Australia’s Defense Minister derided a senior Chinese diplomat’s comments as “silly” and “comical,” after the latter dubbed Canberra’s trilateral nuclear-powered submarine pact with the US and UK a threat to peace.
During a television interview on Friday, Peter Dutton said acting Chinese Ambassador Wang Xining was “probably reading off a script from the Communist Party” when he warned that Australia would become the “naughty guy” if it procured the stealth-combat vessels through the AUKUS deal.
Wang, who is China’s most senior representative to the country after the previous ambassador’s term ended last month, told The Guardian on Thursday that Australia would be labeled a “sabre-wielder” rather than a “peace defender.” He said the Australian public “should be more worried” about the impact of the security pact their nation had made with the UK and the US.
There’s zero nuclear capacity, technologically, in Australia, that would guarantee you will be trouble free, that you will be incident free. And if anything happened, are the politicians ready to say sorry to people in Melbourne and in Adelaide?
However, Dutton “dismissed” the comments and countered that “most Australians [would] see through [their] non-productive nature.”
“We don’t see it from any other ambassador here in Australia. It’s quite remarkable,” the minister told the Nine Network, adding that “this type of diplomacy” was seen elsewhere in the world too.
“These provocative comical statements – it’s just so silly. It’s funny,” he added.
In September, Australian Prime Minister Scott Morrison announced the deal to obtain at least eight nuclear-powered vessels as part of its new defense alliance. The pact angered not only China but also France, which claimed it had been “stabbed in the back” after Canberra unilaterally scrapped a multi-billion-dollar diesel-electric submarine contract with Paris.
Last weekend, Dutton had irked Beijing by stating that he could not conceive of a situation in which Australia would hesitate to support the US should armed conflict with China break out over Taiwan. Under its ‘One China’ policy, Beijing has pledged to reunify the island with the mainland.
Wang warned Australian politicians on Thursday not to do anything that would be “destructive to our relationship.”
Objects, including spacecraft, could pierce through the universe using several black holes as a ‘shortcut’, a new study suggests.
The new theory posited by French physicist Pascal Koiran marks a break from earlier research in the field of black hole studies. Previously, it was thought that a so-called ‘wormhole’ composed of two black holes would be prone to instantly collapse, thus making it impossible for an object to successfully travel all the way from one side and out the other. However, by employing different metrics, the French scientist’s new model has arrived at a very different conclusion: “We show that the particle reaches the wormhole throat for a finite value t′1 of the time marker t′.” In essence, that means an object, for instance, a spacecraft, could pass through this wormhole portal intact and reach some far-away region of the universe, taking far less time than would be needed if traveling conventionally.
The study in its entirety will see the light of day in the upcoming issue of the Journal of Modern Physics D, though an abstract has been available since early October.
Yet, there are too many ifs as to whether this purely theoretical model has any bearing on the way the universe actually works. For starters, to create such a time-and-space tunnel you would need a regular black hole and a so-called white hole, which is essentially a black hole in reverse. While black holes never let anything out, their ‘twins’ never let anything in. So, according to Albert Einstein’s theory of general relativity and Nathan Rosen’s additions to it, if you were to connect the two, they would make up a bridge across time and space. However, if the laws postulated by another branch of physics, thermodynamics, are anything to go by, such a construct would be highly unstable. Perhaps more importantly, the very existence of white holes has yet to be proven beyond a reasonable doubt. At present, they remain a pure theorization, thus putting any talk of space-and-time portals on rather shaky ground.
The Chinese envoy to the European Union has reiterated Beijing’s goal of peacefully reuniting Taiwan with the mainland but stated the country’s preparedness to use “decisive measures.”
Speaking on Tuesday, China’s ambassador to the EU, Zhang Ming, said Beijing would never change its position on Taiwan. “If anything changes, it is that the Chinese people’s resolve to realize complete reunification of our country grows even stronger,” Ming told an online think tank event in Brussels.
“Some people in Europe seem to underestimate the Chinese people’s aspiration for a reunification of our country,” he added, noting also that the bloc must lift its sanctions if a new Sino-EU investment deal is to be ratified.
In May, Brussels halted an investment pact agreed with China last December, after Beijing imposed sanctions on several members of the European Parliament. The EU responded, introducing its own sanctions related to the treatment of the Uyghur people and alleged genocide in Xinjiang.
In recent years, China has become increasingly assertive about reuniting its wealthy island neighbor with the mainland. Beijing claims Taiwan is an inalienable part of the country and has called on Western parties to refrain from interfering in Chinese internal affairs. Western nations, notably the US and UK, have shown willingness to defend the democratic island.
Taiwan considers itself to be independent of China since 1949 when the communist forces overthrew the government of the Republic of China on the mainland, forcing the Kuomintang-ruled state to relocate there.
An exoplanet some 70% the mass of Jupiter and about 1.4 times its size has been discovered by astronomers at India’s Physical Research Laboratory (PRL). The behemoth is 752 light years away from Earth, and has an incredible orbit.
The new discovery was revealed by the Indian Space Research Organization on Tuesday in a statement saying the country’s PRL Advanced Radial-velocity Abu-sky Search (PARAS) had measured the movements of the newly-discovered exoplanet between December 2020 and March 2021.
The planet, named either HD 82139 or TOI 1789 depending on which cataloguing method is used, is ultra-hot – with a surface temperature up to 2,000 degrees Kelvin.
India’s PRL Advanced Radial-velocity Abu-sky Search (PARAS), an optical fiber-fed spectrograph, observed t he exoplanet and its movements from the Mt. Abu Observatory, according to the space agency. Not only is the planet ultra-hot, but it is also one of the closest to an orbiting star yet discovered.
The measurements obtained via PARAS were confirmed by Germany’s TCES spectrograph in April, and further verified by independent photometric observations from the PRL’s 43cm telescope, also located at Mt. Abu.
The exoplanet has an unusually quick orbit – a mere 3.2 days. The pace indicates that its distance from its host star is one-tenth the distance between Mercury and the Sun. This makes the exoplanet one of fewer than 10 such solar systems discovered thus far. Given the closeness to its host star – an aging orb 1.5 times the mass of the Sun – the new planet is also one of the lowest density planets yet discovered.
Planets so close to their host stars, with a distance less than 0.1 AU and masses between 0.25 to several times the mass of Jupiter, are known as “hot-Jupiters.”
The Indian space agency hailed the detection of the new planet as an opportunity to “enhance our understanding of various mechanisms responsible for inflation in hot-Jupiters and the formation and evolution of planetary systems around evolving and aging stars.” It is the second planet to be discovered by PARAS, with a previous discovery taking place in 2018.
An official inquiry has found that Germany’s justice system was staffed with former Nazis for decades after the Second World War, At one point, three out of four top officials at the prosecutor’s office were former party members.
Released on Thursday, the 600-page report was compiled by historian Friedrich Kiessling and legal scholar Christoph Safferling, and covers the Cold War period running from the early 1950s until 1974. The work was commissioned by the federal prosecutor’s office.
The researchers found that, at one point during the 1950s, roughly three in four top officials in the federal prosecutor’s office had been members of the Nazi Party. It took until 1972 before former Nazis were no longer in the majority in that office, and until 1992 before the judicial system had been fully purged of ex-members of the fascist party.
“There was no break, let alone a conscious break, with the Nazi past,” the researchers said of the situation.
Presenting the inquiry’s findings, state secretary at the justice ministry Margaretha Sudhof said the country has “long remained blind” to the presence of ex-Nazis in senior positions after the end of the Second World War.
“On the face of it they were highly competent lawyers… but that came against the backdrop of the death sentences and race laws in which they were involved,” Sudhof commented.
In a statement about the study’s publication, Justice Minister Christine Lambrecht said she welcomed “the fact that the Federal Prosecutor’s Office is also grappling with its troubled past and is shedding more light on its own Nazi entanglements in the post-war period.”
The federal prosecutor’s office is Germany’s highest prosecutorial authority, responsible for pursuing those who violate international law and commit alleged crimes relating to state security.
The latest study follows an earlier report published in 2016, which stated that in 1957 – more than a decade after the war had ended – 77% of senior officials in the justice ministry were former Nazis. At the time of that publication, then-Justice Minister Heiko Maas stated that the “Nazi-era lawyers went on to cover up old injustice rather than to uncover it, and thereby created new injustice.”
AstraZeneca has announced that its preventative antibody cocktail offers 83% protection against symptomatic Covid-19 for at least six months, making it more effective than its own vaccine.
In a statement on Thursday, AstraZeneca cemented its lead in the race to develop and market a preventative Covid-19 drug, which is delivered as a shot in the arm.
The drug, named AZD7442, reduces the risk of symptomatic Covid-19 by 83% over the course of six months, according to data from a trial in which participants were given one 300mg dose. There were no deaths or severe infections recorded within the trial group, it said.
A separate trial showed the drug reduced the risk of severe Covid-19 or death by 88% when administered within three days of the onset of symptoms.
“These new data add to the growing body of evidence supporting AZD7442’s potential … We are progressing regulatory filings around the world and look forward to providing an important new option against SARS-CoV-2 [Covid-19] as quickly as possible,” AstraZeneca Executive Vice President Mene Pangalos said in the statement.
The Anglo-Swedish firm has agreed to supply the US government with 700,000 doses of AZD7442 if the Food and Drug Administration grants it emergency use, which AstraZeneca requested on October 5. The firm has similar agreements with other nations.
The drug is created using a combination of two antibodies originating from immune B-cells donated by a recovering Covid-19 patient.
The treatment could be used in people who are known not to respond well to vaccines, such as cancer patients. Around 2% of people are considered to be at risk of not creating enough antibodies following the administration of a Covid-19 vaccine.
Based on the numbers, the drug appears to be more effective than the firm’s first-generation Covid-19 vaccine. Britain’s Zoe Covid study showed the effectiveness of the vaccine dropped to around 67% after four to five months.
Scientists have used an AI tool to identify which animals are most likely to contract and spread mutated versions of Covid-19. The model highlighted both pets and wild animals as likely reservoirs for the virus.
Using information about their habitats and various biological traits, researchers at the Cary Institute of Ecosystem Studies in New York developed the machine learning tool to figure out which animals had the particular ACE2 protein that the coronavirus was most likely to latch onto.
Out of 5,400 tested, the scientists narrowed it down to 540 mammalian species.
Some of its predictions have been previously documented as transmission risks, for instance, dogs, cats and bats, while farm animals like pigs and exotic zoo animals were surprise additions.
Other expected additions are minks, Sunda pangolins, and 35 species of bats – which are together ranked among the top 10% of animals most likely to spread the virus, in line with lab results.
The study, published in the Proceedings of the Royal Society journal, also ranked water buffalo, a number of primates, including gorillas and 76 rodent species as being more susceptible to infection.
The researchers taught the AI to identify patterns between rates of transmission and some 60 ecological and biological traits collected by earlier studies, including the overlap between the animal and human habitats as well as their respective lifespans, diets, and sizes.
Previously, the specific amino acid sequences had only been mapped out in around 300 species, including about 143 mammals — and figuring out which ones are more prone to infection is key to predicting the spread of the virus, researchers said.
Arinjay Banerjee at the University of Saskatchewan in Canada told the New Scientist that the results will help researchers “track viral infections and the possible emergence of animal-adapted coronavirus variants” around the world. Barbara Han, who led the study, said predictions needed to be followed up with systematic surveillance and lab studies.

A strike of more than 20,000 metal workers in Cadiz, Spain has halted the operations of key manufacturing plants, including Airbus and Alestis, with barricades erected, roads blocked, and vehicles burned.
Cadiz, the capital of the southernmost province of the country, has become one of the main sites of protests over working conditions. The Avenida de Astilleros is currently closed to traffic, with protesters burning vehicles.
Picket lines also blocked access to major shipbuilding and industrial sites of key local companies, such as Airbus, Navantia, Dragados, Alestis, and Acerinox, causing their work to be interrupted.
Protesters also cut off access to major industrial zones in Puerto Real and Campo de Gibraltar with barricades and bonfires. Rail traffic is also being obstructed, with pipes thrown onto the tracks.
The national police have been deployed to bring the situation under control and to protect the industrial sites. At one point on Tuesday, the strike turned into a full-scale confrontation, with protesters throwing rocks and screws at police, who reacted by firing rubber bullets. One person was arrested.
🎥🛑En #España 2º día y arden las calles de Cádiz en el segundo día de la #huelgadelmetal indefinida.
🔥🏴Todo nuestro apoyo a lxs trabajadorxs del sector del metal en #Cadiz.
The Federation of Metal Entrepreneurs (FEMCA), which represents major employers in the region, reiterated earlier its offer for dialogue with the workers, while stressing that the union’s requests were “unjustified” and “disproportionate.”
The workers say they will continue the strike until FEMCA provides them with an acceptable agreement.
