Shattered chromosome cures woman of immune disease Call it a scientific oddity—or a medical miracle. A girl who grew up with a serious genetic immune disease was apparently cured in her 30s by one of her chromosomes shattering into pieces and reassembling. Scientists traced the woman’s improvement to the removal of a harmful gene through this scrambling of DNA in one of her blood stem cells—a recently identified phenomenon that until now had only been linked to cancer. The woman, who lives in Cincinnati, Ohio, suffered from recurring bacterial infections as a child. Back then, doctors found that she had abnormally low levels of certain white blood cells needed to fight invading microbes. In 2003, researchers linked WHIM to a gene called CXCR4, which codes for a cell surface protein that immune cells use to recognize chemical messengers called chemokines. The woman was that first WHIM patient, now 59 years old. The NIH team began sleuthing.
Radioactive Decay Rates Another example is the element Uranium-238 which has 54 more neutrons than its protons (Atomic umber =92). This element gains stability by passing through various types of decays (19 steps-- also known as the Uranium series) and is converted into Pb-206 (atomic number 82).For further information about different types of decay that Uranium goes through, refer to Decay Pathways). Decay Rates Due to the smaller size of the nucleus compared to the atom and the enormity of electromagnetic forces, it is impossible to predict radioactive decay. The atomic nucleus which is in the center of the atom is buffered by surrounding electrons and external conditions. or mathematically speaking A=λN where A is the Total activity and is the number of decays per unit time of a radioactive sample. Decay Rate & Chemical Kinetics Since the decay rate is dependent upon the number of radioactive atoms, in terms of chemical kinetics, one can say that radioactive decay is a first order reaction process. dNdt=−λN with
IPB - ENSTBB | Ecole nationale sup de tech des biomolecules de Bordeaux Where Science And Art Collide This is a guest post by Susana Simões Pereira. Have you ever heard of using dance to study science, as, for instance, cells movements? Well, John Bohannon has. Actually, he recently presented his “Dance Your PhD” project at TEDxBrussels, which aims to use dance as a way to study and communicate science efficiently. But using art as a mean to communicate science to scientists and non-scientists, kids and adults, is the intent of some other interesting projects like “The love motel for Insects” at NYC. Another kind of SciArt project is developed by Luke Jerram. These are some of many examples that show learning science can be indeed fun and take place in very different contexts from the ones we’re used to. Susana Simões Pereira is a Portuguese mathematician and PhD student in Science Communication. [Note from Sheril: This is a phenomenal TED Talk - Click play!]
Research team edits the DNA of fertilized human embryos For several weeks, rumors have been circulating that a research group in China had performed the first targeted editing of DNA in human embryos. Today, the rumors were confirmed by the appearance of a paper in the journal Protein & Cell, describing genome editing performed at Sun Yat-sen University in Guangzhou, China. The paper shows that while the technique can work, it doesn't work very efficiently, suggesting there are a lot of hurdles between existing techniques and widespread genetic engineering of humanity. To avoid potential ethical issues, the researchers performed their experiments with embryos that had been fertilized by more than one sperm. The work relied on the CRISPR-Cas9 system. This has worked in a variety of systems, and the authors confirmed that it works with their gene of choice: the hemoglobin component β-globin. (A second targeting RNA led to some off-target work and wasn't used for other experiments.)

The paper titled "Unexpected stable stoichiometries of sodium chlorides,” documents his predictions about, and experiments in, compressing sodium chloride—rock salt—to form new compounds. “I think this work is the beginning of a revolution in chemistry,” Oganov says. This opens all kinds of possibilities. To Oganov, impossible didn’t mean something absolute.

Hunter Cole - Artist and Scientist New Evidence That Plants Get Their Energy Using Quantum Entanglement GEORGE DVORSKY | Io9 | Jan 13th 2014 Biophysicists theorize that plants tap into the eerie world of quantum entanglement during photosynthesis. But the evidence to date has been purely circumstantial. Now, scientists have discovered a feature of plants that cannot be explained by classical physics alone — but which quantum mechanics answers quite nicely. The fact that biological systems can exploit quantum effects is quite astounding. Good Vibrations But for this to work, plants require the capacity to work in harmony with the wild, wacky, and extremely small world of quantum phenomena. Previous inquiries suggested that this energy is transferred in a wave-like manner, but it was a process that could still be explained by classical physics. In Perfect Quantum Harmony In the new study, however, UCL researchers identified a specific feature in biological systems that can only be predicted by quantum physics. The vibrations in question are periodic motions of the atoms within a molecule.
