How to make stronger, 'greener' cement
Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half -- and the result would be a stronger, more durable material.

NASA-NOAA's Suomi NPP satellite sees Tropical Storm Kammuri coming together
When NASA-NOAA Suomi NPP satellite passed over Tropical Storm Kammuri the VIIRS instrument aboard took a visible picture of the storm that showed bands of thunderstorms wrapped around its center. The storm appears to be coming together as circulation improves and bands of thunderstorms have been wrapping into the low-level center of circulation.

Satellite catches an oval-shaped Tropical Storm Rachel
NOAA's GOES-West satellite spotted the eighteenth tropical depression of the Eastern Pacific grow into a tropical storm that was renamed Rachel today, Sept. 25, 2014. Wind shear is affecting the tropical storm, however, so it doesn't have a rounded appearance on satellite imagery.

Researchers engineer 'Cas9' animal models to study disease and inform drug discovery
Researchers from the Broad Institute and Massachusetts Institute of Technology have created a new mouse model to simplify application of the CRISPR-Cas9 system for in vivo genome editing experiments. The researchers successfully used the new 'Cas9 mouse' model to edit multiple genes in a variety of cell types, and to model lung adenocarcinoma, one of the most lethal human cancers. A paper describing this new model and its initial applications appears this week in Cell.

Looking for a spouse or a companion
The increasing popularity of social media, online dating sites, and mobile applications for meeting people and initiating relationships has made online dating an effective means of finding a future spouse. The intriguing results of a new study that extends this comparison of online/offline meeting venues to include non-marital relationships are reported in an article in Cyberpsychology, Behavior, and Social Networking.

Unlocking long-hidden mechanisms of plant cell division
In a new paper by cell biologist Magdalena Bezanilla of the University of Massachusetts Amherst, she and her doctoral student Shu-Zon Wu present a detailed new model that for the first time proposes how plant cells precisely position a 'dynamic and complex' structure called a phragmoplast at the cell center during every division and how it directs cytokinesis. The work is reported in the current issue of the journal, eLife.

Smallest-possible diamonds form ultra-thin nanothread
A team has, for the first time, discovered how to produce ultra-thin 'diamond nanothreads' that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymer fibers. Such exceedingly strong, stiff, and light materials have an array of potential applications, everything from more-fuel efficient vehicles or even the science fictional-sounding proposal for a 'space elevator.'

Goats better than chemicals for curbing invasive marsh grass
Herbivores, not herbicides, may be the most effective way to combat the spread of Phragmites australis, one of the most invasive plants now threatening East Coast salt marshes. A new Duke-led study finds allowing small herds of goats and other livestock to graze in severely affected marshes can reduce phragmites cover from 94 percent to 21 percent and help restore natural species diversity, marsh function, and valuable shoreline views of the water.

Can genetic engineering help food crops better tolerate drought?
The staggering growth rate of the global population demands innovative and sustainable solutions to increase food production by as much as 70-100 perecnt in the next few decades. In light of environmental changes, more drought-tolerant food crops are essential. The latest technological advances and future directions in regulating genes involved in stress tolerance in crops is presented in a Review article in OMICS: A Journal of Integrative Biology.

Solar cell compound probed under pressure
Gallium arsenide a semiconductor composed of gallium and arsenic is well known to have properties that promise practical applications. In the form of nanowires it has particular potential for use in solar cell manufacture and optoelectronics in many of the same applications that silicon is commonly used. But its natural semiconducting ability requires tuning to make it more desirable for use in manufacturing. New work offers a novel approach to such tuning.

New research outlines promising therapies for small cell lung cancer
Two recently published studies by a research team at University Hospitals Case Medical Center Seidman Cancer Center have the potential to advance treatments for small cell lung cell cancer. This aggressive form of lung cancer has seen no treatment advances in 30 years and 'is a disease in urgent need of new drug therapies,' write the study's authors.

Study identifies gauntlet of obstacles facing migrating pronghorn in greater Yellowstone
One of North America's last remaining long-distance land migrations, better known as the Path of the Pronghorn, is being threatened by a mosaic of natural gas field development, highway traffic, and fencing in the upper Green River Basin, according to the Wildlife Conservation Society. WCS scientists used a model traditionally applied to identify resource related stopovers for migrating animals in order to identify impediments to migration of pronghorn.

New study shows that yoga and meditation may help train the brain
New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases.

How the ends of chromosomes are maintained for cancer cell immortality
Maintaining telomeres is a requisite feature of cells that are able to continuously divide and also a hallmark of human cancer. Telomeres are much like the plastic cap on the ends of shoelaces -- they keep the ends of DNA from fraying. In a new study published this week in Cell, researchers describe a mechanism for how cancer cells take over one of the processes for telomere maintenance to gain an infinite lifespan.

Brazilian zoologists discovered the first obligate cave-dwelling flatworm in South America
Typical cave-dwelling organisms, unpigmented and eyeless, were discovered in a karst area located in northeastern Brazil. The organisms were assigned to a new genus and species of freshwater flatworm and may constitute an oceanic relict. They represent the first obligate cave-dwelling flatworm in South America. The genus and species names honor a Hungarian biologist who immigrated to Brazil and studied freshwater flatworms over many years. The study was published in the open access journal ZooKeys.
