The consumption of ginger may have a beneficial effect against bacterial infections

Ginger is a flowering plant whose root is used as a spice and herbal remedy. It's native to Southeast Asia but is now cultivated in many other parts of the world, including India, China, and the Caribbean. Ginger is a versatile and flavorful ingredient with a long history of culinary and medical use. It has a spicy, savoury flavour and warming quality, making it a popular ingredient in many cuisines, especially in Asian and Indian dishes. It's often used in teas, soups, curries, and desserts.

Beyond its culinary uses, ginger has been used for its medicinal properties for thousands of years. It's believed to have anti-inflammatory, antioxidant, and anti-nausea effects, among other health benefits. Some people use ginger to alleviate symptoms of conditions such as nausea, vomiting, arthritis, and menstrual cramps. Ginger is becoming increasingly popular in Germany as a medicinal plant or as food. According to the German Federal Statistical Office, the annual import volume of the fruity-hot root has almost quadrupled over the last ten years to around 31,600 tons.

A team led by Veronika Somoza, director of the Leibniz Institute in Freising, Germany, conducted extensive research to clarify if normal ginger consumption levels are sufficient to achieve health effects. The starting point was a result of a pilot study which showed significant amounts of aromatic ginger compounds enter the blood about 30 to 60 minutes after consuming one litre of ginger tea. The study results suggest that ginger stimulates the functionality of our immune system. Small amounts of an aromatic ginger constituent in laboratory tests put specific immune cells - white blood cells - on heightened alert. These cells are mainly involved in the protection against bacterial infection. The study also shows that this process consists of a type of receptor that plays a role in the perception of painful heat stimuli and the sensation of spiciness in food. Although more research is needed to understand its full potential for therapeutic applications, it is now demonstrated that the typical ginger intake may benefit our immune system's functionality, particularly against bacterial infection. Nevertheless, many unanswered questions at the epidemiological and medical levels still need to be addressed.

Could bacteria and viruses trigger Alzheimer’s disease?

Alzheimer's is a neurodegenerative disorder characterized by a progressive loss of memory and cognitive function, along with changes in behaviour and personality. It is the most common form of dementia, affecting millions of people worldwide, and is typically diagnosed in individuals over 65. However, early-onset forms of the disease can occur in younger individuals. Alzheimer's is caused by the accumulation of abnormal protein deposits in the brain, which can interfere with communication between brain cells and ultimately lead to their death. While the major hallmarks of Alzheimer's are well-known, we still have little idea what triggers it. Specific genes and lifestyle factors such as loneliness, lack of exercise and poor diet can all increase the risk of Alzheimer's, but how and why it begins remains a mystery.

Since the mid-80s, a handful of scientists worldwide have doggedly pursued the idea that either a virus or a bacterium could play a role in Alzheimer's. Studies show that people with herpes are more likely to get Alzheimer's. In particular, evidence pointed towards herpes simplex virus 1 (HSV-1) – a pathogen found in 70% of the UK population and the cause of oral herpes. When Prof Ruth Itzhaki from Oxford University's Institute of Population Ageing – who has done more than any other scientist to advance the HSV-1 theory of Alzheimer's - examined post-mortem brain samples from patients, she found more significant amounts of the virus's DNA than in people who had not died of the disease. Moreover, other studies show that treatment with a standard antiviral drug decreased the risk of dementia ninefold. Others have suggested that bacteria may also be capable of initiating the neurodegeneration that leads to Alzheimer's. Chlamydia pneumonia, which causes lung disease, and Borrelia burgdorferi, associated with Lyme disease and gum infections, have all been put forward as possible triggers. The main reason viruses like HSV-1 and possibly bacteria may be capable of triggering Alzheimer's is that they invade the body before burrowing into the central nervous system and travelling to the brain sometime in midlife. Once there, they stay dormant for many years before being reactivated in old age, either because the ageing immune system can no longer keep them in check or something else – a traumatic episode, a head injury or perhaps another infection – spurs them to life. Once awakened – so the theory goes – they begin to wreak havoc. Davangere Devanand, a neurologist at Columbia University Medical Center, is running a clinical trial investigating whether a herpes antiviral drug called valacyclovir could slow the progression of Alzheimer's in patients in the early stages of the disease. The ongoing trial, expected to be completed by early 2024, could significantly affect how we view the condition.

Ukraine crisis update: US and EU aim to further intense confrontation, while China proposes to mediate

The tensions between the European Union and Russia have grown over the Ukraine war in the last two months. The Ukraine crisis has yet to have a favourable negotiation in sight today. On January 23, after weeks of Poland and other NATO members openly pressuring Germany to permit the dispatch of Leopard 2 tanks to Ukraine, the US and EU allies decided to send armour. With this decision, NATO demonstrated continued assistance to Ukraine despite this meant crossing what was previously called Russia's "red lines". In the following days, Russian Security Council Deputy Chairman Dmitry Medvedev reiterated in a written interview that the Russian response to attacks in Russian territory can be of any nature and that these will be consistent and immediate - referencing the country's nuclear arsenal.

Additionally, on February 2, EU President Ursula Von Der Leyen visited Kyiv along with 15 European Commissioners. The meeting discussed the numerous reforms needed for Ukraine to achieve EU membership. President Von Der Leyen also confirmed support in funds for 1 billion and further sanctions against Russia to be enacted by the end of the month. On February 8, Ukrainian President Volodymyr Zelensky visited London and urged the allies to send combat aircraft. He obtained more support in training Ukraine pilots, which may be a premise for effectively using NATO's jets. Zelensky travelled to Paris in the evening, following his visit to the United Kingdom, to meet France's leader Emmanuel Macron and German Chancellor Olaf Scholz. On February 9, he met in Brussels with European Union leaders as they gathered for a summit. "A Ukraine winning is going to be a member of the European Union," Zelenskyy said. The Ukrainian president's main messages in London, Paris and Brussels were pleas for long-range missiles and fighter jets to beef up his armed forces and (to the EU) the necessity of rapid entry into the bloc. Following these visits, the European Parliament voted with a large majority and heavy resolution on February 15, condemning Russia's invasion and annexation of Ukraine's territories. In the document, the EU reiterates its support for Ukraine's independence, sovereignty and territorial integrity, stating that the outcome of the war and the stance taken by the international community will play a crucial role in affecting future action by other authoritarian regimes. Besides demanding that Russia withdraws its troops, it confirmed a steady and continued increase in the supply of all types of weapons to Ukraine, without exceptions, mentioning for the first the possibility of sending fighter jets and missile systems. Additionally, more sanctions against Russia will be put in place by the end of February, and a legal frame to confiscate frozen Russian assets - is to be devolved to Ukraine's reconstruction.

Following the Plenary at the EU Parliament, a Security Conference of the G7 took place in Munich on February 17 and 18. For the first time since the outbreak of COVID, China was represented in Munich at a high level this year in the form of its most senior diplomat, former Foreign Minister Wang Yi. Wang told the audience that China had tried and would continue to try to broker Ukraine peace talks. "There were multiple rounds of peace talks. And we saw a framework text on the peaceful resolution of the crisis. However, that was stopped. We do not know why. The process was cut short. Some forces might not want to see peace talks materialize. They don't care about the life and death of Ukrainians, not the harm to Europe. They might have strategic goals larger than Ukraine itself." Wang also used the war in Ukraine as an opportunity to say that "for a safer world, the sovereignty and territorial integrity of all countries must be respected". In his introductory remarks, Wang had said that COVID had shown how the world was "one global village" and could only "win the victory when we trust each other." However, the US, German, and French representatives expressed perplexity about finding a diplomatic solution in the immediate future. In its final statement, the G7 confirms support for Ukraine until necessary and condemns Russia's actions. Today February 20, two more critical meetings took place. US president Joe Biden met Volodymyr Zelensky during a surprise visit to Kyiv, where he promised increased arms deliveries. In the meantime, Chinese Minister Wang Yi visits Moscow to meet with Vladimir Putin.

New methods are emerging to harness the full potential of quantum computing

Quantum computing is a relatively new field that seeks to harness quantum mechanics' strange properties to perform computations beyond the reach of classical computers. It is a type of computer that uses the principles of quantum mechanics to perform calculations. Unlike classical computers, which use bits that can be either 0 or 1, quantum computers use quantum bits or qubits, which can be in a state of 0, 1, or both at the same time (known as a superposition). Qubits allow quantum computers to perform certain types of calculations much faster than classical computers. One of the main reasons why quantum computing is so important is that it has the potential to revolutionize computing and solve some of the world's most complex problems. For example, quantum computers are particularly good at solving specific optimization problems difficult for classical computers, which could have applications in logistics, finance, and transportation. Quantum computers are also well-suited to simulating the behaviour of other quantum systems, which is difficult for classical computers. This could have applications in fields like materials science, where researchers are interested in simulating the behaviour of complex molecules and materials. In addition, quantum computers could accelerate the training of machine learning algorithms, leading to more powerful AI systems. And while they can break many of the encryption methods currently used to secure online communications, they can also create new encryption methods that are even more secure.

Despite these exciting possibilities, quantum computing is still in the early stages of development, and many issues must be overcome before it can reach its full potential. The main technical challenges of quantum computers today include the need for error correction to improve the reliability of computations, the development of more powerful quantum hardware, the ability to control and scale up the number of qubits, and the ability to implement fault-tolerant quantum operations. For these reasons researchers worldwide are working to build more robust and reliable quantum computers, and the field is advancing rapidly. On February 8, a team from the University of Sussex led by Prof Winfried Hensinger published a method to transfer quantum information between computer chips at record speeds and accuracy. According to Prof Winfried Hensinger, who led the research at Sussex University, the new development paves the way for systems that can solve complex real-world problems that the best computers we have today are incapable of.

While physicist Richard Feynman first proposed the idea of a quantum computer in the 1980s, it was in the late 1990s that the first functional quantum computers were built. The first quantum computer was created by a team of researchers at the Los Alamos National Laboratory in 1998. This early quantum computer could only perform simple calculations and was mainly used for proof-of-concept experiments rather than practical applications. However, it demonstrated that quantum computing was a viable field of research, and subsequent developments in the area have led to the creation of more powerful and sophisticated quantum computers. While quantum computers are still in their early stages of development and many technical challenges remain, they represent a promising new direction in computing that has the potential to revolutionize many fields. As such, they are an area of intense research and investment, with companies and governments worldwide working to develop and deploy quantum computers in the years to come.

Historic decision of the European Union imposes phase-out of gasoline and diesel vehicles by 2035

Diesel and gasoline cars are significant contributors to greenhouse gas emissions. In 2018, the transportation sector, which includes cars, trucks, and other vehicles, accounted for approximately 28% of total greenhouse gas emissions in the United States. Of this 28%, passenger cars and light-duty trucks (which include gasoline and diesel vehicles) were responsible for about 60%. The primary factor contributing to the release of greenhouse gases from gasoline and diesel vehicles is the combustion of fossil fuels in their engines. When gasoline or diesel is burned, carbon dioxide, a potent greenhouse gas, is released into the atmosphere. Other factors that contribute to vehicle emissions include fuel production and transportation, vehicle manufacturing, and vehicle maintenance. For these reasons, efforts are being made to develop and promote alternative fuel vehicles, such as electric and hydrogen fuel cell vehicles.

Today February 14, the European Union is the first political entity to take a strong position by introducing a controlled phase-out of all gasoline and diesel vehicles. Despite the right-wing parties' opposition, the final ok by the Parliament was reached with 340 votes in favour, 279 against and 21 abstentions. The new legislation is part of the Fit for 55 packages. It establishes a concrete path towards zeroing CO2 emissions: the objectives are to reduce cars' emissions by 55% in 2030 and 100% in 2035 compared to 2021 levels. After that, the new cars and vans will no longer have to produce any CO2 emissions. The decision comes as a fundamental step in order not to further aggravate the crisis linked to climate change which, by 2035, could lead to devastating consequences on a global level. Parties that opposed the decision are already proposing amendments, such as a request to postpone the phase-out deadline by a few years. Such a minor adjustment will be possible in the next few months, after which the decision will be final.

Many politicians still consider the agreement dangerous and harmful for the automotive and other sectors of the economy. The arguments revolve around both the investments needed by the automotive industries to adapt as well as the implicit dependence by third countries supplies that this strategic choice imposes. In particular, minerals such as cobalt and lithium are mainly sourced from extra-EU countries. The EU imports a significant amount of lithium and cobalt, critical raw materials used to produce batteries for electric vehicles and energy storage systems. According to the European Commission, most of the world's cobalt production comes from the Democratic Republic of Congo (DRC). Lithium is mainly produced in South America, particularly in Chile. In 2020, the EU imported approximately 48,000 metric tons of cobalt and 26,000 metric tons of lithium, according to the European Commission. These imports represent a significant portion of the EU's total demand for these materials. The EU currently has limited domestic production capacity for these critical raw materials. The EU is working to develop a sustainable and responsible supply chain to reduce its dependence on imports, including promoting the development of domestic production capacity, supporting the recycling and reuse of these materials, and working with partner countries to promote sustainable and responsible mining practices.
