Editor’s Note
Science magazines help the students to get the latest science news from an editorially independent, reliable source. Students learn the science behind the latest discoveries and research. They tell scientists about recent scientific discoveries in the same way newspapers tell us about recent events. This magazine helps students to provide the latest updating events in science fortnightly.

The findings could suggest it's possible to learn simple information while snoozing.
Your Brain Pays Attention to Unfamiliar Voices, Even While You Sleep
Even when sleeping deeply you are more aware of what is going on around you than you might realize. New research suggests that the human brain is constantly monitoring its surroundings, including processing sounds, to decide if you need to wake up -- it could even let you learn in your sleep.
Manuel Schabus, a neuroscientist at the University of Salzburg in Austria, and his colleagues wanted to see what kind processing the brain could do while asleep. The researchers played a recording while their adult test subjects slept through a night. The recording included familiar and unfamiliar voices speaking different names, including the subject's own name. Whether the name was the subject's own or something different had no effect on brain activity. But the familiarity of the voice made a big difference.

Eight hours sleep!
And you must eat breakfast!
Breakfast literally means “to break the fast.” It is the first meal of the day after a stretch of not eating overnight.
Breakfast earned its title as the most important meal of the day back in the 1960s after American nutritionist Adelle Davis suggested that to keep fit and avoid obesity, one should “eat breakfast like a king, lunch like a prince, and dinner like a pauper.”
Though a recent study of 30,000 adults found that 15% regularly skipped breakfast, many still believe it to be the most important meal of the day. Breakfast provides the body with important nutrients, to start the day feeling energized and nourished. Many also believe that it can promote weight loss.
But is breakfast really the most important meal of the day?
As with most things in nutrition, the answer is complex. While some research suggests that skipping breakfast is not harmful, other research suggests otherwise.
Eating regular meals and snacks, including breakfast, allows for more opportunities throughout the day to give the body the energy and nutrients it needs to function optimally.

Looking After your Mental Health
Dr Aehsan Ahmad Dar, Assistant Professor, Department of Psychology, published the article titled “A Cross-Sectional Study on Mental Health of School Students during the COVID-19 Pandemic in India”.
The present study estimated the mental health of school students during the COVID-19 pandemic. The findings revealed that the COVID-19 pandemic caused stress which increased the levels of anxiety and depression among the students. However, social support from family and friends was found to be a protective factor for mental health.
The findings of the research will serve as a reliable source of information for mental health professionals and policymakers to better understand the impact of the COVID-19 pandemic and other traumatic experiences on mental health. Therefore, necessary efforts are suggested to provide mental health support services to prevent the development of mental disorders.
Here are tips and advice that we hope you will find useful.

Education Trends in 2023
METAVERSE MEETS REALITY
The tech industry has come a long way from a mere PC in the first phase to the interactive sleek smart mobile phones in the second and now graduating to the 3D highly interactive augmented reality.
The boundaries of time and space no longer apply to the modern education sector. From primary to higher education, online and cloud-based delivery learning platforms are becoming more prevalent as a result of the exponential acceleration of the digital transformation in the education sector.
Online learning will be more real with the help of metaverse, which involves the concept of Augmented and Virtual Reality (AR & VR).
In the post-pandemic environment, Metaverse may be a tremendous resource for remote learning and operations, support remote operations and training effectively, and advance the sustainability agenda.

Now heart transplant will be easy. Artificial hearts can be implanted in serious patients. IIT Kanpur and cardiologists from across the country have developed this artificial heart. Trial on animals will start from February or March. After success in the trial, transplantation can be done in humans in the next two years. Artificial heart is being developed to reduce the sufferings of the patients.
A team of 10 scientists and doctors has prepared this artificial heart. After the success of the trial on animals, heart transplantation in humans will begin within two years.
IIT Kanpur Develops Artificial Heart to Deal with Acute Cardiac Problems
The programme has been launched in collaboration with nation’s leading hospitals and will be steered by a team of innovators with relevant experience selected under the mentorship of a task force comprising industry experts. The project was seed-funded by Padma awardee Sudha Murthy and the Indian Council of Medical Research
IIT Kanpur is ready with an artificial heart that would be of great help to people with acute cardiac problems

Newfound ‘hot Jupiter exoplanet celebrates New Year’s every 5 days
Still suffering from a New Year hangover? How would you feel doing it all again in less than a week? If you lived on a newly-discovered exoplanet, you'd have to do just that: Astronomers have spotted a planet three times the size of Jupiter orbiting a rapidly-spinning dwarf star around 530 light-years from Earth that celebrates a trip around its sun every five days!
This newfound exoplanet, designated TOI-778 b, is an example of a so-called "hot Jupiter," a world similar to our solar system's largest planet, the gas giant Jupiter, but located in extreme proximity to its star. This proximity gives rise to extreme conditions such as surface temperatures hot enough to vaporize iron and orbits of under ten Earth days.
The planet discovered by NASA’s TESS is s scorcher and whips around its star in under five days.
This particular hot Jupiter orbits its star TOI-778 at a distance of around 5.6 million miles (9 million kilometers). This is much closer than even our solar system's innermost planet Mercury is to the sun at approximately 29 million miles (46 million km) away from our star.

James Webb Space Telescope captures chaotic cosmic collision
Webb caught sight of a galactic get-together known as II ZW96
The James Webb Space Telescope has captured a pair of galaxies distorting each other as they merge in a great galactic get-together.
The ongoing cosmic collision imaged by Webb is known as II ZW 96. It is roughly 500 million light-years from Earth and located in the constellation Delphinus, according to a Nov. 30 NASA statement.
The image was created by Webb bringing to bear its cutting-edge NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) payloads on II ZW 96 and details how the shape of both galaxies are being distorted by their respective gravitational attraction.
