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.

French luxury giant Dior has taken down a controversial photograph that had been criticized in China for “smearing Asian women” by pandering to Western stereotypes while “distorting Chinese culture.”
The photo, which was part of the brand’s ‘Lady Dior’ exhibition in Shanghai, depicts an Asian model wearing a traditional dress and clutching a Dior handbag. It came under fire this week from Chinese media outlets for featuring “spooky eyes, [a] gloomy face and Qing Dynasty-styled nail armor.”
Although Dior has not released a statement regarding the controversy, it confirmed to fashion trade publication Business of Fashion that the photo had been removed from the exhibition. The brand has also reportedly taken the photo off Chinese social media platform Weibo.
The image, which was shot by Chinese photographer Chen Man, had drawn both media ire and public outrage. However, there were apparently no calls for a boycott of the brand.
In an editorial on Monday titled “Is This the Asian Woman in Dior’s Eyes?”, the Beijing Daily paper had noted that the image makes Chinese consumers uncomfortable. The publication criticized Man for “playing up to the brands, or the aesthetic tastes of the Western world.”
For years, Asian women have always appeared with small eyes and freckles from the Western perspective, but the Chinese way to appreciate art and beauty can’t be distorted by that.
Warning that both the brand and the photographer had “gone too far,” the China Women’s News paper ran an editorial on Wednesday that claimed it “indicated their intention of uglifying Chinese women and distorting Chinese culture.”
“Again, from… Dior’s ghost-style picture, which makes the public feel uncomfortable, it’s easy to see some Western brands’ ‘pride and prejudice’ in their aesthetics and culture,” said the newspaper, which is run by the All-China Women’s Federation.
Meanwhile, the Global Times noted that the “lingering controversy could pose a delicate situation” for Dior and other global brands – for whom China’s “massive” luxury market was one of the biggest sources of revenue. The paper said that the Chinese public had become “increasingly sensitive” toward the depiction and treatment of Chinese people and culture by foreign companies.
While pointing out that Chinese social media users had demanded the company and photographer explain their intention, a number of media outlets also highlighted how some netizens had praised the photo as a departure from typical standards of beauty in the country, often characterized by “fair skin and large eyes.”
Czechia will prohibit people who have not been vaccinated from entering public spaces such as restaurants and shops from Monday. Negative Covid-19 tests will no longer be allowed.
Speaking on Wednesday, outgoing Prime Minister Andrej Babis said the country would adopt the so-called Bavarian model from Monday next week, prohibiting those who have not received a Covid-19 vaccine from entering public places. Those who have recently recovered from the virus will be allowed entry.
The country will enter a partial lockdown of the unvaccinated from Monday morning, assuming the restrictions are approved by the cabinet on Thursday.
“We will introduce the Bavarian model from Sunday to Monday. This means that entry to restaurants, service establishments, or mass events will only be allowed for vaccinated or survivors. Those vaccinated with a single dose must have a PCR test,” Babis said on local TV.
The prime minister said that self-testing would be completely cancelled, as he lamented unvaccinated people for clogging up hospitals and preventing treatment reaching those with other illnesses.
“The death toll is rising; the situation is serious. Vaccination is the only solution, there is no other,” he added.
The country is seeing a spike in infections, with a record 22,479 new cases reported on Tuesday.
The Bavarian model refers to strict anti-Covid measures introduced in the southern German state. Markus Soder, the state’s premier, claimed there was no choice but to implement “a kind of lockdown for the unvaccinated,” citing increasing pressure on hospitals and medical staff.
Meanwhile, some two million people in Austria who are yet to receive their Covid shots have been subject to the world’s first lockdown for the unvaccinated, in an effort to bring case numbers down.
While 68% of people are vaccinated in Germany, and 65% in Austria, just over 60% are vaccinated in the Czech Republic.
Austria will introduce a full lockdown that could last for three weeks on Monday in an attempt to tackle a new wave of Covid-19 infections. The government has also ordered the entire population to get vaccinated from February 1.
On Friday, conservative Chancellor Alexander Schallenberg told a news conference that a complete lockdown of the nation would begin on Monday and last for an initial 10 days.
He stated that the restrictions could be extended if infection rates did not start to fall, but he insisted the lockdown would not exceed 20 days.
The measures concern the entire Austrian population. The government has already imposed a partial lockdown on the unvaccinated in an effort to reduce hospitalization rates amid a surge in Covid-19 cases.
When the full lockdown ends, restrictions will remain in place for the unvaccinated.
Schallenberg’s announcement came after a meeting of nine state governors, two of whom had already vowed to introduce full lockdowns in their regions on Monday, in the western province of Tyrol.
The chancellor also announced that vaccinations would be mandatory from February 1. “We haven’t been able to convince enough people to vaccinate. For too long, I and others have assumed that you can convince people to get vaccinated,” he added, giving his rationale for the mandate.
Schallenberg said he lamented the political forces, radical opposition, and fake news fighting against vaccination.
Austria has one of the lowest vaccination rates in western Europe, with only 65% inoculated against the deadly virus according to data from Johns Hopkins university.
Infection rates are almost among the highest on the continent. The seven-day incidence rate stands at 971.5 per 100,000 people.
