The discovery was made from observations by the Hubble Space Telescope and WISE, both NASA astronomical satellites, as well as the facilities of the Institute of Millimeter Radio Astronomy in the French Alps. SDSSJ1506 Galaxy drew +54 Jim attention Geach team at McGill University in Canada, and Ryan Hickox of Dartmouth College in Hanover, New Hampshire, USA, when observed using inspection records of the sky in the infrared made by WISE. Infrared light is coming out of the galaxy, equals more than 1 trillion (million million) times the energy of our sun The galaxy is so far away that infrared radiation has taken about 6,000 million years to reach us.

Through scanning the whole sky, the satellite has uncovered rare galaxies like this that stand out from the rest. Although this galaxy is forming stars at a rate hundreds of times faster than our galaxy, Hubble observations have revealed that most of the stellar light of the galaxy is being emitted from a region of a few hundred years lumen diameter, ie, only a small percentage of the diameter of the Milky Way.

SDSSJ1506 +54 Why is that unusual? Astronomers believe they are seeing the galaxy on a brief phase of its evolution, possibly caused by the merger of two galaxies into one. Star formation in SDSSJ1506 +54 is so prolific that a few tens of millions years, a blink in the life of a galaxy, the gas will run out, and mature +54 SDSSJ1506 becoming a massive elliptical galaxy.

schmitzi Camponotus ants live only in a species of carnivorous plant from Borneo, Nepenthes bicalcarata. Such ants are installed in a plant, and roam proficiently by slippery traps your living dwelling, swim and dive in the digestive juices of it, and consume the nectar and prey that fall into the trap. Though ants’ benefits are obvious, has been more difficult to explain what exactly the profit that plants obtain this relationship is.

However, they grow more than without ants, which already suggest a mutualistic relationship between the two species. bicalcarata The Nepenthes carnivorous plant (A) and the ant Camponotus schmitzi (B) maintain an alliance against mosquito larvae and some other flying insects comparable (C) intended to steal plant nutrients.

In the new study, the team Scharmann Mathias and colleagues at the University of Cambridge in the UK and the University of Brunei, has determined the benefits that the presence of ants has for their host plant. In addition to preventing mosquito larvae and some other flying insect’s stolen comparable nutrients to the plant, the ants appear to increase the efficiency of the plant hunter to keep clean their traps. In addition, the waste generated by the ant colony you are useful to the plant.

Now we want to test and determine how many aircraft can detect in practice, and what kind – as there are different categories of systems on board, whose power is related to the size of the aircraft. This study will pave the way for aircraft operationally monitored from space in the near future. The main objective of Proba-V mission, launched on May 7, is to study the evolution of the vegetation cover of our planet every two days. However, this mini satellite of less than one cubic meter also serves as a miniature laboratory to test new technologies in space. Among these ‘technology demonstrators’ is an experiment designed to detect radio signals from the Automatic Dependent Surveillance system ( ADS-B) issued by aircraft in flight, developed by DLR in cooperation with the Luxembourg company SES Techcom.

Aircraft equipped with ADS-B systems emit a signal at regular intervals containing information about your speed, position and altitude. It is expected that in the coming years all aircraft crossing European airspace are equipped with this system. Currently being installed ADS-B receivers as part of the ground infrastructure for air traffic management, in addition to radar systems traditional. “However, most of the planet, and in very remote areas or over oceans, it is not economically viable or technically feasible to install ground equipment, whether radar or ADS-B receivers,” adds Delovski. In these situations, the ability to monitor air traffic from space offers great potential in terms of security – including the possibility of implementing search and rescue services in the airspace, which lies outside the coverage of ground equipment.

The advantages of removing these dead zones are evident. On the other hand, could allow to reduce the separation between aircraft in transit or open routes more efficient, increasing air traffic capacity and reducing fuel consumption and carbon dioxide emissions. “It’s another milestone Family ESA’s Proba satellite, designed to test new technologies in the European space,” says Frederic Teston, supervisor of the Proba satellite series from the ESA program responsible for providing opportunities flight to new technologies.

Proba-V is a miniaturized satellite of ESA with a major mission: monitor vegetation growth and evolution of land cover globally every two days. Is currently in the commissioning phase orbit. The new family member Proba small low-cost space missions, designed to test new space technologies in Europe. Besides its main tool for the study of vegetation, Proba-V also carries a number of technology demonstrators. Among these secondary payloads are two innovative radiation detectors, amplifier communications semiconductor based high performance nitride gallium, and fiber optic connectors, high-capacity and low weight.

A team of scientists from Tel Aviv University in Israel, and the Center for Astrophysics (CfA) in Cambridge, Massachusetts, managed jointly by Harvard University and the Smithsonian Institute, these three institutions in the United States, has recently discovered an exoplanet by using a new method, which is based in part on the theory of relativity of Einstein. CfA Avi Loeb and his colleague Scott Gaudi (now at Ohio State University) first proposed the technique in 2003. (Incidentally, they developed their theory on technique while visiting the Institute for Advanced Study in Princeton, where Einstein worked.

The new method, implemented by the team of David Latham CfA and Mazeh Simchon Tsevi Faigler and University Tel Aviv, is based on capturing three small effects that occur at the same time as a planet revolves around its star. Explained simply, are a subtle brightening and darkening, stretching Subtle Star by gravity on the planet, and a spillover effect of starlight reflected by the planet. “This is the first time that has used this facet of the theory of relativity of Einstein to discover a planet “emphasizes Mazeh. Having identified the new planet, was confirmed by Latham using radial velocity observations made at the Whipple Observatory in Arizona, and Lev Tal-Or (Tel Aviv University) at the Observatories de Haute-Provence in France.

A detailed analysis of data collected by the Kepler Space Telescope also showed that the planet makes transits in front of its star, which provided further confirmation. “Planet of Einstein”, formally known as Kepler-76b, is a “hot Jupiter “giving a full turn around its star in just a half day. Its diameter is about 25 percent larger than Jupiter and its mass is about twice that of Jupiter. The star around which it orbits is more massive and hotter than the Sun, and is about 2,000 light-years away from Earth, in the constellation Cygnus. The planet always shows the same face to the star, as Moon does to the Earth. As a result, Kepler-76b reaches a temperature of about 2,000 degrees Celsius (3,600 degrees Fahrenheit) in the hemisphere which is always day.

However, Fermi, as NASA has recollected recently ran a year ago with a situation that required him to make an evasive maneuver. all started when Julie McEnery, scientific Fermi Space Telescope team of gamma rays, NASA, received a notice indicating that Fermi was only a week to have an unusually close encounter with the Cosmos 1805, a defunct spy satellite Cold War era. This spy satellite would pass dangerously close to the Fermi. It was estimated that the two objects, traveling around the Earth at thousands of miles per hour in orbits nearly perpendicular, were avoided by just 213 meters (700 feet).

It appeared that both spacecraft occupy the same point in space with 30 milliseconds of difference with respect to each other. Clear that the Fermi had to make an evasive maneuver. Nevertheless, it is not as easy as it and problem solved. In the history of astronautics, the staff of the flight control centers spacecraft has learned the hard way that one cannot ignore the letter to a collision prediction. The margins of uncertainty in predictions of spacecraft positions with a week in advance can be much larger than the distance itself predicted for the time of maximum closeness. In other words, make a maneuver to dodge the Cosmos 1805 did not ensure collision avoidance, and even, paradoxically, could cause it. On the other hand, doing nothing is also dangerous. Close encounters can end badly, because the safety distance is not fixed. This was dramatically demonstrated the February 10, 2009, when according to a study, the Cosmos 2251 a dead Russian communications satellite would pass about 580 meters (about 1,900 feet) communications satellite Iridium 33 (operating at the time).

The expected approach time, all contact was lost with the Iridium 33. The radar revealed debris clouds traveling along the orbits of the two satellites, which confirmed the collision between them. The accident generated thousands of pieces large enough to be tracked, and many small pieces, which cannot be detected. Many remains are still a hazard to operational spacecraft, and that only about 20 percent of traceable fragments have made their re-entry into the atmosphere. With a relative to the Fermi velocity of about 43,000 mph (27,000 miles per hour), a direct impact of the Cosmos 1805, of 1,406 kilograms (3,100 pounds), would release as much energy as two and a half tons of high explosives, destroying both ships.

Despite the apparent crowding of objects in Earth orbit, usually there are a lot of empty space between each object and the closest. The approximations between fragments of vessels, rocket stages and active loads remain rare events. Moreover, only some of the possible approaches that are identified about a week before when they could happen to materialize. “is similar to the forecast of rain in a specific time and place one week in advance,” explains Eric Stoneking , the Goddard Space Flight Center NASA’s chief engineer Fermi position control. “As the date approaches, the prediction uncertainties decrease and the initial forecast can change dramatically.” Twice before, the Fermi team had been alerted to possible close encounters, and both times the threats were evaporated without having to do anything.

Could the 1805 Cosmos meeting also vanish, and that the Fermi could continue with his astronomical observations without having to interrupt them. However, the next day the update did not dispel the threat whatsoever. “It was clear we had to be ready to take the Fermi out of the way and that’s when our team warned Flight Dynamics “recalls McEnery. The only way to achieve that crucial career change was resorting to temporary ignition engines originally designed to ensure that it does not represent one Fermi threat to other satellites when ended its life. Designed for use when the Fermi longer in service.

The engines were designed to remove the orbit and push the Earth’s atmosphere, which would burn and fall apart. Due to a failure of this system of thrusters, for example, propellant leak or explosion could have ended prematurely Fermi mission, these engines had never been tested, which added a new source of anxiety for McEnery and colleagues. Proponents should work perfectly on your first use, and to do something that had not been contemplated in their design. Calculated how big should be the push to give the Fermi esquivase the threat. Working with specialists from Vandenberg, the U.S. Air Force (USAF) has in California, NASA scientists also found that the new projected orbit Fermi did not put the course of a close encounter with another object.

The day before the meeting date, the threat had not disappeared, and consequently all were active plans to turn the propellers of Fermi. Shortly after noon, EDT time, the ship stopped scanning the sky and oriented along the direction of their march. Then said its solar panels and retracted its high-gain antenna to protect it from the exhaust gases of the engines. ‘s move, which was executed by the ship itself, based on the procedures developed by the technical team long ago, consisted on all thrusters firing for a second. “There was so much suspense and tension, but once completed the maneuver, sighs with relief that all had gone well,” says Stoneking. An hour later, he was back Fermi doing scientific work. Several hours later, the different teams gathered to evaluate the results of the maneuver and determine if you need another. It was confirmed that the prognosis was good. When the two ships reached their close encounter the next day, the closest approach between the two was more than 9 kilometers (about 6 miles). Evasion maneuver had succeeded Fermi Space Telescope eluded the looming Cold War relic. The scientists invaded relief after a week of maximum tension.

The project CALIFA observe a sample of about 600 galaxies in the local universe selected over more than 200 nights of observations with the 3.5 m Zeiss telescope of Calar Alto Observatory. For this study will engage the telescope the Spectrophotometer PMAS / PPAK, one of the best integral field spectrographs worldwide.

Integral Field Spectroscopy:
The telescopes are not always used for imaging “normal” photographs like snapshots that can be taken with standard cameras. On the contrary, very often-astronomical telescopes are equipped with spectrographs, instruments that break down light into its constituent colors. Thus telescopes capture the spectrum (the ‘rainbow’) produced by the light from the stars or galaxies. The non-imaging spectrographs spectacular that can be used to decorate the walls of showrooms but provide an overwhelming amount of physical information about astronomical objects.

Until recently, the spectrographs were able to obtain spectra of only a very limited number of objects in each shot. Nevertheless, new technology of integral field spectroscopy allows many simultaneous spectra taken. This is achieved thanks to an ingenious combination of optical fibers and conventional spectroscopic techniques. The integral field spectrograph serving in the Calar Alto Observatory, PMAS, in a special configuration called PPAK employs more than 350 optical fibers to cover a field of view of one minute of arc (which equals the size of a quarter of a euro placed about 80 meters away).

This will be completely mapped throughout an extended object such as a galaxy, in one shot. This instrument attached to the 3.5 m Zeiss telescope of Calar Alto is able to obtain data from the same quality as a classical spectrograph combined with a class telescope 10 meters, but at a rate more than 20 times higher. PMAS (Potsdam Multi-Aperture Spectrophotometer) was built in the Institute of Astrophysics in Potsdam under the direction of MM Roth.

CALIFA provide the integral field spectroscopic study longer made to date of galaxies, and provide relevant data about several key points related to the structure and evolution of galaxies: stellar populations modeling, restrictions on the history of star formation, marking the gas content, chemical composition determination and analysis of the internal motions of these stellar systems, among others.

Intensively exploited CALIFA exceptional benefits PMAS / PPAK, and cover the gap between the studies conducted so far with single aperture spectrographs and other more detailed surveys conducted on individual galaxies. CALIFA consortium includes more than 50 astronomers from five different countries scientists whose interests will benefit from the resulting data.

However, the objective of this project goes beyond this ambitious scope, albeit limited, because CALIFA put the data (both raw and treated) directly available to the public, along with tools suitable for analysis. From this point of view, this project is listed as one of the most open made to date at Calar Alto, and we hope to define a new model for the treatment of the data produced in the future in these facilities.

Senate Bill 1972 was passed by the House at a vote of 77 to 38 in its final stage before heading to the Governor for his approval. Medical groups have been lobbying for this type of change for several years and is now being seen as a sizeable victory in the effort to help to protect doctors from expensive lawsuits. The bill had already been approved by the Senate.

The primary focus of the bill – which was sponsored in the House by Rep. Matt Gaetz (R-Fort Walton Beach) – is in the process of malpractice cases, instead of on the higher-profile issues, such as limits to the size of legal damages that can be awarded. For instance, it would require that within malpractice cases, expert witnesses must have the same specialties as the doctors who have been sued. At the moment, the standard allows expert witnesses to be admissible when they have similar specialties, even if they are not the same.

According to a prepared statement by Vincent DeGennaro, the president of the Florida Medical Association, “For years, we have fought to correct unfair imbalances in the tort system that are hostile to doctors.” He went on to say that the approval of SB 1972 “isn’t just a victory for physicians. Making our state a friendlier place to practice medicine attracts more doctors to Florida, which increases Florida patients’ access to care.”

Opponents to the bill include the trial lawyers’ group, the Florida Justice Association, which had been fervently lobbying against the bill. It maintains that tighter legal restrictions will make it more difficult for the victims of malpractice to be able to receive their due compensation for the injuries that they have sustained.

The bill’s supporters have said that this measure helps to make certain that witnesses in medical malpractice lawsuits are adequately experienced and qualified to testify on the actions that were taken by the doctors in the defendants’ seats. To this, opponents have responded that this considerably shrinks the expert witness pool who will be considered qualified and who will also be willing to provide testimony against doctors.

Aging is a major risk factor for the emergence and progression of many neurodegenerative diseases. In that sense, the team of David Walker and Anil Rana believes the new finding provides key insight into the molecular mechanisms that connect these processes. Parkin gene may regulate the aging process in fruit flies, which as a rule usually live less than two months. Levels increased researchers parkin gene in cells of flies studied, and found that this extended life by more than 25 percent compared to a control group in which no enhanced flies that gene.

Left, fly brain tissue with normal aging. To the right of fly brain tissue where the parkin gene is over expressed. When this gene is over expressed, there is less accumulation of protein aggregates, shown in green. In red appear cytoskeleton protein, and the cell nuclei are shown in blue. (Images: Anil Rana / UCLA Life Sciences) All flies in the control group had died on day 50. In contrast, in the group with parkin gene over expressed, nearly half of the population of those still living after 50 days.

Moreover, this, having handled only one of its nearly 15,000 genes. With only increase levels of parkin, flies live significantly longer without their health experience harmful side effects. They live longer, but staying active, fertile and ultimately healthy. The latter is important because, as argued Anil Rana, what is sought with this line of research is not only extend life but also the stage of overall health is still good, before the general deterioration associated with senility.

Bacteria biofilms behave quite differently to bacteria unorganized. Within biofilms, bacteria change their genetic expression patterns and become more resistant to antibiotics and the body’s immune defenses that bacteria invaded unorganized, either grouped in a way that benefits them, being protected by a matrix of proteins, DNA and molecules like long chains of sugars called polysaccharides. Gerard Wong’s team at UCLA, Erik Luijten Northwestern University and Matthew R. Parsek Washington University, has clarified the puzzle of how exactly starts bacterial biofilm formation.

For research algorithms have been developed that describe the movement of the different strains of the bacterium Pseudomonas aeruginosa and computer simulations have been performed for mapping the movements of the bacteria. The P. aeruginosa can cause infections hard to treat and capable of causing death. Like people attracted by the amenities of the cities, the bacteria use established routes to converge on high traffic sites and organized in large colonies, in a way reminiscent of the spontaneous process of building a city on an uninhabited place, as, for example, building a road or a railway line, as in many cities in the United States, born with the expansion of the railroad.

Surprisingly, researchers found that individual bacteria that initiate the formation of microcolonies no special inherent qualities. As bacteria move across a surface, leave traces that include compounds of a specific type of polysaccharide called Psl. Some bacteria are fixed in position. However, others move along the surface here and there, seemingly at random, but leaving a trail then influencing the behavior of other bacteria that find that trail. Bacteria arriving later also leave traces, but their movements tend to be guided by the traces left by the first bacteria. This network of trails, for road network that facilitates the installation of new infrastructure in undeveloped site, to finally build a city, creates a positive feedback process allows bacteria are organized in microcolonies that biofilms become, bacterial large cities. Research in Kun Zhao has also worked at UCLA and Boo Shan Tseng of the University of Washington.

These interfaces cannot use that move, modify or delete similar gestures, making them highly personalized. Researchers at the Institute of Human-Computer Interaction (HCII) at Carnegie Mellon used a projector and a camera attached to the ceiling to record geometries of the room, hand gestures perceive and project images in the desired surfaces. However, Robert Xiao, the HCII, believes requires no installation worldKit as elaborate.

He argues that the depth sensors are getting better, and getting smaller projectors. Given these developments, he and his colleagues have devised a “bulb” interactive miniature device could be screwed to a table lamp and aimed or moved to where you need an interface. The system requires no prior calibration, as it automatically adjusts the perception and imaging to the chosen surface orientation.

Users can arise not only remote controls or keyboards, but also switches, bulletin boards, indicator lights and a wide range of other interface designs from a menu offered by the system. The team anticipates worldKit creator, ultimately, users can easily design custom interfaces using gestures. Xiao worldKit system has been developed with Scott Hudson and Chris Harrison.
