How are semiconductors fabricated? | Explained

While the physical realm of human activity contains an array of languages, the digital realm is founded on just one fundamental binary language: the 1s and 0s, also called the bits of data. Computers represent these bits as electrical signals and this forms the foundation of modern computing, communication, social media, robotics, and artificial intelligence….

Dispersal out of Africa may have occurred during arid period

The most recent and widespread migration of humans out of Africa, which occurred less than 1,00,000 years ago, may have taken place during a particularly arid period following the Toba supervolcano eruption in Indonesia, a new study published in the journal Nature suggests. It is typically thought that the dispersals of humans out of Africa…

Does a specific bacteria subtype drive colorectal cancer progression?

Researchers have found that a specific subtype of a microbe commonly found in the mouth is able to travel to the gut and grow within colorectal cancer tumours. This microbe is also a culprit for driving cancer progression and leads to poorer patient outcomes after cancer treatment. The findings could help improve therapeutic approaches and…

Using AI to classify neem fruits based on azadirachtin content

The AI-based approach makes analytical equipment like high-performance liquid chromatography redundant. Researchers at the School of Biotechnology, Jawaharlal Nehru University, New Delhi have developed an Artificial Intelligence-based tool to predict the level of metabolite content in neem fruits as either low or high based on images of neem leaves and fruits. The AI-based approach makes…

Anaemia prevalence in eight States found to be overestimated

A study across eight States in India involving 4,613 participants that included adolescents (647 girls and 674 boys), adults (931 women and 927 men) and elderly (714 women and 720 men) has found that the prevalence of anaemia has been overestimated by previous surveys. While the NFHS surveys measured haemoglobin using finger prick-based capillary blood,…
