Scientists test menstrual products with blood for the first time, and find surprises

Blood really is thicker than water – yet makers of menstrual products have traditionally used saline to estimate how much liquid they can hold. The capacity to absorb of traditional menstrual products is a common way to measure the amount of blood lost. Clinicians use it to diagnose heavy menstrual bleeding, which affects roughly a…

Science This Week | India launches Aditya-L1 to study the sun, Pragyan safely parked and more

Aditya L1, India’s first ever solar mission, was launched by the ISRO on Saturday at SDSC-SHAR, Sriharikotta in Andhra Pradesh. The spacecraft will be positioned within a ‘haloo orbit’ around Lagrange point 1 (L1) in the Sun-Earth system, located approximately 1.5 million km away from Earth. Study will be conducted of Chromospheric and coronal heating,…

Oldest yet fossils of a plant-eating dinosaur found in Rajasthan

In a paper published recently in Scientific Reports, scientists from IIT Roorkee have characterised dinosaur fossils from the Middle Jurassic period, found in the Thar desert near the Jaisalmer Basin by the Geological Survey of India. They discovered that they had uncovered remains of a sauropod dinosaur, which is the same clade as the long-necked…

Chest X-ray interpretation using AI can detect more TB cases

India has a powerful technology — AI-assisted chest X-ray — to screen presumptive TB cases. The AI algorithm (qXR), which was developed by the Mumbai-based Qure.ai, can help in early detection of people with presumptive TB disease in less than a minute, including people with subclinical TB. As per the 2019-2021 National TB prevalence survey…

Is the bat’s brain wired for collective behaviour?

Posted on By admin
Is the bat’s brain wired for collective behaviour?

The same neurons that help bats navigate through space may also help them navigate collective social environments (Nature). Many mammals, including bats and humans, are believed to navigate with the help of a brain structure called the hippocampus, which encodes a mental ‘map’ of familiar surroundings. For example, as one walks around the neighbourhood or…
