US midterm elections are over: Democrats control the Senate, Republicans control the House, and Trump launches his third campaign for Presidency

On December 6, the 2022 midterm elections officially concluded after the vote in Georgia. The final result is 51/49 Senate seats for the Democrats and 222/213 in favour of the Republicans in the House. Nearly a month ago, after the vote in Nevada, it was already clear that the Democrats had control on at least 50% of the Senate seats, meaning a majority thanks to the power of casting vote of the Vice President (now Kamala Harris, a Democrat). The voice in Georgia, however, is significant as the Democrats won a crucial seat that allows them to keep the majority in the Senate even if a Republican vice president takes over in the next presidential elections. While victory in the Senate is undoubtedly important, the situation changed in the opposite direction in the House of Representatives. The Republicans had won control of the US House already on November 16, returning the party to power in Washington and giving conservatives leverage to blunt President Joe Biden's agenda and spur a flurry of investigations. Just one day after retaking a majority in the US House of Representatives, Republicans have said they will investigate the president's family as a "top priority". The lawmakers said the inquiry would focus on the overseas business dealings of the president's son, Hunter Biden. The 52-year-old is already under federal investigation but has not faced any charges. The younger Biden is not involved with the administration in any capacity. But top Republicans insist their inquiry will determine the extent of Joe Biden's alleged involvement in his son's business dealings, including during the elder Biden's time as vice president. This situation will complicate the ability to govern both parties during and after the ongoing presidential mandate. However, the results are more favourable than predicted for the Democrats, as Republicans hoped to entirely reset the agenda by capitalizing on economic challenges and Biden's lagging popularity. Despite a worse-than-predicted outcome, former President Donald Trump launched on November 15 his third campaign for the White House: "To make America great and glorious again, I am tonight announcing my candidacy for president of the United States," Trump said before an audience of several hundred supporters in a chandeliered ballroom at his Mar-a-Lago club, "America's comeback starts right now," he said, formally beginning the 2024 Republican primary. It is worth noting that Trump was the first president to be impeached twice, and his supporters violently stormed the Capitol during the transition of power on January 6, 2021. But the campaign of Donald Trump has to face more than "just" the proof of ballots. Recently, on December 7, a Manhattan jury found two Trump Organization companies guilty on multiple charges of criminal tax fraud and falsifying business records connected to a 15-year scheme to defraud tax authorities by failing to report and pay taxes on compensation for top executives. The Trump Organization could face a maximum of $1.61 million in fines when sentenced in mid-January. The guilty verdict comes as Trump is under scrutiny by federal and state prosecutors for his handling of classified documents, the effort to overturn the 2020 election results, and the accuracy of the Trump Organization's business records and financial statements. He is also facing a $250 million civil lawsuit from the New York attorney general alleging he and his adult children were involved in a decade-long fraud. The attorney general seeks to permanently bar them from serving as an officer or director of a company in New York state, among other penalties. Trump Org. attorneys said they plan to appeal.

Scientists identified a bacteria which uses a never seen trick to avoid antibiotics

Researchers have just caught bacteria sidestepping antibiotic treatment with a never-before-seen trick. Bacteria's talent for developing resistance against antibiotics is a rapidly growing health threat. This ability has ancient origins and allows drug-resistant bacterial infections like gonorrhoea to kill 1.3 million people globally yearly. Examples of strategies exploited by bacteria are: direct inactivation of the antibiotics, preventing drugs from accumulating in their system, and changing the antibiotic's targets, making them ineffective. Bacteria need their folates - a vitamin complex necessary for protein and DNA production - to develop and reproduce successfully. Some antibiotics block folate production to stop bacteria from growing and treat the infection. While investigating how a type of Streptococcus responds to antibiotics, Telethon Kids Institute microbiologist Kalindu Rodrigo and colleagues discovered a new mechanism for antibiotic evasion. Streptococcus commonly causes sore throats and skin infections but can also lead to systemic illnesses like scarlet fever and toxic shock syndrome. Scientists found a mechanism of resistance where, for the first time, the bacteria could take folates directly from its human host when blocked from producing their own. Streptococcus was acquiring folate, already processed, from outside its cells as these molecules are abundant in our bodies. The process completely bypasses the action of sulfamethoxazole, an antibiotic that inhibits folate synthesis within the bacteria, thus rendering the drug ineffective. The discovery's extent may impact preclinical research for antibiotics treatments. Indeed, bacteria that succumb to antibiotics in laboratory tests, where alternative folate sources are unavailable, may still thrive in their hosts' bodies. This study implies that most methods today may be inadequate for detecting resistance to some antibiotics.

The FDA approves the first faecal microbiota drug for the treatment of C. difficile infection

Infection by the bacterium C. difficile (CDI) is a severe and potentially deadly disease that impacts people across the globe. CDI causes debilitating symptoms such as severe diarrhoea, fever, stomach tenderness or pain, loss of appetite, nausea and colon inflammation. The U.S. Centers for Disease Control and Prevention declared CDI a public health threat requiring urgent and immediate action. The infections cause an estimated half a million illnesses and tens of thousands of deaths annually in the U.S. alone. It is often the start of a vicious recurrence cycle, implying a significant burden for patients and the healthcare system. It has been estimated that up to 35% of CDI cases recur after initial diagnosis, and people who have had a recurrence are at significantly higher risk of further infections. After the first recurrence, it has been estimated that up to 65% of patients may develop a subsequent recurrence. On November 30, the Food and Drug Administration (FDA) approved "Rebyota", commercialized by Ferring pharmaceuticals. What makes this drug exceptional and a first of its kind is its manufacturing and delivery method. The drug is manufactured in Minnesota from stool donations screened for dozens of infections and viruses. Health professionals deliver the therapy via the rectum as a one-time procedure. The studies worth the FDA approval demonstrated that 70% of patients taking Rebyota saw their symptoms resolve after eight weeks, compared with 58% of patients getting a placebo. The new treatment is only for patients who have already taken a course of antibiotics for recurrent infections. The condition is more common in seniors and people with weakened immune systems.

A global analysis demonstrates that nearly half stillbirths are caused by air pollution

A stillbirth occurs every 16 seconds somewhere in the world. It means that every year, about 2 million babies are stillborn – a loss that reaches far beyond the loss of life. It has a long-lasting traumatic impact on women and their families worldwide. Perhaps even more tragically, most of these deaths could have been avoided with high-quality care antenatally and during birth. Over 40 per cent of all stillbirths occurred during labour – a loss that could be prevented with improved monitoring and access to emergency obstetric care when required. This tragic loss of life remains a neglected issue, as worldwide data on stillbirths are mainly absent. A Neglected Tragedy: The Global Burden of Stillbirths, the first-ever stillbirth report by the UN Inter-Agency Group for Child Mortality Estimation (see link below), is a critical milestone in improving the availability of these data globally and driving political and public recognition of the issue. The report finds that despite progress being made since 2000, stillbirths have not declined as rapidly as maternal and newborn mortality. If current trends continue, an additional 19 million stillbirths will occur before 2030. A first global study, published November 29 in Nature Communications, may explain this negative trend as it reveals a link between stillbirths and air pollution. The research used data on stillbirths and air pollution between 1998 and 2016 from 54 low- and middle-income countries, including Pakistan, India and Nigeria. The researchers estimated the number of stillbirths attributable to PM2.5 exposure. PM2.5 are microscopic particles usually found in smoke, having a diameter of 2.5 micrometres (0.0025 mm) or smaller. The study concludes that in 2015 there were 830'000 stillbirths attributable to exposure to pollution (40% of the total). The proportion of stillbirths attributed to PM2.5 pollution was exceptionally high in Pakistan, India, Nigeria and China. The underlying biological mechanisms are not yet clear. The researchers hypothesize that pollution particles passing through the placenta could cause "irreversible embryonic damage" and harm the placenta itself. Air pollution could also restrict the ability of the mother's body to pass oxygen to the foetus. Overall, independently of the exact causes, the study shows that reducing air pollution levels would reduce the risks of stillbirth.

Artificial Intelligence is now drawing pictures on request, and they can be as beautiful as human-made ones

Progress in the domain of Artificial Intelligence (AI) is expected to change the world in a few decades. Such continued progress has been recently demonstrated by applying AI programs to games such as Chess and Go, where computers proved to be able to learn and win against the top human champions. Recently another AI program, DALL-E, demonstrated unprecedented power in creating original images. The program is now available online (see link below), and anyone can use it: it asks the user to enter the content of the desired image and, in a matter of seconds, creates images reflecting the user's requests. DALL-E is one of the most discussed, appreciated and criticized artificial intelligence algorithms, especially since the end of the summer when a trial version of it was made available to everyone. The first version of this artificial intelligence was released in January 2021, but with limited capabilities compared to the current ones, which surprised many observers and instilled concern in illustrators, graphic designers and artists. OpenAI carried out the development of DALL-E. This research laboratory is part of the OpenAI LP company, which is, in turn, controlled by Open AI Inc., a non-profit corporation. Billionaire Elon Musk founded the organization in 2015. For some months now, DALL-E has been the best-known system for producing images with algorithms, but there are others. Several other research groups, developers, companies, and organizations have made AI drawings, such as Midjourney, Imagen and DreamStudio. Each of these systems employs different algorithms but with similar operating principles. The original breakthrough came in 2016 when a team of scientists managed for the first time to ask an AI algorithm for the content of an image through a written request. The initially designed algorithms, however, were quite complex to use and specialized only in a small niche of demands. The most recent developments result in systems such as DALL-E that can practically design anything, with ever higher levels of adherence to requests. The latest generation of these AIs is straightforward to use. Just as researchers in Canada had experienced in 2016, but with much larger and more defined images, it is now possible to write a request in natural language and obtain the corresponding drawing in a few moments. Many aspects of DALL-E functioning are unknown, but its programmers have reported adding elements to ensure that the images produced respond to a specific aesthetic taste. As far as possible, the AI ​​produces images that we should like and, consequently, that we believe are more in line with our requests, amplifying that impression of having what we asked for. For example, asking for a specific desired painting style is possible. Those who deal with graphics and illustrations have begun to show a particular concern, sometimes intolerance, towards the AIs that draw and manage to draw better and better. One day, perhaps not too far away, for some types of illustrations, the work of professionals could be replaced by AI. Even if this did not happen in other sectors, such as writing - where there is massive room for improvement - the advances in drawing with AI have been faster and are, above all, more promising.
