Texas Department of Family & Protective ServicesSpecial agents with the Department of Public Safety are being used to locate an estimated 2,800 children who have been deemed by the state as at high-risk for abuse. The DPS began assisting Child Protective Services in their efforts following a fiery meeting at the state capitol and a legislative ultimatum.As heard on Texas Public RadioPatrick Crimmins with the Texas Department of Family and Protective Services, the group who oversees CPS has confirmed that fewer than two dozen DPS special agents are working in Houston, Dallas and San Antonio, going door-to-door to find these kids, taking a picture on their phone, and sending it to a CPS caseworker.“I mean it’s kind of a welfare check kind of thing is what it is for the most part, but it is on a very limited basis, it’s only going to be Dallas, Houston and San Antonio,” Crimmins explains.Crimmins says DPS special agents are just there to “put eyes” on these children and lack the necessary jurisdiction to investigate children’s claims of abuse at this level unless they believe a crime has occurred.The emergency relief follows a tense hearing at the state capitol on Wednesday where senate lawmakers like Houston State Senator John Whitmire demanded the new head of CPS, Hank Whitman, take immediate action to find these at-risk children that no caseworker has seen in months.“Excuse me, you just said that they haven’t been seen, well hell they may die before you get there,” Whitmire told Whitman.Kate Murphy with the non-profit Texans Care For Children calls the effort a temporary fix of a much bigger problem because even after DPS special agents have located these children an individual CPS caseworker still has to conduct a follow-up visit with hundreds of families.“I think we need to start working right away with some real fixes to investigations, including hiring more caseworkers for investigations and paying higher salaries to stop turnover,” Murphy says.The head of CPS has requested the legislature allow his agency to hire an additional 550 caseworkers before the start of the 2017 legislative session.State lawmakers have demanded the head of Child Protective Services turn over his plan for turning the agency around by the end of Thursday.Copyright 2016 KSTX-FM.

By The Associated PressWhat began as a thin line swelled into a sea of sisterhood as hundreds of members of Delta Sigma Theta streamed into the rotunda of the Charles H. Wright Museum on Tuesday to pay tribute to the Queen of Soul, a member of the sorority.The moving ceremony, known as the Omega Omega Service, is not usually open to non-sorority members. The rare exception was the latest testament to the life and legacy of Aretha Franklin, remembered by her sisters as a proud Black woman who demanded respect and loved her community.Aretha Franklin lies in her casket at Charles H. Wright Museum of African American History during a public visitation in Detroit, August 28. (AP Photo/Paul Sancya)“She loved Delta and its ideals … she looked for the best in others. Her life was an inspiration,” said U.S. House Rep. Brenda Lawrence, a member of the sorority who was elected the first Black mayor of Southfield, Michigan, in 2001.At least 1,000 Delta Sigma Thetas from across the country attended the service, which lasted nearly an hour and is traditionally performed for any member before her funeral. Standing in a semicircle surrounding Franklin’s family, the women filed in for nearly 10 minutes wearing black dresses, pearl necklaces, and corsages of African violets, the sorority’s official flower.The traditional service saluted Franklin with words, scripture and songs.Particularly emotional was the singing of the Delta Prayer, which filled the rotunda as Franklin’s sisters serenaded her in unison.Franklin was inducted as an honorary member of Delta Sigma Theta in 1992. The sorority is among the cultural institutions she loved, including the Black church and historically Black colleges.Delta Sigma Theta was founded in 1913 at Howard University in Washington, D.C. Among its members are poet Nikki Giovanni, pioneering congresswoman Shirley Chisholm, entertainer Lena Horne, actresses Ruby Dee and Cicely Tyson and civil rights activist Dorothy Height.Franklin’s commitment to social justice and action was in keeping with Delta Sigma Theta’s roots and mission, said National President Beverly E. Smith.“She was a true, strong Delta and embodied who we are through the songs she sang, through the way she conducted herself and through the boldness she took in terms of social justice,” Smith said in an interview after the service. ”On the first day of her public viewing ahead of her funeral services on Friday, Franklin was resplendent in her sorority’s signature crimson. She wore the color from head to toe, including red Christian Louboutin stiletto heels, red lipstick and red nail polish.Thousands of mourners poured into the museum to pay their final respects to Franklin, who died Aug. 16 of pancreatic cancer at the age of 76. The two-day viewing was part of a week of commemorations for the legend.At the end of the Delta Sigma Theta ceremony, Franklin’s sorors filed past her polished bronze casket to say goodbye in a final act of sisterhood. Smith said that women came from across the country to show their respect and solidarity.“That’s the strength of the bond we have, making sure as black women we support each other,” Smith said. “They didn’t come from themselves; they’re just a number in the crowd. But they came to support one who meant something to us and who meant something to this country.”
By Mark F. Gray, Special to the AFROA rainbow covered the skies following the game-stopping thunderstorms signaling a smile from the heavens, when Maryland and Texas returned to play after an unexpected weather delay in the fourth quarter at Fed Ex Field. Perhaps it was the presence of the late Jordan McNair who needed to give the Terps a lift after they had blown a 22 point lead on an emotional day where his teammates remembered him from start to finish.McNair, the offensive lineman who passed away from heat stroke in June, was honored by his teammates with #79 decals on their helmets, a moment of silence with his image on the jumbotron, and by lining up with only 10 players for the game’s opening play. The late lineman may have been the intangible they needed to win.Jordan McNair was remembered by fans and teammates during a pregame moment of silence before their season opening game vs. Texas at FedEx Field. (Photo by Mark Gray)Maryland is playing for more than wins and losses this season, they are playing for McNair. Emotion can take teams a long way in sports and perhaps this was the start of a special season in College Park. The Terps had several chances to give in but ultimately pushed through a series of challenges that may have broken one of their lesser teams to beat Texas 34-29 for the second consecutive year on September 1.“We just stayed together which has been our motto through everything that’s happened,” said wide receiver Taivon Jacobs during the postgame press conference. “Everybody in our building just packed our parachute and stuck together.”Any doubts that Maryland was up to this emotional challenge was put to bed on their first drive. The Terps’ march downfield was choreographed better than the performance by their band. With Kasim Hill starting at quarterback for the first time since his season ended last year in Austin the offense was almost flawless.Maryland football players honored his memory with his jersey on the field after their 34-29 victory over Texas at FedEx Field. (Photo by Mark Gray)“Its been a long time since we played a football game and it was good just to be back out on the field with your brothers,” said Hill.Maryland’s freshmen were massive. The neophyte Terps contributed to every score. Jeshaun Jones, from D.C.’s Friendship Collegiate high school, was the star. He busted through the Texas defense for 28 yards and the game’s first touchdown to cap their opening drive. Jones also went deep against the Longhorn secondary for a 65-yard scoring reception. In the second quarter, Jones converted a jet sweep option by connecting with Tavion Jacobs for a 20-yard touchdown pass to give Maryland its biggest lead at 24-7.Jones scored three times in the first half placing himself in elite company. He became the first college player to score on a rush, reception and pass in his first game in 20 years.The Longhorns used their uptempo, offense to change the game’s momentum and took the lead. Texas scored 22 unanswered points behind sophomore quarterback Sam Ehlinger. Texas’ defense also stopped Maryland’s Jake Funk in the end zone for a safety which closed the gap to 24-22 at halftime. Ehlinger found Collin Johnson in the endzone on for a touchdown then Kyle Porter’s two-yard score gave Texas its only lead.Interim head coach Matt Canada’s leadership was tested also after both teams went to the locker rooms as the mini monsoon hit. He first had to re-establish the Terps offense after overcoming an 86 minute weather delay and conservative play calling that kept Texas alive. The Terps went 75 yards in just under five minutes for the game’s final and decisive score while their defense produced three fourth quarter turnovers to seal the game.The adversity of their offseason seems to have prepared them for challenges of the season to come at least for one big game.

Photoinduced nanobubble-driven superfast diffusion of nanoparticles imaged by 4D electron microscopy, Science Advances (2017). DOI: 10.1126/sciadv.1701160 Tiny particles suspended in hot liquid are observed to move in a seemingly random fashion. Such movement was noted by Robert Brown in the early 19th century, a phenomenon thus called Brownian motion. In more recent times, researchers have focused on Brownian motion as it relates to even smaller particles—micro and nano particles. Unfortunately, due to technological limitations, it was previously impossible to capture the action on film—instead, researchers have pieced together stills taken using an electron microscope. In this new effort, the researchers report on a technique they have developed that overcomes this problem, offering a new way to study diffusion of extremely tiny particles.The new approach involves the use of four-dimensional microscopy, which entails using both extremely fast laser pulses and transmission electron microscopy—it is based, the researchers note, on a pump-probe working mechanism. The first of two lasers excites the particles, while the second takes a picture of the action—it happens so quickly that the results can be viewed as video.In their experiments, the researchers fired a first pulse at gold nanoparticles, then fired a second pulse that captured images of tiny bubbles forming near the surface of the nanoparticles and exciting them. Increasing the energy of the first pulse, the team noted, resulted in merging many of the tiny bubbles, causing different types of movement by the nanoparticles. The researchers suggest their technique could be used by other researchers to study dispersion systems, particularly those that are out of equilibrium. It could also lead the way, perhaps, to the development of light-powered nanorobots working inside liquid systems. Play Results of nanoparticle experiment. Credit: Xuewen Fu © 2017 Phys.org
