NASA mission discovers Jupiter's inner secrets

by on 12:07 p. m.

NASA spacecraft Juno has collected new data on its mission to Jupiter revealing some of the swirling inner mysteries of the giant gas-planet.
The surface of Jupiter, the fifth planet from the sun and the largest in the solar system, consists of alternating bright and dark bands of gas and winds flowing in opposite directions at massive speed.
Previously there have been extensive studies of the helium-and-hydrogen planet's surface, but now gravity measurements collected by Juno indicate that this turbulent outer layer extends to a depth of 1,900 miles (3,000 kilometers).
    "Galileo viewed the stripes on Jupiter more than 400 years ago," Yohai Kaspi, Juno co-investigator from the Weizmann Institute of Science, Rehovot, Israel, and lead author of a Nature paper on Jupiter's deep weather layer, was quoted as saying on NASA's website.
    "Until now, we only had a superficial understanding of them and have been able to relate these stripes to cloud features along Jupiter's jets. Now, following the Juno gravity measurements, we know how deep the jets extend and what their structure is beneath the visible clouds," said Kaspi, who likened the advancement to going from a "2-D picture to a 3-D version in high definition."
    "On a gas planet, such an asymmetry can only come from flows deep within the planet; and on Jupiter, the visible eastward and westward jet streams are likewise asymmetric north and south.
    "The deeper the jets, the more mass they contain, leading to a stronger signal expressed in the gravity field. Thus, the magnitude of the asymmetry in gravity determines how deep the jet streams extend."
    The mission also found that the planet's interior rotates as a solid body, despite its fluid nature.
    "This is really an amazing result, and future measurements by Juno will help us understand how the transition works between the weather layer and the rigid body below," said Tristan Guillot, a Juno co-investigator from the Université Côte d'Azur, Nice, France, and lead author of the paper on Jupiter's deep interior.
    "Juno's discovery has implications for other worlds in our solar system and beyond."

    Memory Banda: Give girls choices, not lives already decided for them

    by on 12:06 p. m.


    Memory is a 22-year-old activist, advocating for girl's education and against child marriage. The opinions in this article belong to the author.
    Growing up in Malawi, one of the world's least-developed countries, exposes young girls to a number of risks -- some of which are life-threatening.
    Despite the fact that there are so many people advocating for gender equality, women and girls still do not have much choice when it comes to taking control of their own lives. This often comes down to cultural traditions that seem at times impossible to overcome.
    I have witnessed many injustices against women and girls in my country. It is so sad to see girls in life-threatening situations when they are so young, preventing them from exploring opportunities that would give them a completely different life.
    When I was a little girl, I used to see my relatives, friends and schoolmates going through a rite of passage to adulthood. We all grew up knowing we would have to go through this at some point ourselves -- whether we understood what was happening to us or not. After all, we did not have a choice. It was something that the community expected of us.
    In Malawi, there are numerous traditions that girls must go through as they approach adulthood. Girls as young as 10 are expected to go to "chinamwali" -- a camp where they are taught how to sexually please a man.

    Leymah Gbowee: The people have awoken, we need to make the most of this moment

    by on 11:18 a. m.




    Earlier this year, my daughter Pudu attended the second Women's March in Los Angeles. She later sent me an email saying that she felt excited to be part of the march.
    The protesters' signs used humor and anger to counter the policies of the US administration. She looked out over a sea of people wearing pink "pussyhats" as they listened to speeches about the harm being done by current political and social systems.
    But she left the Women's March with a big question: what is this for?
    She wondered what our traffic jams, road closures and rousing speeches achieved since, once we put the signs away, we still live in a sexist, patriarchal world. A world where undocumented children risk deportation, where the poorest members of society are denied basic rights and where the color of your skin can make you a target for violence.
    Knowing my history of bringing women together to create change, she asked me if we march only to hear ourselves chant -- because she sees little evidence of the protests creating change.
    I believe it takes a village to raise children, so I asked my good friend and American feminist Abigail Disney to share her reflections with my daughter.
    Even in the face of Donald Trump's election, Abby has faith in the American people's ability to change society for the better. She shared how the election prompted many people to try to understand what their personal responsibilities are.
    "We need to make the most of this moment, where it feels like a lot of people have awoken from a deep, apathetic slumber."




    Abby encouraged my daughter not to be disheartened if the world looks bleak. In Abby's words: "Don't ever forget that almost every time history has taken a great leap forward, it has looked worse than ever. I will never forget when the Berlin Wall fell. It had never felt less likely. And there it was -- without a shot fired -- just crumbling."
    Reflecting on our joint feminist activism, Abby told Pudu that real change is slow, it is hard and it takes a lifetime of work. She emphasized the need for solidarity, and the importance of encouraging the newer protesters to keep organizing marches, writing petitions and running for office. We need to make the most of this moment, where it feels like a lot of people have awoken from a deep, apathetic slumber.
    Abby and I both agree that anger can be an incredible motivator, but you cannot let go of optimism, or your anger will start to control you. I believe that huge gains have been made, and when we take a generational view, we can see how much has changed.
    When my mother was a young woman in Liberia, she had five daughters. At the time, this was considered a curse because she didn't have a son. In fact, my name, Leymah, means: "What is it about me?" because my mother was hoping to conceive a boy.
    Turn to my generation. I am the proud mother of eight children. My mother and grandmother taught me to be independent and I owe my feminist education to them, because they told us that we could do whatever a boy could do.
    Today, my generation is boldly organizing marches, wearing pussyhats and writing outrageous slogans on their placards. We place value on girls' education and have tried to raise our daughters in a way that celebrates their strength, courage and wisdom. We do not see girls to be a curse; rather we see them as a blessing.

    UK slams 'brazen' attack on Russian spy as Moscow suspicions grow

    by on 11:12 a. m.
    UK Home Secretary Amber Rudd condemned the attempted assassination of a former Russian spy and his daughter in England as "cruel" and "brazen" on Thursday, amid growing suspicions that Moscow may have been involved.

    Police confirmed Wednesday that a nerve agent was used in the attack in the southern English city of Salisbury on Sergei Skripal and his daughter, Yulia, who remain in a critical but stable condition.
    In a statement to members of Parliament on Thursday, Rudd refused to be drawn on who might have been responsible.
    "The use of a nerve agent on UK soil is a brazen and reckless act -- this was attempted murder in the most cruel and public way," Rudd said.
    "People are right to want to know who to hold to account but if we are to be rigorous in this investigation we must avoid speculation and allow the police to carry on their investigation."
    Rudd said the UK government was committed to "doing whatever we can to bring the perpetrators to justice" and would "act without hesitation as the facts become clearer."

    Skripal, 66, and Yulia, 33, were found slumped on a bench near a shopping center in Salisbury on Sunday. A police officer who helped them was also exposed to the nerve agent but his condition has improved.
    Earlier Thursday, Rudd said that Skripal and his daughter were in a "very serious condition" but that the policeman was "talking and engaging."
    Police: Pair 'deliberately targeted'
    In a statement on Wednesday evening Mark Rowley, the head of the counter-terrorism division at London's Metropolitan police, declared a "major incident" and said hundreds of police officers, forensic experts and government chemical analysts were involved in the inquiry.
    Rowley said the attack was being treated as attempted murder, and that Skripal and his daughter were deliberately targeted.
    If a Moscow link were proved, it would plunge relations between the West and Russia to a new low, and would call into question the British government's ability to protect residents of the UK at home. Rowley said officers from Wiltshire police, the local force, were providing support to the sick officer and his family.
    Sally Davies, the Chief Medical Officer for England, said the evidence did not suggest any wider danger to the public.


    A White House taken by storm ( Donal Trump )

    by on 10:56 a. m.
    Stormy Daniels is playing Donald Trump at his own game.
    The adult movie star, who claims she had an affair with Trump and was paid $130,000 to stay quiet before the election by the President's lawyer, has drawn the White House into a politically damaging sexual melodrama.
    Daniels turned her case from a side show muffled by multiple controversies battering the administration into a West Wing headache using methods that Trump, the high priest of self publicity, would recognize.
      Building buzz with the garish theatrics of a reality show protagonist and offering suggestive interviews that hinted at hidden bombshells, Daniels then weaponized the courts to target a foe who has no desire to fight.



      hat's how White House press secretary Sarah Sanders found herself sparring Wednesday with reporters demanding to know if her boss was trying to silence the porn star after an alleged liaison a decade ago.
      Her answers only prolonged the drama and exacerbated its political toll. Trump was furious with Sanders over her responses on Wednesday, a source close to the White House told CNN's Jim Acosta.
      "Sarah gave the Stormy Daniels storyline steroids yesterday," the source said.
      Among the questions left hanging on Thursday morning: Did Trump's team try to stop a damaging scandal emerge just before the 2016 election? Did Trump know about the payment himself? Is the President still involved in what Daniels' lawyer says is an ongoing attempt to intimidate her?
      If the mess isn't cleared up soon, it could ding Trump's already compromised image ahead of midterm elections that are crucial to his political fate.
      There is so far no evidence of wrongdoing by the President and he has denied the alleged affair.
      But as details emerge of a covert litigation battle between Trump's personal attorney Michael Cohen and Daniels' representatives, Trump, already fuming at a special counsel probe, could find himself in yet more legal peril.


      Trump asked witnesses about special counsel conversations

      by on 10:51 a. m.


      President Donald Trump reportedly asked his former chief of staff Reince Priebus if special counsel investigators had been "nice" during his interview, according to The New York Times, citing two people familiar with the conversation.

      Special counsel Robert Mueller's investigators are aware of two occasions where Trump asked witnesses about conversations they had with investigators, The New York Times reported Wednesday, citing three people familiar with the encounters.
      In the other instance, Trump reportedly told an aide that White House counsel Donald McGahn should put out a statement denying a previous Times report -- in which the paper said McGahn told investigators that Trump asked him to fire Mueller.
      The special counsel's investigation is currently one of several probes looking into Russian meddling in the 2016 election and whether Trump campaign associates have any ties with Russians.
      Trump has repeatedly denied any collusion.
      Earlier this week, CNN reported that a Middle East specialist with ties to Trump's team attended secret meetings during the presidential transition between the United Arab Emirates and Trump associates, and is now cooperating with special counsel Mueller, according to two people familiar with the matter.
      The special counsel's questions about the Emiratis point to an investigation that has expanded beyond Russian meddling in the 2016 election to broader concerns about foreign influence during the presidential campaign and long after it concluded.
      Additionally, CNN reported last month that Mueller's team has been asking witnesses about Trump's business activities in Russia prior to the 2016 presidential campaign as he considered a run for president.
      CNN's Kara Scannell, Pamela Brown, Gloria Borger and Jim Sciutto, Shimon Prokupecz, and Sara Murray contributed to this report.

      Trump anula DACA, el programa que protegía a los "soñadores" de la deportación

      by on 10:31 a. m.
      l secretario de Justicia Jeff Sessions anunció este martes en rueda de prensa que será anulado el programa conocido como DACA, que protegía a los "dreamers" o "soñadores" de la deportación. El futuro de 800.000 jóvenes queda en incertidumbre.
      El programa de la era de Barack Obama protegía a los jóvenes inmigrantes que habían llegado a EE.UU. como niños junto a sus padres.
      "El programa es inconstitucional", dijo Sessions en rueda de prensa, y añadió que el presidente Donald Trump estaba haciendo lo que prometió en campaña.

      (CNN Español) - El secretario de Justicia Jeff Sessions anunció este martes en rueda de prensa que será anulado el programa conocido como DACA, que protegía a los "dreamers" o "soñadores" de la deportación. El futuro de 800.000 jóvenes queda en incertidumbre.

      El programa de la era de Barack Obama protegía a los jóvenes inmigrantes que habían llegado a EE.UU. como niños junto a sus padres.

      "El programa es inconstitucional", dijo Sessions en rueda de prensa, y añadió que el presidente Donald Trump estaba haciendo lo que prometió en campaña.



      Luego de las palabras de Sessions, Trump emitió un comunicado explicando la decisión de anular el DACA.

      "No estoy de acuerdo en castigar niños, que la mayoría ya son adultos, por las acciones de sus padres", dijo.

      Añadió que el país debe "reconocer que somos una nación de oportunidad porque somos una nación de leyes".

      Especificó que las prioridades "no han cambiado. Estamos enfocados en criminales, amenazas a la seguridad, cruces en la frontera, quienes exceden sus visas y criminales que infringen varias veces la ley".

      Sin embargo, horas después, cuando se le preguntó por esta determinación, el presidente aseguró que "el largo plazo va a ser la solución correcta".

      "Tengo un gran afecto por estas personas de las que estamos hablando. Un gran amor por ellos y la gente piensa en términos de niños, pero en realidad son adultos jóvenes... Con optimismo, ahora el Congreso podrá ayudarlos y hacerlo de la manera correcta. Y yo les puedo decir, hablándoles a los miembros del Congreso, que ellos quieren poder hacer algo y hacerlo bien. Realmente no tenemos ninguna alternativa, debemos poder hacer algo... Y el largo plazo va a ser la solución correcta", fueron las declaraciones de Trump.
