Pakistani Researchers at CERN Lab in Switzerland
One of the most important discoveries in Physics since Einstein's Theory of Relativity has possibly just been made at CERN and dozens of Pakistani scientists have contributed to it.
Scientists at CERN claim that they have discovered the Higgs field, also nicknamed the "God particle" that travels faster than light, thereby proving Einstein wrong, according to the Associated Press reports.
"The feeling that most people have is this can't be right, this can't be real," the AP story quotes James Gillies, a spokesman for the European Organization for Nuclear Research.
The most high-profile effort to find "God Particle" is taking place about 300 ft below ground in a tunnel at the French-Swiss border. Buried there is a massive particle accelerator and super collider called LHC (Large Hadron Collider) run by the Swiss lab CERN (European Organization of Nuclear Research), which has two beams of particles racing at nearly the speed of light in opposite directions and the resulting particles produced from collisions are being detected by massive detectors in the hope of experimentally finding the fundamental particle of which everything in the universe is built from: God Particle.
Among the world scientists working at CERN on LHC project is Professor Hafeez Hoorani of Pakistan's Quaid-e-Azam University in Islamabad. He is one of 27 Pakistani scientists at CERN.CERN is the most highly respected research lab in Switzerland responsible for LHC. He acknowledges that Pakistan government's support for Pakistani scientists' serious involvement at CERN materialized only after 1999, the year former President Musharraf's government assumed power. He also gives credit to Dr. Abdus Salam, Pakistan's only Nobel Laureate, for inspiring him and his colleagues to pursue serious scientific research. Here's what Professor Hoorani says about Pakistan's involvement in LHC and CERN:
When I first came to CERN, I was mainly working on technical things but became increasingly involved in political issues. In 1999, I went back to Pakistan to set up a group working on different aspects of the LHC project. There I had to convince my people and my government to collaborate with CERN, which was rather difficult, since nobody associated science with Switzerland. It is known as a place for tourism, for its watches, and nice places to visit.
However, Pakistan already had an early connection to CERN through the late Abdus Salam, the sole Nobel laureate from Pakistan in science and one of the fathers of the electroweak theory. CERN has been known to the scientific community of Pakistan since 1973 through the discovery of neutral currents which eventually led to the Nobel Prize for Salam. We are contributing much more now because of the students who worked with Salam, who know his theories and CERN, and who are now placed at highly influential positions within the government of Pakistan. They have helped and pushed Pakistan towards a very meaningful scientific collaboration with CERN. People now know that there is an organization called CERN. It took a long time to explain what CERN is about, and I brought many people here to show them, because they did not imagine CERN this way. Many people support us now which gives us hope…”
In addition to the 27 scientists, Pakistan has made material contributions to the tune of $10m. Pakistan signed an agreement with CERN which doubled the Pakistani contribution from one to two million Swiss francs. And with this new agreement Pakistan started construction of the resistive plate chambers required for the CMS muon system. While more recently, a protocol has been signed enhancing Pakistan’s total contribution to the LHC program to $10 million.
CERN is a pan-European effort and all of its member states are European. Pakistan, with all of its contributions to LHC project, is hoping to join the ranks of India, Israel, Japan, Russia, Turkey and United States as an observer state at CERN.
Pakistan has contributed the LHC in numerous ways including some of the following in particular:
1. Detector construction
2. Detector simulation
3. Physics analysis
4. Grid computing
5. Computational software development
6. Manufacturing of mechanical equipment
7. Alignment of the CMS (Compact Muon Solenoid) tracker using lasers
8. Testing of electronic equipment
9. Barrel Yoke: 35 Ton each feet made in Pakistan
10. Assembly of CF (Carbon Fiber) Fins for the Silicon Tracker’s TOB (Tracker Outer Barrel).
11. 245 of the 300 CMS chambers required were made in Islamabad.
The Higgs boson, also known as "God Particle", is a hypothetical massive scalar elementary particle predicted to exist by the Standard Model of particle physics. It is the only Standard Model particle not yet experimentally observed. An experimental observation of it would help to explain how otherwise massless elementary particles cause matter to have mass. More specifically, the Higgs boson would explain the difference between the massless photon and the relatively massive W and Z bosons. Elementary particle masses, and the differences between electromagnetism (caused by the photon) and the weak force (caused by the W and Z bosons), are critical to many aspects of the structure of microscopic (and hence macroscopic) matter; thus, if it exists, the Higgs boson is an integral and pervasive component of the material world.
The Standard Model of particle physics has its limits. It can't explain several big mysteries about the universe that have their roots in the minuscule world of particles and forces. If there's one truly extraordinary concept to emerge from the past century of inquiry, it's that the cosmos we see was once smaller than an atom. This is why particle physicists talk about cosmology and cosmologists talk about particle physics: Our existence, our entire universe, emerged from things that happened at the smallest imaginable scale. The big bang theory tells us that the known universe once had no dimensions at all—no up or down, no left or right, no passage of time, and laws of physics beyond our vision.
There have been many other efforts to build particle accelerators and supercolliders including SLAC (Stanford Linear Accelerator) and Fermi Collider, but none so ambitious and massive as the LHC. This discovery, if indeed confirmed, will advance human knowledge dramatically and eventually help treat diseases, improve the Internet, and open doors to travel through extra dimensions, according to the scientists associated with it.

Despite the problems, science has been flourishing in Karachi and other Pakistani cities, thanks to an unprecedented investment in the country's higher-education system between 2002 and 2008 (see 'Rollercoaster budget'). As funding increased more than fivefold in that time, new institutes focusing on proteomics and agricultural research sprouted, and the University of Karachi's natural sciences department rose from nowhere to 223 in the 2009 QS World University Rankings.
-----------
The surge in higher-education investment occurred after the rise to power of General Pervez Musharraf in 1999, who as leader of the army had led a low-key coup d'état and installed himself as de facto president. Musharraf was a liberal progressive who hoped to modernize Pakistan. "It was a moment in Pakistani history that now seems so distant," says Adil Najam, an expert in international development at Boston University in Massachusetts.
With the economy booming in the early 2000s, Pakistani academics sensed an opportunity. Higher education had never had much popular support in the country, where literacy hovers at about 50%, but in Musharraf they saw a champion. In a series of reports, Najam and others made the case that if the nation could mobilize its universities, it could transform from a poor agricultural state into a knowledge economy (see Nature 461, 38–39; 2009). The group called for a new Higher Education Commission (HEC) to manage the investment, as well as better wages for professors, more grants for PhD students and a boost in research funding.
-------------
Rahman, a chemist at the University of Karachi and, at the time, the minister for science and technology, enthusiastically set out to overhaul the nation's universities. With Musharraf's support, annual research funding shot up 474% to 270 million rupees (US$4.5 million in 2002) in the first year alone. The HEC set aside money for PhD students and created a tenure-track system that would give qualified professors a monthly salary of around US$1,000–4,000 — excellent pay by Pakistani standards.
Rahman's strong scientific background, enthusiasm for reform and impressive ability to secure cash made him a hit at home and abroad. "It really was an anomaly that we had a person of that stature with that kind of backing," says Naveed Naqvi, a senior education economist at the World Bank, based in Islamabad. "Atta-ur-Rahman was a force of nature."
--------
Between 2003 and 2009, Pakistan churned out about 3,000 PhDs, roughly the same number awarded throughout its previous 55-year history. More than 7,000 PhD students are now in training at home and abroad. Meanwhile, scientific research publications have soared from roughly 800 in 2002 to more than 4,000 in 2009 (see 'Publishing power')...

....Of these five centers, one is the only institute for human clinical trials in Pakistan, the other a core of computational biology and the third provides consultancy to people suffering from genetic diseases.
----
The centers and their growth have been working towards what has been termed as a ‘silent revolution’ and had been described by Professor Wolfgang Voelter of Tubingen University as a ‘miracle.’
The Hussain Ebrahim Jamal (HEJ) Research Institute of Chemistry was only a small post graduate institute before a generous donation of Rs 5 million in 1976 set the center towards the path of excellence. Latif Ebrahim Jamal’s endowment, on behalf of the Hussain Ebrahim Jamal Foundation, was the largest private funding for science in Pakistan at the time.
The center houses old NMR machines of 300 megahertz to state-of-the-art Liquid Chromatograph Nuclear Magnetic Resonance (LCNMR).
Under the leadership of eminent chemist Dr Salimuzzaman Siddiqui and Dr Atta-ur-Rehman, the institute became a magnet for more funding and projects from around the world. Over a period of time, it received $30 million in funding from various countries. Recently, Islamic Development Bank (IDB) donated $ 40 million for research on regional and tropical diseases. Dr Atta-ur-Rehman, a renowned chemist and the former chairman of Higher Education Commission said,

Currently, the center has one of the largest PhD programs in the country in the fields of natural product chemistry, plant biotechnology, computational biology, spectroscopy and other disciplines at the frontiers of science.

The ground floor of the institute holds 12 state-of-the-art Nuclear Magnetic Resonance (NMR) machines that are vital in the research of the structure, reaction and other properties of various compounds and molecules, as well as an X-ray crystallography setup which uses X-rays to learn the structure of crystalline material.
The X-ray crystallography setup is used to construct 3-D structures of molecules under study. -Photo by author

“We have recently finished the structure of a compound showing anti-inflammatory activity,” said Sammer Yousuf, senior research officer at the institute who was awarded the Regional Prize for Young Scientists by the Third World Academy of Sciences (TWAS) in 2011 for her work.
“In the last two and a half years our institute was awarded 24 international patents,” Dr Rehman proudly adds.
Since its inception, the HEJ which was inducted into the International Center for Chemical and Biological Sciences (ICCBS) in the ‘90s has produced hundreds of doctorates, thousands of papers and hundreds of international patents, and also helps over 350 industries across Pakistan. The Industrial Analytical Center at the HEJ provides testing, consultancy and research for various industries in Pakistan.
The construction of a state-of-the-art center for nanotechnology is underway while the Jamil-ur-Rehman Center for Genome Research, also falling under HEJ, is almost complete. The center, named after Dr Rehman’s father who was the main donor of the institute, already houses modern gene sequencing machines.

https://phys.org/news/2023-01-migration-academics-economic-necessarily-brain.html
A team of researchers at the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, developed a database on international migration of academics in order to assess emigration patterns and trends for this key group of innovators. Their paper was published in PNAS on Jan. 18.
As a first step, the team produced a database that contains the number of academics who publish papers regularly, and migration flows and migration rates for all countries that include academics who published papers listed on the bibliographic database Scopus. The migration database was obtained by leveraging metadata of more than 36 million journal articles and reviews published from 1996 to 2021.
"This migration database is a major resource to advance our understanding of the migration of academics," says MPIDR Researcher Ebru Sanliturk. Data Scientist Maciej Danko adds: "While the underlying data are proprietary, our approach generates anonymized aggregate-level datasets that can be shared for noncommercial purposes and that we are making publicly available for scientific research."
MPIDR Researcher Aliakbar Akbaritabar explains how they processed the bibliographic data in order to receive information about the migration patterns of academics: "We used the metadata of the article title, name of the authors and affiliations of almost every article and review published in Scopus since 1996. We followed every single one of the roughly 17 million researchers listed in the bibliographic database through the years and noticed changes in affiliation and, by using that tactic we know how many academics left a given country every year."
The researchers' empirical analysis focused on the relationship between emigration and economic development, indicating that academic setting patterns may differ widely from population-level ones.
Previous literature has shown that, as low-income countries become richer, overall emigration rates initially rise. At a certain point the increase slows down and the trend reverses, with emigration rates declining.
This means that favoring economic development has the counterintuitive effect of initially increasing migration from low- and middle-income countries, rather than decreasing it.
Is this pattern also generally valid for migration of scientists?
Not really.
The researchers found that, when considering academics, the pattern is the opposite: in low- and middle-income countries, emigration rates decrease as the gross domestic product (GDP) per capita increases. Then, starting from around 25,000 US Dollars in GDP, the trend reverses and emigration propensity increases as countries get richer.
MPIDR Director Emilio Zagheni adds, "Academics are a crucial group of innovators whose work has relevant economic effects. We showed that their propensity to emigrate does not immediately increase with economic development—indeed it decreases until a high-income turning point and then increases. This implies that increasing economic development does not necessarily lead to an academic brain drain in low- and middle-income countries."
Unveiling these and related patterns, and addressing big scientific questions with societal implications, was possible only because of painstaking work in preparing this new global database of migration of academics. "We are putting the final touches on an even more comprehensive database, the Scholarly Migration Database, which will be released on its own website soon," says software developer Tom Theile.

Geneva and Hamburg, 28 June 2023. In 2023, for the second time in the history of the Beamline for Schools competition, the evaluation committee selected three winning teams. The team “Myriad Magnets” from the Philips Exeter Academy, in Exeter, United States, and the team “Particular Perspective”, which brings together pupils from the Islamabad College for Boys, the Supernova School in Islamabad, the Cadet College in Hasanabdal, the Siddeeq Public School in Rawalpindi and the Cedar College in Karachi, Pakistan, will travel to CERN, Geneva, in September 2023 to perform the experiments that they proposed. The team “Wire Wizards” from the Augustinianum school in Eindhoven, Netherlands, will be hosted at DESY (Deutsches Elektronen-Synchrotron in Hamburg, Germany) to carry out its experiment.
Beamline for Schools (BL4S) is a physics competition open to secondary school pupils from all around the world. The participants are invited to prepare a proposal for a physics experiment that can be undertaken at the beamline of a particle accelerator. A beamline is a facility that provides high-energy fluxes of subatomic particles that can be used to conduct experiments in different fields, including fundamental physics, material science and medicine.
---
“Congratulations to this year’s winners – may they have good beams, collect interesting data and generally have the time of their lives,” says Christoph Rembser, a CERN physicist at the ATLAS experiment and one of the founders of Beamline for Schools. “Every year I am astonished by how many young people submit very creative, interesting proposals. In 2014, we weren’t sure at all whether this competition would work. Ten years and 16 000 participants later, I am proud to say that it is obviously a resounding success.”
The fruitful collaboration between CERN and DESY started in 2019 during the shutdown period of the CERN accelerators. This year, the German laboratory will host its fifth team of winners.
------
The Pakistan team “Particular Perspective” will measure in detail the beam composition of the T10 beamline of the CERN Proton Synchrotron accelerator. The experiment set-up they designed will make it possible to differentiate between different particle species and measure their intensity.
“I am grateful to BL4S for having provided me with an opportunity to represent my country, Pakistan, and its budding community of aspiring physicists. This is a chance for us to experience physics at the highest level and will inspire people with interests similar to ours to reach greater heights,” says Muhammad Salman Tarar from the “Particular Perspective” team.
-------
The “Wire Wizards” team’s experiment focuses on detector development. The Dutch students designed and built a multi-wire proportional chamber (MWPC), a gas detector able to measure the position of a particle interacting with it, and they plan to characterise it using the electron beam available at DESY.
“The BL4S competition provides us with a unique educational experience that will be a highlight in our time as students,” says Leon Verreijt from the “Wire Wizards” team.
The winners have been selected by a committee of CERN and DESY scientists from a shortlist of 27 particularly promising experiments. All the teams in the shortlist will be awarded special prizes. In addition, one team will be recognised for the most creative video and 10 teams for the quality of physics outreach activities they are organising in their local communities, taking advantage of the knowledge gained by taking part in BL4S.
