Aditya L1: India’s first space-based mission to study Sun

Posted by in category: space

Aditya L1 is India’s first space-based mission to study the Sun, which is scheduled to be launched in 2023. The spacecraft is named after Aditya, the Hindu god of the Sun. Indian Space Research Organisation (ISRO) aims to place Aditya L1 in a halo orbit around the Sun-Earth L1 Lagrange point, which is about 1.5 million kilometres from Earth.

The mission’s primary objective is to study the Sun’s corona, which is the corona is a very hot and dynamic region. Aditya L1 will carry a number of instruments to study the corona, including a coronagraph, a spectrometer, and an imager.

Astronomers reveal new features of galactic black holes

Posted by in categories: cosmology, materials

Black holes are the most mysterious objects in the universe, with features that sound like they come straight from a sci-fi movie.

Stellar-mass with masses of roughly 10 suns, for example, reveal their existence by eating materials from their companion stars. And in some instances, accumulate at the center of some galaxies to form bright compact regions known as quasars with masses equal to millions to billions of our sun. A subset of accreting stellar-mass that can launch jets of highly magnetized plasma are called microquasars.

An international team of scientists, including UNLV astrophysicist Bing Zhang, reports in Nature on a dedicated observational campaign on the galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen.

Simple Brain Hack Could Boost Learning and Improve Mental Health

Adopting a curious mindset over a high-pressure one can enhance memory, according to recent research from Duke University. The study showed that participants who envisioned themselves as a thief planning a heist in a virtual art museum demonstrated better recall of the paintings they encountered than those who imagined executing the heist on the spot while playing the same computer game.

The slight variation in motivations — the urgent need to achieve immediate goals versus the curious exploration for future objectives — could have significant implications in real-life scenarios. These include incentivizing people to receive a vaccine, prompting action against climate change, and potentially providing new treatments for psychiatric conditions.

The findings were recently published in the Proceedings of the National Academy of Sciences.

Boning Up on the Unique Genetics of the Human Skeletal System

Posted by in categories: biotech/medical, computing, genetics, neuroscience

Humans have a distinctive skeleton, and are the only bipedal great apes (the great ape species are bonobos, chimpanzees, gorillas, orangutans, and humans). While the evolution of the human skeleton enabled us to walk upright, it also led to the rise of musculoskeletal disease. It’s thought that cognitive development began to accelerate in humans once we started to move around, adapt to new environments, and make use of tools. Researchers have now used advanced computational tools and a trove of human genetic data in the UK Biobank to outline the genetic changes that occurred as primates started to walk upright for the first time.

These findings, which were reported in Science, have suggested that natural selection had a strong influence on the genetic changes that altered our anatomy, and gave early humans an evolutionary leg up.

Worldcoin struggles to find new users willing to scan iris for crypto

The stark contrast in the number of sign-ups before and after the launch suggests a lack of enthusiasm. However, the early on-boards also proved controversial, with one MIT report suggesting that the developers behind the project attracted the first million using deception, cash handouts and more, especially in developing countries where data laws are notably weak.

Worldcoin has drawn scrutiny and commentary from many well-known names in the crypto community, including Ethereum co-founder Vitalik Buterin and Twitter co-founder Jack Dorsey. In its defense, the project has maintained that it doesn’t collect personal information and can delete the biometric data upon user request.

All of the matter and radiation we measure today originated in a hot Big Bang long ago. The Universe was never empty, not even before that.
