A drug used for the treatment of sickle cell anemia in adults has now been shown to cause significant improvements in very young children with the disorder. The finding is an important one as these young patients are especially vulnerable to serious organ failure and even death at an early age. The study results will be published in the October 1, 2005, issue of Blood, the official journal of the American Society of Hematology.
Sickle cell anemia is a genetic blood disorder that can cause severe pain, fatigue, and organ damage to the kidneys, spleen, and liver. It occurs in about one in every 500 African-Americans. In the new study, 21 children from two to four years old who had sickle cell anemia were given the drug hydroxyurea orally as a flavored liquid formula. A majority of the children took the drug for at least four years and more than half of the participants completed all six years of the study.
The treatment was well-tolerated in the patients, with only one childs dosage permanently reduced during the study due to adverse effects. The drugs primary function, to counteract the effects of the disease by increasing and sustaining fetal hemoglobin production, was achieved in all study participants. Patients treated with hydroxyurea also weighed more and were taller than untreated children with the disorder – their growth rates were even comparable to those of normal children.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
