A newly developed Artificial Intelligence-powered system is capable of automatically analysing MRI scans, accurately detecting the severity of knee osteoarthritis within a limited time, and even predicting potential disease progression if timely treatment is not undertaken

Unlike trees, bamboos, which have hollow culms and fibrous tissues, seldom get fossilised. That makes the Imphal Valley bamboo fossil remarkable — not only does it retain structural features such as nodes, internodes, and nodal buds, but it also preserves scars of thorns, details that almost never survive fossilisation

While suicide rates are generally similar among males and females in the 15-29 years age group in India, the suicide rates during 2014 and 2019 among female adolescents aged 14-17 years in India were two-six times higher than other Southeast Asian countries, while suicide rates among male adolescents were in line with global average

Traditionally, scientists estimate lake volume using satellite images and some empirically derived mathematical formulae. But these approaches often rely on rough assumptions. The recent work showed that these methods can be off by more than 1,000% in some Himalayan lakes. The implication: some lakes hold huge volume of water, possing a risk of glacial lake outburst floods

The resolution to suspend Israel from future International Olympiad on Astronomy and Astrophysics (IOAA) editions over its military actions in Gaza was taken by an overwhelming majority of the international board consisting of over 120 individuals from 63 different countries

A geothermal spring located at an elevation of about 4,980 metres above mean sea level (msl) has a slightly higher temperature of 8-10 degrees C. Higher geothermal heat flow significantly increases both basal temperatures and water content, thus accelerating ice melting

Programmed cell revival offers immense medical promise — from faster recovery after a stroke or heart attack to regenerating tissues in degenerative diseases. Instead of replacing damaged organs, doctors might one day coax the body to heal itself by awakening the new-found hidden programme

Genetic screening can accurately tell whether a foetus will develop transfusion-dependent thalassemia or non-transfusion-dependent thalassemia. A genetic counsellor can guide couples who are carriers of certain types of thalassemia to avoid abortion since these variations do not produce a transfusion-dependent thalassemia

Beyond the beautiful auroras, the most intense geomagnetic storm of May 10, 2024, which was driven by a rare sequence of six successive Earth-directed coronal mass ejections (CMEs), reached its peak roughly eight-nine hours after onset, and took around four-five days to fully recover. Its impacts were felt both in space and on the ground

20% or more of sudden cardiac deaths in young individuals can be attributed to inherited genetic conditions. These are not the typical cases we associate with heart disease. Instead, the root lies in subtle molecular errors. The science is clear, and the tools are available. What is needed now is awareness and action to sve lives

A preliminary study carried out in 2023 found nearly 1,500 dogs across 14 locations in Delhi spread over a total area of 2.8 sq. km. This roughly translates to an average density of 550 free-ranging dogs per sq. km. When extrapolated to the entirety of Delhi (1,500 sq.km), this translates to over 8.25 lakh street dogs

Liquid biopsy offers a suite of benefits that are hard to match with tissue sampling, such as minimal invasiveness, repeatability, being more comprehensive, faster turnaround time, and cost-effectiveness

In Chennai, there is over 50% increase in PM2.5 concentration during the days when aerosols are transported from north India. The regional transport of aerosols from north India occurs for two to four days at a stretch twice or thrice a month during the period December to March
