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.
France shouldn’t remain silent on Julian Assange, leftist leader Jean-Luc Melenchon has said, after the imprisoned WikiLeaks co-founder’s father suggested that Paris could offer asylum to his son.
The life of Assange – who is being held in solitary confinement at London’s Belmarsh maximum security prison while a British court considers an extradition request by the US – is under threat, Melenchon wrote on Twitter on Tuesday.
“For years, we’ve been calling for France to accept him,” the head of the leftist La France Insoumise (France Unbowed) party said, insisting that “France shouldn’t remain silent.”
The statement by Melenchon, who won 19.6% of the ballot in the first round of the French presidential election in 2017, follows a visit by Assange’s father, John Shipton, to the Whistleblower Meeting in Paris on Monday.
During the event, Shipton told Sputnik news agency that it would be “an honorable thing” for the French government to grant his son asylum.
“I feel that France hasn’t attacked Julian over the last 12 years and consequently France is free to act in return for the information that WikiLeaks and Julian brought to France,” he said, referring to the website’s revelations of the US intelligence agencies spying on French presidents and hacking into local banks.

Several dozen French lawmakers have also recently called upon Paris to take Assange in, with the Australian-born publisher’s legal team saying last year that their client was hoping to find asylum on French soil.
Assange could face up to 175 years behind bars if he’s extradited to the US, where he’s wanted on espionage charges over the release by WikiLeaks of classified documents on Iraq, Afghanistan, Guantanamo Bay, and others.
He was placed in Belmarsh in April 2019 over breach of bail, after being holed up in the Ecuadorian Embassy in London for seven years.
The publisher had been fleeing an arrest warrant issued over sexual assault allegations which he has always denied, and which failed to result in any actual charges due to lack of evidence.
Assange’s supporters insist that he has actually been persecuted over his legitimate journalistic activities and revealing the truth to the public.
The UK High Court is expected to rule on the appeal by the US against a lower court decision to bar the WikiLeaks co-founder’s extradition to America due to the 50-year-old’s poor health condition and risk of suicide.
Assange’s team will then be able to challenge the ruling in the Supreme Court if it’s not favorable.

Scientists have used artificial intelligence to “predict” formulas for new designer drugs, with the stated goal of helping to improve their regulation. The AI generated formulas for nearly nine million potential new drugs.
Researchers with the University of British Columbia (UBC) used a deep neural net for the job, teaching it to make up chemical structures of potential new drugs. According to their study, released this week, the computer intelligence fared better at the task than the scientists had expected.
The research team used a database of known designer drugs – synthetic psychoactive substances – to train the AI on their structures. The market for designer drugs is ever-changing, since their manufacturers are constantly tweaking their formulas to circumvent restrictions and produce new “legal” substances, while cracking their structure takes months for law enforcement agencies, the researchers said.
“The vast majority of these designer drugs have never been tested in humans and are completely unregulated. They are a major public-health concern to emergency departments across the world,” one of the researchers, UBC medical student Dr. Michael Skinnider has said.
After its training, the AI was able to generate some 8.9 million potential designer drugs. Afterwards, researchers ran a data sheet of some 196 new drugs, which had emerged in real life after the model was trained, and found that more than 90% of these have been already predicted by the computer.
“The fact that we can predict what designer drugs are likely to emerge on the market before they actually appear is a bit like the 2002 sci-fi movie, Minority Report, where foreknowledge about criminal activities about to take place helped significantly reduce crime in a future world,” senior author Dr. David Wishart, a professor of computing science at the University of Alberta, has said.
Identifying completely unknown substances remains an issue for the AI, the research team has noted, but they hope it might potentially help with that task, since the computer was also able to predict which formulas of designer drugs were more likely to be created and hit the market. The model “ranked the correct chemical structure of an unidentified designer drug among the top 10 candidates 72 percent of the time,” while throwing in spectrometry analysis, which is an easily obtained measurement, bumped the accuracy to some 86%.
“It was shocking to us that the model performed this well, because elucidating entire chemical structures from just an accurate mass measurement is generally thought to be an unsolvable problem,” Skinnider stated.

The Swedish government has announced plans to introduce mandatory Covid-19 passes starting next month, amid rising infection rates in Europe. The passes will be required to attend any indoor event with 100 or more participants.
The upcoming introduction of mandatory coronavirus vaccine passes was announced by Health Minister Lena Hallengren on Wednesday.
Citing the ongoing surge in coronavirus cases across Europe – which has not hit the country itself yet – the minister stressed the need to be ready for the new wave of infections, projected to reach Sweden mid-December.
“The spread is increasing in Europe. We haven’t seen it yet in Sweden, but we are not isolated,” Hallengren told a news conference. “We need to be able to use vaccination certificates.”
Starting from December 1, the documents confirming a person’s vaccination status will be a requirement to enter any indoor event with 100 or more people in attendance. Sweden already boasts high vaccination rates, with 85% of its citizens aged over 16 having received at least one dose of a Covid-19 vaccine. Over 81% have received two shots or more, public health data shows.
Earlier in the day, the country’s health authorities backtracked on a highly controversial decision to stop testing fully vaccinated people who showed symptoms of Covid. The recommendation was rolled out in October, leading to a 35% decline in Covid-19 tests taken.
“The Public Health Agency has decided to recommend that the regions offer testing to everyone who is 6 years and older who gets symptoms that may be COVID-19,” the health authority said in a statement.
Sweden bucked the trend among European governments in its approach to handling the pandemic, electing not to impose widespread lockdowns. Having relied primarily on voluntary measures and social distancing, the country displayed several times higher death rates per capita than its Nordic neighbors, though it still fared better than many European countries, registering some 1.18 million cases and just over 15,000 coronavirus deaths since the beginning of the pandemic.

Brazil’s former President Luiz Inacio Lula da Silva has said he is willing to stand as a candidate in elections against incumbent leader Jair Bolsonaro, labelling his potential opponent “a poor copy of Trump.”
Speaking in Brussels at a media conference in the European Parliament on Monday, Lula announced that the Workers Party needs to put forward a presidential candidate to take over from right-wing Bolsonaro in 2022 and said he was willing to run in the elections again.
“I’m willing, I’m motivated, I’m in good health,” Lula stated, adding that said he would only make his decision early next year, some months before the election scheduled for October 2022. The popular leftist said his candidacy would depend on whether the party wanted him.
“We need to have someone who stands, we need to win the elections. And at the same time, we have to rebuild Brazil,” he said, speaking on behalf of his Workers Party.
Lula, 76, also took aim at the incumbent president. “He’s a poor copy of Trump. But Bolsonaro doesn’t think, he doesn’t have any ideas,” the former president said, claiming the incumbent leader was hellbent on ensuring the beneficial legacies of Lula’s administration were “torn down.”
A recent poll put him 27 points ahead of Bolsonaro, despite his candidacy not officially being announced.
In 2010, Lula made way for his protégé, Dilma Rousseff. Rousseff was ousted from power in what was described by her supporters as a parliamentary coup. Lula served nearly two years in prison after being convicted on money laundering and corruption, despite a nine-and-a-half-year sentence. He was also barred from running in the 2018 election.
A number of judges have subsequently ruled that the case against Lula was unlawful and the Supreme Court annulled his earlier convictions, meaning he can face off against Bolsonaro in 2022.

Amid a surge in Covid-19 cases, Gibraltar has canceled official Christmas events and “strongly” discouraged people from hosting private gatherings for four weeks. Gibraltar’s entire eligible population is vaccinated.
The government of Gibraltar recently announced that “official Christmas parties, official receptions and similar gatherings” have been canceled, and advised the public to avoid social events and parties for the next four weeks. Outdoor spaces are recommended over indoor ones, touching and hugging is discouraged, and mask wearing is advised.
“The drastic increase in the numbers of people testing positive for Covid-19 in recent days is a stark reminder that the virus is still very prevalent in our community and that it is the responsibility of us all to take every reasonable precaution to protect ourselves and our loved ones,” Health Minister Samantha Sacramento said.
Gibraltar, a tiny British Overseas Territory sharing a land border with Spain, has seen an average of 56 Covid-19 cases per day over the last seven days, up from fewer than 10 per day in September. The rise in cases, described by the government as “exponential,” comes despite Gibraltar having the highest vaccination rate in the world.
More than 118% of Gibraltar’s population are fully vaccinated against Covid-19, with this figure stretching beyond 100% due to doses given to Spaniards who cross the border to work or visit the territory every day. Masks are still required in shops and on public transport.
The initial vaccine campaign on the British outpost came to a conclusion in early spring 2021, with a large proportion of the population fully inoculated against Covid-19. It became one of the first places in Europe to reduce restrictions following a winter of lockdowns, in what was dubbed ‘Operation Freedom’.
Gibraltar is currently doling out booster doses to the over-40s, healthcare workers, and other “vulnerable groups,” and administering vaccines to children aged between five and 12.
Similarly well-vaccinated countries have also reported surges in Covid-19 infections recently. In Singapore, where 94% of the eligible population have been inoculated, cases and deaths soared to record highs at the end of October, and have since subsided slightly. In Ireland, where around 92% of the adult population is fully vaccinated, cases of Covid-19 and deaths from the virus have roughly doubled since August.
The annual migration of red crabs has brought traffic to a standstill on an Australian island. Apart from the epic journey, the species is also notorious for eating its own young.
Tens of millions of crustaceans are swarming Canberra-governed Christmas Island, which is almost a thousand miles northwest of the Australian mainland. Parks Australia, a government body in charge of wildlife conservation on the island, has deployed its staff to manage traffic, rake crabs off roads and provide advisories to local residents regarding road closures. Authorities are well-prepared to deal with the epic crab march as it repeats every year, usually in October and November. There are even special bridges and tunnels in place, built over and under busy roads so as to minimize the number of crabs crushed by cars. The sight of millions of these creatures making their perilous trek has become one of Christmas Island’s main tourist attractions.
The exact timing of the red crabs’ journey from forest to ocean is defined by rainfall and lunar phases. The march is led by male crabs, which are later joined by females. On reaching the ocean, they mate and spawn, with each female capable of producing as many as 100,000 eggs. However, most of the young crabs never make it back to the forest as they end up being eaten by fish and whale sharks for whom this is a veritable feast. To make matters worse, the crab larvae that do make it to the beach are often devoured by returning adult crabs of the very same species, hence one of their names – the cannibal crab.
Clinics in the Austrian region of Salzburg have set up a special assessment team tasked with identifying Covid patients who have a higher chance of survival; the rest may soon have to take a back seat.
Amid a dramatic spike in Covid cases, medical personnel warn they may soon have to make the heart-wrenching choice of which patients get life-saving treatment and which ones will have to wait, Austrian media report. Intensive care units in the Salzburg region are packed, with the number of patients treated there setting a new grim record on Tuesday, reaching 33. The region ranks amid Austria’s hardest-hit, logging more than 1,500 new infections per 100,000 residents in a week. In an emotional plea for help to the local government, the head of Salzburg’s hospitals warned that soon clinics would likely not be able to guarantee the existing level of standards in terms of medical treatment. A representative for the city clinics likened the situation to “running into a wall.”
The region’s governor, Wilfried Haslauer, announced on Tuesday that some of the Covid patients whose condition was no longer life-threatening would be transferred from hospitals to rehabilitation centers to make room for more serious cases.
In neighboring Upper Austria, the situation is no better, with the number of deaths in intensive care units surpassing figures seen in all the previous Covid waves. Speaking to Austria’s Der Standard paper on condition of anonymity, healthcare workers there said they had free beds “because the infected are dying.”
For the time being, the creation of a so-called ‘triage team’ in Salzburg hospitals is being described as a “precautionary measure.” The panel is made up of six people: one legal expert and five providers from various medical disciplines. If push comes to shove, they will be deciding which patients stand a chance and which treatments have little prospect of success.
Rotterdam Mayor Ahmed Aboutaleb has described an anti-lockdown protest in his city as an “orgy of violence.” The Dutch demonstration devolved into a violent riot that saw police open fire on protesters.
Aboutaleb described the events of Friday night as an “orgy of violence,” after protesters packed Rotterdam’s central Coolsingel shopping street to voice their opposition to an ongoing partial lockdown, a ban on New Year’s Eve fireworks displays, and the possibility of a two-tiered system of freedom in the Netherlands, one of liberty for the vaccinated and restrictions for those without the jab.
The protest soon got out of hand, and police said on Saturday that 57 people were arrested. Protesters were seen torching police vehicles and launching fireworks at police, who shot at them in response.
Aboutaleb said that the cops had been “forced” to use their weapons. “On a number of occasions the police felt it necessary to draw their weapons to defend themselves,” he told reporters. “They shot at protesters, people were injured.”
Police say at least seven people were injured. Two of these injuries were caused by police bullets, and the victims are still in hospital. One officer was hospitalized, while several others were treated at the scene for minor injuries.
