Childrens Rehabilitative Services (CRS) at St. Josephs Childrens Health Center in Phoenix is using a special ultrasound to identify the risk for stroke in children who have sickle cell disease. The transcranial Doppler (TCD) ultrasound measures blood flow in the arteries, identifying the narrowness of the artery and assessing stroke risk.
The TCD ultrasound, which is placed at the base of the patients skull, measures the blood flow in the arteries. The more rapid the blood flow, the narrower the artery is, increasing the chance of developing a blood clot, which can eventually lead to a stroke.
The risk for stroke in people with sickle cell disease is greatest between the ages of two and 20 when the developing blood vessels are most susceptible to form plaques. Patients who are identified as high-risk for a stroke receive blood transfusions every three to four weeks to reduce their risk. Proper treatment can reduce the risk for stroke by approximately 90 percent.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...

In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
