NASA’s DART mission is a success: the first step towards planetary asteroid defense

The DART project (Double Asteroid Redirection Test) is a NASA mission designed to measure how much a spacecraft can deflect an asteroid through an impact with a spacecraft. The mission started on 24 November 2021 with the launch of a spatial probe that crushed intentionally on 26 September 2022 into Dimorphos, a minor moon of the asteroid Didymos. Two days ago, on Tuesday October 11, NASA announced that Dimorphos' orbital period had shortened by 32 minutes - surpassing the "success threshold" by more than one minute. DART is the world’s first test of its kind: a step towards a defense system for our planet against potentially threatening asteroids coming from deep space. The project cost USD 330 million and took seven years to develop. The results obtained justify further efforts toward testing and improving asteroid deflection methods. However, in order to sufficiently displace a bigger asteroid representing a threat to Earth, it is necessary to act with ample margin. It would mean identifying threats months if not years in advance, which implies having a global and connected surveillance network. A planetary defense system designed to prevent a potential doomsday meteorite collision with Earth. Something possible only with full collaboration among nations, rather than a fragmented politics of nationalistic interests. Is the world ready to protect itself from asteroids?

Russias attacks Ukraine’s energy infrastructures as western countries work to unite their front

The Ukraine crisis is reaching new levels just ten days after the annexation of 15% territory to Russia. While the Kremlin declared that the annexed territories are part of Russia forever, Ukraine president Zelenski indicated that they intend to free the whole country from the invasion, Crimea included. In the last few days, the Ukrainian army has obtained some results by gaining back small portions of the subtracted regions. In a successful operation, a crucial bridge connecting Crimea and Russia was hit and temporarily put out of order. However, the answer from Russia has been serious with more than 100 cruise missiles dropped on key objectives, including Kyiv and Leopoli. The attacks, where energy infrastructures were targeted, resulted in many deaths and blackouts throughout the country. On the international front president of Belarus Lukashenko announced a plan to deploy joint forces with Russia. The EU leaders and allied countries met in Prague on October 7 to consolidate a community of 44 countries ready to contrast Russia on all fronts. Today October 11, during an emergency meeting of the G7 nations in Berlin, the leaders committed to supporting Ukraine for "as long as it takes" while promising to continue to provide financial, humanitarian, military, diplomatic, and legal support. Further, an air shield will be implemented to neutralize the Russian missiles and drones. More sanctions against Russia have also been planned. All this is happening in a tense diplomatic climate. While Russian officials have recently threatened the use of tactical nuclear weapons, US president Joe Biden said that “we have not faced the prospect of Armageddon since Kennedy and the Cuban Missile Crisis”.

The Nobel Prize in Economic Sciences 2022 goes to the analysis of banks role during financial crisis

Ben Bernanke (USA, 68), Douglas Diamond (DK, 68), and Philip Dybvig (USA, 67) are the winners of the Nobel Prize in Economic Sciences 2022, awarded “for research on banks and financial crises”. Their research shed light on the significant role of banks in the economy, particularly during financial crises. An important finding in their research is why avoiding bank collapses is vital to avoid escalating consequences during crises. They have analyzed in detail the weakness of banks when rumors of imminent collapse spread: If a large number of savers simultaneously run to the bank to withdraw their money, the rumor may become a self-fulfilling prophecy – a bank run occurs and the bank collapses. These dangerous dynamics can be prevented through the government providing deposit insurance and acting as a lender of last resort to banks. Ben Bernanke analyzed the Great Depression of the 1930s, the worst economic crisis in modern history. Among other things, he showed how bank runs were a decisive factor in the crisis becoming so deep and prolonged. When the banks collapsed, valuable information about borrowers was lost and could not be recreated quickly. Overall, their work was crucial for the implementation of the modern defense mechanisms enacted during the financial crisis.

The 2022 Nobel Peace Prize assigned for protection of civil and human rights in East Europe

The 2022 Peace Prize is awarded to human rights advocate Ales Bialiatski (60 - Belarus), the Russian Human Rights Organization Memorial, and the Ukrainian human rights organization Center for Civil Liberties. The laureates "have for many years promoted the right to criticize power and protect the fundamental rights of citizens. They have made an outstanding effort to document war crimes, human rights abuses, and the abuse of power. Together they demonstrate the significance of civil society for peace and democracy". The Memorial has been founded in 1989 to commemorate the crimes committed under Joseph Stalin's reign in the Soviet Union, and it was based in Moscow until its forced dissolution in 2022 for violations of "foreign agent law". The Center of Civil Liberties was founded in Kyiv in 2007. The organization is engaged in an attempt to make Ukraine more democratic and to improve the public control of law enforcement agencies and the judiciary. It also documented war crimes during the ongoing invasion of Russia in Ukraine. Ales Bialiatski is known for his work with the Viasna Human Rights Centre, based in Minsk until Belarus ordered its closure in 2003. This was an organization providing assistance to political prisoners. In 2010 controversial presidential elections were held and both Visa's offices and Bialiatski's home have been searched by state security forces repeatedly. Bialatski was summoned in the same year to the Public Prosecutor's office and warned that as Viasna was an unregistered organization, the government would seek criminal proceedings against it if the group continued to operate. More recently, following the Belarusian protests in 2020-2021, Viasna's members have been further prosecuted with politically motivated charges. Ales Bialiatski, now Nobel Peace Laureate, has been imprisoned Since 14 July 2021 for alleged tax evasion. Human rights defenders consider him a prisoner of conscience.

Annie Ernaux wins the 2022 Nobel Prize in Literature

The 2022 Nobel Prize in Literature was awarded to the french author Annie Ernaux “for the courage and clinical acuity with which she uncovers the roots, estrangements and collective restraints of personal memory”. Annie grew up in Normandy in a working-class family. She started her literary career in 1974 with Les Armoires Vides ("Cleaned Out"), an autobiographical novel. Very early in her career, she turned away from fiction to focus on autobiography, combining historic and individual experiences. Her books are followed by a wide readership and are reviewed in most local and national newspapers in France, as well as being the subject of many radio and television interviews and programs, and a large and growing international academic literature. Her famous works include La Place ("A Man's Place", 1983), L'événement ("Happening", 2000), L'Occupation ("The Possession", 2002), and Les Années ("The Years", 2008). Ernaux has always been adamant that she writes fiction. Many of her works have been translated into English, and she was nominated for the International Booker prize in 2019 for her book The Years. Her work is published in the US by Seven Stories Press. Ernaux is one of the seven founding authors from whom the press takes its name.

Bertozzi, Meldal, Barry: the 2022 Nobel Prize in Chemistry awarded to the pioneers of “click” chemistry

Carolyn R. Bertozzi (USA, 55), Morten Meldal (DK, 68), and Barry Sharpless (USA, 81) are the winners of the Nobel Prize in Chemistry 2022, awarded “or the development of click chemistry and bioorthogonal chemistry”. Sharpless and Meldal have laid the foundation by describing the process for the first time in two independent but very similar works. Bertozzi (the 8th woman in history awarded with this Nobel) has taken click chemistry to a new dimension and started utilizing it in living organisms. Click chemistry is not a single specific reaction but describes a way of generating products by joining small modular units. By the union of biomolecules and molecular probes, they have been made notably useful in the detection, localization, and qualification of biomolecules in vivo. However, the method is not limited to biological conditions: the concept of a "click" reaction has been used in chemoproteomic, pharmacological, and various biomimetic applications. The reason for such widespread use is that these reactions are in general able to occur in relatively simple conditions, are not disturbed by water, generate little and inoffensive byproducts, and happen quickly with high characteristic yield. These qualities make click reactions particularly suitable to the problem of isolating and targeting molecules in complex biological environments. In such environments, products accordingly need to be physiologically stable and any byproducts need to be non-toxic (for in vivo systems). Their work finds even further application in all those industries and research fields where molecules need precision design and production, such as nanotechnology, pharmacology, and materials engineering.

Aspect, Clauser, Zeilinger: the Nobel prize in Physics goes to experimental quantum entanglement

A famous law of quantum mechanics states that two objects that are separate in space can, in some cases, maintain a strong connection: what happens to one object will immediately influence the other. Such incredible behavior, referred to as entanglement, is a characteristic of quantum mechanics which has no parallel in classical physics. If theories have been developed at the beginning of the past century, the experimental proof came much later. It is for their pioneering experiments that demonstrate these facts that today Alain Aspect (France - 75), John F Clauser (the USA - 79), and Anton Zeilinger (Austria - 77) are the winners of the 2022 Nobel Prize in Physics. Thanks to their work, quantum entanglement is not just a theory anymore, but rather a hard undeniable fact of nature. It is also thanks to their contribution that today many investments have been dedicated to quantum technology, which is revolutionizing the capabilities of our computers as well as bringing cybersecurity to the next level.

Swedish paleogeneticist Svante Pääbo wins 2022 Nobel Prize for Physiology or Medicine

Dr. Svante Pääbo (Swedish - 67), founder of the Max Planck Institute for Evolutionary Anthropology in Germany and adjunct professor at the Okinawa Institute of Science and Technology, won the 2022 Nobel Prize for Physiology or Medicine. His most important contribution to science was the sequencing of the genome of the Neanderthal, an extinct relative of present-day humans. Dr. Pääbo and his team found that the modern human - Homo Sapiens - inherited some genes from these now exinct hominis. This ancient flow of genes to present-day humans has physiological relevance today, for example affecting how our immune system reacts to infections. The anatomically modern human - Homo Sapiens - first appeared in Africa approximately 300,000 years ago, while our closest known relatives - Neanderthals - developed outside Africa and populated Europe and Western Asia from around 400,000 years until 30,000 years ago, at which point they went extinct. About 70,000 years ago, groups of Homo Sapiens migrated from Africa to the Middle East and from there they spread to the rest of the world. Homo sapiens and Neanderthals thus coexisted in large parts of Eurasia for tens of thousands of years. The research of Dr. Pääbo has proven that such coexistence may have been closer than previously thought.
