Italian lawmakers on Wednesday gave their final approval to a law that allows limited use of a controversial type of stem cell therapy which has been condemned by many scientists but has given hope to families of terminally-ill children. The law gives the go-ahead for therapy being carried out by...
The 2012 Nobel Prize in Medicine was awarded to Shinya Yamanaka and John Gurdon for the discovery that differentiated cells in the body can be reprogrammed. This finding led to the development of “induced pluripotent stem cells.” These cells were once skin or blood cells. Through a process of artificial reprogramming in the lab, scientists [...]
To celebrate the 60th anniversary of the discovery of the structure of DNA, King's will sponsor an annual 'King's College London Rosalind Franklin Lecture' at the Hay Festival of Literature, as part of its public engagement programme.
Although it seems that investors have lost their appetite for many stem cell investments at this stage of the broader rally in the stock market, there are exceptions worth pointing out. Neuralstem (NASDAQ: CUR ), for instance, has been in a strong uptrend since, on April 17th, the company finally received approval from the FDA to commence a Phase II clinical trial in 18 patients with ALS (amyotrophic lateral sclerosis) using its line of spinal-cord derived stem cells NSI-566. These proprietary stem cells can be differentiated into neurons, which can (in theory) replace the dying cells in a patient with a neurodegenerative disease...
Millions of years of evolution have molded our eyes into highly sensitive optical detectors, surpassing even many man-made devices. Now, Leonid Krivitsky and his co-workers at the A*STAR Data Storage Institute and the A*STAR Institute of Medical Biology, Singapore, have shown that the photoreceptor cells found in the retina are even sensitive to the statistical properties of light. This ability could be harnessed in 'bioquantum' interfaces, a novel class of optical devices that use biological systems to detect the quantum nature of light...
When studying any kind of population—people or cells—averaging is a useful, if flawed, form of measurement. According to the US Census Bureau, the average American household size in 2010 was 2.59. Of course, there are no homes with exactly 2.59 people. By inspecting each house individually, one would see some homes occupied by a single individual, and others by large families. These extremes get lost when values are averaged over a population.
