It was October 11, 1939, and Alexander Sachs knew that it was his turn to enter the President’s office. He was allotted a brief amount of time to meet the President. But what Sachs had in mind to say was no ordinary matter – the World War had begun, with the German invasion of Poland just over a month ago. Franklin D Roosevelt was on an absolutely busy schedule. But this was the only time Sachs was going to get – to alert and advise the President of the United States of a possible nuclear attack from Germany.

As Einstein put it, “I know not what weapons World War III will be fought, but World War IV will be fought with sticks and stones.” 

Just over a month ago Sachs was contacted by Leo Szilard, an American-Hungarian physicist.  He discussed the potential application of the element uranium, to sustain a nuclear chain reaction, creating vast amounts of energy that could even level whole cities.

Szilard discussed with Albert Einstein the potential use of such nuclear weapons by Germany. Einstein signed a letter drafted by Szilard and requested Sachs to read it out to the President, primarily because of Sachs’ closeness to President Roosevelt and the fact that he would get clearance immediately. Sachs agreed to deliver the message and added his summary of the consequences of nuclear technology.

In the limited time he conversed with Roosevelt, Sachs was unsure whether he struck a chord with the President over the potential use of nuclear energy as a weapon of mass destruction. Additionally, Sachs mentioned the German move to bar the sales of uranium ore from neighboring Czechoslovakia, and linked it to a possible sign of development in their nuclear ambition.

Nevertheless, Roosevelt invited Sachs again for breakfast the next day at the White House. Sachs paced about his hotel room that night, and even strolled out to meditate, as he planned how to present his argument.

Later that morning over breakfast, Sachs, in his moment of inspiration, remembered Napoleon’s rejection of an offer from Robert Fulton during the Napoleonic Wars (1800-1815) to create steamships that could invade England directly. However, Napoleon thought ships without sails could never be created. This shortsightedness led the British to invent and use steamships to defeat the French in the end of the war.

Roosevelt realized the potential threat the German possession of these nuclear weapons would pose, and was famous to have told his aide, General Edwin “Pa” Watson, immediately “Pa, this needs action!”

Roosevelt had set up the Uranium Committee to research the potential application of uranium to build nuclear weapons. However, the Committee barely scratched the surface for over 2 years, since the US was not at war yet. It was only in December 1941, that the US put effort into the nuclear weapons program. However, concluding that it would take a huge load of a thousand tons to detonate these devices slowed down progress. But the breakthrough arrived, when their British allies, as part of their own MAUD Committee (similarly researching the feasibility of nuclear weapons) discovered the “critical mass” of uranium-235 (the isotope used in nuclear fission chain reactions) is barely 10 kg.

It was an important revelation and the subsequent Quebec Agreement, between the British and the US governments (signed by Winston Churchill and Frank Roosevelt), sealed their special relationship in transferring and cooperating nuclear energies and technologies. And hence the British nuclear program (a.k.a. Tube Alloys), was merged with the US nuclear program (a.k.a. Manhattan Project).

The project progressed over the next 27 months, culminating at the deserts of Jornada del Muerdo, in the state of New Mexico – with the detonation of the first nuclear device – the “Gadget” as part of Trinity (code name for the test). Robert Oppenheimer, who led the nuclear program remarked at the end of the Trinity test, “Now I am become death, the destroyer of worlds,” a quotation from the Bhagavad Gita.

It later dawned on the US in 1945, that the Germans did not possess a nuclear weapon, or did not try to build one – although they had a division researching uranium during the war. With imminent German defeat, the use of a nuclear weapon against them was now unjustified. However, the Japanese became the natural target as they were the only functioning adversary.

It dawned to Leo Szilard that the US may consider using the bomb, especially after the unsuccessful conclusion to the Postdam Conference, where they discussed a policy to coerce the Japanese into surrendering unconditionally.

Before Szilard’s new letter arrived at the White House, asking then President Harry Truman to reconsider the use of nuclear weapons in war, Hiroshima and Nagasaki were both destroyed in nuclear strikes, forcing the Japanese to surrender a week later, thus ending the World War.

The use of the bomb has rather been controversial. On one side, people doubted the indiscretion displayed by Truman, calling the killings of thousands of civilians as a war crime. However, Truman said he was convinced that if he did not order the attack, the Japanese would have never surrendered and prolonged the war, adding more death, destruction and misery.

The creation of the atomic bomb heightened the consequences of war. After the Soviet Union, the United Kingdom, France, China, India, Pakistan and North Korea created their own nuclear weapons – some of them thousands of times more powerful than the bomb detonated over Hiroshima and Nagasaki, the world has realized largely that another World War would end in mutual destruction.

As Einstein put it, “I know not what weapons World War III will be fought, but World War IV will be fought with sticks and stones.”

Will Canada remain a hub for Indian students amidst new restrictions?

New restrictions on student visas and work permits have sparked debate about the future of Canada as a preferred educational hub

As Canada continues to position itself as a leading destination for international students, recent policy changes are raising concerns about its appeal, particularly among Indian students. New restrictions on student visas and work permits have sparked debate about the future of Canada as a preferred educational hub.

In the past decade, Canada has seen a surge in international students, with Indian nationals being a significant contributor to this growth. According to recent statistics, Indian students constitute one of the largest groups of international students in Canada. India sent 225,000 students to Canada, a number that rose to 278,000 in 2023. For the first half of 2024, the count has reached 100,000 students. However, new regulations imposed by Canadian authorities aim to address issues of overstaying and unauthorized work, potentially impacting this vibrant demographic.

Policy Changes and Immediate Implications

The Canadian government’s recent policy changes include stricter requirements for student visas and modifications to work permit conditions. Under the new regulations, international students will face more rigorous checks before their applications are approved. Additionally, there are enhanced restrictions on the type and amount of work international students can undertake while studying.

The new rules mandate that students must now provide more detailed evidence of financial stability and academic intentions. Moreover, there will be an increase in the frequency of status reviews and a more stringent enforcement of existing work permit regulations. These measures are designed to curb the misuse of student visas and ensure that students adhere to their intended study programs.

For many Indian students, these changes represent a significant shift in their academic and professional plans. “The new restrictions have created a wave of uncertainty among students planning to study in Canada,” says Arjun Patel, a recent high school graduate who was preparing to enroll in a Canadian university. “We’re concerned about how these policies will affect our ability to work part-time and support ourselves while studying.”

Impact on Current and Prospective Students

For current international students in Canada, the immediate impact of these policy changes includes increased stress over visa renewals and job security. Many students who rely on part-time work to support their education and living expenses might find themselves restricted by the new regulations. This could lead to financial strain and affect their academic performance.

Jose Jacob, a Canadian immigrant, attributes the recent restrictions on international students in Canada to a combination of political and economic factors. “Education is a billion-dollar industry for Canada,” Jacob notes. “When I arrived here, and for many years since, community colleges have been major promoters of study abroad programs. Many of these institutions are private community colleges operating like businesses. More foreign students mean higher fees, which significantly boosts the industry.”

Jacob also points out that the Trudeau government has traditionally been supportive of immigration. Under Prime Minister Justin Trudeau, Canada has welcomed international students, offered residency, and invited refugees. “Trudeau’s policies are driven by the immigrant vote bank,” Jacob explains.

Prospective students face the challenge of navigating a more complex visa application process. The enhanced scrutiny may lead to longer processing times and additional paperwork, potentially causing delays in starting their studies. “The increased documentation requirements and the possibility of visa rejections have made the application process more daunting,” notes Rina Sharma, a prospective student from Delhi. “We’re concerned about how these changes will affect our plans and whether it will be worth the investment.”

Canada’s Commitment to International Education

Despite the new restrictions, Canadian officials have reiterated their commitment to international education. They emphasize that the changes are intended to preserve the integrity of the student visa system and ensure that students are genuinely pursuing their educational goals. The recent decision to impose restrictions on foreign students came amid significant domestic protests. “The decision was announced during a period of considerable political pressure,” Jose Jacob adds. He also highlights that the rising cost of living and housing shortages in places such as Ontario have contributed to the government’s decision. “The surge in housing prices and the increase in the cost of goods led to saturation,” he says.

“Canada remains dedicated to attracting top talent from around the world,” says, a spokesperson of a global education consulting group. “These policy adjustments are necessary to prevent abuse of the system and to ensure that our programs continue to benefit students who are committed to their studies.”

Moreover, educational institutions in Canada are working to support international students through these transitions. Many universities are enhancing their advisory services to help students navigate the new regulations and adjust their plans accordingly.

The Future of Canada as an Educational Destination

As Canada navigates these new policy changes, it faces the challenge of maintaining its status as a leading destination for international students. While the regulations are designed to address specific issues, they must balance the need for oversight with the desire to remain an attractive option for students worldwide.

For Indian students, the changing landscape presents both challenges and opportunities. While the new restrictions may complicate the immediate future, Canada’s robust educational infrastructure and diverse academic offerings continue to make it a compelling choice for many. The key will be how well the country can adapt to these changes while continuing to offer a supportive and enriching environment for international learners.

Jacob suggests that these new regulations are also aimed at curbing fraudulent courses. “Previously, the U.S. was marketed to Europeans as the ‘Land of Opportunities,’ attracting early settlers. Similarly, Canada has been marketed as a land of opportunity for Indian students. Community colleges have collaborated with local educational consulting agencies to promote this image. However, the situation has become too saturated. Technical jobs are in higher demand now, and Canada remains a good option for students in those fields.”

Jacob also warns prospective students about the financial realities of living in Canada. “For those coming here to make money, it’s important to understand that it’s not like the Gulf countries. Taxes are very high—13 percent on everything,” he advises. “It’s crucial to be aware of these factors before making the move.”

To sum up, as Canada adjusts its policies regarding international students, it will be crucial for both the government and educational institutions to address the concerns of students and ensure that the country remains a welcoming and viable destination for those seeking higher education. The coming months will reveal whether Canada can sustain its reputation as a global education hub amidst these evolving regulations.

In a groundbreaking study, researchers at the Institute of Advanced Study in Science and Technology (IASST) in Guwahati, India, have discovered that Selegiline, an antidepressant drug, may offer a cost-effective alternative for breast cancer treatment. The research, led by Dr. Asis Bala, reveals that Selegiline, a monoamine oxidase (MAO) inhibitor, could be repurposed as an anticancer therapeutic.

The team’s findings, published in the journal Medical Oncology, demonstrate that Selegiline interacts with ten genes associated with various cancers. Their preliminary tests on six different cancer cell lines showed Selegiline’s efficacy in targeting both estrogen and progesterone-positive (ER+ & PR+) and triple-negative breast cancer (TNBC) cells. This research group has shown that Selegiline (L-deprenyl), an antidepressant drug from a class of drugs called monoamine oxidase (MAO) inhibitors, might be applied as anticancer therapeutics for breast cancer.

Unlike conventional therapies that rely on reactive oxygen species (ROS) to induce cell death, Selegiline operates through a different mechanism. It has been shown to inhibit protein kinase C phosphorylation, a process believed to be involved in its cancer-fighting effects.

Selegiline showed integrated networking with genes and diseases of different cancers. It also showed the inhibitory effect of PKC phosphorylation and ROS-independent apoptosis in breast cancer cells.

This novel application of Selegiline marks a significant step forward in cancer research. The study’s results highlight the need for further investigation into the drug’s in vivo efficacy, optimal dosing, and potential side effects. This approach could pave the way for more accessible and affordable breast cancer treatments in the future.
