(Phys.org) —Talk about big ideas. Not satisfied to rest on laurels of having brought forth the open source browser Firefox, Mozilla—defined by some as a global project, by others as one of the key open-source movements, is thinking big, really big, about changing the world of scientists. This month Mozilla announced that it is launching the Mozilla Science Lab, with support from the Alfred Sloan Foundation. According to a blog post by Foundation executive director, Marc Surman, Mozilla is creating a Science Lab for researchers around the world. The idea is to enable researchers to more easily (1) be in a virtual place where they share ideas, tools and best practices for using next-generation web solutions to solve problems in science, and (2) to make this an exploration as to how to make research faster, more agile and collaborative. But, here’s the problem. Mozilla is ready to get started, but are scientists ready to get started? Surman wrote, “Scientists created the web—but the open web still hasn’t transformed scientific practice to the same extent we’ve seen in other areas like media, education and business. For all of the incredible discoveries of the last century, science is still largely rooted in the ‘analog’ age.”This is 2013 and the style of scientific work is in a time warp, say critics who wish there was a different type of work environment. The researcher may conduct research and submit findings in the form of a paper to a peer-review journal; upon publication the world will see what was achieved. While developers easily share tips and observations in online community groups that push projects and solutions ahead, scientists elsewhere may feel the pressure of sticking to a publish-the-paper path and hang back from working in a global collaborative environment. The Lab’s team is ready for the challenge. “In scientific research, we’re dealing with special circumstances, trying to innovate upon hundreds of years of entrenched norms and practices, broken incentive structures and gaps in training that are dramatically slowing down the system, keeping us from making the steps forward needed to better society.”A basic step forward will be providing digital literacy for scientists. Sharing, re-using and producing research on the web involves computer skills they may not yet have. Software Carpentry will be a member of the lab team for this purpose. According to the announcement, “As part of the Mozilla Science Lab, Software Carpentry will explore what ‘digital literacy’ means for scientific researchers and how these digital skills can further aid their work.” Kaitlin Thaney is the director of the Mozilla Science Lab.Software Carpentry, a volunteer organization supported by the Alfred P. Sloan Foundation and the Mozilla Foundation, teaches basic computing skills. They operate through two-day boot camps for scientists. Organizations have supported their efforts since they ran their first class at Los Alamos National Laboratory in 1998. Learners are typically graduate students in science, engineering, and medicine who have written a few lines of code either on their own or for a class as undergrads, but are not familiar with practices in scientific computing such as version control or unit testing.) With or without the Mozilla effort, however, there is a sense that scientists are moving toward a collaborative model; at least some scientists believe that it is the obvious way of the future in an Internet-connected world. ResearchGate, the networking site for scientists, is given as an example. ResearchGate began in 2008, by scientists for scientists. Its founders, physicians and a computer scientist, have seen its membership grow considerably. ResearchGate is used by researchers who can present their work, share publications, connect with specialists in their field, ask questions, and get answers about research issues.center_img © 2013 Phys.org Taiwan’s Hon Hai in tie-up with Mozilla More information: www.researchgate.net/ www.nytimes.com/2012/01/17/sci … ?pagewanted=all&_r=0wiki.mozilla.org/ScienceLablast_img read more

first_img Citation: Linking antibiotic to antibody found able to kill MRSA hiding in mice cells (2015, November 5) retrieved 18 August 2019 from https://phys.org/news/2015-11-linking-antibiotic-antibody-mrsa-mice.html Prior research has found that one of the ways that bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) become resistant to drugs meant to kill them, is by hiding out in host cells, where antibiotics cannot find them. Many in the field believe this is why some bacterial infections return so quickly after antibiotics are stopped. In this new effort, the researchers developed a way to cause a common antibiotic to bind to an antibody until it gets inside a host cell harboring a certain type of bacteria—then, the bond is broken and the antibiotic kills the bacteria.More specifically, they created an anti-S. aureus antibody that grabs onto one type of sugar found on the exterior part of the bacteria. Next, they attached an antibiotic called rifalogue via a linker molecule to cysteines on the antibody. The result was the creation of antibody-antibiotic conjugates, or AACs. Once they make their way inside a certain host cell, the linker molecule is removed releasing the antibiotic to do its job.The team reports that injecting the AACs they created into infected mice was far more effective at completely wiping out an infection than standard treatments used today. Hardt notes that if the technique proves to be successful in humans, the use of AACs could also mean less development of resistance in bacterial strains because the technique allows for focusing on just one type of bacteria.

Novel antibody–antibiotic conjugate eliminates intracellular S. aureus, Nature (2015). DOI: 10.1038/nature16057AbstractStaphylococcus aureus is considered to be an extracellular pathogen. However, survival of S. aureus within host cells may provide a reservoir relatively protected from antibiotics, thus enabling long-term colonization of the host and explaining clinical failures and relapses after antibiotic therapy. Here we confirm that intracellular reservoirs of S. aureus in mice comprise a virulent subset of bacteria that can establish infection even in the presence of vancomycin, and we introduce a novel therapeutic that effectively kills intracellular S. aureus. This antibody–antibiotic conjugate consists of an anti-S. aureus antibody conjugated to a highly efficacious antibiotic that is activated only after it is released in the proteolytic environment of the phagolysosome. The antibody–antibiotic conjugate is superior to vancomycin for treatment of bacteraemia and provides direct evidence that intracellular S. aureus represents an important component of invasive infections. (Phys.org)—A large team of researchers from several institutions in the U.S. and one in Denmark, working for Genentech, has found that binding an antibiotic to an antibody can be more effective in treating bacterial infections than current methods. In their paper published in the journal Nature, the group describes how their procedure works and the results they found when testing it in mice. Wolf-Dietrich Hardt with the Institute of Microbiology, ETH in Switzerland offers a News & Views piece on the work done by the team and suggests that if the technique proves to work the same way in humans, it could lead to the development of drugs meant to kill infections that are less harmful to good bacteria in the body.center_img Journal information: Nature © 2015 Phys.org Scanning electron micrograph of S. aureus; false color added.

The content is provided for information purposes only. The astronomers, led by Ignazio Pillitteri of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, have used the European Space Agency’s (ESA) XMM-Newton spacecraft to conduct X-ray observations of two regions near Kappa Ori containing young stellar objects (YSO). They detected a total of 121 interesting X-ray sources that appear to be stars with disks, protostars and candidate class III stars. They determined that these YSOs form a distinct star-forming shell between 16 and 26 light years in diameter. Very young stars are very powerful emitters of X-rays. Thus, X-rays are often used to discover young stars embedded in gas and clouds, where optical and infrared observations fail to deliver detailed information. This is because X-rays can penetrate these clouds much better than optical photons.Pillitteri and his colleagues used the X-ray fluxes to compare the emission from stars near Kappa Ori to that in the filamentary dark cloud complex named L1641, observed with the Survey of Orion A with XMM-Newton and Spitzer (SOXS). It was surprising and challenging to discover that there are groups of young stars near Kappa Ori that are significantly more luminous than their siblings in L1641.”In general, the study of the Orion cloud was challenging because recent observations have demonstrated that this ‘nursery’ of stars has a complex structure made of nested bubbles produced by the interaction between the cloud and supernovae explosion or winds from massive stars. My collaborators and I have started to study the Orion A nebula and L1641 in X-rays with SOXS. The research regarding Kappa Ori is a follow-up of that study,” Pillitteri told Phys.org.According to the authors of the paper, the ring of stars with disks is visible in mid-infrared data, as well as in far-infrared and CO line maps. However, the ring is in projection toward the tail of Orion A and the more distant Mon R2 star-forming region; thus, it is not easy to disentangle the single structures along the same line of sight. The existence of this ring yields important information about star formation processes. It supports a scenario in which stellar winds from a massive star at the center of a gas cloud can sweep and compress the gas around it. The gas can then collapse and give birth to stars. Of course, further observations are needed to study this scenario and also to get more insights on these interesting young stellar objects.”There is at least one other field that we want to study, containing a group of young stars with disks. We want to conduct follow-up observations with optical spectroscopy that can be useful to determine photospheric temperatures, gravity, chemical composition and the age of these stars. We also wait for GAIA (Global Astrometric Interferometer for Astrophysics) spacecraft data release that would benefit to study of the whole Orion complex,” Pillitteri concluded.If confirmed by GAIA or other future measurements, this ring will be one of several nested shells found in the Orion-Eridanus superbubble. It could therefore be a great example of star-formation mechanisms where massive stars sweep up the gas and dust in the hot interiors of superbubbles to form shells of cold, star forming gas. (Phys.org)—Astronomers have spotted a star-forming ring around a distant star Kappa Ori, located at the south-eastern corner of the constellation of Orion. The star, also known as Saiph, is a supergiant with a mass of approximately 15 solar masses about 650 light years from Earth. According to the scientists, the newly-detected ring contains several groups of stars. The results were published in a paper on Mar. 1 in the arXiv journal. Far-IR Planck 857 GHz (left panel), mid-IR WISE 12µm (central panel, image from Meisner & Finkbeiner 2014) and velocity integrated CO image (right panel, from CfA CO survey of Dame et al. 2001) around Kappa Ori.

More than meets the eye: Delta Orionis in Orion’s belt Explore further More information: A star forming ring around Kappa Ori 250 pc from the Sun, arXiv:1603.00205 [astro-ph.SR] arxiv.org/abs/1603.00205AbstractX-rays are a powerful probe of activity in early stages of star formation. They allow us to identify young stars even after they have lost the IR signatures of circumstellar disks and provide constraints on their distance. Here we report on XMM-Newton observations which detect 121 young stellar objects (YSOs) in two fields between L1641S and κ Ori. These observations extend the Survey of Orion A with XMM and Spitzer (SOXS). The YSOs are contained in a ring of gas and dust apparent at millimeter wavelengths, and in far-IR and near-IR surveys. The X-ray luminosity function of the young stellar objects detected in the two fields indicates a distance of 250-280 pc, much closer than the Orion A cloud and similar to distance estimates of κ Ori. We propose that the ring is a 5-8 pc diameter shell that has been swept up by κ Ori. This ring contains several groups of stars detected by Spitzer and WISE including one surrounding the Herbig Ae/Be stars V1818 Ori. In this interpretation, the κ Ori ring is one of several shells swept up by massive stars within the Orion Eridanus Superbubble, and is unrelated to the southern portion of Orion A / L1641 S.

(Phys.org)—A team of researchers with the University of California and Stanford University has found that applying “empirical dynamic modeling” techniques to heat and humidity readings over a period of several years revealed some of the factors that cause flu outbreaks to occur. In their paper published in Proceedings of the National Academy of Sciences, the group describes the mathematical modeling techniques they used and what it revealed about the spread of the flu.

Credit: CDC Most everyone in places like Europe and the U.S. knows that winter is cold and flu season—but not so clear is when flu is more likely to spread in tropical regions, though scientists have long suspected it is tied to warmer or rainy periods. In this new effort, the researchers applied mathematical models to the problem in an attempt to provide more concrete answers.The researchers used what they describe as an “empirical dynamic modeling framework” to analyze flu outbreak patterns—such time-series models have proven useful in detecting causality in nonlinear systems before (e.g. making connections in anchovy and sardine populations). As possible factors, they used heat and absolute humidity (the actual amount of water in the air), relative humidity (the amount of water in the air relative to temperature) and precipitation amounts over the course of 18 years of flu outbreak data. They report that their models indicate humidity is the strongest environmental factor influencing the spread of the flu, though temperature also plays a part. Interestingly, they found that at temperatures of approximately 70 to 75 degrees, the impact of humidity switches—below that number, drier air supports more flu transmission, but above that mark, more humid air means more flu transmission. The models, the team claims, parallel real-world observations—in places like North America, when the temperature dips below the switch point and humidity levels drop, the flu season starts, but in tropical areas, flu “seasons” typically occur during times when the humidity rises. The results also match with prior research showing that the flu virus tends to swell and burst when exposed to a cold, humid environment and dries up when things get hot and dry.These findings, the team suggests, means that simply adding humidifiers to homes in temperate climates and running them during the cold months might actually slow the spread of an outbreak.last_img read more

first_imgDelhi has no dearth of great places to eat, but here’s a lowdown. Seven restaurants have been picked out for Restaurant Week India and foodies can be rest assured that they will not be disappointed. Scheduled for 23 September to 2 October, Restaurant Week India (RWI) is on its seventh round in the country. Restaurant Week originated in New York in 1992 and is now held in various cities in Europe, South America and even South East Asia.This year’s run of RWI includes Dakshin, Diva, Diva Kitsch, Sevilla, Pan Asian, Le Riviera and Prego. These restaurants will be offering a three-course prix fixe menu at Rs 1000 for lunch and Rs 1200 for dinner. Dakshin was our pick for the preview for RWI. The restaurant at Sheraton has enough awards in its kitty to make a statement.  Also Read – ‘Playing Jojo was emotionally exhausting’Known for cuisines from the south of the country, Dakshin dishes out a mean fare with some excellently done dishes. The pan fried fish is one of the dishes which gets all our votes. The simple but delectable vegetable stew that goes best with appams is a must try. Then of course there are the soft Malabar paranthas which go very well with the spicier non vegetarian dishes. We also tried the spicy dry lamb which the restaurant recommended as one of their top picks.  Also Read – Leslie doing new comedy special with NetflixThe best part of the Dakshin experience was the open kitchen where appams are made right in front of you. The authentic south Indian coffee is also a must in Dakshin. And yes, the completely awesome serving of papads that Dakshin along with some incredible chutneys. It is almost impossible to keep your hands off them even after the food arrives. Keep up with us as RWI starts on good and proper by end of this month and as a reminder – general reservations for RWI starts online from 18 September. Go book your tables.last_img read more

About the festival, he said it is very important to realise the importance of roots. “As the force of globalisation is really picking up and there is the dangerous phenomenon which one can see about one gradually losing his identity, your roots have to be very strong,” he said. West Bengal Minister of State for Cultural Affairs Indranil Sen, who also present on the occasion, said his department will extend all cooperation to the organisers of the ‘Sahaj Parav’ festival – Lopamudra Foundation and Dohar – in organising folk music festivals in 341 blocks, if they wanted it. Sen said 1,94,000 folk artistes were now getting monthly stipend from the state government, as part of the initiative to promote folk music. “Unlike the previous regime, we don’t bring the folk musicians to hold a big rally once in a year and then forget all about them. We are committed in improving their economic conditions,” he added.last_img read more
