Center have identified an association between this rare type of breast cancer long-associated with a favorable prognosis and multiple tumors undetected by mammography or ultrasound. The study, presented today at the CTRC-AACR San Antonio Breast Cancer Symposium, is the...

A landmark, 25-year review of cases in which surgeons had to remove the lower portion of the body from the waist down for severe pelvic bone infections shows the therapy can add years and quality of life to survivors, say researchers at UT Southwestern Medical Center. The rarely performed surgery is called a hemicorporectomy or translumbar amputation, and involves removing the entire body below the waist, including legs, pelvic bone and urinary system. "It is used as a last resort on patients...

Magnetic resonance images (MRI) of patients diagnosed with multiple sclerosis in childhood show that pediatric onset multiple sclerosis is more aggressive, and causes more brain lesions, than MS diagnosed in adulthood, researchers at the University at Buffalo have reported. Interestingly, however, patients with pediatric-onset MS -- which comprise up to 5 percent of total MS cases -- develop disabilities at a slower pace than patients with adult-onset MS, the data showed. "Patients with...

A University of Adelaide study may have shed light on the rise in childhood asthma in developed countries like Australia in recent decades. Researchers from the University's Robinson Institute have identified a link between folic acid supplements taken in late pregnancy and allergic asthma in children aged between 3 and 5 years, suggesting that the timing of supplementation in pregnancy is important. Associate Professor Michael Davies says that folic acid supplements "“ recommended for...
