Pakistan to send first astronaut to space in 2026; project is handled by..., what is SUPARCO and who was Nobel Prize-winning Abdus Salam?
(Representational image: New Delhi: Just a few weeks back, Group Captain and Test Pilot Shubhanshu Shukla of the Indian Air Force (IAF) became the second Indian to go to space. The first Indian to travel to space was Rakesh Sharma, also from the IAF, who made India proud in April 1984. Shubhanshu Shukla was the mission pilot for Axiom Mission 4 and the first ISRO astronaut to visit the International Space Station (ISS). Now, it seems like the 'not so friendly' neighbourhood Pakistan wants to emulate the feat, as the news of the country's preparation to blast off one of its citizens to the Chinese space station in 2026. No prizes for guessing that! What is Pakistan's space programme, and what is SUPARCO? Going back to India, it has its space agency, the Indian Space Research Organisation (ISRO), which was set up in 1962 by the Government of India, and since then, it has achieved numerous milestones. As for Pakistan, its space agency SUPARCO (Space and Upper Atmosphere Research Commission), was started in 1961, which means even before India. The China National Space Administration (CNSA), the space agency of China, was established in 1993. Given the fact that Pakistan has lagged by a very long distance. Pakistan's SUPARCO launched its first rocket, 'Rahbar-1', in 1962, which was a big achievement at that time. In 1990, it launched its first satellite, 'Badar-1', with the help of China. That was the last significant programme undertaken by Islamabad. A big credit for the establishment and success of SUPARCO goes to Nobel Prize-winning scientist Abdus Salam. Who was Abdus Salam? Mohammad Abdus Salam was a Pakistani theoretical physicist who was awarded the 1979 Nobel Prize in Physics for his contribution to the electroweak unification theory. He was the first Pakistani and the first scientist from an Islamic country to receive a Nobel Prize. Salam was the scientific advisor to the Ministry of Science and Technology in Pakistan from 1960 to 1974. He played a major and influential role in the development of the country's science infrastructure. Salam contributed to numerous developments in theoretical and particle physics in Pakistan. Abdus Salam was the founding director of the Space and Upper Atmosphere Research Commission (SUPARCO) and was responsible for the establishment of the Theoretical Physics Group (TPG). He is viewed as the 'scientific father' of this program. What kind of problems is SUPARCO facing? For any programme of such a big magnitude, it is a given that it will require loads of funding, which SUPARCO did not receive from the Pakistani government. This hurt the space agency as well as its space programme. How serious it is about Space Science can be gauged from the fact that the annual budget of SUPARCO is only $36 million, which is peanuts. What is even more surprising is that for the last 11 years, retired army officers and generals have been running the agency, which should have been under the patronage of space scientists and professionals from related fields. There are fewer space-related courses in education, due to which skilled people are not being prepared. Space research in Pakistan suffered due to the focus on the nuclear programme and dependence on China. Pakistan launched three satellites in recent years, but all with Chinese help. The same is the story with the first Pakistani astronaut in 2026, who is also scheduled to be dependent on China's space station. Two Pakistani astronauts will undergo trained in China.

What scientists just found between coffee and antibiotics may surprise you
New research indicates caffeine might affect bacteria in our bodies. A German study suggests caffeine reduces a protein that helps antibiotics enter E. coli. This could make antibiotics less effective. However, scientists clarify this doesn't mean coffee stops antibiotics from working. More research is necessary to confirm these lab findings in humans. New lab study reveals caffeine may reduce antibiotic sensitivity in E. coli but experts say your morning coffee is still safe Tired of too many ads? Remove Ads The relation between protein and caffeine Tired of too many ads? Remove Ads Drinking coffee is part of daily life for millions of people, but new research shows it might have an unexpected effect on the bacteria living in our bodies.A laboratory study by scientists in Germany suggests that caffeine may make E. coli bacteria less sensitive to some antibiotics. E. coli is a common type of bacteria that usually lives harmlessly in the gut but can cause infections such as food poisoning or urinary tract infections The study, published July 22 in the journal PLOS Biology, looked at how E. coli responded to 94 different chemicals, including medicines like aspirin, natural compounds in the body, and ingredients in food like vanilla and the researchers found was surprising, caffeine reduced the levels of a protein called OmpF, which helps certain antibiotics, like ciprofloxacin and amoxicillin, enter the bacterial cell. If there's less OmpF, the antibiotics can't get inside the bacteria as easily, which could make them less before you consider giving up your morning coffee, scientists want to make one thing very clear, this does not mean drinking coffee will stop antibiotics from working in your scientists even tested caffeine's effect on a real E. coli sample taken from a patient with a urinary tract infection. The same thing happened, the bacteria made less of the OmpF protein . Still, this was a lab study, not a real-world clinical trial. That means we don't yet know if caffeine affects antibiotics the same way inside the human study also found that a gene regulator called Rob was involved in many of the changes. This protein helps bacteria turn other genes on or off, and it may be more important than researchers previously short, caffeine might change how bacteria react to antibiotics, but experts say more research is needed. For now, doctors say to keep drinking your coffee and follow your doctor's instructions if you're taking antibiotics.

New vistas for nurses with German skills: APSSDC MD
How large is the pool of unemployed nurses in AP? There are around 32,000 sanctioned seats for nursing courses in the State. Every year, nearly 26,000 graduates pass out, and a significant number remain unemployed due to limited local job opportunities. When was the German Language Training (GLT) initiative launched? The programme began in 2023. From the first batch, 15 candidates underwent training, and two nurses have cleared the B2 level exam. They are preparing to move to Germany for job. What awareness initiatives have been taken to promote overseas placements? We have signed (Memoranda of Understanding) MoUs with four training partners, conducted a workshop with principals from 32 nursing colleges, and held awareness drives in over 80 institutions. We also used flyers, social media, and the press to widen our outreach. What kind of response are you seeing from the nursing community? The response has been very positive. Colleges are actively looking for German tutors, and many graduates are increasingly interested in pursuing placements abroad, especially in Germany.
