South Australia enters week-long lockdown to contain COVID-19 Delta variant spread

Friday, July 23, 2021

With five active cases of the Delta variant of COVID-19, South Australia begun a one-week lockdown on Monday. Announcing the lockdown, state Premier Steven Marshall declared “we have no alternative but to impose some fairly heavy and immediate restrictions”.

The first case out of South Australia’s active cases was presented to Modbury Hospital on Sunday night, having returned from Argentina earlier this month. The fifth, which Premier Marshall noted as “far more worrying”, visited The Greek on Halifax restaurant at the same time as someone who was later confirmed to be carrying the virus. Chief Public Health Officer for the state Nicola Spurrier said “if anyone has been at The Greek on Halifax they need to get into quarantine and get tested”.

In accordance with new regulations, there are only five reasons for South Australians to leave home: essential work, shopping for essential goods such as food, exercise, but only with people from the same household and within 2.5 kilometers (2 mi) of home, medical reasons (which includes testing and vaccination against the coronavirus, but excludes elective and cosmetic surgery), and caregiving.

Schools have closed for all but children of essential workers, with online learning having begun on Thursday. Face masks are also be mandated for those who leave home. ABC News reported that “support for businesses is expected to be announced…”, with all non-essential retail required to close under the new regulations.

What would you tell your grandchildren about 2007 if they asked you about it in, let’s say, 20 year’s time? If the answer to a quiz question was 2007, what would the question be? The year that you first signed on to Facebook? The year Britney Spears and Amy Winehouse fell apart? The year author Kurt Vonnegut or mime Marcel Marceau died, both at 84?

Let’s take a look at some of the international stories of 2007. Links to the original Wikinews articles are in bold.

Wikinews correspondent J.J. Liu spoke with Technological University Dublin (TUD) senior lecturer at the School of Surveying & Construction Management, Dr Lorcan Sirr on Friday regarding the supply of housing in the Republic of Ireland and relevant parallels across the rest of Europe, as well as recent developments by the government and private sector that are causing a rise in rents and home prices in the Irish real estate market.

Dr Sirr is a regular contributor to The Irish Times and has provided commentary to Irish radio station Newstalk, national broadcaster Raidió Teilifís Éireann (RTÉ) and various other publications. In addition to being a chartered planning and development surveyor and assessor to the Society of Chartered Surveyors, Dr Sirr is a Peace Commissioner and former external examiner for the Galway-Mayo Institute of Technology, according to his profile on Worky.

Dr Sirr was a lecturer and former head of research for the Faculty of the Built Environment at the Dublin Institute of Technology, which entered a merger with two partner institutes to become TUD January 1, 2019. He received his bachelor’s degree in estate management at the University of Greenwich, United Kingdom, and master’s degree in urban design and PhD in town planning at the University of Manchester. He has a second master’s in literature from KU Leuven, Belgium, and speaks French.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

On Friday, French capital football club Paris Saint-Getmain announced they loaned Italian goalkeeper Salvatore Sirigu to Spanish club Sevilla F.C. till the season end.

29-year-old Sirigu started his career in Italy and joined the Parisians five years ago, in 2011. After playing 60 Serie A matches from 2009 to 2011, Sirigu became the first-choice goalkeeper at PSG for four years, playing 145 matches.

In five seasons at Parc des Princes, Sirigu has won four consecutive Ligue 1 titles, three Trophée des Champions, three Coupe de la Ligue, and two Coupe de France. Sirigu has played seventeen international matches, debuting in 2010.

Last season, German goalkeeper Kevin Trapp joined PSG and became their first-choice keeper. Lacking playing time with PSG, Sirigu signed the contract with Sevilla on Friday, after passing the medical tests hours before.

Per the agreement between the clubs, PSG has not included an option for Sevilla to buy the player.

This morning local time an explosion, now officially considered a terrorist incident, was reported on a London underground train which was stopped at Parsons Green in south-west London.The explosion has been officially confirmed caused by an improvised device placed in a white bucket inside a Lidl shopping bag. Reports also indicate a timer attached to the explosive. At least 29 people were injured, NHS England said this afternoon.

Officers and ambulance staff were on the scene this morning, with reports of burn and crush injuries. Detectives and MI5 were investigating.

BBC News presenter Sophie Raworth described seeing a woman on a stretcher with face and leg burns.

In a statement after the incident, British Prime Minister Theresa May said, “My thoughts are with those injured at Parsons Green and emergency services who are responding bravely to this terrorist incident.”

A team of researchers from the University of Tennessee, Knoxville, has confirmed that near-Earth asteroid (29075) 1950 DA is primarily held together by van der Waals forces rather than gravity. They have shown that the rotation rate of the 1.1 km asteroid is higher than could be possible if only gravity and friction were responsible for holding it together. Cohesive forces prevent large scale shedding of material and breakup of the asteroid. Their study was published Wednesday in Nature.

The researchers found that the bulk density 1.7±0.7 g/cm³ of the asteroid is approximately two times lower than the value required for self-gravity to balance out the centrifugal forces caused by rotation. As Ben Rozitis, a planetary scientist and a co-author of the study, told Space.com: “I was expecting to find a high-density metallic asteroid, as such an asteroid wouldn’t require cohesive forces to hold itself together under its fast rotation. Instead we found the opposite! […] We knew from previous work that this asteroid was rotating faster than it should be, and we wanted to know why”.

Spectral observations of 1950DA indicated that it is either an E- or M-type asteroid in the Tholen classification. However, its low optical albedo and low radar circular polarization ratio (a very smooth surface at centimetre to decimetre scales) showed that it cannot be an E-type asteroid.

Unusually for an M-type asteroid (which are mostly metallic), 1950DA has low radar albedo. It would have been puzzling, if it was not for the Rosetta observations of 21 Lutetia, which is also an M-type asteroid with very similar low radar albedo. Researchers have used for 1950DA the same meteorite analogue which was earlier found to fit best 21 Lutetia: enstatite chondrite with grain density of 3.55 g/cm³. It allowed to calculate macro-porosity of 51±19%, indicating that 1950DA is a rubble-pile asteroid.

Taking into account thermal-infrared measurements of thermal inertia, presence of a fine-grained regolith is implied, primarily around 1950DA’s equator. Negative ambient gravity near the equator of the asteroid (48±24% of its surface) requires existence of cohesive forces to prevent loss of material. This is similar to an effect noticed between the fine grains of regolith on the Moon. Lunar regolith was found to be highly cohesive because of van der Waals forces between grains by the Apollo 17 expedition in 1974.

As Ben Rozitis explained: “We found a low-density rubble pile that traditionally would be unable to hold itself together unless cohesive forces were present. It’s exciting because we’ve provided the first evidence that cohesive forces are important for small asteroids, which had only been predicted up until now.”

The balance between cohesion and negative gravity requires small grain sizes consistent with the grain size distribution on 1950DA, and similar to that of another rubble-pile asteroid, (25143) Itokawa. Unlike Itokawa, 1950DA does not have large boulders on the surface; they may have been lost as 1950DA’s rotation accelerated due to YORP effect. This effect results in a change of the rotation rate of an asteroid (either faster or slower), and is caused when the Sun heats up an object unevenly, due to asymmetric surface topography. As the heat escapes, the rotation rate is slowly changed due to an uneven rate of cooling. The researchers find that a rubble-pile asteroid may have a high rotation rate, if it is held together by cohesive forces between the grains. But as the spin rate increases due to YORP effect, the centrifugal force may cause the rubble pile to eventually separate as it happened with P/2013 R3.

The findings may have implications for asteroid impact avoidance. A very small impulse may break one potentially hazardous object into several pieces. As Ben Rozitis said: “You’d want to avoid interacting with the asteroid directly. An alternative is to use a ‘gravity tractor,’ or a heavy spacecraft placed near the asteroid, which uses the force of gravity to pull the asteroid off course”. Bong Wie, an aerospace engineer at Iowa State University in Ames, noted: “I just hope that an asteroid on a collision course with Earth will not be spinning rapidly and it will not be a rubble-pile asteroid”.

According to Daniel Scheeres, an aerospace engineer at the University of Colorado, Boulder, understanding such cohesive forces may also be important for future asteroid mining. Ben Rozitis clarified: “Mining missions intend to visit small asteroids about 10 meters (33 feet) or less in size, as it is thought that they are predominantly solid bodies. However, cohesive forces enable such small asteroids to be rubble piles instead. A small rubble-pile asteroid would be harder to interact with and collect, as it can easily deform or break up when subject to external forces.”

The study was supported by Jet Propulsion Laboratory, California Institute of Technology and the NASA.
