New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Light, meet matter: Single-photon quantum memory in diamond optical phonons at room temperature
(Phys.org)—Photonic quantum technologies – including cryptography, enhanced measurement and information processing – face a conundrum: They require single photons, but these are difficult to create, manipulate and measure. At the same time, quantum memories enable these technologies by acting as a photonic buffer. Therefore, an ideal part of the solution would be a single-photon on-demand read/write quantum memory. To date, however, development of a practical single-photon quantum memory has been stymied by (1) the need for high efficiency, (2) the read/write lasers used introducing noise that contaminates the quantum state, and (3) decoherence of the information stored in the memory.

Important step towards quantum computing: Metals at atomic scale
German scientists from RWTH Aachen, Research Center Jülich, TU Dresden and of the Leibniz Institute for Solid State and Materials Research Dresden report that the current flow on the surface of a topological insulator is channeled along tiny paths, which have been theoretically calculated and experimentally observed. Their work has been published in the issue from March 2, 2015 of the journal Nature Physics. The team shows for Bismuth-Rhodium-Iodine that these channels are tied to one dimensional surface features and run along steps formed by the edges of atomic layers. Scanning tunneling spectroscopy reveals the electron channels to be continuous in both energy and space and less than one nanometer wide.

Did climate change help spark the Syrian war?
A new study says a record drought that ravaged Syria in 2006-2010 was likely stoked by ongoing manmade climate change, and that the drought may have helped propel the 2011 Syrian uprising. Researchers say the drought, the worst ever recorded in the region, destroyed agriculture in the breadbasket region of northern Syria, driving dispossessed farmers to cities, where poverty, government mismanagement and other factors created unrest that exploded in spring 2011. The conflict has since evolved into a complex multinational war that has killed at least 200,000 people and displaced millions. The study appears today in the leading journal Proceedings of the National Academy of Sciences.

New insight into carbon emissions from big carbon sinks in peat bogs
Flooding is the way of life in peat bogs. The standing water helps create an environment where mosses, sedges and shrubs flourish. As each year passes, a thick new layer of vegetation buries the old. Layer and layer of partially decomposed organic matter piles into peat, which slowly gathers and stores tons of carbon over centuries. With so much old plant material trapped in them, these flooded peat bogs affect much bigger carbon and climate systems.

An old-looking galaxy in a young universe
A team of astronomers, led by Darach Watson, from the University of Copenhagen used the Very Large Telescope's X-shooter instrument along with the Atacama Large Millimeter/submillimeter Array (ALMA) to observe one of the youngest and most remote galaxies ever found. They were surprised to discover a far more evolved system than expected. It had a fraction of dust similar to a very mature galaxy, such as the Milky Way. Such dust is vital to life, because it helps form planets, complex molecules and normal stars.

Where do stars form in merging galaxies?
Collisions between galaxies, and even less dramatic gravitational encounters between them, are recognized as triggering star formation. Observations of luminous galaxies, powered by starbursts, are consistent with this conclusion. Numerical simulations also support this picture, with gravity funneling copious amounts of gas into the central regions of galaxies, fueling powerful bursts of star formation there. But starbursts are not ubiquitous in interacting galaxies. Triggering therefore depends on many factors, including the specific merger geometry (how they come together), the properties of the progenitor galaxies (how much gas is available for new stars), and time-scale (maybe the starburst has yet to happen, or has finished?)

Hunting transiting exoplanets
European Southern Observatory (ESO) gears up for the exoplanet hunting. The Next-Generation Transit Survey (NGTS), a wide-field observing system made up of an array of twelve telescopes was installed at ESO's Paranal Observatory in Chile. It will search for transiting exoplanets—planets that pass in front of their parent star and hence produce a slight dimming of the star's light that can be detected by sensitive instruments. "NGTS will have some sensitivity to habitable zone planets - these are planets at the right distance from their star that they would receive similar amounts of heat as the Earth does," Don Pollacco of the University of Warwick (UK) told astrowatch.net.

Mystery giant Mars plumes still unexplained
On Feb. 16, an international group of researchers proposed new hypotheses about some unusual plumes spotted by amateur astronomers on Mars in 2012. The plumes were seen rising to altitudes of over 250 km above. By comparison, similar features seen in the past have never exceeded 100 km. Now, new conclusions presented by scientists still raise more questions about the mysterious plumes, than they answer. "We tentatively explored two scenarios that might help explain the observed phenomenon: a cloud of condensed CO2 or H2O, or even dust, and an aurora. After elaborating the details of these two hypotheses, we came to the conclusion that none of them provided a fully satisfactory answer," Antonio García Muñoz of ESA's European Space Research and Technology Centre (ESTEC), co-author of the paper reporting the results in the journal Nature, told astrowatch.net. "Therefore, we consider that the genuine nature of the phenomenon is stil! l an open issue."

New method makes space weather easier to predict
Scientists can now gain a better understanding of space weather – the dreaded solar winds and flares – thanks to the development of high spatial resolution observation and computing methods. For the first time, it will thus be possible to study the interrelated events that occur on the sun and trigger solar activity. To this effect, a current project funded by the Austrian Science Fund FWF is in the process of developing new methods that can generate three-dimensional images and will allow scientists to study the chronological sequence and evolution of processes taking place in the sun's interior. These new methods will make it possible to link detailed observational data about the sun with complex computer simulations of solar activity.

The huge "Y" in the atmosphere of Venus due to a wave distorted by the wind
Venus is covered by a dense layer of clouds which does not display any noteworthy characteristic. However, when looked in the ultraviolet wavelength, it presents conspicuous dark structures. The biggest one, which practically covers the entire planet, is shaped like a "Y" and it has been a mystery since its discovery more than half a century ago. Recently, a study led by astronomers from the Institute of Astrophysics of Andalusia (IAA-CSIC), in collaboration with the university of the Basque Country and the Institute of Astrophysics and Space Sciences of Portugal, has described the mechanism that sustains this structure and has for the first time succeeded in reproducing its evolution in the course of one month.

What is up with the fossils on Mars? Found – a dinosaur skull on Mars? Discovered – a rat, squirrel or gerbil on Mars? In background of images from Curiosity, vertebrae from some extinct Martian species? And the human skull, half buried in photos from Opportunity Rover. All the images are made of stone from the ancient past and this is also what is called Pareidolia. They are figments of our imaginations, and driven by our interest to be there – on Mars – and to know that we are not alone. Altogether, they make a multitude of web pages and threads across the internet.

Personalized factory workstations
Tomorrow's factory jobs will be completely different from those of today. Although they will continue to be organized around assembly stations, they will not work in rigid shifts, be subject to inflexible processes, or be restricted to a single workstation. According to Johannes Scholz and Johannes Labuttis, engineers who studied mechanical engineering at the Technical University of Munich, in 15 years most monotonous and strenuous activities will probably be a thing of the past. Scholz and Labuttis now work at Siemens Corporate Technology in Munich, where they focus on the role of humans in production processes. "In the future, workers will use their smartphones and computers to organize their shifts themselves," says Scholz. "When doing so, they will be able to take into account their personal chrono-biological attributes – for example, whether they're day people or night people. This will enable them to adapt their work assig! nments to their private needs and personal situations"

Mind-readers: Scientists crack a piece of the neural code for learning and memory
It sounds like the stuff of science fiction: researchers slice a brain into thin little sections and, just by measuring the properties of specific neurons, they can determine what an organism learned before it died. In fact, this sort of mind reading has become a reality. In work published today in Nature, researchers at Cold Spring Harbor Laboratory (CSHL) describe how postmortem brain slices can be "read" to determine how a rat was trained to behave in response to specific sounds. The work provides one of the first examples of how specific changes in the activity of individual neurons encode particular acts of learning and memory in the brain.

Researchers identify the mitochondrial 'shield' that helps cancer cells survive
Scientists have moved closer to understanding why cancer cells can be so resilient, even when faced with the onslaught of nearly toxic drug cocktails, radiation, and even our own immune systems. A new research report appearing in the March 2015 issue of The FASEB Journal, shows that intermediate filaments formed by a protein called "vimentin" or VIF, effectively "insulate" the mitochondria in cancer cells from any attempt to destroy the cell. Under normal circumstances, VIF serves as the "skeleton" for cells by helping them maintain their shapes. In some cancer cells, however, VIF actually help to preserve the cancer cell's center of energy, the mitochondria, either by helping the cell to resist outside assaults or by helping it recover quickly. Because a number of cancer treatments target the mitochondria of cancer cells, this discovery should help researchers develop new drugs that more effectively treat cancer.

Salmonella and Campylobacter show significant levels of resistance to common antimicrobials in humans and animals
Treatment options for some of the most common food-borne infections are decreasing, as types of bacteria (called 'isolates') continue to show resistance to antimicrobial drugs. For example, multi-drug resistant isolates of Salmonella continue to spread across Europe. Also, high resistance to the antimicrobial ciprofloxacin in Campylobacter isolates in both humans and animals has been reported in some Member States. Encouragingly, co-resistance to critically important antimicrobials for both bacteria remains low. These are some the findings of the latest EFSA-ECDC European Union Summary Report on antimicrobial resistance (AMR) in zoonotic and indicator bacteria from humans, animals and food, which analyses data from 2013.

Best of Last Week–Can space travel faster than light, another planet behind the Sun and should we allow head transplants
(Phys.org)—It was an interesting week for physics research—most of the big news was centered around space, the cosmos or how things came to be as they are. One team of physicists offered a solution to the puzzle of the origin of matter in the universe—suggesting that matter-antimatter asymmetry could be related to the Higgs boson particle. Another team wondered, how can space travel faster than the speed of light? If nothing can travel faster than light, they asked, how is it possible that there are parts of spacetime where the photons that make up light are forever out of our reach? And yet another team wondered if classical theory could be just as weird as quantum theory—they showed that objectivity, determinism, and independence are mutually incompatible with any theory.
