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.

Ranchi(PTI): The Rashtriya Janata Dal (RJD) has emerged as a surprise element in the Jharkhand assembly elections with its candidates leading in five of the six seats where the party is contesting, according to trends available on the Election Commission's website on Saturday.

RJD candidates in five assembly seats were leading over sitting BJP legislators.

In 2019, RJD had secured only the Chatra seat where its nominee Satyanand Bhokta won.

In Deoghar, RJD’s Suresh Paswan was leading by 19,581 votes over his nearest rival and BJP's sitting MLA Narayan Das after the third round of counting.

RJD’s Sanjay Prasad Yadav was ahead by 19,867 votes in Godda over BJP MLA Amit Kumar Mandal after the sixth round of counting.

In Koderma, RJD nominee Subhash Prasad Yadav, who was out on bail, was leading by a margin of 3,471 votes over BJP’s sitting legislator Neera Yadav.

Subhas Prasad Yadav, considered to be one of the close aides of RJD supremo Lalu Prasad, was recently granted bail by the Supreme Court in a money laundering case.

Party’s Naresh Prasad Singh was leading by 5,159 votes after the fourth round of counting over BJP’s Bishrampur MLA Ramchandra Chandravanshi.

RJD's Sanjay Kumar Singh Yadav was also leading from Hussainabad by 8,213 votes after the fourth round of counting over BJP MLA Kamlesh Kumar Singh.

Party’s candidate Rashmi Prakash, however, was trailing from Chatra by 3,776 votes.

Bhokta did not contest the elections this time, and his daughter-in-law Prakash was given a ticket.
