Im Focus: Permafrost soil is possible source of abrupt rise in greenhouse gases at end of last ice age

Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have identified a possible source of carbon dioxide (CO2) and other greenhouse gases that were abruptly released to the atmosphere in large quantities around 14,600 years ago.

According to this new interpretation, the CO2 – released during the onset of the Bølling/Allerød warm period – presumably had their origin in thawing Arctic...

Im Focus: Small volcanic eruptions could be slowing global warming

Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth’s upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to a new study.

Scientists have long known that volcanoes can cool the atmosphere, mainly by means of sulfur dioxide gas that eruptions expel. Droplets of sulfuric acid that...

Im Focus: Researchers discern the shapes of high-order Brownian motions

For the first time, scientists have vividly mapped the shapes and textures of high-order modes of Brownian motions--in this case, the collective macroscopic movement of molecules in microdisk resonators--researchers at Case Western Reserve University report.

The new technology holds promise for multimodal sensing and signal processing, and to develop optical coding for computing and other information-processing...

Im Focus: New form of crystalline order holds promise for thermoelectric applications

Since the 1850's scientists have known that crystalline materials are organized into fourteen different basic lattice structures. However, a team of researchers from Vanderbilt University and Oak Ridge National Laboratory (ORNL) now reports that it has discovered an entirely new form of crystalline order that simultaneously exhibits both crystal and polycrystalline properties, which they describe as "interlaced crystals."

Writing in the Nov. 14 issue of the journal Nature Communications, the researchers describe finding this unusual arrangement of atoms while studying...

Im Focus: A Piece of the Quantum Puzzle

UCSB physicists demonstrate the high level of controllability needed to explore ideas in quantum simulations

While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been...

Im Focus: Successful landing: Philae reports from the surface of the comet 67P/Churyumov-Gerasimenko

November 12, 2014 goes down in history. On this Wednesday, an unmanned probe landed on a comet nucleus for the first time ever. Philae is to remain there as a permanent research station to collect data and take measurements for at least 60 hours. On its way to 67P/Churyumov-Gerasimenko, Philae followed a precisely defined choreography.

Already on 8 November, the ground crew sent the computer sequence that controlled the landing to Philae via the orbiter. On Monday, the lander was switched on...

Im Focus: Towards future lab-on-chip applications

Fraunhofer FEP presents latest approaches to fabricate OLED devices for lab-on-a-chip-applications using either near UV electroluminescence (EL) or optically modulated green light to stimulate fluorescent dye markers.

Smart and portable medical equipment is essential for fast and easy point-of-care and point-of-use diagnostics. Lab-on-a-chip applications in hand-held devices...

Im Focus: More methane from the deep sea: Mud-volcanoes as methane source

The mud-volcano Haakon Mosby in the Barents sea near Norway emits yearly several hundred tons of methane, a potent greenhouse gas. A research team, coordinated by the Max-Planck-Institute in Bremen, reports on the results of a long-term observatory in NATURE Communications.

They collected during 431 days data on temperature, pressure and pH and documented using a camera 25 eruptions of mud and gas. Some of these eruptions were so...

Im Focus: Good Vibrations Give Electrons Excitations That Rock an Insulator to Go Metallic

In a vanadium dioxide crystal, shaking of lattice atoms unlocks electron flow

For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow...

Im Focus: European satellite could discover thousands of planets in Earth's galaxy

A recently launched European satellite could reveal tens of thousands of new planets within the next few years, and provide scientists with a far better understanding of the number, variety and distribution of planets in our galaxy, according to research published today.

Researchers from Princeton University and Lund University in Sweden calculated that the observational satellite Gaia could detect as many as 21,000 exoplanets,...
