Antarctic bdelloid rotifers: diversity, endemism and evolution

first_imgAntarctica is an isolated continent whose conditions challenge the survival of living organisms. High levels of endemism are now known in many Antarctic organisms, including algae, tardigrades, nematodes and microarthropods. Bdelloid rotifers are a key, widespread and abundant group of Antarctic microscopic invertebrates. However, their diversity, regional distribution and endemism have received little attention until recently. We provide the first authoritative review on Antarctic Bdelloidea, based on published data and new collections. Our analysis reveals the extreme levels of bdelloid endemism in Antarctica. Sixty-six bdelloid morphospecies are now confirmed from the continent, and 83–91 putative species are identified using molecular approaches (depending on the delimitation method used). Twelve previously unknown species are described based on both morphology and molecular analyses. Molecular analyses indicate that only two putative species found in Antarctica proved to be truly cosmopolitan. The level of endemism based on the available data set (95%) is higher than that in any other continent, with many bdelloid species occurring only in maritime or continental Antarctica. These findings are consistent with the long-term presence of Bdelloidea in Antarctica, with their considerable isolation facilitating intraregional radiation, providing further evidence that does not support the microbial global ubiquity hypothesis that “everything is everywhere.”last_img read more

Atmospheric ice-nucleating particles in the dusty tropical Atlantic

first_imgDesert dust is one of the most important atmospheric ice‐nucleating aerosol species around the globe. However, there have been very few measurements of ice‐nucleating particle (INP) concentrations in dusty air close to desert sources. In this study we report the concentration of INPs in dust laden air over the tropical Atlantic within a few days’ transport of one of the world’s most important atmospheric sources of desert dust, the Sahara. These measurements were performed as part of the Ice in Clouds Experiment‐Dust campaign based in Cape Verde, during August 2015. INP concentrations active in the immersion mode, determined using a droplet‐on‐filter technique, ranged from around 102 m−3 at −12°C to around 105 m−3 at −23°C. There is about 2 orders of magnitude variability in INP concentration for a particular temperature, which is determined largely by the variability in atmospheric dust loading. These measurements were made at altitudes from 30 to 3,500 m in air containing a range of dust loadings. The ice active site density (ns) for desert dust dominated aerosol derived from our measurements agrees with several laboratory‐based parameterizations for ice nucleation by desert dust within 1 to 2 orders of magnitude. The small variability in ns values determined from our measurements (within about 1 order of magnitude) is striking given that the back trajectory analysis suggests that the sources of dust were geographically diverse. This is consistent with previous work, which indicates that desert dust’s ice‐nucleating activity is only weakly dependent on source.last_img read more

U.S. Manufacturing Hits The Road, Alive, Well and Kicking!

first_imgThe evolution of manufacturingI was honored to represent Dell EMC at this kick-off event, which was hosted by Emerson Chairman and CEO David Farr, a good friend and the new chair of the NAM Board. However, some of you may be wondering why start a manufacturing tour in Central Texas? When you think of the Austin area – also known as the Silicon Hills – the image of a typical, middle-America factory town doesn’t exactly spring to mind.And yet, it’s right at the heart of an evolution in manufacturing. There is a digital transformation underway in this industry and there are hundreds of businesses in Central Texas – from Emerson and Dell EMC to software companies and small start-ups – who are helping to usher in a new era in modern manufacturing. Austin has numerous examples of companies working together to modernize manufacturing in the U.S. but the same exciting story is being emulated throughout the country.Painting a picture of modern manufacturingSo, what does modern manufacturing look like? Manufacturing is learning from other industries that have been successful in adopting new approaches to technology to gain a competitive edge. Instead of resisting technology, manufacturing is now embracing ways to do things faster, smarter and better. Today’s factories now have the IT tools to collect, analyze and act on data in real time to optimize their operations, lower costs, increase throughput and gain a competitive edge.Let me give you some practical examples. Energy producers are reducing downtime and improving profitability by remotely monitoring critical equipment (think of a refinery or an off-shore oil rig) with sensors, edge gateways and sophisticated cloud-hosted analytics tools. This reduces potential employee exposure to hazardous conditions while helping the company to leverage expertise wherever it may exist. In other industries, such as automobile manufacturing, factories are using technology to do real-time testing and quality control during the assembly process to make adjustments and prevent potential problems before they occur.Lines blurring between IT and factory systemsSo, as you can see, it’s no longer a case of information technology (IT) being confined to the data center and the office with operational technology (OT) (factory systems) on the manufacturing floor. We’re now seeing the lines blur between IT and OT with embedded devices and sensors connecting and talking to previously siloed systems within a manufacturing facility. We’re experiencing how the Industrial Internet of Things – IIoT – can help customers get a more accurate and holistic picture of their performance.Partners who can add valueOf course, harnessing all this data and connecting all of the parts and players requires a complex ecosystem of experienced technology partners and a workforce with the skills needed to succeed in today’s knowledge-based economy. This is where companies like Emerson and Dell EMC can add expertise and value. Dell EMC has enjoyed a long and fruitful partnership with Emerson over the years, from developing data center standards and collaborating on the launch of multiple OEM products all the way through to the solutions that power automation processes on the factory floor. Today, we are working together to help manufacturing customers harness the power of the Internet of Things.Using technology to make manufacturing more competitiveI believe that modern manufacturing has a huge role to play in the global economy and can continue to positively impact the lives of millions of American families. However, we need to make manufacturing more competitive. We need to use technology to reinvent processes and strengthen the industry’s ability to hire workers with the skills needed in this digital age. We can absolutely enable new jobs if we have technology and manufacturing working together in tandem. Above all else, manufacturing needs to attract our best and brightest young people. The industry offers a lifelong, rewarding career with the chance to design and build a new high-tech, high-touch future. It’s exciting stuff!Global competition and increasing customer demands are certainly changing the face of manufacturing as we know it, but I think we’re all ready to embrace the challenge head-on. Dell EMC is proud to contribute to the digital transformation of this vital industry. Join the conversation and be part of the solution. I would love to hear your views and am happy to answer your questions. I also invite you to check out the NAM’s “Creators Wanted” video, which features two Dell EMC team members and highlights the many facets of a career in modern manufacturing.Keep in touch by following Dell EMC OEM or IoT on LinkedIn. While traditional manufacturing in the U.S. has certainly had to contend with ups and downs over the last few decades, the good news is that the modern industry is alive, well and kicking. In fact, right now, it is driving a huge innovation revolution across the U.S. This was the strong, take-away message to policy makers and elected officials from the National Association of Manufacturers (NAM) at the start of its annual tour last week in Round Rock, Texas.last_img read more

Snite Museum exhibit focuses on African experience

first_imgThe Snite Museum of Art’s new fall exhibit stretches through numerous rooms with large paintings, sculptures and even electric metal signs. Biographies of the many artists adorn the walls alongside their respective artwork, giving more of a story to each piece. Each work of art tells some kind of rich and brilliant story, typically etched into the history of the black experience.This exhibit, entitled “Solidary and Solitary: the Joyner/Giuffrida Collection,” was brought to the Snite Museum by curators Christopher Bedford and Katy Siegel. It celebrates black artists and will be up for viewing in the museum until December 15.According to a press release from the Snite Museum, this is a historical exhibition that offers a new perspective on issues people of African descent have faced throughout history.“This will be the first large-scale public exhibition to bring together a vital lineage of visionary black artists,” the press release said. “This exhibition offers a new perspective on the critical contribution black artists have made to the evolution of visual art from the 1940s through the present day.”Gina Costa, marketing and public relations manager for the Snite Museum, said this exhibition has been on display around the country and the former director of the Snite, Charles Loving, worked with the Baltimore Museum of Art to get “Solidary and Solitary” to Notre Dame. However, because of space limitations, the Snite Museum can only show part of the exhibit.“It was a great opportunity for the museum to display an exhibition that offers a new perspective of the critical contribution of black artists,” Costa said. “These works reveal how African artists have used abstraction as a visual vocabulary to talk about the issue of being black, social struggles and the international African diaspora.”The exhibit displays works from a wide variety of artists using several different mediums. Some include oil canvas paintings, re-draped canvas, sculptures, found fabric and more.Costa said the most notable artists are Sam Gilliam, Norman Lewis and Kevin Beasley.Quoting the Snite press release, Costa said “the entire collection is really of an unparalleled level and shows the power of abstract art as a profound political choice rather than just a stylistic preference for generations of artists.”According to the press release, “[the exhibit] will reveal a rich and complex history woven from the threads of artistic debates about how to embody blackness, social struggle and change.”Museum visitors will have the opportunity to meet the curators, Bedford and Siegel, during a free public reception with refreshments on the evening of Oct. 26.Costa also said she wanted to emphasize the accessibility of the Snite Museum to Notre Dame students.“Students often don’t know that the museum is free and open to the public. It’s their museum.”Editor‘s note: A previous version of this story incorrectly stated the role of Christopher Bedford and Katy Siegel in the Snite Museum’s new exhibition. Bedford and Siegel are the curators of the exhibition. The Observer regrets this error.Tags: Snite Museum, Snite Museum of Art, Solidary and Solitarylast_img read more
