Antarctic glaciation caused ocean circulation changes at the Eocene-Oligocene transition

Two main hypotheses compete to explain global cooling and the abrupt growth of the Antarctic ice sheet across the Eocene-Oligocene transition about 34 million years ago: thermal isolation of Antarctica due to southern ocean gateway opening and declining atmospheric CO2.

Robust ​carbon dioxide reduction on ​molybdenum disulphide edges

Electrochemical reduction of ​carbon dioxide has been recognized as an efficient way to convert ​carbon dioxide to energy-rich products. Noble metals (for example, ​gold and ​silver) have been demonstrated to reduce ​carbon dioxide at moderate rates and low overpotentials. ... Here we identify ​molybdenum disulphide as a promising cost-effective substitute for noble metal catalysts.

New research helps scientists predict impact on climate

When tiny sea organisms called phytoplankton die, they produce oils, proteins, and other molecules that tend to stick to ocean water bubbles. Rising to the surface, these bubbles break and form sea spray. The remains of the organisms are lofted into the air where the carbon they contain can influence the chemical makeup of the atmosphere. ... a multi-institutional team of researchers including scientists at Pacific Northwest National Laboratory described a method to understand which types of these carbon-containing materials are prevalent in different parts of the ocean.

50-foot-wide Muon g-2 electromagnet installed at Fermilab

One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the U.S. Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from Long Island, New York. This week, the magnet took the final few steps of that journey, moving across the Fermilab site and into the new building that now houses it.

Simulation models optimize water power

The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20 000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system.

Free pores for molecule transport

Metal-organic frameworks (MOFs) can take up gases similar to a sponge that soaks up liquids. Hence, these highly porous materials are suited for storing hydrogen or greenhouse gases. However, loading of many MOFs is inhibited by barriers. Scientists of Karlsruhe Institute of Technology now report in Nature Communications that the barriers are caused by corrosion of the MOF surface. This can be prevented by water-free synthesis and storing strategies. (http://dx.doi.org/10.1038/ncomms5562)

Chemists demonstrate 'bricks-and-mortar' assembly of new molecular structures

Chemists at Indiana University Bloomington have described the self-assembly of large, symmetrical molecules in bricks-and-mortar fashion, a development with potential value for the field of organic electronic devices such as field-effect transistors and photovoltaic cells.

Neutron tomography technique reveals phase fractions of crystalline materials in 3-dimensions

The method overcomes limitations of existing techniques which are limited to the surface or small-sized specimens, and allows a 3-D representation of the phase fractions within the sample volume. (http://dx.doi.org/10.1002/adma.201400192)

Panasonic. Tesla to build big US battery plant

(AP) - American electric car maker Tesla Motors Inc. is teaming up with Japanese electronics company Panasonic Corp. to build a battery manufacturing plant in the U.S. expected to create 6,500 jobs. ... The plant will produce cells, modules and packs for Tesla's electric vehicles and for the stationary energy storage market, employing 6,500 people by 2020.

Deadliest Ebola Outbreak in History Could Spread to US

Now recognized as the largest Ebola outbreak in history, the most recent eruption of the disease in three countries in West Africa - Guinea, Liberia and Sierra Leone - has claimed more than 670 victims, spurring international concern that the disease is only a plane ride away from spreading to other countries, including the United States.

Inside Lawrence Livermore and the arms race for innovation

Lawrence Livermore has the world's third-fastest supercomputer with the help of IBM. But China now holds the number one slot. And while the Livermore Lab has the world's largest laser, France, China and Russia are pursuing super lasers of their own. ... But first-mover advantages can also help secure medicine such as a cancer treatment or an Ebola vaccine. And there are national security consequences to such information.

Three ways Middle East fighting threatens US national security

Pentagon analysts are increasingly grappling with what this growing unrest means for US national security. Here are the top three ways the advance of the insurgent group the Islamic State in Iraq and violence in Gaza could endanger US national security.

TSA Employees Union Says Airport Security Privatization Jeopardizes Passenger Safety

American Federation of Government Employees (AFGE) National President J. David Cox, Sr. told the House Committee on Homeland Security’s Subcommittee on Transportation Security he opposes the Transportation Security Administration's (TSA) Screening Partnership Program (SPP), an initiative that facilitates privatization of airport security.

FACT SHEET: Fair Pay and Safe Workplaces Executive Order

While the vast majority of federal contractors play by the rules, every year tens of thousands of American workers are denied overtime wages, not hired or paid fairly because of their gender or age, or have their health and safety put at risk by corporations contracting with the federal government that cut corners.
