Science Weekly! 30th May 2021.

Let’s have look at some awesome science insights of the week.

1.New evidence of how and when the Milky Way came together :

New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy. Using relatively new methods in astronomy, the researchers were able to identify the most precise ages currently possible for a sample of about a hundred red giant stars in the galaxy.

2.Optimizes body’s own immune system to fight cancer :

A new study shows how engineered immune cells used in new cancer therapies can overcome physical barriers to allow a patient’s own immune system to fight tumors. The research could improve cancer therapies in the future for millions of people worldwide.

3.Antarctic ice sheet retreat could trigger chain reaction :

The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests. The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.

4.The cerebellum may have played an important role in the evolution of the human brain :

The cerebellum — a part of the brain once recognized mainly for its role in coordinating movement — underwent evolutionary changes that may have contributed to human culture, language and tool use, according to a new study.

5.Lightning and subvisible discharges produce molecules that clean the atmosphere :

Scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical and hydroperoxyl radical. The hydroxyl radical is important in the atmosphere because it initiates chemical reactions and breaks down molecules like the greenhouse gas methane.

6.A giant, sizzling planet may be orbiting the star Vega :

Vega, one of the brightest stars in the night sky, may play host to a giant planet with average surface temperatures of 5,390 degrees Fahrenheit.

7.Memory details fade over time, with only the main gist preserved :

What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now researchers have been able to provide some answers. Their new study, which is published today in Nature Communications, demonstrates that our memories become less vibrant and detailed over time, with only the central gist eventually preserved. Moreover, this ‘gasification’ of our memories is boosted when we frequently recall our recent experiences.
