Tokyo, November 29, 2016: In an important step towards the search for extra-terrestrial life, astronomers in Japan have observed the transit of a potentially habitable Earth-like extra-solar planet known as K2-3d.

A transit is a phenomenon in which a planet passes in front of its parent star, blocking a small amount of light from the star, like a shadow of the planet.

While transits have previously been observed for thousands of other extra-solar planets, K2-3d is important because there is a possibility that it might harbour extra-terrestrial life, the researchers said.

The group of researchers from the National Astronomical Observatory of Japan (NAOJ) and University of Tokyo, among others, observed the transit using the MuSCAT instrument on the Okayama Astrophysical Observatory 188-cm telescope.

K2-3d is an extra-solar planet about 150 light-years away that was discovered by the NASA K2 mission (the Kepler telescope’s “second light”).

About 30 potentially habitable planets that also have transiting orbits were discovered by the NASA Kepler mission, but most of these planets orbit fainter, more distant stars.

Because it is closer to Earth and its host star is brighter, K2-3d is a more interesting candidate for detailed follow-up studies, the researchers said.

By observing its transit precisely using the next generation of telescopes, such as Thirty Meter Telescope (TMT), the scientists expect to be able to search the atmosphere of the planet for molecules related to life, such as oxygen.

The study, published in The Astronomical Journal, also succeeded in measuring the orbital period of the planet with a high precision of about 18 seconds.

This greatly improved the forecast accuracy for future transit times. So now researchers will know exactly when to watch for the transits using the next generation of telescopes.

K2-3d’s size is 1.5 times the size of the Earth. The planet orbits its host star, which is half the size of the Sun, with a period of about 45 days.

Compared to the Earth, the planet orbits close to its host star (about one-fifth of the Earth-Sun distance).

But, because the temperature of the host star is lower than that of the Sun, calculations showed that this is the right distance for the planet to have a relatively warm climate like that of the Earth’s. (IANS)

Apart from damaging the lungs, the virus can also cause acute myocardial injury and chronic damage to the cardiovascular system.

By TS Kler

COVID-19 has led to complications and health risks manifold for patients with non-communicable diseases. Almost 75-80 percent of the COVID patients don't require hospitalisation and can recover at home with teleconsultation, but COVID-19 infections can leave the patient with long-term side effects. There are many instances where symptoms of COVID-19 have persisted for several months. Apart from damaging the lungs, the virus can also cause acute myocardial injury and chronic damage to the cardiovascular system.

According to research published in the European Heart Journal, Covid-19 patients who suffer cardiac arrest have a higher possibility of dying as compared to those who are not infected with it, and especially women are at an increased risk of death for the same reason. The virus may directly breach the ACE2 receptor cells, within the myocardium tissue and cause direct viral harm. COVID can result in inflammation of the heart muscles which is known as myocarditis and it can lead to heart failure over time, if not taken care of.

People with a pre-existing heart problem need to be extra cautious. A significant number of patients have suffered cardiac arrest during the recovery period, often resulting in death. Expert suggests that even though the COVID virus wanes, the immune response continues to be hyper-active and that often ends up attacking other organs. It has been observed that almost 80 per cent of these patients have had cardiac arrests 2-3 weeks after testing COVID positive.

When we are experiencing loneliness, it can be easy to slip into the habit of saying no to social activities.

By N. Lothungbeni Humtsoe

The festive season is a time of joy. Some people truly love it, but for many, it can trigger feelings of loneliness and anxiety. Feeling lonely is common and completely normal -- whether or not we're living through this pandemic. The social pressure to "be happy" can be relentless, but it is important to take a proactive approach to meet not only our emotional needs but also to maintain our mental stability and well-being. With the pandemic, holidays are likely to be challenging, instead, meet them head-on with a renewed dedication and a proactive mindset to avoid 'holiday blues'.

Kanchan Rai, Mental and Emotional Well-being Coach, Founder, Let Us Talk, mentions ways to turn your loneliness into action this season:

Say yes to socializing: When we are experiencing loneliness, it can be easy to slip into the habit of saying no to social activities. Seclusion can make it challenging to feel driven and the mere thought of physically seeing people can lead to stress. Hence it is recommended to saying yes to mingling to help build your confidence. Something as simple as going for a walk with a friend or chatting with your loved ones over the phone can make a huge difference.

Ahead of the Windows 11 launch, Microsoft is rolling out some updates to Edge

Ahead of the Windows 11 launch, Microsoft is rolling out some updates to Edge that include the addition of tab groups. Users will be able to assemble collections of tabs to make their browser a little less chaotic.

To create a group, hold the control button and choose the tabs you want to include, then select "Add tabs to new group" from the right-click menu, Engadget reported on Friday. Users can customise the label with a different colour for each group. When users hover over a tab, they will be able to see a preview of the web page as well.

Microsoft Edge is also getting some handy shopping features, the report said. The browser can give swift access to reviews and ratings for more than 5 million products. When users are on a product page, they can click the blue tag on the address bar and see expert reviews from reliable sources, as well as the average consumer star rating from various retailers.

When they do figure out what to buy, Microsoft aims to help them complete the transaction a bit faster. The new personalised news feed called Microsoft Start is integrated into the browser. Users will see headlines and articles relevant to their interests from a range of publishers when they open a new tab. (IANS/ MBI)
