Chemists make playdough/Lego-like hybrid to create tiny building blocks
Playdough and Legos are among the most popular childhood building blocks. But what could you use if you wanted to create something really small -- a structure less than the width of a human hair? It turns out, a team of chemists has found, this can be achieved by creating particles that have both playdough and Lego traits.

Sound waves separate biological nanoparticles for 'liquid biopsies'
A prototype device developed by an international team of engineers can sift exceedingly tiny particles called exosomes from blood samples without having to send samples off to a lab. The device, which combines acoustic cell-sorting and microfluidic technologies, could be a boon to both scientific research and medical applications.

A new approach to high insulin levels
Diabetes is characterised by a deficiency of insulin. The opposite is the case in congenital hyperinsulinism: patients produce the hormone in excessive quantities. This leads to chronic hypoglycaemia. The disorder can lead to serious brain damage and even death in the worst cases. A team at the University of Geneva (UNIGE), Switzerland, supported by the Swiss National Science Foundation has succeeded in describing the effects of a frequent genetic mutation in cases of congenital hyperinsulinism.

CCNY-led research team identifies new organelle in parasitic wasp venom
City College of New York biologist Shubha Govind and her research team have identified the composition of 'virus-like particles' (VLPs) found in the venom of a wasp that is a parasite of fruit flies. Invisible to the eye, wasp VLPs suppress the flies' immune responses by killing their blood cells.

Sustainable recreational fisheries the focus of $1.5 million NSF grant
With support from a $1.5 million National Science Foundation grant, Christopher Solomon, an aquatic ecologist at the Cary Institute of Ecosystem Studies, is co-leading a study assessing links among people, lakes, and fish in the Northern Highland Lake District in Wisconsin, a region where fishing holds tremendous value economically, socially, and culturally.

Couples weather bickering with a little help from their friends
New research finds that having good friends and family members to turn to alleviates the stress of everyday conflict between marital partners. According to a new study led by The University of Texas at Austin's Lisa Neff, social networks may help provide protection against health problems brought about by ordinary tension between spouses.

New Orleans greenery post-Katrina reflects social demographics more than hurricane impact
Popular portrayals of "nature reclaiming civilization" in flood-damaged New Orleans neighborhoods romanticize an urban ecology shaped by policy-driven socioecological disparities in redevelopment investment, ecologists argue in a new paper in ESA's open access journal Ecosphere. Studying plant life across the city, they found that demographic factors of wealth, race, housing recovery, and land abandonment were better predictors of vegetation patterns than the degree of intensity of flooding and wind during 2005's Hurricane Katrina.

New analysis shows damage to monarch butterfly colonies in 2016 storm worse than thought
A much greater number of monarch butterflies perished in a snowstorm in March 2016 in Mexico than previously estimated, according to new research. Analysis of damage from the storm--and the ensuing salvage logging--sheds further light on the precarious state of the famed butterflies' overwintering colonies.

New insights into nanocrystal growth in liquid
PNNL researchers have measured the forces that cause certain crystals to assemble, revealing competing factors that researchers might be able to control. The work has a variety of implications in both discovery and applied science. In addition to providing insights into the formation of minerals and semiconductor nanomaterials, it might also help scientists understand soil as it expands and contracts through wetting and drying cycles.

$1.6M from NSF to UC Davis to study water, land use in disadvantaged communities
The National Science Foundation has awarded $1.6M to the University of California, Davis to analyze the complex relationships between surface water and groundwater supply, agricultural land use and the economic wellbeing of rural, disadvantaged communities. The project is led by principal investigator Helen Dahlke, an associate professor in the UC Davis Department of Land, Air and Water Resources. The team will develop models to help guide decision-making regarding water management and land use in the state.

Physicists offer explanation for diverse galaxy rotations
A University of California, Riverside-led team of physicists has found a simple and viable explanation for the diversity observed in galactic rotations. Hai-Bo Yu and colleagues report that diverse galactic-rotation curves, a graph of rotation speeds at different distances from the center, can be naturally explained if dark matter particles are assumed to strongly collide with one another in the inner halo, close to the galaxy's center -- a process called dark matter self-interaction.

People of color exposed to more pollution from cars, trucks, power plants over 10 years
A new nationwide study finds that the US made little progress from 2000 to 2010 in reducing relative disparities between people of color and whites in exposure to harmful air pollution emitted by cars, trucks and other combustion sources. It found disparities in NO2 exposure were larger by race and ethnicity than by income, age or education, and that those inequities persisted across the decade.

Plant geneticists develop a new application of CRISPR to break yield barriers in crops
Scientists at CSHL have harnessed the untapped power of genome editing to improve agricultural crops. In tomato they have mobilized CRISPR to rapidly generate variants of the plant displaying a continuum of three agriculturally important traits: fruit size, branching architecture and overall plant shape. All are major components in determining yield. The method is designed to work in all food, feed, and fuel crops, including staples rice, maize, sorghum and wheat.

'The dark side' of quantum computers
The era of fully fledged quantum computers threatens to destroy internet security as we know it. Researchers are in a race against time to prepare new cryptographic techniques before the arrival of quantum computers, as cryptographers Tanja Lange (Eindhoven University of Technology, the Netherlands) and Daniel J. Bernstein (University of Illinois at Chicago, USA) describe today in the journal Nature. In their publication they analyze the options available for this so-called post-quantum cryptography.
