Revealing particle separation
Traces of biomolecules such as DNA can be detected with a new 'dynamic' technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly bind two nanoparticles together. This can be detected in real time through a change in light scattering. As reported in the journal Angewandte Chemie, this method differentiates true signals from noise and can detect deviations of individual bases. (2017-07-18)

New gel coatings may lead to better catheters and condoms
Catheters, intravenous lines, and other types of surgical tubing are a medical necessity for managing a wide range of diseases. But a patient's experience with such devices is rarely a comfortable one. MIT engineers have designed a gel-like material that can be coated onto standard plastic or rubber devices, providing a softer, more slippery exterior that can significantly ease a patient's discomfort. The coating can even be tailored to monitor and treat signs of infection. (2017-07-18)

Tiny particles increase in air with ethanol-to-gasoline switch
The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to a new study by a Northwestern University chemist, a National University of Singapore economist and two University of São Paulo physicists. The research team also found when drivers switched back to ethanol because prices had gone down, the concentration of ultrafine particles also went down. (2017-07-17)

Ozone pollution connected to cardiovascular health
Exposure to ozone, a risk for impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. A JAMA Internal Medicine study followed 89 healthy adults living in Changsha City for one year. They showed blood platelet activation and an increase in blood pressure, suggesting a possible mechanism by which ozone may affect cardiovascular health. (2017-07-17)

MPFI scientists probe function of cerebellar interneurons with new technique
Researchers at the Max Planck Florida Institute for Neuroscience developed a technique for selectively targeting and controlling the interneurons of the cerebellar molecular layer relying on a genetically engineered mouse model that exploits a unique gene encoding c-Kit to differentiate interneurons from other cell types. By using the c-kit mice in this study, the team was able to specifically access molecular layer interneurons and manipulate their activity using both optogenetic and chemogenetic methods in vitro.

Thinking thin brings new layering and thermal abilities to the semiconductor industry
The concept of a simple technique to remove thin layers from otherwise thick, rigid semiconductor crystals has been actively explored for years. In a significant advance, a research group from IBM successfully applied their new 'controlled spalling' layer transfer technique to gallium nitride (GaN) crystals, a prevalent semiconductor material, and created a pathway for producing many layers from a single substrate. They report their work in this week's Journal of Applied Physics. (2017-07-11)

A mouse's view of the world, seen through its whiskers
Neuroscientists have thoroughly mapped the touch, visual and auditory regions of the brain's cortex, but how does this sensory information get processed into our perception of the world? UC Berkeley researchers have for the first time reconstructed the spatial map a mouse creates with its whiskers, and found evidence that layers 2 and 3 of the somatosensory cortex integrate the discret inputs from each whisker to create a smooth map of the surrounding world.

Genes, ozone, and autism
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism. (2017-06-23)

Drip by drip
How do crystals grow? The answer given in current textbooks is: Layer by layer atoms or molecules settle on an existing crystal surface. The research team Physical Chemistry at the University of Konstanz has now observed a preliminary stage of this crystal growth in glutamic acid that contradicts this classical principal of growth. Not individual atoms settle on an existing crystal surface, but nano-drips that already contain building blocks for growth. (2017-06-21)

The Asian summer monsoon -- a smokestack to the Northern Hemisphere stratosphere
The formation of Asian tropopause aerosol layer is considered to be caused by the Asian summer monsoon, which effectively pumps the Asian pollutants to the upper troposphere and lower stratosphere, leading to enhanced aerosol formation. Chinese and American scientists used in situ measurements combined with modeling work to show that these particles subsequently spread throughout the entire Northern Hemispheric (NH) lower stratosphere, and contribute significantly (~15 percent) to the NH tratospheric column aerosol surface area on an annual basis. (2017-06-19)

MAVEN's top 10 discoveries at Mars
Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world. (2017-06-16)

New prospects for universal memory -- high speed of RAM and the capacity of flash
One of many research teams and companies' major goals is to develop universal memory -- a storage medium that would combine the high speed of RAM with nonvolatility of a flash drive. MIPT's researches turned to atomic layer deposition which enables unprecedented control over film thickness and coating of 3-D structures, which is problematic for most of the currently used nanofilm deposition techniques. To do this, the team worked with a unique experimental cluster form MIPT's Center of Shared Research Fcailities. (2017-06-16)

Hot rocks, not warm atmosphere, led to relatively recent water-carved valleys on Mars
Some scientists have interpreted water-carved valleys on Mars formed within the last few billion years as a sign of either an active groundwater system or of transient warm periods in the atmosphere. But new research shows that snow and ice melted by hot impact ejecta could have produced enough water to carve those valleys with no groundwater or heat wave required. (2017-06-13)

Granular material conductivity increases in mysterious ways under pressure
In a recent study published in EPJ E, a French team of physicists made systematic measurements of the electrical resistance -- which is inversely related to conductivity -- of metallic, oxidized granular materials in a single 1-D layer and in 3-D, under compression. Mathieu Creyssels from the Ecole Centrale of Lyons, Ecully, France, and colleagues show that the granular medium conducts electricity in a way that is dictated by the non-homogenous contacts between the grains.
