Sunday, the NFL’s Seattle Seahawks drafted Brisbane, Australia native nose tackle Jesse Williams in the fifth round of the NFL Draft. Going into the draft, there were some expectations by the Brisbane Times and other media outlets that Williams might be selected in the first round. Injuries, which resulted in Williams being unable to participate fully in the NFL Combine, likely were reasons why he was not selected higher.

Gridiron football is not the most popular football code in Australia, with rugby league, rugby union, soccer, and Australian rules football all being more popular participation sports. Williams’ youth sporting career reflected this, with Williams playing rugby union until he was 15 years old at which time he switched codes and joined the local gridiron team, the Bayside Ravens. A year later, his playing ability earned him a scholarship offer from the University of Hawaii. He could not meet the university’s academic standards so eventually he attended Western Arizona Community College instead. In 2011, he transferred to the University of Alabama and played for the Alabama Crimson Tide for two seasons. Both seasons, his Crimson Tide team won the national championship.

Williams’ selection is unique amongst Australians as most Australians who have played in the NFL have been kickers. He is also only the second Australian ever to be drafted in the NFL Draft.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

The Australian Council of Trade Unions (ACTU) has urged the federal opposition Labor Party to focus on industrial relations (IR) as significant changes come into force from Monday 27th March. The legislation was passed in a row of controversy by parliament in December last year.

The contentious WorkChoices measures aim to move workers onto a federal industrial relations system and increase to the use of individual workplace contracts – under which conditions such as overtime and penalty rates can be set. The new WorkChoices arrangements include scrapping of unfair dismissal rights; the control by Federal government over state-based IR systems; more encouragement of individual contracts; award-cutting of award rates; secret ballots for industrial action and removal of the no-disadvantage test in new contracts.

The union movement has launched a fresh campaign to protest this week’s changes. ACTU secretary Greg Combet warns that some employees will feel the effects as soon as they come into force, because they will no longer be protected by the previous unfair dismissal laws. He says with the changes becoming enforced this week, the Federal opposition party must now concentrate on industrial relations and not on “political infighting”.

Australia’s Prime Minister, John Howard, says he’s prepared for a union scare-mongering over the IR laws, but assumes the campaign will fail. “I predict the scare campaign will go on,” he said. “I also predict that the scare campaign will fail.” Mr Howard says workers should wait and experience the new system for themselves and that the changes will give workers greater flexibility. “Over time it will be beneficial,” he said.

Combet feels different about the effects. “It’s likely, somewhere around Australia tomorrow, someone is going to be sacked unfairly and they’ll be the first victim of the new laws,” he told the ABC. “The really significant thing is that the balance of power in the workplace is shifting sharply to the business community, to the employer.”

Federal Workplace Relations Minister Kevin Andrews told reporters last week that “the sky would not fall, because people would go to work next Monday and not detect any difference.” He described union protests as “hysterical outbursts”. “There is nothing in this legislation that people need to worry about in the ordinary course,” he said.

Despite the Howard government’s increased majority in the Senate, the passing of bill has not been smooth. In November last year, hundreds of thousands of demonstrators rallied across the nation to express dissent of the IR legislation. Ex-Finance Minister, Senator Nick Minchin, said most Australians “violently disagree” with the recent IR changes and there was a real prospect that the High Court could overturn the Work Choices laws.

The HR Nicholls Society, described as one of Australia’s most politically conservative organisations, has likened the new federal laws to the former Soviet system of “command and control.” Society president Ray Evans says he does not like the centralised power being handed to the government under the changes, nor its encroachment on states’ rights.

Evans says the myriad of complex new laws would create a system where “so-called IR professionals would stand to make a lot of money sorting through it… every economic decision has to go back to some central authority and get ticked off,” he said . “There is a lot of that sort of attitude in this legislation and I think it is very unfortunate.”Kemalex Plastics owner Richard Colebatch of the HR Nicholls Society said the changes are “very complicated for anybody to decipher… The professionals will spend a lot of money, the employers’ money, working their way through the mire trying to create the new rules people are going to work towards.”

But the Prime Minister says “more jobs will be generated in the small business sector as a result of the removal of the absurd job-destroying unfair dismissal laws, and the greater flexibility for people to make workplace agreements at the enterprise level will lift productivity,” he told reporters in Melbourne. “Sure some people will complain, but a lot of people will benefit through getting job opportunities. Young people, who will get an opportunity to put their step on the bottom rung of the ladder for the first time, will benefit enormously.”

The Australian Medical Association (AMA) said WorkChoices regulations do not go far enough in clarifying who can legally issue medical certificates for sick leave. AMA vice-president Dr Choong-Siew Yong said WorkChoices regulations meant employers and employees faced uncertainty and confusion over sick leave.

“The regulations fail to acknowledge two very serious failings,” Dr Yong said in a statement. “One, if people are seriously ill, they should be seeing their medical doctor. Two, opening up medical certification to a whole range of non-medical practitioners will make it difficult for employers to take sick leave seriously.”

On Thursday, the United States Senate confirmed Ketanji Brown Jackson as an associate justice of the Supreme Court, becoming the first African American woman to sit on the Court.

The vote was 53 in favor of Jackson and 47 opposed, largely split along party lines between Democrats and Republicans, respectively. Susan Collins (Maine), Mitt Romney (Utah) and Lisa Murkowski (Alaska) broke ranks with their fellow Republicans to cast votes for Jackson. Vice President Kamala Harris presided over the vote. Had there been a deadlock, she would have cast a tiebreaking vote.

Jackson and President Joe Biden watched the proceedings from the Roosevelt Room of the White House. Biden nominated Jackson on February 25 to replace retiring Justice Stephen Breyer. In 2020, Biden promised while running for President to nominate a African American woman to the Supreme Court, the country’s highest. Presidential nominations are required to be confirmed by the Senate.

On March 21, Jackson was introduced to the Senate by Thomas B. Griffith, a former judge on the Court of Appeals for Washington, D.C. During her opening remarks, Jackson said: “My parents taught me that unlike the many barriers that they had to face growing up, my path was clearer, so that if I worked hard and believed in myself, in [the US] I could do anything or be anything I wanted to be.”

She closed with: “Members of this committee, if I am confirmed, I commit to you that I will work productively to support and defend the Constitution and this grand experiment of American democracy that has endured over these past 246 years. During this hearing I hope that you will see how much I love our country and the Constitution and the rights that make us free.”

On the second day of confirmation hearings, Senator Josh Hawley (Republican; Missouri) challenged Jackson on child pornography cases over which she had presided. He questioned a three-month prison sentence handed out by Jackson in United States v. Hawkins where the prosecution had sought two years imprisonment. Federal Sentencing Guidelines recommended eight years in the case, based on the number of images. Jackson responded that she disagrees with the current guidelines, arguing they fail to differentiate defendants, and are contentious by the Sentencing Commission.

Jackson explained: “Congress has given the judges not only the discretion to make the decision but required judges to do so on an individualized basis taking into account not only the guidelines but also various factors including the age of the defendant, the circumstances of the defendant.” The defendant in the case was eighteen years old.

On the third day of the hearings, Jackson was pressed on how to apply Constitutional provisions written over two hundred years ago, to current issues. Jackson responded: “It’s a process of understanding what the core foundational principles are in the Constitution, as captured by the text, as originally intended, and then applying those principles to modern day.”

Senators Lindsey Graham (Republican; South Carolina) and Ted Cruz (Republican; Texas) continued a line of questioning from Tuesday on light sentences which led head of the Judiciary Committee Senator Dick Durbin (Democrat; Illinois) to intervene numerous times on Jackson’s behalf. While Durbin said Jackson was being interrupted, he was accused of filibustering in the nominee’s favor.

On the fourth and final day of the hearing on March 24, Durbin announced the Judiciary Committee would meet on March 28, potentially setting up a vote on Jackson for April 4. That day, Jackson herself was not present on March 24 as the Senate heard testimony from other parties, such as Wade Henderson, president of nonprofit group the Leadership Conference on Civil and Human Rights. Henderson said of Jackson: “Her background is absolutely extraordinary and her demonstration and mastery of the law is second to none.”

Senator Marsha Blackburn (Republican; Tennessee) requested access to confidential pre-sentencing reports in Jackson’s past child pornography cases. Reports of this nature are confidential to protect the victims. Durbin refused, saying: “I would not want that on my conscience, that we did this for some political exercise here, which I think is totally unnecessary, and someone was harmed as a result of it. I’m going to resist it every step of the way.”

On April 4, the Judiciary Committee voted 11-11 on Jackson, a deadlock broken by a vote called by Senate Majority Leader Chuck Schumer (New York) which sent it to the Senate floor.

Prior to her nomination, Jackson served as a clerk for Breyer, a federal public defender, a federal district court judge and a member of the sentencing commission, as well as an attorney in private practice.

The Supreme Court has eight associate justices and one chief justice.

Reports say that O.J. Simpson, a former American football player is a suspect in a robbery that took place on Thursday night at the Palace Station Hotel and Casino in Las Vegas, Nevada. Simpson was not immediately arrested and was later released. He was not a guest at the hotel.

Las Vegas Metropolitan Police (LVMPD) began to question Simpson and at least five other people, after they were accused of breaking into a room in the hotel, with at least one of the individuals holding a gun, but its not known if the room was a guest room.

Several sports memorabilia items, all previously belonging to Simpson, were reported to be stolen from the room, which was registered to sports memorabilia collector Alfred Beardsley, and reports say that when police found the items, Simpson claimed that they belonged to him. Among the items stolen is believed to be a suit that Simpson wore during his 1995 murder trial, an autographed item that had been signed by Joe Montana, and “never before released” version of Simpson’s book If I Did It. Simpson was found not guilty of the murders of his ex-wife Nicole Brown Simpson and Ronald Goldman.

“When they talked to him, Simpson made the comment that he believed the memorabilia was his. We’re getting conflicting stories from the two sides,” said Jose Montoya, a spokesman for the LVMPD.

Reports say that Beardsley was going to sell the items and made plans to meet with someone on Thursday night who was interested in purchasing them. The unnamed individual, along with OJ claimed to be police officers and ordered Beardsley to turn over his cellular phone, which he refused. He then claims one of the men “roughed him up” before stealing every collectible in the room.

Police are expected to release a statement to the media later today.

News reports on Monday indicated authorities in Palestine, Texas identified a sixth victim following flash flooding late last week. Giovani Olivas, 30, was reportedly swept away in the flood.

In under an hour late Friday evening, Palestine was deluged by seven inches of rain, causing residents of one neighborhood to flee to their rooftops. Over 30 buildings, included many homes, in the city suffered significant damage.

Lenda Asberry, 64, a retired school teacher, and her four great grandchildren also drowned during the flood. Onlookers reported the woman was attempting to get the children to safety when they were swept away. Asberry’s daughter told reporters water levels were up to the woman’s neck while attempting to save the children.

One resident of the area told reporters “[her] furniture was floating around” inside her home, forcing her to climb atop her couch to seek safety.

Dark skies blanketed the nearby city of Tyler hours before the storm struck. At least one government office located in the Palestine area was closed on Monday and was slated to remain closed on Tuesday due to water damage. A tornado also ravaged much of nearby Lindale, Texas, resulting in severe damage of at least one residence. The storm system moved up along the US eastern seaboard over the weekend.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.
