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.

CIPHER BRIEF EXPERT PERSPECTIVE 

Cipher Brief Expert Tim Willasey-Wilsey served for over 27 years in the British Foreign and Commonwealth Office. He is now Visiting Professor of War Studies at King’s College, London.

Older Americans have Saigon 1975 and the helicopters from the Embassy roof seared into their memories. A previous generation of Britons was haunted by the image of General Percival surrendering vast numbers of troops and equipment in Singapore to the Japanese in 1942. How Kabul falls to the Taliban could have important practical and symbolic significance.

The announcement that the United States is sending 3,000 troops to Kabul alongside 600 British troops to manage the evacuation of their civilians and those Afghans who provided assistance, is a remarkably late response to a rapidly deteriorating situation. Unless carried out in the next 48 hours, it will also be risky. Taliban infiltrators are already inside Kabul and the forces which captured Ghazni and Kandahar on 12th August will be heading towards the capital on their Honda 125cc motorbikes.

The US must have extracted undertakings from the Taliban negotiators in Qatar not to launch their full assault on Kabul until the evacuations are complete, but elements of doubt remain. Previous Taliban assurances have proved worthless, and it is doubtful that individual Taliban commanders would wish to hold back while some of Ashraf Ghani’s ministers, senior army officers, judges and officials are spirited away to a life of exile.

It is hard not to be impressed by the speed and élan of the Taliban’s recent successes; taking 13 of Afghanistan’s 34 regional capitals in almost as many days. It is reminiscent of the extraordinary progress which the Japanese made down the Malaya Peninsula in 1942 with Singapore as the ultimate prize.

The Taliban’s success has not happened by chance. It is clearly the fruit of preparation and planning. Above all, they have learnt from the experience of 1994 to 1996 when they eventually took Kabul but failed to capture the north, thereby allowing space for the Northern Alliance parties to survive and then reassert themselves following the 9/11 terrorist attacks.

This time, the Taliban have focussed first on border posts with neighbouring countries (thereby denying the government vital supply routes and customs revenues) before taking outlying regional capitals and leaving Kabul (which is never easy to capture) until last. Above all, they have concentrated on the north where many rural Afghans are disenchanted with the Kabul government and regional warlords. The north is no longer the solid bastion of anti-Taliban sentiment it was in the 1990s.

Taliban progress in the north has snuffed out any chance that the old Northern Alliance could be reborn out of the eventual collapse of the Ashraf Ghani government. Whereas in 1996, Ahmed Shah Massoud, its brilliant military leader, was able to abandon Kabul and beat a tactical retreat up the Panjshir Valley, that option barely exists today. Not only is Massoud dead but his former adherents are no longer guerrilla fighters but members of a stratified Afghan army which has struggled to perform without US air support.

The Taliban have also ruthlessly exploited the weak negotiating stance of the United States and its chief negotiator Zalmay Khalilzad. Whereas some of the Taliban team in Doha, such as Mullah Barader, may indeed have been ‘moderates’ there was never any doubt that the Taliban movement wanted to see the total defeat of the Kabul government and the expulsion of Western forces. Pakistan too, may have occasionally considered some form of negotiated deal but ultimately the only sure way of keeping Indian influence out of Afghanistan (it believes) is a Taliban government.

The Afghan army (and in particular its impressive Special Forces) will now be assembling in Kabul and should be able to repel initial attempts to overrun the city. Certainly, Gulbuddin Hekmatyar found it impossible to take Kabul in 1992 and 1993 even with help from Pakistan, which, in frustration, switched support to the newly-created Taliban movement in late 1994.

But from 1992 to 1996 there were frequent deliveries of supplies to Massoud and his Northern Alliance defenders from Russia, Iran, and India. In 2021, the position is very different. Russia has already decided to “back the winner” and believes it has extracted promises from the Taliban not to export Islamism northwards into the Central Asian Republics (CARs). Iran too has channels to the Taliban and will be watching carefully for any return to the Taliban’s persecution of the Shia Hazaras. And India has already made contact with the Taliban in Doha in the hope that the Taliban in power will prevent Kashmiri militant groups from setting up bases there.

The likelihood therefore is that Kabul will fall to the Taliban quite quickly. If the Americans and British do manage to insert their evacuation forces soon, they should be able to complete the operation successfully, although there are likely to be heart-rending scenes at the airport as crowds of refugees are turned away at gunpoint from departing aircraft. Regional powers, particularly Pakistan, will try and persuade the Taliban to hold back from intervening, conscious that a bloodbath in Kabul would be a disastrous start to the Taliban’s second spell in government. Ironically, however, the evacuation would almost certainly lead to the collapse of the Kabul government as senior officials are forced to decide whether to take the last aircraft out or face almost certain torture and death at the hands of the victors. It is doubtful whether any Western countries will choose to retain their embassies in Kabul. For President Biden, the memory of Benghazi will be too raw.

What is certain is that there will be new iconic images to rival those of Saigon and Singapore.

The city council in Austria’s second-largest city, Graz, has elected a new mayor. Communist Party member Elke Kahr has become the first Communist leader of a major city in the country.

The 60-year-old politician, who has been working in the municipal government for more than 15 years and previously served as vice mayor of Graz, was elected as the new city leader on Wednesday. A member of the Austrian Communist Party (KPÖ, Kommunistische Partei Österreichs) for almost 30 years, she won the election with 28 of 46 votes. Kahr succeeded the previous long-standing mayor Siegfried Nagl of the center-right, liberal-conservative People’s Party.

Who would have thought that the daughter of a locksmith, a Communist, would become mayor,” she said in her first speech following the vote.

Having acknowledged a number of issues to deal with in the city, especially during the Covid-19 pandemic, the new mayor highlighted a housing policy, pledging to put a stop to profit-driven construction in Ganz.

The Communists have also already formed a coalition with the Greens and the Social Democratic Party (SPÖ), and another precedent in European city governance was made – two women serving as mayor and deputy. Green leader Judith Schwentner was chosen as Graz’s vice mayor, with the new governing coalition saying they would support not only social, but also environmental changes, aiming to improve living standards especially for low-income groups. Providing a bicycle for every child in the city from the municipality is in their program.

However, not everyone in the local government is happy with the new Communist rule. A member of the right-wing Freedom Party of Austria (FPÖ), Alexis Pascuttini, described the choice as “unpleasant,” having accused the Graz Communists of empty catchphrases in their program and refusing to participate in what he described as “left-wing nonsense.” Kahr herself has been exposed to strong pressure to justify her party, being repeatedly asked about her position on “the crimes of communist parties around the world since 1917,” according to Austrian media.

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 may buy Russian S-500 anti-space-weapon defense system in world-first arms deal, despite risk of US sanctions, Moscow claims

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.

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.”

German media reveals jail terms for fake Covid 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.
