Night Shift can cause DNA damage: Study

[vc_row][vc_column][vc_column_text]Do you frequently work in night shifts? Lack of proper sleep and night-time wakefulness can cause damage to the structure of the human DNA and lead to many diseases, including cancer and diabetes, as well as cardiovascular, neurological and pulmonary diseases, warns a study.

The study, published in the Anesthesia academic journal, shows that DNA repair gene expression is lower at baseline among night workers and further decreases after acute sleep deprivation, which supports the postulation that night workers demonstrate impaired DNA repair.

The findings showed that people who are required to work overnight demonstrate 30 per cent higher DNA breaks as compared with those not required to work overnight, and this DNA damage is further increased by over 25 per cent after a night of acute sleep deprivation.

“Although this work is very preliminary, it is clear from the results that even a single night of sleep deprivation can trigger events that may contribute to the development of chronic disease,” said Siu-Wai Choi, of the University of Hong Kong.

“DNA damage is a change in the basic structure of DNA that is not repaired when the DNA is replicated,” said S. W. Choi.

“Double-strand breaks are particularly hazardous as repair failure causes genomic instability and cell death, whereas disrepair can lead to inappropriate end-joining events that commonly underlie oncogenic transformation,” Choi added.

For the research, the team examined a small group of healthy full-time doctors, average age between 28 and 33, who donated a sample of blood after three days of adequate sleep.

Doctors who worked the night shift then had additional blood sampled the morning after, following acute sleep deprivation.

“The study demonstrates that disrupted sleep is associated with DNA damage,” Choi said. Furthermore, larger prospective studies looking at relationships between DNA damage and chronic disease development are warranted, and methods to relieve or repair DNA damage linked to sleep deprivation should be investigated, Choi suggested.[/vc_column_text][/vc_column][/vc_row]

Flat whites are popular among coffee connoisseurs who want for less foam in their beverage as flat white is flatter than a cappuccino or latte. In many cafes across Australia and New Zealand, customers are commonly allured into having the drink by baristas who show off their skills and create beautiful artwork while the drink is prepared.

Over the years the coffee culture has changed a lot and the ways by which flat white is prepared. Earlier the flat white used to be prepared by with whole milk but nowadays the Australians and the people in New Zealand ordered it with plant-based milk including oat milk.

Google celebrates Leap Day with a Doodle

Google released a doodle on Thursday, to mark Leap Day. This unique doodle depicts a frog marked with the leap day date set amid a setting involving the dates February 28 and March 1. The Leap Day vanishes as the frog jumps. This setting is illustrated against the background of a pond with stones and leaves where the word Google can be identified in the background.

The description with this moving illustration reads Ribbiting news, its Leap Day, February 29th, only occurs about every 4 years, to keep our calenders in alignment with the Earth and the Sun. Enjoy this bonus day of February – Happy Leap Day!

Leap Day’s origin can be traced back to over 2000 years ago. This was done to align the standard Gregorian calendar with the solar calendar and it also takes into account the fact that the Earth takes slightly over 365 days to orbit the sun that is 365.2422 days to be exact.

According to the Gregorian calendar which is the world’s most widely used calendar, each leap year consists of 366 days instead of 365. This extra day, known as Leap Day, adjusts for the fact that an astronomical year is slightly less than 365 days and 6 hours. The last leap day occurred in 2020, and the next will arrive in 2028. Leap year babies will get the opportunity to celebrate their birthday on February 29 this year as the day comes only once every 4 years.

Anthony a town in Texas, USA proudly proclaims itself as the Leap Year Capital of the World and hosts a festival every Leap Year to celebrate. Just like the Leap Day helps adjust our calendar, leap seconds are occasionally added to Coordinated Universal Time (UTC) to sychronise atomic clocks with the Earth’s slowing rotation. Leap Day has featured in literature, movies, and music. One notable example is the 2010 romantic comedy film Leap Year.
