OGLE uses the 1.3-m Warsaw Telescope located at Las Campanas Observatory in Chile, while MOA utilizes the 1.8-m MOA-II telescope at the Mount John University Observatory, located in New Zealand. The main goal of these two microlensing surveys is to study the planet formation around late-type stars.Gravitational microlensing is an invaluable method of detecting new extrasolar planets circling their parent stars relatively closely. This technique is sensitive to planets orbiting beyond the so-called “snow line” around relatively faint host stars like M dwarfs or brown dwarfs. It is a location in the proto-planetary disk where the water ice may condense and where gas giant planets are believed to be formed. Therefore, understanding the distribution of exoplanets in this region could offer important clues to how planets form.Recently, OGLE and MOA scientists led by Przemek Mróz of the Warsaw University Observatory in Poland, have found planetary anomalies in two faint microlensing events designated OGLE-2013-BLG-0132 and OGLE-2013-BLG-1721. “Both events showed clear deviations from the simple point-source point-lens model, caused by the presence of a second body with well-measured planet-to-host mass ratios of (5.15 ± 0.28) x 10-4 and (13.18 ± 0.72) x 10-4, respectively,” the researchers wrote in the paper.The newly discovered planets received designation OGLE-2013-BLG-0132b and OGLE-2013-BLG-1721b. Both planets likely belong to a group of sub-Jupiter-mass planets orbiting M dwarfs beyond the snow line distance.According to the research, OGLE-2013-BLG-0132b has a mass of about 0.29 Jupiter masses and orbits its parent star at a distance of 3.6 AU. The planet’s host is located about 12,700 light years away and has a mass of approximately 0.54 solar masses. With a mass of about 0.64 Jupiter masses, OGLE-2013-BLG-1721b is circling its host (0.46 solar masses) at a distance of 2.6 AU. This planetary system is located some 20,500 light years away from the Earth.The researchers estimated the masses of the planets using the Bayesian analysis as both events were short and faint, which prevented them from measuring a reliable parallax signal.”Both events were too short and too faint to measure a reliable parallax signal and hence the lens mass. We therefore used a Bayesian analysis to estimate masses of both planets,” the paper reads.The team noted that in order to uncover more properties of the two newly discovered planetary systems, follow-up high-resolution imaging observations should be conducted in the future. In particular, the Near InfRared Camera (NIRCam) on the James Webb Space Telescope (JWST) that will be launched into space in late 2018, could reveal important insights about these new Saturn-mass exoworlds.

The newly found planets are estimated to be as massive as Saturn and are orbiting M dwarfs beyond the snow line. The findings were presented May 2 in a paper published online on the arXiv pre-print server. More information: OGLE-2013-BLG-0132Lb and OGLE-2013-BLG-1721Lb: Two Saturn-mass Planets Discovered around M-dwarfs, arXiv:1705.01058 [astro-ph.EP] arxiv.org/abs/1705.01058AbstractWe present the discovery of two planetary systems consisting of a Saturn-mass planet orbiting an M-dwarf, which were detected in faint microlensing events OGLE-2013-BLG-0132 and OGLE-2013-BLG-1721. The planetary anomalies were covered with high cadence by OGLE and MOA photometric surveys. The light curve modeling indicates that planet-host mass ratios are (5.15±0.28)×10−4 and (13.18±0.72)×10−4, respectively. Both events were too short and too faint to measure a reliable parallax signal and hence the lens mass. We therefore used a Bayesian analysis to estimate masses of both planets: 0.29+0.16−0.13 MJup (OGLE-2013-BLG-0132Lb) and 0.64+0.35−0.31 MJup (OGLE-2013-BLG-1721Lb). Thanks to a high relative proper motion, OGLE-2013-BLG-0132 is a promising candidate for the high-resolution imaging follow-up. Both planets belong to an increasing sample of sub-Jupiter-mass planets orbiting M-dwarfs beyond the snow line. © 2017 Phys.org Massive exoplanet discovered using gravitational microlensing method
Implementing the single-molecule DNA navigator. a) Schematic illustration of the PSEC system. An acyclic connected graph (i.e. a tree) is constructed on a rectangular DNA origami substrate of 100 x 70 nm^2. T1 and T2 are two types of fuels driving the PSEC on the tree. Initiator I was used to trigger the initiation of the PSEC from the entrance vertex ENT. b) propagation mechanism of the PSEC system. Initiator I recognizes and opens the T1ent hairpin at vertex ENT. The opened hairpin then captures and opens a T2 hairpin from the environment to start the cascade. c) A straight line paved by PSEC and visualized with DNA-PAINT. d) Four paved digits of “2017” imaged using atomic force microscopy (AFM). The T1 hairpins at the corner points were modified to prevent unwanted spans. The arrows indicate the direction of propagation.

The platform explored all possible paths through a tree graph designed on an origami structure as a simply connected maze without cyclic paths. Such DNA origami structures are information-bearing nanostructures by nature with well-defined nanoscale geometry. The maze could be explored by proximal strand exchange cascade (PSEC) based on hybridization chain reactions. The researchers demonstrated that a system with a large number of single-molecule DNA navigators could collectively conduct parallel depth-first search (PDFS) on the tree to efficiently perform maze solving within 2-D origami. Initially the researchers conducted studies to test the PSEC design.

A Logic-Gated Nanorobot for Targeted Transport of Molecular Payloads, Science (2012). DOI: 10.1126/science.1214081 Kinetics of the process were investigated at the single-molecule level in the study using time-resolved total internal reflection fluorescence microscopy (TIRF) in a setup with a prescribed starting point (P0) and five intermediate steps (P1-P5). Fluorescence in the setup was quenched using fluorescence resonance energy transfer (FRET), and the cascade was observed in real time by recording fluorescence signals continuously. The average speed of propagation was recorded to be 2.46 nm per minute, propagation across the straight line (54.4 nm) took approximately 22 minutes. The scientists then constructed the main model maze with 10 vertices that included an entrance vertex A and an exit vertex J, three junctions (B, D, E) an intermediate vertex (I) and four dead ends (C, F, G, H). Each path of the maze that was equivalent to a tree with 10 vertices was investigated using DNA investigators starting at root A. The PSEC reactions produced a mixture of various paths on the maze, confirmed with AFM. Each individual PSEC could progress on one of the five possible paths. Statistical analysis of the length distribution showed that the measured paths coincided well with the values predicted. To prevent the navigators from propagating through a wrong path with dead ends, the scientists designed a streptavidin-biotin tag-based method to selectively eliminate inaccurate path navigation. Only the correct path (PABDIJ) was followed in the maze therefore. The computational context used in the study allowed exploration of paths through tree graphs defined on the origami. The autonomous path explored by the DNA navigators proceeded unidirectionally and irreversibly, turning at junctions and corners on the origami platform as they were designed to. The design enabled parallel depth first search (PDFS) allowing each DNA navigator to individually explore any one of the paths through the given graph at a defined speed, greater than that previously achieved. The main advantage of the described biomolecular computer schemes in comparison to conventional electronic computing is they can be interfaced directly with biologically relevant processes. As a result, the scientists envision translational biomedical sensing and decision-making platforms with DNA origami and single-molecule diagnostics using decision trees. Future applications will also include simple sensors or those coupled to a molecular actuator to trigger downstream molecular cascades. , Nature Nanotechnology Pathfinding operations with DNA navigators make use of a localized strand exchange cascade process initiated at a unique trigger site on the origami platform. Automatic progression along paths is enabled by DNA hairpins containing a universal traversal sequence. By design, each single-molecule navigator can autonomously explore any of the possible paths through a 10-vertex rooted tree constructed in the study. The mazes were equivalent to a tree with an entrance at the root and an exit through one of the leaves. The study conducted by Jie Chao and co-workers resulted in exploring all paths taken by the DNA navigators to extract a specific solution path that connected a given pair of start and end vertices in the maze. As a result, the solution path was laid plainly on the origami platform and illustrated using single-molecule imaging. The approach is now published in Nature Materials, detailing the realization of molecular materials with embedded biomolecular computational functions to operate at the level of the single-molecule with potential to engineer intelligent nanorobots for future applications in industry and medicine.Sophisticated molecular tools were used in the past to create molecular machines that convert chemical, photonic or electric energy into rotary or linear movements at the nanoscale. For instance, Brownian motion at the nanoscale can be controllably converted into directed movements within DNA-based nanomachines using DNA hybridization reactions. Such DNA-based machines operate autonomously by following an embedded ‘molecular program’ pre-designed as a cascade reaction manually triggered via an external stimulus for each step of the operation. The focus of the field has progressively shifted to actualize DNA-based logic circuits using aptamers and DNAzymes to design molecular logic gates. For example, in 2006, Stojanovic and co-workers integrated more than 100 DNA logic gates to engineer an automation calledMAYA-II to play a game of Tic-Tac-Toe. Preceding studies demonstrated an enzyme free computing system based on hybridization chain reactions (HCR) to create logic-gates and logic circuits for more robust and efficient performance than the original systems.

Exit vertex J is labelled with biotin to enable differentiation between the correct and wrong paths.

All wrong paths could be captured and removed by the Streptavidin-modified magmatic beads therefore. b) Details of the release of biotin modification at the exit J by the PSEC. c) AFM characterization of the correct solution after selection.

Explore further The proximal strand exchange cascade (PSEC) system (working principle of the DNA navigator) was facilitated on a rectangular origami substrate made of three components, which included the physical implementation of a tree graph, full strands and an initiator strand. Vacant areas without staple extensions corresponded to walls in the maze, preventing propagation of the strand exchange cascade. The entrance and exit were defined and denoted as ENT and EXIT respectively. In the second component, two types of DNA hairpins, T1 and T2, were used as fuels to drive the PSEC on the tree graph. The two hairpins coexisted metastably in solution to hybridize and fuel the PSEC process with free energy . By design, information only propagated through the network in the presence of an initiator (Initiator I). Upon addition of initiator I, PSEC was conducted and observed using atomic force microscopy (AFM). To visualize an established formation, the scientists enabled DNA-navigator-based formation of the number 2017 as a proof-of-principle. Another technique known as DNA-PAINT was employed as a single-molecule, super-resolution imaging technique to reveal molecular features at the nanoscale to further substantiate the PSEC-based path paving process. The on-origami PSEC was highly specific, without intra- or inter-origami crosstalk. The field of intelligent nanorobotics is based on the great promise of molecular devices with information processing capabilities. In a new study that supports the trend of DNA-based information carriers, scientists have engineered a DNA navigator system that can perform single-molecule, parallel, depth-first search operations on a two-dimensional origami platform.

Kolkata: Murshidabad district police have nabbed two persons and seized Fake Indian Currency Notes (FICN) worth Rs 7 lakh from Farakka.According to police, on Thursday night sleuths got a tip-off that a good number of FICN denominations will be smuggled through Farakka. After a while police came to know from sources that two persons from south India whose whereabouts seemed suspicious were staying in a hotel near New Farakka crossing. Based on the information, on the wee hours of Friday, police raided the room number 33 of the hotel and detained two residents of Chittoor in Andhra Pradesh. During search sleuths found 350 FICN of Rs 2000 denomination. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseImmediately, the duo identified as Raghunand Naidu and Rajesh Dewala was arrested. Later, during interrogation they said that they were acting as a carrier of FICN. A person from Baishnabnagar in Malda had delivered the FICNs to them on Thursday. They were about to leave for Chittoor on Saturday. They also confessed that previously they tried to get hold of FICN but failed to get right contact. Sleuths suspect that a racket in Andhra Pradesh is trying to smuggle in FICN there. The Superintendent of Police (SP) of Murshidabad, Sri Mukesh said: “The rate of FICN is Rs 1 lakh for FICN worth Rs 2 lakh. We are trying to identify the person who came from Malda to deliver the FICNs.” Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataAccording to police, last year Murshidabad District Police had nabbed 84 persons and seized FICN worth Rs 1 crore 28 lakh. This year till Friday, 10 persons have been arrested and approximately Rs 10.28 lakh have been seized. Malda for long has a prominent hub for counterfeit currency trade. According to an estimate by Bengal CID, this year, various security agencies have seized counterfeit currencies worth Rs 1.75 crore from across the country and every seizure had the familiar Malda link.
