The Enforcement Directorate (ED) has summoned representatives from both Google and Meta to appear on July 28, 2025, as part of an ongoing investigation into illegal online betting advertisements. This follows the companies’ previous request for additional time to present required legal documents during an earlier meeting. The ED’s inquiry targets how these platforms have facilitated surrogate advertising and the promotion of illegal betting apps, which have reportedly led to significant financial losses for users across various age groups.

The investigation reveals alarming statistics about the online betting landscape in India. Approximately 22 crore individuals use betting applications, with 11 crore classified as regular users. In the first quarter of 2025 alone, illegal betting websites received around 1.6 billion visits. The online betting market in India has ballooned to an estimated $100 billion, growing at a staggering annual rate of 30 percent. Additionally, these platforms are evading tax payments estimated at around ₹27,000 crore each year.

Impact of Illegal Betting on Society

The ramifications of these illegal betting practices extend beyond financial losses. The World Health Organization (WHO) recognizes gambling addiction as a mental disorder, associated with severe psychological impacts such as depression and stress. Tragically, reports indicate that thousands of individuals, including students and homemakers, have taken their own lives due to the pressures stemming from online betting losses. A public interest litigation filed in Telangana highlights that at least 1,023 suicides have been connected to this crisis, with a significant number occurring in the state itself.

The ED’s investigation is not limited to tech giants. Prominent Telugu actors involved in promotional campaigns for these betting applications have also been summoned to provide testimony. This action is part of a broader effort to hold accountable those who contribute to the proliferation of irresponsible advertisements that target vulnerable populations, particularly youth.

Calls for Stricter Advertising Regulations

There is a growing consensus that both Google and Meta have a responsibility to scrutinize the entities they authorize for advertising. Given the serious consequences of online betting in India, calls for stricter regulations on advertising practices are intensifying. The current landscape raises significant ethical concerns, as algorithms used by these platforms often exploit the vulnerabilities of young users, leading to addictive behaviors that can dismantle lives.

As the ED continues its investigation, the future of advertising for betting applications hangs in the balance. The actions taken by regulatory authorities may set a precedent for how digital platforms manage content and advertisements, particularly in markets where the impact of gambling is profound and far-reaching.

Scientists at the National Institute of Standards and Technology (NIST) have developed the most accurate atomic clock to date, capable of measuring time with an unprecedented precision that could last for billions of years without losing a second. This groundbreaking achievement, revealed in March 2024, utilizes advanced quantum logic techniques, marking a significant milestone in the field of precision measurement.

This revolutionary atomic clock is based on aluminum ions and boasts an accuracy rate that surpasses previous models by a staggering 41%. It is also 2.6 times more stable than any ion clock previously constructed. Researchers achieved this remarkable precision through a combination of laser tuning and innovative vacuum chamber engineering.

Mason Marshall, a researcher at NIST and the lead author of the study published in Physical Review Letters, expressed excitement about this significant advancement, stating, “It’s exciting to work on the most accurate clock ever. At NIST, we get to carry out these long-term plans in precision measurement that can push the field of physics and our understanding of the world around us.”

Innovative Techniques for Enhanced Precision

The clock operates by pairing an aluminum ion with a magnesium ion, leveraging their unique properties to create an exceptionally precise timekeeping system. Aluminum is known for its steady atomic ticks, which are less affected by environmental factors such as temperature and magnetic fields compared to traditional cesium clocks. However, aluminum’s interaction with lasers posed a challenge.

Researchers addressed this issue by introducing magnesium, which is more compatible with laser techniques. In this setup, magnesium assists in cooling the aluminum ion and reflects its movements, allowing scientists to monitor the aluminum’s clock state through magnesium’s behavior. This innovative dual-ion system ultimately enhances the reliability and accuracy of the clock.

One of the primary challenges in developing this atomic clock was the design of the ion trap, which holds the ions in place. Initially, tiny vibrations, known as excess micromotion, disrupted the ions’ ticking rhythm. To rectify this, scientists redesigned the trap’s base using a thicker diamond wafer for increased stability and adjusted the gold coatings on the electrodes. These modifications minimized resistance and created a more stable environment for the ions, allowing for consistent and precise timekeeping.

Tackling Challenges for Improved Functionality

Despite its advanced design, the atomic clock faced interference from traces of hydrogen escaping from the steel vacuum chamber, which interfered with the ions’ ticking. To combat this, the team upgraded the chamber material to titanium, successfully reducing hydrogen levels by 150 times. This change enabled the clock to operate for extended periods without interruption, significantly enhancing its performance.

Additionally, the researchers required a super-stable laser to ensure accurate measurements of the ion’s ticks. The previous version of the clock relied on extensive averaging over weeks to smooth out quantum jitters. The NIST team collaborated with Jun Ye and his group at JILA, utilizing one of the most stable lasers globally, which had already been employed in the record-setting Strontium 1 lattice clock.

This collaboration involved a 3.6-kilometer underground fiber-optic connection to transmit the ultra-stable laser, ensuring precise synchronization of the aluminum ion clock’s laser. As a result, the time required for ion probing improved from 150 milliseconds to one full second, and the measurement speed increased dramatically, allowing for ultra-precise counting down to the 19th decimal place in just 1.5 days instead of three weeks.

This atomic clock not only sets new standards in timekeeping but also has broader implications. It has the potential to redefine the official length of a second and serve as a platform for exploring new clock architectures and quantum physics applications. Moreover, it could assist in Earth geodesy, providing precise measurements of Earth’s shape and gravitational field, and enable investigations into fundamental questions about the constants of nature.

With the advancement of this atomic clock, NIST researchers are poised to explore new horizons in precision measurement and quantum technology, paving the way for future innovations in the field. The findings represent a significant leap forward in both scientific understanding and practical applications of atomic timekeeping.
