Quantum sensor's advantages survive entanglement breakdown: Preserving the fragile quantum property known as entanglement isn't necessary to reap benefits
Massachusetts Institute of Technology March 9th, 2015 The extraordinary promise of quantum information processing -- solving problems that classical computers can't, perfectly secure communication -- depends on a phenomenon called "entanglement," in which the physical states of different quantum particles become interrelated. But entanglement is very fragile, and the difficulty of preserving it is a major obstacle to developing practical quantum information systems.

Tiny nanoparticles could make big impact for patients in need of cornea transplant: Animal study shows that a nanoparticle applied at the time of surgery slowly releases needed medicine to reduce risk of rejection after eye surgery
Johns Hopkins Medicine March 9th, 2015 Fast Facts: Medicine-loaded nanoparticles show promise for humans needing corneal transplants. Tiny nanoparticles may be solution for medicine compliance. Animal study gives patients, family members and clinicians hope for more easily managing medicine after eye surgery. There are about 48,000 corneal transplants done each year in the U.S., compared to approximately 16,000 kidney transplants and 2,100 heart transplants [1] [2]. Out of the 48,000 corneal transplants done, 10 percent of them end up in rejection, largely due to poor medication compliance. This costs the health care system and puts undue strain on clinicians, patients and their families.

The chameleon reorganizes its nanocrystals to change colors
University of Geneva March 10th, 2015 Many chameleons have the remarkable ability to exhibit complex and rapid color changes during social interactions. A collaboration of scientists within the Sections of Biology and Physics of the Faculty of Science from the University of Geneva (UNIGE), Switzerland, unveils the mechanisms that regulate this phenomenon. In a study published in Nature Communications, the team led by professors Michel Milinkovitch and Dirk van der Marel demonstrates that the changes take place via the active tuning of a lattice of nanocrystals present in a superficial layer of dermal cells called iridophores. The researchers also reveal the existence of a deeper population of iridophores with larger and less ordered crystals that reflect the infrared light. The organisation of iridophores into two superimposed layers constitutes an evolutionary novelty and it allows the chameleons to rapidly shift between efficient camouflage and spectacular display, while providing passive thermal protection.

Is US immigration policy 'STEMming' innovation? Study sheds light on why foreign STEM students stay in US or return home
University of California - Santa Barbara March 11th, 2015 Foreign born graduate students in STEM (science, technology, engineering and math) disciplines who wish to pursue a career in industry or NGOs are much more likely to stay in the U.S. than those who wish to pursue a career in academia or government concludes a study by researchers at UC Santa Barbara's Center for Nanotechnology in Society. Published on March 11, 2015 in the open access journal PLOS ONE, the study provides new insight into why foreign-born graduate students in STEM fields choose to remain in the United States or return to their home countries after graduation. These students make up one third of the entire student population in STEM fields, and therefore play a crucial role in U.S. economic competitiveness.

Super-resolution microscopes reveal the link between genome packaging and cell pluripotency: A study using super-resolution microscopy reveals that our genome is not regularly packaged and links these packaging differences to stem cell state
ICFO-The Institute of Photonic Sciences March 12th, 2015 In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. Techniques, such as electron microscopy, allowed scientists to identify nucleosomes, the first and most basic level of chromosome organisation. Until now it was known that our DNA is packaged by regular repeating units of those nucleosomes throughout the genome giving rise to chromatin. However, due to the lack of suitable techniques and instruments, the chromatin organisation inside a cell nucleus could not be observed in a non-invasive way with the sufficient resolution. Now, for the first time, a group of scientists at the CRG and ICFO in Barcelona, have been able to visualise and even count the smallest units which, packaged together, form our genome. This study was possible thanks to the use of super-resolution microscopy, a new cutting-edge optical technique that received the Nobel Prize in Chemistry in 2014. In combination with innovative quantitative approaches and numerical simulations, they were also able to define the genome architecture at the nano-scale. Most importantly, they found that the nucleosomes are assembled in irregular groups across the chromatin and nucleosome-free-DNA regions separate these groups.
A study using Super-resolution microscopy reveals that our genome is not regularly packaged and links these packaging differences to stem cell state. A multidisciplinary approach allowed scientists to view and even count, for the first time, the smallest units for packaging our genome.
A joint patent has been filed by ICFO and CRG, who are now exploring business opportunities for marketing the classification and determination of the degree of pluripotency of stem cells before their use in cell therapy or research in biomedicine.
The work, published in Cell, is a successful example of the importance on having multidisciplinary projects and collaborations. This study has brought together biologists and physicists from the Centre for Genomic Regulation (CRG) and the Institute of Photonic Sciences (ICFO), both in Barcelona, Spain.

Antibiotic nanoparticles attack respiratory infection and reduce drug side effects
European Lung Foundation March 12th, 2015 Treating respiratory disease is often difficult because drugs have to cross biological barriers such as respiratory tissue and mucosa, and must therefore be given in large quantities in order for an effective amount to reach the target. Now researchers from Germany, Brazil and France have shown that the use of nanoparticles to carry antibiotics across biological barriers can be effective in treating lung infections. Doing so allows better delivery of the drug to the site of infection, and hence prevents the development of antibiotic resistance which may be caused by too large and continued doses of antibiotic. Additionally, such a strategy might help to overcome the rapid metabolism and excretion of the antibiotic from the body, which happens when it is administered by traditional routes, either orally or intravenously.
