Live broadcast from inside the nerve cell

27-Jan-2015

Scientists estimate that our brain consists of about ten to one hundred billions of nerve cells. In order to fulfill their respective tasks as long as possible, these cells have to constantly control their internal proteins with regard to quality and functionality. Otherwise the proteins might ...

Nano-Beaker Offers Insight Into the Condensation of Atoms

23-Jan-2015

An international team of physicists has succeeded in mapping the condensation of individual atoms, or rather their transition from a gaseous state to another state, using a new method. Led by the Swiss Nanoscience Institute and the Department of Physics at the University of Basel, the team was ...

Shining a light on quantum dots measurement

20-Jan-2015

Due to their nanoscale dimensions and sensitivity to light, quantum dots are being used for a number of bioimaging applications including in vivo imaging of tumor cells, detection of biomolecules, and measurement of pH changes. When quantum dots are introduced in biological media, proteins ...

Gold nanoparticles show promise for early detection of heart attacks

20-Jan-2015

NYU Polytechnic School of Engineering professors have been collaborating with researchers from Peking University on a new test strip that is demonstrating great potential for the early detection of certain heart attacks.Kurt H. Becker, a professor in the Department of Applied Physics and the ...

Damaged DNA amplified

20-Jan-2015

In the majority of cases, the onset of cancer is characterised by a minor change in a person's genetic material. A cell's DNA mutates in a particular area to the extent that the cell no longer divides in a controlled manner, but begins to grow uncontrollably. In many cases, this type of genetic ...

The Number One of Enterobacteria Deciphered

Genome of the Escherichia coli type strain finally sequenced — DNA includes potentially pathogenic segments

19-Jan-2015

The colon bacillus Escherichia coli is one of the best studied model organisms in the life sciences. However, the reference organism for this species, its so-called type strain, has been overlooked in microbial genomics until now. In the “Genomic Encyclopedia of Bacteria and Archaea” (GEBA) ...

Tattoo-like sensor can detect glucose levels without a painful finger prick

16-Jan-2015

Scientists have developed the first ultra-thin, flexible device that sticks to skin like a rub-on tattoo and can detect a person's glucose levels. The sensor, reported in a proof-of-concept study in the ACS journal Analytical Chemistry, has the potential to eliminate finger-pricking for many ...

Graphene plasmons go ballistic

Graphene combined with the insulting power of boron nitride enables light control in tiny circuits with dramatically reduced energy loss

14-Jan-2015

Squeezing light into tiny circuits and controlling its flow electrically is a holy grail that has become a realistic scenario thanks to the discovery of graphene. This tantalizing achievement is realized by exploiting so-called plasmons, in which electrons and light move together as one coherent ...

Compact batteries enhanced by spontaneous silver matrix formations

Scientists use x-rays to map internal atomic transformations and advance promising lithium-based batteries

12-Jan-2015

In a promising lithium-based battery, the formation of a highly conductive silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries - and enhance the flow of electricity - scientists needed a way to see where, when, and how these ...

New Molecular Diagnostic Methods Could Reduce Risk of Miscarriage in Prenatal Testing for Genetic Diseases

09-Jan-2015

Early diagnosis and treatment are crucial to improving patient prognosis for 22q11 deletion syndrome and Wilson’s disease, two potentially life-threatening genetic conditions. Breaking research in Clinical Chemistry, the journal of AACC, shows for the first time that a more precise technology for ...
