Brines in seepage channels as eluants for subsurface relict biomolecules on Mars?

first_imgWater, vital for life, not only maintains the integrity of structural and metabolic biomolecules, it also transports them in solution or colloidal suspension. Any flow of water through a dormant or fossilized microbial community elutes molecules that are potentially recognizable as biomarkers. We hypothesize that the surface seepage channels emanating from crater walls and cliffs in Mars Orbiter Camera images result from fluvial erosion of the regolith as low-temperature hypersaline brines. We propose that, if such flows passed through extensive subsurface catchments containing buried and fossilized remains of microbial communities from the wet Hesperian period of early Mars (~3.5 Ga ago), they would have eluted and concentrated relict biomolecules and delivered them to the surface. Life-supporting low-temperature hypersaline brines in Antarctic desert habitats provide a terrestrial analog for such a scenario. As in the Antarctic, salts would likely have accumulated in water-filled depressions on Mars by seasonal influx and evaporation. Liquid water in the Antarctic cold desert analogs occurs at -80°C in the interstices of shallow hypersaline soils and at -50°C in salt-saturated ponds. Similarly, hypersaline brines on Mars could have freezing points depressed below -50°C. The presence of hypersaline brines on Mars would have extended the amount of time during which life might have evolved. Phototrophic communities are especially important for the search for life because the distinctive structures and longevity of their pigments make excellent biomarkers. The surface seepage channels are therefore not only of geomorphological significance, but also provide potential repositories for biomolecules that could be accessed by landers.last_img read more

Pall to Supply Freshwater Generator Systems for RN’s Type 45 Destroyer

first_imgBack to overview,Home naval-today Pall to Supply Freshwater Generator Systems for RN’s Type 45 Destroyer View post tag: News by topic View post tag: Type August 29, 2012 View post tag: Freshwater Industry news Pall Corporation announced that it has been selected by BAE Systems to supply freshwater generator systems for the UK Royal Navy’s Type 45 Destroyer. The Type 45 ships are designed and built by BAE Systems and are the most advanced warships ever produced in the UK. The Pall Integrated Membrane System (IMS)/ freshwater generator is designed to transform any type of sea water into drinkable water. Sea trials have demonstrated that it works efficiently with the high contamination levels found in some coastal waters.The fully automatic, cleanable IMS helps reduce maintenance tasks and has a lower cost of ownership compared to conventional water treatment systems.Management Team said, “The Type 45 is the largest and most powerful Air Defence Destroyer ever built for the Royal Navy. It is a versatile platform capable of contributing to worldwide maritime and joint operations in multi threat environments. It is essential that these ships can produce fresh water wherever they are operating; we were very pleased with the performance of Pall’s IMS for delivering fresh water supplies during the ship’s deployment.”“In addition to implementation with UK’s Royal Navy ships, the IMS has operated successfully at many other military, commercial, and disaster relief sites around the world,” commented Vince Northfield, president of Pall Aerospace.The IMS freshwater generator integrates hollow fiber microfiltration (MF) and reverse osmosis (RO) modules. It removes suspended solids, e.g., bacteria and viruses, dissolved components (such as salts), and other contaminants from sea water. The system significantly reduces the requirement to store spare filter cartridges and can be used to boost water production on a permanent or temporary basis.Pall is a leading global supplier of permanent and mobile water filtration solutions for municipal and industrial water, emergency relief applications, as well as the military.[mappress]Naval Today Staff, August 29, 2012; Image: Pall View post tag: Pall Share this article View post tag: Supplycenter_img Pall to Supply Freshwater Generator Systems for RN’s Type 45 Destroyer View post tag: Navy View post tag: 45 View post tag: RN View post tag: Generator View post tag: Destroyer View post tag: Systems View post tag: Navallast_img read more

Oxford scientists see IVF success soar

first_imgThe collaboration of Oxford University doctors and the Colorado Centre for Reproductive Medicine could see success rates of IVF soar due to developments in screening embryos.The new process, comparative genomic hybridisation (CGH), allows doctors to monitor all the chromosomes in the developing embryo. It is believed that a common cause of miscarriage is an abnormal number of chromosomes.This new method has the potential to double impregnation rates in women who would otherwise have problems conceiving, while it is estimated that the live birth rate will rise from a predicted rate of 60% to 78%.Dr Dagan Wells, of Oxford University, described the increased pregnancy rates as “absolutely phenomenal.”last_img read more

Eddie Roberts Honors Grant Green In Denver With Special “Green Is Beautiful” Run [Photos]

first_imgLoad remaining images Load remaining images This weekend, resident guitarist extraordinaire of The New Mastersounds, Mr. Eddie Roberts, honored jazz guitarist Grant Green with his tribute to the pioneering musician dubbed “Green Is Beautiful” after Green’s 1970 release by the same name. Roberts invited other friends to join him in celebrating Green’s work, tapping Alan Evans (Soulive, Karl Denson’s Tiny Universe) on drums, Chris Spies on keys, Alex Scott on bass, and Nick Gerlach (Turbo Suit) on sax to round out the crew, with Thievery Corporation’s Jeff Franca sitting in on bongos following his own performance at the Fillmore Auditorium on Friday night. On the heels of 4/20, the name of the tribute might have seemed tongue-in-cheek to some, but together, the collection of enviable musicians went above and beyond in showcasing the beauty of Grant Green’s music.Roberts’ “Green Is Beautiful” tribute first debuted in September of last year as part of the line-up for Bear Creek Bayou in New Orleans. After its success in the fall, Roberts brought the project home to Denver and, in addition to rotating in new musicians to share in commemorating the frequently unsung jazz guitarist of Blue Note Records, expanded it to two nights, hitting Cervantes’ Other Side this past Friday and Ophelia’s Electric Soapbox on Saturday. In seeing the group perform, it’s immediately apparent that this is a passion project for Roberts. His love of Grant and his work is undeniable, shining through both in his meticulous playing and stage banter. It’s charming to see the acclaimed guitarist so excited to share Grant’s music with others, readily dropping bits of knowledge and instructing listeners to carefully pay attention to specific elements of certain songs.For Friday’s performance at Cervantes’ Other Side, the setlist primarily focused on Green’s work from the late 60’s and 70’s during which Green’s style was reinvented with a more funk-inflected sound, all of which are perfectly suited for an ensemble featuring members of the New Mastersounds and Soulive. From the first songs, “Upshot” off Green’s 1969 release Carryin’ On and “The Selma March” off 1965’s His Majesty, King Funk, the band was in proper form, easily settling into the slinky, laid-back grooves of both numbers. “Latona” was a slow burner from Big John Patton’s Let ‘Em Roll (featuring Green on guitar), gradually building throughout with Eddie Roberts’ mercurial guitar dancing over the song’s latin base and kept together by Alan Evans’ tight work behind the kit (eliciting Roberts to note that Evans “is the only drummer that I’ve heard play this right” outside of Otis “Candy” Finch on the original album).“Farid” was another number that stood out, as the group was clearly enjoying themselves (“I’ll have to add this to every set I ever play,” said Roberts laughing after the number), with the song steadily propelled forward by Alex Scott on bass and Evans’ cascading drum rolls, ultimately culminating in a drum solo for Evans where he let loose to show off his chops. It was followed by a stellar rendition of “Windjammer,” a buoyant and pulsating tune for which Roberts’ explosive guitar stylings led the way.After a break, during which special guest DJ Marcos Boricua returned with his funk-focused vinyl-spinning after kicking things off for the night, “Green Is Beautiful” picked up right where they had left off, this time with the addition of Jeff Franca of Thievery Corporation. Their first song, “Hey Western Union Man,” kept the crowd dancing after Boricua’s intermission music came to an end, with Nick Gerlach and Chris Spies building the melodic, groovy track to its climax. Gerlach again lent his expertise on sax in building up the next song, “Fancy Free,” working in and out of Roberts’ whorling guitar licks.During “Ain’t It Funky,” the title of the song rang true, with Chris Spies fiery stand-out performance behind the keys leading into a brief drum break giving Franca and Evans a moment to shine on percussion with one another’s company. The drums taking the spotlight recurred again in “Walk In The Night,” with the dark, grinding drums eventually dropping in volume to allow a dramatic return to the song’s main theme showcasing Eddie Roberts’ pristine and decisive guitar. Perhaps one of the crowd’s favorites of the night was “Day In The Life,” a nostalgic and happy-go-lucky carried by Eddie’s energetic playing.Friday night’s show at Cervantes’ was a stellar showcasing of both Grant Green’s work and the immense talent of those playing throughout the night. The audience members lucky enough to be in attendance at these intimate shows witnessed something special on Friday and Saturday night, something that we can hope will continue to be shared with the world with more future performances of Eddie Roberts’ “Green Is Beautiful” tribute.

The jamtronica favorites will follow up their December 29th at the Fillmore showing with at Denver’s intimate downtown music venue, Summit Music Hall, on December 30th. For this special performance, the band will offer up a special improvisational performance dubbed ‘Wave Spell’, which draws its name from the band’s recently released improvisation-focused album as well the group’s debut Belden Town, CA music festival in August. Finally, to ring in 2019, STS9 will be joined by Mark Farina and Mushroom Jazz for their New Year’s Eve proper performance, which will find the band returning to the Fillmore Auditorium on December 31st.For more information or for ticketing, head to STS9’s website here.last_img read more

Release Date Set for Big Screen Adaptation of Fences

first_imgDenzel Washington & Viola Davis in ‘Fences'(Photo: Joan Marcus) Fences has already won the Pulitzer Prize and the Tony, but could an Oscar be next? Denzel Washington’s big screen adaptation of the August Wilson play has been scheduled for a launch by Paramount on December 16, right in the middle of “awards season.” According to Deadline, the film will be released wide to movie theaters on Christmas Day.Tee film stars Washington and his former Broadway co-stars Viola Davis, Mykelti Williamson and Russell Hornsby. Both Washington and Davis won Tonys for their performances in the 2010 Main Stem revival; James Earl Jones led the 1987 original production.Fences is one of the 10 plays in Wilson’s Pittsburgh Cycle, focusing on the African-American experience in the 20th century. The play, which takes place in the 1950s, centers on Troy Maxson (Washington), a Pittsburgh sanitation worker who once dreamed of a baseball career, but was too old when the major leagues finally admitted black players. As he faces off against the racial barrier at work and his own disappointments, Troy also grapples with his son Cory over the teenager’s hope for a football scholarship and with his wife, Rose (Davis), who confronts Troy over a child he has fathered with another woman.

Women Wednesdays: Nurse’s marathon world record denied for wearing pants

first_imgRunner Jessica Anderson wanted to set the world record as the fastest woman to run a marathon dressed as a nurse. Anderson is a nurse, and has worked at the Royal London Hospital for nearly seven years. When she crossed the finish line of the London Marathon—wearing her scrubs—in three hours, eight minutes and 22 seconds, she beat the previous world record for a woman running a marathon in a nurse costume by 32 seconds. Nurse’s marathon world record denied because she wore pants Anderson was thrilled, until she learned that Guinness World Record rejected her application because she was wearing her scrubs “with trousers.” Guinness informed Anderson that a nurse’s uniform must include a blue or white dress; a pinafore apron and a traditional nurse’s cap and that the outfit she wore too closely resembled the dress requirements for a doctor’s uniform. Guinness World Records has since pledge to look into, and possibly update, it’s costume policy.last_img read more

The USPS a contender in financial disruption

first_img 9SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr by: Jim GhiglieriAmong the contenders in the race to disrupt the financial service industry is the U.S. Postal Service (USPS). Recently, the USPS issued a report talking through the different ways it may go about achieving this new opportunity, and one of those ways was to collaborate with community financial institutions (FIs). Of course, the organization has plenty of experience to potentially stand on its own two feet. It already is the largest single provider of paper money orders.It appears the audience they are most interested in courting is the unbanked and underserved, a segment that has become increasingly valuable to traditional FIs, as well. It certainly is a sizable market and one likely to offer unmatched loyalty and word-of-mouth marketing when trusting relationships are indeed solidified.“With well priced and carefully conceived products, these customers can be profitable,” Bank Director’s Joan Susie tells the Financial Brand. “Large banks, nonbank financial services companies and a few community bank pioneers are quickly realizing there is an even better reason than CRA credits to bank new immigrants and other underserved populations.” continue reading »last_img read more
