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.

Amazon’s Bezos predicts only limited number of people will get to remain on Earth

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.

Libyan military commander Khalifa Haftar is set to challenge Gaddafi’s son for the top job, announcing his presidential bid. The election will take place on December 24.

I declare my candidacy for the presidential election, not because I am chasing power but because I want to lead our people towards glory, progress and prosperity,” the de facto leader of Eastern Libya said in a televised speech.

Haftar added that the election is the only way out of the severe crisis the country has been plunged into.

The announcement was expected; in September, Haftar announced that he was temporarily stepping down as head of the force known as the Libyan National Army, fulfilling the requirement for presidential hopefuls to suspend public work three months before an election.

Haftar will run against the son of former leader Muammar Gaddafi, Saif al-Islam Gaddafi, who represents the Popular Front for the Liberation of Libya.

Haftar’s presidential bid is likely to anger many who consider him a war criminal responsible for the indiscriminate killing of civilians during his military campaign. A number of civil lawsuits have been filed against him in a US federal court for alleged war crimes. Haftar has both US and Libyan citizenship, and owns property in Virginia.

Following years of civil war and political chaos after the NATO-backed intervention that saw Muammar Gaddafi deposed and brutally murdered, the upcoming election is widely viewed as an opportunity for political settlement and the long-awaited unification of the country, divided now between Haftar’s forces and the Tripoli-based Government of National Accord. However, there is still no consensus on the legal grounds for the election, which could become an obstacle for the peace process.

French President Emmanuel Macron has dismissed the possibility of locking down unvaccinated people in France, claiming the move would not be necessary because of the success of the Covid-19 ‘health pass’.

Speaking to La Voix du Nord newspaper in an interview published on Thursday, Macron said there was no need for France to follow Austria’s lead by locking down its unvaccinated citizens.

“Those countries locking down the non-vaccinated are those which have not put in place the [health] pass. Therefore, this step is not necessary in France,” Macron claimed.

The president’s health pass, which was the target of much criticism when it was introduced, requires people to provide proof of vaccination or a recent negative test before undertaking certain normal activities.  

The ‘Pass Sanitaire’ is required if citizens wish to go to restaurants, cafes, cultural venues, or cinemas. It’s also required to take long-distance trains, among other activities. 

Austria has led the way by starting a partial lockdown of the unvaccinated amid a surge in Covid-19 cases. The Czech Republic will follow suit next week, while Germany decided on Thursday to introduce similar measures in areas where Covid incident rates exceed the threshold.

Earlier in November, Macron made the continued use of the Covid health pass for over 65s dependent on getting a booster jab. 

Some 20,366 new infections were registered in the last 24-hour recording period. Case numbers have risen steeply in recent weeks.

This piece by General Joseph Votel (Ret.) and Lt. Gen. Michael K. Nagata (Ret.) and was first published by our friends at the Middle East Institute.


Lt. Gen. (ret.) Michael K. Nagata is a distinguished senior fellow on national security at MEI. He retired from the U.S. Army in 2019 after 38 years of active duty, with 34 years in US Special Operations. His final position was director of strategy for the National Counterterrorism Center from 2016 to 2019.

Gen. (ret.) Joseph L. Votel is a distinguished senior fellow on national security at MEI. He retired as a four-star general in the U.S. Army after a nearly 40-year career, during which he held a variety of commands in positions of leadership, including most recently as commander of CENTCOM from March 2016 to March 2019. 


OPINION – The United States and Pakistan have had a complex and often disappointing “love-hate” relationship since 1947 — one severely tested during the 20-year U.S.-led intervention in Afghanistan. We believe the time has come for serious policy consideration of whether and how both nations can achieve a more strategically beneficial and sustainable post-intervention relationship between the American and Pakistani governments and their populations.

As we consider a new policy, the U.S. military withdrawal from Afghanistan after two decades of leading the international coalition is almost complete. Early indications are that Afghanistan is increasingly likely to descend into significant instability and possibly serious fracture, which will have unwelcome consequences for the Afghan people and all of Afghanistan’s neighbors. It is already clear that international terrorist groups like al-Qaeda and Islamic State-Khorasan Province will continue to enjoy and probably grow their safe havens.

Whatever U.S. strategic concerns may be about the future of Afghanistan, the course and direction of Pakistan’s strategic choices in coming years will also matter to the United States. There are a variety of reasons for this.

First, Pakistan is a nuclear weapon state. Decades of investments in nuclear weapons by Pakistan and India, compounded by unrelenting and mutual historical, religious, cultural, and political antagonism between them, make this one of the world’s most dangerous flashpoints.

Second, all of the countries Pakistan borders are consequential for the U.S. Pakistan also has significant religious, cultural, and economic ties to other Muslim states such as Turkey and Saudi Arabia. In an era of “great power competition,” while Pakistan may not be one of the principal players, its network of relationships can be of strategic benefit to any of the great powers now involved, including the U.S. and China.

Third, despite its significant political and economic difficulties, Pakistan has a growing technology sector. Its youthful population and worldwide diaspora of Pakistani doctors, scientists, academics, and other professionals have become an increasingly important part of the global community.

As long-time veterans of South Asia, both of us understand the sources of “weariness and wariness” that U.S. policymakers, in both Democratic and Republican administrations, often associate with strategic discussions of Pakistan. We have both seen the U.S. government’s reluctance toward undertaking any kind of strategic interaction or rapprochement with Pakistan because of previous disappointments or perceived betrayals. Understanding the enormous complexities of Pakistan’s relationships, influence, and strategic choices in the South Asia milieu can be intellectually challenging and draining.

Yet, we have both concluded that the only thing harder than establishing a functional and mutually beneficial relationship with Pakistan is living without one. Given unstable borders, a nuclear standoff with India, the continued presence of terrorist organizations, and the high potential for all of this to further disrupt our interests, there is no better alternative.

Among those areas that we believe worth exploring with the Pakistanis are these:

First, the possibility of planning, along with other like-minded international actors (both state and non-state), to manage the consequences of significant political instability and human suffering emerging from Afghanistan, including the possibility of substantial refugee flight into Pakistan. Indeed, the Pakistanis have long and miserable memories of the surge of Afghan refugees after the Kabul government collapsed in the 1990s and have consistently expressed deep concerns about a possible repeat resulting from the U.S. withdrawal now nearing its completion.

Second, the possibility of counterterrorism cooperation against any terrorist threat that emerges from Afghanistan and prevents it from sowing further instability across the region. We do not consider it likely that Pakistan will allow any positioning of U.S. intelligence or counterterrorism elements within its borders. Still, there may be other ways (e.g., working groups, forums, or exchanges) to foster better cooperation if a threat emerges from Afghanistan that is of concern to our mutual interests.

Third, the possibility of enlisting Pakistan cooperation, and that of India, toward some type of partial de-escalation of tensions along their common border and, with it, even a slight amelioration of the nuclear weapons threat. It is instructive to recall that, before 9/11, Pakistani President Pervez Musharraf and Indian Prime Minister Atal Bihari Vajpayee initiated a dialogue about the de-escalation of tensions that included the highly emotional issue of Kashmir. However, talks broke down without significant agreement. While we recognize this is an extraordinarily complex and fraught issue for the U.S. to embrace, given all of its other strategic challenges, the specter of a potential nuclear conflict in South Asia should at a minimum prompt us to ask ourselves, “why not at least try?” Indeed, U.S. antagonists such as China would probably take a dim view of such efforts, and we believe that might be a reason for doing so rather than a reason to flinch from it.

We have long heard U.S. policy and operational practitioners cite phrases such as “never underestimate the Pakistanis’ ability to disappoint us.” But, unfortunately, most American policymakers do not understand how often we have heard the Pakistanis say the same thing about Americans. Thus, both sides have longstanding “neuralgias” about the other. As we end our Afghan campaign, now is the time to move beyond our neuralgias and carefully weigh the strategic costs of whether trying to somehow partner with Pakistan is more, or less, than the cost of failing to do so. We believe, in the long run, it is likely to be less costly.

Reuters has apologized for its poor choice of photo to illustrate a story about a monkey brain study that was deemed offensive and racist in China.

On Thursday, Reuters published a story titled “Monkey-brain study with link to China’s military roils top European university.” The report was about a Chinese professor studying how a monkey’s brain functions at extreme altitude.

The study was done with the help of Beijing’s People’s Liberation Army (PLA) with the aim of developing new drugs to prevent brain damage, Reuters said.

The news agency promoted the story on Twitter with a photo of smiling Chinese soldiers in an oxygen chamber.

The tweet prompted outrage in China, with people calling it racist on social media. Reuters responded on Friday night by deleting the original tweet because the photo of Chinese soldiers was unrelated to the story and “could have been read as offensive.”

“As soon as we became aware of our mistake, the tweet was deleted and corrected, and we apologize for the offense it caused,” Reuters said in a statement to the Global Times, China’s state-run newspaper.

It was not the first time the leading Western news agency had run into trouble in China. In July, the Chinese Embassy in Sri Lanka criticized Reuters for using a photo of Chinese weightlifter and Tokyo 2020 Olympics gold medalist Hou Zhihui that the country’s state media described as “ugly” and “disrespectful to the athlete.”

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.

‘Most vaccinated’ place on earth cancels Christmas

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.

Covid-19 variants keep emerging in different parts of the world, causing experts to ask how long the pandemic will last, and how effective the current methods of protection really are.

Since the pandemic started in 2019, people have referred to the disease which has paralyzed the world simply as ‘coronavirus’. Now, in 2021, when we talk about it, we mean not just the original variant, but also its numerous mutations.

Drastic drop in Covid vaccine effectiveness – study

In May, the WHO decided to label the key variants with Greek letters. Since then, the Delta variant has been proclaimed the predominant strain across the world, and now we have titles that look like codes to detail the differences between variants. Last month, the UK was put on high alert over a fast-spreading Delta AY.4.2 variant. This week, Norway reported finding one more version of the Delta strain – AY. 63. The country’s experts suggest it’s not more dangerous than the Delta mutation itself. Meanwhile, another Covid variant, discovered in France (B.1.640), brought the researchers an unpleasant surprise: they said they’d never seen mutations like it. 

Professor David Dockrell, from the Center for Inflammation Research of the University of Edinburgh, described to RT the reasons for the constant mutation of the coronavirus. “The areas in the virus that are most likely to change are those that come into contact with what we call ‘selective pressures’ – or factors that make them need to change,” he explains. “So, a version of the virus which mutates and changes to give it a selective advantage to escape from the immune system is more likely to prosper and become a dominant strain.” 

That’s how it works: The part of the virus many of the immune responses (or antibodies, T-cells etc.) are responding to is called the spike protein (or the S-protein). So, the virus tries to change it in order to survive. 

“We know that a variety of different viruses are able to mutate and change when exposed to the selective pressure of the immune system, whether it would be the human immune system or other species in which these viruses have evolved,” Prof. Dockrell says. “And of course, we’ve seen it most clearly with HIV, which is particularly good at changing and evolving. It does something called ‘reverse transcription’ – it copies material in the reversed direction from DNA to RNA.” 

Covid is still seemingly running faster than humanity’s efforts to curb it, but Prof. Dockrell has some good news. “The coronavirus – and viruses like it – are not as able to make these changes. They are going to do it to some extent, but they are not going to be as successful as retroviruses and HIV.” 

And the other major thing to say: When the viruses make changes, there’s always what we call ‘a fitness cost’. Many of the potential changes that the virus could make will actually not favor its survival. So there are only a certain number, potentially, of changes that the virus can make, before it starts affecting its fitness. 

Now, unfortunately, we are still in a phase where Covid19 can continue to evolve and change. It’s not time to panic, though, because across the world various ways to adapt the current anti-Covid strategies are already in place. First of all, people should keep getting vaccines – maybe receiving slightly altered booster doses, Prof. Dockrell suggests, “in a way, that we, after all, have to do with influenza, by providing a seasonal influenza vaccine and changing it every year.”

WHO sounds alarm over looming Covid-19 catastrophe in Europe

“And maybe we have to keep changing some of the treatments like these new monoclonal antibodies against the virus, because they also may be limited by the emergence of a mutation of the virus evolving the S-protein,” he adds. 

Sounds promising – but won’t it become a never-ending race against constantly emerging mutations? 

Hopefully not. According to Prof. Dockrell, there are parts of viruses that scientists call ‘conserved areas’. With time, vaccines and monoclonal antibodies will target these areas, which the virus finds very hard to change. “Clearly, the direction of travel is to develop either vaccine responses that affect more different kinds of virus, or these ‘monoclonal antibodies’ that we could use to prevent or treat infection, that they will target more conserved areas and therefore will be less limited by the ability of these virus to evolve and change,” he concludes.
