Three American physicists Rainer Weiss, Barry Barish and Kip Thorne on Tuesday won the Nobel Prize in Physics for discovering the gravitational waves, ripples in the fabric of spacetime, a phenomenon anticipated by Albert Einstein a century ago.

Gravitational waves are extremely faint ripples in the fabric of space and time, generated by some of the most violent events in the universe.

The Royal Swedish Academy of Sciences in Stockholm announced that Rainer Weiss will be awarded one half of the 9m Swedish kronor (£825,000) prize, whereas  Kip Thorne and Barry Barish will share the other half of the prize.

The credit for discovering the gravitational waves will go to all three scientists who led the Laser Interferometer Gravitational-Wave Observatory, or Ligo, experiment, which enabled them to observe gravitational waves in September 2015.

Weiss, emeritus professor of physics at Massachusetts Institute of Technology is an experimentalist who made major contribution in the concept design, funding and the construction of the observatory.

Kip Thorne, who is the professor of theoretical physics at California Institute of Technology made crucial predictions of how to identify the gravitational wave and how it would look.

Barry Barish,  a former particle physicist at California Institute of Technology (now emeritus professor) is credited for getting the experiment off the ground. The scientist saw the project through – it was in danger of being cancelled when he took over as the second director of Ligo in 1994.

Ronald Drever, a Scottish physicist, who alongside Weiss and Thorne played a leading role in developing Ligo, died in March from dementia less than 18 months after gravitational waves were first detected. The Nobel prize is not normally awarded posthumously.

The Ligo is designed to detect a distortion of a thousandth of the diameter of an atomic nucleus across a 4 Km length of laser beam. The phenomenon detected was the collision of two black holes. With the most sophisticated detector, the scientists listened for 20 thousandths of a second as the two giant black holes, one 35 times the mass of the sun, the other slightly smaller, circled around each other. The two objects had begun by circling each other 30 times a second. By the end of the 20 millisecond snatch of data, the two had accelerated to 250 times a second before the final collision and a dark, violent merger.

Nobel Prize was first awarded in 1901 for achievements in science, literature and peace, in accordance to the will left by Swedish business tycoon Alfred Nobel who had bequeathed much of the fortune he generated from his discovery of dynamite.

Among the science prizes, physics has often taken centre stage with laureates including scientific superstars such as Einstein, Niels Bohr and Marie Curie, one of only two women to win a Nobel Prize for Physics.[/vc_column_text][/vc_column][/vc_row]

Trump says Iran getting more serious in talks, no decision yet on major strikes

Donald Trump says Iran is becoming more serious in negotiations with the US but insists no decision has been taken on launching major military strikes against Tehran.

US President Donald Trump has said he has not yet decided whether to authorise major military strikes against Iran, stating that Tehran has become “more serious” in its negotiations with Washington even as tensions between the two countries remain high.

Speaking to reporters in the Oval Office on Friday, Trump said discussions with Iran were continuing and suggested diplomatic efforts were showing signs of progress.

“We’re talking to them right now. I think they’re getting more and more serious as the days go by,” Trump said, adding that no final decision had been taken on launching military action.

Trump says diplomacy remains an option

Trump said the United States remained prepared for military action if required but indicated that ongoing talks could still lead to an agreement.

“We’re locked and loaded and ready to go. But we’re talking to them, so I think while we’re talking, we’ll see what comes of it. I believe they’re very serious. They should be,” he said.

The US President also warned that Iran would face a “much higher level” of strikes if negotiations failed, while reiterating that preventing Tehran from developing a nuclear weapon remained his key red line.

The United States has said its military operations are aimed at preventing Iran from closing the strategically important Strait of Hormuz. Iran, meanwhile, has carried out retaliatory strikes on US bases, with four American service members reported killed.

Reports claim Trump discussed large-scale military operation

Trump’s remarks came after media reports suggested he met senior advisers to discuss the possibility of a large-scale military operation against Iran. Another report said he was considering a “massive attack”, although Trump did not confirm those reports during his interaction with journalists.

He also acknowledged that the prolonged conflict, which he had earlier expected to last only a few weeks, was approaching its fifth month and had become a political challenge ahead of the US midterm elections scheduled for November.

Trump issues warning over support for Iran

Trump also addressed reports claiming that Russia and China were providing intelligence or military support to Iran. He said both Chinese President Xi Jinping and Russian President Vladimir Putin had assured him they would not arm Tehran.

“I think they wouldn’t want to have me disappointed,” Trump said.

In a separate post on his Truth Social platform, Trump warned Moscow and Beijing against supplying weapons to Iran, saying such a move would not be in their interests.

He further stated that Xi had assured him during their meeting in Beijing in May that China would not provide weapons to Iran, while Putin had conveyed a similar position despite the ongoing war in Ukraine.

For second time, US strikes ship with Indian crew near Strait of Hormuz

Strait of Hormuz

The United States Central Command (CENTCOM) has said that an oil tanker carrying Indian crew was drifting with its engine switched off near the Strait of Hormuz before it was struck by US forces.

A CENTCOM spokesperson said the vessel had stopped due to engine failure and was drifting after its crew repeatedly sought additional time to carry out repairs. US officials said the tanker was struck only after it failed to comply with directives issued by US forces enforcing a blockade on vessels allegedly transporting Iranian oil. The military said the strike was aimed at disabling the ship by targeting its engine room rather than sinking it.

The incident involved a tanker carrying Indian seafarers near the Gulf of Oman, close to the Strait of Hormuz, one of the world’s busiest maritime trade routes. The strike triggered a fire onboard, prompting rescue efforts by Omani authorities and maritime agencies. Indian authorities closely monitored the situation and coordinated with local officials regarding the welfare of the crew members.

The incident has drawn concern in India, with the government emphasising the safety of Indian nationals working aboard commercial vessels in the conflict-hit region. The Ministry of External Affairs has remained in touch with the authorities concerned as tensions between the United States and Iran continue to pose risks to international shipping.

In June, three Indian sailors were killed in a US strike on another oil tanker. The Strait of Hormuz handles a significant share of the word’s oil trade, and the latest incident has renewed concerns over the security of merchant vessels operating in the region. Maritime experts have warned that escalating hostilities could further disrupt commercial shipping and endanger civilian crews navigating one of the world’s most strategically important waterways.

Trump announces phased tariff of up to 200% on generic drug imports, India may face impact

US President Donald Trump has announced a phased tariff plan on imported generic medicines, raising duties to 200% after three years, a move that could affect India’s pharmaceutical exports.

Donald Trump

The United States has announced a phased tariff plan for imported generic medicines that could have implications for pharmaceutical exporters, including India. US President Donald Trump said the policy is intended to encourage companies to shift generic drug manufacturing to the United States by imposing steep tariffs after a two-year transition period.

The announcement is particularly important for India, one of the world’s largest suppliers of affordable generic medicines and a major exporter to the US market.

Trump outlines phased tariff plan

In a post on his Truth Social platform, President Trump said the new policy will take effect from August 1, 2026. Under the plan, imported generic medicines will continue to attract zero tariffs for the first two years.

Beginning in the third year, the tariff will increase to 100%, before rising further to 200% thereafter.

Trump said the measure is designed to encourage pharmaceutical companies to establish manufacturing facilities in the United States instead of relying on imports.

He added that companies choosing not to invest in US-based production during the transition period would face the higher tariff rates. According to Trump, the existing policy governing patented, branded and innovative medicines will remain unchanged.

Why India could be affected

India is widely regarded as the “pharmacy of the world” because of its large-scale production and export of generic medicines.

Indian generic drugs account for nearly 40% of the US generic medicine market by volume. According to a Global Trade Research Initiative (GTRI) report, India exported pharmaceutical products worth USD 9.7 billion to the United States during the 2024-25 financial year, representing around 38% of the country’s total pharmaceutical exports of USD 25.8 billion.

However, the immediate impact of the newly announced tariff policy on Indian pharmaceutical companies remains uncertain.

Existing trade agreement and industry concerns

India and the United States struck a trade pact in February that states India would receive negotiated outcomes regarding generic pharmaceuticals and pharmaceutical ingredients.

Despite that provision, previous tariff threats by Trump had already raised concerns within the pharmaceutical industry over the future of affordable medicine exports from India.

Indian pharmaceutical companies supply a wide range of generic medicines used to treat conditions including hypertension, diabetes, depression, cancer, infectious diseases and mental health disorders.

According to a Financial Post report cited in the source material, around 65% of birth control pill prescriptions in the United States during 2024 were manufactured by two India-based companies — Glenmark Pharmaceuticals Ltd. and Lupin Ltd.
