The successful transfusion of a cell-free blood product on a 14-year-old Jehovahs Witness may offer a solution for patients opposed to blood transfusions due to religious or personal beliefs.
"This was the first successful use of a human cell-free hemoglobin solution in a pediatric patient to manage life-threatening anemia due to an autoimmune disease," says Dr. Brian Kavanagh, professor of medicine at the University of Toronto and staff physician in critical care medicine at The Hospital for Sick Children. The patient suffered from immune thrombocytopenia, a condition that attacks platelets in the body. Platelets are present in blood and help blood clot; if platelet counts are very low, minor injuries or trauma can become very serious if the patient continues to bleed.
Kavanagh and colleagues Drs. Johann Hitzler and Natalie Anton treated the patient last year after she entered the hospitals emergency room for a nosebleed that did not stop. Instead of a blood transfusion, they used a biochemically manufactured solution that contains hemoglobin but does not contain red blood cells. The solution has been used in adults but never for a child in this kind of situation, Kavanagh says.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
