#To avert mass extinction, is genetic engineering the best option? Cornell University rightoriginal Studyposted by Blaine Friedlander-Cornell on September 30 2013with estimates that 15 to 40 percent of the world s species will be lost over the next 40 years due to warming
and habitat loss researchers are considering the option of a genetic rescue. The technique would involve escuing a target population

To avert mass extinctions the group thinks that three options each with its own set of challenges complications
The Nature commentary draws from a recent workshop cological and Genomic Exploration of Environmental Changethat occurred in March where scientists met to understand issues surrounding climate change adaptation.
Averting climate change altogether would be a preferableâ##albeit unlikelyâ##outcome. The scientists fear that implementing genetic solutions could potentially deter other climate change action. serious concern is that even the possibility of using genetic-engineering tools to rescue biodiversity will encourage inaction with regard to climate change.
Before genetic engineering can be entertained seriously as a tool for preserving biodiversity conservationists need to agree on the types of scenario for which facilitated adaptation managed relocation
#Is this mineral to blame for deep earthquakes? University of Chicago rightoriginal Studyposted by Steve Koppes-Chicago on September 25 2013scientists are closer to understanding deep earthquakes which occur
when tectonics drive the oceanic crust under continental plates. Their new research is a large step toward replicating the full power of these earthquakesâ##to learn what sets them off
-triggered brittle failures during the olivine-spinel (mineral) phase transformation has many similar features to deep earthquakes. ang
and a team of scientists simulated deep earthquakes by using a pressure of 5 gigapascals more than double the previous studies of 2 GPA.
and erupt into violent earthquakes yet it does. And that has puzzled scientists since the phenomenon of deep earthquakes was discovered nearly 100 years ago.
Interest spiked with the May 24 2013 eruption in the waters near Russia of the world s strongest deep earthquakeâ##roughly five times the power of the great San francisco quake of 1906.
These deep earthquakes occur in older and colder areas of the oceanic plate that gets pushed into the earth s mantle.
It has been speculated that the earthquakes are triggered when a mineral common in the upper mantle olivine undergoes a transformation that weakens the whole rock temporarily causing it to fail. ur current goal is to understand why
and how deep earthquakes happen. We are not at a stage to predict them yet.
More than 20 years ago geologist Harry Green of University of California Riverside and colleagues discovered a high-pressure failure mechanism that they proposed then was sought the long mechanism of very deep earthquakes (earthquakes
and showed that it coincides with the locations of deep earthquakes. In the September 20 issue of Science Green and colleagues explain how to simulate these earthquakes. e confirmed essentially all aspects of our earlier experimental work
and extended the conditions to significantly higher pressuregreen says. The ability to do such experiments allows scientists like Green to simulate the appropriate conditions within the Earth
which earthquakes happen at hundreds of kilometers depth. The origin of deep earthquakes fundamentally differs from that of shallow earthquakes (earthquakes occurring at less than a depth of 50 kilometers/31 miles.
In the case of shallow earthquakes theories of rock fracture rely on the properties of coalescing cracks
and friction. ut as pressure and temperature increase with depth intracrystalline plasticity dominates the deformation regime
and undergoes a transformation resulting in spinel a mineral of higher density. he research team focused on the role that phase transformations of olivine might play in triggering deep earthquakes.
and found the arthquakesonly within a narrow temperature range that simulates conditions where the real earthquakes occur in Earth. sing synchrotron X-rays to aid our observations we found that fractures nucleate at the onset of the olivine to spinel transitiongreen says. urther these fractures propagate dynamically
These phase transitions in olivine we argue in our research paper provide an attractive mechanism for how very deep earthquakes take place. ang says researchers next goal is to study the material silicate olivine which requires much higher pressures.

The manufacturing of Roman concrete also leaves a smaller carbon footprint than does its modern counterpart.
That process is responsible for seven percent of global carbon dioxide emissions every year. The production of lime for Roman concrete is much cleaner requiring temperatures that are two-thirds of that required for making Portland cement.#
#Roman concrete has remained coherent and well-consolidated for 2000 years in aggressive maritime environments#says Marie Jackson a research engineer in civil and environmental engineering at University of California Berkeley.#
Of particular interest to researchers is how Roman#s underwater concrete endured the unforgiving saltwater environment.
The recipe for Roman concrete was described around 30 BC by Marcus Vitruvius Pollio an engineer for Octavian who became Emperor Augustus. The not-so-secret ingredient is volcanic ash
whether volcanic ash would be a good large-volume substitute in countries without easy access to fly ash an industrial waste product from the burning of coal that is commonly used to produce modern green concrete.#
#Many countries don t have fly ash so the idea is to find alternative local materials that will work including the kind of volcanic ash that Romans used.

while sensors onboard collect and send in real time the data scientists need to predict the intensity and trajectory of storms:
#Our vehicles don t fight the hurricane; we use the hurricane to take us places#says Kamran Mohseni professor in the department of mechanical and aerospace engineering and the department of electrical and computer engineering at the University of Florida.
The aerial and underwater vehicles just six inches long and about the weight of an ipod Nano can be launched with commands from a laptop hundreds of miles from the eye of a hurricane.
Mohseni and colleagues use mathematical models to predict regions in the atmosphere and ocean that can give the vehicles a free ride toward their destination.
In essence they can go for a fact-gathering ride on hurricane winds and waters. The devices are a departure from current technology
which uses hurricane reconnaissance aircraft to punch through a storm#s eye wall and release dropsondes sensors that free-fall
although just as important considering that the warm moist air on the ocean surface provides fuel for hurricanes.
The new vehicles which can be launched hundreds at a time also reduce the cost of hurricane reconnaissance.#

With proper funding the vehicles could be tested in a real-world hurricane in two or three years.
