Studying till late in the night will only fetch poor grades and it is high time to tailor students' class schedules to their natural biological rhythms, stress researchers. Students whose circadian rhythms were out of sync with their class schedules -- say, night owls taking early morning courses -- received lower grades due to "social jet lag," a condition in which peak alertness times are at odds with work, school or other demands.

"We found that the majority of students were being jet-lagged by their class times, which correlated very strongly with decreased academic performance," said study co-lead author Benjamin Smarr from the University of California-Berkeley.

To reach this conclusion, the team tracked the personal daily online activity profiles of nearly 15,000 college students as they logged into campus servers.

After sorting the students into "night owls," "daytime finches" and "morning larks" -- based on their activities on days they were not in class -- researchers compared their class times to their academic outcomes.

In addition to learning deficits, social jet lag has been tied to obesity and excessive alcohol and tobacco use, said the study published in the journal Scientific Reports.

"Our research indicates that if a student can structure a consistent schedule in which class days resemble non-class days, they are more likely to achieve academic success," said study co-lead author Aaron Schirmer, an associate professor of biology at Northeastern Illinois University.

Previous studies have found that older people tend to be active earlier while young adults shift to a later sleep-wake cycle during puberty.

Overall, men stay up later than women, and circadian rhythms shift with the seasons based on natural light.

Finding these patterns reflected in students' login data spurred researchers to investigate whether digital records might also reflect the biological rhythms underlying people's behaviour.

The results suggest that "rather than admonish late students to go to bed earlier, in conflict with their biological rhythms, we should work to individualise education so that learning and classes are structured to take advantage of knowing what time of day a given student will be most capable of learning," Smarr said.

"Different people really do have biologically diverse timing, so there isn't a one-time-fits-all solution for education," he added.

New Delhi: The United States Securities and Exchange Commission (SEC) has sought assistance from the Indian government to serve a complaint to Adani Group Chairman Gautam Adani and his nephew Sagar Adani in an alleged $265 million bribery and fraud case, Reuters reported on Wednesday.

The SEC informed a district court in New York that it was attempting to serve the complaint and had requested help from India’s law ministry.

In November, the United States Attorney’s Office for the Eastern District of New York indicted Gautam Adani in connection with the case. The US Department of Justice accused executives of the conglomerate of bribing Indian officials for solar energy contracts and misrepresenting anti-bribery practices to US investors. It alleged that details of the bribes were concealed to secure financing.

The Adani Group has denied the allegations and announced plans for legal action. In December, Gautam Adani blamed the media for what he called "incorrect and reckless reporting" on the issue.

While the indictment document outlines conspiracy to obstruct justice and violations of the Foreign Corrupt Practices Act (FCPA), Adani and his executives were not formally charged under these counts. However, it names Gautam Adani, Sagar Adani, and Cyril Cabanes of Azure Power Global in connection with the alleged bribery scheme.

On November 27, the Adani Group clarified in a stock exchange filing that Gautam Adani and Sagar Adani had been charged with securities fraud, not bribery. The charges led to a significant decline in the group’s market value, with shares losing $54 billion at the time.

On November 29, the Union government stated that it considered the matter a legal issue involving private companies, individuals, and the US Justice Department.

Meanwhile, on February 10, US President Donald Trump signed an executive order pausing prosecutions of Americans accused of bribing foreign officials for business deals. The order temporarily halts enforcement of the FCPA and directs US Attorney General Pam Bondi to review the law’s enforcement guidelines.

The move is seen as a potential relief for the Adani Group, as it could delay or weaken ongoing investigations against its executives.
