Physicians and researchers at the UC Davis School of Medicine and Medical Center found that children with sickle cell disease who are exposed to tobacco smoke in the home have more complications from the disease than those who live in a smoke-free environment. The study was published in the December issue of the Archives of Pediatrics and Adolescent Medicine.
"Exposure to environmental or passive tobacco smoke increased the risk of sickle cell crisis by 90 percent, and was not influenced by other factors known to increase complications, such as age of the patient or type of sickle cell disease," said Daniel C. West, associate professor of pediatrics at UC Davis and lead author of the study. "Exposure to tobacco smoke has a tremendous impact on children with sickle cell disease. In fact, the study suggests that removing passive tobacco smoke from the home might not only reduce the suffering of children with sickle cell disease, but also reduce the cost of medical care."
Sickle cell disease is a hereditary disease that affects hemoglobin, the protein in red blood cells that carries and delivers oxygen to tissues. The presence of sickle hemoglobin can lead to damaged and misshapen red blood cells that do not flow normally through blood vessels and deliver less than the normal amount of oxygen to peripheral tissues. These abnormalities can cause episodes of severe pain, known as sickle cell crises, and life-threatening damage to vital organs, such as the lungs and the brain.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
